Description
I need a way to make the image attach required for certain content types. Is there any support for this?
#1
there is not. you might want to look at the imagefield module for that.
#2
I ended up writing a module that implements hook_form_alter:
<?php
function mymodule_forms_form_alter($form_id, &$form)
{
switch($form_id)
{
case 'some_content_type_node_form':
if ($form['#node_type']->type != 'image')
{
$type = $form['type']['#value'];
// If enabled adjust the form.
if ($form_id == $type .'_node_form' && variable_get('image_attach_'. $type, 0))
{
// Make the image attach field required
$form['image_attach']['image']['#required'] = TRUE;
}
}
break;
}
} // End Function
?>
#3
The code above had an error - if you attached and image and submitted the content type, an error was thrown saying that the image field was required. This code here fixes the issue:
<?php
function mymodule_forms_form_alter($form_id, &$form)
{
switch($form_id)
{
case 'some_content_type_node_form':
if ($form['#node_type']->type != 'image')
{
$type = $form['type']['#value'];
// If enabled adjust the form.
if ($form_id == $type .'_node_form' && variable_get('image_attach_'. $type, 0))
{
// If an image has been attached, there will be a #value key. If it's not there, make the field required.
if(! array_key_exists('#value', $form['image_attach']['iid']))
{
// Make the image attach field required
$form['image_attach']['image']['#required'] = TRUE;
}
}
}
break;
}
} // End Function
?>

Open this up again if need be, but it seems like this is by design and you've created your own solution (and documented it here for others to find, thanks).
