page.php?section=a&id=2 ?????

mycro

I'm wondering where "section" "a" "id" and "2" come from. Is there some tutorial out there that can explain these to me? I don't understand. Thanks

everything up to ? is the web page address
after the ? sign you have parameters
in this case you have
$section = "a"
$id = 2

I realize that, but how are they defined?

This is a difficult question to answer because we have no idea where it's defined. Odds are there is a database that keeps track of sections and ids. So one has a script that generates links to all sections and a user clicks on one, then a script shows all ids for that section and a user clicks on one and then I guess this views the contents of data for that section and id.

But anyway, maybe this will help:

You could create a link and define the variables right there

That would be the same as doing

$var1 = "4";
$var2 = "9";

Except by doing this, the variables will be passed on with those values to newpage.php

If you have $var1 already defined, and just want to pass that value on to newpage.php

When mentioning passing external variables it's important these days to assume register_globals = off. See:

page.php?section=a&id=2 ?????

page.php has some code that take variables(from url) section and id. Try page.php?section=fefwef&id=90000 what happened

I guess section and id is refernce variable..(page.php?section=$value&id=$value)

ok.. I m just writing quick notes that might give u some idea

let say I got a table call employee

as follow

emp_id|emp_name|emp_location|emp_desc

data are :

1|John|4|Expert
2|netmastan|6|still beginer

Now let say we want to findout employee details by emp_id and emp_location.

We write a function in index.php that will display employee details just by emp_id and emp_location.
(ie.index.php?action=empdetials&emp_id=1&emp_location=6)

Here is function


function empdetials($emp_id,$emp_location) {

$result=mysql_query("Select emp_id,emp_name,em_location,em_desc where emp_id=$emp_id AND emp_location=$emp_location",$dbi);
//$dbi is datbase connection

list($emp_id,$emp_name,emp_location,emp_desc)=msyql_fetch_array($result);

echo "#$empd_id.Employee Name :$emp_name .Employee locaton :$emp_location<br> Description:$desc";

}


switch($action) {

case "empdetials":
empdetials($emp_id,$emp_locatoin);
break;

}

So, I can use now . index.php?acton=empdetials&emp_id=$emp_id&emp_location=$emp_location
(ie.index.php?acton=empdetials&emp_id=1&emp_location=6)
