How can I use a JavaScript variable as a PHP variable?
I need to use javascipt variables in PHP, how can I do that?
eg:
<script>
var abc = 'this is text';
</script>
How can I read variable abc in php?
One way of doing it is to make use of a hidden text/input box.
<input type=text style=display:none id=hiddenVal />
In the Javascript assign the variable to the input box.
<script>
function loadValues()
{
var abc = 'this is text';
document.getElementById(hiddenVal).value = abc;
//alert(document.getElementById(hiddenVal).value);
}
</script>
<body onload=loadValues();>
<form action=processing.php method=post>
<input type=text style=display:none id=hiddenVal />
<input type=submit name=submit id=submit value=Submit />
</form>
</body>
This is one method to allow you to use Javascript variable and post it to the backend. Alternatively if you want to display these values just remove the
style=display:none
on the control.
Now after the post occurred one should be able to pick up the variable using processing.php
<?php
echo $_POST[hiddenVal];
?>
Very dirty way of doing this but does the trick.
