PHP-Formular-Validierung funktioniert nicht beim Senden

Question

Ich habe ein HTML-Formular, das auf eine PHP-Datei verweist. Wenn ich auf "Senden" klicke, wird das Formular gesendet und ich erhalte eine E-Mail. Wenn das Formular jedoch leer ist und ich auf "Senden" klicke, wird es immer noch zur Startseite weitergeleitet.

Form HTML:

 <form class="form-horizontal" role="form" method="post" action="contact.php"> 
       <div class="form-group"> 
        <label for="name" class="col-sm-2 control-label">Name</label> 
        <div class="col-sm-10"> 
         <input type="text" class="form-control" id="name" name="name" placeholder="First & Last Name"> 
             </div> 
       </div> 
       <div class="form-group"> 
        <label for="telephone" class="col-sm-2 control-label">Phone</label> 
        <div class="col-sm-10"> 
         <input type="telephone" class="form-control" id="telephone" name="telephone" placeholder="Phone Number" > 
        </div> 
       </div> 
       <div class="form-group"> 
        <label for="email" class="col-sm-2 control-label">Email</label> 
        <div class="col-sm-10"> 
         <input type="email" class="form-control" id="email" name="email" placeholder="example@domain.com" > 
        </div> 
       </div> 
       <div class="form-group"> 

        <label for="dropdown" class="col-sm-2 control-label">Select One:</label> 
        <div class="col-sm-10"> 
        <select name="select" class="form-control" id="dropdown"> 
        <option>Driver</option> 
        <option>Advertiser</option> 
        </select> 
       </div> 
       </div> 
       <div class="form-group"> 
        <label for="message" class="col-sm-2 control-label">Message</label> 
        <div class="col-sm-10"> 
         <textarea class="form-control" rows="4" name="message"></textarea> 
        </div> 
       </div> 
       <div class="form-group"> 
        <div class="col-sm-10 col-sm-offset-2"> 
         <input id="submit" name="submit" type="submit" value="Send" class="btn btn-primary"> 
        </div> 
       </div> 
       <div class="form-group"> 
        <div class="col-sm-10 col-sm-offset-2"> 

        </div> 
       </div> 
      </form>   

contact.php

<?php 
    if (isset($_POST["submit"])) { 
    $name = $_POST['name']; 
    $email = $_POST['email']; 
    $telephone= $_POST['telephone']; 
      $select = $_POST['select']; 
    $message = $_POST['message']; 
    $from = 'Contact Form'; 
    $to = 'myemail@gmail.com'; 
    $subject = 'Message from Contact Form'; 

    $body ="From: $name\n E-Mail: $email\n Telephone: $telephone\n Select: $select\n Message:\n $message"; 

    // Check if name has been entered 
    if (!$_POST['name']) { 
     $errName = 'Please enter your name'; 
    } 

    // Check if email has been entered and is valid 
    if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) { 
     $errEmail = 'Please enter a valid email address'; 
    } 

    //Check if message has been entered 
    if (!$_POST['message']) { 
     $errMessage = 'Please enter your message'; 
    } 

    // If there are no errors, send the email 
    if (!$errName && !$errEmail && !$errMessage && !$errTel) { 
     if (mail ($to, $subject, $body, $from)) { 
      $result='<div class="alert alert-success">Thank You! I will be in touch</div>'; 
     } else { 
      $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>'; 
     } 
    } 
    { 
    // To redirect form on a particular page 
    header("Location:http://www.mywebsite.co"); 
    } 
    } 
    ?> 

Jede Idee, warum meine Validierung nicht funktioniert?

Vielen Dank.

Answer 1

Sie haben zwei zusätzliche Klammern in yor Code, dieses:

{ 
// To redirect form on a particular page 
header("Location:http://www.mywebsite.co"); 
} 

sollte gerade sein:

// To redirect form on a particular page 
    header("Location:http://www.mywebsite.co"); 

Sie schlossen Ihr, wenn Block und Öffnen eines leeren Block.

Answer 2

können Sie wollen diesen Teil erneut prüfen:

{ 
// To redirect form on a particular page 
header("Location:http://www.mywebsite.co"); 
} 

Auch Sie auch Trimmfunktion auf Ihren POST-Daten verwendet werden sollen.

contact.php

if (isset($_POST["submit"])) { 
    $name  = trim($_POST['name']); 
    $email  = trim($_POST['email']); 
    $telephone = trim($_POST['telephone']); 


    /* Other code */ 

    if (!$errName && !$errEmail && !$errMessage && !$errTel) { 
     if (mail ($to, $subject, $body, $from)) { 
     $result='<div class="alert alert-success">Thank You! I will be in touch</div>'; 
     } else { 
     $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later.</div>'; 
     } 
    } else { 
    // To redirect form on a particular page 
    header("Location:http://www.mywebsite.co"); 
    }
