在php中發送郵件文件

Question

我想在php中創建郵件表單。我編寫了ny form的html代碼。我在同一個文件中寫入html表單和php代碼。所以我不想使用另一個文件發送電子郵件。發送郵件

<div class="agent-contact"> 
     <table width="400" border="0" align="center" cellpadding="3" cellspacing="1"> 
     <tr> 
     <td><strong>Contact Form </strong></td> 
     </tr> 
     </table> 

     <table width="400" border="0" align="center" cellpadding="0" cellspacing="1"> 
     <tr> 
      <td> 
      <form name="form1" method="post" action=""> 
       <table width="100%" border="0" cellspacing="1" cellpadding="3"> 
       <tr> 
        <td width="16%">Subject</td> 
        <td width="2%">:</td> 
        <td width="82%"><input name="subject" type="text" id="subject" size="50"></td> 
       </tr> 
       <tr> 
        <td>Detail</td> 
        <td>:</td> 
        <td><textarea name="detail" cols="50" rows="4" id="detail"></textarea></td> 
       </tr> 
       <tr> 
        <td>Name</td> 
        <td>:</td> 
        <td><input name="name" type="text" id="name" size="50"></td> 
       </tr> 
       <tr> 
        <td>Email</td> 
        <td>:</td> 
        <td><input name="customer_mail" type="text" id="customer_mail" size="50"></td> 
       </tr> 
       <tr> 
        <td>&nbsp;</td> 
        <td>&nbsp;</td> 
        <td><input type="submit" name="Submit" value="Send Message"></td> 
       </tr> 
       </table> 
      </form> 
      </td> 
     </tr> 
     </table> 
    </div> 

我的PHP代碼

<?php 

$subject ="$subject"; 

$message="$detail"; 

$mail_from="$customer_mail"; 

$header="from: $name <$mail_from>"; 


$to ='someone@somewhere.com'; 

$send_contact=mail($to,$subject,$message,$header); 


if($send_contact){ 
echo "We've recived your contact information"; 
} 
else { 
echo "ERROffR"; 
}

提交發送消息按鈕時，我如何發送郵件？我有相同的文件。

Answer 1

使用isset

if($_POST['submit']) { 
    $subject =$_POST['subject']; 

    $message=$_POST['detail']; 

    $mail_from=$_POST['customer_mail']; 

    $header="from: " . $_POST['name'] ." <$mail_from>"; 


    $to ='someone@somewhere.com'; 

    $send_contact=mail($to,$subject,$message,$header); 


    if($send_contact){ 
    echo "We've recived your contact information"; 
    } 
    else { 
    echo "ERROffR"; 
    } 
}
