JavaScript Error: wpColorPicker is not a function

[technotarek]

I'm getting this error when running the plugin and I think it is adversely affecting the WYSIWYG editor (e.g,. can't insert links; can't toggle to the 'text' tab etc).

WordPress Version: 4.4.1
Plugin Version: 2.1.0

Triggered by:

$('.at-color').wpColorPicker();

Happy to try to pitch in and help -- would be great if you could point me in the right direction though.

I confirmed that commenting out lines 63 and 157 of tax-meta-clss.js removes the errors (obviously) and that doing so also restores the other broken functionality that I had mentioned. Is there a known substitute for wpColorPicker? Is the only role it plays is to allow selecting a color in the WYSIWYG?

@technotarek I got the same error and wrote a fix for the issue here: #122.

Do you mind testing it to see if it works for you?

[technotarek]

@Akamaozu I ended up using an alternative approach and am no longer using this plugin.

First, excellent library. Thanks for the hard work!

I had this issue too. In my case I was using the color picker which worked when I was creating terms, but not when editing a term (ie: /wp-admin/edit-tags.php vs /wp-admin/term.php). Turns out the is_edit_page() check was only returning true for edit-tags.php and therefore the enqueues for the styles and scripts weren't getting fired. So in Tax-meta-class.php line 1133 I changed the function check from:

public function is_edit_page() { global $pagenow; return ( $pagenow == 'edit-tags.php' ); }

to:
public function is_edit_page() { global $pagenow; return ( $pagenow == 'edit-tags.php' || $pagenow == 'term.php' ); }

and all seems to be well.

I'll get this forked and do a pull request later, but thought this may help someone in the meantime.

Another and in my opinion quickest fix would be to add wp-color-picker as a dependency for tax-meta-clss script at line 162.

@Mathiu but that means loading wp-color-picker even when it's not going to be used.

If every other plugin behaved that way, you'd quickly end up with a bloated WordPress installation.

I wrote a solution (#122) that takes the other approach: doesn't blindly execute the color picker function if it doesn't need to.

It solved other people's problem: #117

Would appreciate it if you can check that it solves yours.

@Mathiu thanks, solved it for me. I'm not using a colour picker. I suspect if I used one, this wouldn't help though. Won't be needing it, so that will remain conjecture.

Wordpress? Bloat? Surely not!! LOL
