So I'm trying to make a program that makes it so that you input whether it's a hardback or paperback book and it outputs if it's found or not found and how many books are in stock based on the 2 txt files i have. I can get it to display the Not Found part, but the problem is is that it does it for every book. My code:

 

 

<form method="post" action="">
    <p>Name: <input type="text" name="book" value="<? echo $_POST['book'];?>" ></p>
    <p>Hardback or Paperback (enter h or p): <input type="text" name="hp" value=<? echo $_POST['hp'];?> ></p>
<p><input type="submit" name="submit" value="Reorder" /></p>
<?

if( isset($_POST['submit'])){
$book = $_POST['book'];
$hp = $_POST['hp'];
$paperback = array();
$hardback = array();

$file = fopen("paperback.txt", "r") or exit("Unable to open file!");

while(!feof($file))

  {

  $f = fgets($file);

  array_push($paperback, $f);

  }

fclose($file);

$file2 = fopen("hardback.txt", "r") or exit("Unable to open file!");

while(!feof($file2))

  {

  $g = fgets($file2);

  array_push($hardback, $g);

  }

fclose($file2);
//print_r($paperback);
$implode = implode('",',$paperback);
$explode = explode('",',$implode);
$numbers = array();
$paper_titles = array();
//print_r($explode);
for($i = 1; $i <= 9; $i = $i + 2){
array_push($numbers,$explode[$i]);
}
//print_r($numbers);
for($i = 0; $i <= 8; $i = $i + 2){
array_push($paper_titles,$explode[$i]);
}

//print_r($paper_titles);
sort($paper_titles);
$first = 0;
$last = 4;
$flag = false;
if($hp == "p"){
	while($first <= $last && $flag == false){
		$middle = intval(($first + $last) / 2);
			if($book == $paper_titles[$middle]){
				$flag = true;
			}
			elseif($paper_titles[$middle] > $book){
				$last = $middle - 1;
			}
			elseif($paper_titles[$middle] < $book){
				$first = $middle + 1;
			}

	}

	if($flag == true){
		echo "Found, and there are " . $numbers[$middle] . " copies in stock.";
	}
	elseif($flag == false){
		echo "Not found";
	}


}
$implode_2 = implode('",',$hardback);
$explode_2 = explode('",',$implode_2);
$numbers_2 = array();
$hard_titles = array();
//print_r($explode);
for($i = 1; $i <= 9; $i = $i + 2){
array_push($numbers_2,$explode_2[$i]);
}
//print_r($numbers);
for($i = 0; $i <= 8; $i = $i + 2){
array_push($hard_titles,$explode_2[$i]);
}

//print_r($hard_titles);
sort($hard_titles);
$first_2 = 0;
$last_2 = 3;
$flag_2 = false;
if($hp == "h"){
	while($first_2 <= $last_2 && $flag_2 == false){
		$middle_2 = intval(($first_2 + $last_2) / 2);
			if($book == $hard_titles[$middle_2]){
				$flag_2 = true;
			}
			elseif($hard_titles[$middle_2] > $book){
				$last_2 = $middle_2 - 1;
			}
			elseif($hard_titles[$middle_2] < $book){
				$first_2 = $middle_2 + 1;
			}

	}

	if($flag_2 == true){
		echo "Found, and there are " . $numbers_2[2] . " copies in stock.";
	}
	elseif($flag_2 == false){
		echo "Not found";
	}


}
}

Anyone? :/ :/

I really need help.

[Drippingblood123]

AlexWD do you know what to do? You've given some pretty good help before.

Please Read RULE #17!

What's the format that data is stored in the two files? Can you post an example?

 

I'd also suggest you use a select input for hardback/paperback instead of having them enter h or p, it's much more user-friendly.
