Smarty

[Galois]

Is there a smarty funnction that will append vars onto the end of a url?

I have a url that is either
index.php
or
index.php?id=12

and I want to add on
order=desc

to get either
index.php?order=desc
or
index.php?id=12&order=desc

I suspect there is a function that already exists, but I can't find it
thanks

In your php you can do as follows:
suppose you have a url in the variable $link, before appending vars insert this code:

[Galois]

no fancy smancy smarty function then, eh?

if I use this code snippet I could potentially end up with
index.php?id=12&order=desc&order=desc
the second time I run the function

this is from phplib, but still doesn't solving defining the same vars over and over again

This one works, but a bit more of a hack. It completely replaces the query string and merges $_GET with whatever you want. I'm still surprised there isn't a smarty function that does this. . . .

You'd have to make one. something like:

{$link|url_add:"foo=bar"}

and in PHP you can do it quick & dirty with a ternary operator:

As a general comment, you have to always be careful when you are considering and modifying only portion of a larger string.

For example, Mohrt's suggestion is to check for the presence of "?" in the URL -- in virtually all cases, this will work as expected, but there are some boundary cases where this is insufficient (eg. http://strange/url?itis=true/thatwill?haunt=you).

There are exisitng PHP functions to help you slice & dice urls (eg. parse_url) -- wrap what you need in a modifier, similar to Mohrt's (or use his with the understanding that it works for a vast number of possible cases).

BUT

...many people will tell you that building url strings is an application level function and should not be done in template but instead in your application.
