如何使用Symfony3和Ajax将tinyMCE textarea编辑器内容发送到内部控制器

Question

I have two tinyMCE editor with id's like #homepage, #thankyoupage, I want to send tinymce textarea content to inside symfony controller.

This is my front end part:

I am trying to send normal textarea value using jQuery ajax like below but I am getting undefined value.

$(document).ready(function () {
    var array_data = {};
    array_data['dedline'] = $('#homepage').val();
    array_data['homepage'] = $('#thankyoupage').val();
    array_data['thankyoupage'] = $('#deadlinetoanswer').val();
    $.ajax({
        type: 'POST',
        url: Routing.generate("invitation"),
        contentType: 'application/x-www-form-urlencoded',
        data: {
            data_array: array_data
        },
        success: function (result, status, xhr) {
            var res = JSON.parse(result);
            console.log(res);
        },
        error: function (xhr, status, error) {
            console.log('error1');
        }
    });
});

This is my form:

$builder->add('deadlinetoanswer', ChoiceType::class, array(
    'choices' => array(
        '2 days' => 2,
        '3 days' => 3,
        '5 days' => 5,
        '7 days' => 7,
        '10 days' => 10,
        '15 days' => 15,
        'Until' => 'until'
    )
));

$builder->add('prerecwelcomemsg', TextareaType::class, array(
    'required' => true,
    'attr' => array('class' => 'tinymce', 'id' => 'homepage', 'data-theme' => 'bbcode', 'style' => 'height: 380px', 'placeholder' => "Welcome...")
));

$builder->add('prerecthankyoumsg', TextareaType::class, array(
    'required' => true,
    'attr' => array('class' => 'tinymce', 'id' => 'thankyoupage', 'data-theme' => 'bbcode', 'style' => 'height: 380px', 'placeholder' => "Thank you...")
));

This is my controller:

/**
 * @Route("/prerecorded/invitation", name="invitation", options={"expose"=true})
 */
public
function invitationAction(Request $request) {
    $em = $this - > getDoctrine() - > getManager();
    $form = $this - > createForm(InvitationType::class);
    $form - > handleRequest($request);

    if ($request - > isXmlHttpRequest()) {
        $res_arr = $request - > request - > get('data_array');
        //   $this->container->get('logger')->addInfo('somesh'.$res_arr);           
        if ($res_arr) {
            $campaignid = 1;
            $campaign = $em - > getRepository('TraceBundle:Campaign') - > findOneBy(array('id' => $campaignid));
            $campaign - > setDeadlinetoanswer('');
            $campaign - > setPrerecwelcomemsg('hello');
            $campaign - > setPrerecthankyoumsg('how r u');
            $em - > persist($campaign);
            $em - > flush();
            return new Response(json_encode($campaignid));
        }
    }
    return $this - > render('TraceBundle:Campaign:invitation.html.twig', array(
        'form' => $form - > createView(),
    ));
}

and my config.yml

stfalcon_tinymce:
    include_jquery: true
    tinymce_jquery: true
    selector: ".tinymce"
  #  base_url: "http://yourdomain.com/" # this parameter may be included if you need to override the assets_base_urls for your template engine (to override a CDN base url)
    # Get current language from the parameters.ini
    language: %locale%
    # Custom buttons

            image: "http://stfalcon.com/favicon.ico"

    theme:

             toolbar2: "print preview media | forecolor backcolor emoticons | stfalcon | example"
             image_advtab: true
             templates:
                 - {title: 'Test template 1', content: 'Test 1'}
                 - {title: 'Test template 2', content: 'Test 2'}
        # BBCode tag compatible theme (see http://www.bbcode.org/reference.php)
        bbcode:
             plugins: ["bbcode, code, link, preview"]
             menubar: false               
             toolbar1: "styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist "

This is first time I am working tinyMCE editor, really I am not sure where I am doing wrong. Please help me anyone and let me know is there any extra information is needed.

Thanks in advance

Answer 1

1. Setting a custom id attribute in the form builder won't work.

There are two ways to fix that:

• Don't change the default id

In your script, use the default id attributes, generated by Symfony. For simple properties it's the name of the form and the name of the field separated by an underscore, so you can target your fields this way (selector 'id ends with'):

array_data['homepage'] = $('[id$="_prerecwelcomemsg"]');
array_data['thankyoupage'] = $('[id$="_prerecthankyoumsg"]').val();
array_data['deadlinetoanswer'] = $('[id$="_deadlinetoanswer"]').val();

(*) check the id attributes generated in the rendered html page to be sure.
(**) notice that you swapped the fields in your script, setting array_data['dedline'] to $('#homepage').val() .

• If you really need to change the id attributes:

You can do it in the template when you render the fields with:

{{ form_row(form.prerecwelcomemsg, { 'id': 'homepage' }) }}

2. You have to use TinyMCE's methods to get the edited content.

For this, either:

• Call tinyMCE.triggerSave(); before getting the fields value the way you do.
• Or get the content with tinyMCE.get('fieldFullId').getContent();
