PHP的電子郵件驗證和從HTML表格檢索

Question

我一直在試圖創建一個表單，將收集用戶的姓名，電子郵件和問題，但我是如此新的PHP，我一直在努力與它。

目標是收集信息，當他們按下提交時，他們的電子郵件地址應該發送到我的電子郵件，我希望它被驗證，它是一個真正的電子郵件地址。

HTML代碼：

<form method="post" action="process.php"> 
<fieldset> 
<legend>Personal Information</legend> 


<p><label for="name">Name:</label> 
<input type="text" name="name" id="name" maxlength="50" autofocus required /></p> 

<p><label for="recipient">Email Address:</label> 
<input id="recipient" name="recipient" type="text" name="recipient" required></p> 


</fieldset> 

<fieldset> 
<legend>Tours Interested In:</legend> 

<p><label for="question">Questions/Comments:</label> 
<textarea id="question" name="question" cols="50" rows="3"  placeholder="type your comments here" required></textarea> 
</fieldset> 

<p class="centralize"><input type="submit" onclick="send()"  value="Submit Only" /></p> 
<p class="centralize"><input type="reset" value="Clear Form"></p> 

<p id="data_return"></p> 


</form> 

PHP代碼：

<?php 
header("Content-type: text/html"); 

$name=$_POST["name"]; 
$question=$_POST["question"]; 
$email =$_POST["email"]; 

$subject = "You have a USER INQUIRY:"; 
$to = 'myemail@myemail.com'; 


if(!$_POST['name']){ 
$errName = 'Please enter your name'; 
} 






echo "<p>Thank you, $name . Your Email has been Sent, and we will get  back to you within 48 hours.</p>"; 

//Build email (to myself) 


mail($to, $name, $subject, $question, $email);

檢查郵件（）函數在PHP here是如何工作的。 並檢查下面的代碼。祝你好運:)

<?php 
header("Content-type: text/html"); 
if(isset($_POST['submit'])){ //check if the submit button actually clicked 
    $name=$_POST["name"]; 
    $question=$_POST["question"]; 
    $email = test_input($_POST["recipient"]); 
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { //php validations http://www.w3schools.com/php/php_form_url_email.asp 
    echo "Invalid email format"; 
    } 

    $subject = "You have a USER INQUIRY:"; 
    $to = 'myemail@myemail.com'; 
    $message = "Name: {$name} \n"; 
    $message .= "Email: {$email} \n"; 
    $message .= "Question: {$question} \n"; 


    if(!$_POST['name']){ 
    $errName = 'Please enter your name'; 
    } 

    echo "<p>Thank you," . $name . "Your Email has been Sent, and we will get  back to you within 48 hours.</p>"; 

    //Build email (to myself) 

    mail($to, $subject, $message); 
} 

而且在你的HTML，你可以說輸入類型=電子郵件，這是由許多瀏覽器支持。

<input id="recipient" name="recipient" type="email" required></p>
