There is really no 100 percent correct way of coding or in this case HTML/CSS, but most web designer/developers try to follow standard coding practices. If you want to decipher all the confusion then just go to https://validator.w3.org/ yourself. In my opinion HTML/CSS can pretty forgiving which can be a good or a bad thing.

I been programming since the early 1980s, but I really didn't get started with website design and development until 2009 or 2010. Like you, I was let go from a job were I spent almost 20 years working in the automotive paint business. Decided to change field and went back to college as I was collecting severance that helped. I earned a degree in Computer Graphics when I learned design first (HTML/CSS) and then started back end development PHP by teaching myself. I agree with Barand learn HTML/CSS and maybe a little JavaScript (Vanilla...no libraries like jQuery at least at first). It shouldn't take too long to learn HTML/CSS and I would advice staying away from Bootstrap until you get a firm grasp of HTML/CSS as in my opinion knowing CSS good leads to less headaches later on. Once you get a firm grasp of HTML/CSS then start tackling PHP. I recommend pure PHP and no Frameworks at first as that is just leads to taking shortcuts then when you run into a problem you might never really understanding the solution. One thing I learn the hard way is never try to write your own security code in PHP just use PHP's builtin security functions and/or use a trusted third party's application (PHPMailer or Swiftmailer comes to mind). Be very careful of tutorials on the internet and even the good ones are outdated somewhat as the programming world changes fast. That's where these types of forums come in handy. One thing over the years that I have learn first hand is designers and developers have big egos that can lead to some healthy "heated" debates. 😂 After awhile every programmer gets his or her own coding style and there's nothing wrong in that as long as it isn't fundamentally wrong.

I have done comment sections in the past in PHP and what I found useful is have two database tables. One for the main reply (thread) and the other for the replies that way if the thread should be deleted or messed up somehow (though I never had that happened) then simply delete the main thread id to the replies.

Here's my PDO connection class that have used over the years. Maybe this will help? use mysql_xdevapi\Exception; use PDO; use PDOException; class Database { private PDO $_connection; // Store the single instance. private static ?Database $_instance = null; // Don't initialize before it is called: // Get an instance of the Database. // @return Database: protected static function getInstance(): Database { if (!self::$_instance) { self::$_instance = new self(); } return self::$_instance; } public static function pdo(): PDO { $db = static::getInstance(); return $db->getConnection(); } // Constructor - Build the PDO Connection: public function __construct() { try { $db_options = [ /* important! use actual prepared statements (default: emulate prepared statements) */ PDO::ATTR_EMULATE_PREPARES => false /* throw exceptions on errors (default: stay silent) */ , PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION /* fetch associative arrays (default: mixed arrays) */ , PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC ]; $this->_connection = new PDO('mysql:host=' . DATABASE_HOST . ';dbname=' . DATABASE_NAME . ';charset=utf8', DATABASE_USERNAME, DATABASE_PASSWORD, $db_options); } catch (PDOException $e) { //echo $e; //echo "<pre>" . print_r($e->errorInfo, 1) . "</pre>"; if ($e->errorInfo[1] === 1045) { echo "User has the wrong credentials " . $e->errorInfo[1] . "<br>"; return false; } throw $e; // If PDO Exception error can't handle it throw it to Exception: } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; // Not for a production server: } return true; } // Empty clone magic method to prevent duplication: private function __clone() { } // Get the PDO connection: protected function getConnection(): PDO { return $this->_connection; } } to use simply do $stmt = Database::pdo()->prepare($sql); I just want to add this is just to add a PDO connection string to connect the Database Table, I would never send that error message on a production server.

