Hi,

Below is the error I get (using PHP Version 4.4.1):

PHP Code:

Warning: Wrong parameter count for trim() in /home/public_html/review/functions.php on line 19



Warning: Wrong parameter count for nl2br() in /home/public_html/review/functions.php on line 20



Warning: htmlentities() expects at least 1 parameter, 0 given in /home/public_html/review/functions.php on line 21 

Here are lines 19-21:

PHP Code:

function clean($v) { 

  $v = stripslashes(trim($v)); 

  $v = nl2br($v); 

  $v = htmlentities($v); 

  return $v; 

} 

Here is the code calling the function:

PHP Code:

$username = clean($_POST['username']); 

Any ideas on why I'm getting the errors and how to fix them?

Thanks.

Best guess is that it does not think it is being passed a string. Try echoing the $_POST... and/or assign this to a variable that is then used in the function call.

Short of creating a form to populate the post, I tried this on a php5 system with various values and got expected results for non-existent variables, nulls, strings, and numbers and could not duplicate your errors.

I searched for PHP and the error message and turned up some possibilities - a bug in an older version of PHP and the possibility that you are passing an array of values instead of just one value to the function (though when I tried this with a variable that was declared as an array, there was a specific error message that did not match your error.)

Thanks mab. I'll look at the post variables but I'm pretty sure they are all being passed. The same exact code works for me on my server and others, but when I put it on a certain server, I get those errors.

I'll check out the post variables when I get back to my computer.

Thank you for taking the time to look at this!

Try the function with static string and check the results.
b.t.w. what is the PHP version in your server?

Thanks for your replies.

I changed my function to this and now it works:

PHP Code:

function clean($v) { 

  $v = stripslashes(trim("$v")); 

  $v = nl2br("$v"); 

  $v = htmlentities("$v"); 

  return $v; 

} 

Why would my original function work on some servers but not others?

Thanks,

Tim
