I am trying to create a dynamic value for a form attribute that is auto-populated based on a previous setting stored in the database. It works fine in HTML with a little Laravel and looks like:
<input type="text" class="class" id="firstName" placeholder="First Name" value="{{ $user->firstName }}">
But I want to fully generate the entire form in Laravel. I'm unsure how to pass the value into the array. I can't seem to get the form to pull the information. Here is how it is currently looking:
{{ Form::text('first_name', '', [
'class' => 'class',
'id' => 'firstName',
'placeholder' => 'First Name',
'value' => $user->firstName
])}}
Try this:
{{ Form::text('first_name', $user->firstName, [
'class' => 'class',
'id' => 'firstName',
'placeholder' => 'First Name'
])}}
For more information regarding this topic, visit this
See, if that works.
To specify a default value in laravel's form generator, the second value you pass in is made for you:
{{ Form::text('first_name', $user->firstName,
[
'class' => 'class',
'id' => 'firstName',
'placeholder' => 'First Name',
]
) }}
Please note that from laravel 5, being published next week, the form helpers are removed (and for the actual state the installable replacement packages don't work very well/without bugs). So if you are planning on upgrading to laravel 5 better don't use this, instead go with html form elements.

How can i add a new personalized attribute with zend From, exemple <input type='text' **ref='name**' name='id_commande' id='commande'/>
Use setAttrib on element for single, or setAttribs for multiple attributes you want to add
This should make a job:
$id_commande = new Zend_Form_Element_Text('id_commande');
$id_commande->setAttribs([
'ref' => 'name',
'class' => 'your_class',
'style' => 'width: 150px'
]);
I'm trying to figure out why ZF3 encodes my element's class string, but can't find anything about that behaviour on the internet.
$this->add([
'type' => 'Button',
'name' => 'submitLogin',
'options' => [
'label' => '<i class="zmdi zmdi-check"></i>',
'label_options' => [
'disable_html_escape' => true,
]
],
'attributes' => [
'type' => 'submit',
'class' => 'btn btn--icon login__block__btn',
],
]);
becomes
<button type="submit" name="submitLogin" class="btn btn--icon login__block__btn" value=""><i class="zmdi zmdi-check"></i></button>
I think this is an abstract concept. Generally we take some steps when we work with data. We filter input values and escape outputs. This is a security philosophy.
Zend Framework did the same thing while something is about security. This means this behavior is by default. ZF escapes attributes' values when it is being displayed onto the browser. ZF only allows non-escaping through explicit options like you did for the label's content above.
You will get some concept via this issue on github where Matthew said:
Secure by default is the mantra
Using Symfony 3.2 on Ubuntu 16.04
I created a FormType.php with several fields. One of them is a phone number, so I added a constraint where only numbers could be accepted. Here is the code for the phone form
->add('authorPhone', NumberType::class, array('label' => 'Numéro de téléphone',
'required' => true,
'attr' => array(
'class' => 'validate',
'id' => 'icon_telephone'
),
'constraints' => array(new Regex("#^0[1-9]([-. ]?[0-9]{2}){4}$#"))
))
After that, in my controller I added an error to tell that numbers only need to be filled in
public function indexAction()
{
$form = $this->createForm(FormType::class);
$form->get('authorPhone')->addError(new FormError('error message'));
return $this->render('app/main/index.html.twig', array(
'form' => $form->createView()
));
}
But when I look at my page the error message is actually showing without having filled the field. And of course I don't want that.
(you can see under "Numéro de téléphone", which means phone number)
I only want numbers in my phone number field, and if there are letters, an error should be displayed or something saying it's not right.
Standard how to to this stuff in Symfony is to define an entity with contraints and error messages and then create entity bound form which will handle validation based on entity's contraints automatically.
But if you need, for some reason, independent form, it can be done to. The addError() method is for adding error "state" the the form field (e.g. for own validation) and you're adding the error by default right after the form is created. That's the reason why the error shows constantly.
UPDATED:
The right way to assign an error message to a form field is by the invalid_message property (which is showed when the entered value doesn't correspond with the field type). But when there's a constraint used for validation, then the err message has to be set according to the constraint validator - so, in your case, by associative array with pattern and message keys.
