php upload file into the folder - php

Question

I am trying to upload multiple images into the folder using php . The code can print out the file names which means I get the files but now it does not upload them and I get no error : below is my code
<?php
$target = "image_uploads/";
if(isset($_FILES['FILE_NAME'])){
foreach($_FILES['FILE_NAME']['tmp_name']as $key => $error ){
print_r($key);
$file_upload = $key.$_FILES['FILE_NAME']['name'][$key];
#print image names
echo $file_upload.'</br>';
move_uploaded_file($file_upload,$target);
}
}
?>

Answer 1

In target you have to give the file name too. Please use the code below,
$target = "image_uploads/";
if(isset($_FILES['FILE_NAME'])){
foreach($_FILES['FILE_NAME']['tmp_name'] as $key => $error ){
print_r($key);
$file_upload = $key.$_FILES['FILE_NAME']['name'][$key];
print image names
echo $file_upload.'</br>';
move_uploaded_file($file_upload,$target.$_FILES['FILE_NAME']['name']);
}
}

Answer 2

I think the problem is in the foreach loop.
foreach ($_FILES['FILE_NAME']['tmp_name'] as $key => $val) {
// this loops through the tmp_name of $_FILES['FILE_NAME']
// which is a string
}
I think you meant something like:
foreach ($_FILES as $index => $fileArray) {
$tmpName = $fileArray['tmp_name'];
echo "File at key $index is temporarily uploaded at $tmpName";
}
The code above will loop through all uploaded files and print it's current filename.

Answer 3

It might happen that your target folder is not writable.
I also think, that the cause of which you're not getting errors is, that you have the following:
print_r($key);
Yous should have:
print_r($error);

There can be multiple reasons for this :
The target folder must exist before trying to move the file from temp location to the target and must also be writable
the move_uploaded_file takes the second argument as the file name followed by the directory name, so it can be something like : target folder/user.file.name.ext
If you are uploading multiple files, then the $_FILES must be accessed as shown in the link : http://php.net/manual/en/features.file-upload.multiple.php
