How to handle controller for every reload ? - El Forum - 09-30-2008

How can I handle outer controller ? e.g. in every site, $this->load->view('header'); and $this->load->view('footer'); get included.
I post already another thread, nearly with the same thematic ... how can I load EVERYTIME the script runs through, definied functions like a language include for the menu inside the "header" ? Or if the menu must get dynamically out of a database ? What is the best way to include some functions/controller/models at every page load ?

That's a good question. You'll perhaps find utilities that do this for you (advanced templates classes, etc) in the wiki. My personnal trick is to create an helper function that I call at the end of any controller function, and that adds all the stuff. Something like :
Code:
// inside controller function
... processing ...
$main_html = $this->parser->parse('whatever',$tplarray,true);
return render_output($main_html);
}and an helper like :
Code:
function render_output($main_html) {
$ci=&get;_instance();
$tpl = array ('main'=>$main_html);
$tpl['left_menu'] = $ci->menu->get_html();
$tpl['other_part'] = other_thing();
$ci->parser->parse('body',$tpl);
}That's enough, and you have the choice not to call your helper function, for example in case of a controller method returning an AJAX response in json, or whatever.

Here's the bit you are missing - your view can call other views. I usually pass the content bits within each page as an array from the controller, sort of like this:
My Controller (snippet):
Code:
<?php
// I'm skipping the other controller code
$data['contents'] = array(
'section_a',
'section_b',
'etc'
);
// load your main view from the controller and pass over your array
$this->load->view('my_view', $data);My view:
Code:
<html>
<body>
<?php $this->load->view('header'); ?>
// loop through your array and add your views
<?php
foreach($contents as $section)
{
$this->load->view($section);
}
?>
<?php $this->load->view('footer'); ?>
</body>
</html>This is a very simple example at least to get the idea across. I recall having trouble absorbing this when I first started with CI.

Here's a quick example using a simple app that I'm currently building.
I've got two global views header.php and main.php.
Each file has <?php echo $content; ?>.
header.php is the html for the <head> and main.php has everything else.
I then have more views, with 2 or 4 columns, which I can use as I want.
In the controller I have
Code:
// load some JS first...
$head['content'] = $this->load->view('jquery', '', TRUE);
// then get the html...
$html = $this->yourmodel->get();
$data['content'] = $this->load->view('two-col', $html, TRUE);
$this->load->view('_global/header', $head);
$this->load->view('_global/main', $data);
