I want to create multi-level embed form in symfony 1.4.
I have three forms:
1 - Question form,
2 - Option form and
3 - answer form.
In that, one question have many options fields and one option have many answers fields.
When I tried to add one more field in option criteria by rendering the HTML for answer fields using ajax and try to save form that time I am getting error Unexpected extra form field named "1"
And I have embedded Option form in Question form and Answer form in Option form respectively.
The below error is produce after submit form :
pick_type_option [0 [pick_type_answers [Unexpected extra form field named "1".]]]
Can any one please help me to find out the solution for this problem.
In advanced thanks
As it's unknown how many Option forms will be there during construction of the form (inside configure(), you have to override bind() method and add as many as needed:
class QuestionForm extends sfForm {
public function configure() {
$this->embedFormArray('question', new OptionForm);
}
private $formArray = array();
public function embedFormArray($name, \sfForm $form, $decorator = null, $innerDecorator = null, $options = array(), $attributes = array(), $labels = array()) {
$this->formArray[] = array($name, $form, $decorator, $innerDecorator, $options, $attributes, $labels);
}
public function bind(array $taintedValues = null, array $taintedFiles = null) {
foreach($this->formArray as $fa) {
$c = (isset($taintedValues[$fa[0]]) ? count($taintedValues[$fa[0]]) : 0);
array_splice($fa, 2, 0, [$c]);
call_user_func_array(array($this, 'embedFormForEach'), $fa);
}
return parent::bind($taintedValues, $taintedFiles);
}
}

I'm working with project where tables are created all the time depending on user adding new properties, so for my model i have below
class Hotel extends Model
{
public function __construct($hotel)
{
$this->table = $hotel;
}
protected $fillable = ['date', 'sold', 'sold_diff', 'rev', 'rev_diff', 'row', 'date_col', 'sold_col', 'rev_col'];
}
and i can use the table in controller by doing
$hotel_table = new Hotel($table);
but i like to use Model::updateOrCreate() when I'm adding or updating rows in table, and I'm not sure how to do that.
This is the signature for the updateOrCreate function
"static Model updateOrCreate( array $attributes, array $values = array())"
For you to update or create, you can pass the condition that must be met to update the table to the first argument and the values to be updated to the second.
for example.
$primaryKey = isset($request->input('id')) ? $request->input('id') : null;
$myModel = Model::updateOrCreate(['id' => $primaryKey], $request->all());
so with this if id is in the request object the table will be updated but if not a new record will be created.
In Laravel 5.2 you can use simply like this
class Hotel extends Model
{
protect $table = 'hotels'
protected $fillable = ['date', 'sold', 'sold_diff', 'rev', 'rev_diff', 'row', 'date_col', 'sold_col', 'rev_col'];
// protected $guarded = []; you can use this instead of `$fillable` this is for all columns fillable
}
now in your controller you can use
Model::update();
Model::create();
I have multiselect jquery plagin (Choosen) and when I use it in 'Multiple Select' mode I expect in controller next values:
posted string = 'value1,value2...'
really have
posted string = 'value2'
only if I reffer directly to FormCollection I'll get expected values as below:
[HttpPost]
public ActionResult TagSearech(/*string tagSelect*/FormCollection c)
{
// only one value here
// string[] names = tagSelect.Split(',');
// as expected: value1,....
string expectedValue = c['tagSelect'];
return View();
}
I cant understand what might cause this behavior.
EDIT
Here is View:
#using (Html.BeginForm("TagSearech", "Tag"))
{
#Html.DropDownList("tagSelect", Model, new { #class = "chzn-select", data_placeholder = "tag names", multiple = "" })
<input type="submit"/>
}
MVC will attempt to bind the input data on the URL into the model. I haven't seen how Chosen.js posts the data back to the server, but essentially its coming in in the wrong format, so MVC binds the first element it sees to the string Model.
The FormsCollection retrieves all of the data that was posted in the URL, which is why all of your selected values can be seen there.
Did you try changing the incoming model from string to string[], and see if all of the items are bound to the array?
I tried this this solution, but it seams not to work in Symfony 1.4.
Has something changed? How do I add selected attribute to the form select?
Here is my form class:
// /lib/form/doctrine/CurrencyListForm.class.php
class CurrencyListForm extends BaseCurrencyForm
{
public function configure()
{
$choices = '';
$choice = Doctrine::getTable('currency')
->createQuery('a')
->execute();
foreach($choice as $v)
$choices[$v->getCurrencyCode()] = $v->getCurrencyCode();
$this->setWidgets(array(
'currency_code' => new sfWidgetFormSelect(array('choices' => $choices)),
));
}
}
And this is how I instantiate it:
$this->form = new CurrencyListForm();
What kind of form are you rendering? If it's an object form (like sfFormDoctrine), the binding 'reverts' the defaults. (It sets the defaults of the model).
What I found was the simplest way to bind it, is creating a dummy object and set the property on that object. Then pass this object to the constructor of the form.
