What is the way of add just label into a form and modify its value with the entity atribute value related to the form. PRE_SET_DATA event is properly executed but I don't know how to set its value. Picture code and result:
Cheers!
There is no way to just add a label (without textArea) dynamically, at least in Symfony 2.8 . I worked it around using an non-mapped disabled text without label.
You have to ADD again the same element name into PRE_SET_DATA function and 'thanks God Symfony' it keeps the order.
Cheers everyone!!

I have my Zend_Form, and sometimes, one of the fields should be hidden, and not seen by the user. Is there a way when I call the form in my controller, I could change one of the fields to be hidden?
Thanks

You can remove the element using:
$form->removeElement('my-element-name');
in the controller.
You could also create two forms, one overriding the other, in which the child calls $this->remove('my-element-name').
Or, you could make the form constructor accept a boolean $flag that determines whether to add the field to the form.
So, as you can see, lots of different ways to structure it.
To change that field to one of type "hidden" (i.e. <input type="hidden">) is a different thing, but I'm not sure that's what you mean/need/want.
The best solution I have for this is to add a specific class to the element when it needs to be hidden. It may not be the perfect solution, but let me explain.
First, its very difficult to switch from one element type to another in Zend Form. Your elements are actually classes. So the text is Zend_Form_Element_Text - so its not just as easy as changing the 'type' attribute.
If the element must remain on the form (so, not removing it like the answer above suggests), your only other option would be hiding it with CSS.
Try the following code when it needs to be hidden:
$element = $form->getElement('MyElement');
$newClass = trim($element->getAttrib('class') . ' hidden');
$element->setAttrib('class', $newClass);
Then, of course, create CSS for the .hidden class.
Hope this helps!
I need to set the value of a symfony2 form element.
I use a doctrine2 entity, a Symfony\Component\Form\AbstractType and the createForm() method inside my Controllers Action.
$saleDataForm = $this->createForm(new SaleType(), $sale);
Now, how do i get an element from that form, and how can i set it's value?
I want to do something like this, but it doesn't work:
$saleDataForm->get('image')->setValue('someimapge.jpg');
FYI: I need to do this to render the field correctly (using this approach, my image field is always empty and i need to set it to the content of imagePath to present a preview of an uploaded image)
For a more exact answer you should include the entities you use in this form so we can see the getters and setters. But based on your question this should work:
Inside the controller do this:
$saleDataForm->getData()->getImage()->setValue('someimage.jpg');
$form->setData($form->getData());
This is if the form is already created so:
$saleDataForm = $this->createForm(new SaleType(), $sale);
$saleDataForm->getData()->getImage()->setValue('someimage.jpg');
$form->setData($form->getData());
To get the data use this:
$saleDataForm->getData()->getImage()->getValue();
thanks MatsRietdijk, you helped me, but I had to change code to this
$form = $this->createForm(new SaleType(), $sale);
$form->getData()->setImage('someimage.jpg');
$form->setData($form->getData());
If you try fill file upload field - it's wrong idea. Ask yourself: what data should be there? If an user upload an image, then in this field will be a path to the image on his local system. But then after file is uploaded you change its name and location, so you don't need info about this path and you just don't keep it.
The appropriate way should be left empty upload field below (or above, or wherever you have it ;) ) image. Then after form is submitted and if the field is not empty you should change edited image.
I have divided form in to two sections: sec1 and sec2. Each section is part of a div named as sec1Div and sec2Div. Based upon some selection one of div is hidden. But the problem is that still fields in hidden section are submitted. Please suggest a way so that all of fields in a div are not submitted on submit.
There are several ways to do that. You can hook a function to the form submit's event, or you can remove the name attributes of the fields inside the hidden div. You can also disable the fields, by setting disabled="disabled".
If you are using jQuery, you can do those examples.
To disable all fields in the hidden div, you can do something like:
function hideDiv(el) {
$('input', el).each(function(){
$(this).attr('disabled', 'disabled');
});
$(el).hide();
}
And, the appropriate show div function:
function showDiv(el) {
$('input', el).each(function(){
$(this).removeAttr('disabled');
});
$(el).show();
}
Please remind that this is just a code example. But you can take the idea from that.
The reason this is happening is because the elements are still within the form element. Hiding a div using CSS won't change this - they're still present in the DOM.
It would likely be easiest to add a hidden input field to each div that can be used to identify server side which one you should be processing. You can then simply ignore the data from the hidden form.
If you really must stop the data from being posted, it's a little messy but you could move the hidden div's contents outside of the form element so that the fields won't be submitted. If you wanted to display the div again, you'd then need to move the fields back in. Depending on how complex your CSS is, this could cause problems in some browsers, so I'd advise using my first suggestion.
I'm creating my form using the Form helper, so the action of the form is specified automatically....
this form is used for editing a post..
so, the URL has the structure: mywebsite.com/posts/edit/id
and the form's action should be automatically generated as posts/edit/id
but the problem is, in some cases, I open the HTML code and I find that the form's action is only posts/edit without the id which causes the update to fail...
I spent a lot of time to figure out what situation brings this wrong action:
i'm generating fields dynamically (using javascript & ajax) depending on the post's category..
when the value of one of the dynamically generated fields is invalid, the generated action becomes posts/edit !!
I really need help, cuz I don't know why this is happening !!!
and I don't wanna waste more time digging into the core of cakephp...
so, if any of cakephp experts has an idea about this, plz help me !!
thank you in advance !
Use the url parameter, which allows you to explicitly define a url for the form:
echo $form->create('Post', array('url' => $html->url(array('action'=>'edit', $id))));
It sounds like $id probably isn't getting set, because it should be getting passed along if it is. You need to make sure it's set to edit the record in question. Make sure your javascript is including the hidden field with the record's id in it.
Normally done like this, with the form helper: echo $this->Form->input('id');
Also, if one of the fields is invalid, the form shouldn't actually be submitting properly, if you are using cake's validation, so this is to be expected.
