First, Marijn & Nicolas, thanks for sharing your time and code.
Following Nicolas' implementation I used a new Formatter to be able to
apply a CSS rule on the label:
class sfWidgetFormSchemaFormatterTable2 extends
sfWidgetFormSchemaFormatter
{
protected
$rowFormat = "<tr%required%>\n <th>%label%</th>\n <td>
%error%%field%%help%%hidden_fields%</td>\n</tr>\n",
$errorRowFormat = "<tr><td colspan=\"2\">\n%errors%</td></tr>\n",
$helpFormat = '<br />%help%',
$decoratorFormat = "<table>\n %content%</table>";
public function formatRow($label, $field, $errors = array(), $help =
'', $hiddenFields = null)
{
return strtr($this->getRowFormat(), array(
'%required%' => strstr($field, 'required') ? '
class="required"' : '',
'%label%' => $label,
'%field%' => $field,
'%error%' => $this->formatErrorsForRow($errors),
'%help%' => $this->formatHelp($help),
'%hidden_fields%' => is_null($hiddenFields) ? '%hidden_fields
%' : $hiddenFields,
));
}
}
Is it too hackish for symfony standard ? :)
Ideally I would like to have the required class to be set at the
parent node of label and input|select in order to use those CSS rules:
form .required label {font-weight:bold;}
form .required label:after {content:"*";}
form label {font-weight:normal;}
which should work for list , table and div Formatter.
Also in handleRequiredFields() how could we loop through pre and post
validator ?
For example: sfGuardUserForm set the option required for the field
password on the postValidator()

Marc Carlucci
