I'm really confused as to why this is happening.

I have a controller named main.php and a view main_template.php

I created a custom function in main.php that returns the number of rows in a table. But when I goto main_template.php and insert

echo functionName();

I get the following error.

[quote][b]Fatal error[/b]: Call to undefined function functionName()[/quote]

What am I doing wrong?

hi! Echo this->functionName()

That didn't work.

I'm now getting the following error

[b] [b]Fatal error[/b]: Call to undefined method CI_Loader::getPropNum() in [b]C:\wamp\www\codeign\application\views\main_template.php[/b][/quote][/b]

Let me see your controller code.

[ufodisko]

I created a new_helper.php and placed my custom functions in it, the file is in 'libraries'

This is the code of the new helper

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');



if ( ! function_exists('test_method'))

{

function test_method($var = '')

{

return $var;

}



function getPropNum() {

$query = $this->db->query('SELECT * FROM properties');

return $query->num_rows();

}

}

The first function is a test function and it works perfectly when called from the view.

echo test_method('Hello World');

However, the second function is the one that's making errors. It's a simple function to get the number of rows in a table.

Then I loaded the helper inside my controller main.php

$this->load->helper('new_helper');

Then inside my view main_template.php, I called my function

echo getPropNum();

PS: when I call

Hello [member='ufodisko']

Just to make sure that it will work for you try to add this lines at the beginning of your template (main_template.php) .

<?php

$ci =  &get_instance();

$ci->load->helper('new_helper'); ?>

Don't worry to have as many times as you like the $this->load->helper(), library(), model(), ...e.t.c. as it will only load once. For example if you have already called the same $this->load->helper at your controller it is ok to call it to your template too, as it will not affect anything.

P.S. I moved the topic to the General topic as it is not related with grocery CRUD

I'm still getting the same error

[b]Why would the test_method() function load but not the getPropNum() ?[/b]

[victor]

why your helper is in "libraries"? remove your file to "helpers".

[ufodisko]

My helper is in /application/helpers/new_helper.php

[victor]

if you call this function in controller is it work?
