@pzstar it is a good approach to check if your variables are assigned a value or not. If a variable or an index in an array is not declared/assigned then you’d probably get such error. I would suggest you to use isset(). <input id=”welcome_post_char” type=”text” name=”abc_options[welcome_post_char]” value=”<?php echo (isset($settings[‘welcome_post_char’]))? esc_attr($settings[‘welcome_post_char’],’abc’): ”}; ?>”>
I couldn’t figure out a WordPress way to do this and looking at the WP source, it looks like this probably will never really be possible. However, I was able to get a solution using vanilla PHP by redirecting standard output into a buffer and loading the buffer into a variable. $listings = new WP_Query(…); … Read more
You need to put a correct code into the header.php , currently you are putting [metaslider id=36] , which is not correct, you need to replace it with this: <?php echo do_shortcode(“[metaslider id=36]”); ?> This of course suppose that you have the plugin activated and a slider created with an ID = 36. I hope … Read more
The theme editor is not available on multisite installations. Changing this would require modifications to WordPress Core, that would need to be remade everytime you updated WordPress. I STRONGLY advise against this. Also keep in mind that if one user edits a theme, everyone else using that theme gets the changes. There is only one … Read more
I do not think this is technically feasible. In general case any plugin creating its own admin screens will be relying on admin-side conditionals (such is_admin()) and context (such as $hook_suffix, etc). Reproducing this in general at the front side will be fragile and nightmare. Simply put creating custom curated interfaces has little to do … Read more
I do not know this theme. But you must use this two functions somewhere: get_theme_mod (‘background_image’, $default); set_theme_mod (‘background_image’, $_category_image_absolute_path); Maybe, you can define new modification names with this functions. For example, ‘backgroud_image_entertainment’, ‘background_image_storysode’, etc. (as is shown in the referred web page) by using set_theme_mod. set_theme_mod (‘backround_image_entertainment’, $_category_image_absolute_path); Then, you should add some functions … Read more
Finally figured it out. Using the plugin mentioned above (linked here for ease) and the basics of the answer to this question I was able to cobble together this code It’s a bit hamfisted, I’ll admit that (mainly replacing the preg_match with strstr) but it got the job done. I’m open to any improvements you … Read more
You are looking for get_blog_details function. $blog_details = get_blog_details( $blog_id ); Here is the official documentation.
Setting display_errors to 1 has let me determine that for some reason wp-includes/pluggable.php was not included while running the plugin, so wp_get_current_user() function was missing. Although I didn’t find the reason of malfunction, thanks to answer to this question I hardcoded plugin by setting following at the beginning: if(!function_exists(‘wp_get_current_user’)) { include(ABSPATH . “wp-includes/pluggable.php”); } Now … Read more
You can use the filter template_include. wp-includes/template-loader.php is where template is included.
