Showing validation errors for specific input field

Question

I have a form set up with a file upload for profile pictures, and I'm validating the file upload like so:

'picture' => array(
    'kosher' => array(
        'rule' => 'validateImage',
        'message' => 'Only images are allowed to be uploaded'
    ),
    'size' => array(
        'rule' => array('fileSize', '<=', '2MB'),
        'message' => 'Picture must be less than 2 MB'
    )
)

The validation runs, and works, however no validation errors are shown on the form when I submit incorrect data. I'm building the entire form like so:

<?php echo $this->Form->create('Profile', array('type' => 'file')); ?>
<?php echo $this->Form->hidden('id'); ?>
<?php echo $this->Form->label('Profile.picture', 'Profile picture'); ?>
<?php echo $this->Form->file('picture'); ?>
<?php echo $this->Form->input('firstname'); ?>
<?php echo $this->Form->input('lastname'); ?>
<?php echo $this->Form->input('email', array('between' => 'This is the email other users will use to contact you')); ?>
<?php echo $this->Form->input('Skill', array('type' => 'text', 'value' => $skills, 'label' => 'Your skills (seperate each skill by space)')); ?>
<?php echo $this->Form->input('course'); ?>
<?php echo $this->Form->input('bio'); ?>
<?php echo $this->Form->end('Save changes'); ?>

The other fields error messages get shown correctly, just not the file upload. How can I make the validation errors show up around the file input?

'picture' is defined as an array for <?php echo $this->Form->file('picture'); ?> but not size. Far as I can tell. — Funk Forty Niner

Your 'size' is not being echo'ed anywhere, as compared to 'picture', 'firstname' etc. Isn't the error message for the file upload 'message' => 'Picture must be less than 2 MB'? — Funk Forty Niner

Maybe you need to add <?php echo $this->Form->file('size'); ?> somewhere. Then again, I may be wrong. — Funk Forty Niner

You have used $this->Form->file('picture'); which will only generate the file upload field nothing else.

Either add a $this->Form->error('picture'); below it which will show the validation error message or use $this->Form->input('picture', array('type' => 'file')); to generate the file upload input also.

Form::input() is a wrapper method which generates the required input field, label tag and shows validation error message if any. Please read the manual.

You'll probably have to specify the type of input to use for the 'picture' field, because the CakePHP FormHelper will not automatically create file inputs; i.e. echo $this->Form->input('picture', array('type' => 'file'));

Right, forgot to mention this. Need to specify the 'type' => 'file' as it cannot be automatically inferred. I updated my original answer accordingly.
