I've created a form using ZF2 when my whole system (page & server) is in french and has a ISO-8859-15 encoding. I don't have the power to change this encoding, so I guess we will have to deal with ANSI.
The issue is that when creating my form, I use this piece of code :
public function createAction() {
BootstrapLogger::info(__METHOD__);
$this->layout( 'layout/xhtml' );
$dbAdapter = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter');;
$form = new ActionForm($dbAdapter);
$form->get('submit')->setValue('Créer');
}
and get this error :
Message:
String to be escaped was not valid UTF-8 or could not be converted: Crï¿œer
I don't really understand why, nor how to avoid this.
As I'm guessing it's the same reason that, when creating my form, the labels are also wrongly encoded.
$this->add( array(
'name' => 'act_num',
'type' => 'Text',
'options' => array(
'label' => "N° action",
),
'attributes' => array(
'disabled' => 'disabled',
'class' => 'form-control'
)
));
//ch2 - Libellé de l'action
$this->add( array(
'name' => 'act_label',
'type' => 'Text',
'options' => array(
'label' => "Libellé de l'action",
),
'attributes' => array(
'required' => 'required',
'class' => 'form-control'
)
));
This will give me
Nￜ action
Libellￜ de l'action
Same issue with the content of the select (that are populated by the SQLDb [that is in latin1_general_ci]).
Any idea how to fix this ?
Many thanks in advance
Try specifying a different encoding for your form. Not sure how you use your InputFilter, because there are few different ways, but add this for every field.
'validators' => [
[
'name' => 'StringLength',
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
],
],
],

I'm using an Image Captcha and I want to customize the "Captcha value is wrong" error message.
This is the definition of my Captcha:
$captcha = new ImageCaptcha();
$font = "./data/fonts/calibri.ttf";
$captcha->setFont($font);
$captcha->setDotNoiseLevel(55);
$captcha->setLineNoiseLevel(3);
In my form's constructor:
$this->add(array(
'type' => 'Zend\Form\Element\Captcha',
'name' => 'captcha',
'options' => array(
'label' => 'Please verify you are human.',
'captcha' => $this->captcha,
'messages' => array(
\Zend\Captcha\Image::BAD_CAPTCHA => 'super neat captcha message.',
),
),
));
I also tried:
$this->add(array(
'type' => 'Zend\Form\Element\Captcha',
'name' => 'captcha',
'options' => array(
'label' => 'Please verify you are human.',
'captcha' => $this->captcha,
'messages' => array(
\Zend\Captcha\AbstractWord::BAD_CAPTCHA => 'super neat captcha message.',
),
),
));
But I keep getting the "Captcha value is wrong" message.
The "message" part has to be in the captcha-options like this:
$this->add([
'type' => 'Zend\Form\Element\Captcha',
'name' => 'captcha',
'options' => [
'label' => 'Please verify you are human.',
'captcha' => [
...
'messages' => [
\Zend\Captcha\Image::BAD_CAPTCHA => 'super neat captcha message.',
],
],
],
]);
At least it works for me with Zend Framework 3.
Adding captcha element:
$this->add(array(
'type' => 'Zend\Form\Element\Captcha',
'name' => 'captcha',
'options' => array(
'label' => 'Please verify you are human.',
'captcha' => $this->captcha
),
));
And error message:
$this->getInputFilter()->get('captcha')->setErrorMessage('super neat captcha message.');
It works for me.
I am migrating an application from Zend 1 to Zend 2 and starting to desperate with one issue. The application works with different locales and therefore, I need to store the data in a normalized way in the database. In Zend 1 I used this code:
public function normalizeNumber( $value )
{
// get the locale to change the date format
$this->_locale = Zend_Registry::get('Zend_Locale' );
return Zend_Locale_Format::getNumber($value, array('precision' => 2, 'locale' => $this->_locale));
}
Unfortunately Zend 2 does not has this Zend_Locale_Format::getNumber any more and I was not able to figure out what function did replace it. I have tried with NumberFormat, but I get only localized data not normalized. I need this function to normalize data I receive from a form via POST. Can someone give some advice?
thanks
Just to complete my question. The Form element definition I am using is the following:
namespace Profile\Form;
use Zend\Form\Form;
use Zend\InputFilter\InputFilterProviderInterface;
class Profile Extends Form implements InputFilterProviderInterface
{
protected $model;
public function __construct( $model, $name = 'assignmentprofile')
{
parent::__construct( $name );
$this->setAttribute( 'method', 'post');
$this->model = $model;
...
$this->add( array(
'name' =>'CommutingRate',
'type' =>'Zend\Form\Element\Text',
'options' => array( // list of options to add to the element
'label' => 'Commuting rate to be charged:',
'pattern' => '/[0-9.,]/',
),
'attributes' => array( // Attributes to be passed to the HTML lement
'type' =>'text',
'required' => 'required',
'placeholder' => '',
),
));
}
public function getInputFilterSpecification()
{
return array(
...
