How to return an empty string instead of null for $this->input->post() - eldan88 - 03-18-2015
Hey Guys,
As mentioned in the title, I want to return an empty string because mysql won't let me insert value as NULL. I tried making the following changes from this
PHP Code:
public function post($index = NULL, $xss_clean = NULL)
{
return $this->_fetch_from_array($_POST, $index, $xss_clean);
}
to this
PHP Code:
public function post($index = "", $xss_clean = NULL)
{
return $this->_fetch_from_array($_POST, $index, $xss_clean);
}
But it still returns NULL. Any suggestions on how i can do that?

Nevermind guys! I just figured to set the mysql column to NULL

$the_string = (string) $this->input->post('the_string');
