after validating data from a registration form, redirect to another page to log in
Solution 1
Replace your code with this....
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
// validating the form to see all required fields are entered
if (empty($_POST["userID"]))
{
$userErr = "User ID is required";
}
else
{
$userID = test_input($_POST["userID"]);
}
if (empty($_POST["password"]))
{
$passErr = "Password is required";
}
else
{
$password = test_input($_POST["password"]);
}
if (empty($_POST["pass_conf"]))
{
$passErrc = "Confirm your password";
}
else
{
$pass_conf = test_input($_POST["pass_conf"]);
}
if (empty($_POST["firstName"]))
{
$firstErr = "First Name is required";
}
else
{
$firstName = test_input($_POST["firstName"]);
}
if (empty($_POST["lastName"]))
{
$lastErr = "Last Name is required";
}
else
{
$lastName = test_input($_POST["lastName"]);
}
if (empty($_POST["middle"]))
{
$middle = "";
}
else
{
$middle= test_input($_POST["middle"]);
}
if (empty($_POST["address"]))
{
$addErr = "Address is required";
}
else
{
$address = test_input($_POST["address"]);
}
if (empty($_POST["city"]))
{
$cityErr = "City is required";
}
else
{
$city = test_input($_POST["city"]);
}
if (empty($_POST["state"]))
{
$stateErr = "State is required";
}
else
{
$state = test_input($_POST["state"]);
}
if (empty($_POST["zip"]))
{
$zipErr = "Zip is required";
}
else
{
$zip = test_input($_POST["zip"]);
}
if (empty($_POST["email"]))
{
$emailErr = "Email is required";
}
else
{
$email = test_input($_POST["email"]);
}
if (empty($_POST["phone"]))
{
$phoneErr = "";
}
else
{
$phone = test_input($_POST["phone"]);
}
if($password != $pass_conf){
$passMathErr= "Passwords do not match. Please, go back and re-enter the passwords!";
// die($passMathErr);
} else{
// perform sql query to insert the data
$sql="insert into users values('$userID', '$password', '$firstName', '$lastName', '$middle', '$address', '$city', '$state', '$zip', '$email', '$phone')";
$result=mysql_query($sql, $connection);
header("Location: login.html");
}
}
?>
The mistake is - you are executing your redirect condition only if the REQUESTED method is NOT EQUAL to POST.
So the above code executes if the request method is POST & the password entered matches the confirm password, then redirect the user to login page. It would work now!
Solution 2
You have to exit from the code segment once the control is transferred to another page. Otherwise the following code will get executed. So use exit;
after header().
header("Location:login.html");
exit;
Solution 3
try using ob_start(); at the top of the file and ob_end_flush(); at the bottom of the file.
Solution 4
just remove the else part of main if statement ans the password confirmation part put in main if statement :
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
some coce
}
//""""
else
{
if($password != $pass_conf){
$passMathErr= "Passwords do not match. Please, go back and re-enter the passwords!";
// die($passMathErr);
} else{
$sql="insert into users values('$userID', '$password', '$firstName', '$lastName', '$middle', '$address', '$city', '$state', '$zip', '$email', '$phone')";
$result=mysql_query($sql, $connection);
header("Location:login.html");
}
} //"""
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
some coce
}
//""""
else
{
if($password != $pass_conf){
$passMathErr= "Passwords do not match. Please, go back and re-enter the passwords!";
// die($passMathErr);
} else{
// perform sql query to insert the data
$sql="insert into users values('$userID', '$password', '$firstName', '$lastName', '$middle', '$address', '$city', '$state', '$zip', '$email', '$phone')";
$result=mysql_query($sql, $connection);
header("Location:login.html");
}
} //"""
// perform sql query to insert the data
remove the above """ part and add it inside main if statement

I could be wrong but looking at the structure of your if/else statements it looks like you would only ever send the header when the request method is NOT POST. (Ie. Looks like its in the else section.) I think its in the wrong place.
