PHP is parsed before client scripting, including JS. So you can't transfer JS var's to PHP.

You can pass it in an URL:

Code:

window.location = 'index.php?txt=' + txt;

and then in PHP access it with

PHP Code:


			
$_GET['txt']

what i did is this

CODE:
<script language="javascript">
function tf()
{
if (actiontype.options[actiontype.selectedIndex].value == "1" || actiontype.options[actiontype.selectedIndex].value == "2" || actiontype.options[actiontype.selectedIndex].value == "8" || actiontype.options[actiontype.selectedIndex].value == "15")
var txt='true';
else
var txt='false';
window.location = 'menu.php'index.php?txt=' + txt;
}

i tried this one but it did not work..please correct my code.
if ($_GET[txt]==true)
echo '<td class="table-list-title" id="s">Interview Schedule</td>';

You have an extra single-quote in there. It should be a forward-slash.

PHP Code:


			
if ($_GET['txt'] == 'true')

PHP Code:


			
<script language="javascript">

function tf()

{

if (actiontype.options[actiontype.selectedIndex].value == "1" || actiontype.options[actiontype.selectedIndex].value == "2" || actiontype.options[actiontype.selectedIndex].value == "8" || actiontype.options[actiontype.selectedIndex].value == "15")

var txt='true';

else

var txt='false';

if (txt != '<?php echo $_GET['txt']; ?>')

window.location = 'menu.php?txt=' + txt;

}

</script>

<?php

if ($_GET['txt']=='true')

echo '<td class="table-list-title" id="s">Interview Schedule</td>';

?>

is it not need to call the function tf()..all i need to do is get the value of txt?

meshi · 08-31-2007, 02:57 PM

still it didnt work

Mwnciau · 08-31-2007, 03:10 PM

It works fine for me when I remove

if (actiontype.options[actiontype.selectedIndex].value == "1" || actiontype.options[actiontype.selectedIndex].value == "2" || actiontype.options[actiontype.selectedIndex].value == "8" || actiontype.options[actiontype.selectedIndex].value == "15")

, looks like you have a javascript error.

meshi · 08-31-2007, 03:58 PM

        document.all('div_two').style.display =  "none";

Mechelle I told you Bahamut is the best. hehehhe

Nightfire · 08-31-2007, 05:31 PM

There's no point in using php to echo out those divs etc if js and css is controlling them
