  1. If you are trying to enter data, but you don't know exactly how many fields (columns) you are going to be saving to the table then you could do something like the following. Though would still need the correct table's column names and the corresponding data that goes with it. Here's an example -> function create(array $data, $pdo, $table) { try { /* Initialize an array */ $attribute_pairs = []; /* * Set up the query using prepared states with the values of the array matching * the corresponding keys in the array * and the array keys being the prepared named placeholders. */ $sql = 'INSERT INTO ' . $table . ' (' . implode(", ", array_keys($data)) . ')'; $sql .= ' VALUES ( :' . implode(', :', array_keys($data)) . ')'; /* * Prepare the Database Table: */ $stmt = $pdo->prepare($sql); /* * Grab the corresponding values in order to * insert them into the table when the script * is executed. */ foreach ($data as $key => $value) { if($key === 'id') { continue; } // Don't include the id: $attribute_pairs[] = $value; // Assign it to an array: } return $stmt->execute($attribute_pairs); // Execute and send boolean true: } catch (PDOException $e) { if ($e->errorInfo[1] === 1062) { return false; } throw $e; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; // Not for a production server: } return true; }
  2. Here's a countdown clock that I did years ago, but I recently updated it a couple of months ago. countdown.js file "use strict"; /** * Calculates the time remaining until a specified end time. * @param {string} endtime - The end time in a format parseable by Date.parse. * @returns {object} An object containing the total milliseconds and the breakdown in days, hours, minutes, and seconds. */ const getTimeRemaining = (endtime) => { const total = Date.parse(endtime) - Date.now(); // Calculate the difference in milliseconds from now to the end time return { total, days: Math.floor(total / (1000 * 60 * 60 * 24)), // Convert milliseconds to days hours: Math.floor((total / (1000 * 60 * 60)) % 24), // Convert milliseconds to hours, modulo 24 minutes: Math.floor((total / 1000 / 60) % 60), // Convert milliseconds to minutes, modulo 60 seconds: Math.floor((total / 1000) % 60) // Convert milliseconds to seconds, modulo 60 }; }; /** * Initializes a countdown clock on the webpage. * @param {string} id - The ID suffix of the countdown clock container. * @param {Date} endtime - The countdown end time. */ const initializeClock = (id, endtime) => { const clock = document.getElementById(`display_clock${id}`); // Access the clock element by ID if (!clock) { console.error(`Clock with id 'display_clock${id}' not found.`); return; // Exit if no element is found } // Map each time unit to its corresponding DOM element within the clock container const fields = ['days', 'hours', 'minutes', 'seconds'].map(field => clock.querySelector(`.${field}`) ); if (fields.some(element => element === null)) { // Check if any elements are missing console.error('One or more clock elements not found:', fields); return; // Exit if missing elements are found } // Updates the countdown clock display every second const updateClock = () => { const { total, days, hours, minutes, seconds } = getTimeRemaining(endtime); // Update each field in the DOM with the new time [days, hours, minutes, seconds].forEach((val, i) => { fields[i].textContent = String(val).padStart(2, '0'); // Format with leading zeros }); if (total <= 0) { clock.textContent = "Contest Finished, entry time expired"; clearInterval(timeInterval); // Stop the timer if the countdown is complete } }; updateClock(); const timeInterval = setInterval(updateClock, 1000); // Set the timer to update every second }; /** * Fetches the countdown data and initializes the clock using that data. */ const fetchRoutine = () => { fetch('data.json') // Fetch the countdown data from a local JSON file .then(response => response.json()) .then(data => { document.getElementById("countdown_date").textContent = data.date_format; // Set the formatted date