I've got a problem with the name of displayed field's value. In my FormType i have something like below:
$builder->add(
'level',
'entity',
array(
'class' => 'AppBundle:Level',
'label' => false,
'property' => 'name',
'mapped' => false,
'attr' => array(
'class' => 'none'
)
)
);
And insteed of property name, I would like to display my own result of toString() method. How can I do this?
How to set a preferred choice in a form for radio button ?
What I need is to have a specific radio checked (the last of my 4 radio button) when I load the web page...
But I read that "preferred choice" is used just for a choice list not for radio or checkbox...
http://symfony.com/doc/current/reference/forms/types/choice.html#preferred-choices
I tried that:
->add('Offre', 'entity', array(
'class' => 'AVCMediasBundle:Offre',
'query_builder' => function (EntityRepository $repository) use ($parametre_langue) {
return $repository->createQueryBuilder('q')
->where('q.id = 4')
->orderBy('q.prix', 'DESC');
},
'property' => 'titre' . $parametre_langue,
'expanded' => true,
'multiple' => false,
'label' => false,
'preferred_choices' => array('1'),
'attr' => array(
'class' => 'langue_selector'
)
));
Thanks
My solution was to passed my choice directly in the entity when I load my form
$preferedOffer = $em->getRepository('AVCMediasBundle:Offre')->findOneById('4');
$DetailTransaction->setOffre($preferedOffer);
I am brand new to Zend and I've been given a project to make adjustments on. I'd like to add html to the labels for my form elements but I can't seem to get it right.
Here's what I have:
$this->addElement('text', 'school_name', array(
'filters' => array('StringTrim'),
'validators' => array(
array('StringLength', false, array(0, 150)),
),
'required' => true,
'label' => 'Name* :<img src="picture.png">,
'size' => '90',
));
As is, of course, the <img src="picture.png"> text gets escaped and the whole string is displayed.
I've read that I need to use 'escape' => false in some capacity but I can't figure out where/how to use it in my specific case.
Any help would be great. Thanks!
After calling addElement fetch the label's decorator and change the escape setting:
$form->getElement('school_name')->getDecorator('label')->setOption('escape', false);
If you use this type of label a lot, you should consider writing a custom decorator.
You can also use the disable_html_escape in 'label_options' when adding an element to the form:
$this->add(array(
....
'options' => array(
'label' => '<span class="required">Name</span>,
'label_options' => array(
'disable_html_escape' => true,
)
),
...
));

I'm working on a language choice form:
$currentLocale = "en_US"; // This is indeed sent to the formType
$langs = array(
'fr_FR' => 'fr',
'en_US' => 'en'
);
$builder->add('language', 'language', array(
'choices' => $langs,
'expanded' => true,
'multiple' => false,
'required' => false,
'label' => false,
));
The HTML code looks like this (simplified):
<div id="languageForm_language">
<input type="radio" value="fr_FR">
<input type="radio" value="en_US">
</div>
How could I get the second item pre-selected, according to the $currentLocale value ?
In your $langs array you can specify key value pairs like this:
array(
0 => 'value1',
1 => 'value2'
)
Now, e.g. you want to preselect value2, you can set the data attribute to the key from value2:
$builder->add('language', 'choice', array(
'choices' => $langs,
'expanded' => true,
'multiple' => false,
'required' => false,
'label' => false,
'data' => 1
));
According to this, you can set your data attribute to your $currentLocale variable to preselect it. Your code should look like this:
$currentLocale = "en_US"; // This is indeed sent to the formType
$langs = array(
'fr_FR' => 'fr',
'en_US' => 'en'
);
$builder->add('language', 'choice', array(
'choices' => $langs,
'expanded' => true,
'multiple' => false,
'required' => false,
'label' => false,
'data' => $currentLocale
));
Note: the second parameter from the add() method should be choice not language.
If the form is used with a model object, just set the language on the object itself before passing it to the form:
$object->setLanguage($currentLocale);
$form = $this->createForm('some_form_type', $object);
Otherwise, set the data option to the default language key:
$builder->add('language', 'language', array(
'choices' => $langs,
'data' => $currentLocale,
// ...
));
I've read numerous workarounds for Zend Framework's lack of default checkbox validation.
I have recently started using ZF2 and the documentation is a bit lacking out there.
Can someone please demonstrate how I can validate a checkbox to ensure it was ticked, using the Zend Form and Validation mechanism? I'm using the array configuration for my Forms (using the default set-up found in the example app on the ZF website).
