Question

我有管理员档案，我可以编辑我的网站。我尝试过解决方案：$DBConnect = new mysqli("localhost","root","","Ladle");但它没有用。我也尝试添加unset（$ connection）;.这也没有用。当我尝试添加新产品时，我收到错误'无法获取mysqli'。

这是我的代码：

    <?php 
session_start();

//include_once "admin_check.php";

$dbh = mysqli_connect("host", "user", "password", "db");

if (!$dbh) {
    echo "Error: Unable to connect to MySQL." . PHP_EOL;
    echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;

    // this will tell you why the connection failed
    echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;

    exit;
}

echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($dbh) . PHP_EOL;

mysqli_close($dbh);
?>
<?php 
error_reporting(E_ALL);
ini_set('display_errors','1');
?>
<?php
if(isset($_POST['product_name'])){  
  $product_id = mysqli_real_escape_string($dbh,$_POST['id']);
  $product_name = mysqli_real_escape_string($dbh,$_POST['product_name']);
  $price = mysqli_real_escape_string($dbh,$_POST['price']);
  $details = mysqli_real_escape_string($dbh,$_POST['details']);
  $sql=mysqli_query($dbh,"SELECT id FROM products WHERE product_name='$product_name' LIMIT 1");
  $productMatch = mysqli_num_rows($sql);
  //if($productMatch>0){
  //echo 'Sorry you tried to place a duplicate Product Name into the system,<a href="product_list.php">click here</a>';
  //exit();
//  }
  $sql = mysqli_query($dbh,"INSERT INTO products(product_name, price, details,date_added)
  VALUES('$product_name','$price','$details',now())")or die(mysqli_error($dbh));
    $pid = mysqli_insert_id($dbh); 
    $newname = 'store'."$pid.jpg";
$url = "images/store";
$urlu = $url;
$basename="/var/tmp/$pid";

if ($_FILES["fileField"]["error"] > 0)
  {
  echo "Error: " . "$url" . $_FILES["fileField"]["error"] . "<br>";
  }
else
  {
   echo "Upload: " . "$url" . $_FILES["fileField"]["tmp_name"] . "<br>";
  echo "Upload: " . "$url" . $_FILES["fileField"]["name"] . "<br>";
  echo "Type: "  . "$url" . $_FILES["fileField"]["type"] . "<br>";  

  }
//move_uploaded_file("$urlu", $_FILES["fileField"]["tmp_name"]);
 // move_uploaded_file("$url", $_FILES["fileField"]["name"]);

     // echo "Stored in: " . "$urlu" . $_FILES["fileField"]["tmp_name"];

 move_uploaded_file($_FILES["fileField"]["tmp_name"],
      "$url" . "/" . $_FILES["fileField"]["name"]);
   echo "Stored in: " . "$url" . "/" .$_FILES["fileField"]["name"]; 
    if (move_uploaded_file("$url/" , $_FILES["fileField"]["name"])) {
      echo "File is valid, and was successfully uploaded.\n";  
 } else {
echo "Upload Failed";
print_r($_FILES);
print_r($_FILES["fileField"]);

        exit();
}

} 
?>
<?php 
$dbh = mysqli_connect("host","user","password", "db") or die ("could not connect to mysql"); 
$product_list = "";
$sql = mysqli_query($dbh,"SELECT * FROM products");
$productCount = mysqli_num_rows($sql);
if($productCount>0){
while($row = mysqli_fetch_array($sql)){
$id=$row['id'];
$product_name = $row['product_name'];
$details = $row['details'];
$price = $row['price'];
$date_added = strftime('%b %d,%Y',strtotime($row['date_added']));
$product_list.= "'$date_added'-'$id'-'$product_name' <a href=\"product_edit.php\">edit</a>.<a href=\"\">delete</a></br>";