document.getElementById("display_title").textContent = data.title; // Set the event title initializeClock(1, new Date(Date.parse(data.time_left))); // Initialize the clock with the fetched data }) .catch(error => { console.error('Fetch error:', error); // Log any errors during fetch }); }; // Ensure all DOM content is loaded before executing the fetch routine. document.addEventListener('DOMContentLoaded', fetchRoutine); it pulls in data from data.json file { "time_left": "2024-08-27T11:59:59-04:00", "date_format": "Tuesday - August 28, 2024", "title": "Countdown to " } here is the HTML file: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Countdown Clock</title> <link rel="stylesheet" href="reset.css"> <link rel="stylesheet" href="countdown.css"> </head> <body> <div class="info"> <h1 id="display_title"></h1> <h2 id="countdown_date"></h2> </div> <div id="display_clock1"> <figure class="box"> <div class="days"></div> <figcaption>Days</figcaption> </figure> <figure class="box"> <div class="hours"></div> <figcaption>Hours</figcaption> </figure> <figure class="box"> <div class="minutes"></div> <figcaption>Minutes</figcaption> </figure> <figure class="box"> <div class="seconds"></div> <figcaption>Seconds</figcaption> </figure> </div> <script src="countdown.js"></script> </body> </html> and even the css file countdown.css *{ -webkit-box-sizing: border-box; box-sizing: border-box; } div.info { display: block; width: 100%; max-width: 300px; height: auto; text-align: center; padding: 2px; margin: 10px auto; } div.info::after { content: ''; display: block; clear: both; } h1 { font-family: "Palatino Linotype", "Book Antiqua", Palatino, serif; font-size: 1.2em; line-height: 1.5; } h2 { font-family: Arial, Helvetica, sans-serif; font-size: 1.0em; font-style: italic; font-weight: 300; } div#display_clock1 { display: block; width: 100%; max-width: 190px; height: auto; margin: 5px auto; background-color: pink; } div#display_clock1 figure.box { float: left; display: block; width: 100%; max-width: 40px; height: 70px; color: #fff; text-align: center; padding: 0; margin-left: 5px; } div#display_clock1 figure.box div { background-color: #2e2e2e; height: 50px; line-height: 50px; } div#display_clock1 figure.box figcaption { font-family: Arial, Helvetica, sans-serif; font-size: 0.6em; line-height: 20px; font-weight: bold; color: #000; } It's a simple countdown clock, but can be modify to enhance. I did check it out that it still runs properly. Fetching the clock can be modify to add even more countdown counters by the `id` in this example there is only 1.
  3. Ever since AI I have seen tech forums like this one become very quiet which isn't surprising.
  4. I didn't create a Model, but a trait though maybe it will give you some ideas? <?php // NavigationMenuTrait.php namespace clearwebconcepts; use function htmlspecialchars; use function hash_equals; trait NavigationMenuTrait { public function regular_navigation(): void { $navItems = [ 'Home' => 'index.php', 'About' => 'about.php', 'Puzzle' => 'puzzle.php', 'Portfolio' => 'portfolio.php', 'Contact' => 'contact.php' ]; // Check if the user is logged in $isLoggedIn = isset($_COOKIE['login_token']) && isset($_SESSION['login_token']) && hash_equals($_SESSION['login_token'], $_COOKIE['login_token']); if ($isLoggedIn) { unset($navItems['Home']); // Remove 'Home' from the navigation menu // Add 'Dashboard' to the start of the navigation menu $navItems = array('Dashboard' => 'dashboard.php') + $navItems; } else { $navItems['Login'] = 'login.php'; // Add 'Login' to the navigation menu } $navLinks = []; foreach ($navItems as $title => $path) { $href = $this->generateHref($path); $safeTitle = htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); $navLinks[] = "<a href=\"{$href}\">{$safeTitle}</a>"; } // Check if the user is logged in if ($isLoggedIn) { $navLinks[] = '<a href="logout.php">Logout</a>'; // Add 'Logout' to the end of the navigation menu } echo implode('', $navLinks); } public function showAdminNavigation(): void { $protocol = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ? 