使用 Ajax 将表单数据发布到 ZF2 控制器

Posting Form Data to ZF2 Controller With Ajax(使用 Ajax 将表单数据发布到 ZF2 控制器)

本文介绍了使用 Ajax 将表单数据发布到 ZF2 控制器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

编辑-
我已经在下面发布了答案.

问题是我不明白按下提交按钮时 ZF2 如何/在哪里发布表单数据.所以,当我做
if ($this->getRequest()->isPost()){
在下面的 ajax 调用之后,它告诉我没有发布任何数据.

当我执行上述 isPost() if 语句时,它在我点击提交按钮时完美运行,告诉我数据已发布,随后告诉我表单数据有效.

The question is that I don't understand how/where ZF2 posts form data when a submit button is pressed. So, when I do
if ($this->getRequest()->isPost()){
after the ajax call below, it tells me that no data has been posted.

When I do the above isPost() if statement it works perfectly when I hit the submit button, telling me the data has been posted and subsequently telling me that the form data is valid.

这里是ajax调用-

            <script>
                $.ajax({
                    url: urlform,
                    type: 'POST',
                    dataType: 'json',
                    contentType: "application/json; charset=utf-8",
                    async: true,
                    data: ($("#newThoughtForm").serialize() + '&submit=go'),
                    success: function () {
                        console.log('SUBMIT WORKS');
                        setTimeout(function () { <?php echo $this->invokeIndexAction()->test(); ?> ;
                        }, 1000);
                    },
//This keeps getting executed because there is no response, as the controller action is not run on a Post()
                    error: function () {
                        console.log('There is error while submit');
                        setTimeout(function () { <?php echo $this->invokeIndexAction()->test(); ?> ;
                        }, 1000);
                    }
//I assume the data won't get pushed to the server if there is no response,
//but I can't figure out how to give a response in ZF2 since the controller is not
//run when the Post() is made. 
                });

这是表格-

            use ZendFormForm;

            class newAlbumForm extends Form
            {
                public function __construct()
                {
                    parent::__construct('newAlbumForm');
                    $this->setAttribute('method', 'post');

                    $this->add(array(
                        'type' => 'AlbumModuleForm
ewAlbumFieldset',
                        'options' => array(
                            'use_as_base_fieldset' => true
                        )
                    ));

                    $this->add(array(
                            'name' => 'submit',
                                'attributes' => array(
                                    'type' => 'submit',
                                    'value' => 'go'
                        ),
                    ));
                }
            }



ajax调用请求-



The request for the ajax call-

这是控制器上的 indexAction() 以确保完整性-



Here is the indexAction() on the controller for completeness-

            public function indexAction()
            {
                echo 'console.log("Index Action is Called");';

                $form = new AlbumModuleForm
ewAlbumForm();
                if ($this->getRequest()->isPost()){
                    echo 'console.log("Data posted");';

                    $form->setData($this->getRequest()->getPost());
                    if ($form->isValid()){
                        echo 'console.log("Form Valid");';

                        //todo
                        $this->forward()->dispatch('newAlbum', array('action' => 'submitAlbum'));
                        return new ViewModel(
                            array(
                                    'form' => $form
                            )
                        );
                    } else {
                        echo 'console.log("Form Invalid");';

                        return new ViewModel(
                            array(
                                    'form' => $form
                            )
                        );
                    }
                } else {
                    echo 'console.log("No data posted")';
                    return new ViewModel(
                            array(
                                    'form' => $form
                            )
                        );
                }
            }

正如我在开头所说的,isPost() 类在按钮提交表单时会返回 true 值,但是当通过 Ajax 提交表单时它会返回 false 值.

As I stated at the beginning, the isPost() class will return a value of true when the button submits the form, but it will return a value of false when the form is submitted through Ajax.

推荐答案

通常当你从 ajax 发送数据时,你不需要再次渲染你的模板,这就是 ViewModel 所做的.

Usually when you send data from ajax, you don't need to render your template again, and that's what ViewModel do.

尝试将 json 策略添加到您的 module.config.php

Try to add json strategy to your module.config.php

'view_manager' => array(
    //other configuration
    'strategies' => array(
        'ViewJsonStrategy',
    ),
),

那么您的操作应该如下所示:

Then your action should look like this:

public function ajaxAction()
{
    $request = $this->getRequest();

    if ($request->isXmlHttpRequest()){ // If it's ajax call
        $data = $request->getPost('data'));
        ...
    }


    return new JsonModel($formData);
}
