Body
I moved my scraping/parsing PHP code to Codeigniter recently. It uses cURL and SimpleHtmlDom class to retrieve data from the target URL which is later processed by the model functions several other libraries. There are several requests to external Webs and APIs so the original PHP script took up to 20 seconds to load the complete page, but it was OK because the PHP was split into several blocks and while the processes lower down were running the page was already rendering HTML, which could be read by the user while the rest of the data was being processed and displayed. The problem with switching to Codeigniter is that no HTML is rendered until the Controller script has been executed completely, even if the data processes are split into blocks and loaded by separate Views. <pre><code><?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class HomePage extends CI_Controller { public function index() { $this->load->library('simple_html_dom'); $this->load->library('library1'); $this->load->library('library2'); $this->load->library('library3'); $this->load->model('HomePage_model'); $this->load->view('templates/header'); $targeturl = 'http://www.example.com'; $variable1 = library1::method1($targeturl); $variable2 = $this->HomePage_model->method2($targeturl); $data1 = array('variable1' => $variable1, 'variable2' => $variable2); $this->load->view('first_set_of_data', $data1); $variable3 = library2::method2($targeturl); $variable4 = $this->HomePage_model->method3($targeturl); $data2 = array('variable3' => $variable3, 'variable4' => $variable4); $this->load->view('second_set_of_data', $data2); $curlinfo = $this->HomePage_model->cURLmethod($targeturl); $data3 = array('curlinfo' => $curlinfo); $this->load->view('third_set_of_data', $data3); $this->load->view('sidebar'); $this->load->view('templates/footer'); } } /* End of file homepage.php */ /* Location: ./application/controllers/homepage.php */ </code></pre> I'm not trying to optimize my code so it runs faster, it's already been revised several times... what I'm trying to do is to load Views progressively as the data corresponding to each View is ready, while the data for the other Views is being processed.

1. COthe best way to do it, in codeigniter or in any framework is to use the **ajax** methodology to load the extra data after page loading.

2. COThanks @Ahmad for your help. I'm new to Ajax, could you develop on how it could be implemented or link to an article where I could start learning?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
