[How to remove sidebar from post page]

I would studied up on using  CSS Grids, CSS Flexbox and media queries for responsive that way you can control the any page layout.

[<picture> tag not appearing photo in live server]

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.

[session data help]

I'd also point out that you aren't using prepared statements. I'd recommend learning PDO over mysqli. Additionally, you seem to rely heavily on sessions when ideally, only the user's ID should be stored in them and maybe a token.

[TypeError: arrayOfObjects is not iterable]

// Import the arrayOfObjects from the data module.
const arrayOfObjects = require("./data");

// Iterate through each object in the arrayOfObjects.
for (const obj of arrayOfObjects) {
  // Log the id and name properties of the current object to the console.
  console.log(`ID: ${obj.id}, Name: ${obj.name}`);
}

For the data module that contains the array of objects:

// Define an array of objects with properties id and name.
const arrayOfObjects = [
  { "id": 1, "name": "bla bla" },       // Object with id 1 and name 'bla bla'
  { "id": 2, "name": "bla bla bla" }   // Object with id 2 and name 'bla bla bla'
];

// Export the arrayOfObjects so it can be imported and used in other modules.
module.exports = arrayOfObjects;

If you are `editing` the data anywhere else and that data isn't clean then you will have to look at that code as well. I hope I'm making sense.

[Login and password hash]

3 minutes ago, LeonLatex said:

@mac_gyver, If you look in bottom of my first posting you find my login form. I dont have a registration form yet because so early in the development process i manually put the testing user accounts in mysql manually. I dont have time to use more time on this now, so i will start develop another system, and this time with email confirmation and a confirmation code. Is less use of time to put a new one together than looking for errors in this login system. I dont think there is only one error. The system has going through many changes through the last year, so it's time to let the old one rest. Any way, thanks for using time for trying to help 😃

You don't need a registration form/page as all you have to do is hash your password that you want to use. That's what I do when I develop my website(s).

It might not help you with this project, but it'll give you a better understanding on how to use it.

[Problem sending formdata to php using fetch]

You need to do something like this ->

        // Add an event listener to the edit form's submit event
        editForm.addEventListener("submit", async function (event) {
            // Prevent the default form submit behavior
            event.preventDefault();

            // Create a FormData object from the edit form
            const formData = new FormData(editForm);
            //console.log("form data", formData);
            // Send a POST request to the edit_update_blog.php endpoint with the form data
            const response = await fetch("edit_update_blog.php", {
                method: "POST",
                body: formData,
            });

            // Check if the request was successful
            if (response.ok) {
                const result = await response.json();
                console.log(result);
                // If the response has a "success" property and its value is true, clear the form
                if (result.success) {
                    resultInput.value = '';          // Clear the current value of the search input field
                    resultInput.placeholder = "New Search"; // Set the placeholder to `New Search`
                    image_for_edit_record.src = "";
                    image_for_edit_record.alt = "";
                    editForm.reset(); // Resetting the edit form
                    searchForm.reset(); // Resetting the search form

                    // Reset select box to default (first) option
                    const selectBox = document.querySelector('select[name="heading"]');
                    selectBox.selectedIndex = 0;
                }

            } else {
                console.error(
                    "Error submitting the form:",
                    response.status,
                    response.statusText
                );
                // Handle error response
            }
        });

also using `console.log` helps in debugging, plus your `sql_connection.php` is expecting back json data back.

[How to view raw php fewtchAll() output]

19 minutes ago, Adamhumbug said:

Hi All,

As i am trying to learn more and more i wanted to know if there was a way of looking at a raw fetchall() when running functions in php.

I have a function call on my page which is set to var_dump the return.

Is it possible to show the whole array on that page?

Sure, I just do something like this

echo "<pre>" . print_r($results, 1) . "</pre>";

It's a great way to debug also.

[WHy does removing eventListener cause an error?]

