field validation before displaying HTML

[ctaylor]

Is there anyway to test a field in a database for contents before displaying some HTML code? Example: I am trying to test to see if there is an image in one of my fields before I put a link to that image. Some of my records will have images and others won't and I don't want some of my records to have bad links. I tried doing a boolean test on the field hoping that filemaker would return a true if an image was there and a false if not. That didn't work. I would appreciate any idea. Thanks in advance.

The way I do it (which is probably long winded) is to make the field that states the route to the picture have an auto entry of "none" and then put on the page [fmp-if: picturelink.eq.none][fmp-else]<img src="http://www.mydomain.com/pictures/[fmp-field: picturelink]">[/fmp-if]

This shows the picture if you have added a link, and no picture if you haven't.

If you are having the picture in a container field, then I don't know haven't had to think about it, as I found having pictures served this way to the web from filemaker was very slow.

Hope this helps

Simon is right regarding the use of the [FMP-If] statement. My only improvement is not to use an autoentered field, instead use a calculation field with the IsEmpty function in it, then check to see whether the calc field is "1" if no image, or "0" an image is present.

[FMP-if: picture.neq.] FM image here [FMP-Else]Picture not in databaze.[/FMP-if]

always worked for me.