'CommutingRate' => array(
'required' => true,
'filters' => array(
array( 'name' => 'StripTags', ),
array( 'name' => 'StringTrim'),
array( 'name' => 'NumberFormat', 'options' => array('locale' => 'en_US', 'style' => 'NumberFormatter::DECIMAL', 'type' => 'NumberFormatter::TYPE_DOUBLE',
))
),
'validators' => array(
array( 'name' => 'Float',
'options' => array( 'messages' => array('notFloat' => 'A valid numeric entry is required')),
),
),),
...
);
}
}
As mentioned before, I am able to localized the data and validate it in the localized manner, but i am failing to convert it back to a normalized manner...
I'm working on a module and I would like to know how to add multiple dropdown with fields_options.
$this->fields_options = array(
'Test' => array(
'title' => $this->l('Test'),
'icon' => 'delivery',
'fields' => array(
'IXY_GALLERY_CREATION_OCCASION' => array(
'title' => $this->l('DropdownList'),
'type' => 'select',
'multiple' => true , // not working
'identifier' => 'value',
'list' => array(
1 => array('value' => 1, 'name' => $this->l('Test 1 ')),
2 => array('value' => 2, 'name' => $this->l('Test 2)'))
)
),
),
'description' =>'',
'submit' => array('title' => $this->l('Save'))
)
);
This is how I'm doin if you're meaning that :
$combo = $this->getAddFieldsValues();
$fields_form = array(
'form' => array(
'legend' => array(
'title' => $this->l('Title'),
'icon' => 'icon-cogs'
),
'input' => array(
array(
'type' => 'select',
'lang' => true,
'label' => $this->l('Nom'),
'name' => 'nom_matiere',
'options' => array(
'query' => $combo[0],
'id' => 'id_option',
'name' => 'name'
)
),
array(
'type' => 'select',
'lang' => true,
'label' => $this->l('Nom'),
'name' => 'name',
'options' => array(
'query' => $combo[1],
'id' => 'id_option',
'name' => 'name'
)
),
),
),
'submit' => array(
'title' => $this->l('Save'),
'name' => $this->l('updateData'),
)
),
);
the answer are not correctly .. due its not only dfined the field in the database, also must capture and stored in special way the values, in this example i demostrate to store as "1,2,3,6,8" using a single field
THE COMPLETE CODE AND ALL THE STEPS ARE AT: https://groups.google.com/forum/m/?hl=es#!topic/venenuxsarisari/z8vfPsvFFjk
here i put only the most important parts..
as mentioned int he previous link, added a new fiel in the model definition, class and the table sql
this method permits to stored in the db as "1,2,3" so you can use only a single field to relation that multiple selected values, a better could be using groupbox but its quite difficult, take a look to the AdminCustomers controller class in the controllers directory of the prestachop, this has a multiselect group that used a relational table event stored in single field
then in the helper form list array of inputs define a select as:
at the begining dont foget to added that line:
// aqui el truco de guardar el multiselect como una secuencia separada por comas, mejor es serializada pero bueh
$this->fields_value['id_employee[]'] = explode(',',$obj->id_employee);
this $obj are the representation of the loaded previous stored value when go to edit ... from that object, get the stored value of the field of your multiselect, stored as "1,3,4,6"
and the in the field form helper list of inputs define the select multiple as:
array(
'type' => 'select',
'label' => $this->l('Select and employee'),
'name' => 'id_employee_tech',
'required' => false,
'col' => '6',
'default_value' => (int)Tools::getValue('id_employee_tech'),
'options' => array(
'query' => Employee::getEmployees(true), // el true es que solo los que estan activos
'id' => 'id_employee',
'name' => 'firstname',
'default' => array(
'value' => '',
'label' => $this->l('ninguno')
)
)
),
an then override the post process too
public function postProcess()
{
if (Tools::isSubmit('submitTallerOrden'))
{
$_POST['id_employee'] = implode(',', Tools::getValue('id_employee'));
}
parent::postProcess();
}
this make stored in the db as "1,2,3"
I am adding a consent checkbox to an existing form. I am not able to render the label to the right of the checkbox. What am I doing wrong?
Please note that the check box has created using $this->addElement( because the rest of the form was created this way.
I thank you in advance.
$this->addElement('checkbox', 'isUserConsent', array(
'options' => array(array('placement' => 'APPEND')),
'label' => 'Plz activate',
'validators' => array(
array('InArray', false, array(
'hay' => array(1),
'messages' => 'Please check the consent box'),
)
),
'decorators' => array('ViewHelper','Errors','Label'),
));
The default is to prepend the label, but you can change this by modifying the decorator's 'placement' option:
$this->getElement('isUserConsent')->getDecorator('label')->setOption('placement', 'append');
Edit: I never use this syntax for decorators but it should be something like this:
$this->addElement('checkbox', 'isUserConsent', array(
'options' => array(array('placement' => 'APPEND')),
'label' => 'Plz activate',
'validators' => array(
array('InArray', false, array(
'hay' => array(1),
'messages' => 'Please check the consent box'),
)
),
'decorators' => array(
'ViewHelper',
'Errors',
'Label' => array(
'placement' => 'append'
)
),
));
This is the code for rendering lable of a form element.
$this->form->name->renderLabel() ;
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],
],
],
],
])
