I have this jquery code inside my wordpress admin page that checks if the input value is empty.


     var link = $j('#input').val();
    if(link == ''){
         alert('hi there');



Now if the form is empty it will alert ' hi there'.

the plugin works fine but the alert does not show on the main page. Only in the admin section.

what would be the problem?

here is how I am calling jquery.

function test(){
wp_enqueue_script('myscript', plugin_dir_url(__FILE__). 'js/test.js');


I would like that if the value of input is empty, the alert show also in the wordpress homepage and not only in the admin page.

  • The first bit of javascript is where exactly? In your test.js file?

  • how about testing your js in jsbin? here is my test jsbin.com/omumit/edit#javascript,html Jun 21, 2012 at 17:54

I believe the problem is that you are enquequeing jquery.

You don't need to do that, as WordPress does it by default. Just remove


and everything should be fine.

  • that will never work. this is a plugin and I am calling jquery.

  • But you do not need to call jQuery! Trust me, I have recently submited plugin to WordPress.org and before approving it, I needed to remove jQuery call. There is no need for calling jQuery with plugins! Jun 21, 2012 at 16:35
  • ok well... gave that a shot too.. no changes.
