php - 使用uploadify上传文件 [英] php - file uploads using uploadify

问题描述

我在使用uploadify时遇到问题。每当我在$ post_id中使用一个字符串，uploadify只会上传一个文件，当我选择了3个文件上传。
但是当我为$ post_id指定一个不存在的值时，例如不存在的$ _SESSION ['something']会话变量。它将所有三个文件插入到数据库中。我在想这可能是$ post_id的数据结构的错误。

  if（！empty（$ _ FILES））{
 $ post_id ='aa'; 
 $ name2 = mysql_real_escape_string（$ _ FILES ['Filedata'] ['name']）; 
 $ mime2 = mysql_real_escape_string（$ _ FILES ['Filedata'] ['type']）; 
 $ data2 = mysql_real_escape_string（file_get_contents（$ _ FILES ['Filedata'] ['tmp_name']））; 
 $ size2 = intval（$ _ FILES ['Filedata'] ['size']）; 
 
 
 $ b $ db-> query（INSERT INTO tbl_files SET post_id ='$ post_id'，filename ='$ name2'，file_data ='$ data2'，mime_type_id = '$ MIME2'）; 
 
 
 
} 
  

其余的数据，似乎他们只存储简单的字符串。所以$ post_id字符串也应该工作，

  echo $ _FILES ['Filedata'] ['name']; 
  

解决方案

  $ tblQry ='INSERT INTO tbl_files'; 
 $ tblQry。='SET 
 post_id ='。$ _ SESSION ['post_id']。'，
 filename ='。$ name2。'，
 file_data ='。$ data2。'，
 mime_type_id ='。$ mime2。''; 
 $ db-> query（$ tblQry）; 
  

I'm having problems with uploadify. Whenever I use a string in the $post_id, uploadify only uploads a single file when I've selected 3 files for upload. But when I specify a non-existing value for $post_id such as a session variable that doesn't exist $_SESSION['something']. It inserts all three of the files into the database. I'm thinking that this might be an error on the data structure of $post_id.

 if(!empty($_FILES)){
            $post_id = 'aa';
            $name2 = mysql_real_escape_string($_FILES['Filedata']['name']);
            $mime2 = mysql_real_escape_string($_FILES['Filedata']['type']);
            $data2 = mysql_real_escape_string(file_get_contents($_FILES['Filedata']['tmp_name']));
            $size2 = intval($_FILES['Filedata']['size']);



            $db->query("INSERT INTO tbl_files SET post_id='$post_id', filename='$name2', file_data='$data2', mime_type_id='$mime2'");



    }

I tried to echo the rest of the data and it seems like they're only storing plain strings. So $post_id string should also work,

echo $_FILES['Filedata']['name'];

解决方案

Try this it should work as you expected

 $tblQry = 'INSERT INTO tbl_files ';
 $tblQry .= 'SET         
        post_id                 = "' .$_SESSION['post_id'] . '",
        filename                = "' .$name2. '",
        file_data               = "' .$data2.'",
        mime_type_id            = "' .$mime2.'"';
  $db->query($tblQry);
