"Required."

The 'required' validation checks to make sure the component has a value.

                'validationOptions' => array('required'),
            

In some cases, you may wish to use 'matches' in a setting where there can be more than one instance of a section that contains both the original field and the field you want to match against. In this case, 'matches' must be assigned to an associate array that contains two keys. The first key, 'matches' receives an HTML ID (without the #) of the particular field that you wish to match a value against. The second key, 'sectionInstances' receives a boolean indicating whether or not the value you want to match against is a member of a section that can have more than one instance. For example:

                'validationOptions' => array(
                    'matches' => array(
                        'matches' => 'password',
                        'sectionInstances' => true
                    )
                ),
            

"Must have the 'user defined' extension."

The 'extension' validation takes a value a determined extension and checks to make sure the file selected has that extension.

                'validationOptions' => array('extension' => 'txt'),
            

"Incorrect file type."

The 'extensionType' validation makes sure the file selected is of the correct type, types are:

• image: bmp, gif, jpg, png, psd, psp, thm, tif
• document:doc, docx, log, msg, pages, rtf, txt, wpd, wps
• audio:aac, aif, iff, m3u, mid, midi, mp3, mpa, ra, wav, wma
• video:3g2, 3gp, asf, asx, avi, flv, mov, mp4, mpg, rm, swf, vob, wmv
• web:asp, css, htm, html, js, jsp, php, rss, xhtml
• custom:rather than setting a string you can set a custom array of extensions

                'validationOptions' => array('extensionType' => 'image'),
            

"File must be smaller then [sizelimit]kb. File is [filesize]kb."

The 'size' validation takes a integer and checks it against the file size (in kb) of the uploaded file (server side only).

                'validationOptions' => array('size' => 1024),
            

if file is not am image:

"File is not a valid image file."

if image is larger than dimensions given:

"Image must be less then [width]px wide. File is [imagesize]px."

"Image must be less then [height]px tall. File is [imagesize]px."

The 'imageDimensions' validation takes an array with keys of 'width' and 'height' and checks the image size against these values.(server side only)

                'validationOptions' => array('imageDimensions' => array('width' => 800, 'height' => 600)),
            

if file is not am image:

"File is not a valid image file."

if image is smaller than dimensions given:

"Image must be more then [width]px wide. File is [imagesize]px."

"Image must be more then [height]px tall. File is [imagesize]px."

The 'minImageDimensions' validation takes an array with keys of 'width' and 'height' and checks the image size against these values.(server side only)

                'validationOptions' => array('minImageDimensions' => array('width' => 800, 'height' => 600)),
