This below code is part of View from CodeIgniter Docuemnt
https://www.codeigniter.com/userguide3/libraries/parser.html
and Controller like this
When run on web browser all array data will display at braces same key name.
and associative array will display in {blog_entries} .......... {/blog_entries}
But, site_url cannot display in {blog_entries} .......... {/blog_entries}
Create test page controllers/Welcome.php
<?phpdefined('BASEPATH') OR exit('No direct script access allowed');class Welcome extends CI_Controller { public function index() { $this->load->helper('url'); $this->load->library('parser'); $data = array( 'site_url' => site_url(), 'blog_title' => 'My Blog Title', 'blog_heading' => 'My Blog Heading', 'blog_entries' => array( array('title' => 'Title 1', 'body' => 'Body 1'), array('title' => 'Title 2', 'body' => 'Body 2'), array('title' => 'Title 3', 'body' => 'Body 3'), array('title' => 'Title 4', 'body' => 'Body 4'), array('title' => 'Title 5', 'body' => 'Body 5') ) ); $this->parser->parse('welcome_message', $data); }}?>
Create view file views/welcome_message.php
<!DOCTYPE html><html lang="en"><head> <meta charset="utf-8"> <title>{blog_title}</title> <style type="text/css"> body { background-color: #fff; margin: 40px; font: 13px/20px normal Helvetica, Arial, sans-serif; color: #4F5155; } </style></head><body> <h3>H3 : {blog_heading}</h3> <p>ลิงค์ : {site_url}</p> {blog_entries} <h5>H5 : {title}</h5> <p>P : {body}</p> <p>Link : {site_url}</p> {/blog_entries}</body></html>
When reload page again {site_url} is a normal text not display link url
For solve this problems
Override parser class with below codeCreate file MY_Parser.php at this path application/libraries/MY_Parser.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');/** * Overrides the CI Template Parser to allow for multiple occurrences of the * same variable pair * */class MY_Parser extends CI_Parser { // -------------------------------------------------------------------- /** * Parse a template * * Parses pseudo-variables contained in the specified template view, * replacing them with the data in the second param * * @param string * @param array * @param bool * @return string */ public function parse($template, $data, $return = FALSE) { $template = $this->CI->load->view($template, $data, TRUE); $results = $this->_parse_double($template, $data); $results = $this->_parse($results, $data, TRUE); if ($return === FALSE) { $this->CI->output->append_output($results); } return $results; } // -------------------------------------------------------------------- /** * Parse a single key/value * * @param string * @param string * @param string * @return string */ protected function _parse_double($results, $data) { $replace = array(); preg_match_all("/\{\{(.*?)\}\}/si", $results, $matches); foreach ($matches[1] as $match) { $key = '{{'.$match.'}}'; $replace[$key] = isset($data[$match]) ? $data[$match] : $key; } $results = strtr($results, $replace); return $results; }}// END Parser Class/* End of file MY_Parser.php *//* Location: ./application/libraries/MY_Parser.php */
Then edit your view file views/welcome_message.php
in Variable Pairs if call out of pairs variable used double braces
{{site_url}}
<!DOCTYPE html><html lang="en"><head> <meta charset="utf-8"> <title>{blog_title}</title> <style type="text/css"> body { background-color: #fff; margin: 40px; font: 13px/20px normal Helvetica, Arial, sans-serif; color: #4F5155; } </style></head><body> <h3>H3 : {blog_heading}</h3> <p>ลิงค์ : {site_url}</p> {blog_entries} <h5>H5 : {title}</h5> <p>P : {body}</p> <p>Link : {{site_url}}</p> {/blog_entries}</body></html>
Now go to reload page you can see link URL at {{site_url}}
