Cannot upload img to a folder - php

Question

Im using laravel. And the img wont upload to my public/imgs folder. It keeps saying Sorry, there was an error uploading your file.
// PHP CODE
$target_dir = "public/imgs/";
$target_file = $target_dir . basename($_FILES["img"]["name"]);
if (move_uploaded_file($_FILES["img"]["name"], $target_file)) {
echo "success";
}
else {
echo "Sorry, there was an error uploading your file.";
}
// HTML CODE
<form method="POST" action="/listings" enctype="multipart/form-data">
<input type="file" name="img">
</form>

Answer 1

First make sure the upload dir is existing and writable; then file_uploads is on in php.ini

Answer 2

Maybe you should change your original move_uploaded_file function to
move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)
See the diff between name and tmp_name

Answer 3

<form method="POST" action="/listings" enctype="multipart/form-data">
<input type="file" name="img">
</form>
HTML
$target_dir = "public/imgs/";
$target_file = $target_dir . basename($_FILES["img"]["name"]);
if ($_FILES['img']['error'] == 0) {
if (move_uploaded_file($_FILES['img']['tmp_name'], $target_file)) {
echo 'success';
} else {
echo 'upload failed<br>';
echo '<pre>';
echo 'tmp name: ';
print_r($_FILES['img']['tmp_name']);
echo "\n target: ".$target_file;
echo "\n\n";
print_r($_FILES['img']);
echo '</pre>';
}
} else {
echo 'upload failed: ' . $_FILES['img']['error'];
}
PHP
This code should work and show all data for debugging.