I personally don't use bootstrap, but I'm assuming it has grids? Anyways, I use grids and HTML for a two column format. A third column would be easy as well using CSS grids. Here's the two column form using grids: <main class="content"> <div class="container"> <?php foreach ($cms as $record) { ?> <article class="cms"> <img class="article_image" src="<?= htmlspecialchars($record['image_path']) ?>" <?= getimagesize($record['image_path'])[3] ?> alt="article image"> <h2><?= $record['heading'] ?></h2> <span class="author_style">Created by <?= $record['author'] ?> on <time datetime="<?= htmlspecialchars(CMS::styleTime($record['date_added'])) ?>"><?= htmlspecialchars(CMS::styleDate($record['date_added'])) ?></time> </span> <p><?= nl2br($record['content']) ?></p> </article> <?php } ?> </div> </main> Here's a small section of the CSS: /* Approximately the size of a 1248px large display monitor */ @supports (grid-area: auto) { @media screen and (min-width: 78em) { .site { display: grid; grid-template-columns: 1fr minmax(23.4em, 54.6em); grid-template-areas: "header header" "nav nav" "main main" "sidebar sidebar" "footer footer"; justify-content: center; width: 75em; margin: 0 auto; } .masthead { grid-area: header; background-image: url(../images/img-header-001pg.jpg); background-repeat: no-repeat; } .checkStyle { grid-area: main; font-size: 1.2em; } .sidebar { grid-area: sidebar; justify-content: center; } } // End of Screen Size } // End of Last Grid Area Using grids cuts down on the CSS as well as the HTML, plus CSS really should be in a separate file and not inline. I'm assuming it's your CSS, but I'm sure you can have CSS from bootstrap that is an external fire as well that you can change?

I was bored today and decided to take a break from my own develop, so I decided to fool around with this and see if I could help. I don't know exactly what you are doing and I only used one database table to do this. However, I think what you are after can easily be modified? If not that's OK as I said I was bored. 😂 I don't know why you don't use MySQL to pull in the range values of the prices? I created a mythical Bicycle Shop called Rocket Bicycles : <table id="products"> <tr> <th colspan="4">The Rocket Bicycles Inventory</th> </tr> <tr> <th>Record</th> <th>Product</th> <th>Price (＄)</th> <th>Quantity</th> </tr> </table> and I used Vanilla JavaScript (I find that is just as easy and is easily transferable) 'use strict'; (function () { let data = {}; /* The Following can easily be put into HTML via js */ data.min = 0; data.max = 2000.00; /* Handle General Errors in Fetch */ const handleErrors = function (response) { if (!response.ok) { throw (response.status + ' : ' + response.statusText); } return response.json(); }; const productCard = function (record){ /* Get the Table Id */ const table = document.getElementById('products'); /* Create the Table Row element */ const tr = document.createElement('tr'); /* Create the necessary Elements for the column data */ const id = document.createElement('td'); const product = document.createElement('td'); const price = document.createElement('td'); const quantity = document.createElement('td'); /* Append the Table Row element to the Table */ table.append(tr); /* Append the Column Row data to the Table Rows */ tr.append(id); tr.append(product); tr.append(price); tr.append(quantity); /* Assign the appropiate class to the table data row */ /* Give the appropiate table data the corresponding data */ id.classList.add('normal_format'); id.textContent = record.id; product.classList.add('product_format'); product.textContent = record.product; price.classList.add('money_format'); price.textContent = "$" + record.price.toFixed(2).replace(/\d(?=(\d{3})+\.)/g, '$&,'); quantity.classList.add('normal_format'); quantity.textContent = record.quantity; }; /* Success function utilizing FETCH */ const inventoryUISuccess = function (records) { /* Grabing the record data from the Database Table * and assigning the value of the objects to the * HTML table using a forEach statement in * Vanilla JavaScript. */ records.forEach(record => productCard(record)); }; /* If Database Table fails to load then hard code the correct answers */ const inventoryUIError = function (error) { console.log("The Darn Database Table did not load", error); }; /* create FETCH request for check answers */ const price_range = function (url, succeed, fail) { fetch(url, { method: 'POST', // or 'PUT' body: JSON.stringify(data) }) .then((response) => handleErrors(response)) .then((data) => succeed(data)) .catch((error) => fail(error)); }; price_range('rockets_inventory.php', inventoryUISuccess, inventoryUIError); })(); the PHP for the "Fetching of the Data": <?php require_once 'assets/config/config.php'; /* Makes it, so we don't have to decode the json coming from javascript */ header('Content-type: application/json'); /* * The below must be used in order for the json to be decoded properly. */ try { $data = json_decode(file_get_contents('php://input'), true, 512, JSON_THROW_ON_ERROR); } catch (JsonException $e) { } /* * Grab the database table data that meets the price requirements */ $sql = 'SELECT id, product, price, quantity FROM rocket_bicycles WHERE price >= :min AND price <= :max ORDER BY price '; $stmt = $pdo->prepare($sql); // Prepare the query: $stmt->execute(['min' => (float)$data['min'], 'max' => (float)$data['max']]); // Execute the query with the supplied data: $result = $stmt->fetchAll(PDO::FETCH_ASSOC); /* * If everything validates OK then send success message to Ajax / JavaScript */ if (isset($result)) { output($result); } else { errorOutput('There is a darn problem!'); } /* * Throw error if something is wrong */ function errorOutput($output, $code = 500) { http_response_code($code); try { echo json_encode($output, JSON_THROW_ON_ERROR); } catch (JsonException) { } } /* * After converting data array to JSON send back to javascript using * this function. */ function output($output) { http_response_code(200);