Something like this:
$defaultCurrency = new Currency();
$defaultCurrency->currency_code = 'EUR';
$this->form = new CurrencyListForm($defaultCurrency);
I have a table, heading, that has an import_profile_id. import_profile has a bank_id.
On my headings list page in my admin, I'd like to add the ability to filter by bank_id. However, since heading doesn't have a bank_id - it needs to go through import_profile to get that - I can't just add a bank_id field and expect it to work.
Can anyone explain how to do this? The closest thing I've found is this post but I don't think it really addresses my issue.
This can be done by using virtual columns like the post you found. The virtual column is a way to add a new criteria to filter using the autogenerated filter provided by symfony. It works like this:
1 - Go to the generator.yml of the admin module and add the name of the virtual column that will create and add
<!-- apps/backend/modules/module_name/config/generator.yml -->
filter:
[virtual_column_name, and, other, filter, columns]
2 - In your lib/filter/{TableName}FormFilter.class.php (I think in your case must be HeadingFormFilter) you have to define that virtual column in the configure() method
public function configure()
{
//Type of widget (could be sfWidgetFormChoice with bank names)
$this->widgetSchema['virtual_column_name'] = new sfWidgetFormInputText(array(
'label' => 'Virtual Column Label'
));
//Type of validator for filter
$this->validatorSchema['virtual_column_name'] = new sfValidatorPass(array ('required' => false));
}
3 - Override the getFields() of that class to define it in the filter and set the filter function
public function getFields()
{
$fields = parent::getFields();
//the right 'virtual_column_name' is the method to filter
$fields['virtual_column_name'] = 'virtual_column_name';
return $fields;
}
4 - Finally you have to define the filter method. This method must be named after the add...ColumnQuery pattern, in our case must be addVirtualColumnNameColumnQuery(not a happy name choice :P), so
public function addVirtualColumnNameColumnQuery($query, $field, $value)
{
//add your filter query!
//for example in your case
$rootAlias = $query->getRootAlias();
$query->innerJoin($rootAlias . '.ImportProfile ip')
->andWhere('ip.BankId = ?', $value);
//remember to return the $query!
return $query;
}
Done! You can know filter by bank_id.
I'm trying to create a form that change the validation of a field based on the select option from the html form field.
Ex: if user select a option 1 from drop down field "options", I want the field "metric" to validate as sfValidatorInteger. If user select option 2 from field "options", I want the field "metric" to validate as sfValidatorEmail, etc.
So inside the public function configure() { I have the switch statement to capture the value of "options", and create the validator based on that value returned from the "options".
1.) How do I capture the value of "options" ? I've tried:
$this->getObject()->options
$this->getTaintedValues()
The only thing that's currently working for me is but it's not really MVC:
$params = sfcontext::getInstance()->getRequest()->getParameter('options');
2.) Once I've captured that information, how can I assign the value of "metric" to a different field? ("metric" is not a real column in db). So I need to assign the value of "metric" to different field such as "email", "age" ... Currently I'm handling this at the post validator like this, just wondering if I can assign value within the configure():
$this->validatorSchema->setPostValidator(new sfValidatorCallback(array('callback' => array($this, 'checkMetric'))));
public function checkMetric($validator, $values) {
}
Thanks!
You want to use a post validator. Try doing something like this in your form:
public function configure()
{
$choices = array('email', 'integer');
$this->setWidget('option', new sfWidgetFormChoice(array('choices' => $choices))); //option determines how field "dynamic_validation" is validated
$this->setValidator('option', new sfValidatorChoice(array('choices' => array_keys($choices)));
$this->setValidator('dynamic_validation', new sfValidatorPass()); //we're doing validation in the post validator
$this->mergePostValidator(new sfValidatorCallback(array(
'callback' => array($this, 'postValidatorCallback')
)));
}
public function postValidatorCallback($validator, $values, $arguments)
{
if ($values['option'] == 'email')
{
$validator = new sfValidatorEmail();
}
else //we know it's one of email or integer at this point because it was already validated
{
$validator = new sfValidatorInteger();
}
$values['dynamic_validation'] = $validator->clean($values['dynamic_validation']); //clean will throw exception if not valid
return $values;
}
1) In a post validator, values can be accessed by using the $values parameter. Just use $values['options'] and it should be fine... or did you want to access this values from another part of you code? $this->getObject()->widgetSchema['options'] should work too I think, once your form is bound to an object.
2) The configure() method is called at the end of the form constructor, so values are not bound nor accessible yet, unless you are initializing your form with an object from the db (which does not require any validation). But if you want to initialize your form from $_POST, a post validator is definitely the way to go IMHO.
I got the validation error to appear alongside the field by throwing a sfValidatorErrorSchema instead of a sfValidatorError.
$values['dynamic_validation'] = $validator->clean($values['dynamic_validation']);
…becomes…
try
{
$values['dynamic_validation'] = $validator->clean($values['dynamic_validation']);
}
catch(sfValidatorError $e)
{
$this->getErrorSchema()->addError($e, 'dynamic_validation');
throw $this->getErrorSchema();
}
Not sure if this is the best way to get this result, but it seems to be working for me at the moment.
