Ich habe ein großes Problem mit einem Kontaktformular. Ich habe seit langem versucht, die Form zu bekommen und mit PHP laufen. Ich habe eine Captcha-Funktion auch, dass ich Sache jetzt mit Prüfung funktioniert.PHP Kontaktformular Webseite
Aber ich brauche Hilfe Whit Formular und PHP-Teil: 1. Überprüfen Sie alle Formularfelder und geben Sie eine Fehlermeldung, wenn die Eingabefelder nicht OK sind (rechte Seite aus dem Eingabefeld in roter Farbe). 2. Senden Sie eine E-Mail, wenn alles in Ordnung ist, nachdem Sie die Formularfelder ausgefüllt haben. Und geben Sie bei Nachricht, dass die E-Mail gesendet wurde.
contactform.php
<?php session_start();
if (isset($_POST['Submit'])) {
if (empty($_POST["first_name"])) {
$nameError = "Name is required";
}
else {
$name = test_input($_POST["first_name"]);
// check name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
$nameError = "Only letters and white space allowed";
}
}
// code for check server side validation
if(empty($_SESSION['6_letters_code']) || strcasecmp($_SESSION['6_letters_code'], $_POST['6_letters_code']) != 0){
$msg="<span style='color:red'>The Validation code does not match!</span>";// Captcha verification is incorrect.
}else{// Captcha verification is Correct. Final Code Execute here!
$msg="<span style='color:green'>The Validation code has been matched.</span>";
}
}
?>

Send_form_email.php Dieser Code funktioniert, wenn ich es verwenden:
Aber dann wird der Benutzer weg von der Form gezwungen. Und alle Fehlermeldungen werden auf einer leeren PHP-Seite und nicht in der Form mit dem Captcha auch gegeben.
