Problem with function_exists() after 4.3.0 update

I have a functionality plugin that uses the following to check for the get_field() function:

if ( !function_exists( 'get_field' ) ) 
	return;

After updating ACF to 4.3.0, the function works as expected for functions.php. But for the functionality plugin, “!function_exists( ‘get_field’ )” returns true. Before the update it returned false.

Even though “!function_exists( ‘get_field’ )” returns true, the get_field() function still works.

I have the Gallery and Repeater Field add-ons installed. Deactivating these and all other plugins produced the same results.

Any suggestions why function_exists() cannot find get_field() function outside of functions.php?

Thanks

Hi @farmboy

Does your plugin run before or after ACF?

Thanks

The plugin folder name starts with “custom”, so it should run after ACF. I’m assuming active plugins are loaded alphabetically by there folder name.

Hi @farmboy

I think I know what the issue is.
v4.3.0 used a hook called ‘plugins_loaded’ to then load in the API. This has now been reported as a bug and I have already removed the hook and updated the github version.

A new 4.3.1 will be out soon including this fix and some others.

Perhaps this will explain what is going on?

Thanks
E

Thanks for the update Elliot. This has also caused issues with several sites running on a theme that requires ACF:

if(is_plugin_active('advanced-custom-fields/acf.php') == true && function_exists('get_field')) {

    include('myfile.php');

}

Looking forward to the new version soon! :]

Elliot,

Yes that would seem to explain the issue. I appreciate you fixing the bug in the next release.

Thanks Devin for reporting this issue as well.
