I'm wanting to do a conditional rewrite with differing numbers of parameters some optional.

Is this possible

this would need to go into index.php as

The page value is optional

I can't think of an easy way but this is way into RegEx not so much htaccess.

You would need your index to use a switch statement on the function element, I expect from there the htaccess wouldn't be too hard.

I'll have another look after I get back home, I'm about to head out in 30 minutes or so.

If your familiar with basic rewrites once you break up the function switches the rest should be simple.

I'm interested too

Basically a way to pass 'x' parameters based on number of 'x' folders

Looked into this previously but couldn't find an answer

I ended up having to hardcode all alternative number of parameters

/1/2/3/ -> page.php?parameter1=1&parameter2=2&parameter3=3
/1/2/ -> page.php?parameter1=1&parameter2=2
/1/ -> page.php?parameter1=1

I'll have a look this as would be really useful

Maybe something like

RewriteRule ^/(.*)/?(.*)/town/?(.*) index.php?function=$1&category=$2&town=$3

I haven't checked this but it may give you a starting point.

Would need to pass a blank variable for optionals like page= then use the PHP to disregard the option, with an if $_post['page'] == "" then $page=0 kinda deal.

Nick, yours is easy

RewriteEngine on
RewriteRule ^(.*)/(.*)/(.*) sample.php?var1=$1&var2=$2&var3=$3

That will call the sample.php document and populate var1-3 with the folder names.

Try it with

<?php
echo "1 = " . $_GET['var1'] . "<br>";
echo "2 = " . $_GET['var2'] . "<br>";
echo "3 = " . $_GET['var3'] . "<br>";
?>

in the sample.php file.

The other one is complex due to not using the same function, you could write mod_rw for each function but it would be a killer regex to do it in one go.

Thanks for the replies

Using

RewriteEngine on
RewriteRule ^(.*)/(.*)/(.*) sample.php?var1=$1&var2=$2&var3=$3

could this cope with variable number of parameters or would I need a rule for each number of parameters? Handling in the PHP code is quite simple as the function would define the number of parameters I'm expecting and my code alread reads the input and sanitises it before assigning to local variable / SQL query string.

I guess as long as your URLs was contructed the same way everytime...

You would just need to sort it out in php.

You would need to pass it ALL the possible variables, so if there was 7 possibles you would need to pass it all 7 every time, then use php to test the content of the variable.

Because, Town, Country, Search, Show all seem to be static variables, you could write 1 rule for each 'type' and simply check for the type.

case 'search':
$var1 = blah
etc

case 'show':
etc

Then you could disregard the exess fragments there.

The important bit is that your URL structure never changes otherwise the variables would too.

I was thinking more of the regex rather than the PHP, I'll know from function what expect, but the URL will have differing number of parameters and my limited regex knowledge would suggest that sample above is working with just 3 parameters and would fail if just 2.

I guess I'll need to devote an hour or so to "fiddle time" and see what I can make it do.
