_output called, but $output is empty - El Forum - 03-07-2011
[eluser]Unknown[/eluser]
I have a method in my controller
Code:
function test() {
print "test";
}
function _output($output) {
var_dump($output);
}_output() is being called, but $output is blank, and the output is sent, so that I see "test" first, then the var dump of an empty string.
I don't have caching on, no compression, no hooks, nothing I can see that would cause this. Any suggestions?
Thx,
Tac

I don't see in your question where you have defined
Code:
$outputI think I am missing something.

Did you look at CodeIgniters Output Library?

CodeIgniters Output library calls _output() in your controller if it exists, passing all buffered output to it:
Code:
if (method_exists($CI, '_output'))
{
$CI->_output($output);
}
else
{
echo $output; // Send it to the browser!
}The problem here is that direct output generated in the controller by things like echo, print, or var_dump are not buffered by the Output library, which is probably why $output is empty.