When I first started coding in PHP there was a person on here (I can't remember his name) that helped me out a lot. I was hung up on securing my code and spent all night writing a script that I thought was "secure" then the next day I posted it here. He replied back to me and the first thing he wrote was to throw that script in the trash. He went on to say people who write security code work in teams and test them out before they are introduced to the wild (internet). There is nothing wrong with prepared statement and unless you are a large corporation the speed of prepared statements is fast enough. Prepared statements are as secure as they possibly can be and nothing is 100 percent secure. So I totally disagree on the use of prepared statement.

Remember, people are not there to see what is actually happening or what you are doing. The solution that you get that works might be something that you don't understand, but a person who helped you who put his or her time in should at least be thanked. At least you acknowledge and thanked that in the last post that you made. I once had someone help me with a PHP script that I didn't understand and even to this day still don't after deciphering it, but it worked and there wasn't another solution out there. So I used it anyways as I spent too much time on the particular part of the script. There are a lot of times I don't understand what something does, but only to have a light-bulb go on in my head months or even years later. Object-oriented programming is something that I could do, but really never understood the meat & potatoes of it until now. It's starting to make a lot of sense now and to me that is what is fun with it comes to coding.

Pagination is simple to do, but you need to actually want to learn it. Here's what I call a mini tutorial on how to do it though it uses PDO instead of mysqli, but the principle is the same. Here's a function that I wrote: /* * Pagination Format * Read all the data from the database table in an array format */ function readData($pdo, $table, $page, $perPage, $offset) { $sql = 'SELECT * FROM ' . $table . ' WHERE page=:page ORDER BY date_added DESC LIMIT :perPage OFFSET :blogOffset'; $stmt = $pdo->prepare($sql); // Prepare the query: $stmt->execute(['perPage' => $perPage, 'blogOffset' => $offset, 'page' => $page]); // Execute the query with the supplied data: return $stmt->fetchAll(PDO::FETCH_ASSOC); } Here's how to implement it: /* * Using pagination in order to have a nice looking * website page. */ if (isset($_GET['page']) && !empty($_GET['page'])) { $current_page = urldecode($_GET['page']); } else { $current_page = 1; } $per_page = 1; // Total number of records to be displayed: /* * Grab total records (rows) in a database table */ function totalRecords($pdo, $table, $page = 'blog') { $sql = "SELECT count(id) FROM " . $table . " WHERE page=:page"; $stmt = $pdo->prepare($sql); $stmt->execute([ 'page' => $page ]); return $stmt->fetchColumn(); } /* Total number of records that NEEDS to be displayed */ $total_count = totalRecords($pdo, 'cms'); /* calculate the offset */ $offset = $per_page * ($current_page - 1); /* calculate total pages to be displayed */ $total_pages = ceil($total_count / $per_page); /* Figure out the Pagination Links */ $links = links_function('index.php', $current_page, $total_pages); /* Finally, call for the data from the database table to display */ $cms = readData($pdo, 'cms', 'blog', $per_page, $offset); I don't know if it will help the OP any, but it should help others as well. 😉 I just want to add figuring out the Links isn't that hard to figure out and it shouldn't affect the pagination part, but it's pretty useless without it. I figure I can't do everything. 😉😃

