Question

Creating a rating system and the info is not being transmitted through my $_GET variable. The code is below

    if (isset($_GET['item'], $_GET['rating'])){
echo 'Works!';
}

The variable is being entered in this code below

  <?php echo number_format( 
        $article['rating'],1); ?>
        <div class = "rate">
            Rate:
            <?php
            for ($x =1; $x<= $maximum_rating; $x++){
            ?>
                <a href="prestige.php?item=<?php echo $article['id']; ?>&rating=<?php echo $x;?>">
                <?php echo $x; ?></a>
            <?php
            }
            ?>

I am fairly new to programming so any ideas or tips would be greatly appreciated.

Answer 1

There are a couple of things you should do.

1.
Instead of

prestige.php?item=<?php echo $article['id']; ?>&rating=<?php echo $x;?>

Use

prestige.php?<?= http_build_query(array('item' => $article['id'], 'rating' => $x), '&amp;') ?>

This will escape the parameters. Vars $article['id'] and $x could contain characters that break the HTML or URL.

2.
Look at the Net tab in your Firebug/Chrome dev toolbar. Are there any redirects? What headers are sent?

Also look at the address bar to see if prestige.php really is loaded with the GET parameters.

3.
Use a debug tool like XDebug to step through your code. You might have some code that resets the $_GET vars. Personally I use the IDE PHPed, but it’s kinda expensive.
