Hello,
I am experiencing some problems in getting the conditional statements in the image display to work.
Your existing code is:
Which I understand to mean: If there is a thumbnail use it and if there isn't use that image instead. However if there is neither a thumbnail nor image then download the file.
I've substituted the last line to display a generic image but that line is not being executed and that is my query. Why isn't it being executed.

Hi Terry,
in it's current form your last line is a link to the same image that's referred to in the preceding 'isimage' statement.
If you want to display a generic image you should use something like this:
Plus any styling (centering, borders, etc) that you want to include.

Hi Jerry,
Been there, done that, don't work! That's why I posted this question because I figured that it should work.
I've settled for wrapping the whole code block in a PHP conditional statement as follows:

Hi Terry,
Sorry, uploads are a little funny.
Here's another approach that I found on the forum:
But whatever works is the one to use.

Hi Terry,
Your approach should definitely work. I noticed you're referencing $upload['tab_image_generic'], but you probably want to use $record['tab_image_generic'] instead:
This assumes that your tab_image_generic field is a textfield which contains a URL (either relative or including http://). Is that correct?
Please let me know if you have any questions.

Hi Chris,
I tried both what you suggested in the previous message (which I really thought would have worked) and the following and neither worked.
Unless you can spot something obvious then I am happy to leave this at this point as I have already wrapped the entire thing into a PHP conditional statement which is working.
Regards
Terry
