Ok, I'm pretty new @ PHP and still trying to figure out how CCS handles it.
I have a "Label" (content is a database column) which I'll like to hide if
another column has the value "No".
I added a Hide-Show Component to the Before Row Show. I selected
"Expression" but nothing that I have tried works.
The Label is called "Title", the field that will decide if to display is
"DisplayTitle". The form is called "content"
I have tried several options and I keep getting this error: Fatal error:
Call to a member function Show() on a non-object in
C:\Inetpub\wwwroot\Caracol\index2.php on line 169
Any help will be great ....

Put Pannel around your Label (which you want to hide), set it to visible.
Don't use Hide-Show Component with the Before Row Show event - it will not works well because produces non complete code like:
if ($Component->DisplayTitle->GetValue()=="something")
$Component->PanelTitle->Visible = false;
that is not covers all cases.
instead use just Custom code like:
if ($Component->DisplayTitle->GetValue()=="something") {
$Component->PanelTitle->Visible = false;
}else{
$Component->PanelTitle->Visible = true;
}

Gena ... many thanks ... got it working.
1 more question, if the field I want to evaluate is not in a control but it
is part of the query ... how would I substitude if
($Component->t_linkh->GetValue()=="")? Would I have to use CCDLookUp?
(seems inefficient).

Just put that field as Hidden box somewhere in grid row and then use it as described above.

of course you can use CCDLookUp but this will slow down your grid...

LOL ... that is what I was doing but there should be a better way ... glad
to know that as a PHP novice ... I was not that far off (although this is a
CCS issue).
Thanks.

The better way is really depends of what you need to do. If you can add than field in the query and then put it as hidden box - this is fast and easy.
If you need to do some complex check you can use lookup function or ever create your own check function.

-------------------------
If it's part of your query or dataset, then you should be able to get to
it via:
$Container->ds->f("YourField");
