Currently I have the following in my results page.
<td width=86>
<a href="[area [item-code]]">
[if-item-field thumb]
<img border="0" src="thumb/[item-field thumb]">
[else]
<img border="0" src="thumb/80.gif">
[/else]
[/if-item-field]
</a>
</td>
My question is how would you do "If file exists" instead of the above
if-field exists? In other words, I want to test if the image file
exists, and if so display the image. If not, display the default image.
The other question with this is if I can do a "if file exists" clause,
how resource intensive is that. If people feel that this would be too
slow, what other solutions do people know of. (The only other one I can
think of is to setup a crontab entry to update specific fields in the
database nightly, according to the contents of specific directories.)
Thank you,