It is this else that i just think needs removing. (Although i am not sure how your validation stops the redirect with your current code)
{$phone = test_input($_POST["phone"]);} } else { if($password != $pass_conf){

i am new to php and mysql. I am trying to create a user registration form, validate the data, and then redirect to a login page, where they can enter their username and password to sign in. i have written the codes, but for some reason i'm not able to use the header() properly. Here is my code so far:
$userErr= $passErr= $passErrc= $firstErr= $lastErr= $middle= $addErr= $cityErr= $stateErr=$zipErr= $emailErr= $phoneErr= $passMatchErr=""; $userID= $password= $pass_conf= $firstName= $lastName= $middle= $address= $city= $state= $zip= $email= $phone=""; // Validate the form // use trim() function to remove unnecessary characters such as extra space, tab, newline, // use stripslashes(() to remove backslashes // use htmlspecialchars() for security function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $data; } if ($_SERVER["REQUEST_METHOD"] == "POST") { // validating the form to see all required fields are entered if (empty($_POST["userID"])) { $userErr = "User ID is required"; } else { $userID = test_input($_POST["userID"]); } if (empty($_POST["password"])) { $passErr = "Password is required"; } else { $password = test_input($_POST["password"]); } if (empty($_POST["pass_conf"])) { $passErrc = "Confirm your password"; } else { $pass_conf = test_input($_POST["pass_conf"]); } if (empty($_POST["firstName"])) { $firstErr = "First Name is required"; } else { $firstName = test_input($_POST["firstName"]); } if (empty($_POST["lastName"])) { $lastErr = "Last Name is required"; } else { $lastName = test_input($_POST["lastName"]); } if (empty($_POST["middle"])) { $middle = ""; } else { $middle= test_input($_POST["middle"]); } if (empty($_POST["address"])) { $addErr = "Address is required"; } else { $address = test_input($_POST["address"]); } if (empty($_POST["city"])) { $cityErr = "City is required"; } else { $city = test_input($_POST["city"]); } if (empty($_POST["state"])) { $stateErr = "State is required"; } else { $state = test_input($_POST["state"]); } if (empty($_POST["zip"])) { $zipErr = "Zip is required"; } else { $zip = test_input($_POST["zip"]); } if (empty($_POST["email"])) { $emailErr = "Email is required"; } else { $email = test_input($_POST["email"]); } if (empty($_POST["phone"])) { $phoneErr = ""; } else { $phone = test_input($_POST["phone"]); } } else { if($password != $pass_conf){ $passMathErr= "Passwords do not match. Please, go back and re-enter the passwords!"; // die($passMathErr); } else{ // perform sql query to insert the data $sql="insert into users values('$userID', '$password', '$firstName', '$lastName', '$middle', '$address', '$city', '$state', '$zip', '$email', '$phone')"; $result=mysql_query($sql, $connection); header("Location:login.html"); } } ?> <html lang="em"> <head> <title> Registration </title> <style type="text/css"> h1{ text-align: left; font-weight:bold; font-size: 2em; color:#FFFF99; word-spacing: 0.3em; letter-spacing:0.1em; text-decoration:underline; } body{ background-color: #421818; } .txtinput{ margin-left:150px; } table{ font-color:#99FF00; } .error { color: #FF0000; } </style> </head> <body> <h1> Registration Form </h1><br> <form name="reg" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="post"> <table style="color:#99FF00" border=0 cellspacing=0 cellpadding=2> <tr> <td>User ID * <td><input type="text" name="userID"/> <span class="error"><?php echo $userErr;?></span> </tr> <tr> <td>Password *<td><input type="password" name="password" /> <span class="error"><?php echo $passErr;?></span> </tr> <tr> <td>Confirm Password *<td><input type="password" name="pass_conf" /> <span class="error"><?php echo $passErrc;?></span> </tr> <tr> <td>First Name *<td><input type="text" name="firstName" /> <span class="error"><?php echo $firstErr;?></span> </tr> <tr> <td>Last Name *<td><input type="text" name="lastName" /> <span class="error"><?php echo $lastErr;?></span> </tr> <tr> <td>Middle<td><input type="text" name="middle" /> <span class="error"><?php echo $middle;?></span> </tr> <tr> <td>Address *<td><input type="text" name="address" /> <span class="error"><?php echo $addErr;?></span> </tr> <tr> <td>City *<td><input type="text" name="city" /> <span class="error"><?php echo $cityErr;?></span> </tr> <tr> <td>State *<td><input type="text" name="state" /> <span class="error"><?php echo $cityErr;?></span> </tr> <tr> <td>Zip *<td><input type="text" name="zip" /> <span class="error"><?php echo $zipErr;?></span> </tr> <tr> <td>Email *<td><input type="text" name="email"/> <span class="error"><?php echo $emailErr;?></span> </tr> <tr> <td>Phone<td><input type="text" name="phone" /> <span class="error"><?php echo $phone;?></span> </tr> </table> <div class="txtinput"> <input type="submit" name="submit" value="Register"/> </div> </form> </body> </html>
