                            VALUES(NULL,'$stype','$image','$image_name')");
echo "Details Successfully send";

Answer 1

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 = '';
}

Answer 2

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')");

Answer 3

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

Answer 4

Did you add :

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

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

Answer 5

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";
       }
