在PHP電子郵件形式的空變量

Question

我有一個簡單的電子郵件形式的PHP文件，我嘗試發送電子郵件，但似乎我的變量爲空。我的代碼後面有一個回顯，用於測試我的變量是否有任何值，並且它們不是打印的。唯一打印的是'完成'和'email $ to'。我做錯了什麼？我在YouTube上發佈了一個帖子，他採用了這種方法，他做了完全相同的事情，併爲他工作。我也嘗試了更多的電子郵件PHP文件，但仍然沒有。 這是我的html和php代碼。

PHP代碼：

<?php 

$name = $_REQUEST['author']; 
$from = $_REQUEST['email']; 
$subj = $_REQUEST['sub']; 
$message = $_REQUEST['msg']; 

$headers .= "From: ".$from; 

$to = "mygmail@gmail.com"; 

$subject = $subj; 
$body = $message; 

if(mail($to,$subject,$body,$headers)) { 
echo "An e-mail was sent to ".$to." with the subject: ".$subject; 
} else { 
echo "There was a problem sending the mail. Check your code and make sure that the e-mail address ".$to." is valid"; 
} 

?> 

的html代碼：

<form action="formtoemail.php" method="post" enctype="text/plain"> 
          <p> 
           <label for="author">Name:</label> 
           <input type="text" id="author" name="author" class="required input_field" /> 
          </p> 
          <p> 
           <label for="email">Email:</label> 
           <input type="text" id="email" name="email" class="validate-email required input_field" /> 
          </p> 
          <p class="no_margin_right"> 
           <label for="subject">Subject:</label> 
           <input type="text" name="sub" id="sub" class="input_field" /> 
          </p> 
          <div class="cleaner h20"></div> 

          <label for="text">Message:</label> 
          <textarea id="msg" name="msg" rows="0" cols="0" class="required"></textarea> 
          <div class="cleaner h20"></div> 

          <input type="submit" value="Send" id="submit" name="submit" class="submit_btn float_l" /> 
          <input type="reset" value="Reset" id="reset" name="reset" class="submit_btn float_r" /> 
         </form> 

Answer 1

您通過POST發送，並通過GET retriving嘗試$_POST，而不是$_GET在PHP

或HTML -

Chen GE從行動GET而不是POST

Answer 2

在你的HTML代碼更改 「POST」 方法 「GET」

<form action="formtoemail.php" method="get" enctype="text/plain"> 
         <p> 
          <label for="author">Name:</label> 
          <input type="text" id="author" name="author" class="required input_field" /> 
         </p> 
         <p> 
          <label for="email">Email:</label> 
          <input type="text" id="email" name="email" class="validate-email required input_field" /> 
         </p> 
         <p class="no_margin_right"> 
          <label for="subject">Subject:</label> 
          <input type="text" name="sub" id="sub" class="input_field" /> 
         </p> 
         <div class="cleaner h20"></div> 

         <label for="text">Message:</label> 
         <textarea id="msg" name="msg" rows="0" cols="0" class="required"></textarea> 
         <div class="cleaner h20"></div> 

         <input type="submit" value="Send" id="submit" name="submit" class="submit_btn float_l" /> 
         <input type="reset" value="Reset" id="reset" name="reset" class="submit_btn float_r" /> 
        </form> 

Answer 3

使用 「get」 方法：

<form action="formtoemail.php" method="get" enctype="text/plain"> 

Answer 4

您需要更改這個：

$headers .= "From: $email"; 

對此：

$headers = "From: ".$from; 

，改變這一點：

$subject = "$subj"; 
$body = "$message"; 

mail($to, $subject, $body, $headers); 

if(mail($to, $subject, $body, $headers)) { 
    echo "An e-mail was sent to $to with the subject: $subject"; 
} else { 
    echo "There was a problem sending the mail. Check your code and make sure that the e-mail address $to is valid"; 
} 

要這樣：

$subject = $subj; 
$body = $message; 

if(mail($to, $subject, $body, $headers)) { 
    echo "An e-mail was sent to ".$to." with the subject: ".$subject; 
} else { 
    echo "There was a problem sending the mail. Check your code and make sure that the e-mail address ".$to." is valid"; 
}
