using javascript pass value in hidden field to a condition written in php

[thumuluru]

Hi All,
I have a problem. See the following code

<form name="profilecapture">
<?php
$required = true;
?>
FNAME
<?
if($required==true){
echo "<span id=\"a\">*</span>";
}
?>
:<input type="text" name="fname">
<input id = "11" type="checkbox" onClick="showhide('a','11');">
<script language="javascript" type="text/javascript">
function showhide(id,id1){
var chk = document.getElementById(id1).checked;
var makemandatory;

if(document.getElementById(id1).checked){
makemandatory = true;
document.getElementById(id).style.visibility = "visible";
document.profilecapture.abc.value="true";
}else{
makemandatory = false;
document.getElementById(id).style.visibility = "hidden";
document.profilecapture.abc.value="false";
}};
</script>
<input type="text" name="abc">
</form>

What I'm doing here is,

If required is true
then dispaly
else
do not display

Now what I want is I need to display the * if required is true & chk box is selected. To do this I'm taking the value of chkbox (selected or not) to a hidden field abc. But I ned to use this value in the above condition.
So the condition looks like

If required is true or chkbox is selected i.e abc==true
then dispaly
else
do not display

How to do this.
Can some one plz help me in this. I badly need this. My customer is waiting

hi,

Hm..

Not exactly cler here. You do know that PhP can only check formfields if the form is submitted?

Javascript & PhP "Live" in seperate locations!

Hi leatherback,

See if this makes sense

<form name="profilecapture">
<?php

/*
after this simple script content of PHP variable $s_wid will be
JavaScript variable s_wid which is screen.width
*/

ob_start();

?>

<SCRIPT LANGUAGE="JavaScript">
var s_wid = 0
//s_wid = screen.width
s_wid = document.profilecapture.abc.value;
//document.write(s_wid);
//document.write('');

</SCRIPT>
<INPUT type="text" value="test" name="abc"/>

<?php
$v = "<script>document.write(s_wid);</script>";
$s_wid = ob_get_contents();
echo $s_wid,"-----11<br>";
echo $v,"---22<br>";
ob_end_flush();
?>
</form>
Thanks
