Php saves file field value when validating form returns false

Question

I work with yii form forms and I have a form like this:

<?php echo CHtml::beginForm('', 'post', array('enctype' => 'multipart/form-data')); ?> Image:<?php echo CHtml::activeFileField($model, 'image');?> <?php echo CHtml::error($model, 'image');?> Full name: <?php echo CHtml::activeTextField($model, 'fullName');?> <?php echo CHtml::error($model,'fullName'); ?> <?php echo CHtml::submitButton('save);?> <?php echo CHtml::endForm();?> 

if when a user logs in, the error in the input field becomes empty, and then the user must re-select his image .. is there a way to save the value of the file field in yii or php?

Thank you in advance

Short answer: No

The file entry depends on the user's local file system, which the server (and therefore PHP) knows nothing about. So, one form was submitted, the user will have to re-select the file. This is more of a security issue than anything else.

Here are two possible approaches to improving UX in this regard:

• The file will be uploaded successfully, so you can save it on the server and use your copy when resubmitting the form (it’s difficult to implement, potentially confusing the user, and is generally not recommended).
• (it is better). You can test your client side using Javascript or server-side through AJAX - before sending it. If you do this, you should still check the back end, but this will help provide legitimate users with a better user interface that seems to bother you.
