PHP的形式和MySQL無法插入

[英]php form and mysql not inserting

 原文  2013-05-02 20:32:17  9   1    php/ mysqli/ prepared-statement

問題描述

我在將數據從php表單獲取到mysql數據庫時遇到問題。 我通過准備輸入，綁定它們然后執行來使用mysqli。

提交表格時我沒有任何錯誤。 如果我故意將一個錯誤輸入到prepare語句中，例如拼寫錯誤的“ INERT INTO table ...”，然后提交表單，則會顯示錯誤。 如果將其他字符串或整數值放入bind_param中，則不會出錯；如果將其他變量或拼寫錯誤的變量放入綁定中，則也不會出錯。 我無法為自己的生活弄清楚出了什么問題！ 我已經計算了准備值的數量與綁定值和變量的數量，並且計數匹配。

以下是提交表單時正在執行的輸入表單： 

<?php
//set database connection parameters
$hostname = 'localhost:3307'; // usually is localhost
$db_user = 'test'; // change to your database username
$db_password = 'test'; // change to your database password 
$database = 'test'; // provide your database name 


//database connection
$db = new mysqli($hostname, $db_user, $db_password, $database);
if(mysqli_connect_errno())
{
    printf("Unable to connect to database: %s\n", mysqli_connect_error());
    exit();
}

//Prepare prerequisites
        $created = date("d-m-Y H:i:s");
        $ip = $_SERVER['REMOTE_ADDR'];

if (isset($_POST['submit']))

看一下if語句中正在測試的內容。
您會看到您只是在檢查准備語句是否有錯誤。 您無需檢查查詢是否實際執行。

您可以在查詢的執行中添加其他if語句，以告知您是否存在問題。

它似乎只在插入日期和ip地址（前兩個變量），僅此而已

您看不到其他任何變量的問題是因為它們沒有定義。 由於您是從表單提交數據，因此需要使用$ _POST或$ _GET訪問它們。 看一下有關外部變量的 php 指南 。

另外，如果您使用新代碼和任何新錯誤更新您的主要帖子，我們可以幫助您縮小范圍。
