Question

my php configuration on server are showing i can post variables to maximum size upto 8MB , thats enough .. but how to check for number of variables , sever is running ubuntu 4.4 , php .

i have a page which takes students marks and send them to a action page , but on action page doing echo for the post variables nothing is being displayed , where are doing an echo “hello”; this shows …

this is the page which sends the variables

<form name="frm" action="marklistI.php" method="POST" class="" >
    <?php $tb->displayTable() ?>
    <div class="mainframe">
        <input type="hidden" name="batch" value="<?php print $_GET['batch']; ?>"/>
        <input type="hidden" name="sem" value="<?php print $_GET['sem']; ?>" />
        <input type="hidden" name="chance" value="<?php print $_GET['chance']; ?>"/>
        <input name="submit" type="submit" class="hide" value="Save"/>
        <input type="hidden" name="url" value="<?php print $_SERVER['REQUEST_URI']; ?>"/>
    </div>
</form>

$dept =$_COOKIE['dept'];
$join=$_POST['batch'];
$type='e';
$sem=$_POST['sem'];
$chance=$_POST['chance'];

Answer 1

try placing this code on your action page:

if (isset($_GET)) {
    echo "<h3>GET METHOD</h3>";
    var_dump($_GET);
}
if (isset($_POST)) {
    echo "<h3>POST METHOD</h3>";
    var_dump($_POST);
}
if (isset($_COOKIE)) {
    echo "<h3>COOKIE METHOD</h3>";
    var_dump($_COOKIE);
}

See which method returns your variables and use it, otherwise, you are not filling any values on the form.
