Question

我正在尝试从php oops中删除数据库中的图像。我创建了这个类。它从数据库中删除数据但不像功能不起作用。 Plz帮助我。

<!-- session start --> 
 <?php 
if (($session->logged_in) && ($session->isAdmin())) {


}
 else{
header("Location: index.php");

}
?>
<!-- session end here -->

 <?php

 $obj=new Crud("localhost","root","","3g");
 class Crud{
    public $mysqli;

public $data;

public function __construct($host,$username,$password,$db_name){

    $this->mysqli = new mysqli($host, $username, $password, $db_name);

    if(mysqli_connect_errno()) {

        echo "Error: Could not connect to database.";

    exit;

    }
    /*else{
        echo"Your Database successfully connected"; 
    }*/

}

public function __destruct(){
    $this->mysqli->close(); 
}





 public function read(){

    $query="SELECT * FROM fashion";

    $result= $this->mysqli->query($query);

    $num_result=$result->num_rows;


    if($num_result>0){
        while($rows=$result->fetch_assoc()){

            $this->data[]=$rows;

            //print_r($rows);


        }

        return $this->data;
    }

 }


 public function delete($id){

 $sql=mysql_query("select * from fashion where where id='$id'");
$row=mysql_fetch_array($sql);

unlink("fashion/$row[thumbnail_image]");


    $query="DELETE FROM fashion WHERE id='$id'";

    $result= $this->mysqli->query($query) or die(mysqli_connect_errno()."Data cannot inserted");

    if($result){
        header('location:fashion.php'); 
    }


}




 }

 ?>

我尝试了很多代码并尝试了一些不同的方法，但问题仍未解决。

Answer 1

您正在尝试取消链接名为＆＃34; $ row [thumbnail_image]＆＃34;的文件。尝试改变

unlink("fashion/$row[thumbnail_image]");

到

unlink("fashion/" . $row["thumbnail_image"]);

删除和不同于PHP oops中的图像
