Ajax 来自前端的调用不适用于 wordpress

Question

调用 Ajax 无法从 WordPress 的前端工作，我只想根据 id 从数据库中获取数据，这就是我到目前为止所尝试的方法。

//Frontend view

<a href="javascript:void(0)" onclick="getDetails(<?=$index;?>)" >
        <?php echo $value ?>
    </a>

//Functions.php

function my_enqueue() {
      wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/assets/js/ajax-script.js', array('jquery') );
      wp_localize_script( 'ajax-script', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
 }

 add_action( 'wp_enqueue_scripts', 'my_enqueue' );
 add_action('wp_ajax_nopriv_more_posts', 'get_more_posts');

function get_more_posts(){
    // How to get id here to query for the database
    echo "Hello World";
    exit(); 
}

// Ajax scripts File
function getDetails(id)
{
jQuery.ajax({
    url: more_posts.ajax_url,
    type: "GET",
    data: {
        action: 'more_posts'
    },
    dataType: "html",
    success: function(response){
        alert(response);
    }
});
}

我遇到了这个错误

reference error more_posts is not defined

//Frontend view

<a href="javascript:void(0)" onclick="getDetails(<?=$index;?>)" >
        <?php echo $value ?>
    </a>

//Functions.php

function my_enqueue() {
      wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/assets/js/ajax-script.js', array('jquery') );
      wp_localize_script( 'ajax-script', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
 }

 add_action( 'wp_enqueue_scripts', 'my_enqueue' );
 add_action('wp_ajax_nopriv_more_posts', 'get_more_posts');

function get_more_posts(){
    // How to get id here to query for the database
    echo "Hello World";
    echo $_GET['id'];
    exit(); 
}

// Ajax scripts File
function getDetails(id)
{
var id = id;
jQuery.ajax({
    url:  url: my_ajax_object.ajax_url,
    type: "GET",
    data: {
        action: 'get_more_posts',
        id: id,
    },
    dataType: "html",
    success: function(response){
        alert(response);
    }
});
}

这应该有效！您不需要带有“href”的绝对路径或 var，url: my_ajax_object.ajax_url 就足够了，因为您已经使用 wp_enqueue_script 添加了 admin-ajax.php。谢谢

你错了

  url: more_posts.ajax_url

因为你本地化的脚本名称是my_ajax_object

 wp_localize_script( 'ajax-script', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );

试试这个

 url: my_ajax_object.ajax_url
