I would like to upload an image in a custom module. The image must be permanently saved and renamed if needed. Later I want to be able to display the image somewhere on my form or wherever I want.
My current code:
function my_module_name_new_form()
{
....
$form['icon'] = array
(
'#type' => 'file',
'#title' => t('Icon'),
'#description' => t('Click "Chose File" to select an image to upload.')
);
....
}
In the submit hook I have:
// Icon
$filename = $form_state['values']['icon'];
$dest = file_build_uri($filename);
file_save_data('My data', $dest, FILE_EXISTS_RENAME);
Nothing happens… I couldn't find any Drupal 7.x compatible modules either that somehow make life easier here.
Solution:
//----------------------------
// Icon
//----------------------------
$dest_dir = file_default_scheme() . '://';// Note: file_directory_path() was removed in Drupal 7.x. // $dest_dir contains the destination directory for the file.
$validators = array('file_validate_extensions' => array('jpg png gif'));
//Save file
if ($file = file_save_upload('icon', $validators, $dest_dir))
{
$filename = $file->filename;
$file_content = file_get_contents($dest_dir.$filename); // Fatal error: Cannot access empty property in C:\xampp\htdocs\drupal\modules\custom\achievements\achievements.module on line 446
}
else
{
form_set_error('icon', 'Could not upload file.');
}
// To display the image: // die('<IMG SRC="'.file_create_url($dest_dir.$filename).'"/>');
//----------------------------

I had to do this recently. Here is what I ended up with. Which is to save an image to an image field without using a drupal form.
