Body
<p>I'm trying to load a library with the name Single_column. I create this library and I set it into the libraries folder. I have to mention at this point that I;m using the code Igniter framework. The Sinle_column class contain the following code:</p> <pre><code> <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Single_column { public function render( $id ) { $CI =& get_instance(); // DB calls // search for uri in db $CI->load->model('m_single_column'); $image = $CI->m_single_column->getImageURI( $id ); $text = $CI->m_single_column->getText( $id ); // ==== HEADER // eventually, this will be loaded from the db $header_data['title'] = "Single Column Demo"; $header_data['css'][] = "single_column"; $CI->load->view('v_header', $header_data); // ==== CONTENT $content_data['content'] = '<div class="content-block">'; $content_data['content'] .= '<div class="image">'; $content_data['content'] .= '<img src="' . base_url() . $image . '" width="200" height="133" alt="my tractor"/>'; $content_data['content'] .= '</div>'; $content_data['content'] .= $text; $content_data['content'] .= '</div>'; $CI->load->view('v_content', $content_data); // ==== FOOTER $CI->load->view('v_footer'); } } ?> </code></pre> <p>Now into the controller folder I have a class with the name: </p> <pre><code> <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class Master extends CI_Controller { function __construct() { parent::__construct(); } public function _remap($method) { // remap overrides function calls // search for uri in db $this->load->model('m_master'); $uri_id = $this->m_master->findURI(uri_string()); $page; if ($uri_id != false) { $this->{$page->controller}->render( $page->id ); } else { show_404(uri_string()); } } } ?> </code></pre> <p>The aforementioned code is from a tutorial and my problem is at the following line:</p> <pre><code> $this->{$page->controller}->render( $page->id ); </code></pre> <p>The displayed error is the following one:</p> <pre><code> Fatal error: Cannot access empty property in C:\xampp\htdocs\PhpProject1\application\controllers\master.php on line 24 </code></pre> <p>Actually I realized that it can't recognize the method 'render'. So, I tried the following lines of code into the if statement</p> <pre><code> $library= Single_column::$uri_id['id'];; $this->load->library($library); </code></pre> <p>But I received the following error: Fatal error: Class 'Single_column' not found in C:\xampp\htdocs\PhpProject1\application\controllers\master.php on line 22</p> <p>Moreover, the $uri_id returns an sql object. ButI want to pass only the id attribute of the object.</p> <p>Question: How Can I call a library? And how can I pass a value into a method of a class(render method)? Why the aforementioned lines that didn't work?</p>

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.
