Question

嗨，这是我的脚本，当有人上传图像时，它会将数据保存到数据库中，并且还会创建一个标题填写的页面。请参阅PHP脚本中的$ template，它是生成的页面，它是空的，但我想在上传图像时在此页面中显示图像。

此脚本可以执行的操作：当有人上传图片时它会自动创建一个页面，其中包含在标题部分填写的URL 它使用这些信息ID，用户名，链接，类型，大小，名称

将数据保存到表save_data中的数据库中

我想要什么当它创建页面时，它会显示上传的图像

使用图片创建的PHP上传脚本：

<?php
    if(!isset($_COOKIE['loggedin'])){
        header("location:index.php");
    }

session_start();

if(!isset($_SESSION['user'])){

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

?>

<?php
    include("connection.php");
$current_page_URL =(isset($_SERVER["HTTPS"]) && $_SERVER["HTTPS"]==”on”) ? “https://” : “http://”;

$current_page_URL = $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];

$allowed_filetypes = array('.jpg','.JPG','.jpeg','.png','.gif','.JPEG','.PNG','.GIF');
$max_filesize = 10485760;
$upload_path = 'uploads/';

$filename = $_FILES['image_file']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

if(!in_array($ext,$allowed_filetypes))
  die('The file you attempted to upload is not allowed.');

function bytesToSize1024($bytes, $precision = 2) {
    $unit = array('B','KB','MB');
    return @round($bytes / pow(1024, ($i = floor(log($bytes, 1024)))), $precision).' '.$unit[$i];
}

$sFileName = $_FILES['image_file']['name'];
$sFileType = $_FILES['image_file']['type'];
$sFileSize = bytesToSize1024($_FILES['image_file']['size'], 1);




    if (file_exists("uploads/" . $_FILES["image_file"]["name"]))
      {
      echo $_FILES["image_file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["image_file"]["tmp_name"],
      "uploads/" . $_FILES["image_file"]["name"]);
      echo "Stored in: ".$_SERVER["SERVER_NAME"]. "/uploads/" . $_FILES["image_file"]["name"];

      }
      $savefile = $_SERVER["SERVER_NAME"]. "/uploads/" . $_FILES["image_file"]["name"];

      $insert_query = "insert into save_data (username, Name, Type, size, link) values ('".$_SESSION['user']."','$sFileName','$sFileType','$sFileSize','$savefile')";

    if(mysql_query($insert_query)){

    echo "<script>alert('Successfully added to DB')</script>";



  //if the notice is set then display it
if(isset($notice)){echo $notice;} 
}}

// PAGE的模板

$template = <<<EOD
<?php

<html>
<body>

</body>
</html>
EOD;

//页面创建脚本

//handle the posted form
if(isset($_POST['title'])){
    //replace the areas of the template with the posted values
    $page = str_replace('<!--TITLE-->',htmlentities($_POST['title']),$template);;
    //create a name for the new page
    $pagename =($_POST['title']).'.php';

    //db connect & select
    $db=mysql_connect('localhost','root','123');
    mysql_select_db('user');

    //check if page already exists
    $result = mysql_query('SELECT pagename from pages WHERE url="'.mysql_real_escape_string($pagename).'"');
    if(mysql_num_rows($result)>=1){
        $notice = '<p>Page already created <b>./pages/'.$pagename.'</b></p>';
    }else{
        //inset new page into db
        mysql_query('INSERT into pages (`id`,`title`,`comment`,`url`)VALUES("",
        "'.mysql_real_escape_string(htmlentities($_POST['title'])).'",
        "'.$pagename.'")');
        //put the created content to file
        file_put_contents('./pages/'.$pagename,$page);
        //make a notice to show the user
        $notice = '<p>New Page created <b>./pages/'.$pagename.'</b></p>';
    }
}
  ?>
