Ok, I need help with something that seems pretty straightforward but I just can't figure out.
I have a page in Yii into which I'm trying to embed an AJAX form. Let's call the page A. The form takes in a single value, and needs to validate and store it into the DB if it's alright.
So far, here's what I've figured out:
The form is in a view _form.php, which contains a CActiveForm and an ajaxSubmitButton which looks like this:
<?php echo CHtml::ajaxSubmitButton('submit', $this->createUrl('/site/something'), array('update'=>'#targetdiv'));?>
The form is called within another A's view like so:
<?php echo $this->renderPartial('/site/_form', array('AModel'=>$model)); //Passing some info about A ?>
In the controller's actionSomething, I'm doing the following:
if (Yii::app()->request->isAjaxRequest) {
$model = new AJAXForm('submit');
if (isset($_POST['AJAXForm'])) {
$model->attributes = $_POST['AJAXForm'];
if ($model->validate()) {
//When data's valid, save to DB is working fine. This part is working perfectly.
}
else {
//This is the part I'm confused about and that's not working
/*Trying to render the form to get the error messages and summary displayed
but nothing's showing */
$this->renderPartial('/site/_form', array('AModel'=>$model));
Yii::app()->end();
}
}
}
In Firebug, I do see that when an error is encountered, the response contains the entire partial rendered form again. However targetdiv is not getting updated with the updated form with the error messages.
I have a feeling I'm doing something wrong in actionController, but I can't figure out what. It would be helpful if I could see a full example of an AJAX submitted form as well.
Thanks!
Answer
$model->getErrors() would give you all the errors for all attributes
http://www.yiiframework.com/doc/api/1.1/CModel#getErrors-detail
if ($model->validate()) {
//When data's valid, save to DB is working fine. This part is working perfectly.
}
else {
$errors = $model->getErrors();
echo $errors;
Yii::app()->end();
}
And then pass this into ajaxSubmitButton() ajax option, according to this post on Yii forum: http://www.yiichina.net/forum/index.php/topic/23236-extension-how-to-display-validation-errors-comming-from-ajax-validation/
'success'=>"function(html) {
if (html.indexOf('{')==0) {
var e = jQuery.parseJSON(html);
jQuery.each(e, function(key, value) {
jQuery('#'+key+'_em_').show().html(value.toString());
jQuery('#'+key).addClass('clsError');
jQuery('label[for='+key+']').addClass('clsError');
});
}
