我創建了一個顯示頁面，php其中所有用戶記錄都顯示在表格中，并且有洗掉和編輯按鈕來管理用戶，對于洗掉選項我設法做到了，但從昨天開始嘗試編輯按鈕已經有幾個小時了。我希望將所有用戶的資料（全名、電子郵件、密碼...城市）從display.php頁面傳遞update.php到updateform.html了解如何連接這 3 個檔案以成功更新用戶詳細資訊。
以下是檔案：

uj5u.com熱心網友回復：
我可以看到你的代碼有很多問題，所以我不遺余力地為你重新編碼，甚至為你做了更新部分，希望你從中學到一些技巧。根據您的代碼，我假設您對游戲相當陌生...我添加了額外的檔案以使您的生活從長遠來看更輕松。
*一些提示
- 您不需要使用 ?> 在檔案末尾關閉 php
<?=$username?>是一樣的<? echo $username; ?>。養眼，簡單。- 盡量不要使用表格，我沒有弄亂你的但檢查 flex 表格或使用 div
- 不要在 html 表格中使用邊框大小...盡量不要在 html 中的任何內容中使用樣式...始終使用 css。類被多次使用 .classname 和 ID 只被使用一次 #idname*
_config.php 將您的資料庫和其他設定放在此檔案中以包含到您的所有頁面中，這樣您就不會浪費時間一遍又一遍地撰寫相同的內容
<?php
$db = new mysqli('localhost', 'user', 'pass', 'riseofwar_v1');
if ($db->connect_errno > 0) {
die('Unable to connect to database [' . $db->connect_error . ']');
}
_funcs.php 我給你我的基本庫，用來清理你的輸入欄位
<?php

function email ($input){ return filter_var($input, FILTER_VALIDATE_EMAIL); }
function phone ($input){ $phone = preg_replace('/[^0-9]/', '', $input); if(strlen($phone) < 10 || !num($phone)) { $input=false; } return $input; }
function is_url($input){ return preg_match('/^(http|https):\/\/[a-z0-9] ([\-\.]{1}[a-z0-9] )*\.[a-z]{2,5}'.'((:[0-9]{1,5})?\/.*)?$/i',$input); }
function is_uri ($input){ return preg_match('/^[a-z0-9-] $/i', $input); }
function findIt($find,$string){ return preg_match("/$find/i","$string"); }
_html.php你會喜歡這個...修改您創建的每個 html 頁面的頁眉和頁腳...這是您包含在所有現有和新頁面中的檔案。
