I am trying to add a file upload field to all story node forms. I tested the code and I am successfully getting the file upload field on the form.
$form['my_file_upload'] = array(
'#attributes' => array('enctype' => 'multipart/form-data'),
'#type' => 'file',
'#title' => t('Image'),
'#description' => t('Image should be of minimum 50x50px width and should be of type png or jpg'),
'#collapsible' => TRUE,
'#collapsed' => TRUE,
'#size' => 48,
'#weight' => 4,
);
Now the question is How do I validate the file and also how do I retrieve the file after it has passed validation?
