Hi!
I have been reading tha 'ajax integration' chapter from symfony book,
but i haven't figured out how to make it work.
The thing is:
I want that when i select something in a combo box (1st. combo) the
options in the 2th. combo change.
Until now i have this.
First i have de form:
$this->form = new DenunciaForm()
--- inside this form i have an embedded form
$denunciante = new PersonaForm()
--- inside this embedded form i have two combo box
> $this->widgetSchema['estado_id'] = new sfWidgetFormPropelChoice(
> array(
> 'model' => 'Estado',
> 'add_empty' => false,
> 'order_by' => array('Nombre', 'asc'),
> 'default' => $estado_id->getId(),
> ),
> array(
> 'onchange' => 'getMisMunicipios(this.value)',
> )
> );
> $this->widgetSchema['municipio_id'] = new sfWidgetFormPropelChoice(
> array(
> 'model' => 'Municipio',
> 'add_empty' => false,
> 'order_by' => array('Nombre', 'asc'),
> 'criteria' => $criteria_mun,
> )
> );
Here, everything good, the combos take the 'onchange' function
perfectly, (but not the default)
here my HTML:
<select onchange="getMisMunicipios(this.value)"
name="denuncia[denunciantes][estado_id]"
id="denuncia_denunciantes_estado_id">
<option value="2">Apure</option>
<option value="1">Aragua</option>
<option value="3">Carabobo</option>
</select>
<select onchange="getMisParroquias(this.value)"
name="denuncia[denunciantes][municipio_id]"
id="denuncia_denunciantes_municipio_id">
<option value="2">Libertador</option>
<option value="3">Naguanagua</option>
<option value="1">Valencia</option>
</select>
Now, i test the javascript:
> <?php use_helper('Javascript') ?>
> <?php echo javascript_tag("
> function getMisMunicipios(id)
> { alert(id) }
>
> ") ?>
and this work perfectly, The problem is that i dont understand how to
fill the second combo box with new values when i select something
different in the 1st one.
THANKS!!!!
