Metabox field in Wordpress admin menu is not saved
I created a special menu called price list on the WordPress admin page. I have custom metabox area on this menu page. I also have reproducible input elements. Everything seems to be fine, just the data is not being saved. I'm stuck at this stage. Please can someone help me with this? This is my code that creates a menu and metabox on the admin page:
<?php function register_pricepage_subpage() {
add_menu_page( 'Custom Price List Page', 'Dynamic Price List', 'manage_options', 'dynamic-price-list', 'price_page_meta_box_display' );
add_action( 'admin_init', 'register_pricepage_settings' );
}
add_action( 'admin_menu', 'register_pricepage_subpage' );
function register_pricepage_settings() {
register_setting( 'pricepage-settings-group', 'name[]' );
register_setting( 'pricepage-settings-group', 'price[]' );
}
function price_page_meta_box_display($post) {
global $post;
$price_page_fields = get_post_meta(isset($post->id), 'price_page_fields', true);
wp_nonce_field( 'price_page_meta_box_nonce', 'price_page_meta_box_nonce' );
?>
<script type="text/javascript">
jQuery(document).ready(function($) {
$('#add-row').on('click', function() {
var row = $('.empty-row.screen-reader-text').clone(true);
row.removeClass('empty-row screen-reader-text');
row.insertBefore('#price_page-fieldset-one tbody>tr:last');
return false;
});
$('.remove-row').on('click', function() {
$(this).parents('tr').remove();
return false;
});
});
</script>
<form method="post" action="options.php">
<?php
settings_fields( 'pricepage-settings-group' );
do_settings_sections( 'pricepage-settings-group' );

Solution
I just shared sample code to save the custom fields. You can modify whatever you want.
function register_pricepage_subpage() {
add_menu_page( 'Custom Price List Page', 'Dynamic Price List', 'manage_options', 'dynamic-price-list', 'price_page_meta_box_display' );
add_action( 'admin_init', 'register_pricepage_settings' );
}
add_action( 'admin_menu', 'register_pricepage_subpage' );
function register_pricepage_settings() {
// register_setting( 'pricepage-settings-group', 'name[]' );
// register_setting( 'pricepage-settings-group', 'price[]' );
if ( isset( $_POST['name'] ) && isset( $_POST['price'] ) ){
// print_r($_POST);
// return;
// if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
// return;
// if (!current_user_can('edit_post', $post_id))
// return;
$old = get_option( 'price_page_fields' );
$new = array();
$names = $_POST['name'];
$prices = $_POST['price'];
$count = count( $names );
for ( $i = 0; $i < $count; $i++ ) {
if ( $names[$i] != '' ) :
$new[$i]['name'] = stripslashes( strip_tags( $names[$i] ) );
if ( $prices[$i] == ' ' )
$new[$i]['price'] = '';
else
$new[$i]['price'] = stripslashes( $prices[$i] );
endif;
}
if ( !empty( $new ) && $new != $old ){
update_option( 'price_page_fields', $new );
//update_post_meta( $post_id, 'price_page_fields', $new );
}elseif ( empty($new) && $old ){
//delete_post_meta( $post_id, 'price_page_fields', $old );
}
}
}
function price_page_meta_box_display($post) {
// global $post;
// $price_page_fields = get_post_meta(isset($post->id), 'price_page_fields', true);
wp_nonce_field( 'price_page_meta_box_nonce', 'price_page_meta_box_nonce' );
$price_page_fields = get_option( 'price_page_fields' );
?>
