How to use the variable passed from form_open?

[eluser]Katsune[/eluser]
Hey guys,

View named printdog.php

Code:

<?php
   $idFromPrintDog = $records['id'];

   echo form_open('mainController/deleteRecord',$idFromPrintDog);
   echo form_submit('','Submit');
   echo form_close();
?>

Controller named mainController

Code:

public function deleteRecord($idFromPrintDog){
echo $idFromPrintDog;
}

Can you guys tell me why I'm getting "missing argument and undefind variable"? Am I calling the value from the view correctly?
I've been checking the documentation but there's no controller example on in the topic for form helper.

Second argument in form_open() function should be an associative array (if needed).
Check one more time form helper in user guide.
You should be able to solve this concatenating, so instead comma use dot:

Code:

<?php
   $idFromPrintDog = $records['id'];

   echo form_open('mainController/deleteRecord/' . $idFromPrintDog); //check this line
   echo form_submit('','Submit');
   echo form_close();
?>
