Buying $10 quick (as in now) via PayPal to the first person to fix this PHP issue!!

Hi Everyone!

Ok so here is my issue, I have a small 1 field textbox form that a user will enter their code into. The PHP script below is suppose to check a plain .txt file on the server for a matching code. The text file has 10,000 random 6-7 digit alphanumeric codes in it (each one with a return break). The php code below is suppse to (and technically does) check the file to see if the number is there and send them to page A if it is and page B if it doesn't. The script works however there is one small problem - If a user enters 234 and one of the codes is A2349J it directs the user to a success page, it found the match, however it did not find the WHOLE match, just a partial. I need the script to make sure that it matches 100% and if not to go to the not found page. First user to answer this problem (via POST) for me gets $10 in their paypal account, I will user your code to check and then post results.

<?php
		// Filename
		$file = "file.txt";
		// Correct Number
		$loc_correct = "http://www.website.com/success.php";
		// Wrong Number
		$loc_wrong = "http://www.website.com/notfound.php";

			if (isset($_POST['number'])) {

				// Set Number
				$number = $_POST['number'];

				// Regezx pattern that matches exact word
				$patt = '/(?:^|[^a-zA-Z])'. preg_quote($number, '/'). '(?:$|[^a-zA-Z])/i';

				// Reads File
				$file = file_get_contents($file);
				
				// Check if $number exits in $file
				if (preg_match($patt, $file)) {
    			
    			header('Location: '.$loc_correct);
				exit;
  }
  
  header('Location: '.$loc_wrong);
  exit;
}

?>

Code (markup):

 

If so I would do the following, replace

// Regezx pattern that matches exact word
				$patt = '/(?:^|[^a-zA-Z])'. preg_quote($number, '/'). '(?:$|[^a-zA-Z])/i';

				// Reads File
				$file = file_get_contents($file);
				
				// Check if $number exits in $file
				if (preg_match($patt, $file)) {

PHP:

With

// Reads File
$file = file_get_contents($file);
$lines = explode("\r",$file);
$found = false;
foreach($lines as $line) {
	if(!$found) {
		if($line == $number) {
			$found = true;
		}
	}
}
if($found) {

PHP:

 

The codes are in this format:


A849F5
B8F9RJ
83NR856
JD7394M

They each have a return break, so 1 long list with 10,000 lines

 

Yep updated my code, misread the thread in the first place, if my code doesn't work I will need the actual file sample, as the line breaks are never the same

 

Currently your code goes to the not found page every time - even with the real code.

 

And the code below is exactly identical to the full PHP file, there is nothing else in it and line breaks and tabs have been preserved.

 

Not found? Right.. Do this then please, replace all the code with

<?php
// Filename
$file = "file.txt";
// Correct Number
$loc_correct = "http://www.website.com/success.php";
// Wrong Number
$loc_wrong = "http://www.website.com/notfound.php";

if (isset($_POST['number'])) {

// Set Number
$number = $_POST['number'];
// Reads File
$file = file_get_contents($file);
$lines = explode("\r",$file);
$found = false;
foreach($lines as $line) {
    if(!$found) {
        if($line == $number) {
            $found = true;
        }
    }
}
if($found) { 
	header('Location: '.$loc_correct);
} else {
	header('Location: '.$loc_wrong);
}
exit;

PHP:

 

Still nothing but not found

 

Did you fix the redirect URLs? I guess you edited them to not show your website.. it says website.com, not found is not because of my edits, please check

 

Of course =) Im not new to websites, I just don't write PHP code well enough to fix this. Everything I put into the form field just goes to the notfound.php page.

 

Oh thats what you mean, I thought you just meant it as it gives you 404,

Could you email me a sample of the file? to admin {at] scoding.com


I will get back to you in 5 minutes, it's something to do with the line breaks, they come in all shapes and forms sometimes

 

I just sent the file

 

I meant sample of the file with the codes, you sent me the code I posted on here

 

try this code: View attachment code.txt click and download it

its all works fine here : http://seminar.b-infotech.com

 

Scoding's snippet works fine (btw you're missing a closing bracket).

<?php
// Filename
$file = "file.txt";
// Correct Number
$loc_correct = "http://www.website.com/success.php";
// Wrong Number
$loc_wrong = "http://www.website.com/notfound.php";

if (isset($_POST['number'])) {

	// Set Number
	$number = $_POST['number'];
	// Reads File
	$file = file_get_contents($file);
	$lines = explode("\r",$file);
	$found = false;
	foreach($lines as $line) {
	    if(!$found) {
	        if($line == $number) {
	            $found = true;
	        }
	    }
	}
	if($found) { 
	    header('Location: '.$loc_correct);
	} else {
	    header('Location: '.$loc_wrong);
	}
}
?>

PHP:

 

you can check the live demo here of my code: http://seminar.b-infotech.com

if it OK for you let me know i will send the code.

 

Oh yeah forgot that I missed that(long night), anyhow if that one doesnt work, replace \r with \n depends if the txt file is put together with script or user.


Anyhow should work now

Edit: Got the sample file, it was '\n'

 

Every thing works great here, let me know have you test the below url or not????

 

BM4WEB - Just the error page, not working

SCODING - The file you sent me works just fine (I had to remove a line? "haha"?) lol please send me your paypal!

 

If you paste the below code on a php file and refresh it, then it will go every time to an not found page!

i have rewritten the stuff here: http://seminar.b-infotech.com
