如何使用mysqli在不同页面上使用链接提取数据

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何使用mysqli在不同页面上使用链接提取数据相关的知识，希望对你有一定的参考价值。
我找到了链接到页面的方法，并设置了我想要调用的ID：
<a href="page.php?id=10">CLICK TEST</a> **(IS THIS RIGHT?)**
但后来我需要page.php来拉取id，这就是我现在用来手动拉取id的内容。我如何将以下代码从链接中拉出来？
<?php
$query = "select * from Drinklist where id = 10";
$result = mysqli_query($conn,$query);
while($Drinklist = mysqli_fetch_array($result)){
echo "<head>";
echo "<title>".$List['name']." - Site Name</title>";
}
?>
我尝试了以下（不起作用）：
$query = "select * from List where id = . $id";
好像我只能找到使用MYSQL而不是MYSQLI的方式...任何帮助将不胜感激。
更新的代码：
<?php
$query = "select * from Drinklist where id = ?";
$result = mysqli_prepare($conn,$query);
mysqli_stmt_bind_param($result, 'i', $_GET['id']);
mysqli_stmt_execute($result);
while($Drinklist = mysqli_fetch_array($result)){
echo "<head>";
echo "<title>".$Drinklist['name']." - Mixed Drinks Station</title>";
}
?>
得到错误：
警告：mysqli_fetch_array（）要求参数1为mysqli_result，第6行的public_html / page.com / test / inc / drink-page.php中给出的对象
答案
好的，所以我最终通过大量的反复试验来解决这个问题......
感谢chris85的早期支持，希望这可以帮助你一点点。这很好玩 ;）
<?php
$server = "localhost";
$user = "user";
$pass = "password";
$dbname = "database";
//Creating connection for mysqli
$conn = new mysqli($server, $user, $pass, $dbname);
//Checking connection
if($conn->connect_error){
die("Connection failed:" . $conn->connect_error);
}
$article_id = $_GET['id'];
if( ! is_numeric($article_id) )
die("Looks like you are lost! <a href='#'>Back to Home</a> ");
$query = "SELECT * FROM `Whatever` WHERE `ID` =$article_id LIMIT 0 , 30";
$info = mysqli_query($conn,$query);
while($row = mysqli_fetch_array($info, MYSQL_ASSOC))
{
$name = $Whatever['name'];
$description = $Whatever['description'];
$keywords = $Whatever['keywords'];
$lrgpic = $Whatever['lrgpic'];
$vid = $Whatever['vid'];
$name = htmlspecialchars($row['name'],ENT_QUOTES);
$description = htmlspecialchars($row['description'],ENT_QUOTES);
$keywords = htmlspecialchars($row['keywords'],ENT_QUOTES);
$lrgpic = htmlspecialchars($row['lrgpic'],ENT_QUOTES);
$vid = $row['vid']; //Use <-- to be able to have HTML in your database otherwise the above would remove <, >, /, ', ", ect.
echo "<head>";
echo "<title>$name - Site title</title>";
echo "<meta name='description' content='$description'>";
echo "<meta name='keywords' content='$keywords'>";
include 'inc/head.php'; //includes already are in a php file ;)
echo "</head>";
echo "<body>";
include 'inc/header.php';
include 'inc/nav.php';
echo "<div class='wrapper'>";
echo "<div id='drink-name'>";
echo "<h2>$name</h2>";
echo "</div>";
// AND SO ON
}
?>
