Admin Ajax返回0

所以我解决了.尽管我进行了改进,但并不是jQuery这样,而是回调函数的位置.我将其移至主插件文件,并且可以正常工作.

So I worked it out. It was not the jQuery as such though I have improved that, it was the placement of the call back function. I moved it over to the main plugin file and it worked.

0响应意味着未设置动作(在ajax数据中)或找不到该动作的回调函数.

A 0 response means either that the action is not set (in the ajax data) or that the action's callback function cannot be found.

您要做的是在函数的末尾添加die();.

在此处查看原因和更多信息: http://codex.wordpress.org/AJAX_in_Plugins

注意:

• 在执行echo之前,您应该die.这样可以防止服务器错误,并且在调试时会有所帮助.

What you have to do is add die();at the end of your function.

See the reason and more here: http://codex.wordpress.org/AJAX_in_Plugins

Notes:

• You should echo something before executing die. This will prevent server errors, and will help when debugging.

我遇到了同样的问题.并解决了.您必须像示例中一样发送" action"变量:

 var dataString = {lat: '55.56', lng: '25.35', action:'report_callback'};
 $.ajax({                            
        url: "http://domain.net/wp-admin/admin-ajax.php",  
        type: "POST",
        //some times you cant try this method for sending action variable
        //action : 'report_callback',
        data:dataString,        
        success: function(data){ 
            console.log(data);

            },
        error: function() {
            console.log("Error");            
        }
    });
 

因为在wp-admin/admin-ajax.php中是操作变量的处理程序:

 if ( empty( $_REQUEST['action'] ) ) {...}
Line 26
 

I got same problem. And solved it. You must send "action" variable like in example:

var dataString = {lat: '55.56', lng: '25.35', action:'report_callback'};
 $.ajax({                            
        url: "http://domain.net/wp-admin/admin-ajax.php",  
        type: "POST",
        //some times you cant try this method for sending action variable
        //action : 'report_callback',
        data:dataString,        
        success: function(data){ 
            console.log(data);

            },
        error: function() {
            console.log("Error");            
        }
    });

Because in wp-admin/admin-ajax.php is handler for action variable:

if ( empty( $_REQUEST['action'] ) ) {...}
Line 26

我也有这个问题,这是我在PHP函数中使用return而不是echo的事实.将其更改为echo即可解决.

 function doAjax() {
    $result = getPosts();
    echo json_encode($result, true);
    die();
}
 

I had this problem too, and it was the fact that I was using return instead of echo in my PHP function. Changing it to echo fixed it.

function doAjax() {
    $result = getPosts();
    echo json_encode($result, true);
    die();
}

尝试在控制台上运行此代码

 jQuery.post(ajaxurl, {action:'cleanlinks_ajax_get_post_data'}, function(response) {
     console.log (response);
});
 

我发现您的JavaScript代码有很多错误,这可能就是原因.

Try running this code on the console

jQuery.post(ajaxurl, {action:'cleanlinks_ajax_get_post_data'}, function(response) {
     console.log (response);
});

I can see many things wrong about your JavaScript code and that might be the reason.

我遇到了同样的问题,要解决该问题,我使用了 wp_die() 在函数的末尾,仅在echo之后.不要忘记对脚本进行操作.

可以肯定的是,请检查您的函数是否必须使用 wp_ajax_nopriv ,例如wp_ajax.

I had the same problem, to fix it I used wp_die() at the end of my function just after an echo. Don't forget to pass your action on your script.

To be sure, check if your function has to use wp_ajax_nopriv like wp_ajax.

仅供参考,对于任何在这里谷歌搜索" ajax请求返回0"的人: 请记住,当您向对象的方法添加ajax操作时,请确保方法访问修饰符为public.

 add_action( 'wp_ajax_my_action', [$object, 'my_method']);
 

add_action无法在$object之外调用您的方法,它只会静音.

Just for reference, for anyone who get here googling "ajax request is returning 0": Remember when you add ajax action to object's method to be sure methods access modifier is public.

add_action( 'wp_ajax_my_action', [$object, 'my_method']);

add_action just silences if it can't call your method outside of $object.

