Undefined index: on uploading an image into database from php

Question

Sorry for that question, but I tried everything and i can't solve my problem.

I'm trying to add an image to the database from a form in php and then show the image on the page.

However I am with an error I can't solve.

The error is this: Notice: Undefined index: image in C: \ xampp \ htdocs \ test \ index2.php on line 18

Does anyone could help me please?

Thanks everyone.

-----index.php-----------

    <html>
    <head>
        <title>Upload an image</title>
    </head>   
    <body>

        <form action="index2.php" method="POST" enctype="multipart/form-data">
             File:
            <input type="file" name="image"> <input type="submit" value="Upload">

        </form>

        <?php
if (isset($_FILES['image'])) {
mysql_connect("localhost", "root", "*****") or die (mysql_error());
mysql_select_db('database') or die (mysql_error());

$file = $_FILES['image']['tmp_name'];


if (!isset($file)) 
    echo "Please select an image";
else{
   echo $image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
   $image_name = $_FILES['image']['tmp_name'];
   $image_size = getimagesize($_FILES['image']['tmp_name']);

   if($image_size==FALSE)
       echo "That's not an image";
   else{
            if(!$insert = mysql_query("INSERT INTO table_image(name_image, image) VALUES ('Test','$image' )"))
            echo"Problem uploading image.";
            else
            {
                $lastid = mysql_insert_id();
            echo"Image uploaded.<p />Your Image: <p /><img src=get.php?id=$lastid>";
            }

        }
}
}
?>

------get.php-----

   <?php

mysql_connect("localhost", "root", "*****") or die (mysql_error());
mysql_select_db('database') or die (mysql_error());

$id = addslashes($_REQUEST['id']);

$image = mysql_query("select * from table_image where id=$id");
$image = mysql_fetch_assoc($image);
$image = $image['image'];

header("Content-type: image/jpeg");
echo $image;


?>

enter image description here

Line 18: $file = $_FILES['image']['tmp_name'];

What's going on?

Well the error, is just a notice.. Meaning there isn't a value for the key you are trying to call.. — Naruto

Change if (isset($_POST['image'])) to if (isset($_FILES['image'])) — Funk Forty Niner

You forgot the 't' here.

enctype="mulipart/form-data"

so

enctype="multipart/form-data"

You're also trying to check for isset($_POST['image']) which should be isset($_FILES['image'])

Good catch. This if (isset($_POST['image'])) would also be an issue.

Thanks for reply. I tried what you said, and then give me that error "Problem uploading image."

You're trying to insert an uploaded file into a column. That won't work. You have to move you're file to a directory on the server with move_uploaded_file

...or set column as blob.

@Fred-ii- True but I try to avoid it. Actually I never use it.

apart from typo fix of mulipart/form-data to multipart/form-data You need to validate/check it before accessing

if (!empty($_FILES['image']['name'])) {
    $file = $_FILES['image']['tmp_name'];
}
