Wordpress:通过ajax调用插件php文件

Question

我写了一个wordpress插件女巫在我的模板中添加了一些评论功能.通过ajax,所有的东西都应该传输到wordpress数据库.

问题是 - ajax处理程序需要一个php文件来捕获查询

if(isset($_POST['name'], $_POST['title'], $_POST['description'])) { 

 // do something with wordpress actions, e.g. get_current_user, $wpdb

}

在用户传输查询时,ajax处理程序调用php文件,如下所示:

$('#ajax_form').bind('submit', function() {
    var form = $('#ajax_form');
    var data = form.serialize();
    $.post('../wp-content/plugins/test/getvars.php', data, function(response) {
        alert(response);           
    });
    return false; 

该getvars.php不知道WordPress的环境,因为它是由用户直接调用提交,我想补充的WordPress的环境类,包括是不是好作风.

还有其他方法吗？感谢你的支持.

是的使用builtin wordpress ajax动作:

你的jquery看起来像这样:

$('#ajax_form').bind('submit', function() {
    var form = $('#ajax_form');
    var data = form.serialize();
    data.action = 'MyPlugin_GetVars'
    $.post('/wp-admin/admin-ajax.php', data, function(response) {
        alert(response);           
    });
return false; 

你的插件代码如下:

add_action("wp_ajax_MyPlugin_GetVars", "MyPlugin_GetVars");
add_action("wp_ajax_nopriv_MyPlugin_GetVars", "MyPlugin_GetVars");

function MyPlugin_GetVars(){
    global $wpdb;
    // use $wpdb to do your inserting

    //Do your ajax stuff here
    // You could do include('/wp-content/plugins/test/getvars.php') but you should
    // just avoid that and move the code into this function
}
