Image Global error...

Weird. I'm trying to get the following global to work with an upload field;

Code:
sub {  
  my ($ID,$Field) = @_;  
  my $file = $DB->table('Links')->file_info($Field, $ID);  
  return $file->File_URL();  
}

Its called with;

Code:
<%if ImageURL($ID,Image)%>

When I do this, I get an error:

Quote:

Can't call method "File_URL" on an undefined value at (eval 22) line 5.

If I add the following code in (after the 'shift' call);

Code:
return "ID: $ID, Field: $Field";

...I get;

Quote:

ID: 118, Field: Image

Anyone got any ideas why I'm having this problem? Unsure

Cheers

I just tried it on my site and it works.

Try putting Image in quotes? Do you definitely have a field called Image in the Links table? Tongue

Sorry - I see that I wasn't paying enough attention Blush

I called it with <%ImageURL($ID,Image)%> which worked. I've just tried it again with <%if ImageURL($ID,Image)%> and got the same error as you. I have no idea why this causes a problem.

However, I think you can get round this with <%set Imageurl=ImageURL($ID,Image)%> and then use <%if Imageurl%>

What I ended up doing, was something like;

<%if Image1%>
<img src="<%ImageURL($ID,Image1)%>">
<%endif%>

That seemed to work fine Smile
