如何将php变量传递给wordpress AJAX处理程序 [英] How to pass php variable to wordpress AJAX handler

问题描述

努力将一些php变量传递到functions.php中的ajax处理程序函数中

Struggling to pass through some php variables into my ajax handler function in functions.php

下面提供的示例不起作用，可能与挂钩有关，但我找不到有关如何执行此操作的任何信息:

Example provided below doesn't work, probably has something to do with the hooks but I can't find any info on how to do this:

/*Unsubscribe*/
$test_variable = "derp";

function user_unsubscribe($test_variable){
  echo json_encode($test_variable);
  wp_die();
};

add_action('wp_ajax_user_unsubscribe', 'user_unsubscribe');
add_action('wp_ajax_nopriv_user_unsubscribe', 'user_unsubscribe');

推荐答案

您可以在ajax数据中传递该PHP变量.请检查以下文件，这些文件中我已从jQuery向Ajax函数发送了"test_variable"值.

You can pass that PHP variable in ajax data. Please check below files in which I had send the "test_variable" Value to Ajax Function from jQuery.

jQuery文件代码

Jquery File Code

jQuery(document).ready(function($) {    
    $('#btn').on('click',function(){
      $.ajax({ 
           data: {action: 'get_listing_names','test': global.test_variable},
           type: 'post',
           url: global.ajax,
           success: function(data) {
            console.log(data);
          }
      });
    });
});

Functions.php文件代码.

Functions.php file Code.

<?php
/**
 * Enqueue scripts and styles.
 *
 * @since 1.0.0
 */
function ja_global_enqueues() {

    wp_enqueue_script(
        'global',
        get_template_directory_uri() . '/js/global.js',
        array( 'jquery' ),
        '1.0.0',
        true
    );
    wp_localize_script(
        'global',
        'global',
        array(
            'ajax' => admin_url( 'admin-ajax.php' ),
            'test_variable' => 'Test Value',
        )
    );
}
add_action( 'wp_enqueue_scripts', 'ja_global_enqueues' );


add_action('wp_ajax_nopriv_get_listing_names', 'ajax_listings');
add_action('wp_ajax_get_listing_names', 'ajax_listings');


function ajax_listings() {

    $test_variable = $_POST['test_variable'];


    wp_send_json_success( $test_variable );        

}
