PHP provides built-in function move_uploaded_file() for uploading files to a directory. This function requires two parameters, those are the source file and the destination for the moved file.
This function will check if the uploaded file is posted via the HTTP POST method to protect the file data. The is_uploaded_file is used to check if the file is uploaded via the HTTP POST method.
In this tutorial, we are going to upload files using an HTML form. This form should contain the attributes as method=’post’ and enctype=’multipart/form-data’ to support file upload. It helps to bundle the form data and the binary data to post it to the server-side PHP file.
In PHP code, it will read the uploaded file information by using $_FILES superglobal. It will check that the $_FILES array is not empty and the uploaded file is posted via the HTTP POST method and then executes the file upload script. Refer to my earlier article for PHP AJAX image upload.
Create HTML form
The code shows the form with method=’post’ and enctype=’multipart/form-data’ attributes to upload files. It contains a file type input field to select the file to be uploaded. On submitting this form, the form-data and the file binary-data will be bundled and posted to the PHP file.
<form action="" enctype="multipart/form-data" method="POST"
name="frm_user_file">
<input type="file" name="myfile" /> <input type="submit" name="submit"
value="Upload" />
</form>
PHP File Upload Code
This PHP code validates that the uploaded file is not empty and is posted via the HTTP_POST method. Then, it specifies the source and destination file path to the move_uploaded_file() function to move the source file to the target as specified.
<?php
$targetDir = "uploads";
if (isset($_FILES['myfile']) && is_array($_FILES)) {
if (is_uploaded_file($_FILES['myfile']['tmp_name'])) {
if (move_uploaded_file($_FILES['myfile']['tmp_name'], "$targetDir/" . $_FILES['myfile']['name'])) {
echo "File uploaded successfully";
}
}
}
?>
hello vincy. thank you for the code. i tried to use this code to create a system where users can upload their pics but it only brings out a blank page with no error of success massage i added to it. i also ensured that i edited the is_uloaded_file to is_uploaded_file.
i also did not see any uploaded image in my target directory.
How may i go about making it work for my project as i intend to be refering to each uploaded pic in different users session
Hi Akinsola,
I corrected the code sample with is_uploaded_file().
And, added source code zip to download. Try with that. Hope, it would be helpful.
Thanks Vincy.