While PHPStorm is subscription based, it's pretty good in my opinion and for an IDE it has helped my PHP skills a lot. It makes suggestions on how to write the code in a better way that I would never have thought of and makes syntax errors easy to resolve. I am not affiliated with JetBrains as I just like using their developer tools as it simplifies my coding a lot.

Welcome aboard, You are never too old to learn and do something that you like doing. I'm 57 years old and teaching myself Django as I am like Python3 for the simplicity of coding. Uselessness is something that isn't in a coder's vocabulary.

I personally like leaving the HTML on the page itself as I like doing HTML/CSS mock-ups then just adding to the PHP to the HTML. For example - <main> <?php foreach ($cms as $record) { ?> <article class="cms"> <img class="article_image" src="<?php echo htmlspecialchars($record['image_path']); ?>" <?= getimagesize($record['image_path'])[3] ?> alt="article image"> <h2><?= $record['heading'] ?></h2> <span class="author_style">Created by <?= $record['author'] ?> on <time datetime="<?= htmlspecialchars(CMS::styleTime($record['date_added'])) ?>"><?= htmlspecialchars(CMS::styleDate($record['date_added'])) ?></time></span> <p><?= nl2br($record['content']) ?></p> <?php echo (isset($_SESSION['id'])) ? '<a class="editButton" href="edit.php?id= ' . urldecode($record['id']) . '">Record ' . urldecode($record['id']) . '</a>' : null; ?> </article> <?php } $url = 'index.php'; echo $pagination->new_page_links($url); ?> </main> I have a Database Object class An example (not the whole code) - namespace Techshangri; use mysql_xdevapi\Exception; use PDO; use PDOException; class DatabaseObject // The Parent Class: { static protected string $table = ""; // Overridden by the calling class: static protected array $db_columns = []; // Overridden by the calling class: static protected array $objects = []; static protected array $params = []; static protected $searchItem; static protected $searchValue; /* * Pagination static function/method to limit * the number of records per page. This is * useful for tables that contain a lot of * records (data). */ public static function page($perPage, $offset, $loc = 'index'): array { $sql = 'SELECT * FROM ' . static::$table . ' WHERE page=:page ORDER BY date_added DESC LIMIT :perPage OFFSET :blogOffset'; $stmt = Database::pdo()->prepare($sql); // Prepare the query: $stmt->execute(['perPage' => $perPage, 'blogOffset' => $offset, 'page' => $loc]); // Execute the query with the supplied data: return $stmt->fetchAll(PDO::FETCH_ASSOC); } // more code... and I have a Children's class that is more specific: Children's Class (CMS.php) - Example - class CMS extends DatabaseObject { protected static string $table = "cms"; // Table Name: static protected array $db_columns = ['id', 'user_id', 'thumb_path', 'image_path', 'Model', 'ExposureTime', 'Aperture', 'ISO', 'FocalLength', 'author', 'heading', 'content', 'data_updated', 'date_added']; public $id; public $user_id; public $page; public $thumb_path; public $image_path; public $Model; public $ExposureTime; public $Aperture; public $ISO; public $FocalLength; public $author; public $heading; public $content; public $date_updated; public $date_added; /* * Construct the data for the CMS */ public function __construct($args = []) { // $this->user_id = $args['user_id'] ?? null; // $this->author = $args['author'] ?? null; // $this->heading = $args['heading'] ?? null; // $this->content = $args['content'] ?? null; // $this->date_updated = $args['date_updated'] ?? null; // $this->date_added = $args['date_added'] ?? null; // Caution: allows private/protected properties to be set foreach ($args as $k => $v) { if (property_exists($this, $k)) { $v = static::filterwords($v); $this->$k = $v; static::$params[$k] = $v; static::$objects[] = $v; } } } // End of construct method: public static function styleTime($prettyDate): string { try { $dateStylized = new DateTime($prettyDate, new DateTimeZone("America/Detroit")); } catch (Exception $e) { } return $dateStylized->format("Y-m-d H:i:s"); } // more code... I use Active Record Design Pattern as for what I do doesn't get too complex and besides I'm starting to like this pattern. However, if I was doing a really large website I would go more the route of Model-View-Controller pattern. Well, at least I think I would? Anyways, I getting off topic and my point is that after struggling with OOP for awhile, I found out by doing tutorials and looking at examples is to keep your methods and even you classes as short as possible, plus try to have meaning to them that is helpful to you as the coder. The real benefit now is that I can transfer these classes over to other projects (websites) with no problem and that is when I find out if I have written a class that could had been written better. As I sometimes find myself getting a little carried away with a class or putting a method (or even the variables) in the wrong class. I always shoot myself when I do that when come to that realization. 🤣 Everyone codes differently, but that is my logic.

