使用ID查看記錄

Question

我可以查看用戶列表，但是當我嘗試使用其ID查看用戶記錄時，不會顯示數據庫的輸出。 我以前做過這個，但是我不知道為什么這次不起作用。

user_list.php

<?php

    include 'connection.php';
    $sql = "SELECT * FROM formequip, equipment, department WHERE formequip.equip_id = equipment.equip_id = department.depart_id";
    $result = mysql_query($sql) or die('Query failed. ' . mysql_error());

?>

<div  class="container" style="margin-top: 10px">
     <table width="100%" border="0" class=" table table-striped table-bordered" id="mak_pekerja">
        <thead>

謝謝您的幫助 ：）

Answer 1

您真的要查詢嗎？

$sql = "SELECT * FROM formequip, equipment, department WHERE formequip.equip_id = equipment.equip_id = department.depart_id";

您正在比較兩個表中的equip_id和第三個表中的depart_id。

接下來，你所謂的“formequip.equip_id”的第一個文件，並在第二formequip.id。

我認為您的問題應該通過使用以下行來解決：編輯：使用$ _GET代替$ _POST

$sql = "SELECT * FROM formequip WHERE equip_id=".$_GET['id'];

Answer 2

您如何在數據庫中聲明ID？ 如果是整數，則必須從查詢中刪除撇號：

$sql = "SELECT * FROM formequip WHERE id=".$_POST['id'];

問候。
