PHP strict error on ACF 4.1.8+

Following the change made on ACF 4.1.8 I am getting this error, running on php 5.4 in strict mode.

Strict Standards: Only variables should be passed by reference in …wp-content/plugins/advanced-custom-fields/core/fields/_functions.php on line 55

To solve it should be only creating a var before to hold the “$found = false” and send it to the wp_cache_get.

The same aplies to 2 other files, as far as I know:
core/controllers/field_group.php
core/api.php

Thanks for looking into it!

Hi @andrefelipe

Thanks for the bug report.

So just to clarify, passing $found = false within the parameter space is causing an ERROR in PHP?

And the fix is to create $found before the wp_cache_get function?

These changes have been made and pushed to the latest files on github!

wonderful, that was exactly it! That way the var is correctly referenced.

Thanks a bunch!
