我有一个表单,我正在使用我的插件中的标准WP Ajax技术将一些数据传递给我的AJAX动作函数:
基本形式:
<form role="form" id="signup_widget_form" method="post" action="#">
<input name="action" type="hidden" value="do_ajax_signup" />
<div class="input-group">
<input type="email" class="form-control" id="signup_email" placeholder="Email">
<label for="signup_email" class="sr-only">Email</label>
<span class="input-group-btn">
<button type="submit" class="btn btn-default">Sign Up</button>
</span>
</div>
</form>
<div class="alert" id="signup_form_response"></div>
在我的插件的主要php文件中:
//Instantiate the AJAX handler and load our jQuery
add_action( 'wp_enqueue_scripts', 'signup_enqueue_scripts' );
function signup_enqueue_scripts(){
wp_enqueue_script( 'signup-ajax-handle', plugin_dir_url( __FILE__ ) . 'ajax.js', array( 'jquery' ) );
wp_localize_script( 'signup-ajax-handle', 'signup_ajax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}
// The AJAX add actions
add_action( 'wp_ajax_do_ajax_signup', 'do_ajax_signup' );
add_action( 'wp_ajax_nopriv_do_ajax_signup', 'do_ajax_signup' );
// This will perform the server-side AJAX stuff and return a response
function do_ajax_signup(){
$email = $_POST['signup_email'];
echo "Your email is " . $email; //this is passed back to the javascript function
print_r($_POST); print_r($_GET);
die();
}
执行AJAX的jQuery:
jQuery(document).ready(function($){
$('#signup_widget_form').submit(function(){
var form = $(this),
formData = form.serialize(),
formMethod = form.attr('method'),
responseMsg = $('#signup_form_response');
$.ajax({
url: signup_ajax.ajaxurl,
data: formData,
method: formMethod,
success: function(data) {
responseMsg.html(data);
}
});
return false; //prevent form from submitting
});
});
这一切正常,Ajax callaback通过将do_ajax_signup()
的响应输出到#signup_form_response
div来工作。麻烦的是,from数据似乎没有传递给do_ajax_signup()
。响应仅包含:
您的电子邮件是数组([action] =&gt; do_ajax_signup)数组()
为什么$_POST
变量不包含我的序列化表单数据?
答案 0 :(得分:2)
您缺少signup_email
个<input>
元素的名称属性。
<input type="email" ... name="signup_email">
^^^^^^^^^^^^^^^^^^^^^
