Pass "?pg=X" into txp_article... manually?

Is it possible, or… How possible would it be to manually pass the “?pg” query string variable into <txp_article />?

Bascially, I would like to setup a script where the article will still output an article list if someone manually changes the “?pg” GET variable to a page number that does not exist…

For example, lets say I only have two paginated pages… and someone inputs “?pg=3” into the URL… That would return nothing via the <txt_artlicle /> tag… I would want to check if the return value of <txp_article /> is “”, and then itterate to the nearest page number that returns articles.

How possible does that sound?

Lol, am I making sense here? :D

TIA!
Cheers,
Micky

Re: Pass "?pg=X" into txp_article... manually?

What are you asking? That, if $thispage['pg'] is bigger than $thispage['numPages'], then $thispage['numPages'] will be outputted?

Because I don’t actually get what you mean, if you want make input field for changing pg, that just create field named to pg.

Cheers!

Not tested but you could put to top of your page something like:

<txp:php>
global $thispage;
if($thispage['pg'] < $thispage['numPages']) {
	$path = site_url().section().'/?pg='.$thispage['numPages'];
	header("HTTP/1.x 301 Moved Permanently");
	header("Status: 301");
	header("Location: ".$path);
	header("Connection: close");
}
</txp:php>

Remember, not tested at all.

Cheers!

Hi Gocom! Thanks for the reply. :)

Yah, that sounds good to me… You gave me some good ideas. Thanks for the tips.

Sorry if I did not explain well. Basically, I want to have <txp:article /> return an article list, even if the URL query string is manually changed to be a page number that does not exist… Kinda hard to explain.

I am thinking about writing a function that will check for this, and alter $_GET['pg'] by calling itself if <txp:article /> returns FALSE. But, now that you mention $thispage['numPages'], I may use that to error-check against.

Thanks again for the tips! Sometimes I need the pro’s to get me going in the right direction. :D

Cheers,
Micky
