Why for loop in javascript is reseting a PHP variable

Jul 25th, 2008

Hi

I am in a bit of fix. I am developing a module in PHP where I am using javascripts to validate the data entered by the user. Now the problem is that I am firing a query to the database through PHP and hence storing its results in PHP variables. To validate a form I have to check whether the data entered by the user matches with database or not.

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
var i,x=0;
	<?php $ind=0; ?>
	for(i=0;i< <?php echo $num ?>;i++) 
	{
		alert(<?php echo $ind; ?>);
		if(fobj.username.value== <?php echo "\"".$uname[$ind]."\"";?>)
		{
			alert(<?php echo "\"".$uname[$ind]."\"";?>);
			x=x+1;
			alert("if");
		}	
		alert("loop");
		<?php $ind++; ?>
		alert(<?php echo $ind;?>);
	}
	if(x>=1)
	{
		alert("Can't login. User Name has expired.");
		return false;
	}
var i,x=0;
	<?php $ind=0; ?>
	for(i=0;i< <?php echo $num ?>;i++) 
	{
		alert(<?php echo $ind; ?>);
		if(fobj.username.value== <?php echo "\"".$uname[$ind]."\"";?>)
		{
			alert(<?php echo "\"".$uname[$ind]."\"";?>);
			x=x+1;
			alert("if");
		}	
		alert("loop");
		<?php $ind++; ?>
		alert(<?php echo $ind;?>);
	}
	if(x>=1)
	{
		alert("Can't login. User Name has expired.");
		return false;
	}

The above given code is written in tags of javascript. Now what's happening is that variable $ind is reseting itself when the loop starts again. At the end of loop if it's value is 1 then it becomes 0 when it reiterates the loop again.

What's going on guys. How could I retain the value of $ind

Commitment is what transforms a promise into reality. It is the words that speak boldly of your intentions. And the actions which speak louder than the words. It is making the time when there is none. Commitment is the stuff character is made of; the power to change the face of things. It is the daily triumph of integrity over skepticism.
