How to rename uploaded file before saving it into a directory?
PhpMysqlFile UploadFile RenamePhp Problem Overview
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.

Solution 1 - Php
You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file
.
Instead of
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);
Use
$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);
Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.
Solution 2 - Php
You guess correctly. Read the manual page for move_uploaded_file
. Set the second parameter to whereever your want to save the file.
If it doesn't work, there is something wrong with your $fileName
. Please post your most recent code.
Solution 3 - Php
You can Try this,
$newfilename= date('dmYHis').str_replace(" ", "", basename($_FILES["file"]["name"]));
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);
Solution 4 - Php
/* create new name file */
$filename = uniqid() . "-" . time(); // 5dab1961e93a7-1571494241
$extension = pathinfo( $_FILES["file"]["name"], PATHINFO_EXTENSION ); // jpg
$basename = $filename . "." . $extension; // 5dab1961e93a7_1571494241.jpg
$source = $_FILES["file"]["tmp_name"];
$destination = "../img/imageDirectory/{$basename}";
/* move the file */
move_uploaded_file( $source, $destination );
echo "Stored in: {$destination}";
Solution 5 - Php
The move_uploaded_file
will return false if the file was not successfully moved you can put something into your code to alert you in a log if that happens, that should help you figure out why your having trouble renaming the file