Another thing is PHP OOP is great with inheritance where a lot of that code to put it nicely could be streamline and some of the methods wouldn't even have to be used. Something to look into?

Warning Do not use extract() on untrusted data, like user input (e.g. $_GET, $_FILES). This coming from https://www.php.net/manual/en/function.extract.php

A good thing to have is a good IDE that will point out the common syntax errors and find good resources/tutorials online to help with the logic flow. As for Database Tables I like using PDO and I still go to the following online resource when I get stump or have a brain fart. https://phpdelusions.net/pdo 🤣 I go here and other forums to see if someone before me has had the same problem and if not I will attempt to ask a question while showing my work. I learn over the years not to show too little or way too much code. I find commenting code help not only me but the people helping me trying to solve my problem(s).

From what I am see is that you are doing too much inside methods and even the classes. Keep methods simple as possible such as the following example: public static function page($perPage, $offset, $loc = 'index'): array { $sql = 'SELECT * FROM ' . static::$table . ' WHERE page=:page ORDER BY date_updated DESC LIMIT :perPage OFFSET :blogOffset'; $stmt = Database::pdo()->prepare($sql); // Prepare the query: $stmt->execute(['perPage' => $perPage, 'blogOffset' => $offset, 'page' => $loc]); // Execute the query with the supplied data: return $stmt->fetchAll(PDO::FETCH_ASSOC); } Classes can be inherited from a parent class or even another child class (However, I wouldn't go too deep) There are other ways of doing inheritance as well and some people frown on doing the way I do, but from what I do is small compared to larger development places. class CMS extends DatabaseObject { protected static string $table = "cms"; // Table Name: static protected array $db_columns = ['id', 'user_id', 'thumb_path', 'image_path', 'Model', 'ExposureTime', 'Aperture', 'ISO', 'FocalLength', 'author', 'heading', 'content', 'data_updated', 'date_added']; public $id; public $user_id; public $page; public $thumb_path; public $image_path; public $Model; public $ExposureTime; public $Aperture; public $ISO; public $FocalLength; public $author; public $heading; public $content; public $date_updated; public $date_added; /* * Create a short description of content and place a link button that I call 'more' at the end of the * shorten content. */ #[Pure] public static function intro($content = "", $count = 100): string { return substr($content, 0, $count) . "..."; } I do that with my PDO Database Connection that I call the Grandparent (called Database and I utilize it by doing Database::pdo() ). I go by the the K.I.S.S. (Keep It Simple Stupid) model as I find out that I write less code and can be used over and over again. I find myself (as I sure others do to) when I try to get fancy and write a bunch of code it leads to write more code with the class end up being longer than they should. Granted having a long class is sometimes unavoidable, but even them after you gain more knowledge of PHP can be streamline. I learn something new everyday in PHP coding (and other languages) and sometimes I slap myself why didn't I think of that. 🤣

