How to Get the Value of field_code_file

Question

Considering that I know the NID of the node, how can I get the value of one of the field that belongs to that NID?

I tried everything I can to get the value of field_code_file with the following code:

$node = node_load($_GET['nid']);
$wrapper = entity_metadata_wrapper('node', $node);
$file = $wrapper->field_code_file->value();

The value returned by $file is "array". Here's the value:

Array ( [#theme] => field [#weight] => 0 [#title] => Code File [#access] => 1 [#label_display] => above [#view_mode] => _custom_display [#language] => und [#field_name] => field_code_file [#field_type] => file [#field_translatable] => 0 [#entity_type] => node [#bundle] => source_code [#object] => stdClass Object ( [vid] => 71 [uid] => 1 [title] => Billing Software [log] => You can now download the installer for Billing System.

I am expecting a value like this:

http://www.mysite.com/sites/default/files/download/admin/Billing%20System.zip

I'm using this code in my simple module that I created.

For Jeet:

Thanks. When I use this command print_r($file), it returns this value:

Array ( [0] => Array ( [fid] => 37 [display] => 1 [description] => [uid] => 1 [filename] => Billing System.zip [uri] => public://download/admin/Billing System.zip [filemime] => application/zip [filesize] => 864517 [status] => 1 [timestamp] => 1227589659 ) )

Now how can I get the full url like:

http://www.mysite.com/sites/default/files/download/admin/Billing%20System.zip

I'm trying to understand what you mean by file_create_url($uri), but I can't crack my head on it.

Can you please explain it to me further?

Thank you

Answer 1

Assuming the field is a file type.

$node = node_load($_GET['nid']);
$file = field_get_items('node', $node, 'field_code_file');

Print the $file. you will get a URI index. To get your full path to file use function file_create_url($uri)

Let me know if this doesn't get you the result.
