Password

[layan]

Hi all,
I wrote this code. it’s working but I want to add some conditions such as passwords to be a minimum of 8 characters,A password must contain at least one digit, at least one uppercase letter, and at least one lowercase letter. Anyone can help me.

[php]// Check for a password and match against the confirmed password:
if (!empty($_POST[‘pass1’])) {
if ($_POST[‘pass1’] != $_POST[‘pass2’]) {
$errors[] = ‘Your password did not match the confirmed password.’;
} else {
$p = mysqli_real_escape_string($dbc, trim($_POST[‘pass1’]));
}
} else {
$errors[] = ‘You forgot to enter your password.’;
}
[/php]

What have you tried?

Here’s a simplified version of a validation function that I use:
[php]<?php
$errors = [‘validPassword’ => true, ‘matchPassword’ => true]; // Set all errors parameters initially to true:

/*

• Passing password and verify passord to function, plus
• passing errors array by reference.
  /
  function passwordCheck($password, $verify, &$errors) {
  /
  *
  • Explaining !preg_match_all(’$\S*(?=\S{8,})(?=\S*[a-z])(?=\S*[A-Z])(?=\S*[\d])(?=\S*[\W])\S*$’, $password)
  • $ = beginning of string
  • \S* = any set of characters
  • (?=\S{8,}) = of at least length 8
  • (?=\S*[a-z]) = containing at least one lowercase letter
  • (?=\S*[A-Z]) = and at least one one uppercase letter
  • (?=\S*[\d]) = and at least one number
  • (?=\S*[\W]) = and at least a special character (non-word character)
  • $ = end of the string:
  /
  if (!preg_match_all(’$\S(?=\S{8,})(?=\S*[a-z])(?=\S*[A-Z])(?=\S*[\d])(?=\S*[\W])\S*$’, $password)) {
  $errors[‘validPassword’] = false; // False means it’s an invalid password:
  } else {
  $errors[‘validPassword’] = true;
  }
  if ($password != $verify) {
  $errors[‘matchPassword’] = false; // False means passwords don’t match:
  } else {
  $errors[‘matchPassword’] = true;
  }
  }

$password = “Icsan2016!”;
$verifyPassword = “Icsan2016!”;

passwordCheck($password, $verifyPassword, $errors);

if ($errors) {
echo “Everything checks out OK!
\n”;
echo “

” . print_r($errors,1) . “

\n”;
} else {
echo “There is an error somewhere!
\n”;
echo “

” . print_r($errors,1) . “

\n”;
}

if ($errors[‘validPassword’]) {
echo “

Password is valid!

\n”;
} else {
echo “

Password is invalid!!!

\n”;
}

if ($errors[‘matchPassword’]) {
echo “

Both passwords match!

\n”;
} else {
echo “

Passwords do not match!!!

\n”;
}

$password = “Icsan2016a”;
$verifyPassword = “Icsan2016!”;

passwordCheck($password, $verifyPassword, $errors);

if ($errors) {
echo “Everything checks out OK!
\n”;
echo “

” . print_r($errors,1) . “

\n”;
} else {
echo “There is an error somewhere!
\n”;
echo “

” . print_r($errors,1) . “

\n”;
}

if ($errors[‘validPassword’]) {
echo “

Password is valid!

\n”;
} else {
echo “

Password is invalid!!!

\n”;
}

if ($errors[‘matchPassword’]) {
echo “

Both passwords match!

\n”;
} else {
echo “

Passwords do not match!!!

\n”;
}

$password = “Icsan2016!”;
$verifyPassword = “Icsan2016!s”;

passwordCheck($password, $verifyPassword, $errors);

if ($errors) {
echo “Everything checks out OK!
\n”;
echo “

” . print_r($errors,1) . “

\n”;
} else {
echo “There is an error somewhere!
\n”;
echo “

\n”;
}

if ($errors[‘validPassword’]) {
echo “

\n”;
} else {
echo “

\n”;
}

if ($errors[‘matchPassword’]) {
echo “

Both passwords match!

\n”;
} else {
echo “

Passwords do not match!!!

\n”;
}
[/php]

The password requirements can be easily modified. HTH John

P.S. Can anyone guess what the phrase of the password “Icsan2016!” is? (Hint: Look at the time I posted this)
