txp global variables
I’ve included some self written php scripts in txp forms. What I want to do is assign txp data to my own variables., eg
$email_add = ‘<txp:linklist category=“site-email” break=”“ />’;
if I echo($email_add) it outputs the correct data but if I try and use the var $email_add in the php function mail() it doesn’t work.
I know there are $GLOBAL vars that can be used but can I also do it the way I’m currently trying to?

Two things to note:
- as long as your variables are always declared global you should be able to share them between forms
- each TXP tag has an equivalently-named function which should be called from PHP (it’s quicker than parsing it)
In your case:
$email_add = linklist(array('category' => 'site-email', 'break' => ''));The smd plugin menagerie — for when you need one more gribble of power from Textpattern. Bleeding-edge code available on GitHub.

Re: txp global variables
Thanks that will help me greatly with other stuff I’m doing too. But in this case I also need to access the <txp:link_url /> data in a similar manner. As that tag is used within a form called by linklist or within the linklist if used as a container tag then I’m guessing it’s not possible using your method(?)

Hmmm, good point. linklist sets up a global variable called $thislink, which houses info from each link in the list. I’m not sure if you can foreach() over what is returned from the linklist function (I assume not, never tried). What happens if you specify a form parameter, or provide a second argument to linklist which contains the stuff you want to pass into it (the 2nd parameter to all TXP functions is $thing, which is the contents of its container).
Failing that I guess you’ll have to parse it, which might be a tad slower (not sure) but in this case probably won’t make much difference:
$email_add = parse('<txp:linklist category="site-email" break=""><txp:link_url /></linklist>');The smd plugin menagerie — for when you need one more gribble of power from Textpattern. Bleeding-edge code available on GitHub.
