page linking

[pnerd]

Hi guys. Im new here so i got much to learn.

 

Currently the sites that i make are in this format e.g. http://localhost/phpscript/test.php.

I noticed some sites have it in this format e.g. http://down.com/up/index.php?p=cs.

 

How do they get the format of "index.php?p=cs" and what does it mean?

 

Thanks.

This is said to be passing data through urls and u will get the data in te nest page.

 

URL:

index.php?name=$name

So in the next page u will get it like:

$name=$_GET['name']

well the index.php is the actual page containing the script

 

everything after the "?" is a passed variable from looking at that the page can decide what to do so for example:

 

if (isset($_GET['p']))
{
   do this
}
else
{
  or do this;
}

 

typically its to point the page in the right direction depending on what information is passed

inde.php is a file name ? this means a query idname is a variable idname=value is the value that you are passing to the page you are calling. & seperates the variables.

 

so index.php?idname1=hello&idname2=thanx    etc...

 

On the page recieving the variables you will set up your PHP to be

<php

$idname1=$_GET["idname1"];

$idname2=$_GET["idname2"];

 

echo $idname1;

echo "<br>";

echo $idname2;

?>

 

Try it out.

Thanks for the enlightenment. However, is there really a big difference between the 2 codes? If so which would be easier in terms of coding for a beginner.

it depends on what you want to do and what needs to be passed...

Do a test page and see, how it works!
