You do not have a function called 'write_log' within the class in the above script.

If the function 'write_log' is defined outside the class, you cannot reference it as you are trying as it is not registered in the class.

Take a look at this

Also, use code tags.

im not sure how to fix this error i kinda understand what your saying. but I have no idea how to fix it.

this is the line of code in question
write_log($query, $this->debug_filename, 0, 'txt');

i thought this was my function

[Will Gresham]

That line would look for a function called write_log, and send it the values
$query
$this->debug_filename
0
and 'txt'

write_log is not a PHP function, so you will need to have a custom one defined somewhere with this name.

So, somewhere in your script you will need to have the function telling it what to do, e.g.:

function write_log($used_query, $filename, $status, $type) {
  // Do something with the values here
}

That is just an example, I don't know what the values you are sending are for so the vars I used may not be appropriate.
