Example
<input type="file" name="fileSubmission">
File inputs allow users to select a file from their local filesystem for use with the current page. If used in conjunction with a form element, they can be used to allow users to upload files to a server (for more info see Uploading Files).
The following example allows users to use the file input to select a file from their filesystem and upload that file to a script on the server named upload_file.php.
<form action="upload_file.php" method="post" enctype="multipart/form-data">
Select file to upload:
<input type="file" name="fileSubmission" id="fileSubmission">
<input type="submit" value="Upload your file" name="submit">
</form>
Multiple files
Adding the multiple attribute the user will be able to select more than one file:
<input type="file" name="fileSubmission" id="fileSubmission" multiple>
Accept Files
Accept attribute specifies the types of files that user can select. E.g. .png, .gif, .jpeg.
<input type="file" name="fileSubmission" accept="image/x-png,image/gif,image/jpeg" />
