我的表格沒有提交

[英]My form isn't submitting

 原文  2016-04-20 09:45:30  5   3    php/ mysql

問題描述

填寫必要的內容后，表單仍然不會提交（或重定向到我創建的“ voted.php”以幫助我連接到數據庫）。 單選按鈕可以正確單擊，但不僅僅是重定向。

這是我的代碼：

我們的HTML代碼在這里有點悶，這應該有助於對其進行修復。

正如您所指出的，您只能投票一次，我建議您添加一些措施以防止同一張表格被提交兩次。

另外，為了幫助您調試PHP腳本中的發布數據，接下來的這段代碼通常有助於檢查發布的內容： 

<?php
echo "<pre>";
print_r($_POST);
echo "</pre>;
?>

您將需要mysqli_real_escape_string並在插入之前准備POST數據，以幫助防止MYSQL攻擊。

您的表單元素具有兩個名稱屬性...刪除第一個名稱屬性，即name =“ radio_array []”

更新您的插入查詢： 

$sqli = "INSERT INTO `election`.`voted` (`Reg_Num`, `President_1`, `President_2`, `Vice_President_1`, `Vice_President_2`, `Secretary_General_1`, `Secretary_General_2`, `Finance_1`, `Finance_2`, `Software_1`, `Software_2`, `Assist_Sec_Gen_1`, `Assist_Sec_Gen_2`, `Info_1`, `Info_2`, `Welfare_1`, `Welfare_2`, `Sports_1`, `Sports_2`, `Protocol_1`, `Protocol_2`, `Fin_Sec_1`, `Fin_Sec_2`)
VALUES
('".$_POST['Reg_Num']."', '".$_POST["President_1"]."', '".$_POST["President_2]."', '".$_POST["Vice_President_1"]'"......";

像這樣...。此外，您還應注意進行sql注入

大聲笑，您input type="submit"按鈕不在form ……應該位於form標記內。 除了不希望一次提交所有輸入字段外，還只需填寫一種表單而不是100種表單。

請記住，每個表單都需要一個提交按鈕。 否則它將不會提交任何東西。
