symfony1 - Outputting required field indicator for symfony forms -

-

i have few forms configured in symfony. 1 things need have asterisk (*) or other indicator next fields required. fields set required int form framework, , return "this field required" error when form submitted, want indicator before form submitted.

if there way without overriding labels each field manually?

here's automatic solution found in kris wallsmith's blog:

lib/formatter/requiredlabelsformattertable.class.php, add 'required' class labels of required fields

<?php  class requiredlabelsformattertable extends sfwidgetformschemaformattertable {   protected     $requiredlabelclass = 'required';    public function generatelabel($name, $attributes = array())   {     // loop find "required_fields" option     $widget = $this->widgetschema;     {       $requiredfields = (array) $widget->getoption('required_fields');     } while ($widget = $widget->getparent());      // add class (non-destructively) if field required     if (in_array($this->widgetschema->generatename($name), $requiredfields)) {       $attributes['class'] = isset($attributes['class']) ?         $attributes['class'].' '.$this->requiredlabelclass :         $this->requiredlabelclass;     }      return parent::generatelabel($name, $attributes);   } }

lib/form/baseform.class.php, common base class forms in project:

  protected function getrequiredfields(sfvalidatorschema $validatorschema = null, $format = null)   {     if (is_null($validatorschema)) {       $validatorschema = $this->validatorschema;     }      if (is_null($format)) {       $format = $this->widgetschema->getnameformat();     }      $fields = array();      foreach ($validatorschema->getfields() $name => $validator) {       $field = sprintf($format, $name);       if ($validator instanceof sfvalidatorschema) {         // recur         $fields = array_merge(           $fields,           $this->getrequiredfields($validator, $field.'[%s]')         );       } else if ($validator->getoption('required')) {         // field required         $fields[] = $field;       }     }      return $fields;   }

add following few lines baseform well, in __construct() method:

$this->widgetschema->addoption("required_fields", $this->getrequiredfields()); $this->widgetschema->addformformatter('table',   new requiredlabelsformattertable($this->widgetschema) );

after this, labels have required class, use whatever css need mark user.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
