I finally got it to work after a long time of trying to figure this out! Credit to Samuel Elh for helping me, http://sam.elegance-style.com/ This is useful if anyone wants to allow users to make small style changes to a theme. Rather than create many child themes, if you just need some stylesheet overrules to … Read more
This should do it: // Going to add a conditional statement here to run this vc_remove_element function if the checkbox for Row is selected vc_remove_element( “vc_row” ); // Row add_action(‘admin_menu’, ‘plugin_admin_settings_tab’); function plugin_admin_settings_tab() { add_options_page(‘Remove Visual Composer Elements’, ‘Remove Visual Composer Elements’, ‘manage_options’, ‘remove_visual_composer_elements’, ‘plugin_rvce_options_page’); add_action(‘admin_init’, ‘plugin_rvce_admin_init’); } ?> <?php function plugin_rvce_options_page() { ?> <div> … Read more
Looks like your validation argument is negative. if ($foo != “”) { //means if foo not equal to empty space // do something when not empty // here you are setting an error } else { // do something when empty // here you are trying to do your normal operation } You are setting … Read more
All options are loaded at pageload, because they include not only plugin/theme options, but also WP native stuff, like menus and widgets. Distinguishing between which ones to (not) load based on whether they are needed would take quite some calculations, so the performance issue you refer to doesn’t exist. Now about the extensibility. Let’s take … Read more
If you check the implementation of get_option() you’ll see that in line 168 it calls wp_cache_get() like so: $value = wp_cache_get( $option, ‘options’ ); This means multiple calls to get_option(“style_settings”) within the same PHP execution will be served from cache. There is no need to re-invent this, as you might break other functionality with it. … Read more
First kick in your validation callback by changing the register_setting() to register_setting( ‘pluginname_options’, ‘pluginname-settings’, ‘pluginname_validate’ ); And then update your validation function to actually do something. Below it gets the current state of the options, and then only updates the pieces of the array that are submitted. When you are on a tab and click … Read more
You could use /wp-admin/admin-post.php. Link: $url = admin_url( ‘admin-post.php?action=somethingunique’ ); print “<a href=”https://wordpress.stackexchange.com/questions/85825/$url”>Update and redirect</a>”; Then you should register a callback for that action: add_action( ‘admin_post_somethingunique’, ‘wpse_85825_callback’ ); And in that callback you can do what you want: function wpse_85825_callback() { if ( current_user_can( ‘manage_options’ ) ) update_option( ‘my_option’, ‘some_value’ ); wp_redirect( admin_url( ‘users.php’ ) … Read more
When referring to urls within the network-admin, you should consider the network_admin_url(). core function, that falls back to admin_url() for non-multisite setups. So try this, using add_query_arg just as @toscho uses in the answer OP links to: echo esc_url( add_query_arg( ‘action’, ‘your_option_name’, network_admin_url( ‘edit.php’ ) ) ); instead of hard-coding it with possible wrong assumptions … Read more
The option will be stored in the table $wp_prefix . “options” as an array. You can get the option with $myoptions = get_option(‘plugin_options’); try var_export( $myoptions ); to see that. There is also a hidden page in wp-admin/options.php where you can see all saved options.
You need to save the version to the database– aka. save it “as an option”– so that your script has a comparison case. That is, your script should… Check the database for a version number Compare that version number to the new version number– a variable or constant in your plugin file. Update things if … Read more
