file upload php $_FILES undefined index error

Question

<?php

$name = $_FILES["file"]["name"];
//$size = $_FILES['file']['size']
//$type = $_FILES['file']['type']


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

$error = $_FILES['file']['error'];

if (isset ($name)) {
    if (!empty($name)) {

    $location = 'uploads/';

    if  (move_uploaded_file($tmp_name, $location.$name)){
        echo 'Uploaded';    
        }

        } else {
          echo 'please choose a file';
          }
    }
?>

<form action="upload.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="file"><br><br>
    <input type="submit" value="Submit">
</form>

i get an 'Notice: Undefined index' error message. The enctype is included in the form tag so i can't figure out what it is.. can anyone help me out??

Is your entire code inside one file, or are they split into two seperate files? — Funk Forty Niner

I agree. I was about to post an answer to that affect, but it's already been taken care of below. @voodoo417 — Funk Forty Niner

Actually, I changed my mind. I posted a working copy below. @voodoo417 — Funk Forty Niner

The first assignment throws an warning, if nothing is uploaded and the isset test is a little bit useless..

You can change your code as follows

<?php

if (isset($_FILES["file"]["name"])) {

    $name = $_FILES["file"]["name"];
    $tmp_name = $_FILES['file']['tmp_name'];
    $error = $_FILES['file']['error'];

    if (!empty($name)) {
        $location = 'uploads/';

        if  (move_uploaded_file($tmp_name, $location.$name)){
            echo 'Uploaded';
        }

    } else {
        echo 'please choose a file';
    }
}
?>

<form action="test.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="file"><br><br>
    <input type="submit" value="Submit">
</form>

The upload directory must exist and have write permissions (i.e. 755)

Resolved Undefined Index in php while uploading file
due to maximum file size limit
changes in php.ini

`max_execution_time` = 300  
`max_input_time` = 240  
`post_max_size` = 128M
`upload_max_filesize` = 128M

change according to your requirements

<form action="test.php" method="POST" enctype="multipart/form-data"> /* mistake here: change test.php to your source: upload.php */
    <input type="file" name="file"><br><br>
    <input type="submit" value="Submit">

If you're using your entire code as one file (which I suspect you are), then you need to do the following using a conditional statement, which I tested (and working) before posting.

Plus, make sure that your uploads folder has proper write permissions set and it exists.

<?php

if(isset($_POST['submit'])){
$name = $_FILES["file"]["name"];
//$size = $_FILES['file']['size']
//$type = $_FILES['file']['type']

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

if (isset ($name)) {
    if (!empty($name)) {

    $location = 'uploads/';

    if  (move_uploaded_file($tmp_name, $location.$name)){
        echo 'Uploaded';    
        }

        } else {
          echo 'please choose a file';
          }
    }
}
?>

<form action="" method="POST" enctype="multipart/form-data">
    <input type="file" name="file"><br><br>
    <input type="submit" name="submit" value="Submit">
</form>

Footnotes:

I added a conditional statement:

if(isset($_POST['submit']))

and I named the submit button: (to work in conjunction with the isset() conditional statement)

<input type="submit" name="submit" value="Submit">

N.B.: If you are in fact using your posted code as two seperate files, then you can simply copy the PHP in this answer, along with naming your present submit button set in a seperate HTML form as name="submit" (calling your form upload_form.htm for example) as I did shown above, yet retaining the action="upload.php" and naming the PHP upload handler file accordingly.

michAmir Over a year ago

but now i get this error: Warning: move_uploaded_file(uploads/testhoes.jpg): failed to open stream: No such file or directory in /var/www/upload.php on line 14. Warning: move_uploaded_file(): Unable to move '/tmp/phpnvksz8' to 'uploads/testhoes.jpg' in /var/www/upload.php on line 14

Does the folder exist and is it writeable? @user3221348 meaning, does it have the proper write permissions?

Funk Forty Niner Over a year ago

You haven't answered my question. @user3221348

michAmir Over a year ago

the tmp/ folder or the upload/ folder?

1. You hadn't mention name value in your submit button.
2. Use isset function.

<html>
<body>

<form action="" method="POST" enctype="multipart/form-data">
    <input type="file" name="file"><br><br>
    <input type="submit" value="Submit" name="submit">
</form>

</body>
</html>



<?php

if(isset($_POST['submit'])){

$name = $_FILES["file"]["name"];

echo $name;


//$size = $_FILES['file']['size']
//$type = $_FILES['file']['type']


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

$error = $_FILES['file']['error'];

if (isset ($name)) {
    if (!empty($name)) {

    $location = 'uploads/';

    if  (move_uploaded_file($tmp_name, $location.$name)){
        echo 'Uploaded';    
        }

        } else {
          echo 'please choose a file';
          }
    }
}       
?>

// Count total files
$countfiles = count($_FILES['event_Img']['name']);
for($i=0;$i<$countfiles;$i++){
    $filename = $_FILES['event_Img']['name'][$i];

    // Get extension
    $ext = end((explode(".", $filename)));
    move_uploaded_file($_FILES['event_Img']['tmp_name'][$i], "uploads/".$filename);
    $sqlBrand = 'INSERT INTO ot_event_images 
                SET 
                event_id=:event_id, 
                imagepath=:imagepath, 
                imagemimetype=:imagemimetype';
    $query2 = $conn->prepare($sqlBrand);
    $query2->bindParam(':event_id', $eventid);
    $query2->bindParam(':imagepath', $filename);
    $query2->bindParam(':imagemimetype', $ext);
    $status2 = $query2->execute();
}
if($status2)
{

    echo "File upload successfully";
}
else
{
    echo "error";
}