'https://' : 'http://'; $host = $_SERVER['HTTP_HOST']; // Define your base path here $base_path = ($host === 'localhost:8888') ? '/clearwebconcepts' : ''; $base_url = $protocol . $host . $base_path; $adminItems = [ 'Create Entry' => $base_url . '/create_cms.php', 'Edit Entry' => $base_url . '/edit_cms.php', 'Add to Portfolio' => $base_url . '/new_portfolio.php', 'Edit Portfolio Page' => $base_url . '/edit_portfolio.php', 'Add Jigsaw' => $base_url . '/add_to_puzzle.php', 'Edit Jigsaw' => $base_url . '/edit_puzzle.php', 'Service Form' => $base_url . '/service_form.php' ]; echo '<div class="admin-navigation">'; foreach ($adminItems as $adminTitle => $adminPath) { $adminSafeTitle = htmlspecialchars($adminTitle, ENT_QUOTES, 'UTF-8'); echo "<a href=\"{$adminPath}\">{$adminSafeTitle}</a>"; } echo '</div>'; } private function generateHref(string $path): string { $protocol = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ? 'https://' : 'http://'; $host = $_SERVER['HTTP_HOST']; // Define your base path here $base_path = ($host === 'localhost:8888') ? '/clearwebconcepts' : ''; $base_url = $protocol . $host . $base_path; // Build the URL first, then validate it $url = $base_url . '/' . $path; $sanitized_url = filter_var($url, FILTER_SANITIZE_URL); $valid_url = filter_var($sanitized_url, FILTER_VALIDATE_URL); if ($valid_url === false) { die('Invalid URL'); } return $valid_url; } }
  5. I create a simple error log for my own use and it comes in handy in debugging without the user knowing about it. I even created a simple error handler to sort the errors. class ErrorHandler implements ErrorHandlerInterface { public function handleException(Throwable $e): void { if ($e instanceof PDOException) { error_log('PDO Error: ' . $e->getMessage()); } elseif ($e instanceof JsonException) { error_log('JSON Error: ' . $e->getMessage()); } else { error_log('General Error: ' . $e->getMessage()); } } } and in my configuration file // Set the path for the error log file ini_set('error_log', __DIR__ . '/error_log/error_log_file.log'); this is the most import. part errors isn't seen by the public.
  6. Here's my query -> $sql = 'SELECT * FROM '. $this->table . ' WHERE page =:page AND category =:category ORDER BY id DESC, date_added DESC LIMIT :perPage OFFSET :blogOffset'; it might help?
  7. That sure seems like a strange way in doing pagination. In my opinion the data should be come from a database table and broken down to something like the following -> // Grab the current page the user is on if (isset($_GET['page']) && !empty($_GET['page'])) { $current_page = urldecode($_GET['page']); } else { $current_page = 1; } $per_page = 2; // Total number of records to be displayed: // Grab Total Pages $total_pages = $cms->total_pages($total_count, $per_page); /* Grab the offset (page) location from using the offset method */ /* $per_page * ($current_page - 1) */ $offset = $cms->offset($per_page, $current_page); // Figure out the Links that you want the display to look like $links = new Links($current_page, $per_page, $total_count, $category); // Finally grab the records that are actually going to be displayed on the page $records = $cms->page($per_page, $offset, 'cms', $category); that way all you have to do is format. the HTML using CSS -> <main class="main_container" itemprop="mainContentOfPage"> <?php foreach ($records as $record) { $imagePath = htmlspecialchars($record['image_path'], ENT_QUOTES, 'UTF-8'); $heading = htmlspecialchars($record['heading'], ENT_QUOTES, 'UTF-8'); $content = htmlspecialchars($record['content'], ENT_QUOTES, 'UTF-8'); echo '<div class="image-header">'; echo '<img src="' . $imagePath . '" title="' . $heading . '" alt="' . $heading . '">'; echo '</div>'; echo '<h1>' . $heading . '</h1>'; echo '<p>' . nl2br($content) . '</p>'; echo '<br><hr><br>'; } ?> </main> The above is just an example, but if you breakdown the HTML/Code in smaller sections it's easier to read & debug. There are a lot of good pagination tutorials online.
