$ not defined using jQuery in Wordpress
Ok, so I'm having some trouble here. I'm customizing a plugin. I need a text field to automatically populate with the text of a drop down menu when an option is selected. The ID's of both elements are created on age load via php; however the IDs do not change. The id for the is "field_new_post_category" and the id of the text field is "post_title" This is what I have so far:
I have this working well in a JSFiddle here: http://jsfiddle.net/XVDH2/39/
The trouble is that when I put it all together in Wordpress, it doesn't work. Simply nothing. I make the selection and nothing changes.
Thanks for any help you might be able to offer. :)
