Uploading files with PHP - php

Question

I am using a form for users to upload files to my website. I want to allow them to upload multiple photos at once, so I am using the HTML5 "multiple" attribute.
My HTML:
<form method="post" action="save.php">
<input type="file" name="uploads[]" multiple="multiple" />
<input type="submit" name="submit" value="submit"/>
</form>
save.php:
<?php
foreach ($_FILES['uploads']['name'] as $file) {
echo $file . "<br/>";
$file= time() . $_FILES['uploads']['name'];
$target= UPLOADPATH . $file;
move_uploaded_file($_FILES['uploads']['tmp_name'], $target)
or die('error with query 2');
}
But, for some reason when I run the script, I get an error saying undefined index: uploads. And an error saying that I have an invalid argument supplied for foreach(). What could I be dong wrong?
Thanks
UPDATE
Okay, setting the enctype="mulitpart/form-data" worked. Now, I am having trouble with moving the file. I am getting the error move_uploaded_file() expects parameter 1 to be string, array given. What am I doing wrong here?
Thanks again

Answer 1

You need the proper enctype to be able to upload files.
<form method="post" enctype="multipart/form-data" action="save.php">

Answer 2

try this html code: <form method="post" action="save.php" enctype="multipart/form-data">
Then in PHP:
if(isset($_FILES['uploads'])){
foreach ($_FILES['uploads']['name'] as $file) {
echo $file . "<br/>";
$file= time() . $_FILES['uploads']['name'];
$target= UPLOADPATH . $file;
move_uploaded_file($_FILES['uploads']['tmp_name'], $target)
or die('error with query 2');
}
} else {
echo 'some error message!';
}

Answer 3

In order to upload files in the first place, you need enctype="multipart/form-data" on your <form> tag.
But, when you upload multiple files, every key in $_FILES['uploads'] is an array (just like $_FILES['uploads']['name']).
You need to get the array key when looping, so you can process each file. See the docs for move_uploaded_file for more deatils.
<?php
foreach ($_FILES['uploads']['name'] as $key=>$file) {
echo $file."<br/>";
$file = time().$file;
$target = UPLOADPATH.$file;
move_uploaded_file($_FILES['uploads']['tmp_name'][$key], $target)
or die('error with query 2');
}

index.html
<form method="post" action="save.php" enctype="multipart/form-data">
<input type="file" name="uploads[]" multiple="multiple" />
<input type="submit" name="submit" value="Upload Image"/>
</form>
save.php
<?php
$file_dir = "uploads";
if (isset($_POST["submit"])) {
for ($x = 0; $x < count($_FILES['uploads']['name']); $x++) {
$file_name = time() . $_FILES['uploads']['name'][$x];
$file_tmp = $_FILES['uploads']['tmp_name'][$x];
/* location file save */
$file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name;
if (move_uploaded_file($file_tmp, $file_target)) {
echo "{$file_name} has been uploaded. <br />";
} else {
echo "Sorry, there was an error uploading {$file_name}.";
}
}
}
?>