  8. First get the PDO connection out of the function as that will cause you nothing but headaches. Here's an example of a generic PDO connection -> <?php $host = ''; // or your database host $db = 'your_database_name'; $user = 'your_database_username'; $pass = 'your_database_password'; $charset = 'utf8mb4'; $dsn = "mysql:host=$host;dbname=$db;charset=$charset"; $options = [ PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC, PDO::ATTR_EMULATE_PREPARES => false, ]; try { $pdo = new PDO($dsn, $user, $pass, $options); // Use $pdo to perform database operations } catch (\PDOException $e) { throw new \PDOException($e->getMessage(), (int)$e->getCode()); } ?> I would put this in a configuration file maybe name it config.php file? My example would entail explaining OOP, so maybe someone else will do a better example for you. But here is how I do it -> $sql = "SELECT id, password FROM admins WHERE username =:username LIMIT 1"; $user = $this->retrieve_credentials($sql, $username); if ($user && password_verify($password, $user['password'])) { session_regenerate_id(); // prevent session fixation attacks $_SESSION['user_id'] = $user['id']; return true; } return false; and little more code protected function retrieve_credentials(string $sql, string $username): ?array { $stmt = $this->pdo->prepare($sql); $stmt->execute(['username' => $username]); $result = $stmt->fetch(PDO::FETCH_ASSOC); return $result !== false ? $result : null; }
  9. Studying design patterns such as MVC (Model-View-Controller) and Active Record Design has enhanced my understanding of Object-Oriented Programming (OOP). Although many prefer Model-View-Controller, I found Active Record Design more helpful in solidifying my grasp of OOP. One constant with OOP is that there's always something new to learn, and there's always someone with a deeper understanding of it. I believe that beginners often find the structure of Object-Oriented Programming (OOP) challenging. Here's an example from some code on my website to illustrate this. -> // Display Record(s) by Pagination public function page($perPage, $offset, $page = "index", $category = "general"): array { $sql = 'SELECT * FROM '. $this->table . ' WHERE page =:page AND category =:category ORDER BY id ASC, date_added DESC LIMIT :perPage OFFSET :blogOffset'; $stmt = $this->pdo->prepare($sql); // Prepare the query: $stmt->execute(['page' => $page, 'perPage' => $perPage, 'category' => $category, 'blogOffset' => $offset]); // Execute the query with the supplied data: return $stmt->fetchAll(PDO::FETCH_ASSOC); } Initially, I would mix up my code by writing `$sql` and `$this->sql`, which made things confusing for me. However, everyone has their unique journey in learning Object-Oriented Programming (OOP). By coding in this manner, I'm able to more clearly identify key OOP components, such as recognizing `$this->pdo` and understanding that `$stmt->fetchAll(PDO::FETCH_ASSOC)` is an example of object-oriented code.
