我需要更新ID下拉列表「arome0」時,選擇與簡碼[brand_list產生的第一個值]。
我需要使用Ajax才能獲得品牌的子項並填充「arome0」下拉列表。
我創建了這個jquery代碼,當我的第一個下拉列表的值發生變化時調用。
//On selected brand, update flavors list
$(document).on('change', "select[id^='marque']", function() {
var $brandid = $(this).val();
var $brand_dd_id = $(this).attr('id');
var $flav_dd_id = $brand_dd_id.substr($brand_dd_id.length-1);
$("#arome"+$flav_dd_id).empty();
//Make AJAX request, using the selected value as the GET
$.ajax({
type: 'GET',
data: '{"parent_id":"' + $brandid + '"","id":"'+ $flav_dd_id +'",action":"brand_children"}',
success: function(output) {
$("#arome"+$flav_dd_id).html(output);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status + " "+ thrownError);
}});
});
在我的functions.php
我添加了這個:
add_action('wp_ajax_brand_children', 'GetBrandChildren');
add_action('wp_ajax_nopriv_brand_children', 'GetBrandChildren');
function GetBrandChildren($parent_id,$id) {
$children = wp_dropdown_pages(array('id'=>'arome$id','post_type'=>'aromes-type','child_of'=>$parent_id,'echo'=>0));
return $children;
}
,但它不工作,我的事情有一個與數據的問題返回。 有什麼想法?
感謝
UPDATE:
它現在的工作,最終的問題是下拉不與父帖子的ID正確篩選。也許我沒有正確使用wp_dropdown_page。
更新的functions.php:
add_action('wp_ajax_brand_children', 'GetBrandChildren');
add_action('wp_ajax_nopriv_brand_children', 'GetBrandChildren');
function GetBrandChildren() {
$parent_id = $_POST['parent_id'];
$id = $_POST['id'];
echo wp_dropdown_pages(array("id"=>"arome$id",'post_type'=>'aromes-type','child_of'=>$parent_id,'echo'=>0));
//ob_clean();
//echo "working";
wp_die();
}
// need these two lines to be ale to locate the admin-ajax.php inside jquery
wp_enqueue_script('my-ajax-request', get_template_directory_uri() . '/js/ajax.js', array('jquery'));
wp_localize_script('my-ajax-request', 'MyAjax', array('ajaxurl' => admin_url('admin-ajax.php')));
更新的JQuery:
//On selected brand, update flavors list
$(document).on('change', "select[id^='marque']", function() {
var $brandid = $(this).val();
var $brand_dd_id = $(this).attr('id');
var $flav_dd_id = $brand_dd_id.substr($brand_dd_id.length-1);
$("#arome"+$flav_dd_id).empty();
//Make AJAX request, using the selected value as the GET
//var ajax_url = admin_url('admin-ajax.php');
$.ajax({
url: MyAjax.ajaxurl,
data: {
'parent_id': $brandid,
'id': $flav_dd_id,
'action': 'brand_children'
},
success: function(output) {
console.log(output);
$("#arome"+$flav_dd_id).html(output);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status + " "+ thrownError);
}});
});
最後一個問題是wp_dropdown_pages不與父ID過濾,也許我沒有正確地使用它。
您可以在瀏覽器中查看開發者控制檯,看到很多情況。具體來說,你可以看到網絡調用和響應,看看頁面發送到服務器和服務器發回的數據/信息 – 2015-02-05 23:41:21
(array('id'=>'arome $ id'是錯的,你不是正確地轉義字符串try(array(「id」=>「arome $ id」 – 2015-02-05 23:51:47
我對'id'進行了修改,但它仍然無法正常工作,當我查看控制檯時,我看到了對admin-ajax的調用。 PHP的200返回碼,還有什麼我可以看看? – 2015-02-06 00:38:02
