为什么我的 ajax 请求得到响应 0? [英] Why is my ajax request getting response 0?

问题描述

我已经在我的 wp 主题中设置了基本的 wordpress ajax 示例.触发器由 Modernizr.js 检查页面上的媒体查询生成.

jQuery(document).ready(function($) {if(Modernizr.mq('only all and (max-width:6300px)')) {变量数据 = {动作:'my_action'，无论如何:ajax_object.we_value//我们以不同的方式传递 php 值！};//我们也可以将 url 值与 ajaxurl 分开传递，用于前端 AJAX 实现jQuery.post(ajax_object.ajax_url, 数据, 函数(数据) {$("#trending-Container").html(data).fadeIn(1000);});}});//结束函数

我已经对我的脚本进行了本地化和排队.

wp_enqueue_script('mainJS', get_template_directory_uri() .'/js/mainJS.js', array("jquery") );wp_localize_script('mainJS', 'ajax_object',数组('ajax_url' => admin_url('admin-ajax.php')，'we_value' => 1234))；

最后处理请求的函数是:

add_action('wp_ajax_my_action', 'my_action_callback');add_action('wp_ajax_nopriv_my_action', 'my_action_callback');函数 my_action_callback() {全球 $wpdb;$whatever = intval( $_POST['whatever'] );$无论如何 += 10;回声 $whatever;死();}

这不断给我 0(没有属性)的响应，我不知道为什么.P.S 这都是本地的.

解决方案

这里的一切都必须匹配:

PHP

<前>add_action('wp_ajax_my_action', 'my_action');add_action('wp_ajax_nopriv_my_action', 'my_action');函数 my_action() {}

JS

<前>变量数据 = {动作:'my_action',无论如何:ajax_object.we_value};

此外，您还缺少安全检查和更好的响应处理.
检查以下示例:[ 1 ] 和 [2].

I've setup the basic wordpress ajax example in my wp theme. The trigger is made by modernizr.js checking the media queries on the page.

jQuery(document).ready(function($) {
    if(Modernizr.mq('only all and (max-width:6300px)')) {
        var data = {
        action: 'my_action',
        whatever: ajax_object.we_value      // We pass php values differently!
    };
    // We can also pass the url value separately from ajaxurl for front end AJAX implementations
        jQuery.post(ajax_object.ajax_url, data, function(data) {
            $("#trending-Container").html(data).fadeIn(1000);
        });
    }

});//end function 

I have localized and enqueue'd my scripts.

wp_enqueue_script('mainJS', get_template_directory_uri() . '/js/mainJS.js', array("jquery") );
wp_localize_script( 'mainJS', 'ajax_object', 
                    array( 'ajax_url' => admin_url( 'admin-ajax.php' ), 'we_value' => 1234 ) );

and finally the function that handles the request is:

add_action('wp_ajax_my_action', 'my_action_callback');
add_action('wp_ajax_nopriv_my_action', 'my_action_callback');
function my_action_callback() {
        global $wpdb;
            $whatever = intval( $_POST['whatever'] );
            $whatever += 10;
                echo $whatever;
            die();

        }

This constantly gives me a response of 0 (no properties) and I do not know why. P.S This is all local.

解决方案

Everything has to match here:

PHP

add_action('wp_ajax_my_action',        'my_action');
add_action('wp_ajax_nopriv_my_action', 'my_action');

function my_action() {}

JS

var data = {
    action: 'my_action',
    whatever: ajax_object.we_value 
};

Also, you're missing security checks and a better handling of the response.
Check this examples: [ 1 ] and [ 2 ].
