Error 400 Invalid request YII for deleting a record

Question

I am trying to delete a record in Yii, which throws a Error 400. Please do not repeat this request again. It's checking for a post variable, my controller file has
if(Yii::app()->request->isPostRequest)
When I echo my post variable it's blank whereas $_GET has the id which I want to delete, my View file looks like,

echo CHtml::link(CHtml::encode('Delete image'), array('image/delete', 'id'=>$image->id), array('class' => 'delete','confirm'=>'This will remove the image. Are you sure?'));

The access rules has delete to authenticated users, which is right. Tried it with a * too. I also tried sending it as a hidden variable but no good.

Not able to figure out how should I post a form in Yii.

Solution 1

This is happening because it's not a post request. CHtml::link has a way by which you can use post method, instead of get. This requires you to use submit attribute of clientChange, in your htmlOptions.

Somewhat like this:

echo CHtml::link(CHtml::encode('Delete image'), array('image/delete', 'id'=>$image->id),
  array(
    'submit'=>array('image/delete', 'id'=>$image->id),
    'class' => 'delete','confirm'=>'This will remove the image. Are you sure?'
  )
);

Solution 2

the default with Curd will be like this

/**
 * @return array action filters
 */
public function filters()
{
    return array(
        'accessControl', // perform access control for CRUD operations
        'postOnly + delete', // we only allow deletion via POST request
    );
}

The delete action can only accessed by POST; You can check it.

So you need to delete this line to work with you 'postOnly + delete',

Solution 3

According to my experience this caused by some javascript files loaded after jquery. If you have jQuery link at the end of the document please remove it.

Thanks.. It worked. :) So, all defaults are 'Get' in Yii, right? Wheneer, I need to post a form, i explicitly need to define it, the way you showed it?

by default, links are supposed to be 'Get' always, be it yii or simple html. but yes when we need to post through a link, this is the way in yii, it attaches a small javascript line to the output, which submits the form. but if you are talking about full fledged forms, take a look at cactiveform.
