Hello, new to PHP but w3schools has been VERY HELPFUL!. Been through tutorials over and over and all over the internet,. However I need help.  I just haven't been able to find a successful answer for this.  I am in the final stages of setting up my form.  The user can fill it out.  The form is coded to check for errors and this all works.  YEAH!  Took awhile to get to the point and super happy all this works 😀

BUT...

1.  When the email is entered in the 'email' field, AND both or one of the other fields are left blank and showing error, the form is being sent to my email, even though two other fields on the form are blank and showing errors.  How can I make sure the form is not sent (submitted) when there are still errors outstanding.

2. ALSO...when the form is complete and submitted with no errors,  AND I get the email with the values, I want to redirect the user to a different page the says, basically, "Thank you" and acknowledges that their form has been sent successfully.  I don't want this as an 'echo', but would like it as a redirect (crrently I have it coded as an 'echo'.  I have tried the  header("Location: http://www.example.com/thankyou.html"); and this doesn't work (not sure why as this seems fairly straight forward). The forms action is set to  <?php echo htmlspecialchars($_SERVER["php_self"]);?>.  I do want the form to check all errors on the same page, but would really like a new page redirect on submit.  Any help greatly appreciated.  

My code may be unorganized as of yet, and possibly quite amateur, but here is what I am working on:

PHP code is:


$nameErr = $emailErr  = $monthErr = "";
$name = $email  = $month = $headers = $to =$subject = $body = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
   $name = test_input($_POST["name"]);
   $email = test_input($_POST["email"]);
   $month = test_input($_POST["month"]);
   $to = "info@myemail.com";  // insert my own email address here
   $headers = "From: $email  \r\n";
   $subject = "Rentals Reservation Request";
   $body .= "\r\n Name: " . $name;
   $body .= "\r\n Email: " . $email;  //users email address
   $body .= "\r\n Month: " . $month;

}
 
function test_input($data){
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;

}

    if (empty($_POST["name"])) {
    $nameErr = "<font color='red'>Name is required</font>"; 
    $error .= "<li>Name is required. </li>";  
     } else {
    $name = test_input($_POST["name"]);
 
}
  if (empty($_POST["email"])) {
    $emailErr = "<font color='red'>Email is required</font>";
    $error .= "<li>Email is required.</li>";
  } else {
    $email = test_input($_POST["email"]);
  }

  if (empty($_POST["month"])) {
    $monthErr = "Enter a month from the drop-down list";
     $error .= "<li>Month is required.</li>";
          } else {
    $month = test_input($_POST["month"]);
    
  }

$name = test_input($_POST["name"]);
if (!preg_match("/^[a-zA-Z-' ]*$/",$name)) {
  $nameErr = "<font color='red'>Only letters and spaces allowed";
}

$email = test_input($_POST["email"]);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
  $emailErr = "<font color='red'>Invalid email format";
  $error .= "<li>Invalid email format. </li>";  

echo '<p class="error"><strong>Your message was NOT sent<br/> The following error(s) occurred:</strong><br/>'. '<ul>' . $error . '</ul>' . '</p>';

 } else {
                 echo "Thank you. Your form has been sent.";
                 mail($to, $subject, $body, $headers);
              
}

Sorry, one more issue...

When the form is opened in the browser, all fields are blank but all the error messages are there, like it tried to send right away when I opened the form in the browser.  I deleted browsing history and still the same.  

Sorry, so still lots of issues with the form, but trying persevere and not to let PHP beat me.  😬

Please limit each question to a single question.  I suggest you post a notice that you suspend this thread and re submit per my suggestion.    

EDIT

Also, please limit your code posts to the relevant part and please use the code tags <>.
