	background: -webkit-linear-gradient(top,  #7abcff 0%,#60abf8 44%,#4096ee 100%);
	background: -o-linear-gradient(top,  #7abcff 0%,#60abf8 44%,#4096ee 100%);
	background: -ms-linear-gradient(top,  #7abcff 0%,#60abf8 44%,#4096ee 100%);

#percent { position:absolute; display:inline-block; top:3px; left:48%; }
.hide{display:none;}

Step 3 : create php upload file for create upload folder(directory) where to upload file in location

<?php  
if(isset($_FILES["file"]))
{ 
	 //You can validate the file type, size here. I left the code for you 
	 if ($_FILES["file"]["error"] > 0) 
	 { 
	   echo "Error: " . $_FILES["file"]["error"]; 
	 } 
	 else 
	 { 
	 
	  move_uploaded_file($_FILES["file"]["tmp_name"],'upload/'. $_FILES["file"]["name"]);   
	  echo "Uploaded File :".$_FILES["file"]["name"]; 
	 } 
} 

?>

Step 4: Create JavaScript function for  progress bar option.

$(document).ready(function()
{
	//Enable Upload button
	$('#file').change(function(){
		$('#submit').removeAttr('disabled');
	});
	//Show the progress bat after upload button hit
	$('#submit').change(function(){
		$('#progress').removeClass('hide');
	});
	
	//We can even provide options to ajaxForm to get callbacks like success,error, uploadProgress and beforeSend
    var options = {
	//beforeSend : this function called before form submission
    beforeSend: function()
    {
        $("#progress").show();
        //clear everything
        $("#bar").width('0%');
        $("#message").html("");
        $("#percent").html("0%");
    },
	//uploadProgress : this function called when the upload is in progress
    uploadProgress: function(event, position, total, percentComplete)
    {
        $("#bar").width(percentComplete+'%');
        $("#percent").html(percentComplete+'%');

    },
	//success : this function is called when the form upload is successful.
    success: function()
    {
        $("#bar").width('100%');
        $("#percent").html('100%');

    },
	//complete: this function is called when the form upload is completed.
    complete: function(response)
    {
        $("#message").html("<font color='green'>"+response.responseText+"</font>");
    },
    error: function()
    {
        $("#message").html("<font color='red'> ERROR: unable to upload files</font>");

    }

};
	////where myForm is the form id
     $("#myForm").ajaxForm(options);

});
