I have this simple Select box that is suppose to store the selected value in a hidden input, which can then be used for POST (I am doing it this way to use data from disabled drop down menus)
<body>
<?php
$Z = $_POST[hdn];
?>
<form id="form1" name="form1" method="post" action="test.php">
<select name="whatever" id="whatever" onchange="document.getElementById('hdn').value = this.value">
<option value="1">1Value</option>
<option value="2">2Value</option>
<option value="3">3Value</option>
<option value="4">4Value</option>
</select>
<input type="hidden" name ='hdn' id="hdn" />
<input type="submit" id='submit' />
<?php
echo "<p>".$Z."</p>";
?>
</form>
</body>
The echo call works for the last 3 options (2,3,4) but if I select the first one it doesnt output anything, and even if i change first one it still doesnt output anything.
Can someone explain to me whats going on, I think it might be a syntax issue.
