我创建了一个插件，可以通过ajax提交表单。下面是php函数。

add_action(\'wp_ajax_nopriv_audience_intel\', \'audience_intel_ajax\');
add_action(\'wp_ajax_audience_intel\', \'audience_intel_ajax\');
function audience_intel_ajax() {
    $likeit = $_POST[\'likeit\'];
    $response = $_POST[\'response\'];
    $postid = $_POST[\'postid\'];

    add_option( \'testing_form_like\', $likeit );
    add_option(\'testing_form_response\', $response);

    global $wpdb;
    $tablename = $wpdb->prefix . "intel";

    $newdata = array(
        \'radio\' => $likeit,
        \'feedback\' => $response,
        \'postid\' => $postid
    );    

        $wpdb->insert (
        $tablename,
        $newdata
    );

    $result = "<p>Finished successfully!</p>";
    // json_encode($result);
    echo $result;
}

这是我的剧本。

jQuery(document).ready(function($) {
$(\'.audience_intel_container .close\').click(function(){
    $(\'.audience_intel_container\').fadeOut(\'fast\', function(){

    });
});

$(\'.audience_intel_container button\').click(function(){
    console.log(\'clicked\');
    var formdata = $(\'#audience_intel_form\').serialize();
    $.ajax({
        type : "post",
        dataType : "html",
        url : audience_intel_js.ajaxurl,
        data : \'action=audience_intel&\'+formdata,
        success: function(response) {
            alert(response);
            $(\'.audience_intel_container\').html(response);
        }
    })
})   
});

表单数据已正确添加到数据库，但我无法在请求完成后显示输出消息。我在ajax函数中尝试了return、echo和echo json\\u编码。

我很欣赏你的见解。

   jQuery(document).ready(function($) {
        $(\'.audience_intel_container .close\').click(function(){
        $(\'.audience_intel_container\').fadeOut(\'fast\', function(){

        });
});

$(\'.audience_intel_container button\').click(function(){
    console.log(\'clicked\');
    var formdata = $(\'#audience_intel_form\').serialize();
    $.ajax({
        type : "post",
        dataType : "html",
        url : audience_intel_js.ajaxurl,
        data : \'action=audience_intel&\'+formdata,
        success: function(response) {
            alert(response);
            $(\'.audience_intel_container\').html(response);
        }
    })
})   
});

add_action(\'wp_ajax_nopriv_audience_intel\', \'audience_intel_ajax\');
add_action(\'wp_ajax_audience_intel\', \'audience_intel_ajax\');
function audience_intel_ajax() {
$likeit = $_POST[\'likeit\'];
$response = $_POST[\'response\'];
$postid = $_POST[\'postid\'];

add_option( \'testing_form_like\', $likeit );
add_option(\'testing_form_response\', $response);

global $wpdb;
$tablename = $wpdb->prefix . "intel";

$newdata = array(
    \'radio\' => $likeit,
    \'feedback\' => $response,
    \'postid\' => $postid
);

$wpdb->insert (
    $tablename,
    $newdata
);

$result = "<p>Finished successfully!</p>";
// json_encode($result);
echo $result;
exit;
}
