Echo javascript with a php function inside?

Question

Oh boy! I cant get this to work. Any ideas on what the heck I'm doing wrong? Here's the code.

I'm trying to echo the script but use a php function to get the directory of the js file!!

Any help would be appreicated!!

echo '<script src="<?php get_some_function();?> . /js/main.js"></script>';

I've tried dif scenerios with escaping but cant get this to output correctly.

Answer 1

Since you're already in the PHP context, you can simply concatenate the strings, like so:

echo '<script src="' . get_some_function() . '/js/main.js"></script>';

Using sprintf() looks more cleaner, though:

echo sprintf('<script src="%s/js/main.js"></script>', get_some_function());

Answer 2

Instead of opening another script tag inside the string, concat the string and echo. The <?php within your string will not be evaluated.

echo '<script src="'. get_some_function() . '/js/main.js"></script>';
