No filename when uploading a file - php

Question

I found a code online for uploading a file(a picture) from a form. It works great, but I want it to write the file name into a table, like the rest of the data from the form. I'm using this code
?php
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file1"]["name"]);
$extension = end($temp);
if ((($_FILES["file1"]["type"] == "image/gif")
|| ($_FILES["file1"]["type"] == "image/jpeg")
|| ($_FILES["file1"]["type"] == "image/jpg")
|| ($_FILES["file1"]["type"] == "image/pjpeg")
|| ($_FILES["file1"]["type"] == "image/x-png")
|| ($_FILES["file1"]["type"] == "image/png"))
&& in_array($extension, $allowedExts)) {
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file1"]["error"] . "<br>";
} else {
echo "Upload: " . $_FILES["file1"]["name"] . "<br>";
echo "Type: " . $_FILES["file1"]["type"] . "<br>";
echo "Size: " . ($_FILES["file1"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file1"]["tmp_name"] . "<br>";
if (file_exists("upload/" . $_FILES["file1"]["name"])) {
echo $_FILES["file1"]["name"] . " already exists. ";
} else {
copy($_FILES["file1"]["tmp_name"],
"upload/" . $_FILES["file1"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file1"]["tmp_name"];
}
}
} else {
echo "Invalid file";
}
?>
