Define Media MIME Type

[saddam-azad]

Currently, you can enter an audio file into an image field because there is no way to validate whether the input is of the correct MIME Type.

Perhaps, it would be best to be able to define the input type in the code. I want users to enter just images (and not audio/video) into this field:

<?php $mb->the_field('imgurl'); ?>
<?php $mediaAccess->setGroupName('imagepost')->setInsertButtonLabel('Insert'); ?>

<p>
<?php echo $mediaAccess->getField(array(
        'name' => $mb->get_the_name(),
        'value' => $mb->get_the_value()));
 ?>     

<?php echo $mediaAccess->getButton(array('label' => 'Add Image from Library')); ?>
</p>

Maybe it is possible to leverage the post_mime_type filter of the Wordpress Media Library.

Also, would it be able to acquire the corresponding information for the file (alt, title, description)?

Cheers.
