Use templates created using ckeditor in codeigniter - php

Question

I am creating the templates using CKEditor. I need to replace the keys with its value, the keys are stored with its table name and columns to fetch in a table
e.g
tbl_template_bindings
id key table column
1 StudentFirstName tbl_User fname
2 StudentLastName tbl_User lname
3 TotalAmount tbl_payment due
and the user is bound to use those keys only, a kind of template. so consider we have created below template using CKEditor
Date: {{CurrentDate}}
Dear {{StudentFirstName}} {{StudentLastName}}, Your total amount is {{TotalAmount}}
please suggest any ideas will be helpful

Well, I just made this code for you, because I love CodeIgniter. Unfortunately I didn't test this code, but I am pretty sure #dEL, you will enjoy :)
CodeIgniter Helper File: Templatebuilder_helper.php
if ( ! function_exists('build_ck_template')) {
/**
* #param $template_txt
*/
function build_ck_template($template_txt)
{
// get all {{DATA}} as DATA in assoc array
preg_match_all('/{{(.*?)}}/', $template_txt, $matches);
// trim data & make array
$config = array_map('trim', $matches[1]);
// get CI instance
$CI = &get_instance();
// assuming you have user id in session - just for demo
$uid = $CI->session->userdata('uid');
// temp array var
$result = [];
// get data from table key, table & column
$query = $CI->db->query("SELECT * FROM tbl_template_bindings");
// collect all data
foreach ($query->result_array() as $row) {
array_push($result, $row);
}
// check one by one array key
foreach ($config as $key => $value) {
// skip date because its not in table
if ($value != 'CurrentDate') {
// first check if key exist in db data, get index
$found_at_index = array_search($value, array_column($result, 'key'));
// yes we got the key
if (false !== $found_at_index) {
// get data for requested key
$CI->db->select($result[$found_at_index]['column']);
// where clause
$CI->db->where('uid', $uid);
// query
$query = $CI->db->get($result[$found_at_index]['table']);
// if uid is unique, we want to return just one row
$query_result = array_shift($query->result_array());
// get key column data
$replace_value = $query_result[$result[$found_at_index]['column']];
// replace with original value
$template_txt = str_replace('{{'.$value.'}}', $replace_value, $template_txt);
}
}
}
// return Woah!!!
$template_txt = str_replace('{{CurrentDate}}', date('Y-m-d'), $template_txt);
return $template_txt;
}
}
/* End of file Templatebuild_helper.php */
/* Location: ./application/helpers/Templatebuilder_helper.php */
Example Uses:
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Class Controller
*/
class ControllerName extends CI_Controller {
public function __construct()
{
parent::__construct();
// load own template helper
$this->load->helper('Templatebuilder');
}
public function index()
{
// content template
$content = "Date: {{CurrentDate}}, Dear {{StudentFirstName}} {{StudentLastName}}, Your total amount is {{TotalAmount}}";
// build with real values
$this->load->view('template', array('temp_data' => build_ck_template($content)));
}
}
/* End of file data.php */
/* Location: ./application/controllers/ControllerName.php */

i'm not sure, but if i understand you correctly you simply need to parse some values and replace it with others
just create a model
class Template_Model extends CI_Model
{
public function build($strTemplate, $obj)
{
$arrData = (is_object($obj)) ? get_object_vars($obj) : $obj;
foreach($arrData AS $key => $val)
{
$strTemplate = str_replace("{{".$key."}}",$val,$strTemplate);
}
return $strTemplate;
}
}
and your controller
$this->load->model("template_model");
$str = "Date: {{CurrentDate}}, Dear {{StudentFirstName}} {{StudentLastName}}, Your total amount is {{TotalAmount}}";
echo $this->template_model->build($str, ["CurrentDate" => "2017-05-02", "StudentFirstName" => "Jon", "StudentLastName" => "Doe", "TotalAmount" => 100.22]);

You can use CI parsing library to parsing your DB to HTML page.
