Unable to load page with codeigniter - php

Question

On my codeigniter HMVC project. When I try to run my first isset statement in modules foreach section. If I uncomment the code below then, fire fox loads page error The connection was reset.
But if I comment out the code like below the page loads fine very strange.
//if (isset($part[0]) && $this->setting->get($part[0] . '_status')) {
// $data['modules'][] = Modules::run('catalog/module/'.$part[0].'/index');
//}
For some reason does not like using isset($part[0])
How code works
$part[0] it returns the module name example category
$part[1] it returns the module number example 66 category.66
$this->setting->get($part[0] . '_status') returns either 1 if
enabled or 0 if disabled.
What could be the cause of page not loading when I uncomment the code above. Any suggestions
Controller
<?php
class Column_left extends MX_Controller {
public function index() {
$this->load->model('catalog/extension/model_extension_extension');
$this->load->model('catalog/design/model_design_layout');
$route = $this->uri->segment(1).'/'.$this->uri->segment(2);
// $route outputs like pages/category
$layout_id = 0;
if (!$layout_id) {
$layout_id = $this->model_design_layout->get_layout($route);
}
if (!$layout_id) {
// Setting library autoloaded
$layout_id = $this->setting->get('config_layout_id');
}
$data['modules'] = array();
$modules = $this->model_design_layout->get_layout_modules($layout_id, 'column_left');
foreach ($modules as $module) {
$part = explode('.', $module['code']);
echo $part[0];
// Setting library autoloaded
if (isset($part[0]) && $this->setting->get($part[0] . '_status')) {
$data['modules'][] = Modules::run('catalog/module/'.$part[0].'/index');
}
if (isset($part[1])) {
$setting_info = $this->model_extension_module->get_module($part[1]);
if ($setting_info && $setting_info['status']) {
$data['modules'][] = Modules::run('catalog/module/'.$part[0].'/index', $setting_info);
}
}
}
// Setting library autoloaded
if (file_exists(DIR_TEMPLATE .$this->setting->get('config_template'). '/template/common/column_left_view.php')) {
$this->load->view('theme/'.$this->setting->get('config_template').'/template/common/column_left_view', $data);
} else {
$this->load->view('theme/default/template/common/column_left_view', $data);
}
}
}
View
<?php if ($modules) { ?>
<column id="column-left" class="col-sm-3 hidden-xs">
<?php foreach ($modules as $module) { ?>
<?php echo $module; ?>
<?php } ?>
</column>
<?php } ?>

After working on it all after noon, was able to find the cause of the issue.
In my catalog modules folder I had 2 controllers named the same in different folders, catalog/category & module/category. Even though they were in different folders one was over riding other and causing page load error on fire fox.
How I solved problem. By renaming the controller in subfolder catalog to categories I refreshed page and then works.
I also cleaned up code here.
<?php
class Column_left extends MX_Controller {
public function index() {
$this->load->model('catalog/design/model_design_layout');
$route = $this->uri->segment(1).'/'.$this->uri->segment(2);
$layout_id = 0;
if (!$layout_id) {
$layout_id = $this->model_design_layout->get_layout($route);
}
if (!$layout_id) {
$layout_id = $this->setting->get('config_layout_id');
}
$data['modules'] = array();
$results = $this->model_design_layout->get_layout_modules($layout_id);
foreach ($results as $result) {
$part = explode('.', $result['code']);
if (isset($part[0]) && $this->setting->get($part[0] . '_status')) {
$data['modules'][] = Modules::run('catalog/module/'.$part[0].'/index');
}
if (isset($part[1])) {
$this->load->model('catalog/extension/model_extension_module');
$setting_info = $this->model_extension_module->get_module($part[1]);
if ($setting_info && $setting_info['status']) {
$data['modules'][] = Modules::run('catalog/module/'.$part[0].'/index', $setting_info);
}
}
}
$this->load->view('theme/default/template/common/column_left_view', $data);
}
}
