In renderform I have one input field and its type is "text". How to set a value to that input field, so at every time when the form is loaded the value should be displayed. I am using Prestashop 1.7.
Sample code:
array(
'type' => 'text',
'label' => $this->l('VENDOR_SERVER_IP'),
'name' => 'serverip',
'size' => 50,
'class' => 'fixed-width-xxl',
'required' => true,
'desc' => $this->l('Please enter your server ip.')
),
You need to use the fields_value property
$helper = new HelperForm();
//...
$helper->fields_value = array(
'serverip' => 'x:x:x:x'
);
You have no option to pass default value of input field in the form array. To provide default value, you have to use fields_value property of form helper.
$hlper = new HelperForm();
$value = 'Your already saved value if any';
if (empty($value)) {
$value = 'your default value';
}
$hlper->field_values = array('YOUR_FORM_INPUT_NAME' => $value);
echo $hlper->generate($your_form_array);

Please, help me.
I'm creating a new question type (modifying gapselect question). I have some input forms in my question renderer (see screenshot below). In get_expected_data() I have:
$vars = array();
foreach ($this->places as $place => $notused) {
$vars[$this->field($place)] = PARAM_TEXT;
}
return $vars;
But it takes only numbers.
Are there ideas, what's wrong?
numbers entered
letters entered
HTML code of inputs:
$inputattributes = array(
'type' => 'text',
'name' => $inputname,
'value' => $currentanswer,
'id' => $this->box_id($qa, 'p' . $place),
'size' => 30,
'class' => 'form-control',
);
$input = html_writer::empty_tag('input', $inputattributes);
Check that the type is set to text and not to number for all the inputs
e.g.
// wrong
$mform->addElement('number', 'email', get_string('email'));
// correct
$mform->addElement('text', 'email', get_string('email'));
Alternatively check there are no rules associated with the element to enforce numeric input.
$mform->addRule('email', get_string('email'), 'numeric', ....
I m working on prestasshop and I created a helper form inside a controller (for back office). My question is how to upload a document by using the type:'file' from the helper form. Here is the code:
public function __construct()
{
$this->context = Context::getContext();
$this->table = 'games';
$this->className = 'Games';
$this->lang = true;
$this->addRowAction('edit');
$this->addRowAction('delete');
$this->bulk_actions = array('delete' => array('text' => $this->l('Delete selected'),
'confirm' => $this->l('Delete selected items?')));
$this->multishop_context = Shop::CONTEXT_ALL;
$this->fieldImageSettings = array(
'name' => 'image',
'dir' => 'games'
);
$this->fields_list = array(
'id_game' => array(
'title' => $this->l('ID'),
'width' => 25
)
);
$this->identifier = 'id_game';
parent::__construct();
}
public function renderForm()
{
if (!($obj = $this->loadObject(true)))
return;
$games_list = Activity::getGamesList();
$this->fields_form = array(
'tinymce' => true,
'legend' => array(
'title' => $this->l('Game'),
'image' => '../img/admin/tab-payment.gif'
),
'input' => array(
array(
'type' => 'select',
'label' => $this->l('Game:'),
'desc' => $this->l('Choose a Game'),
'name' => 'id_games',
'required' => true,
'options' => array(
'query' => $games_list,
'id' => 'id_game',
'name' => 'name'
)
),
array(
'type' => 'text',
'label' => $this->l('Game Title:'),
'name' => 'name',
'size' => 64,
'required' => true,
'lang' => true,
'hint' => $this->l('Invalid characters:').' <>;=#{}'
),
array(
'type' => 'file',
'label' => $this->l('Photo:'),
'name' => 'uploadedfile',
'id' => 'uploadedfile',
'display_image' => false,
'required' => false,
'desc' => $this->l('Upload your document')
)
)
);
$this->fields_form['submit'] = array(
'title' => $this->l(' Save '),
'class' => 'button'
);
return AdminController::renderForm();
}
Now how can I upload the document?
Do I have to create a column in the table of the db (games table) for storing the file or something related?
Thanks in advance
I assume this AdminController for your model. Now a model obviously can't hold a file in table column. What you can do is hold path to the uploaded file. That's what you can save.
You should look in AdminController class (which you extended). When you submit a form, one of two method are executed:
processAdd()
processUpdate()
Now investigate the flow logic in these methods. Other methods are called from within this methods, such as:
$this->beforeAdd($this->object); -> calls $this->_childValidation();
$this->validateRules();
$this->afterUpdate($object);
As you can see, there these are the methods where you can do you custom stuff. If you look up these functions in AdminController class, the're empty. They are purposely added so people can override them and put their custom logic there.
