Question

So I have some data in MySQL being shown on my PHP page inside a table. I’ve set it up so that each page only displays 3 results each (temporary until it goes live, then it will be more). Everything works fine and it displays those 3 results on each page just fine.

What I want to do is be able to change the amount of results on each page right from the main PHP page. I can change the amount shown on that one page, but as soon as I go to page 2, it resets to 3 results. How can I remember the number stored in the variable, and display it on every page? I tried using SESSIONS, but I couldn’t get it to work. I’m still a beginner btw.

$item = $_REQUEST['item'];
if(isset($_REQUEST['item'])){
    $limit=$item;
}
else{
    $limit=3;
}

//A few lines down -->    

<form action="<?php $_SERVER['REQUEST_URI']?>" method="post">
    Items: <input type="text" name="item">
    <input type="submit" name"go" value="Go">
</form>

You could add SESSION use this way:

$item = $_REQUEST['item'];
if(isset($_REQUEST['item'])){
    $limit=$item;
    $_SESSION['item_limit'] = $limit;
}
else{
    // If we find a limit set in the session use that
    if (!empty($_SESSION['item_limit']) {
        $limit = $_SESSION['item_limit'];
    }
    else {
        $limit=3;
    }
}
