Registration Form PHP Code

[RedNeckRabbit93]

Hello,

I am currently coding a site from scratch. I know i can use templates and everything else but i want the experience. The HTML I've had down for years but it seems PHP is getting a little elusive for me. I'm trying to create a registration form and when i test my site i keep getting parse errors and syntax errors... mainly regarding the use of {} and if/else. Any help would be appreciated. Most of the code is still incomplete, I have to go back and fill in some areas I've left blank for now, but i have commented using // Where the browser is kicking back my errors.

<?php
$con = Mysqli_connect("'', '', ''");
if (Mysqli_connect_errno()) {
  echo "Failed to connect to DB. Please check your connection info." . Mysqli_connect_errno;
  // Only if there is an error.
}
//Declaring Variable for Registration form
$fname = "";
$lname = "";
$em = "";
$emc = "";
$pass = "";
$passc = "";
$date = "";
$error_array = "";

if (insert($_POST['register_button'])) {
  // To handle the registration form

  // First Name Values
  $fname = strip_tags($_POST['reg_fname']);
  $fname = str_replace(' ', '', $fname);
  $fname = ucfirst(strtolower($fname));

  // Last Name Values
  $lname = strip_tags($_POST['reg_lname']);
  $lname = str_replace(' ', '', $lname);
  $lname = ucfirst(strtolower($lname));

  // Registration Email Values
  $em  = strip_tags($_POST['reg_email']);
  $em = str_replace(' ', '', $em);

  // Confirm Registration Email Values
  $emc = strip_tags($_POST['reg_emailc']);
  $emc = str_replace(' ', '', $emc);

  // Registrsation Password Values
  $pass = strip_tags($_POST['reg_pass']);

  // Registration Password Confirmation Values
  $passc = strip_tags($_POST['reg_passc']);

  // Registration Date Values
  $date = date("m-d-Y");
  
// Here is where the browser keeps kicking back parse errors
  if ($em == $emc) {
  }
  else {
    echo "Email and Confirmation Email must match";

  }
    if (filter_var($em, FILTER_VALIDATE_EMAIL)) {
      $em = filter_var($em, FILTER_VALIDATE_EMAIL)
    }

      else {
      echo "Invlaid Format";
    }




?>

I see two syntax errors

if (insert($_POST['register_button'])) {

The { has no corresponding } later in the code.

    if (filter_var($em, FILTER_VALIDATE_EMAIL)) {
      $em = filter_var($em, FILTER_VALIDATE_EMAIL)
                                                  ^  
    }

      

missing ; at the end of the line

When i put a } here the syntax error reads "Unexpected } on line blabla"

 

    if (filter_var($em, FILTER_VALIDATE_EMAIL)) {
      $em = filter_var($em, FILTER_VALIDATE_EMAIL)
                                                  ^  
    }

      

missing ; at the end of the line(Thank you for the catch!) You're right!

I went ahead and for the hell of it, added the corrections to the mistakes you noticed. However now i am getting this error.

Fatal error: Uncaught Error: Call to undefined function insert() in register.php:18 Stack trace: #0 {main} thrown in register.php on line 18. 

 

Line 18 references this line here: 

if(insert($_POST['register_button'])) {

  // To handle the registration form
}

Make sure you have defined the function insert(). It's not a PHP function.

(Or did you mean isset() ?)

Why did i not notice this? I am not completely new to PHP. Why in the world did I miss this function? I know better. Grrrrrr! I guess my frustration blinded me. I will fix it now. You are right, insert is not a PHP function. 

 

@Barand

You were correct. This fixed my entire issue. If i had just been paying attention I wouldn't be feeling like an idiot right now! Thank you Dear Sir!

@Barand

That fixed all the issues except for one. 

if (filter_var($em, FILTER_VALIDATE_EMAIL)) {
  $em = filter_var($em, FILTER_VALIDATE_EMAIL);
  
  else {
    echo "Invalid Format";
  }

}

// This code gives me this error: Parse error: syntax error, unexpected 'else' (T_ELSE) in /*****/**/******/htdocs/site/register.php on line 60

If i do it this way:

if (filter_var($em, FILTER_VALIDATE_EMAIL)) {
  $em = filter_var($em, FILTER_VALIDATE_EMAIL);
  }
  else {
    echo "Invalid Format";
  }


//It fixes the rror but the page is constantly returning echo "Invalid Format"; regardless of what is inputted into my form.

Your first one is missing a } before the else. Syntax is

if (condition) {
    do something
}
else {
    do something else
}

It looks like $em  is not valid. Have you tried  var_dump($em) to check what's in there?

 

PS You could just...

if ( ($em = filter_var($em, FILTER_VALIDATE_EMAIL)) === false ) {
   echo "Invalid format"; 
}

Yeah, it comes out as bool false. Which means I've failed to inform PHP what I'm using $em for
