In a nutshell you cannot literally do this. For plugins and themes WordPress erases whole folder on update and unpacks full folder with new version in its place. You could emulate it by temporarily moving folder away and back, but that is inherently faulty solution. Extension folders are essentially not meant to contain content in … Read more
Got it. This post demonstrates what I need.
You’ll have to use get- and add_option inside a register_activation_hook. <?php register_activation_hook(__FILE__,’save_activation_timestamp’); function save_activation_timestamp() { add_option(“myplugin_activation_timestamp”,mktime()); } ?> You can find an entire tutorial on that at CodeYoghurt. It even mentions your case as an example.
The Problem This turned out to be a common case of needing to use stripslashes();. How did I figure this out? I logged into phpMyAdmin, navigated to the options table, found my option name, and edited it. Here’s what I discovered… s:11:”description”;s:90:”<span style=\”text-decoration: underline;\”>This is supposed to be underlined text.</span>”; So obviously my plugin is … Read more
Couple things I’d try: I’ve seen weird behavior with plugins in general when WP isn’t given enough memory. You might want to up PHP and WordPress’ memory limit and see if you still get that weird behavior. WP Cron only runs on a page load so between 4:05 and 4:07 (or whenever you’re getting the … Read more
First, let me say that you are wrong saying that the function works if you use outside a class. That is not correct and you can verify using this (it is the exact method of your class written and executed as function: //Define the function function xenword_add_wp_user() { /** * @since 1.0.6 * Insert the … Read more
What you need is the function_exists method you would use it like this when defining your returnJs function: if( ! function_exists(‘returnJs’) ){ function returnJs(){ //Code goes here } } However, better practice would be to just define the returnJs function in your plugin
You shouldn’t put quotes around the index for HTML names – otherwise you end up with ‘single_images’ (including single quotes) as the PHP name (so you’d have to address it $iwmp_options[“‘single_images'”], which some might consider confusing) … eg: add_action( ‘admin_init’, function () { register_setting( ‘iwmp_settings’, ‘iwmp_settings’ ); add_settings_section( ‘single_images’, __( ‘Single Images’, ‘iwmp_domain’ ) , … Read more
One option is to use the Debug bar plugin and the Debug Bar Actions and Filters Addon
prepare() is used to escape the values for example in the WHERE-statement. Usually it is anticipated the table selection is “hardcoded”. If you can’t use for example $wpdb->posts or the other “table”-functions, you could whitelist the allowed tables and check if $table_name is on this white list: <?php $allowed_tables = array( $wpdb->prefix . ‘nametbl’, $wpdb->prefix … Read more
