type: integer(4)
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
relations:
SectorActividadCiuTa7:
local: id_sector_actividad
foreign: id
type: one
SubsectorActividadTa8:
local: id_subsector_actividad

表 2 和表 3:

fixed: false
unsigned: false

我用 Symfony 生成了一个名为“conflictos”的模块。在这个模块中,我有一个部分 _form.php。这个部分包含一个 AJAX 函数。这里的代码:
<?php use_stylesheets_for_form($form) ?>
<?php use_javascripts_for_form($form) ?>
<?php use_helper('Date') ?>
<!--Aquí el javascript para select dependientes-->
<script type="text/javascript">
$(document).ready(function()
{
$("#conflictos1_id_sector_actividad").change(function()
{
var id_sub = $(this).val();
if(id_sub != '')
{
$.ajax
({
type: "POST",
url: '<?php echo url_for('conflictos/subsector'); ?>'+ '?id=' + id_sub,
cache: false,
data: "id_sub="+ id_sub,
success: function(data)
{
$("#conflictos1_id_subsector_actividad").html(data); // but it does not select the value of dropdown list.
}
});
}
else
{
$("#conflictos1_id_subsector_actividad").html("<option value=''>-- No se ha seleccionado subsector --</option>");
}
return false;
});
});
</script>
<form action="<?php echo url_for('conflictos/'.($form->getObject()->isNew() ? 'create' : 'update').(!$form->getObject()->isNew() ? '?id='.$form->getObject()->getId() : '')) ?>" method="post" <?php $form->isMultipart() and print 'enctype="multipart/form-data" ' ?>>
<?php if (!$form->getObject()->isNew()): ?>
<input type="hidden" name="sf_method" value="put" />
<?php endif; ?>
<table border="0" width="96%">
<tfoot>
<tr>
<td align="center" colspan="4">
<?php echo $form->renderHiddenFields(false) ?>
<a href="<?php echo url_for('conflictos/index') ?>"><button class="btn btn-success" type="button">Listado</button></a>
<?php if (!$form->getObject()->isNew()): ?>
<?php echo link_to('<button class="btn btn-danger" type="button">Borrar</button>', 'conflictos/delete?id='.$form->getObject()->getId(), array('method' => 'delete', 'confirm' => '¿Está seguro?')) ?>
<?php endif; ?>
<!--<input type="submit" value="Save" />-->
<button class="btn btn-primary" type="submit">Grabar</button>
</td>
</tr>
</tfoot>
<tbody>
<?php echo $form->renderGlobalErrors() ?>
<tr>
<td width="24%"><?php echo "<b>Sector Actividad <font color='red'> (*)</b></font><br>" ?>
<?php echo $form['id_sector_actividad']->renderError() ?>
<?php echo $form['id_sector_actividad'] ?>
</td>
<td width="24%"><?php echo "<b>Subsector Actividad</b><br> " ?>
<?php echo $form['id_subsector_actividad']->renderError() ?>
<select name="conflictos1[id_subsector_actividad]" id="conflictos1_id_subsector_actividad">
<option value="" selected="selected">Seleccione sub-sector</option>
</td>
</tbody>
</table>
</form>
AJAX 功能在我添加新记录时工作正常,但是当我要编辑记录时,与 select id_subsector_actividad 对应的字段显示为空。
我的问题是:当我使用 Symfony 调用函数 executeEdit 时,我应该在 AJAX 函数中进行哪些更改以显示字段值“id_subsector_actividad”?
