Geting a value from a website

[jackyyll]

i need to get a few values from a website... (the values i need are in red)

  <input type="hidden" name="codeid" value="[color=red]06d9b659a29457953665eb06f767376b[/color]">

<input type="image" src="secImage2.php?rand=185&codeid=06d9b659a29457953665eb06f767376b" name="secCode">

(the values are always changing though...)

I'm not 100% sure what you are asking but I'll guess.

Are you asking how to retrieve the values of the parameters to which the values highlighted in red in your code sample are associated to?

If that is what you mean click on this link http://us2.php.net/manual/en/tutorial.forms.php

$html = file_get_contents('http://site.com/form.php');
preg_match('/name="codeid" value="(\d{32})"/i', $html, $codeid);
preg_match('/src="secImage\.php\?rand=(\d+)/i', $html, $random);

$code = $codeid[1];
$rand = $random[1];

something along those lines will capture what you want from the form.

[jackyyll]

 $html = file_get_contents('http://site.com/form.php');
preg_match('/name="codeid" value="(\d{32})"/i', $html, $codeid);
preg_match('/src="secImage\.php\?rand=(\d+)/i', $html, $random);

$code = $codeid[1];
$rand = $random[1]; 

I tried that and it wont work still :/ when i do

<? echo $code ?>

its not there. Like when i do veiw source the place where they should be is blank :/

[drew010]

ah my bad, change that first line to
preg_match('/name="codeid" value="([\da-f]{32})"/i', $html, $codeid);

[jackyyll]

Still doesnt work 🙁 This is what i have:

<?
 $html = file_get_contents('http://fabar.outwar.com/attack.php');
preg_match('/name="codeid" value="([\da-f]{32})"/i', $html, $codeid);
preg_match('/src="secImage\.php\?rand=(\d+)/i', $html, $random);

$code = $codeid[1];
$rand = $random[1];  

?>

Then i just do

<? echo $code ?>

right?

i looked at the page, i see now with the url, that you have to be logged in to view the actual page. thats why the codes arent showing up. file_get_contents wont work in that case. you will need to use [man]curl[/man] to login and manage cookies, or use [man]fsockopen[/man] to make the requests and handle the cookies yourself.
at that point you should be able to get the correct page and have the code above work.

[jackyyll]

Well im loged into it in another window so it has the cookies already... why wouldnt it work?

[drew010]

for one file_get_contents doesnt handle any cookies in the first place, so you will need to use a library that does or handle them yourself. being logged in in another window wont help because php wouldnt know the cookies exist or even where to get them, thats why you have to handle them yourself, like the browser does for you.

[jackyyll]

How would i go about doing that? lol

[drew010]

curl is the easiest way to deal with cookies. they have a lot of basic examples on the various pages, read through there, you should be able to figure it out with after trying a few examples.

[jackyyll]

Its not so easy for me :/ Well ill just give up then. Or find someone who knows how to get those values, becuase i know some people know O.o
