PHP Variables accessible by JavaScript?

cavey

You know those mouse over pop up boxes that you can do in JavaScript? I have links that where would cool if you mouse over them and a user's account info was displayed, so you could quickly read it instead of loading a page... but is it possible to push PHP server side values over to client side javascript?

I guess you'd have to put the values in a string and use the GET method to explode them from the URL, is that the only way?

Can I just do this?

var name = "<? $name ?>";

</script>

Well, you need to actually tell PHP what to do with that variable (ex. echo() it), but yeah, that's generally one way to pass PHP variables along to JavaScript.

This is the code
<script>

var name = "<?php echo $name ?>";

</script>

Well that works only once... once the php script has been parsed and send to the browser you can't change the name variable with PHP anymore.

I guess you should look into AJAX.

Another way you could do this is to load a dynamically created image into that popup box...

And write a javascript that creates the popup box and fills it with an image source like img.src = "imagecreator.php?uID='+usersID

Another way, which is not the very best, is to have an iframe in the popup box and load the correct info into that... iframeID.src "userInfo.php?uID='+usersID

Loads of ways...