/* ----- Upload File / Image ----- */
function uploadFile(uid) {
    const url = 'process.php';
    const form = document.querySelector('form');
    
    form.onsubmit = function(e) {
        e.preventDefault();

        const files = document.querySelector('[type=file]').files;
        const formData = new FormData();

        for (let i = 0; i < files.length; i++) {
            let file = files[i];
            formData.append('files[]', file);
            formData.append('uploadid', uid);
        }

        fetch(url, {
            method: 'POST',
            body: formData
        }).then(response => {
            return response.text();
        }).then(data => {
            console.log(data);
        });
    };
    
    return;
}

Instead of using the addEventListener method for the form submission, you can directly bind the function to the form's onsubmit?

Personally, if I were writing a chess game I would use JavaScript and Canvas not PHP for the main coding part of the game.

[Need help Securing PHP PDO files for users to edit their own submission]

I just wanted to add that when I took a course in web design one of the things to do is keep the form simple as possible. I'm assuming all that data is coming from a form? If that case I would simplify it down a bit as most visitors will leave that website if they see a HTML form that l large.

An example of what I'm talking about.

[php class autoload question]

My suggestion is to use composer https://getcomposer.org/ as it will save you a lot a headaches and you don't have to reinvent the wheel.

Then you can just do something like the following ->

<?php
// Include the configuration file and autoload file from the composer.
require_once __DIR__ . '/../config/config.php';
require_once "vendor/autoload.php";

// Import the ErrorHandler and Database classes from the PhotoTech namespace.
use brainwave\{
    ErrorHandler,
    Database,
    Links,
    ImageContentManager,
    LoginRepository as Login
};

// Instantiate the ErrorHandler class
$errorHandler = new ErrorHandler();

// Set the exception handler to use the handleException method from the ErrorHandler instance
set_exception_handler([$errorHandler, 'handleException']);

// Create a new instance of the Database class
$database = new Database();
// Create a PDO instance using the Database class's method
$pdo = $database->createPDO();

$login = new Login($pdo);
if ($login->check_login_token()) {
    header('location: dashboard.php');
    exit();
}

$cms = new ImageContentManager($pdo);

a sample class ->

<?php
// ErrorHandler.php
namespace brainwave;

use PDOException;
use Throwable;
use JsonException;

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());
        }
    }
}

I would also check out namespace for PHP classes.

[php mysql image upload issue]

1 hour ago, PNewCode said:

I figured it out. I was trying to add stuff to the wrong if statement. Instead I just changed the following, and now it works

 

 if (isset($_POST["submit"]))
 {
$pname = "";
	 if(!empty($_FILES["file"]["name"])){
     $allowed_img = array('gif', 'png', 'jpg', 'jpeg');

 

This is taken from my website project ->

 

$file_ext = strtolower(pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION));
$extensions = array("jpeg", "jpg", "png");

if (in_array($file_ext, $extensions, true) === false) {
    $errors[] = "extension not allowed, please choose a JPEG or PNG file.";
}

    /*
     * If no errors save ALL the information to the
     * database table.
     */
    if (empty($errors) === true) {
        // Code that does it....
    }

I know my variable naming isn't exact, but it should give you a basic way in doing it.

I have the GitHub repository -> https://github.com/Strider64/brain-wave-blitz/blob/master/create_cms.php feel free to look around.

[Read data from multi-array?]

A simple way in my opinion would to do something like the following.

fetch('https://example.com/data-endpoint') // replace with your actual URL
  .then(response => {
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    return response.json(); // this returns a promise
  })
  .then(data => {
    console.log(data); // this will log the whole data to the console

    // you can access any data point like this:
    console.log(data.newOffers); // logs: null
    console.log(data.usedOffers[0].price); // logs: 49.23

    // if you want to loop through all the usedOffers you can do something like this:
    data.usedOffers.forEach(offer => {
      console.log(`Offer ID: ${offer.id}`);
      console.log(`Price: ${offer.price}`);
      console.log(`Delivery Rate: ${offer.deliveryRate}`);
      // ... and so on for other properties
    });
  })
  .catch(e => {
    console.log('There was a problem with the fetch operation: ' + e.message);
  });

I'm half asleep that from the JavaScript side, but I find JavaScript more flexible than PHP and easier.

