Title: Compatibility Issue with WP_Stack Last modified: August 21, 2016 --- # Compatibility Issue with WP_Stack * Resolved [clariner](https://wordpress.org/support/users/clariner/) * (@clariner) * [12 years, 11 months ago](https://wordpress.org/support/topic/compatibility-issue-with-wp_stack/) * We have come across with an issue incompatibility issue with WP_Stack ([https://github.com/markjaquith/WP-Stack](https://github.com/markjaquith/WP-Stack)) * The issue is with the usage of ABSPATH, in the ‘get’ function and ‘get_path’ function. * In the ‘get’ function ABSPATH should be removed from myCRED_ADDONS_DIR but as we use WP_Stack it is not and so when ‘get_path’ function is called ABSPATH is then appended to the file path which makes the file path invalid. * The result is that addon setting pages are not loaded when activated. * I have updated the two functions below to add support for wordpress installs based on WP_Stack * ``` public function get( $save = false ) { $prefix = 'myCRED-addon-'; $addon_location = myCRED_ADDONS_DIR; $installed = array(); // Search for addons. should be in addons/*/myCRED-addon-*.php $addon_search = glob( $addon_location . "*/$prefix*.php" ); if ( !empty( $addon_search ) && $addon_search !== false ) { foreach ( $addon_search as $filename ) { // Handle windows if ( !defined( 'WP_STAGE' ) ) { $abspath = str_replace( '/', '', ABSPATH ); // Remove ABSPATH to prevent long string addresses. Everything starts with wp-content $sub_file = str_replace( array( $abspath, ABSPATH ), '', $filename ); } else { $sub_file = $filename; } // Get File Name preg_match( '/(.{1,})\/(.{1,})/', $sub_file, $matches ); $sub_file_name = $matches[2]; // Get Addon Information $addon_info = $this->get_addon_info( $filename, $matches[1], $sub_file_name ); // Check if addon has a requirement to prevent errors due to calls to non existing functions if ( isset( $addon_info['requires'] ) && !empty( $addon_info['requires'] ) && !function_exists( $addon_info['requires'] ) ) { continue; } // Prevent Duplicates if ( !array_key_exists( $sub_file_name, $installed ) ) { $installed[$this->make_id( $sub_file_name )] = $addon_info; } } } unset( $addon_search ); $installed = apply_filters( 'mycred_setup_addons', $installed ); if ( $save === true && $this->core->can_edit_plugin() ) { $new_data = array( 'active' => $this->active, 'installed' => $installed ); update_option( 'mycred_pref_addons', $new_data ); } $this->installed = $installed; return $installed; } ``` * ``` public function get_path( $key ) { $installed = $this->installed; if ( array_key_exists( $key, $installed ) ) { $file = $installed[$key]['file']; if ( !defined( 'WP_STAGE' ) ) { return ABSPATH . $installed[$key]['folder'] . $file; } else { return $installed[$key]['folder'] . $file; } } return ''; } ``` * Hope these changes can be included in version 1.1? * [http://wordpress.org/extend/plugins/mycred/](http://wordpress.org/extend/plugins/mycred/) Viewing 3 replies - 1 through 3 (of 3 total) * Plugin Author [myCred](https://wordpress.org/support/users/designbymerovingi/) * (@designbymerovingi) * [12 years, 11 months ago](https://wordpress.org/support/topic/compatibility-issue-with-wp_stack/#post-3805296) * Wow. Appreciate you taking the time to report this and your provided solution. I will look into this asap and make sure to include it in the next update. * Right now I am going through all the 1.1 requests and calculating the time it will take to implement it. My aim is to have 1.1 out in a week or two, so I might just push though a 1.0.9.4 before then to address this issue. * Thread Starter [clariner](https://wordpress.org/support/users/clariner/) * (@clariner) * [12 years, 11 months ago](https://wordpress.org/support/topic/compatibility-issue-with-wp_stack/#post-3805336) * Hi Gabriel, * No problem, always happy to help. * I’m happy to wait until 1.1 if you development window is that short. * On a side question, do you have either a skeleton addon or tutorial about creating one? * Plugin Author [myCred](https://wordpress.org/support/users/designbymerovingi/) * (@designbymerovingi) * [12 years, 11 months ago](https://wordpress.org/support/topic/compatibility-issue-with-wp_stack/#post-3805597) * I have a low work load for June so I thought I take the opportunity and spend it on myCRED, hence the short window. * Creating a tutorial on Add-ons has been on my mind for a while now but I have been unhappy with some aspects that I feel could be made simpler or more explanatory. I do not have a skeleton addon right now as I mainly just use the abstract module class as reference but if you give me a few days I would be more then happy to put one together for you.
