After digging in the setting API I found the answer. Method 1 was correct, but the notification should not be done by hooking to admin_notices, rather by the function add_settings_error add_action (‘pre_update_option_my_var’, function( $new_value, $old_value) { //Do my validation $valid = ( ‘correct_value’ == $new_value ); if ( !$valid ) { //This fixes the issue … Read more
If you look at do_settings_fields() (line 1125, /wp-admin/includes/template.php), you can see that the table information is hardcoded into the the settings API. If you wish to not use the table, you will need to develop your own settings functions.
I dont know if it is possible to add a new field directly under the “Posts page” dropdown field, atleast I found no way to do this. But you could just add another dropdown menu to the reading settings page. This will be on the bottom thou. To do this, first we need to register … Read more
Here’s an updated version of your original code, which solves the saving issue. The reason that the content inside of the WP Editor was not saving was due to the value of the textarea_name parameter passed to wp_editor(). This is wrong: ‘textarea_name’ => ‘pw_intro’, It should look like this: ‘textarea_name’ => ‘pw_settings[pw_intro]’, I also removed … Read more
You’re absolutely right that you can pass reusable form field markup to add_settings_field(). The trick is to define the data type for each setting, and then pass the same callback to each call to add_settings_field(). Within that callback, you simply add a switch that includes cases for each data type. Here’s how I do it … Read more
Try this. Please change the field name with yours <?php class MySettingsPage { /** * Holds the values to be used in the fields callbacks */ private $options; /** * Start up */ public function __construct() { add_action( ‘admin_menu’, array( $this, ‘add_plugin_page’ ) ); add_action( ‘admin_init’, array( $this, ‘page_init’ ) ); } /** * Add … Read more
There is not much to it, really. During the loading of WordPress engine wp-settings.php file is processed. Among other things this files calls wp_get_active_and_valid_plugins() function, that gets list of activated (through admin interface) plugins from active_plugins option (stored in database). For each active plugin its main file (the one holding plugin header) is included and … Read more
if ( get_option( ‘my_setting’ ) === false ) // Nothing yet saved update_option( ‘my_setting’, ‘default_stuff’ );
If the setting in question is $setting, and is a checkbox type, you validate it like so: <?php $valid_input[$setting] = ( isset( $input[$setting] ) && true == $input[$setting] ? true : false ); ?> In this case, $input is the form data passed to the validation callback, where $input is an array-of-arrays. The validation method … Read more
Instead of using add_settings_section() and add_settings_field() every time, create a function that returns an array of options for example: function my_theme_options() { $options = array(); $options[] = array( ‘id’ => ‘ID’, ‘title’ => ‘Title’, ‘type’ => ‘text_field’, // use this value to sanitize/validate input ‘validate’ => ‘url’ // use this value to validate the text … Read more
