The question:
I’ve this code:
/* Hook to admin_menu the yasr_add_pages function above */
add_action('admin_menu', 'yasr_add_pages');
function yasr_add_pages()
{
//Add Settings Page
add_options_page(
'Yet Another Stars Rating: Settings', //Page Title
__('Yet Another Stars Rating: Settings', 'yasr'), //Menu Title
'manage_options', //capablity
'yasr_settings_page', //menu slug
'yasr_settings_page_content' //The function to be called to output the content for this page.
);
}
/* Settings Page Content */
function yasr_settings_page_content()
{
if (!current_user_can('manage_options')) {
wp_die(__('You do not have sufficient permissions to access this page.', 'yasr'));
}
include(YASR_ABSOLUTE_PATH . '/yasr-settings-page.php');
} //End yasr_settings_page_content
and, this is the content in yasr-settings-page:
<div class="wrap">
<h2>Settings API Demo</h2>
<form action="options.php" method="post">
<?php
settings_fields( 'yasr_multi_form' );
do_settings_sections( 'yasr_settings_page' );
submit_button( 'Salva' );
?>
</form>
</div>
<?php
add_action( 'admin_init', 'yasr_multi_form_init' );
function yasr_multi_form_init() {
register_setting (
'yasr_multi_form', // A settings group name. Must exist prior to the register_setting call. This must match the group name in settings_fields()
'yasr_multi_form_data' //The name of an option to sanitize and save.
);
add_settings_section( 'yasr_section_id', 'Gestione Multi Set', 'yasr_section_callback', 'yasr_settings_page' );
add_settings_field( 'yasr_field_name_id', 'Nome Set', 'yasr_nome_callback', 'yasr_settings_page', 'yasr_section_id' );
}
function yasr_section_callback() {
echo "Descrizione sezione";
}
function yasr_nome_callback() {
$option = get_option( 'yasr_multi_form_data' );
$name = esc_attr( $option['name'] );
echo "<input type='text' name='yasr_multi_form_data[name]' value='' />";
}
The settings page output settings_field
function (I can see the input type hidden on my source) and the submit button, but I can’t render the do_settings_section
and I really can’t understand why. Any suggestions?
The Solutions:
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
Method 1
From what I see, you are mixing output and the code, which is meant to prepare that output. More, the preparation is coming after the output started. Looks weird to me.
Here I updated your code, and it works OK:
/* Hook to admin_menu the yasr_add_pages function above */
add_action( 'admin_menu', 'yasr_add_pages' );
function yasr_add_pages() {
//Add Settings Page
add_options_page(
'Yet Another Stars Rating: Settings', //Page Title
__( 'Yet Another Stars Rating: Settings', 'yasr' ), //Menu Title
'manage_options', //capability
'yasr_settings_page', //menu slug
'yasr_settings_page_content' //The function to be called to output the content for this page.
);
}
add_action( 'admin_init', 'yasr_multi_form_init' );
function yasr_multi_form_init() {
register_setting(
'yasr_multi_form', // A settings group name. Must exist prior to the register_setting call. This must match the group name in settings_fields()
'yasr_multi_form_data' //The name of an option to sanitize and save.
);
add_settings_section( 'yasr_section_id', 'Gestione Multi Set', 'yasr_section_callback', 'yasr_settings_page' );
add_settings_field( 'yasr_field_name_id', 'Nome Set', 'yasr_nome_callback', 'yasr_settings_page', 'yasr_section_id' );
}
function yasr_section_callback() {
echo "Descrizione sezione";
}
function yasr_nome_callback() {
$option = get_option( 'yasr_multi_form_data' );
$name = esc_attr( $option['name'] );
echo "<input type='text' name='yasr_multi_form_data[name]' value='' />";
}
/* Settings Page Content */
function yasr_settings_page_content() {
if ( ! current_user_can( 'manage_options' ) ) {
wp_die( __( 'You do not have sufficient permissions to access this page.', 'yasr' ) );
}
?>
<div class="wrap">
<h2>Settings API Demo</h2>
<form action="options.php" method="post">
<?php
settings_fields( 'yasr_multi_form' );
do_settings_sections( 'yasr_settings_page' );
submit_button( 'Salva' );
?>
</form>
</div>
<?php
} //End yasr_settings_page_content
Method 2
So the problem here isn’t actually anything to do with the way you are registering settings or outputting them. What I found it came down to was a mistiming on the order of actions.
Try making a file to hold all of your settings code and call that file with an action of ‘init’. The ‘admin_init’ action you are calling is correct, but it is just that it is being called after the admin_init has already been run.
