Image Uploading to mysql database using PHP

Question

I'm trying to upload image to mysql table. When image selected it's working fine. But without selecting image it's display error message. How can i fix it?

Warning: file_get_contents(): Filename cannot be empty in C:\wamp\www\firstdialnew\firstdial\adhandler.php on line 23

$stype=$_POST['stype'];
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
$image_name = addslashes($_FILES['image']['name']);

if($stype="")
{
echo "Please fill all the details";
}else{
$sql=mysql_query("INSERT INTO ads
                            (sid,stype,image,image_name)
                            VALUES(NULL,'$stype','$image','$image_name')");
echo "Details Successfully send";
}

The message is clear,you have nothing in $_FILES,show the part where you upload the file — Mihai

have you tried dumping the contents of your $_FILES array - it seems you have nothing in the array thats why you are getting that message — Halfpint

It's a better idea to keep the image in server and store the path in database. — Mahasish

There are several errors. if case is incorrect; use of deprecated mysql_* functions; use of $_FILES's tmp_name; also, you didn't move your file from temp folder to final path. — Raptor

And you shouldn't save the image contents in MySQL; save the path only. — Raptor

you need to check/validate that image is upload or not try something like that

if (!empty($_FILES['image']['name'])) {
   $image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
   $image_name = addslashes($_FILES['image']['name']);
}else{
   $image = '';
   $image_name = '';
}

No. You shouldn't use file_get_contents() on $_FILES.

Follow my experience, you should save image into folder (ex : public/upload/images/image_name.png) AND save image path into database. That is simple and database's size is not large

Although your suggestion is perfectly correct, this is not an answer (a comment instead).

You are not checking for $_FILES try this

$stype=$_POST['stype'];
if(isset($_FILES['image']) ) {
    $image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
    $image_name = addslashes($_FILES['image']['name']);
}else{
    $image = '';
    $image_name = '';
}

I will suggest you to upload file in a folder and store the file name in mysql table.

Here is how you can do that

$file_path = "uploads/";

if(isset($_FILES['image']) ) {
   $file_name  = basename( $_FILES['uploaded_file']['name']);
   $file_path = $file_path . $file_name;

   //You should validate the image before upload
   move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path);
 }else{
    $image = '';
    $image_name = '';
}

//now store file name in db
$sql=mysql_query("INSERT INTO ads
                        (sid,stype,image,image_name)
                        VALUES(NULL,'$stype','$file_name','$image_name')");

@RamSharma this is the suggested use of $_FILES. file_get_contents() is unnecessary & move_uploaded_file() should be used.

Did you add :

    <form method="POST" enctype="multipart/form-data">

Into your form (enctype="multipart/form-data")

I feel he is adding this because he is able to save the image but getting issue if image is not selected

try this :

 $stype=$_POST['stype'];
     $image_name ='';
     $image='';
     if(!empty($_FILES['image'])) {
     $image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
     $image_name = addslashes($_FILES['image']['name']);
      } 
      if($stype="")
      {
      echo "Please fill all the details";
      }else{
       $sql=mysql_query("INSERT INTO ads
                        (sid,stype,image,image_name)
                        VALUES(NULL,'$stype','$image','$image_name')");
         echo "Details Successfully send";
       }
