顯示一個php的計算值並將其傳遞到數據庫

我想這是一個簡單的函數&我錯過了編碼的地方。尋求幫助。顯示一個php的計算值並將其傳遞到數據庫

我得到用戶的輸入日期&添加/計算工作日。當我從數據庫檢索輸入時，顯示的代碼&顯示。但我想計算用戶通過提交按鈕將輸入&傳遞給數據庫的日子。

這是我的編碼。請幫助

<?php 
include_once('confiq.php'); 

// Only process the form if $_POST isn't empty 
if (! empty($_POST)) { 

// Connect to MySQL 
$mysqli = new mysqli('localhost', 'root', '', 'fiber'); 

// Check our connection 
if ($mysqli->connect_error) { 
die('Connect Error: ' . $mysqli->connect_errno . ': ' . $mysqli->connect_error); 
} 

// Insert our data 
$sql = "INSERT INTO fiberexcel (SiteID0, SiteName1, SiteAddress2, ProjectType3, ReqDate4, TargetDate5, Vendor6, ESRNo7, Contact8, Engineer9, AM10) 
VALUES ('{$mysqli->real_escape_string($_POST['SiteID0'])}',

您可以編輯該代碼你想要做什麼。這從日期計算到另一個日期。如果這就是你要求的。

謝謝。但這不是我的要求。「請求日期」字段將由用戶給出。我想爲該輸入添加日期，將其顯示在「TagetDate」字段中，並將計算的日期值傳遞給數據庫。我有一個不同的頁面來顯示錶格中的用戶輸入。那裏的計算只在頁面中有效，而不是存儲在數據庫中。請幫助 – Sugs

你缺少NAME =「TargetDate5」在「目標完成日期」字段，以便它是沒有得到張貼在你的$ _POST陣列。
此外，下面的值不是從表單發佈，而是存在於您的查詢中。

$_POST['ESRNo7'] 
$_POST['Contact8'] 
$_POST['Engineer9'] 
$_POST['AM10']

$ ReqDate4 = date（「Y-m-d」）; \t //增加75天 $ TargetDate5 = strtotime（$ ReqDate4。「+ 75 weekday」）; 回顯日期（「Y-m-d」，$ TargetDate5）。「\ n」個; echo「」; $ _POST ['$ TargetDate5'] = $ TargetDate5; //此POST功能不起作用。計算值不顯示在頁面中或不存儲在數據庫中。請幫助 – Sugs

是的。我沒有在這裏添加代碼。我應該添加整個代碼嗎？ – Sugs

首先檢查$ _POST數組中的所有數據是否已定義或發佈在Create.php中（在查詢中使用的數據），然後打印查詢並直接在phpmyadmin中運行，看看發生了什麼問題。 – Anupam
