Zend_Validate_Db_RecordExists or empty value - php

I've got a (hopefuly) simple task, and my google fu has failed me. Basically, I've got a form with a select which contains an empty value and then number of ids given content can belong to. What I want to do is - validate if the given ids exist, but only if a value is set. This:
$field = new Zend_Form_Element_Select('field');
$field->addValidator(
new Zend_Validate_Db_RecordExists(
array(
'table' => 'categories',
'field' => 'id'
)
));
takes care of the checking if the given id exists, but I'm not able to find any way to omit this if value is empty. One way to do this would be to move this logic to isValid method, but I'm hoping there's nicer way to accomplish this task.

Try to set this form element as not required:
$field->setRequired(false);
When element is not required and is not filled, validators queue won't be run.
Quick example which works for me:
// Zend_Form form body
$this->addElement('select', 'category', array(
'label' => 'Choose category',
'required' => false,
'multiOptions' => array(
null => 'No category selected',
'1' => 'One',
'2' => 'Two',
),
'validators' => array(
array('Db_NoRecordExists', false, array(
'schema' => 'public',
'table' => 'category',
'field' => 'id',
)),
),
));

Adding a dropdown menu in Prestashop 1.7 module

I'm so beginner in Prestashop 1.7, I wanted to add a dropdown select section in my banner module to select the way to open the banner link.
but the selected value is never passed to the HTML, the code below IS passed but the one under isn't, can you please assist me?
[enter image description here][1]
array(
'type' => 'text',
'lang' => true,
'label' => $this->trans('Banner description', array(), 'Modules.Banner.Admin'),
'name' => 'BANNER_DESC',
'desc' => $this->trans('Please enter a short but meaningful description for the banner.', array(), 'Modules.Banner.Admin')
)
array(
'type' => 'select', //select
'lang' => true,
'label' => $this->trans('Banner tab', array(), 'Modules.Banner.Admin'),
'name' => 'BANNER_TAB',
'required'=>'true',
'options' => array(
'query' => array(
array('key' => '_blank', 'name' => 'New tab'),
array('key' => '_self', 'name' => 'Same tab'),
),
'id' => 'key',
'name' => 'name'
),
'desc' => $this->trans('Please select the way to open the link.', array(), 'Modules.Banner.Admin')
)
This is how it looks in the Backoffice:
Here
You not only need to add a new field to your form but also handle saving the data from it.
Take a look at a few examples:
https://github.com/PrestaShop/ps_featuredproducts/blob/dev/ps_featuredproducts.php#L122
Notice how the module author managed to save each configuration field from the form. This is what you need to do.
If you want to have access to data in your view, you have to pass it:
https://github.com/PrestaShop/ps_featuredproducts/blob/dev/ps_featuredproducts.php#L244
Maybe after you added a new field, you forgot to handle the saving + passing to the view?

Nested Parameters/Values in POST Requests

I have been thinking about a good way to handle nested/complex values in POST requests to a apigility resource.
For example, an order might contain a collection of order items in a single POST requested that is used to create an order. Both, order and order-item do exist as a resource. However, I would very much like to have only one request that would create order and order item entities. Handling that in the resource is not a problem, but I wonder how you would configure that resource (let´s call it order-place) using the apigiliy UI - or, if at all impossible, using the configuration. Applying validators and filters is one of the key features of apigility, and i´d like to keep using that, even for complex request data.
And before you ask, using an underscore to separate the values scopes, for example order_comment and order_item_comment should not be an option.
Any ideas?:)
Addition: A sample json request payload could look like this:
{
"created_at": "2000-01-01",
"amount" : "5000.00",
"address" : {
"name": "some name",
"street": "some street"
...
},
"items" : [
{"productId":99,"qty":1}
...
]
}
Starting from Wilt's answer, I've found that the following code works as well:
# file path: /module/MyApi/config/module.config.php
// some other stuff
'MyApi\\V1\\Rest\\MyRestService\\Validator' => array(
'address' => array(
0 => array(
'name' => 'name',
'required' => true,
'filters' => array(),
'validators' => array(),
),
1 => array(
'name' => 'street',
'required' => true,
'filters' => array(),
'validators' => array(),
),
'type' => 'Zend\InputFilter\InputFilter'
),
'amount' => array(
'name' => 'amount',
'required' => true,
'filters' => array(),
'validators' => array()
)
The only problem I get is when address is passed as a field (string or numeric) rather then an array or object. In this case Apigility throws an exception:
Zend\InputFilter\Exception\InvalidArgumentException: Zend\InputFilter\BaseInputFilter::setData expects an array or Traversable argument; received string in /var/www/api/vendor/zendframework/zendframework/library/Zend/InputFilter/BaseInputFilter.php on line 175
Adding address as a further simple (required) field avoids the exception, but then Apigility doesn't see any difference whether we pass address as an array of name and street or a dummy string.
If you are using the ContentValidation module then you can configure an input filter for the nested resources by assigning it to a variable. Then you have to add a type key (essential otherwise reusing the filter won't work). Now you are able to use this variable in your input_filter_specs and you can reuse the whole filter inside another filter. So something like this in your config.php:
<?php
namespace Application;
// Your address config as if it was used independently
$addressInputFilter => array(
'name' => array(
'name' => 'name',
'required' => true,
'filters' => array(
//...
)
'validators' => array(
//...
)
),
'street' => array(
'name' => 'street',
'required' => true,
'filters' => array(
//...
)
'validators' => array(
//...
)
),
// 'type' key necessary for reusing this input filter in other configs
'type' => 'Zend\InputFilter\InputFilter'
),
'input_filter_specs' => array(
// The key for your address if you also want to be able to use it independently
'Application\InputFilter\Address'=> $addressInputFilter,
// The key and config for your other resource containing a nested address
'Application\InputFilter\ItemContainingAddress'=> array(
'address' => $addressInputFilter,
'amount' => array(
'name' => 'amount',
'required' => true,
'filters' => array(
//...
),
'validators' => array(
//...
)
)
//... your other fields
)
)