So, using these functions, you can validate your uploaded file fields (even though it isnt in the model itself), if it validates you can then assign path to the object; and then in beforeAdd method you can actually move the uploaded file to the desired location (because both child validation and default validation has passed).
The way I've done it:
protected function _childValidation()
{
// Check upload errors, file type, writing permissions
// Use $this->errors['file'] if there is an error;
protected function beforeAdd($object)
{
// create filename and filepath
// assign these fields to object;
protected function afterAdd($object)
{
// move the file
If you allow the file field to be updated, you'll need to to these steps for Update methods as well.
you can get uploaded file using $_FILES['uploadedfile'] in both the functions processAdd() and processUpdate(), you can check all the conditions there and before calling $this->object->save(); to save the form data you can write the code to upload the file in the desired location like
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)
since you can't save the file in database you need to save only the name of the file or location on the database
Hope that helps
I have a form in Zend Framework 1. when I click on edit button I want to display values from databases in the form. but I don't know how to do it.
This is my form code:
// Add an email element
$this->addElement('text', 'orgname', array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators'=>Array(
'ViewHelper','Errors'
)
));
This is my controller:
public function editclientcompanyAction()
$form = new Application_Form_Companyform();
$form->addform();
$this->view->form = $form;
$request = $this->getRequest();
$editid=$request->getParam('id');
$edit_show = new Application_Model_Clientcompany;
$showdetails = $edit_show->editclient($editid);
$this->view->assign('datas', $showdetails);
How do I display database vlaues in my Zend Form?
There are two cases.
1) Populating form which has fields same like the database table fields : If you have the form which has same fields like the database fields, then you can populate them easily.
First you need to get the data from the database and then call the Zend_Form populate function passing the data as an associative array, where keys will be same like form fields names and values will be values for the form fields, as below in case of your form.
This will be in your controller
$data = array("orgname" => "Value for the field");
$form = new Application_Form_Companyform();
$form->populate($data);
Now send will automatically populate the form field orgname. You dont need to modify your form or set the value field in the addElement.
*2)Setting field value manually: * The second case is to set the value manually. First you will need to modify your form and add a constructor to it. Also in your form class you will need to create a property (if you have multiple fields, then you can create an array property or multiple properties for each field. This will be all up to you.). And then set the value key in the addElement. Your form should look like this
class Application_Form_Companyform extends Zend_Form
{
private $orgname;
public function __contruct($orgname)
{
$this->orgname = $orgname;
//It is required to call the parent contructor, else the form will not work
parent::__contruct();
}
public function init()
{
$this->addElement('text', 'orgname',
array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators'=>Array('ViewHelper','Errors'),
'value'=>$this->orgname
)
));
} //end of init
} //end of form
Now your controller, you will need to instantiate the form object passing the value of the orgname field like below
$form = new Application_Form_Companyform("This is the value for orgname");
And thats it.
I used such methods and it works like a charm. For your requirements, you may need to adjust the above sample code, as i did not checked it, but it will run fine for sure i hope :P
Thank you
Ok in either ZF1 or ZF2 just do this.