Try this
Form element :
$this->add(array(
'type' => 'Zend\Form\Element\Checkbox',
'name' => 'agreeterms',
'options' => array(
'label' => 'I agree to all terms and conditions',
'use_hidden_element' => true,
'checked_value' => 1,
'unchecked_value' => 'no'
),
));
In filters, add digit validation
use Zend\Validator\Digits; // at top
$inputFilter->add($factory->createInput(array(
'name' => 'agreeterms',
'validators' => array(
array(
'name' => 'Digits',
'break_chain_on_failure' => true,
'options' => array(
'messages' => array(
Digits::NOT_DIGITS => 'You must agree to the terms of use.',
),
),
),
),
)));
You could also just drop the hidden form field (which I find a bit weird from a purist HTML point of view) from the options instead of setting its value to 'no' like this:
$this->add(array(
'type' => 'Zend\Form\Element\Checkbox',
'name' => 'agreeterms',
'options' => array(
'label' => 'I agree to all terms and conditions',
'use_hidden_element' => false
),
));
I had the same problem and did something similar to Optimus Crew's suggestion but used the Identical Validator.
If you don't set the checked_value option of the checkbox and leave it as the default it should pass in a '1' when the data is POSTed. You can set it if you require, but make sure you're checking for the same value in the token option of the validator.
$this->filter->add(array(
'name' => 'agreeterms',
'validators' => array(
array(
'name' => 'Identical',
'options' => array(
'token' => '1',
'messages' => array(
Identical::NOT_SAME => 'You must agree to the terms of use.',
),
),
),
),
));
This won't work if you use the option 'use_hidden_element' => false for the checkbox for the form. If you do this, you'll end up displaying the default NotEmpty message Value is required and can't be empty
This isn't directly related to the question, but here's some zf2 checkbox tips if you're looking to store a user's response in the database...
DO use '1' and '0' strings, don't bother trying to get anything else to work. Plus, you can use those values directly as SQL values for a bit/boolean column.
DO use hidden elements. If you don't, no value will get posted with the form and no one wants that.
DO NOT try to filter the value to a boolean. For some reason, when the boolean value comes out to be false, the form doesn't validate despite having 'required' => false;
Example element creation in form:
$this->add([
'name' => 'cellPhoneHasWhatsApp',
'type' => 'Checkbox',
'options' => [
'label' => 'Cell phone has WhatsApp?',
'checked_value' => '1',
'unchecked_value' => '0',
'use_hidden_element' => true,
],
]);
Example input filter spec:
[
'cellPhoneHasWhatsApp' => [
'required' => false,
],
]
And here's an example if you want to hide some other form fields using bootstrap:
$this->add([
'name' => 'automaticTitle',
'type' => 'Checkbox',
'options' => [
'label' => 'Automatically generate title',
'checked_value' => '1',
'unchecked_value' => '0',
'use_hidden_element' => true,
],
'attributes' => [
'data-toggle' => 'collapse',
'data-target' => '#titleGroup',
'aria-expanded' => 'false',
'aria-controls' => 'titleGroup'
],
]);
I'm a ZF2 fan, but at the end of the day, you just have to find out what works with it and what doesn't (especially with Forms). Hope this helps somebody!
Very old question, but figured it might still be used/referenced by people, like me, still using Zend Framework 2. (Using ZF 2.5.3 in my case)
Jeff's answer above helped me out getting the right config here for what I'm using. In my use case I require the Checkbox, though leaving it empty will count as a 'false' value, which is allowed. His answer helped me allow the false values, especially his:
DO NOT try to filter the value to a boolean. For some reason, when the boolean value comes out to be false
The use case is to enable/disable certain entities, such as Countries or Languages so they won't show up in a getEnabled[...]() Repository function.
Form element
$this->add([
'name' => 'enabled',
'required' => true,
'type' => Checkbox::class,
'options' => [
'label' => _('Enabled'),
'label_attributes' => [
'class' => '',
],
'use_hidden_element' => true,
'checked_value' => 1,
'unchecked_value' => 0,
],
'attributes' => [
'id' => '',
'class' => '',
],
]);
Input filter
$this->add([
'name' => 'enabled',
'required' => true,
'validators' => [
[
'name' => InArray::class,
'options' => [
'haystack' => [true, false],
],
],
],
])
