AddFunc Head & Footer Code

1. 

   Simply paste your code into one of these three fields and it will be included on every page of your website.

2. 

   Add your code to these fields respectively and it will output specifically to this page, post or custom post type. Optionally replace or remove the site-wide code on any individual post or page.

Can I add Google Analytics or other tracking code snippets to the ⟨head⟩ tag of my website?

Yep! That’s what AddFunc Head & Footer Code is made for.

Can I add code snippets to the ⟨head⟩ tag or footer of a specific Post or Page?

Yep! That’s what this plugin is made for.

Does AddFunc Head & Footer Code work on custom content types, the same as they do on Posts and Pages?

For the site wide code yes, as long as the theme is set up properly with the wp_head() and wp_footer() functions. For individual custom content type “entries” (as we’ll call them) it will work as long as the custom content type (or custom post type more precisely) is set up in the standard way, so that WordPress will recognize that it needs to add all the usual meta boxes to it. Basically, it will work in a standard setup.

Where does the Head Code output?

Wherever wp_head() is located in your theme.

Where does the Body Start Code output?

Immediately after the opening body tag. Note: other plugins can be made to do the same thing and one of them has to insert before the other, so other plugins could theoretically insert code before AddFunc Head & Footer Code’s Body Start Code.

Where does the Footer Code output?

Wherever wp_footer() is located in your theme.

Will AddFunc Head & Footer Code work if there is no `wp_head()` or `wp_footer()` in my theme?

Wherever one of those functions is missing, your code will not be output there. But omitting one of them does not stop the other ones from working. AddFunc Head & Footer Code will also save your code regardless. It just can’t output your code without the presence of those functions in the theme.

Does AddFunc have a website?

Yes. addfunc.com

  • Note: There is no standard for opening body tag code in WordPress yet (contact me if I’m wrong). If there ever is, AddFunc Head & Footer Code may change so as to conform to the standard. We don’t think this will effect performance in anyway, but if it does, we will let you know through this change log. If necessary, we may even leave this feature in place along with the new standardized method.

• Corrects the generated path to options.php, so that the settings page can be found even on installs where the plugins directory is not at the standard /wp-content/plugins location.

1.2

19 Jun 2015

• Discovered addfunc-head-footer-code.php was saved with text encoding Western (Mac OS Roman). ~>:( Changed to Unicode (UTF-8).
• This was probably changed during a recent update on the plugin’s tags (the tags for the WordPress Plugin Repository), so maybe two weeks ago. Previous downloads should have been UTF-8.
• Also changed version 1.1 to UTF-8 because leaving a Mac OS Roman version in the repository would be pointless. So 1.1 and 1.2 are the same, except for the readme.txt.
