symfony question from Javi

little children portraits taken in the studio ...

We’ve recently got the following question from newbie and thought someone may have a quick response for this to help the guy 🙂

Hi,

these are my steps first and then my question:

I have added this model and this fixture to my app :

Birthday:
  columns:
    testdate: date
 
Birthday:
  example:
    testdate: "2009-1-1"

I have generated the Birthday module. Then I’ve generated the filter
class (BirthdayFormFilter.class.php) and I have created a form filter
object in executeIndex():

$this->filter = new BirthdayFormFilter();

After that, i’ve added this lines to the index template:

<?php echo form_tag('birthday/filtrar') ?>
<?php echo $filter; ?>
<div><?php echo submit_tag('Filter') ?></div>
</form>

When i click the ‘Filter’ button i get this error:

500 | Internal Server Error | Doctrine_Connection_Mysql_Exception
SQLSTATE[HY093]: Invalid parameter number: number of bound variables
does not match number of tokens

    * at Doctrine_Query_Abstract-&gt;execute()
      in SF_ROOT_DIR/apps/frontend/modules/birthday/actions/
actions.class.php li

I know the error is produced because this:

Doctrine_Connection->execute('SELECT b.id AS b__id, b.testdate AS
b__testdate FROM birthday b WHERE b.testdate >= ? AND b.testdate
<= ?', array('month' => '1', 'day' => '2', 'year' => '2014'))

But if my steps are correct, why symfony is generating this useless clause? What am i doing wrong?Regards
