        $target_path = $target_path .$basename;//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array       

        if (($_FILES["file"]["size"][$i] < (1024*1024)) //Approx. 100kb files can be uploaded.
        && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';

                $filepath = rtrim($file_name_all, '*');  
                //echo"<img src=".$filepath."   >";          

                /*************************************************/
            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
    $qry="INSERT INTO `eb_re_about_us`(`er_abt_us_id`, `er_cli_id`, `er_cli_abt_info`, `er_cli_abt_img`) VALUES (NULL,'$b1','$b5','$filepath')";


    $res = mysql_query($qry,$conn); 
    if($res)
        echo "<br/><br/>Client contact Person Information Details Saved successfully";
        //header("location: nextaddclient.php");
        //exit();
    else
        echo "<br/><br/>Client contact Person Information Details not saved successfully";

}
?>
