php not writing to txt file

[Strac72]

I am using a script I adapted from a tutorial to print the contents of a text box to a txt file. Basically, it's a really simple way of seeing who has logged in. I only have a handful of users.

 

The problem is, although the text file is being created in the proper folder, it isn't being written to and just remains blank.

 

<div align="center">

<table width="300" border="2" bordercolor="#FFFFFF" style="-moz-border-radius: 18px;

-webkit-border-radius: 18px;" height="120" cellpadding="0" cellspacing="0">

<tr>

<form name="form1" method="post" action="checklogin.php">

<td>

<table width="100%" border="0" cellpadding="3" cellspacing="1" background="images/loginbg.jpg"  style="-moz-border-radius: 15px;

-webkit-border-radius: 15px;">

<tr align="center">

<td colspan="3"><font color="#FFFFFF"><strong>Family Login </strong></font></td>

</tr>

<tr>

<td width="78"><font color="#000000">Username</font></td>

<td width="6">:</td>

<td width="294"><input name="myusername" type="text" id="myusername">

<?php

$myusername = $_POST['myusername'];

 

$data = "$myusername\n";

 

 

//open the file and choose the mode

$fh = fopen("logs/login.txt", "a");

 

fwrite($fh, $data);

 

fclose($fh);

 

?></td>

</tr>

<tr>

<td><font color="#000000">Password</font></td>

<td>:</td>

<td><input name="mypassword" type="password" id="mypassword"></td>

</tr>

<tr>

<td> </td>

<td> </td>

<td><input type="submit" name="Submit" value="Login">

</td>

</tr>

</table>

</td>

</form>

</tr>

</table>

</div>

 

I'm not sure what's going wrong but I'm guessing it's the placing of the php, or at least some of it.

I'd quite like to add the time they logged in as well. Any idea's anyone?

Actually, I've sussed the write part. I just needed to move the php to the checklogin.php page.

 

Would still appreciate help adding the time of login to that though!
