PHP外部....不想把與HTML文件...

<?php 

    $name = $_POST['name']; 
    $month = $_POST['month']; 
    $day = $_POST['day']; 
    $year = $_POST['year']; 
    $starttime = $_POST['starttime']; 
    $email = $_POST['email']; 



    if (strlen($name) < 3) { 
     echo '* Name must be at least 3 characters long' . '<br>'; 
     } 

    if ($month == 0) { 
     echo '* Month must be chosen' . '<br>'; 
     } 
    if ($day == 0) { 
     echo '* Day must be chosen' . '<br>'; 
     } 
    if ($year != 2016) { 
     echo '* Year must be 2016' . '<br>'; 
     } 
    if ($month == 2 && $day == 30) { 
     echo '* Feb 30th is an invalid date' . '<br>'; 
     } 
    if ($month == 2 && $day == 31) { 
     echo '* Feb 31st is an invalid date' . '<br>'; 
     } 
    if (empty($starttime)) { 
     echo '* Must input valid Appointment Time' . '<br>'; 
     } 

    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { 
     echo '* Must input valid email address' . '<br>'; 
     } 
    else { 
     echo '<br>' . 'Submission Successful!' . '<br>'; 
     } 


?> 

有沒有去任何人都可以進行測試，看看這是否正常工作，每次我測試一下它給了我無法POST /appointment.php（我不太擅長PHP，我想保持語法相同，因爲我可以更容易地閱讀它並理解它在做什麼）也是我正確連接它

Answer 1

你的第一個錯誤是你的html控件的名字是title而在php中你試圖獲得所以請首先更改它，如下所示。

$name = $_POST['name'];用下面的代碼替換你的這段代碼。

$ name = $ _POST ['title']; 之後，你會得到消息，因爲你設置 提交成功！

Answer 2

嘗試改變

<input type="text" id="nitle" name="title" value="" maxlength="255"> 

到

<input type="text" id="title" name="title" value="" maxlength="255"> 

而且在appointment.php變化

$name = $_POST['name']; 

到

$name = $_POST['title']; 

Answer 3

你的代碼對我來說似乎很好，除了這個在appointment.php。

$name = $_POST['name']; 

到

$名稱= $ _POST [ '標題'];

由於您的文本框接受名稱值具有名稱'標題'。

並確保您的文件html和php（appointment.php）都在 相同的路徑。

希望，它有助於
