Zend_Form - The mimetype of file 'foto.jpg' could not be detected

Question

I have a Zend_Form with file element like this:

->addElement('file', 'image', array(
        'required' => false,
        'label' => 'Venue Image',
        'validators' => array(
            array('IsImage', false),
            array('Size', false, '2097152'),
            array('Upload', false),
        ),
    ))

And when I'm using localhost the image is uploaded successfully. But when I move to my hosting the validation error shows for image field. The mimetype of file 'foto.jpg' could not be detected. What can be the reason of this?

Answer 1

What validator is IsImage? I cannot find it in the API or the manual. Try to use either

• $element->addValidator('Mimetype', false, 'image/jpg');

or

• $element->addValidator('Extension', false, 'jpg');

Answer 2

I'd guess that you need mime extension and hosting doesn't have it installed ;)

Answer 3

same thing happened to me, this was crazy stuff, more than 2 hours trying to figure out what's wrong, here is how to fix it:

install fileinfo extension on linux:

pecl install fileinfo

then you need to add to your php.ini this line:

extension=fileinfo.so

restart your apache and you are done!

*if you server is freeBSD you have to do this:

cd /usr/ports/sysutils/pecl-fileinfo/ make install
