I created an image node type using the CCK module imagefield. Here is how you can show a preview of the image being deleted on the confirmation page:
<?php
function MYMODULE_form_alter ( $form_id , & $form ) {
// ...code...
if ( $form_id == 'node_delete_confirm' ) {
_MYMODULE_form_alter_node_delete_confirm_user_image ( $form );
}
// ...code...
}
function _MYMODULE_form_alter_node_delete_confirm_user_image ( & $form ) {
// NOTE: This function assumes the file system path is set to private, which is needs to be for this application
$node = node_load ( arg ( 1 ));
if ( $node -> type != 'user_image' ) return ;
$maxDimension = 300 ;
$imagePath = file_create_path ( $node -> field_user_image [ 0 ][ 'filepath' ]);
// NOTE: this is a simple function I created that accepts 2 parameters (an image page and a maximum dimension) and it returns resized image dimensions
$imageDimensions = _MYMODULE_images_resize ( $imagePath , $maxDimension );
// create image html
$img = "<img style='margin: 25px;' width=' { $imageDimensions [ 'width' ] } ' height=' { $imageDimensions [ 'height' ] } ' src='/system/files/" . $node -> field_user_image [ 0 ][ 'filename' ] . "' />" ;
// add image to form
$form [ 'image_preview' ] = array (
'#value' => $img ,
'#weight' => 10 ,
);
}
?>
