i have a link label that links to uploaded pictures the pathto the picture is stored in a field named picture
the link is in a field called vendor_proof_number
so i have a list of hyperlinked vendor_proof_numbers only problem is not every record has a picture that has been uploaded yet
so i would like to kill the hyperlink on records were there is no picture so users don't go down a dead end
if $form->picture->getvalue()!=null
drop the <a href images/{picture}
i'm confused as to where to write code i have added "images/" directory to the picture path in HTML
thanks
DD

have you tried this:
If there is no picture then the flename of the picture will probably be
empty.
Test for empty filename and replace it with a '#'
The hash will point nowhere and the link will go nowhere.
You could (MySQL) do this with an ifnull() around your photoname.
Just a quick response.

You can put your code in the grid's BeforeShowRow event.
if (!$Container->picture->GetValue()) {
$Container->vendor_proof_number_Link->Visible = false;
}
Make sure that your vendor proof number link's visibility property is
set to Dynamic.

------------------------------
Additional note on this:
If you're not actually displaying the field "picture" in your grid, then
you'll not be able to check it's value using the GetValue() function.
You'll have to check for it's value via:
if ($!Container->ds->f("picture")) {

that works and it removes the Vendor_proof_Number. i use the vendor P number to link when a file has been uploaded to show that file
I want to neuter the hyperlink when there is no file and stop the user from getting an error page not found type thing
maybe i need to go at it the other way and make the field a plain label and add a hyperlink where there is a file to link to
after pulling hair i'll have to settle with this for now
global $YProofing;
if ($YProofing->picture->GetValue()=="")
{
$YProofining->Vendor_Proof_Number->SetValue("no_file ".$YProofing->Vendor_Proof_Number->GetValue());
} // <a href="images/{Vendor_Proof_Number_Src}" target="_blank">{Vendor_Proof_Number}</a>
// -------------------------
//End Custom Code
this adds " no_file" to the Vendor # i.e.
Vendor_Proof_Number
no_file 000008
but it's still a hyperlink that leads to a dead end /images i guess i could make a page that redirects back
this part is in my HTML
<a href="images/{Vendor_Proof_Number_Src}" target="_blank">{Vendor_Proof_Number}</a>

I just realized that i don't have a beforeshowrow event on the grid i guess because it's report grid ?
i was going to just add the picture field and use that link instead of vendor_proof_number making my printing issue harder to fix
