Displaying a variable in a popup window

[mikenowo]

For testing purposes, how can I display a variable in a popup window to see if the value is correct?

i.e. in javascript I can do it with this line:

 alert("Value: " + var_name);

Is there a similar command in PHP to help debug?

Nope. No popup from PhP directly:
PhP is serverside scripting.
You can of course echo this variables value to your browser...

I'd do it how leatherback said... just use a PHP echo statement to echo your value to the javascript alert code.

er.. and how is this done?

[Erkilite]

echo popup_alert('javascript rules!.');

function popup_alert($text){

$field= '<script language="JavaScript">';
$field.='alert('.$text.');';
$field.='</script>';

return $field;

}

My appologies... got called away from my desk, and when I came back, hit "Submit", thinking I'd written you some code before I left. Erkilite has it right for you though.