How can I create additional required fields for an object using jSON in Yii

I have a project to create a flexible information system. In this project I use a relational database (MySQL) and the Yii framework. Sometimes I have objects that can collect different information according to the id of the objecttype.
Basically, I have an object, which has an objecttype. In the objecttype table i have an info field which will contain a jSON with the description of the additional fields that I will require from the user at the moment of the new object creation.
http://www.bedoya.co/screenshots/object-objecttype-relation.png
Ok, now, with PHP I will collect the contents from objecttype_info (stored there as a jSON) and I will generate an array similar to this one:
<?php
$x = array(
'name' => 'Cool name to put in the fieldset label of this object type',
'fields' => array( // List of additional fields that describe this object
'field1' => array(
'label' => 'Field1 label',
'type' => 'text',
'htmlOptions' => array(
'class' => 'field1-class'
'id' => 'field1-id'
'required' => true
)
),
'campo2' => array(
'label' => 'Field2 label',
'type' => 'number',
'htmlOptions' => array(
'class' => 'field2-class'
'id' => 'field2-id'
'required' => false
)
),
)
);
Now, I get the required values with the easy function:
<?php
$x = ObjectType::model()->findByPk( $objecttype_id )->attributes[ 'objecttype_info' ];
?>
I don't know how to set the validation rules for the fields obtained from the objecttype. Any ideas? Am I doing this right?

Zend Form Validate URL

I am currently validating a URL using the Regex Pattern and it appears to be working correctly. However, if I leave the URL field blank, it should not check the Regex Validation or perhaps just return a message like "No URL given".
Here is an example of my current code I'm working with:
array(
'name' => 'programurl1',
'attributes' => array(
'type' => 'text',
'error_msg' => 'Enter Valid Program URL 1',
'label_msg' => 'Program URL 1 *'
),
'validation' => array(
'required' => true,
'filters' => array(
array(
'name' => 'StripTags'
),
array(
'name' => 'StringTrim'
)
),
'validators' => array(
array(
'name' => 'Regex',
'options' => array(
'pattern' => '/^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/'
)
)
)
)
)
I'm not certain how to accomplish what I am looking for when the URL field is blank.
Instead of a type text, you can use the url type. That is specifically meant to enter url values:
$this->add(array(
'name' => 'programurl',
'type' => 'Zend\Form\Element\Url',
'options' => array(
'label' => 'Program URL 1'
),
'attributes' => array(
'required' => 'required'
)
));
The url element is a special HTML5 element, see also the docs.
Zend\Form\Element\Url is meant to be paired with the Zend\Form\View\Helper\FormUrl for HTML5 inputs with type url. This element adds filters and a Zend\Validator\Uri validator to it’s input filter specification for validating HTML5 URL input values on the server.
Afaik if the browser cannot render the url input element, it just shows the text input as a fallback.

How to validate multiply select using Zend Framework 2

I am trying to validate a multiply select using input filter, but every time I see a error. The error is "notInArray":"The input was not found in the haystack".(I use ajax but it doesn`t metter).
I will show part of my code to be more clear.
in Controller:
if ($request->isPost()) {
$post = $request->getPost();
$form = new \Settings\Form\AddUserForm($roles);//
$form->get('positions')
->setOptions(
array('value_options'=> $post['positions']));
//.... more code...
When I put print_r($post['positions']); I see:
array(0 => 118, 1 => 119)
in ..../form/UserForm.php I create the multiply element
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'attributes' => array(
'multiple' => 'multiple',
'id' => 'choosed_positions',
),
'required' => false,
'name' => 'positions',
));
and in the validation file the code is:
$inputFilter->add($factory->createInput(array(
'name' => 'positions',
'required' => false,
'validators' => array(
array(
'name' => 'InArray',
'options' => array(
'haystack' => array(118,119),
'messages' => array(
'notInArray' => 'Please select your position !'
),
),
),
),
What can be the reason every time to see this error, and how I can fix it?
By default selects have attached InArray validator in Zend Framework 2.
If you are adding new one - you will have two.
You should disable default one as follow:
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'options' => array(
'disable_inarray_validator' => true, // <-- disable
),
'attributes' => array(
'multiple' => 'multiple',
'id' => 'choosed_positions',
),
'required' => false,
'name' => 'positions',
));
And you should get rid of the additional error message.
Please let us know if that would helped you.
