當發送表格時，從「電子郵件地址」聽寫

Question

我有一個表格下面有必填字段，並在用戶填寫時通過電子郵件發送給公司。問題是，從電子郵件地址顯示爲我們的服務器名稱，是否有方法來指定來自地址是什麼？

這些是控制數據的字段：

$to = the_field('email_address'); 
$subject = "UKHG contact enquiry"; 
$companyname_field = $_POST['companyname']; 
$fullname_field = $_POST['fullname']; 
$email_field = $_POST['email']; 
$tel_field = $_POST['tel']; 
$enquiry_field = $_POST['enquiry']; 

這裏的是一個完整的形式：

<div id="contactform"> 
<script language="JavaScript"> 
<!--

function formCheck(formobj){ 
    // Enter name of mandatory fields 
    var fieldRequired = Array("fullname", "email", "tel", "enquiry"); 
    // Enter field description to appear in the dialog box 
    var fieldDescription = Array("Name", "Email", "Telephone", "Enquiry"); 
    // dialog message 
    var alertMsg = "Please complete the following fields:\n"; 

    var l_Msg = alertMsg.length; 

    for (var i = 0; i < fieldRequired.length; i++){ 
     var obj = formobj.elements[fieldRequired[i]]; 
     if (obj){ 
      switch(obj.type){ 
      case "select-one": 
       if (obj.selectedIndex == 0 || obj.options[obj.selectedIndex].text == ""){ 
        alertMsg += " - " + fieldDescription[i] + "\n"; 
       } 
       break; 
      case "select-multiple": 
       if (obj.selectedIndex == -1){ 
        alertMsg += " - " + fieldDescription[i] + "\n"; 
       } 
       break; 
      case "text": 
      case "textarea": 
       if (obj.value == "" || obj.value == null){ 
        alertMsg += " - " + fieldDescription[i] + "\n"; 
       } 
       break; 
      default: 
      } 
      if (obj.type == undefined){ 
       var blnchecked = false; 
       for (var j = 0; j < obj.length; j++){ 
        if (obj[j].checked){ 
         blnchecked = true; 
        } 
       } 
       if (!blnchecked){ 
        alertMsg += " - " + fieldDescription[i] + "\n"; 
       } 
      } 
     } 
    } 

    if (alertMsg.length == l_Msg){ 
     return true; 
    }else{ 
     alert(alertMsg); 
     return false; 
    } 
}

Answer 1

你可以通過一個額外的頭設置在PHP郵件命令：

$header = 'From: email@domain.com'; 
mail($to, $subject, $body, $header);
