问题描述
每当我点击编辑时，它会显示以下错误
注意：未定义的变量：_Get在第9行的C：\ xampp \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ fetch_array（）在第13行的C：\ xampp \htdocs \ OOP1 \ blog \ adminmin \ editit_post.php中的非对象上
我尝试了什么：
Whenever I click edit it shows these errors below
Notice: Undefined variable: _Get in C:\xampp\htdocs\OOP1\blog\admin\edit_post.php on line 9
Fatal error: Call to a member function fetch_array() on a non-object in C:\xampp\htdocs\OOP1\blog\admin\edit_post.php on line 13
What I have tried:
<?php
include "../libs/config.php";
include "../libs/db.php";
//Creating database object
$db = new database();
//getting the id
$id = $_Get['id'];
$query = "SELECT * FROM posts WHERE id = '$id'";
$posts = $db ->select($query);
$single = $posts ->fetch_array();
//Inserting Posts
if(isset($_POST['submit'])){
//creating variables for texts
$title = $_POST['title'];
$content = $_POST['content'];
$cat = $_POST['cat'];
$author = $_POST['author'];
$tags = $_POST['tags'];
//creating varibles for image
$image = $_FILES['image']['name'];
$image_tmp = $_FILES['image']['tmp_image'];
move_uploaded_file($image_tmp,"../images/$image");
$query = "INSERT INTO posts (category_id,title,content,author,image,tags) VALUES ('$cat','$title','$content','$auhor','$image','$tags')";
$run = $db->insert($query);
}
?>
