Question

Erreur lors de la soumission du formulaire de contact.

Undefined index: HTTP_X_REQUESTED_WITH dans C: \ xampp \ htdocs \ dishadwellings \ dishaparkwest \ contact.php sur la ligne 7 { "type": "erreur", "texte": "Désolé demande doit être Ajax POST" }

Voici le code HTML FORM:

<form action="contact.php" method="POST"> 
         <input type="text" name="do-input-name" id="do-input-name" placeholder="Name"> 
         <input type="email" name="do-input-email" id="do-input-email" placeholder="Email"> 
         <input type="text" name="do-input-web" id="do-input-web" placeholder="Web"> 

         <textarea name="do-input-message" id="do-input-message" cols="30" rows="10" class="do-input-message" placeholder="Comment"></textarea> 

         <button type="submit" id="do-submit-btn" class="do-btn-round-solid">SEND</button> 
        </form> 

Voici le code pour le formulaire de contact: Je ne pouvais pas corriger l'erreur. Veuillez faire la faveur de résoudre ce problème

<?php 
if($_POST) 
{ 
    $to_email  = "abc@gmail.com"; //Recipient email, Replace with own email here 

    //check if its an ajax request, exit if not 
    if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') { 

     $output = json_encode(array(//create JSON data 
      'type'=>'error', 
      'text' => 'Sorry Request must be Ajax POST' 
     )); 
     die($output); //exit script outputting json data 
    } 

    //Sanitize input data using PHP filter_var(). 
    $name  = filter_var($_POST["name"], FILTER_SANITIZE_STRING); 
    $email  = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL); 
    $message = filter_var($_POST["message"], FILTER_SANITIZE_STRING); 

    //additional php validation 
    if(strlen($name)<4){ // If length is less than 4 it will output JSON error. 
     $output = json_encode(array('type'=>'error', 'text' => 'Name is too short or empty!')); 
     die($output); 
    } 
    if(!filter_var($email, FILTER_VALIDATE_EMAIL)){ //email validation 
     $output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!')); 
     die($output); 
    } 
    if(strlen($message)<3){ //check emtpy message 
     $output = json_encode(array('type'=>'error', 'text' => 'Too short message! Please enter something.')); 
     die($output); 
    } 

    //email body 
    $message_body = $message."\r\n\r\n-".$name."\r\nEmail : ".$email; 

    //proceed with PHP email. 
    $headers = 'From: '.$name.'' . "\r\n" . 
    'Reply-To: '.$email.'' . "\r\n" . 
    'X-Mailer: PHP/' . phpversion(); 

    $send_mail = mail($to_email, $subject, $message_body, $headers); 

    if(!$send_mail) 
    { 
     //If mail couldn't be sent output error. Check your PHP email configuration (if it ever happens) 
     $output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.')); 
     die($output); 
    }else{ 
     $output = json_encode(array('type'=>'message', 'text' => 'Hi '.$user_name .' Thank you for your email')); 
     die($output); 
    } 
} 
?>

Tentez votre si la condition comme suit:

//check if its an ajax request, exit if not 
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) || (isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest')) { 

    $output = json_encode(array(//create JSON data 
     'type'=>'error', 
     'text' => 'Sorry Request must be Ajax POST' 
    )); 
    die($output); //exit script outputting json data 
} 

La prochaine chose est, vous soumettez formulaire par formulaire HTML normal et que vous essayez de vérifier soumettre données OU envoyer un e-mail uniquement si son ajax soumettre. ce qui n'est pas la vérité et donc ça ne marche pas.

Pour que votre code fonctionne, soumettez les données de votre formulaire via ajax OU supprimez-les si la condition est indiquée ci-dessus.

Votre code postal

<?php 
if($_POST) 
{ 
    $to_email  = "abc@gmail.com"; //Recipient email, Replace with own email here 


    //Sanitize input data using PHP filter_var(). 
    $name  = filter_var($_POST["name"], FILTER_SANITIZE_STRING); 
    $email  = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL); 
    $message = filter_var($_POST["message"], FILTER_SANITIZE_STRING); 
    $subject = "Test email"; 
    $user_name = "Sharnya"; 

    //additional php validation 
    if(strlen($name)<4){ // If length is less than 4 it will output JSON error. 
     $output = 'Name is too short or empty!'; 
     die($output); 
    } 
    if(!filter_var($email, FILTER_VALIDATE_EMAIL)){ //email validation 
     $output = 'Please enter a valid email!'; 
     die($output); 
    } 
    if(strlen($message)<3){ //check emtpy message 
     $output = 'Too short message! Please enter something.'; 
     die($output); 
    } 

    //email body 
    $message_body = $message."\r\n\r\n-".$name."\r\nEmail : ".$email; 

    //proceed with PHP email. 
    $headers = 'From: '.$name.'' . "\r\n" . 
    'Reply-To: '.$email.'' . "\r\n" . 
    'X-Mailer: PHP/' . phpversion(); 

    $send_mail = mail($to_email, $subject, $message_body, $headers); 

    if(!$send_mail) 
    { 
     //If mail couldn't be sent output error. Check your PHP email configuration (if it ever happens) 
     $output = 'Could not send mail! Please check your PHP mail configuration.'; 
     die($output); 
    }else{ 
     $output = 'Hi '.$user_name .' Thank you for your email'; 
     die($output); 
    } 
} 
?> 

formulaire HTML Code:

<form action="contact.php" method="POST" enctype="text/plain"> 
         <input type="text" name="name" id="name" placeholder="Name"> 
         <input type="email" name="email" id="email" placeholder="Email"> 
         <input type="text" name="web" id="web" placeholder="Web"> 

         <textarea name="message" id="message" cols="30" rows="10" class="message" placeholder="Comment"></textarea> 

         <button type="submit" id="submit" class="do-btn-round-solid">SEND</button> 
        </form> 

Bonne programmation!
