Adding email validation

[Russia]

I would also like to add a email validation to it. How would I go about doing that without messing up the coding?

 

So basically even if the whole form is filled out, and the email is in the wrong format, then do the same thing as when the form isn't totally filled out. If the email is in the correct format but the whole form isnt filled out, then show an error message, I already have all that coded in, exept the email validation.

 

Can someone add that to my code?

 

<?php
  $form = '<form action="" method="POST">   
Email Address:  
<input size="40" type="text" value="' . $_POST["email_address"] . '" name="email_address"><br>  
Username  
<input size="40" type="text" value="' . $_POST["username"] . '" name="username"><br>  
password  
<input size="40" value="' . $_POST["password"] . '" type="text" name="password"><br>  
<input id="submit" class="submit-button" type="submit" name="submit" value="Reset Password" >  
</form>';
  if (isset($_POST['submit'])) {
      $blank_inputs = 0;
      $test_array = array_count_values($_POST);
      $blank_inputs = $test_array[""];
      if ($blank_inputs > 0) {
          //display an error message and put the form back up for editing 
          echo "Please fill out the whole form.<hr>";
          echo $form;
      } else {
          echo 'message sent';
      }
  } else {
      echo $form;
  }
?>

Bump.

You mean email activation.. like you send an email to them.. they click a link and their account is active?

[Russia]

No, to see if its in the correct format.

 

Something like:

 

ereg("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$]", $email);

 

But where would I add that?

[Russia]

Bump.

      if (($blank_inputs > 0) || (preg_match("/^[a-z0-9._-]+?@[a-z0-9-]+?(?:\.[a-z]{1,4}){1,2}$/i",$_POST['email']))) {
          //display an error message and put the form back up for editing 
          echo "Please fill out the whole form.<hr>";
          echo $form;
      } else {
           echo 'message sent';
      }

So something like this?

 

<?php
  $email = $_POST['email_address'];
  $form = '<form action="" method="POST">   
Email Address:  
<input size="40" type="text" value="' . $_POST["email_address"] . '" name="email_address"><br>  
Username  
<input size="40" type="text" value="' . $_POST["username"] . '" name="username"><br>  
password  
<input size="40" value="' . $_POST["password"] . '" type="text" name="password"><br>  
<input id="submit" class="submit-button" type="submit" name="submit" value="Reset Password" >  
</form>';
  if (isset($_POST['submit'])) {
      $blank_inputs = 0;
      $test_array = array_count_values($_POST);
      $blank_inputs = $test_array[""];
      if (($blank_inputs > 0) || (preg_match("/^[a-z0-9._-]+?@[a-z0-9-]+?(?:\.[a-z]{1,4}){1,2}$/i",$_POST['email']))) {
          //display an error message and put the form back up for editing 
          echo "Please fill out the whole form.<hr>";
          echo $form;
      } else {
          echo 'message sent';
      }
  } else {
      echo $form;
  }
?>

Also, what does || mean in php?

 

I believe it is the same as &&; it means and.

[Russia]

So what does && mean in php?

[SamW]

So what does && mean in php?

 

The same as ||.

[mrMarcus]

they are not the same:  Logical Operators

[oni-kun]

So what does && mean in php?

 

The same as ||.

 

Nope. 3 || 4, OR. 3 && 3, AND.  So I'd recommend switching the || to an AND unless you want zero-length e-mails to boot.
