mysql - PHP - file not sending to database error -

i allow users submit files database on website. every time file submitted, these error messages

( ! ) warning: file_get_contents() expects parameter 1 valid path, array given in c:\wamp64\www\mt\developerupload.php on line 8  ( ! ) warning: trim() expects parameter 1 string, array given in c:\wamp64\www\mt\developerupload.php on line 9 

but told "file_get_contents" way send file contents database. without "file_get_contents" sends it, gives me error messages , not sure why. want is, submit file using "file_get_contents" later on can display content on users page. here code

php

$query = "insert pack_screenshots(pack_id, file_name, file_tmp)values(:packid, :file_name, :file_tmp)"; $stmtfileupload = $handler->prepare($query); $errors = array();

         foreach($_files['file']['tmp_name'] $key => $error){               if ($error != upload_err_ok) {                 $errors[] = $_files['file']['name'][$key] . ' not uploaded.';                 continue;             }               $file_tmp = file_get_contents($_files['file']['tmp_name']);             $file_name = addslashes(trim($_files['file']['name']));              try{                   $stmtfileupload->bindparam(':packid', $packid, pdo::param_str);                  $stmtfileupload->bindparam(':file_name', $file_name, pdo::param_str);                  $stmtfileupload->bindparam(':file_tmp', $file_tmp, pdo::param_str);                  $stmtfileupload->execute();                   $dir = "devfiles";                   if(is_dir($dir)==false){                       mkdir($dir, 0700);                  }                   if(is_file($dir.'/'.$file_name)==false){                       move_uploaded_file($file_tmp,$dir.'/'.$file_name);                   }else{                        $_session['invalid'] = true;                       header("location: developer_invalid.php");                       exit;                  }                   $_session['thankyou'] = true;                  header("location: developerupload_thankyou.php");                  exit;              }catch(pdoexception $e){                   $errors[] = $file_name . 'not saved in db.';                  echo $e->getmessage();              }          } 

your problem have no keys associated 2 lines giving error (and elsewhere in code), therefore arrays (as not selecting specific key).

you need associate keys $_files array.

$file_tmp = file_get_contents($_files['file']['tmp_name'][$key]); $file_name = addslashes(trim($_files['file']['name'][$key]));
