How do I post only certain fields from a form?

Copy linkTweet thisAlerts:

I’m working on a form where some fields are needed in the posted info, but depending on what they fill out, some are not. I’m not trying to hide the field from the user, just don’t want it there on the email that is sent when it posts. Been searching, but I’m not sure of the correct verbage to search for, so haven’t found it.

@gaston9x19May 05.2005 — Can you access the email script and just not have it include some fields if those certain other fields satisfy some logical condition? Seems like that would be the most direct way to customize what's sent in the email.

Test this by taking one of your fields and doing this:

<input type=text name="firstName" value="John Doe" disabled=true size=15>

Then post the form. See what happens.

@gaston9x19May 05.2005 — As Warren said, if you disable a field, it won't be posted with the rest of the form data, but you said you want it to be posted, just not emailed, right?

@Warren86May 05.2005 — If that works, in your "validation" JS code you can set disabled to true for those fields.

if (something){document.forms['myForm'].phoneNumber.disabled = true}

@Warren86May 05.2005 — And, you DON'T need to include disabled=true or disabled=false in ANY of your fields. Just use JS to disable the ones that you don't want posted, depending upon the test(s) that you conduct. If this, then these are disabled, if that, then those are disabled.

@LisaeauthorMay 05.2005 — Yes, that causes it not to post when I put it in the field. (Which is what I wanted - that it not post - sorry I wasn't clear before gaston.)

Once again, you are awesome Warren. I'm trying to hide the posts from the unused "Role" lists from the form you helped me with earlier. Haven't got the "use JS to disable" part figured out yet, but it will have to wait until tomorrow.

Thank you both and goodnight!
