php - Uploading Storing an Image inside a MySQL -


i trying upload , store image inside mysql, reason got broken photo when photo submitted . think there problem $image = $image->fetch_object(); when click on broken photo following error message: fatal error: call member function fetch_object() on non-object suggestion how fix 

<!doctype html> <html>     <head>         <meta http-equiv="content-type" content="text/html; charset=utf-8">         <title>upload image</title>     </head>     <body>         <form action="index.php" method="post" enctype="multipart/form-data">             file:              <input type="file" name='image'/> <input type="submit" value="submit">         </form>          <?php         //connect database         try{             $db = new mysqli('','','','');          }catch(exception $e){             echo $e->getmessage();         }          if(isset($_files['image'])){             $file = $_files['image']['tmp_name'];//['tmp_name'] temporary location          }          if(!isset($file)){             echo 'please select image';         }else{             $image = base64_encode(file_get_contents($_files['image']['tmp_name']));             $image_name = $_files['image']['name'];             $image_size = getimagesize($_files['image']['tmp_name']);               if($image_size == false){                 echo 'thats not image';             }else{                  $insert = $db->prepare("insert store values (?, ?, ?)");                 $insert->bind_param('bsi', $image, $image_name, $image_size);                 if(!$insert->execute()){                     echo "problem uploading file";                     }else{                     printf("%d row inserted.\n", $insert->affected_rows);                     echo $lastid = $db->insert_id;//returns last id inserted                      echo 'image uploaded.<p/> image:<p/><img src=get.php?id=$lastid>';                 }             }         }         ?>     </body> </html>

this updated code, dont error anymore image still broken getmessage(); }

$id = $_request['id'];//request because going use inside image tag  $image = $db->prepare("select * store id=?"); $image->bind_param('s',$id); if($image->execute()){         $image = $image->fetch(); }  $image = $image->image; header('content-type: image/jpeg');  echo $image;  ?>

sorry, missed main point.

the following code can't work:

$image = $db->query('select * store id=$id'); $image = $image->fetch_object();

$id in first statement not evaluated, because it's string in single quotes.

the cause broken images may use of addslashes() mask input, binary data. use prepared statement parameters , bind input data .

old answer

the php-manual says (http://www.php.net/manual/en/features.file-upload.post-method.php):

files will, default stored in server's default temporary directory, unless location has been given upload_tmp_dir directive in php.ini.

[...]

whatever logic, should either delete file temporary directory or move elsewhere.

[...]

you should move uploaded file move_uploaded_file(), before you're working it. , won't advocate storing of images in databases ...
