I have the following input filter:
'term' => array(
'required' => false,
'filters' => array(
array(
'name' => 'StringTrim',
)
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'max' => 128
)
)
)
),
I need to get programmatically from a form object the value of the 'max' option inside the 'validators' property.
$vc = $form->getInputFilter()->get('term')->getValidatorChain()->getValidators();
foreach($vc as $v){
if($v['instance'] instanceof \Zend\Validator\StringLength)
$max = $v['instance']->getMax();
}

I have got a fieldset implementing InputFilterProviderInterface, so it has the function getInputFilterSpecification. The __construct() function is adding a file element ('logo') like so:
$this->add(array(
'name' => 'logo',
'type' => 'file',
'attributes' => array(
'required' => false,
'class' => 'form-control',
'id' => 'logo',
),
'options' => array(
'label' => 'Company Logo: ',
),
));
In my getInputFilterSpecification function how do I add the RenameUpload input filter?
I have tried several variations of the following without success:
public function getInputFilterSpecification()
{
return array(
array(
'name' => 'logo',
'filterchain' => array(
'name' => 'filerenameupload',
'options' => array(
'target' => '/public/images/' . time(),
),
),
'required' => false,
),
//... other filters
}
}
How do I add the FileRenameUpload filter (Zend\Filter\File\RenameUpload)?
[edit]
I have changed the array to:
array(
'name' => 'logo',
'filters' => array(
array(
'name' => 'filerenameupload',
'options' => array(
'target' => '/public/images/' . time(),
),
),
),
'required' => false,
),
Which "appears" to be working, however I am now getting this message -
File 'C:\xampp\tmp\phpDA68.tmp' could not be renamed. An error
occurred while processing the file.
What errors could have occurred? How do I fix it?
This issue is being caused by specifying an invalid target. Prefixing it with getcwd() makes the path relative to the application root.
array(
'name' => 'logo',
'filters' => array(
array(
'name' => 'filerenameupload',
'options' => array(
'target' => getcwd() . '/public/images/' . time(),
),
),
),
'required' => false,
),
You must have created dir before use renameFile.
Example:
mkdir( $rootPath . '/public/images/' . time() );
there is a more than strange behavior of filterInput, the getting filter function itself is:
public function getInputFilter($id = null){
if (!$this->inputFilter){
$inputFilter = new InputFilter();
$factory = new InputFactory();
$id = intval($id);
$inputFilter->add($factory->createInput(array(
'name' => 'name',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
array(
'name' => 'Db\NoRecordExists',
'options' => array(
'field' => 'name',
'table' => 'table',
'adapter' => $this->dbAdapter,
'message' => 'record exists',
'exclude' => array(
'field' => 'id',
'value' => $id
)
),
)
),
)));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
setting the filter like:
$form->setInputFilter($model->getInputFilter($id));
Now, when we fire $form->isValid(), the validation error will rise about duplication in the database, if I will remove Db\NoRecordExists validator, the database will contain 2 records! more interesting, if I will set 'required' => false, there will be no double inserting, the same with adding second validation field. Working settings are:
public function getInputFilter($id = null){
if (!$this->inputFilter){
$inputFilter = new InputFilter();
$factory = new InputFactory();
$id = intval($id);
$inputFilter->add($factory->createInput(array(
'name' => 'name',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
array(
'name' => 'Db\NoRecordExists',
'options' => array(
'field' => 'name',
'table' => 'table',
'adapter' => $this->dbAdapter,
'message' => 'record exists',
'exclude' => array(
'field' => 'id',
'value' => $id
)
),
)
),
)));
//test field
$inputFilter->add($factory->createInput(array(
'name' => 'id',
'required' => false,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
array('name' => 'Int')
),
)));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
So it fails to work correctly with filter config for only one field.. Does anybody knows the reason?
In \Zend\Validator\DateStep, I want to override the error message shown below:
protected $messageTemplates = array(
self::NOT_STEP => "The input is not a valid step"
);
I have an input filter connected to a form containing an element of the type 'Zend\Form\Element\Date' which automatically calls the DateStep validator.
Here is the relevant part of my form:
$this->add(array(
'type' => 'Zend\Form\Element\Date',
'name' => 'appointment-date',
'options' => array(
'label' => 'Appointment Date',
