I'll keep this short and sweet, I want to load a JS file in the admin panel as part of my plugin, and through tons of research I have a few different options that have all ended with the same problem that no one else seems to be experiencing so finally I'm posting for a solution here.

When I use the following code I get an error:

function register_scripts(){
function payee_init($hook){

add_action ("admin_print_styles-post.php", "payee_init");
add_action ("admin_init", "register_scripts");

ERROR: /wp-content/plugins/iBudget/modules/payee/iBudget/modules/payee/payee.js/?ver=3.3.1:1 Uncaught SyntaxError: Unexpected token <

No matter how I attempt to enqueue the scrip I get this error even though the JS file simple says: alert("test");

Now the interesting nugget is this, if I include the JS directly in the function everything works fine:

function payee_init($hook){
add_action ("admin_print_styles-post.php", "payee_init");

Basically I need to know why this error is coming up, I believe I'm loading the script correctly for what I need but not sure why this conflict is there and not even sure where else to look for a solution.

Thanks guys!

You action filter is wrong.

First change this function name function register_scripts , it's a bad name, use something unique.

Second change add_action ("admin_print_styles-post.php", "payee_init");

to a proper hook like add_action ("wp_enqueue_scripts", "payee_init");


  • Thanks for your feedback on this. Had to take a quick break from that project so haven't had the chance to try your suggestion but I'll let you know once I do it. Thanks a lot! Commented May 9, 2012 at 22:40
  • wp_enqueue_scripts is for loading scripts on the front end. You'd want to use admin_enqueue_scripts for the admin side.
