i’m stumped. unless this functionality is hooked into some other code in the the GP theme i’m not seeing/including. * thanks so much for your help! * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [getting join() error with undefined $classes variable](https://wordpress.org/support/topic/getting-join-error-with-undefined-classes-variable/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/getting-join-error-with-undefined-classes-variable/#post-14030148) * forgot a link: [https://gist.github.com/LGitHub-sprout/467fe0db38eafeacabc44ea9cb737a0c](https://gist.github.com/LGitHub-sprout/467fe0db38eafeacabc44ea9cb737a0c) * Forum: [Themes and Templates](https://wordpress.org/support/forum/themes-and-templates/) In reply to: [[GeneratePress] generate_do_element_classes](https://wordpress.org/support/topic/generate_do_element_classes/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/generate_do_element_classes/#post-13977165) * forgot to mark it solved * Forum: [Themes and Templates](https://wordpress.org/support/forum/themes-and-templates/) In reply to: [[GeneratePress] generate_do_element_classes](https://wordpress.org/support/topic/generate_do_element_classes/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/generate_do_element_classes/#post-13977162) * thank you, Tom <3 will def look into that. i feel so lucky to be able to learn with GP and get a response to a Q. truly grateful <3 * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [can’t get simple menu working](https://wordpress.org/support/topic/cant-get-simple-menu-working/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/cant-get-simple-menu-working/#post-13962152) * haha thanks, BC! * perhaps you won’t believe it, but i’m actually from Denver, Lol. so, you’re psychic in addition to other talents. * i posted the solution and gave credit to [@rup](https://wordpress.org/support/users/rup/) who helped me. * Be Well <3 !! * Forum: [Everything else WordPress](https://wordpress.org/support/forum/miscellaneous/) In reply to: [can’t browse themes in customizer when requiring files w content](https://wordpress.org/support/topic/cant-browse-themes-in-customizer-when-requiring-files-w-content/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/cant-browse-themes-in-customizer-when-requiring-files-w-content/#post-13962141) * BIG thanks to stackexchange WP user, [@rup](https://wordpress.org/support/users/rup/) for help! * “But if that’s actual content you want to render into the page then you don’t want to be requiring it like that from the top level of your theme file: maybe from inside a function that you then call from one of your page templates, probably header.php? If you are rendering out from the theme’s functions I could imagine that might break the theme customisation pages, yes.” Rup Dec 16 ’20 at 22:19 * answered my own Q with [@rup](https://wordpress.org/support/users/rup/)’s help. * rendering out directly from the required file was at least part of the problem. * i believe the other part was not rendering from inside a function as well as not hooking all of that functionality into an action in the target file. * the problem vanishes and the content renders properly when these steps are followed: * require the file in functions.php using built-in WordPress function to the current theme’s template directory as indicated above. * create a simple action hook in the target file using `do_action()` function: * `do_action( 'namespace_hook_name' );` * create a (pluggable, if necessary) function in required file to render desired content (below is based on GeneratePress formatting). $priority and $accepted_args optional: * ``` if ( ! function_exists( 'namespace_func_name' ) ) { add_action( 'namespace_hook_name', 'namespace_func_name', $priority, $args ); function namespace_func_name() { // code to render } } ``` * search commercial themes for how they use action hooks as well as WordPress’s own default themes to learn more and practice. * [https://developer.wordpress.org/reference/functions/do_action/](https://developer.wordpress.org/reference/functions/do_action/) * [https://developer.wordpress.org/reference/functions/add_action/](https://developer.wordpress.org/reference/functions/add_action/) * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [can’t get simple menu working](https://wordpress.org/support/topic/cant-get-simple-menu-working/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/cant-get-simple-menu-working/#post-13918624) * i’m smh… yup, it was a typo :/ * well, it happens to the best of folks, so i take it w a grain of salt. * i found an answer to this problem: [https://wordpress.org/support/topic/cant-browse-themes-in-customizer-when-requiring-files-w-content/](https://wordpress.org/support/topic/cant-browse-themes-in-customizer-when-requiring-files-w-content/) * should i post the solution, or does it matter? * thanks for your time, BC. * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [can’t get simple menu working](https://wordpress.org/support/topic/cant-get-simple-menu-working/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 8 months ago](https://wordpress.org/support/topic/cant-get-simple-menu-working/#post-13909551) * it works if i remove the `theme_location` from `wp_nav_menus`. * now the ‘container_class’ and ‘container_id’ also work without the `theme_location`. * why? * Forum: [Themes and Templates](https://wordpress.org/support/forum/themes-and-templates/) In reply to: [[GeneratePress] require stmt jumbles element](https://wordpress.org/support/topic/require-stmt-jumbles-element/) * Thread Starter [sprowt](https://wordpress.org/support/users/sprowt/) * (@sprowt) * [5 years, 9 months ago](https://wordpress.org/support/topic/require-stmt-jumbles-element/#post-13786467) * thank you, [@ejcabquina](https://wordpress.org/support/users/ejcabquina/), for your reply. * when i require a file in my own theme like this: * `require get_template_directory .