// Add an email element
$this->addElement('text', 'orgname',
array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators' => Array('ViewHelper','Errors'),
'value' => $showdetails->orgname
)
));
You might want to test first for null/empty values first though, you could use ternary operators for convenience:
// Add an email element
$this->addElement('text', 'orgname',
array(
'required' => true,
'filters' => array('StringTrim'),
'style' => array('width:220px'),
'decorators' => Array('ViewHelper','Errors'),
'value' => empty($showdetails->orgname)? null : $showdetails->orgname
)
));
Please have a look in my edit function at /var/www/html/zend1app/application/controllers/CountryController.php :
public function editAction() {
$data = $this->getRequest()->getParams();
$id = (int)$data['id'];
$options = array();
$country = $this->getCountryModel()->fetchRow("id=$id");
if(!$country)
{
throw new Exception("Invalid Request Id!");
}
$form = new Application_Form_Country();
$form->addIdElement();
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost())){
$data = new Application_Model_Country();
if($data->save($form->getValues()))
{
$message = array("sucess" => "Country has been updated!");
}
else {
$message = array("danger" => "Country could not be updated!");
}
$this->_helper->FlashMessenger->addMessage($message);
return $this->_helper->redirector('index');
}
}
$options = array (
'id' => $country->id,
'name' => $country->name,
'code' => $country->code
);
$form->populate( $options ); // data binding in the edit form
$this->view->form = $form;
}
and form class at /var/www/html/zend1app/application/forms/Country.php :
class Application_Form_Country extends Zend_Form
{
public function init()
{
// Set the method for the display form to POST
$this->setMethod('post');
// Add an email element
$this->addElement('text', 'name', array(
'label' => 'Enter Country Name:',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add the comment element
$this->addElement('text', 'code', array(
'label' => 'Enter Country Code:',
'required' => true,
'validators' => array(
array('validator' => 'StringLength', 'options' => array(0, 20))
)
));
// Add the submit button
$this->addElement('submit', 'submit', array(
'ignore' => true,
'label' => 'Save',
));
// And finally add some CSRF protection
$this->addElement('hash', 'csrf', array(
'ignore' => true,
));
}
public function addIdElement()
{
$this->addElement('hidden', 'id');
}
}
HTH
I am using zend form. I want to validate a field and want to allow only flat and integer values in the field. It means user can either enter any floating value like 2.0 or 3.56, etc OR 4 or 7, etc. But I dont want to receive alpha numeric or alphabet input.
I have used digit validator but it only allows digits not floating number.
Can any body tell me how to put both validations together?
My code is as follows
$parent_affiliate_commission = new Zend_Form_Element_Text('parent_affiliate_commission');
$parent_affiliate_commission->setRequired(true)
->addFilter('StringTrim')
->addFilter('StripTags')
->addValidator('Digits')
->setAttrib('class', 'small')
->addValidator('StringLength', false, array(2, 100))
->setDecorators(array('ViewHelper', 'errors'))
It would be really easy to create and use a custom validator. You could validate simply by using PHP is_int and is_float functions and still do in the 'Zend way'.
By using the callback method I have validated the value in numeric.Because it will not allow the characters.
$inputFilter->add(
$factory->createInput(
array(
'name' => 'proximity',
'required' => true,
'validators' => array(
array(
'name' => 'Callback',
'options' => array(
'messages' => array(
\Zend\Validator\Callback::INVALID_VALUE => 'The proximity value should be numbers'
),
'callback' => function (
$value,
$context = array())
{
$isValid = is_numeric(
$value);
return $isValid;
}
)
)
)
)));
I have a form with 2 selects. Based on the value of the first select, it updates the values of the second select using AJAX. Doing this makes the form not being valid. So, I made the next change:
$form=$this->getAddTaskForm(); //the form
if(!$form->isValid($_POST)) {
$values=$form->getValues();
//get the options and put them in $options
$assignMilestone=$form->getElement('assignedMilestone');
$assignMilestone->addMultiOptions($options);
}
if($form->isValid($_POST)) {
//save in the database
}else {
//redisplay the form
}
Basically, I check if it is valid and it isn't if the user changed the value of the first select. I get the options that populated the second select and populate the form with them. Then I try to validate it again. However this doesn't work. Anybody can explain why? The same "value was not found in the haystack" is present.
You could try to deactivate the validator:
in your Form.php
$field = $this->createElement('select', 'fieldname');
$field->setLabel('Second SELECT');
$field->setRegisterInArrayValidator(false);
$this->addElement($field);
The third line will deactivate the validator and it should work.
You can also disable the InArray validator using 'disable_inarray_validator' => true:
For example:
$this->add( array(
'name' => 'progressStatus',
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'options' => array(
'disable_inarray_validator' => true,
),
));
Additionaly you should add you own InArray Validator in order to protect your db etc.
In Zend Framework 1 it looks like this:
$this->addElement('select', $name, array(
'required' => true,
'label' => 'Choose sth:',
'filters' => array('StringTrim', 'StripTags'),
'multiOptions' => $nestedArrayOptions,
'validators' => array(
array(
'InArray', true, array(
'haystack' => $flatArrayOptionsKeys,
'messages' => array(
Zend_Validate_InArray::NOT_IN_ARRAY => "Value not found"
)
)
)
)
));
Where $nestedArrayOptions is you multiOptions and $flatArrayOptionsKeys contains you all keys.
You may also add options to select element before checking for the form validation. This way you are insured the select value is in range.