如果您不使用wp_localize_script()函数设置ajax url,则admin ajax将返回0.我认为这是Wordpress错误.这是一个示例:

     wp_enqueue_script( 'search_js', get_template_directory_uri() . '/js/search.js', array( 'jquery' ), null, true );    
    wp_localize_script( 'search_js', 'ajaxurl', admin_url( 'admin-ajax.php' ) );
 

javascript文件(search.js):

     $('#search_input').autocomplete({
    source: function(request, response) {

        $.ajax({
            type: 'POST',
            dataType: 'json',
            url: ajaxurl,
            data: 'action=my_custom_action_search&search_criteria=' + request.term,
            success: function(data) {
                response(data);
            },
            error: function(errorThrown){
                console.log(errorThrown);
            } 
        });
    },
    minLength: 3
});
 

If you don't use wp_localize_script() function to set ajax url, admin ajax returns 0. I think it's Wordpress bug. Here's is an example :

    wp_enqueue_script( 'search_js', get_template_directory_uri() . '/js/search.js', array( 'jquery' ), null, true );    
    wp_localize_script( 'search_js', 'ajaxurl', admin_url( 'admin-ajax.php' ) );

The javascript file (search.js) :

    $('#search_input').autocomplete({
    source: function(request, response) {

        $.ajax({
            type: 'POST',
            dataType: 'json',
            url: ajaxurl,
            data: 'action=my_custom_action_search&search_criteria=' + request.term,
            success: function(data) {
                response(data);
            },
            error: function(errorThrown){
                console.log(errorThrown);
            } 
        });
    },
    minLength: 3
});

 jQuery(document).ready(function(){
    jQuery('.cl_link_buttons').val('id').click(function() {
       $.ajax({
            type:'POST',
            url: ajaxurl,
            data: {
                action : 'ajax_filter',
                currentid : 'currentid'
            },
            success: function (result) {
                console.log(result);
                $result = $(result);
                        $result.fadeIn('7000');
                        $("#showresults").html(result);

            },
            error: function (xhr, status) {
                alert("Sorry, there was a problem!");
            },
            complete: function (xhr, status) {
                $('#showresults').slideDown('slow')
            }

那些得到错误0的人:),action=>'action'

 var data = { 'action': 'firmabilgilerikaydet', 'data': form_data };

$.post(ajaxurl, data, function(response) { alert(response); });
 

Those who get error 0 :), action => 'action'

var data = { 'action': 'firmabilgilerikaydet', 'data': form_data };

$.post(ajaxurl, data, function(response) { alert(response); });

如果您使用的是本地主机,并且您的php服务器端代码位于插件文件中,请首先登录管理控制台并刷新插件页面.其次,检查插件是否已激活.然后转到前端并刷新,然后尝试再次发送.

If you are using localhost and your php server side code is in a plugin file first login to admin dashboard and refresh the plugin page. Secondly, check if the plugin is activated. Then go to frontend and refresh and try sending again.

你试试:

add_action('init','ly_form_ajax_init');


函数ly_form_ajax_init(){
    wp_register_script('ly-form-ajax-script',plugins_url().'/ly-form/js/ly-script.js',array('jquery'));
    wp_enqueue_script('ly-form-ajax-script');

    wp_localize_script('ly-form-ajax-script','ly_form_ajax_object',array(
        'ajaxurl'=> admin_url('admin-ajax.php'),
        'redirecturl'=> home_url(),
        'loadingmessage'=> __('')
    ));
}
//动作是:contact_ajax
add_action('wp_ajax_contact_ajax','my_function');
add_action('wp_ajax_nopriv_contact_ajax','my_function');

函数my_function(){
    ob_clean();
    回声" http://sanvatvungcao.com";
    wp_die();
}

/**
 *页面中的短代码如下:[ly-form]
 * @参数类型$ atts
 * @参数类型$ content
 * @返回字符串
 */
函数ly_form_shortcode($ atts,$ content=""){
    回声html_form_code();
}
add_shortcode('ly-form','ly_form_shortcode');

//HTML表单将显示,
函数html_form_code(){
    $ html="";
    $ html.='';
    $ html.='';

    $ html.='
Họđệm* 
';
    $ html.='

    $ html.='

    $ html.='

    $ html.='

';
    $ html.='';

    $ html.='';
    $ html.='';
    $ html.='';


    返回$ html;
}

和这里js(ly-script.js):
(函数($){
    $(document).ready(function(){
//执行AJAX表单提交
        $('form.ly-form-ex').on('submit',function(e){
 e.preventDefault();
            $('#loading').html('loading ...');
            var dataString={action:'contact_ajax'};
            $ .ajax({
                输入:" POST",
                网址:ly_form_ajax_object.ajaxurl,
                数据:dataString,
                成功:功能(数据){
                    $('#loading').html(data);
                },
                错误:函数(errorThrown){
                    警报(错误抛出);
                }

            });
        });
    });//结束准备
})(jQuery);

Hope it is helpful for you, Best

尝试添加if语句:

 function my_function(){
$id = $_POST['variation_id'];

    if(isset($_POST['variation_id'])) { 


//your coded function


die();
}



}// end function
 

Try adding an if statement:

function my_function(){
$id = $_POST['variation_id'];

    if(isset($_POST['variation_id'])) { 


//your coded function


die();
}



}// end function
