How to create custom item in menu
-
(file: nav-menus.php)
I want to attach images to items, and then get items using filter, like this:function wpse19375_nav_class( $classes, $item ){ if( in_array( 'current-menu-item', $classes ) ) { get_post_meta($item->ID, 'custom_image_data_' . $item_id, true); } return $classes; } add_filter( 'nav_menu_css_class', 'wpse19375_nav_class', 10, 2 );
I have problem with upload images
1)If I come to the page then page (nav-menus.php) have error because $_REQUEST[‘menu’] is empty and I cannot get current nav menu ID
2)I cannot make js script for every item, I try to use loop but get a lot of errorfunctions.php
Problem:
– $menuItems = wp_get_nav_menu_items($_REQUEST[‘menu’]);
– wp_localize_script(
‘wp_img_upload’,
‘customUploads_’ . $items_id[$i],
array(
‘imageData’ => get_post_meta($items_id[$i++],
‘custom_image_data_’ . $items_id[$i],
true ) ) );function register_admin_script() { $menuItems = wp_get_nav_menu_items($_REQUEST['menu']); $items_id; $i = 0; wp_enqueue_script( 'wp_img_upload', CURRENT_DIR_URL . '/include/uploader.js', array('jquery', 'media-upload'), '0.0.1', true ); foreach ($menuItems as $currentItem) { $items_id[$i] = $currentItem->ID; wp_localize_script( 'wp_img_upload', 'customUploads_' . $items_id[$i], array( 'imageData' => get_post_meta($items_id[$i++], 'custom_image_data_' . $items_id[$i], true ) ) ); } wp_localize_script( 'wp_img_upload', 'currentItemsID', array('itemsID' => $items_id)); wp_enqueue_media(); } add_action( 'admin_enqueue_scripts', 'register_admin_script' );
uploader.js
Problem: I cannot make js script for every itemvar addButton = document.getElementById( 'image-upload-button_' + currentItemsID.itemsID[0] ); var deleteButton = document.getElementById( 'image-delete-button_' + currentItemsID.itemsID[0] ); var img = document.getElementById( 'image-tag_' + currentItemsID.itemsID[0] ); var hidden = document.getElementById( 'img-hidden-field_' + currentItemsID.itemsID[0] ); var customUploader = wp.media({ title: 'Select an Image', button: { text: 'Use this Image' }, multiple: false }); addButton.addEventListener( 'click', function() { if ( customUploader ) { customUploader.open(); } } ); customUploader.on( 'select', function() { var attachment = customUploader.state().get('selection').first().toJSON(); img.setAttribute( 'src', attachment.url ); hidden.setAttribute( 'value', JSON.stringify( [{ id: attachment.id, url: attachment.url }]) ); toggleVisibility( 'ADD' ); } ); deleteButton.addEventListener( 'click', function() { img.removeAttribute( 'src' ); hidden.removeAttribute( 'value' ); toggleVisibility( 'DELETE' ); } ); var toggleVisibility = function( action ) { if ( 'ADD' === action ) { addButton.style.display = 'none'; deleteButton.style.display = ''; img.setAttribute( 'style', 'width: 100%;' ); } if ( 'DELETE' === action ) { addButton.style.display = ''; deleteButton.style.display = 'none'; img.removeAttribute('style'); } }; window.addEventListener( 'DOMContentLoaded', function() { if ( "" === customUploads.imageData || 0 === customUploads.imageData.length ) { toggleVisibility( 'DELETE' ); } else { img.setAttribute( 'src', customUploads.imageData.src ); hidden.setAttribute( 'value', JSON.stringify([ customUploads.imageData ]) ); toggleVisibility( 'ADD' ); } } );
The files below have no problem
