私はコンタクトフォーミュラについて大きな問題があります。 私は長い間、フォームを取得し、whit phpを実行しようとしました。 私は物事が今、腐ったチェックをしているということもまた、captchaの機能を持っています。PHPコンタクトフォームのWebページ
しかし、私はフォームとPHPの部分を助ける必要があります： 1.入力フィールドがOKでないときは、すべてのフォームフィールドをチェックして、エラーメッセージを表示します（入力フィールドの右側は赤色です）。 2.フォームフィールドのチェック後にすべてがOKであれば、電子メールを送信します。電子メールが送信されたことをメッセージで伝えます。
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 私はそれを使用する場合、このコードが機能している：
しかし、その後、ユーザーは離れフォームから強制されます。 そして、すべてのエラーメッセージは空白のPHPページで与えられ、フォームにはキャプチャもありません。

// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "my email address";

echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