Next thing need to be corrected is TextType instead of NumberType, because when the NumberType is used, then it won't allow to enter dashes and also automatically trims leading zeros in numbers - so bad for phone numbers :-)
->add('authorPhone', TextType::class, array(
'label' => 'Numéro de téléphone',
'required' => true,
'attr' => array(
'class' => 'validate',
'id' => 'icon_telephone'
),
'constraints' => array(new Regex(
array(
'pattern' => '#^0[1-9]([-. ]?[0-9]{2}){4}$#',
'message' => 'Phone error message'
)
)),
))
And last thing to review - in the controller (after form declaration) has to be form submission handling routine:
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
....
You can learn more in Symfony's form submission handling: http://symfony.com/doc/current/forms.html#handling-form-submissions
Form rendering is fairly simple. Twig syntax to render whole form:
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
or, if you want to selectively render fields one by one:
{{ form_start(form) }}
{{ form_row(form.authorPhone) }}
{{ form_row(form.submit) }}
{{ form_end(form) }}
It'll renders complete field including labels and errors
I am trying to get used to work with Laravel's blade.
I would like to create a text input called company.
The input field needs to have an id and a class.
I also want to show a placeholder if there is no data in the database, or the data stored if already exists.
Finally, I would like to keep the introduced input in case of errors.
I would like to use something similar at this:
{{ Form::text(
'company',
isset($user->company)?$user->company:array('placeholder'=>'Your company'),
array('class' => 'field required', 'id' => 'company'),
Input::old('company')
) }}
Any help would be appreciated. Thanks!
The easy way, using form model binding:
{{ Form::model($user, [ ...options...]) }}
{{ Form::text(
'company', // refers to $user->company
null, // auto populated with old input in case of error OR $user->company
array('class' => 'field required', 'id' => 'company',
'placeholder' => 'Your company') // placeholder is html attribute, don't use model data here
) }}
And if you don't want form model binding, this is all you need:
{{ Form::text(
'company',
$user->company, // auto populated with old input in case of error
array('class' => 'field required', 'id' => 'company',
'placeholder' => 'Your company')
) }}
Laravel will handle re-populating inputs for you, so long as the key in the POST data is the same as your input’s name attribute.
With Form::text(), the first parameter is the field name, the second parameter is the default value you want, and the third parameter is an array of HTML attributes you want set. So, you would have:
{{ Form::text('company', null, array(
'class' => '',
'id' => '',
'placeholder' => '',
)) }}
Obviously replaced the class, id, and placeholder values with your desired values.
Found it!
It works fine for me if I do this:
{{ Form::text(
'company',
Input::old( 'company', $user -> company ) ,
array( 'class' => 'field required', 'id' => 'company', 'placeholder' => 'Your company' )
) }}
i need help with my dynamically extensible zend form.
I have form with subform, which contains two elements:
<form>
<fieldset class="itemGroup">
<label>
Question
<input type="text" name="items[questions][]" value="">
</label>
<label>
Answer
<input type="text" name="items[answers][]" value="">
</label>
</fieldset>
</form>
I obtained it with following procedure:
$itemsSubform = new Zend_Form_SubForm();
$form->addSubForm($itemsSubform, 'items');
$itemsSubform->setElementsBelongTo('items');
$itemQuestion = new Zend_Form_Element_Text('questions', array(
'label' => 'Question',
'isArray' => true,
'filters' => array(
'stringTrim',
),
'validators' => array(
array('stringLength', array('max' => 255)),
),
));
$itemAnswer = new Zend_Form_Element_Text('answers', array(
'label' => 'Answer',
'isArray' => true,
'filters' => array(
'stringTrim',
),
'validators' => array(
array('stringLength', array('max' => 255)),
),
));
$itemsSubform->addDisplayGroup(array($itemQuestion, $itemAnswer), 'itemGroup');
If is needed, i just copy all fieldset for extend form by javascript.
All is working correct, until i submit form. During validation is no element validated, and during rendering form, populated by such data, i get error message from class Zend_View_Abstract that escaping value is array instead of string (this method is called during rendering element for escape its value).
For compltion, if i call $form->getValues(); after validation, (by javascript another fieldset is added) i get this:
Array
(
[items] => Array
(
[questions] => Array
(
[0] => lorem
[1] => dolor
)
[answers] => Array
(
[0] => ipsum
[1] => sit
)
)
)
Could someone advise me how to behave to form? The ideal solution would be when form themselves validate each value separately and find how many times should he render fieldset (displayGroup).
First your elements fail to validate because you set isArray => TRUE and the validator you chose evaluates strings.
Next you issue with populating the form I believe is likely due to the fact that you need to supply the data to populate in the same multidimensional array as the form produces (the arrays should map one to one).
The link below is to an example of how to build a form dynamically, you should be able to use it as a template to produce one to fill your needs.