  10. My approach would be to divide the content into three files, although it's feasible to combine everything into a single file. Nonetheless, I'd still make an effort to keep the code and HTML distinct and separate as much as possible. Client's search page - example clients.php (form to search) JavaScript file - example clients.js PHP search results file - example client_results.php Here's an example of what I'm trying to express: My HTML form (edit_cms.php): <div class="search-form-container"> <form id="searchForm"> <div class="input-group"> <label for="heading">Heading:</label> <select class="select-css" id="heading" name="heading"> <option value="" disabled selected>Select Heading</option> <?php foreach ($records as $record) { echo '<option value="' . $record['heading'] . '">' . $record['heading'] . '</option>'; } ?> </select> </div> <div class="input-group"> <label for="searchTerm">Search Product Content:</label> <input type="text" placeholder="Search Content" id="searchTerm" class="input-field" autofocus required> </div> <button class="search_button" type="submit">Search</button> </form> </div> A little bit of my JavaScript code (edit_cms.js): async function displayRecord(searchTerm = null, selectedHeading = null) { const requestData = {}; if(searchTerm !== null) requestData.searchTerm = searchTerm; if(selectedHeading !== null) requestData.heading = selectedHeading; try { const response = await fetch("search_cms_records.php", { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify(requestData), }); const data = await response.json(); console.log(data); // Add this line if (data.message) { resultInput.value = ''; resultInput.placeholder = data.message; } else if (data.error) { console.error(data.error); } else { const row = data[0]; console.log(row); idInput.value = row.id; image_for_edit_record.src = row.thumb_path; image_for_edit_record.alt = row.heading; category.value = row.category; category.textContent = `${row.category.charAt(0).toUpperCase()}${row.category.slice(1)}`; heading.value = row.heading; content.value = row.content; resizeTextarea(content); } } catch (error) { console.error("Error:", error); } } and my PHP file with a little bit of the code that gets the results (search_cms_records.php): // Get the request body and decode it as JSON. $request = json_decode(file_get_contents('php://input'), true); // Extract the search term and heading from the request, if they exist. $searchTerm = $request['searchTerm'] ?? null; $heading = $request['heading'] ?? null; // If a search term was provided, use a full-text search on the 'content' field. // Before this can work, you'll need to make sure your content column is indexed for full-text searching. // You can do this with the following SQL command: // Example: // ALTER TABLE cms ADD FULLTEXT(content); if($searchTerm !== null) { $sql = "SELECT * FROM cms WHERE MATCH(content) AGAINST(:searchTerm IN NATURAL LANGUAGE MODE) LIMIT 1"; $stmt = $pdo->prepare($sql); $stmt->bindValue(':searchTerm', $searchTerm); // If a heading was provided, search for exact matches on the 'heading' field. } else if($heading !== null) { $sql = "SELECT * FROM cms WHERE heading = :heading LIMIT 1"; $stmt = $pdo->prepare($sql); $stmt->bindValue(':heading', $heading); // If neither a search term nor a heading was provided, throw an exception. } else { throw new Exception("No valid search term or heading provided"); } // Execute the prepared statement. $stmt->execute(); // Fetch the results and handle them as needed. $results = $stmt->fetchAll(PDO::FETCH_ASSOC); // If results were found, return them to the client as JSON. if ($results) { echo json_encode($results); } else { echo json_encode(['message' => 'No results found.']); } My argument is that debugging becomes simpler when most of the code is organized and separated as much as possible within its respective programming language.
  11. I personally find it better to have the configuration file outside the root directory require_once __DIR__ . '/../config/config.php'; // Goes one up from the root / directory
  12. Instead of using `if` statements you should be using `functions`, plus PHP has a great way of doing pagination (The following is just an example of what I'm talking about) -> // Display Record(s) by Pagination public function page($perPage, $offset, $page = "index", $category = "general"): array { $sql = 'SELECT * FROM '. $this->table . ' WHERE page =:page AND category =:category ORDER BY id ASC, date_added DESC LIMIT :perPage OFFSET :blogOffset'; $stmt = $this->pdo->prepare($sql); // Prepare the query: $stmt->execute(['page' => $page, 'perPage' => $perPage, 'category' => $category, 'blogOffset' => $offset]); // Execute the query with the supplied data: return $stmt->fetchAll(PDO::FETCH_ASSOC); } I would look into pagination tutorials as that will save you a lot headaches.
  13. I would studied up on using CSS Grids, CSS Flexbox and media queries for responsive that way you can control the any page layout.
  14. You might want to check that your CSS is the same on both servers and that is correct. For example if you have `display:none;` the image won't show. Ensure that the file permissions for the image are set correctly. The web server should have read access to the image file. If you're using an Apache web server, check your .htaccess file and server configuration for any rules that might be affecting image loading.
