another question about not showing unused defined fields
|

I saw the solution about what to do if a field doesn't have anything in it and you don't want it to show up, use a little script. Sorry to sound ignorant here but that script
<script language="Javascript">
if ('$art_field#$' != '') {
document.write("Field name: " + '$art_field#_he$');
}
</script> where exactly do I insert it? in the head? And do I have to put in each field I want that to apply to? Please say no

Hey Erin,
I'm afraid so... this little script examines only ONE field to see if it's blank, so you'll need to include it for all fields that you think might be occasionally be empty. Concerning the placement of the code, you have to find the location of where the fieldname is being printed to the page, e.g.
Field name: $lfield55$
and replace that entire thing with the javascript code. Also, be sure to add the noscript tags, after the closing script tag:
<noscript>
Field name: $lfield#$
</noscript>
This is printed to the screen if the user's browser isn't javascript enabled. Without this, anyone non running javascript wouldn't see anything for that field - even if it has a value!
[Oh, and also you'll have to change the art_field to lfield, for Realty Manager instead. :-) ]

Benjamin, I have no hair left, I've pulled it all out! Ok here is the problem, I'm using the code below to hide fields like you told me:
<br>
<font face="ms sans serif" size=3><b>$lfield2$
<script language="Javascript">
if ('$lfield3$' != '') {
document.write("ARI#: " + '$lfield3_he$');
}
</script></b></font><br>
Field number 2 is male or female, field number 3 has the title of ARI# and if there is one, obviously there would be one. What I'm getting back is this: ARI#: Female <<that is what is coming out on the page.
Here is the url if you want to peek.

Hi Erin,
Thanks for the link.
Well, first of all your code WILL print out the value of $lfield2$ first, so what's it's value in that particular page?
I must admit, the javascript looks fine... try playing around with the value of lfield3 for that listing (removing it entirely, changing it's value), and refresh the page each time. Is there any correlation between the output and that field's value?

Hi Benjamin, for whatever reason the javascript is working great-thank you! Do you know if there is a way to have it fill in or not depending on if it's filled out when the Field Name is one <td>and the fill in is the other <td>? I can't figure out how to get columns to line up unless I have to seperate cells for title and answer. Just asking, not a major thing......unless my client says it is.

Sure! You could just change this:
if ('$lfield3$' != '') {
document.write("ARI#: " + '$lfield3_he$');
}
to this:
if ('$lfield3$' != '') {
document.write("<td>ARI#:</td><td>" + '$lfield3_he$' + </td>);
}
And that should just about do it... to be honest, it'd rather tricky to know exactly how you want it without looking at your page code. But the above will certainly place the fieldname and field values in two different cells.
Hope this helps! :-)

Could you check this one more time for accuracy:
if ('$lfield3$' != '') {
document.write("<td>ARI#:</td><td>" + '$lfield3_he$' + </td>);
}
Is that second <td> in the right place? Something isn't right, the field isn't showing up now whether there is something in it or not. I'm going nuts here because it's time to implement all this stuff we've talked about html, hidden blank fields and neither is working! I must be doing something wrong here. Here is the url http://design.criabarn.com/rm/listings/ pick the first one, this one I know has a birth date but the field and date are not there, if you reveal source you will see my coding and it shows up in the coding as having a birthdate and the actual date shows in the source but not on the page itself.

Good news I was playing around with the coding because something did seem right with the quotation mark so I changed it to this:
<script language="Javascript">
if ('$lfield6$' != '') {
document.write("<td>BIRTH DATE:</td><td> + '$lfield6_he$' + </td>");
}
</script>
I got it to show the fields but still ended up with a problem, here is what is showing up now:
BIRTH DATE: + '6/8/01' +
So there is a problem with the second <td> any ideas??

The quotes and the +'s were still mismatched. Try this simpler version:
<script language="Javascript">
if ('$lfield6_je$' != '') {
document.write('<td>BIRTH DATE:</td><td>$lfield6_je$</td>');
}
</script>
The quotes have been changed to single-quotes only, and _je added to the fieldname to ensure that any embedded single quotes in the value won't mess up the script.

That will work too if you're dealing with date data.
