php - 将上传的文件移动到php的文件夹中

Question

我使用下面的代码将图像更新到表中，它可以很好地更新图像，但是在检索图像时，路径显示正确，但图像没有显示在页面中。请用上面的内容指导我

if(isset($_FILES['file'])){
    $errors= array();
    $file_name = $_FILES['file']['name'];
    $file_size =$_FILES['file']['size'];
    $file_tmp =$_FILES['file']['tmp_name'];
    $file_type=$_FILES['file']['type'];   
    $file_ext=strtolower(end(explode('.',$_FILES['file']['name'])));

    $expensions= array("jpg","png","gif");      
    if(in_array($file_ext,$expensions)=== false){
        $errors[]="extension not allowed, please choose a JPEG or PNG file.";
    }
    if($file_size > 2097152){
    $errors[]='File size must be excately 2 MB';
    }               
    if(empty($errors)==true){
        move_uploaded_file($file_tmp,"C:\wamp\www\Mr.bazaar\images\ ".$file_name);
        echo "Success";
    }else{
        print_r($errors);
    }
}


        $a=$_POST['pids'];
        echo $a;
        $b=$_FILES['file']['name'];
        echo $b;
        $qry1=mysql_query("update brand set image='$b' where brand='$a'");

        if($qry1)
        echo "<script>alert('Your image Sucessgully Uploaded.');</script>"; 
        else
        echo "<script>alert('try again');</script>";

我使用下面的代码在页面中显示图像，但它没有在页面中显示

$result = mysql_query("select b_id,brand,image from brand"); 

                while($row = mysql_fetch_array( $result )) {
                    // Print out the contents of each row into a table

                    echo '<tr>';

                    echo '<td>';
                    echo $row['brand'];
                    echo '</td><td>';
                    echo '<img height="30" width="60" src=../../images/';
                    echo $row['image'];
                    echo '>';

                    echo '</td>';


                }

您的上一个代码中没有对图像的引用。假设，循环应如下所示:

while ($row = mysql_fetch_array($result)) {
  $product = $row['brand'];
  $image = $row['image'];
  echo "<option value=\"$product\">$image</option>";
}
