It appears that the options-reading.php file is hard-coding its options, rather than using the Settings API. And that option is using wp_dropdown_pages() specifically. The Codex lists the following arguments for wp_dropdown_pages(): <?php $args = array( ‘depth’ => 0, ‘child_of’ => 0, ‘selected’ => 0, ‘echo’ => 1, ‘name’ => ‘page_id’); ?> The Codex page also … Read more
As background, and to answer my own question (after some research), the <form> tag in an Options screen is usually generated with code similar to this: <form action=’options.php’ method=’post’> <?php settings_fields( ‘pluginPage’ ); // initializes all of the settings fields do_settings_sections( ‘pluginPage’ ); // does the settings section; into a table submit_button(); // creats the … Read more
Fetch current options, and be sure to return an array if empty: $current_options = get_option( ‘option_name’, array() ); Ensure desired options are in an array: $desired_options = array( /* whatever you need goes here */ ); Merge them, using [wp_parse_args()]1: $merged_options = wp_parse_args( $current_options, $desired_options ); Update update_option( ‘option_name’, $merged_options ); Of course, the trick … Read more
Managed to fix this by doing the following: function dat_checkbox_field_0_render( ) { $options = get_option( ‘dat_settings’ ); $a = $options; if (array_key_exists(“dat_checkbox_field_0″,$a)) { } else { $options[‘data_checkbox_field_0’] = false; } ?> <input type=”checkbox” name=”dat_settings[dat_checkbox_field_0]” <?php checked( $options[‘dat_checkbox_field_0’], 1 ); ?> value=”1″> <?php }
The field name should be uwcc_settings[uwcc_checkbox_field_1][], i.e. turn the field into an array. Secondly, when saved as an array, you should use in_array() along with the checked() function. But first, let’s put the uwcc_checkbox_field_1 option’s values into a variable: $uwcc_checkbox_field_1 = isset( $options[‘uwcc_checkbox_field_1’] ) ? (array) $options[‘uwcc_checkbox_field_1’] : []; Now you call checked() like so … Read more
The reason is that if you are on page 1, the data that is posted to be saved is an array of the form: XX_theme_settings=array(‘XX_Option1′ =>’input1′,’XX_Option2’=>’input2′,…) and contains no data from page 2. This is because the input from page 2 is not posted with it (since it wasn’t in the same <form> – it’s … Read more
I am not exactly sure what you mean by saying that you can see your settings section and fields displayed correctly, but your my_plugin_settings has not been created. I know sometimes I forget to add the actual admin part in which generally looks something like this: settings_fields( ‘my_plugin_settings’ ); do_settings_sections( ‘my_plugin_settings’ ); submit_button(); Or is … Read more

With this feature, you can backup all options to another place, that you … Read more
The callback you have given in add_menu_page() is a static function, not a class method. It should be: add_menu_page( ‘School Manager Settings’, ‘School Manager’, ‘administrator’, ‘school-manager-settings’, array ( $this, ‘show_admin_settings_page’ ) ); And please don’t use &$this anymore, that’s PHP 4. 🙂 My demo plugin T5 Admin Menu Demo might help understanding how that works.
The easiest way would be to look at the code of Si Contact Form (since it already does what you want) and use the same kind of system. Shortly, you’ll need methods to do the following: Create an XML (or other format) document of your theme options. Save/Export the XML document. Import the XML document … Read more
