[SOLVED] getting section of a url

[chocopi]

Ok, So i was wondering if it would be possible to get a section of a url

 

what i mean is:

 

url = http://www.somesite.com/stuff.php?=blahblahblah

 

is there anyway i could just get the 'blahblahblah' bit

 

Thanks,

<?php

foreach($_GET as $key => $value) {

$var = $key;

}

echo $var;

?>

 

Only works if that's all there is after the URL. Won't work if you have other variables there too.

[chocopi]

well i just tested it on a blank page, but its not showing anything  :'(

[chigley]

Access the page with file.php?gdgdfg not ?=gdgdfg

[chocopi]

wow thanks it worked but a question mark appears after the test

 

for example http://www.blah.com/poo.php?hat

gives hat?

[chigley]

That's what you want it to do isn't it?

[chocopi]

well i would like so it says 'hat' instead of 'hat?'

[chigley]

It shouldn't do, works fine for me? :S

[chocopi]

strange

 

so when i click on 'cheers.php?mark' it gives me 'mark?'

 

is there anything wrong with what i did

[chigley]

Access the page in the same way (file.php?var) but change the file to this:

 

<?php

echo "<pre>";
print_r($_GET);
echo "</pre>";

?>

 

And paste the output here.

[chocopi]

that gives me

 

Array
(
    [mark?] => 
)

[chigley]

Weird...

 

<?php

function urlpart() {

foreach($_GET as $key => $value) {

  $var = $key;

}

$length = strlen($var);
$length = $length - 1;
$var = substr($var, 0, $length);

return $var;

}

echo urlpart();

?>

[chocopi]

wow thanks it WORKS WHOOP. CHEERS

 

could it do with the fact that im using lycos to host it ?

[chigley]

Not sure what it is, it works on all my servers normally, but you have a function now for your server specifically

[chocopi]

is there any way i can set this urlpart(); to a variable ?

[chigley]

<?php

$var = urlpart();

?>

[chocopi]

thats what i thought.

 

could you please try and sort this:

 

<?

require_once ('page_header.php');

require_once ('url.php');

$code = urlpart();

$query = "SELECT active FROM users WHERE code = '$code'";

$update = "UPDATE users SET active ='1' WHERE code = '$code'";
mysql_query($update) or die (mysql_error());

print ("<br /> \n");
print ("<center> \n");
print ("$username, your account is now active, please login on the homepage. \n");
print ("<br /> \n");
print ("<br /> \n");
print ("<a href=\"index.php\">Home Page</a> \n");
print ("</center> \n");

?>

 

url.php is where the code you gave me earlier and page_header.php is the database connection.

 

so what this is meant to do is just update the active field from 0 to 1 using the code you gave me to get the activation code

 

thanks,

[chigley]

How does it know the $username value?

[chocopi]

yea thats the sort of problem i need help with,

 

its meant to be taken from the same row as the activation code

[chigley]

<?php

require_once ('page_header.php');

require_once ('url.php');

$inputcode = urlpart();

$query = "SELECT * FROM users WHERE code = '$inputcode'";
$result = mysql_query($query) or die(mysql_error());
$result = mysql_fetch_assoc($result);

$realcode = $result['code'];
$username = $result['username'];

$update = "UPDATE users SET active ='1' WHERE username = '$username'";
mysql_query($update) or die (mysql_error());

print ("<br /> \n");
print ("<center> \n");
print ("$username, your account is now active, please login on the homepage. \n");
print ("<br /> \n");
print ("<br /> \n");
print ("<a href=\"index.php\">Home Page</a> \n");
print ("</center> \n");

?>

Try that

[chocopi]

wow thanks it worked.

 

just out of intrest how did you learn all of this php ?

[chigley]

Practice. Just think up interesting project ideas and don't give up until you get it how you like it

[chocopi]

well thanks and all the best
