这样做真的不是最好的做法。事实上，您不需要创建ajax。php文件，除非您打算将其包含在函数中。php文件。您需要阅读WordPress中的AJAX。您只需在“wp\\u ajax\\u name\\u of\\u action”上添加一个操作，并在javascript ajax函数中指定该操作即可。

WordPress编解码器的简单示例：

<?php
add_action(\'admin_head\', \'my_action_javascript\');

function my_action_javascript() {
?>
<script type="text/javascript" >
jQuery(document).ready(function($) {

var data = {
    action: \'my_action\',
    whatever: 1234
};

// since 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php
jQuery.post(ajaxurl, data, function(response) {
    alert(\'Got this from the server: \' + response);
});
});
</script>
<?php
}
add_action(\'wp_ajax_my_action\', \'my_action_callback\');

function my_action_callback() {
global $wpdb; // this is how you get access to the database

$whatever = intval( $_POST[\'whatever\'] );

$whatever += 10;

    echo $whatever;

die(); // this is required to return a proper result
}
