Writting data to file

[seularts]

this is my code:

<?

$keyword=$_POST["key"];

$key=$keyword.', ';

$data = fopen('keywords.txt', "a");

fwrite($data,$key);

fclose($data);

?>

 

the problem is that it outputs:

Keyword, , Keyword, , Keyword,

I don't want double commas.

It looks like ure getting: keyword, empty post, keyword, empty post... U can throw an if(isset($_POST['keyword'])) before writting the file.

I think that the comma is witting itself again!

I used exactly the following code for a test:

 

<form name="form1" method="post" action="">
  <input name="key" type="text" id="key">
  <input type="submit" name="Submit" value="Submit">
</form>
<?php
if(isset($_POST['key'])){
$keyword=$_POST["key"];
$key=$keyword.', ';
$data = fopen('keywords.txt', "a");
fwrite($data,$key);
fclose($data);
}
?>

 

I entered "guilty" and submitted, "gear" and submitted and "guiltygear" and submitted and the output in "keywords.txt" is exactly: guilty, gear, guiltygear,

 

Cant seem to find a problem here!!