This could be done in JavaScript or even pulling from a Database Table. Like I said it's an old script that I modernized it a little.

[Do not echo empty field from Mysql]

2 hours ago, Barand said:

If you want to hide them, why include them in the query in the first place?

There are times that it needs to be done, for example if a game has multiple choices and there are only 2 possible answers.

This is a JavaScript pulling data from a database table using fetch ->

        // This line sets the text content of the button to the corresponding answer (ans1, ans2, ans3, ans4)
        // with a "📷" character at the beginning.
        button.textContent = `📷 ${[ans1, ans2, ans3, ans4][index]}` || "";

        // If there's no corresponding answer, the button is disabled (its pointer events are set to "none").
        // Otherwise, the button is enabled (its pointer events are set to "auto").
        if (![ans1, ans2, ans3, ans4][index]) {
            button.style.pointerEvents = "none";
        } else {
            button.style.pointerEvents = "auto";
        }

Though I have of admit most of the time is a waste of time coding for empty fields.

[Why does window.load function triggers "click" event of elements?]

I have been developing an online trivia game for years now and I have finally wrapped this around my head. (Well, at least I think 😂 )

HTML

                    <div id="answers">
                        <button class="buttonStyle" id="ans1"></button>
                        <button class="buttonStyle" id="ans2"></button>
                        <button class="buttonStyle" id="ans3"></button>
                        <button class="buttonStyle" id="ans4"></button>
                    </div>

JavaScript

// Function to handle the event when an answer is selected.
const pickAnswer = (answerIndex) => {
    return () => {
        choice = answerIndex;
        checkAnswer();
        // Only show the next button if the next question exists
        if (index < triviaData.length - 1) {
            nextButton.style.display = "block"; // show the next button after an answer is chosen
        }
    };
};

// The `startGame` function takes an object as an argument with properties: ans1, ans2, ans3, ans4, id, question.
// These properties represent the answers to the current question, the question's id, and the question itself, respectively.
const startGame = ({ ans1, ans2, ans3, ans4, id, question }) => {
    // This line sets the id of the current question to the "data-record" attribute of the element with id "currentQuestion".
    document.querySelector("#currentQuestion").setAttribute("data-record", id);

    // This line sets the display number of the current question (index + 1) to the text content of the element with id "currentQuestion".
    document.querySelector("#currentQuestion").textContent = (index + 1).toString();

    // This line sets the text content of the element with id "question" to the question itself.
    document.querySelector("#question").textContent = question;

    // This loop iterates over each of the answer buttons.
    answerButtons.forEach((button, index) => {
        // This line checks if there was a previous "pickAnswer" event listener attached to the button,
        // and if so, removes it.
        const previousPickAnswer = button.__pickAnswer__;
        if (previousPickAnswer) {
            button.removeEventListener("click", previousPickAnswer);
        }

        // This line creates a new "pickAnswer" event listener, and attaches it to the button.
        const newPickAnswer = pickAnswer(index + 1);
        button.addEventListener("click", newPickAnswer, false);
        button.__pickAnswer__ = newPickAnswer;

        // This line sets the text content of the button to the corresponding answer (ans1, ans2, ans3, ans4)
        // with a "📷" character at the beginning.
        button.textContent = `📷 ${[ans1, ans2, ans3, ans4][index]}` || "";

        // If there's no corresponding answer, the button is disabled (its pointer events are set to "none").
        // Otherwise, the button is enabled (its pointer events are set to "auto").
        if (![ans1, ans2, ans3, ans4][index]) {
            button.style.pointerEvents = "none";
        } else {
            button.style.pointerEvents = "auto";
        }
    });
};

I comment the script out and I think it's self-explanatory. OK, I'm tired as this is the latest I have stayed up. 🤣

[what is the best approach ? Use Classes, use functions or something else ?]

