Custom Helper Problem ? - jocm.aguiar - 07-11-2016
Hi guys.
Who can help me solve a problem?
I made a helper in the CI3 standard but I displays the following error message:
An uncaught Exception was encountered
Type: Error

}
}

you can't use $this in function. Is base in PHP.
RE: Custom Helper Problem ? - InsiteFX - 07-12-2016
$ci->session->set_userdata($ws_session_data);

I managed to fix the code, thanks. But introduces a new error:

Which leads to the question, what is on line 36 of /application/controllers/apps/Runcode.php? (preferably any other code required to understand that line, as well) PHP's error messages are a mixed bag, but they usually point you in the right direction.

Ok.
Controller File: Runcode.php
Method:
31 // Paramente variable receive method:
32 public function accesscheck($ws_safe_email) {
33 // load helper:
34 $this->load->helper('sessdata');
35 $feedbk = check($ws_safe_email);
36 echo $feedbk;
37 }

It looks like it may be in your check() method, maybe its trying to use a string and it's looking for an array?

I rectified the code and can get the result of the function by the 'echo'. But I can not see the result in view, when step by parameter ?
Code Funcional :
public function accesscheck($ws_safe_email)
{
$output = check($ws_safe_email);
echo $output;
}
Nonfunctional code : Shows the view but do not see the function output ?
public function accesscheck($ws_safe_email)
{
$output['see'] = check($ws_safe_email);
$this->load->view('apps/runcode', $output);
}
View:
<?php $see; ?>
RE: Custom Helper Problem ? - InsiteFX - 07-14-2016
You are returning this check($ws_safe_email); as an array $data
Another thing I just noticed is that your assigning the result obj from the query to the session user_data,
the user_data is expecting an associate array not an object.
you need to return a result_array() not just a result()

I noticed the code assigning only a variable as the previous post. Now the output of the problem function result? I forgot to declare the (echo) of the array () in view.php. This running perfect.
Grateful.
