So, how we do we handle file upload in php. Now its relatively easy handle file uploads in php. For the purpose of this tutorials You can see screenshot 1 script file name upload.php and directory name uploads/ folder. We will work with upload.php. Now the purpose of this videos its just simply how we take a file allow the user to select file from the computer and then send it to specific directory. Here we are not not looking to the security for uploading of the files. So, This codes are not safe to use at web-server because in actual facts the user will be upload any file.

$tmp_name = $_FILES['file']['tmp_name'];



if (isset($name)) {

if(!empty($name)) {

echo 'OK.';

}else {

echo 'Please Choose a file.';

}

}



?>

We will start with create form with form action upload.php because out php script is in same file. method is going to be POST remember we are sending large amount of data so method be Post. There is one addition attribute you need to apply in this form tag encrypt this is a way the data in form encoded when its send we need to supply this multipart/form-data So this is basically allow us to process the form and enable file upload we are sending alot much amount data and this is  encrypt this just tell us when we process on it it tells how we gonna encoded the data. So, Now we allow the user to upload the file we use input type tag file which will create browse button with name called file Then we create Submit Button to it.

In this article we are not including form security in another article we will only allow .jpg file to be uploaded. When the file is upload with php script we will grape file name, size of file, temporary location of the file. 

<?php

$name = $_FILES['file']['name'];

$size = $_FILES['file']['size'];

$type = $_FILES['file']['type'];



$tmp_name = $_FILES['file']['tmp_name'];



if (isset($name)) {

if(!empty($name)) {

echo 'OK.';

}else {

echo 'Please Choose a file.';

}
}



?>

In piece of php code we will grape the file name $name = $_FILES['file']['name']; This will show us the file name, $size = $_FILES['file']['size']; This will show us the file size, Then $type = $_FILES['file']['type']; This will show us the file type, $tmp_name = $_FILES['file']['tmp_name']; This will show the temporize location the file had been uploaded to the server. $error = $_FILES['file']['error']; This will show any error in uploading the files to the server.

Then i will check whether the file is uploaded we can access all information of file which is uploaded to the server but in this example i will only just check whether file is uploaded or not so will check with isset function. You can see output screenshot if file is not choose it shows message to the user please choose a file and if file is uploaded to the server you can see the message ok.

Code for Uploading File to the Directory 

<?php

$name = $_FILES['file']['name'];

$size = $_FILES['file']['size'];

$type = $_FILES['file']['type'];



$tmp_name = $_FILES['file']['tmp_name'];



if (isset($name)) {

if(!empty($name)) {





$location = 'uploads/';



if(move_uploaded_file($tmp_name, $location.$name)) {

echo 'Uploaded!';

}else {

echo 'Please Choose a file.';

}

}



?>



<form action = "upload.php" method="POST" enctype="multipart/form-data">

<input type="file" name="file"><br><br>

<input type="submit" value="Submit">

</form>

In this example we are uploading file to temporarily location to particular directory which we had uploads folder as you can see screenshots6 File is saved in uploads folder. In screenshot7 you can see the file url it is saved in uploads folder. In this way we can successfully uploaded a file. We used move_uploaded_file function with passing two parameters $tmp_name is variable in which temporarily file location and the $location where we want to move the file with $name variable which contain the name of the file with extension of the file.
