Warning: Invalid argument supplied for foreach() in /home/...

Recommended Posts

I want my visitors to be able to upload multiple image files. the script I'm using is:

<form action="" method="post" enctype="multipart/form-data">

<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="submit" value="Send" />
</p>
</form>
<?php
foreach ($_FILES["pictures"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$tmp_name = $_FILES["pictures"]["tmp_name"][$key];
$name = $_FILES["pictures"]["name"][$key];
move_uploaded_file($tmp_name, "data/$name");
}
}
?>

When I goto the form this error is displayed at the bottom:
[font=Verdana][color=red]Warning: Invalid argument supplied for foreach() in /home/...[/color][/font] 
using this script the files do upload successfuly and after uploading the files just once the error then goes away.
what do I need to do to rid the error when you first goto the page?

<form action="" method="post" enctype="multipart/form-data">

<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="submit" value="Send" />
</p>
</form>
<?php
foreach ($_FILES["pictures"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$tmp_name = $_FILES["pictures"]["tmp_name"][$key];
$name = $_FILES["pictures"]["name"][$key];
move_uploaded_file($tmp_name, "data/$name");
}
}

?>