'format' => 'Y-m-d'
),
'attributes' => array(
'min' => date('Y-m-d'), // today's date
'max' => '2020-01-01',
'step' => '2', // days; default step interval is 1 day
)
));
Here is my input filter:
$inputFilter->add($factory->createInput(array(
'name' => 'appointment-date',
'required' => false,
'filters' => array(
array('name' => 'StripTags'),
),
'validators' => array(
array(
'name' => 'DateStep',
'options' => array(
//'step' => new DateInterval("P2D"),
//'baseValue' => new DateTime(),
'messages' => array(
\Zend\Validator\DateStep::NOT_STEP => 'Must be a day in the future',
),
),
),
),
)));
The inputFilter seems to be ignored. I tried setting up the step and baseValue in the inputFilter, but that seems to not work at all. Working app can be found here: https://github.com/bickerstoff/zf2_datetest if more details are needed.
Looks like you're trying to filter a "Date" input with a "DateStep" validator.
$this->add(array(
'type' => 'Zend\Form\Element\Date',
'name' => 'appointment-date',
'options' => array(
'label' => 'Appointment Date',
'format' => 'Y-m-d'
),
'attributes' => array(
'min' => date('Y-m-d'), // today's date
'max' => '2020-01-01',
'step' => '2', // days; default step interval is 1 day
)
));
This may cause your problem.
In a Zend Framework 2 application, I have the following form in my controller action method:
public function testAction()
{
$form = new \Zend\Form\Form('test');
$date = new \Zend\Form\Element\DateSelect('date');
$date->setOptions(array(
'label' => 'Date',
'min_year' => date('Y') - 10,
'max_year' => date('Y') + 10,
)
);
$date->getDayElement()->setEmptyOption('day');
$date->getMonthElement()->setEmptyOption('month');
$date->getYearElement()->setEmptyOption('year');
$form->add($date);
$form->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'submit',
'id' => 'submitbutton',
),
));
if ($this->request->isPost()) {
$data = $this->request->getPost();
$form->setData($data);
if ($form->isValid()) {
$data = $form->getData();
// more code
}
}
return array('form' => $form);
}
Now if I submit the form I get the validation message:
'The input does not appear to be a valid date'
That is correct but I would only want to know if the field is required. If I look in the source of the DateSelect element, I see a getInputSpecification() method that sets required to false by default and there also is a getValidator() method requiring a format with which the empty date does not comply.
How can I bypass validation if the input is not required (obviously, in my real form I have more elements)?
I usually use the factory pattern and you can set whether the field is required ie
$inputFilter->add($factory->createInput(array(
'name' => 'availableDate',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'max' => 20,
),
),
),
)));
refer the field required - you can set this to false
I am trying to customize the default error message "Value is required and can't be empty"
in zf2
I am using following code to add customise default error message in validators of inputfilter
$inputFilter->add($factory->createInput(array(
'name' => 'username',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 4,
'max' => 20,
'messages' => array(
'isEmpty' => 'Please enter User Name between 4 to 20 character!'
),
),
),
),
)));
But I am getting following error.
Zend\Validator\Exception\InvalidArgumentException
File:
/home/website/vendor/zendframework/zendframework/library/Zend/Validator/AbstractValidator.php:220
Message:
No message template exists for key 'isEmpty'
What I am doing wrong?

try this

Other validator set
You also can set the error message of inputFilter so:
$form = new ParticipantForm();
$mailInput = new Input('mail');
$mailInput->setRequired(true);
$mailInput->setErrorMessage("Empty input");
The StringLength validator does not check for the input to be empty or not. It checks against lengths. Following message templates exist for StringLength validator:
const INVALID = 'stringLengthInvalid';
const TOO_SHORT = 'stringLengthTooShort';
const TOO_LONG = 'stringLengthTooLong';
/**
* #var array
*/
protected $messageTemplates = array(
self::INVALID => "Invalid type given. String expected",
self::TOO_SHORT => "The input is less than %min% characters long",
self::TOO_LONG => "The input is more than %max% characters long",
);
See the example of #Developer for a direct approach. Though i suggest going with the CamelCased naming of the Validators, so 'name' => 'NotEmpty' instead of 'name' => 'not_empty'
You can check which messageTemplates exist if you see the code for each of the validator classes. You will find them under ./vendor/zendframework/zendframework/library/Zend/Validator/*