Actually using Fetch in Vanilla JavaScript is pretty easy to do: (Here's an example) /* Success function utilizing FETCH */ const sendUISuccess = function (result) { //console.log('Result', result); if (result) { d.querySelector('#recaptcha').style.display = "none"; submit.style.display = "none"; notice.style.display = "grid"; notice.textContent = "Email Successfully Sent!"; notice.style.color = "green"; message.style.display = "grid"; //messageSuccess.style.display = "block"; d.querySelectorAll('form > *').forEach(function (a) { a.disabled = true; }); } }; /* If Database Table fails to update data in mysql table */ const sendUIError = function (error) { console.log("Database Table did not load", error); }; const handleSaveErrors = function (response) { if (!response.ok) { throw (response.status + ' : ' + response.statusText); } return response.json(); }; const saveRequest = (sendUrl, succeed, fail) => { fetch(sendUrl, { method: 'POST', // or 'PUT' body: JSON.stringify(sendEmail) }) .then((response) => handleSaveErrors(response)) .then((data) => succeed(data)) .catch((error) => fail(error)); }; though jQuery has jQuery.get() I believe which is the same thing as Fetch in Vanilla JavasScript which might be worth looking into? In my opinion it easier and coding is more logical. I like that you don't have to worry about parsing the data and handling errors is easy to do. In your case you could make a fallback option or tell the other player that the other person is no longer online.

Why don't you just extend the child class? Does it work in the parent class? If it doesn't then there is something wrong with self::$conn You might be initializing the database connection before it is called?

I would suggest using namespaces and an autoloader using composer. A good link in my opinion is this one - https://phpenthusiast.com/blog/how-to-autoload-with-composer and it really help me understand on how to do it. Then you simply can do this : <?php require_once 'assets/config/config.php'; // You still need your trusty configuration file require_once "vendor/autoload.php"; // Autoloader using composer use PhotoTech\CMS; use PhotoTech\Pagination; Here's my Database Class: <?php namespace PhotoTech; use PDO; class Database { private PDO $_connection; // Store the single instance. private static ?Database $_instance = null; // Don't initialize before it is called: // Get an instance of the Database. // @return Database: protected static function getInstance(): Database { if (!self::$_instance) { self::$_instance = new self(); } return self::$_instance; } public static function pdo(): PDO { $db = static::getInstance(); return $db->getConnection(); } // Constructor - Build the PDO Connection: public function __construct() { $db_options = array( /* important! use actual prepared statements (default: emulate prepared statements) */ PDO::ATTR_EMULATE_PREPARES => false /* throw exceptions on errors (default: stay silent) */ , PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION /* fetch associative arrays (default: mixed arrays) */ , PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC ); $this->_connection = new PDO('mysql:host=' . DATABASE_HOST . ';dbname=' . DATABASE_NAME . ';charset=utf8', DATABASE_USERNAME, DATABASE_PASSWORD, $db_options); } // Empty clone magic method to prevent duplication: private function __clone() { } // Get the PDO connection: protected function getConnection(): PDO { return $this->_connection; } } I have been using it for sometime without any problems and to use it I simply do the following class DatabaseObject // Extended by the children class: { static protected string $table = ""; // Overridden by the calling class: static protected array $db_columns = []; // Overridden by the calling class: static protected array $objects = []; static protected array $params = []; static protected $searchItem; static protected $searchValue; /* * There is NO read() method this fetch_all method * basically does the same thing. The query ($sql) * is done in the class the calls this method. */ public static function fetch_by_column_name($sql) { $stmt = Database::pdo()->prepare($sql); // Database::pdo() is the PDO Connection $stmt->execute([ static::$searchItem => static::$searchValue ]); return $stmt->fetch(PDO::FETCH_ASSOC); } // More coding... I should mention I am using PHP 8, so there might be some adjustment that might be needed? I also make comments that are sometime mental notes to me in order to know what I was doing. 😉

Where static really shines is when you using an Active Record Design Pattern (I would assume other patterns are the same way, but this is the only pattern that I have used so far), for example: The Data Object Class class DatabaseObject // Extended by the children class: { static protected string $table = ""; // Overridden by the calling class: static protected array $db_columns = []; // Overridden by the calling class: static protected array $objects = []; static protected array $params = []; static protected $searchItem; static protected $searchValue; // More code.... A Children Class example class CMS extends DatabaseObject { protected static string $table = "cms"; // Table Name: static protected array $db_columns = ['id', 'user_id', 'thumb_path', 'image_path', 'Model', 'ExposureTime', 'Aperture', 'ISO', 'FocalLength', 'author', 'heading', 'content', 'data_updated', 'date_added']; // More Code....

