How to include data from a php file without include function-CodePudding

I am working on a signup page in html and PHP. When all is correct, it should redirect you to another file. I have two files, one is techer.php the other indexa.php. I want redirect from techer.php to indexa.php and then include techer.php to get some data from it. I thought the way to go about this was include("techer.php") but when I do that, I would get stuck in a redirect loop and then it will say: localhost redirected u too many times.

This is techer.php:

<?php
$servername = "loc";
$username = "$$$$$$";
$password = "$$$$";
$dbname = "demoq";


$name = $_GET['username'];
$skool = $_GET['skool'];
$email = $_GET['email'];
$pwd = $_GET['password'];

$hashed = password_hash("$pwd", PASSWORD_DEFAULT);
mkdir($skool, 0700);
$myfile = fopen("$skool/index.html", "w");
$myfile1 = fopen("$skool/index.css", "w");
$myfile2 = fopen("$skool/submit.php", "w");
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO `teacher` (`School`, `Email Address`, `Password`, `Username`)
VALUES ('$skool', '$email', '$hashed', '$name')";

if ($conn->query($sql) === TRUE) {
  echo "New record created successfully";
} else {
  echo "Error: " . $sql . "<br>" . $conn->error;
}

echo file_put_contents("eacher.html","Hello World. Testing!");

$conn->close();
header("Location: /school/choose/indexa.php");
exit();
?>

and then, of course, the is indexa.php:

CodePudding user response：

It seems to me the solution to your immediate problem is very simple: create a third file.

You have some code in "techer.php" which you want to run again in "indexa.php", and some which you don't. So move the code you want to run in both to a new file, say "getdata.php", and then include that from both places.

I would also encourage you to find a tutorial that teaches you how to structure your code into functions and classes. Then, rather than just using include to run exactly the same code in more than one place, you can write a function with parameters to perform similar code in more than one place.

CodePudding user response：

Others have already pointed out some security concerns so skipping that.

You can combine the two files and wrap the code from teacher.php in a conditional like

if (!empty($_POST)) {
 // teacher.php code here
}

and remove

header("Location: /school/choose/indexa.php");
exit();

Then you can use the values of the POST variable for use on that page with $_POST. Reference https://www.php.net/manual/en/reserved.variables.post.php

Hope that helps, do consider the comments people made about security.
