将codeigniter数据传递给简单的html dom url变量

Question

I have a problem. I would like to pass my Codeigniter Mysql variables (which I can use at the template as {{ category:country }} using this library http://simplehtmldom.sourceforge.net/ ) at a simple HTML-DOM URL variable. I tried lot of variation without result.

Here is the beginning of my code:

<?php

include_once('simple_html_dom.php');

ini_set('display_errors', true);
error_reporting(E_ALL);


$url = 'http://address.com/".{{ category:country }}."/'; 

?>

I would like to open the address, like if I got the germany variable, then parse this: http://address.com/germany .

Many thanks!

If I understand the issue correctly then what you want might be tricky or impossible.

Basically, Simply HTML DOM is working with code in memory so when you feed it $url then it is trying to visit a URL named http://address.com/".{{ category:country }}."/

The template parser acts upon PHP's output buffer so it's not invoked until it is ready to call all the ob_* functions

If your templating engine supports it then you will need to do something like this:

<?php

include_once('simple_html_dom.php');

ini_set('display_errors', true);
error_reporting(E_ALL);

$url = 'http://address.com/".{{ category:country }}."/'; 

// Find a function which will parse the string you have passed into it
$url = FAKE_FUNCTION_templating_engine_PARSE_NOW($url);

// At this point, Simple HTML DOM will be able to properly use the $url
