CActiveForm + iso-8859-1 = Invalid UTF-8 sequence

Yii 1.1 General Discussion

Hi!

The charset of my yii site is ‘iso-8859-1’ and I’d like to use CActiveForm.




    <?php $form=$this->beginWidget('CActiveForm', array(

                                    'id'=>'comment-form',

                                    'enableAjaxValidation'=>true,

                                    'clientOptions'=>array('validateOnSubmit'=>true, 'validateOnChange'=>false),

    )); ?>


...


    <?php $this->endWidget(); ?>

When I hit the submit button, the AJAX response is the following:




PHP Error

It seems that json_encode() was given some not UTF-8 encoded data. (according to php manual json_encode supports only utf-8)

How could I use CActiveForm with ‘charset’ => ‘iso-8859-1’?

Welcome to the encoding mismatch hell :).

Problem here is that strings in JSON objects are always UTF-8 encoded. So you need to convert back and forth between ISO-8859-1 and UTF-8 as soon as JSON is involved. Any chance you move to UTF-8 with the whole site? That would avoid such problems in the first place.

Thanks for the answer. Unfortunately I can’t change the charset of the site to UFT-8 due to compatibility reasons.

Basically I’ve to change only the CActiveForm::validate function :)

I submitted a new issue and my bugfix.
