Title: PHP Errors Last modified: December 18, 2016 --- # PHP Errors * Resolved [michent1](https://wordpress.org/support/users/michent1/) * (@michent1) * [9 years, 5 months ago](https://wordpress.org/support/topic/php-errors-95/) * Getting the following warning & notice in the CFIX admin page on local install running php 5.6: * `Warning: Illegal string offset '' in E:\***\wp-content\plugins\category-featured- images-extended\settings.php on line 49` Traceback: * `Notice: Uninitialized string offset: 0 in E:\***\wp-content\plugins\category- featured-images-extended\settings.php on line 49` * After some additional debugging, it occurs when the global fallbacks aren’t defined in the settings. The errors no longer display once the global fallback image, category & tag is set. * Other than that, works like charm 🙂 Thanks for the awesome plugin!

Those pesky offset warnings will sneak up on you when you least expect it – and have a way of clogging up a debug log even when the underlying problem does not actually affect functionality. * I’ve just pushed out an update that should take care of them. If you get a chance, I hope that after you’ve updated, you’ll be able confirm on your end that they’re gone. * Please let me know if it’s still a problem, or if you run into any others. I also hope that you’ll take the time to give the plug-in a high rating, as it or I am still working back from an ill-considered 1-star rating/review! * Thread Starter [michent1](https://wordpress.org/support/users/michent1/) * (@michent1) * [9 years, 5 months ago](https://wordpress.org/support/topic/php-errors-95/#post-8566648) * Some folks just don’t appreciate the time/work that goes into dev & maintenance with this stuff. * I’d like to submit a feature request for the future dev roadmap. * – Random featured images based on taxonomy. Allowing users to add multiple images per taxonomy term. Posts would then grab a random image from it’s category/tag set as a featured image. – Would work well in instances where archive views pull thumbs, allowing a mix of featured image thumbs vs the same image repeating for each post in a category. * Plugin Author [CK MacLeod](https://wordpress.org/support/users/ck-macleod/) * (@ck-macleod) * [9 years, 5 months ago](https://wordpress.org/support/topic/php-errors-95/#post-8566899) * Thanks for the suggestion (and for the rating and review!). * I had another user make a similar request a while back, and have seen why it makes sense in archives at my own sites, though I can also think of several ways in addition to the group/random option to address the underlying problem. Anyway, please feel free to use the contact link at the bottom of the plug-in settings page if you’d like to discuss the feature or alternatives further. Either way, I’ll certainly add your alternative to the roadmap. * Thread Starter [michent1](https://wordpress.org/support/users/michent1/) * (@michent1) * [9 years, 5 months ago](https://wordpress.org/support/topic/php-errors-95/#post-8566939) * Sure. I found another plugin that has the random featured image functionality, but it’s not a stable version (throwing quite a few errors affecting functionality). Submitted a bug report to the developer, so we’ll see if she looks into it. * But after digging through the code, the logic for the random image function is pretty straight forward. Something along the lines of: * ``` function get_random_image() { $all_images = apply_filters( 'all_images', array() ); // Get out if the user didn't upload any random images if ( ! is_array($all_images) || empty($all_images) ) return false; // If there is only 1 image, return that single image if ( count($all_images) === 1 && !empty($all_images[0]) ) return $all_images[0]; // Grab a random image and return it $random_image = array_rand($all_images, 1); return $random_image; } ``` * *Note: unchecked code. Just a guess. * Plugin Author [CK MacLeod](https://wordpress.org/support/users/ck-macleod/) * (@ck-macleod) * [9 years, 5 months ago](https://wordpress.org/support/topic/php-errors-95/#post-8569313) * Yeah, randomizing the images in a returned array and selecting one isn’t the hard or time-consuming part. Constructing the user interface and options might be. Also not sure whether to expect performance problems. Anyway, like I said, this discussion would probably be more appropriate via email than in this support forum, but thanks again for the suggestion. If I weren’t in the middle of some other projects, I’d get right on it today, because in addition to suggesting an improvement in the plugin it’s interesting!
