Hello,

 

Notice is not an error.

 

Try to replace:

$addBalance = $_POST['addBalance'];

with:

if(isset($_POST['addBalance'])){
  $addBalance = $_POST['addBalance'];
} else {
  $addBalance = 0;
}

Your code is going to put up the form, and then immediately go into the PHP code, so $_POST elements such as addBalance will not be defined (nothing has been received from the form). Your code needs to check whether it's supposed to put up the form, OR process the data returned by the form, but not both at the same time. Generally you can do this by checking whether something like $_POST['addBalance'] is set or not (isset() function).

Ok...

 

One more question about PHP

 

 

 

 

print "<td align='right'><A href='editFeeds.php?$filename'>Editar</a></td>";

 

On explorer address bar appears

 

http://127.0.0.1/admin/editFeeds.php?xpto1.txt

 

ou

 

http://127.0.0.1/admin/editFeeds.php?kartunes1.txt

 

 

But when i jump to the new page 'editFeeds.php' the string $results is empty...

 

How can i build a Hyperlink to have the string $filename with value xpto1.txt or kartunes1.txt on the new page ''editFeeds.php'????

 

 

Can anyone help?????

 

 

 

alguém pode ajudar????

Change

print "<td align='right'><A href='editFeeds.php?$filename'>Editar</a></td>";

to

print "<td align='right'><A href='editFeeds.php?results=$filename'>Editar</a></td>";

 

and in editFeeds.php, add near the top

$results = $_REQUEST['results'];

 

Before you do any more coding on your own, I suggest that you 1) read some "teach yourself PHP" books, and 2) study some code from a working site. It's quite apparent that you know nothing about how PHP works, and you're just blindly trying this and that.
