我使用這個HTML代碼來允許用戶添加更多字段並將其從此訂單中刪除。使用動態HTML字段調試PHP表格處理

<?php
$str_File = $_POST['BX_FILE'];
$str_Gall = $_POST['BX_GALLERY'];
$str_Med = $_POST['BX_MEDIUM'];
$int_Quant = $_POST['BX_QUANT'];
$str_Notes = $_POST['NOTES'];
//Gets all the values and saves them to the variables in array format.
$int_Num = count($FILE) //Gets the size of th array.
for ($x = 1; $x <= $int_Num; $x++) {
$str_ORD = "Order Field: $x, Filename: $str_File[$x], Gallery: $str_Gall[$x], Photo Medium: $str_Med[$x], Quantity: $int_Quant[$x]"
}
//Loops through all the arrays assembling the message for the email.
mail("[email protected]","Order Test",$str_ORD)
//Sends email.
This是教程中，我一直在關注：
任何幫助，不勝感激！ 對不起，我是一個初學者，當涉及到PHP。
是什麼 「似乎無法得到它的工作」 是什麼意思？它如何失敗？ – David
如果用'$ FILE'表示**超全局變量**，則表示'$ _FILES' –
由於未發送電子郵件而導致頁面更改失敗，因此您可以看到PHP代碼。抱歉，$ str_File僅用於保存HTML表單中的值。 –
