[Solved] isset not working correct. - wolfgang1983 - 04-22-2015
Hello all, I am trying to make a <body class="<?php echo $class;?>"> to help with my specialized css
For example if isset uri->segment(1) and (2) then would show something like this <body class="page-category-121"> which is correct
But if the uri segments not set I need it to be <body class="common-home"> that would mean it on base url page the home page for some reason when on home page it shows just <body class="-">
When on main url / base url how can I make it show <body class="common-home">
PHP Code:
$page_id = $this->input->get('page_id');
$path = $this->input->get('path');
$route = $this->uri->segment(1).'/'.$this->uri->segment(2);
if (isset($route)) {
if (isset($page_id)) {
$class = '-' . $page_id;
} elseif (isset($path)) {
$class = '-' . $path;
} else {
$class = '';
}
$data['class'] = str_replace('/', '-', $route).$class;
} else {
$data['class'] = 'common-home';
}

The problem is that the variables $page_id and $path are set so will always evaluate to TRUE. Use empty() instead
Code:
$page_id = $this->input->get('page_id');
$path = $this->input->get('path');
$route = $this->uri->segment(1).'/'.$this->uri->segment(2);
if ($route != '/')
{
if (! empty($page_id))
{
$class = '-' . $page_id;
} elseif (! empty($path))
{
$class = '-' . $path;
} else
{
$class = '';
}

$this->uri->segment(x) always returns a value, and so will $this->input->get(x), so they will always pass "isset". If you are using CI2.x, they return FALSE if the segment or get parameter didn't exist. So that's probably what you want to check for (!==FALSE) instead of isset().

Thanks every one works great now.
