通过url将javascript var传递给PHP

Question

I have two javascript variables var 1 and var 2 which I need to pass to PHP through GET method.

$('#output_images').html('<img src="MergeIcons.php?icon1=var1&econdIcon=var2 />');

In my .php file, I merge two icons using GD PHP and send the image back using imagepng.

$firstIcon = $_GET['icon1'];   
$secondIcon = $_GET['icon2'];  

// Process images

header('Content-Type: image/png');
imagepng($dest);

When I pass the direct image path and dont use the var1 and var 2 it works fine, but with var1 and var 2 it doesnt work. What could be the problem?

Answer 1

Currently you are sending var1 and var2 to PHP as strings. They need to be sent as variables...

$('#output_images').html('<img src="MergeIcons.php?icon1='+var1+'&econdIcon='+var2+'" />');