This deals with auto loading classes in php, but it should help you -> https://phpenthusiast.com/blog/how-to-autoload-with-composer or this which is probably more what you are looking for https://phpenthusiast.com/blog/how-to-use-packagist-and-composer A great resource for composer - https://getcomposer.org/ Composer has been around for awhile.

/* if(isset($_GET['page'])) { $page = $_GET['page']; } else { $page = 1; } */ if ( isset($_GET['page']) ) { $current_page = $_GET['page']; } else { $current_page = 1; } $per_page = 20; // $num_per_page = 20; $offset = $per_page * ($current_page - 1) //$sql = "SELECT * FROM people ORDER BY id ASC LIMIT $start_from, $num_per_page"; $sql = 'SELECT * FROM people ORDER BY id ASC LIMIT ' . $per_page . ' OFFSET ' . $offset . '; I think this will work, but I'm just taking an educated guess. You are going to need know the total number of records, so that you don't go pass the total records in your database table using your previous and next links. HTH Helps? Though I do have pagination working on my own website - https://www.phototechguru.com/

I would suggest to find a recent good online PHP tutorial or a recent PHP How-to-code book to get familiar with programming in that language.

The best way to do that is to have a login to the secure area. Here's an example from my website - <?php require_once "../assets/config/config.php"; require_once "../vendor/autoload.php"; use PhotoTech\Resize; use PhotoTech\CMS; use PhotoTech\Login; Login::is_login($_SESSION['last_login']); Login::securityCheck(); and the class that check it: public function __construct($args = []) { static::$searchItem = 'username'; static::$searchValue = htmlspecialchars($args['username']); $this->password = htmlspecialchars($args['hashed_password']); } public static function username() { static::$searchItem = 'id'; static::$searchValue = $_SESSION['id']; $sql = "SELECT username FROM " . static::$table . " WHERE id = :id LIMIT 1"; $user = static::fetch_by_column_name($sql); return $user['username']; } public static function full_name(): string { static::$searchItem = 'id'; static::$searchValue = $_SESSION['id']; $sql = "SELECT first_name, last_name FROM " . static::$table . " WHERE id =:id LIMIT 1"; $user = static::fetch_by_column_name($sql); return $user['first_name'] . " " . $user['last_name']; } public static function securityCheck() { static::$searchItem = "id"; static::$searchValue = $_SESSION['id']; $sql = "SELECT security FROM " . static::$table . " WHERE id=:id LIMIT 1"; $result = static::fetch_by_column_name($sql); /* * Only Sysop privileges are allowed. */ if ($result['security'] !== 'sysop') { header("Location: ../game.php"); exit(); } } // more code..... It's my own personal website and I'm no security "expert", but I feel it pretty secure in what I do. Something like that will keep people from accessing those pages.

$file_name = $_FILES['gambar']['name']; // Original File Name: $file_size = $_FILES['gambar']['size']; $file_tmp = $_FILES['gambar']['tmp_name']; // Temporary file for the directory: $file_type = $_FILES['gambar']['type']; $file_ext = strtolower(pathinfo($_FILES['gambar']['name'], PATHINFO_EXTENSION)); /* * Set the path to the correct folder */ $dir_path = 'folder/pda-semakan/gambar/'; /* * Create unique name for file. */ $new_file_name = $dir_path . 'file-example-' . time() . '.' . $file_ext; move_uploaded_file($file_tmp, $new_file_name); I didn't test this out, but you would do something like the above. Note $new_file_name would also store the path in the database table, so if you just want the just file then just out the $dir_path after saving the file to the directory.
