Below is the code I used in order to upload files into a directory. It works fine. My main question is:
move_uploaded_file() is the one that saves the uploaded file into the directory, and it is also my guess that move_uploaded_file() is the one that sets the name for it.
How could I change the name of my file to a random number?
I have tried to do so below:
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/jpg") || ($_FILES["file"]["type"] == "image/pjpeg") || ($_FILES["file"]["type"] == "image/x-png") || ($_FILES["file"]["type"] == "image/png")) && ($_FILES["file"]["size"] < 100000) && in_array($extension, $allowedExts)) {
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
} else {
$fileName = $temp[0] . "." . $temp[1];
$temp[0] = rand(0, 3000); //Set to random number
$fileName;
if (file_exists("../img/imageDirectory/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " already exists. ";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);
echo "Stored in: " . "../img/imageDirectory/" . $_FILES["file"]["name"];
}
}
} else {
echo "Invalid file";
}
I tried changing variables such as the $_FILES["file"]["name"] and replacing it with the $fileName; variable so that the new name can be stored.
