Hi,

I want to simply add the name of the logged in user to one of my new pages.

Is it acceptable to add {$USERNAME} to the COMCODE page ?

I have done this and it works.

But should this really be on a template ?
But then how does the template get invoked for your page ?

Can I use all the TEMPCODE directives on my COMCODE pages ?

I think that I am confusing myself here - can anyone put me straight please !!

Cheers,
Ade

Yeah it works fine :).

Comcode pages:
Comcode & Tempcode –> Compiled Tempcode

Templates:
Tempcode –> Compiled Tempcode

Many Comcode tags are driven by templates, it all gets mixed together into that final compiled Tempcode, which is what ocPortal caches in the database.

Cheers Chris

Looking through the tempcode I see that it is a string only language.

Say for example I wanted to use the $LT to compare two numbers:

Looking at the help guide it says:
"Test for numerical less-than inequality (pass in a Tempcode number)"

What is a "Tempcode number" ?

In other words, there are no data types. It is all text, and things like LT will just interpret that text as a number, assuming that it contains one.

I guess I asked for that - but thanks for the clarification !

I was trying out some comparisons to get some familiarisation and they did not appear to work - but it was just a typo of mine !

Chris how would it deal with a real string then? I mean if someone sent the LT an actrual string that is not parsed as a number would it compare string lengths then or just fail? ie: is Bob < Fred?

It'd do whatever PHP's intval does in most cases. Likely Bob and Fred would both be treated as zero.
