Bind checkbox to file name column when deleting file

I have an update form with 3 images. I need to add checkboxes next to each image so that when checked, will delete those images on update.
This is working fine and the image is deleted. But the file name remains in the column.

What I have so far;
-Update behavior for the database. Triggered by the Update button being pressed.
-Upload file behaviors (one for each file field). Default is server filename.
-Delete file behaviors (one for each file field), triggered if it's checkbox is checked.

What I am trying to figure out is how to tell the update behavior that if the checkbox is checked, to clear that column only.

I tried going with the thread #19034. But the client really wants checkboxes so they can update the other fields and delete an image at the same time.

Any help would be appreciated.

Thanks,

send a copy of your page, so i can see the code, and i can tell you what to change.

Thanks Jason, Here you go.

change line 55 and 65:

'DefaultFileName' => "".((isset($_POST["imagename"]))?$_POST["imagename"]:"")  ."",

to:

'DefaultFileName' => "".((($_POST["deleteimage1"] != "delete"))?$_POST["imagename"]:"")  ."",

change line 79 and 89:

'DefaultFileName' => "".((isset($_POST["imagename2"]))?$_POST["imagename2"]:"")  ."",

to:

'DefaultFileName' => "".((($_POST["deleteimage2"] != "delete"))?$_POST["imagename2"]:"")  ."",

and change line 103 and 113:

'DefaultFileName' => "".((isset($_POST["imagename3"]))?$_POST["imagename3"]:"")  ."",

to:

'DefaultFileName' => "".((($_POST["deleteimage3"] != "delete"))?$_POST["imagename3"]:"")  ."",

Wow Jason, as always thanks so much. That worked perfectly.

Just for my own study and understanding. What you did there was tweak the file Upload behavior to use the default name as before but only if the checkbox did not post the value of "delete"? And if it did post the value of "delete" to use a blank value as the default?
Is that correct?

I just wanted to make some notes. But either way, thanks.

Yes Troy, that's spot on.

the code is using a ternary condition to use the regular default image if the delete checkbox does not pass the value "delete" and a blank string if it does.
