[SOLVED] Little help with .php?...

[05rmerce]

Hi,

 

Please stay with me as I am finding this quite difficult to explain

 

I would like to make a script that gets information from the database and echoes it to the page.  That I can do.  But more importantly I would like to have one file that is able to choose a different piece of information based on the URL.

 

For example, in this post window:

 

http://www.phpfreaks.com/forums/index.php?action=post;board=1.0

 

Index.php can show the index, or with the bit on the end generates the post form.

 

I would like to know how to add/use the

 

?action=post;board=1.0

 

Bit in my own scripts.

 

I hope that has come across well.

 

Thanks in advance

Use $_GET to grab that info after the ?

If you have PHP5 it's easy to build with:

http://us.php.net/manual/en/function.http-build-query.php

 

Like revraz stated, use $_GET ad in $_GET['action']. See $_GET info:

http://us.php.net/manual/en/reserved.variables.php#reserved.variables.get

 

 

FYI:

 

http://us.php.net/manual/en/function.parse-url.php

Hi,

 

Thanks very much, you were both very helpful

 

I think the parse_url will help me perfectly, thanks again.

 

Does SMF have any kind of reputation system that I can add too

Actually (and apologies for the double post).  I have just realised that I have no idea on how to get the URL of the script that the user has entered?

 

I feel stupid now 

[revraz]

Lets say this is the URL

http://www.phpfreaks.com/forums/index.php?action=post;board=1.0

 

Now on index.php you have a $_GET['action'] that has "post" in it.

 

Is that what you mean?

[05rmerce]

Not exactly

 

I would like a page to display different things based on what is after the .php?

 

For example:

 

http://server.com/index.php //Would load the main index from the database

http://server.com/index.php?view=002 //Would execute different script to load the information for record 002.

 

I think I can work it out myself, if you could be kind enough to demonstrate how I could set what the user has typed in (The URL) as a variable.

[revraz]

So it is what you mean, but you just don't realize it.

 

http://server.com/index.php?view=2

 

<?php
if ($_GET['view'] == 2) {
echo "you picked 2";
}
else {
echo "something other than 2 was picked or nothing was";
}
?>

Read up on the $_GET info. In your second example the PHP variable $_GET['view'] would contain your value of 002 (or possibly just 2).

 

If you want to assign it to another variable, simply do:

 

$view = $_GET['view'];

 

However, it's good coding practice to make sure the index "view" is there first. So, something like this is better:

 

$view = isset($_GET['view']) ? $_GET['view'] : '';

Looks perfect to me, will try and report back
