post参数没有被传递zend框架2

Question

我通过ajax调用将post参数传递给控制器​​动作时遇到了一些问题.我不确定它为什么要这样做,因为其他ajax调用按预期执行.我得到的回应如下:

Notice: Undefined index: user_bio in C:\xampp\htdocs\module\Members\src\Members\Controller\ProfileController.php on line 149

控制器代码是:

public function changebioAction()
{
    $layout = $this->layout();
    $layout->setTerminal(true);

    $view_model = new ViewModel();
    $view_model->setTerminal(true);

    if ($this->request->isPost()) {
        try {
            $params = $this->params()->fromPost();

            $this->getProfileService()->editProfile(array('bio' => ltrim($params['user_bio'])));
        } catch (ProfileException $e) {
            $this->flashMessenger()->addErrorMessage($e->getMessage());

            return $this->redirect()->toRoute('members/profile', array('action' => 'change-failure'));
        }
    }

    return $view_model;
}

javascript和html:

// handle quick edit of bio
function quickEditBio(element, button) {
    var edited_data = $(element).html();

    var data = $(element).blur(function() {
        edited_data = $(element).map(function() {
            return this.innnerHTML;
        }).get();
    });

    $(button).on('click', function() {
        $.ajax({
            method : "POST",
            url : "/members/profile/change-bio",
            data : {
                user_bio : edited_data[0]
            }
        }).done(function(msg) {
            // bio saved
            // go back to profile page
            //location.href = '/members/profile';
            alert(msg);
        }).fail(function() {
            alert("Error changing bio, please try again.");
        });
    });
}

<button onclick="expand('bio')" class="w3-btn-block w3-theme-d2 w3-left-align">
                <i class="fa fa-book fa-fw w3-margin-right"></i> Bio
            </button>

            <div id="bio" class="w3-accordion-content w3-container">
                <div class="w3-display-container">
                    <p id="bio-user" contenteditable="true">
                        <?php echo $this->layout()->bio; ?>
                    </p>

                    <div class="w3-display-right">
                        <button class="w3-btn-block w3-theme-d2" id="save-bio">Save</button>
                    </div>

                    <script type="text/javascript">
                        quickEditBio('#bio-user[contenteditable=true]', $('#save-bio'));
                    </script>
                </div>
            </div>

如前所述,我得到的错误是索引user_bio未定义:

Notice: Undefined index: user_bio in C:\xampp\htdocs\module\Members\src\Members\Controller\ProfileController.php on line 149

真正令人困惑的部分是其他部分使用相同的代码并且工作得很好.

任何帮助,将不胜感激.

谢谢!

Answer 1

问题在于你的JavaScript.

每次在元素上"模糊"时,它都会将edited_data变量设置为空数组.

edited_data[0] 然后变得未定义,并将注意发布到您的PHP.

这意味着$params['user_bio']将是未定义的索引,因为user_bio未作为参数被接收.

解决此问题:
删除$(element).map并替换它$(element).html();
也改为edited_data[0]编辑_data,因为这将不再是一个数组.
