Implement toggle switch for theme options in settings API
There are several ways to implement an options page. You can implement a quick and easy options page via Advanced Custom Fields Pro (find out more here: https://www.advancedcustomfields.com/resources/options-page/) To do things the WordPress way(without the help of plugins), you will want to follow this guide here: https://developer.wordpress.org/plugins/settings/custom-settings-page/ Once implemented, you should be able to save … Read more
Callback is not called in add_settings_field() when passed as part of an array, but recognises that it’s there. It’s passed Class to Class using OOP
From what I could see, the problem is not with the field callback, but it’s the section ID whereby you’re setting it to default — see $field[“section”] = ‘default’ below: // In the foreach in AddSettings.php add_settings_field( $field[“id”], $field[“title”], isset( $field[“callback”] ) ? $field[“callback”] : “”, $field[“page”], $field[“section”] = ‘default’, $field[“args”] = array() ); So … Read more
Single sanitization callback for multiple fields
How can I have a single sanitization callback for multiple fields and then access the values of it ($input)? For fields with the same validation logic, just set sanitize_callback to the same callback, e.g. if field_1 and field_2 are single-line and text-only fields (i.e. no HTML allowed), you can use ‘sanitize_callback’ => ‘sanitize_text_field’ for both … Read more
The Settings API – What is the purpose of default value in register_setting?
Excerpt from the register_setting() documentation: ‘default’ (mixed) Default value when calling get_option(). So the purpose of the default argument is to provide a default value which get_option() would return if the option does not exist (or has not yet been saved) in the database. And register_setting() sets the option’s default value via filter_default_option() which is … Read more
Settings API and dynamically generated submenu pages
I think the approach you’re attempting is prohibitively complex, and will not scale well at all. I would suggest two possible alternatives to the approach you’re trying to take: Create a Widget to display your Plugin output, so that the Widgets API handles the settings for multiple instances of your Plugin output. Create a Shortcode … Read more
Storage of array in settings
Since the layout names are dynamic, perhaps it’s better to store them in a numerically indexed nested array? Something like: wpv_settings[layouts][0][name] = $key wpv_settings[layouts][0][markup] = $value wpv_settings[layouts][1][name] = $key wpv_settings[layouts][1][markup] = $value …etc?
wp_update_nav_menu_item not saving in multisite API
$wpdb->insert( $wpdb->term_relationships, array( “object_id” => $thisMenuItem, “term_taxonomy_id” => $menuID ), array( “%d”, “%d” ) ); This was missing from the Question code. It allows the menu items to bind to the navigation menu itself.
How can I insert some extra validation into the theme options’ validation function using add_filter?
You want to manipulate and return the same input you have coming into the function. In your case that is $input. That is how filters work. function add_validation( $input ) { // here I want to add some validation for a simple field named ‘example’ if ( isset( $input[‘example’] ) && !empty( $input[‘example’] ) ) … Read more
Settings API in Section
Here you go my friend: add_filter( ‘admin_init’ , ‘register_fields’ ); function register_fields() { register_setting( ‘general’, ‘msp_duration’, ‘esc_attr’ ); add_settings_field( ‘msp_duration’, __(‘Cache Duration’) ,’fields_html’, ‘general’ ); } function fields_html() { $value = get_option( ‘msp_duration’ ); $fields = array( array( “name” => __(‘Every 6 hours’), “value” => 60 * 60 * 6, ), array( “name” => __(‘Every … Read more
