For adding a new tab in the Package Settings metabox, you can try the below code in your theme functions.php file,
// Add custom tab
add_filter('wpdm_package_settings_tabs', 'add_custom_package_tab');
function add_custom_package_tab($tabs) {
$tabs['custom_tab'] = array(
'name' ► 'Custom Settings', // Tab label
'callback' ► 'custom_tab_callback' // Function to render tab content
);
return $tabs;
}
// Callback function to display tab content
function custom_tab_callback() {
global $post;
// Get saved values
$custom_field = get_post_meta($post->ID, '__wpdm_custom_field', true);
?>
<div class="w3eden">
<table class="table table-bordered">
<tr>
<td width="150px">Custom Field:</td>
<td>
<input type="text"
class="form-control input-sm"
name="file[custom_field]"
value="<?php echo esc_attr($custom_field); ?>" />
</td>
</tr>
<!-- Add more fields as needed -->
</table>
</div>
<?php
}
// Save custom field values
add_action('save_post', 'save_custom_tab_data');
function save_custom_tab_data($post_id) {
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return;
// Save custom field
if (isset($_POST['file']['custom_field'])) {
update_post_meta($post_id, '__wpdm_custom_field',
sanitize_text_field($_POST['file']['custom_field'])
);
}
}
Please kindly check and let me know if it works for you.
Thank you and regards
