<?php echo getenv("username"); ?>

By using javascript (actually VBscript) you can get the visitor’s windows username. But there are also limitations. It only works on IE.

<script language="VBscript">
Dim X
set X = createobject("WSCRIPT.Network")
dim U
U=x.UserName
MsgBox "username: " & U
</script>
<script language="Javascript">
var a = U;
alert("Hello, " + a.toString());
</script>

This code will show you the current windows username. But won’t work if run from http://. Open the page from your computer with IE and it’ll work, otherwise not.

Actually it is not possible to get the windows username of your website visitors as it is a security issue. So don’t waste your time if you are trying to do that.

I have written a very simple PHP function for this:

<?php
function genquery($table, $data, $mode = 'insert into', $condition = '', $raw = '') {
	$res = mysql_query("select * from $table limit 1");

	$field_arr = array();
	for($i=0; $i < mysql_num_fields($res); $i++) {
		$field_arr[] = mysql_field_name($res, $i);
	}
	mysql_free_result($res);

	$qstr = $mode." ".$table." set ";
	$arr = array();
	foreach($data as $k => $v) {
		if(!in_array($k, $field_arr)) continue;
		$arr[] = $k." = '".$v."'";
	}
	$qstr .= implode(', ', $arr);

	$qstr .= ' ' . $raw;

	if($mode == 'update' && $condition != ''){
		$qstr .= ' where ' . $condition;
	}
	return $qstr;
}
?>

You must follow a simple way for using this function. The name of the input fields in the form should be same as the fields in the table of your database. I assume your form will be submitted in POST format. In fact a form with many fields is always submitted in post method.

Here is how to use this function:

<?php
include("qfn.php");
if(isset($_POST['submit'])){  // if the form is submitted

$q = genquery("tableName", $_POST, "INSERT INTO", '', '');
mysql_query($q);
}
?>

For updating use:

$q = genquery("tableName", $_POST, "UPDATE", " id = '$_SESSION[id]' ", '');
// the 4th parameter is the condition for update. Use your own condition.

You can use more than one condition like:

$q = genquery("tableName", $_POST, "UPDATE", " id = '$_SESSION[id]' AND uid = '$_SESSION[uid]' ", '');

The 5th parameter is for raw values like

"entry_date = CURDATE(), status = '1' "

You can use the 5th parameter both for INSERT and UPDATE query. But the 4th parameter is only for UPDATE query.

Hope this will help you a lot and save your time & energy.

For my own need I added 2 extra fields. They are sent to server via POST method along with the FILES. One thing I’ve noticed, it can upload file faster than normal file uploading method. Cos, the file is encoded first via the flash uploader and somehow it is faster than normal.

And the great advantage is you can select multiple files during browsing by pressing Ctlr + A or select your files by dragging mouse. By using html <input type=”file” /> you can only select one file at a time which is really so boaring and life-taking when you want to upload hundreds of images.

Here is the online demo. The files are not being saved on my server for my own security!

Download it here completely free in a single zip file!

Modify the index_files/config.js file line no 49,
var _site_root = ‘your script location’;
It won’t work for you until you change _site_root

I have no problem if you use it for your own use. But I do not actually want anyone to put the files/zip on their own site to drive the traffics away from our blog.

If you need any support for modifying or setting it up or any bug report please contact me directly at adnan.eee@gmail.com

Thanks
Have a pain-less uploading experience!