I use classes as I like mobility of the code going from one website to the another is easier for me. I don't use Frameworks or Libraries. I like using Vanilla JavaScript as I don't have to think about having a library. I find out that I really don't write that much more code just using good old plain JavaScript.

 

Here's a JavaScript Online Trivia game that I updating. I am using CodePen to do a mockup first of it -> https://codepen.io/Strider64/pen/NWEpZdj

Like already stated everyone has their own coding style and I am sure you will find yours.

[Parse error: syntax error,]

Maybe something like this for variable naming and form field names?

$fullName = filter_input(INPUT_POST, 'fullName');
$phone = filter_input(INPUT_POST, 'phone');
$email = filter_input(INPUT_POST, 'email');
$propertyType = filter_input(INPUT_POST, 'propertyType');
$address = filter_input(INPUT_POST, 'address');
$priceRange = filter_input(INPUT_POST, 'priceRange');
$bedrooms = filter_input(INPUT_POST, 'bedrooms'); 
$bathrooms = filter_input(INPUT_POST, 'bathrooms'); 
$preApproved = filter_input(INPUT_POST, 'preApproved'); 

if ($preApproved === "yes")  {
    echo $preApprovalAmount;
}

$parkingType = filter_input(INPUT_POST, 'parkingType'); 
$buyingTimeline = filter_input(INPUT_POST, 'buyingTimeline'); 
$exploreZips = filter_input(INPUT_POST, 'exploreZips'); 
$dreamHomeWish = filter_input(INPUT_POST, 'dreamHomeWish');

 

[Php mysql user delete option. This one is tricky]

You're going to need to setup some kind of security check - Here's a example

 

function check_security($id) {
    // Example of PHP Connection
    $db = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');
    
    $sql = "SELECT security FROM user_table WHERE id=:id LIMIT 1";
    $stmt = $db->prepare($sql);
    
    // Bind the named parameter :id to the value $id
    $stmt->bindParam(':id', $id, PDO::PARAM_INT);
    
    $stmt->execute();
    
    // Fetch the result as an associative array
    $result = $stmt->fetch(PDO::FETCH_ASSOC);

    if ($result && $result['security'] === 'admin') {
        return true;
    }

    return false;
}

then simply

// Check if the user has admin security by calling the check_security function
if (check_security($id)) {
    // If the function returns true, echo out an HTML anchor tag that leads to delete-post.php
    // The id of the row to delete is passed in the query string of the URL
    // Inside the anchor tag is a button with the class btn3 and the text DELETE
    echo '<a href="delete-post.php?id='.$row['id'].'"><button class="btn3">DELETE</button></a>';
}

You will still need to check the delete-post.php in order to stop some one from directly accessing that file. This is just a quick example and you can even do that for the original user - just check to see if the user's id for the post matches the original poster's id. Just setup an addition column like user_id in the database table that contains the posts (if you haven't already done so).

[How do promises program flow work in javascript?]

"await" is great if you need have all the data before you moving on especially good when developing a game.

// Fetch the First ID
const fetchFirstId = async () => {
    try {
        // fetch the data from the server
        const response = await fetch('get-first-id.php', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json'
            },
            body: JSON.stringify({resetScore: false})
        });

        // parse the response as JSON
        const data = await response.json();
        id = data.first_id; // Grab the First ID the DB Table
        //console.log(id);
        await changeImageSource(data.image);
        await fetchQuestion();
        await fetchWord(); // fetch the answers
        //await fetchImage();
    } catch (error) {
        console.error(error);
    }
};

 

[PHP brings back all the results but I only want one record, when typed in query]

You can do a full text content search on a `content` field, but the main thing is you have to search a column in order to find what you are looking for.

This is done in PDO, but gives an example on what I'm trying to say -

 

 // Extract the search term and heading from the request, if they exist.
    $searchTerm = isset($request['searchTerm']) ? $request['searchTerm'] : null;
    $heading = isset($request['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 gallery ADD FULLTEXT(content);
    if($searchTerm !== null) {
        $sql = "SELECT * FROM gallery 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 gallery 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);
