setValue() For Form Fields in Symfony

If you want to overwrite the value of a field in an action, you have to a create a new method for the form. Usually  people think that setDefault method is good for that. No. setDefault set a default value to a field. However if the field contains a value, setDefault won't overwrite it. Let's see an example: You put a word to the "location" field then you save the form to the database. after that, you want to see another value in the "location" field:

// add this method to the form class
public function setValue($field, $value) {
  // set the value for this request
  $this->values[$field] = $value; 
  // override the value entered by the user
  $this->taintedValues[$field] = $value;
  // force a refresh on the field schema
  $this->resetFormFields();
}


// actions.class.php ... save method ...
if ($this->form->isValid())
{
  $this->form->save();

  // the magic
  $this->form->setValue('location', 'a new value');

  // you can set an empty value also
  $this->form->setValue('location', '');

  // if location is a checkbox, you have to set null to uncheck it
  $this->form->setValue('location', null);

Doctrine Not Save Boolean Value to Database in Symfony

If you create a boolean field in the database and symfony renders it as a checkbox ( sfWidgetFormInputCheckbox ) in the form... AND DOCTRINE DOES NOT SAVE THE VALUE TO THE DATABASE, you have to a put the boolean validator on it and doctrine will save the value. That's the magic.

    $this->setValidators(array(
        ...,
        'enabled' => new sfValidatorBoolean(),
        ...,
    ));

To the form...

Symfony sfConfig Variables

This page was originally available here: Doggetto.com. However the page is unavailable now, thus I publish this copy.

Reference to Config Variables

• Be careful in referencing any app-specific variables in the model in a multi-app project.  If they are not available in the app you are using the model function in you will have problems.

sfConfig::get('sf_config_variable', 'The default value'); // The default is optional.

Useful jQuery Tips

Check if a checkbox is checked:
if($('#checkbox').is(':checked')) ...

Check if a select option is selected:
if($('#select option:selected').length()) ...

Get the selected radio value:
$('.radio:checked').val()

Get all inputs with a classname begins with rescheck:
  $("input[class^=rescheck-]").each(
    function() {
      alert($(this).attr('class'));
    }
  );

Jump to ( Scroll To ) an element:
$('html, body').animate({ scrollTop: $("#some_element").offset().top }, 500);

Checking to see if there is an attribute on an element:
var attr = $(this).attr('name');
if (typeof attr !== 'undefined' && attr !== false) {}

Clear selection on select:
$("#my_select option:selected").removeAttr("selected");

Ajax request and putting the result array into a select:

  $.post("/url", function(data) {
    var selected = '';
    $.each(data, function(key, data) {
      $('#foobar').append("" + data + "");
    });
  });
