php - How to stop a return after a function processes (Prevent HTML from not loading) -


hello have function checks if registration details doesn't match in database, if does, return code.

but every time return code, html won't load because it's stopping loading. want html under php code, specific reason (i want errors display form, , not under).

this example of function:

function check_available($name, $password, $email) {     global $pdo;      $check_user = $pdo->prepare("select * users user_name = :username limit 1");     $check_user->execute( array(':username' => $name) );              $check_email = $pdo->prepare("select * users user_email = :email limit 1");     $check_email->execute( array(':email' => $email) );       $error = '';     if ($check_user->rowcount())     {         $error .= 'username exists!';         return handle_errors($error);     }     else if($check_email->rowcount() && !$check_user->rowcount())     {         $error .= 'email exists!';         return handle_errors($error);     }     else     {         return true;     } }      if (isset($_post['submit']))     {         $check_in = check_available($name, $password, $email);           if ($check_in == true)         {             echo 'created account sucessfully!';         }     } ?>   <html> <form action="register.php" method="post"> username: <input type="text" name="username"><br /> password: <input type="password" name="password"><br /> email: <input type="text" name="email"><br /> <input type="submit" name="submit"> </form> </html>

after submiting, (with having username matches in database), html hide & error display.

how prevent this? there trick that?

there no point in hiding form.
quite contrary, form have shown let user enter name.

so, add error output form - that's need

edit
looks it's handle_errors() function blame.

function reg_has_errors($name, $password, $email) {     global $pdo;      $error = '';      $sql = "select 1 users user_name = ? limit 1";     $stm = $pdo->prepare($sql);     $stm->execute( array($name) );             if($stm->rowcount())     {         $error .= 'username exists!';     }      $sql = "select * users user_email = ? limit 1";     $stm = $pdo->prepare($sql);     $stm->execute( array($email) );             if($stm->rowcount())     {         $error .= 'email exists!';     }     return $error; }  $errors = ''; if (isset($_post['submit'])) {     $errors = reg_has_errors($name, $password, $email);      if (!$errors)     {         echo 'created account sucessfully!';     } } echo errors;

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
