[support] Calling a field in a node template - need PHP help

[andrea burton]

@David Metzler

Thank you!! your solution worked but with modification.

This caused an error:
> if ($node->$node->field_file[0]['filepath']) print l(t('Download
> Article'), file_create_url($node->field_file[0]['filepath']));

recoverable fatal error: Object of class stdClass could not be  
converted to string

but i removed the first $node-> to have this:

> if ($node->field_file[0]['filepath']) print l(t('Download
> Article'), file_create_url($node->field_file[0]['filepath']));

and it worked! thank you, im still learning PHP syntax and didnt know  
how to do a simple if else statement like this.

@Francisco, the reason i didn't go with standard drupal behavior is  
because i didn't want the title of the node to be the link text. That  
is how it was showing up in my configuration when i selected Generic  
Files. If there is a way to take take the Label and make it a link to  
the file in the CCK manage fields admin dialog, i would love to learn  
about it.

thanks so much for everyone's help.
