function get_data() {
$abc = '1';
$result = $wpdb->get_results("SELECT * FROM ".$wpdb->options ." WHERE option_name LIKE '_transient_%'");
echo $result; //returning this value but still shows 0

我的 ajax 调用是在 javascript 中
$('body').on("click", ".re-reset-btn", function(e){
var panel = $('#re-compare-bar');
$.ajax({
type : "GET",
dataType : "json",
url : "/wp-admin/admin-ajax.php",
data : {action: "get_data"},
success: function(response) {
alert("Your vote could not be added");
alert(response);
$("#re-compare-bar-tabs div").remove();
$('.re-compare-icon-toggle .re-compare-notice').text(0);
function my_enqueue() {
wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/js/my-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_enqueue_scripts',function(){
wp_enqueue_script('wp-util');
wp_enqueue_script('my-script', 'my-script.js', ['wp-util']);
wp-util 脚本包含可用于发出 ajax 请求的wp.ajax对象：
wp.ajax.post( action, data ).done( okCallback ).fail( errCallback )
你的例子：
wp.ajax.post( "get_data", {} )
.done(function(response) {
alert("Your vote could not be added");
alert(response);
add_action( 'wp_ajax_nopriv_get_data', 'my_ajax_handler' );
add_action( 'wp_ajax_get_data', 'my_ajax_handler' );
function my_ajax_handler() {
wp_send_json_success( 'It works' );
dataType : "json",
url : "<?php echo admin_url('admin-ajax.php'); ?>",
data : {action: "get_data"},
success: function(response) {
alert("Your vote could not be added");
alert(response);
$("#re-compare-bar-tabs div").remove();
$('.re-compare-icon-toggle .re-compare-notice').text(0);
</script>
echo 'Error';
} else {
echo "Customer '".$name. "' successfully added, row ID is ".$wpdb->insert_id;
die();
add_action('wp_ajax_addCustomer', 'addCustomer');
add_action('wp_ajax_nopriv_addCustomer', 'addCustomer');
type: "post",
dataType: "json",
url: "/wp-admin/admin-ajax.php", //this is wordpress ajax file which is already avaiable in wordpress
data: {
action:'get_data' //this value is first parameter of add_action,
id: 4
success: function(msg){
console.log(msg);
global $wpdb;
$abc = '1';
$result = $wpdb->get_results("SELECT * FROM ".$wpdb->options ." WHERE option_name LIKE '_transient_%'");
echo $result; //returning this value but still shows 0
wp_die();
wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/js/my-ajax- script.js', array('jquery') );
wp_localize_script( 'ajax-script', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
type:"POST",
url:my_ajax_object.ajax_url,
data: {action:'my_special_ajax_call_enroll_cours'},
success:function(res){
console.log(res);
});</script><?php
add_action('wp_ajax_my_special_ajax_call_enroll_cours', 'enroll_cours');
add_action('wp_ajax_nopriv_my_special_ajax_call_enroll_cours', 'enroll_cours');
function enroll_cours()
echo "Here you van write Query or anything";
exit;
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("demo").innerHTML = this.responseText;
document.getElementById("demo2").innerHTML = urlToajax+ "?action=testfirst";
xmlhttp.open("GET", urlToajax+ "?action=testfirst", true);
xmlhttp.send(0);
这里在functions.php中add_actions：
add_action( 'wp_ajax_testfirst', __NAMESPACE__ .'\FunctionTF' );
add_action( 'wp_ajax_nopriv_testfirst', __NAMESPACE__ .'\FunctionTF');
在上面添加这个函数，现在这个函数：
function FunctionTF(){
exit( "Hola hola" );
<div id="demo"></div>
<div id="demo2"></div>
<button id="spesial_button" onclick="P_lifg()">I am spesial</button>
