Javascript &amp;&amp; PHP

Javascript && PHP

Anon

Here is something I tried...

<SCRIPT LANGUAGE="JavaScript">
function setVar()
{
document.frm.php_var.value='done';
document.frm.submit();
}
</SCRIPT>

<?
if ($php_var == '')
{
print "<script>setVar()</script>";
}

echo $php_var;
?>

in my case it is hopefully going to be used to ascertain the browser type and set some variables...this seems like a very sneaky way around though and Netscape with it 'Transfer Interrupted' message pretty much sums it up.

Is there any other way to pass on a java scipt var to php??

the code above has been compiled from ideas introduced from the forum 🙂

This will pass phpvar defined in Javascript, to your script (script opens itself).

if (!$php_var)
echo'

<SCRIPT LANGUAGE="javascript">
 function onLoad(){
   document.frm.phpvar.value=100;
 }
</SCRIPT>

<BODY onLoad="javascript:onLoad();">
<FORM NAME="frm" ACTION="'.$PHP_SELF.'" METHOD="POST">
<INPUT TYPE="HIDDEN" NAME="phpvar">
</FORM>
<SCRIPT LANGUAGE="javascript">
  document.frm.submit();
</SCRIPT>
</BODY>
';

else
echo $phpvar;

At the first line - not $php_var :-))), but $phpvar, of course...

if (!$phpvar)
echo'

<SCRIPT LANGUAGE="javascript">
function onLoad(){
document.frm.phpvar.value=100;
}
</SCRIPT>

<BODY onLoad="javascript:onLoad();">
<FORM NAME="frm" ACTION="'.$PHP_SELF.'" METHOD="POST">
<INPUT TYPE="HIDDEN" NAME="phpvar">
</FORM>
<SCRIPT LANGUAGE="javascript">
document.frm.submit();
</SCRIPT>
</BODY>
';
else
echo $phpvar;
