Parser->Parser_String - El Forum - 11-30-2009
[eluser]tonydewan[/eluser]
This is a quicky. I'm sure someone has written this before, but I couldn't find anything in the forums after a few seconds of searching. Basically, I added a parse_string() method to the built in parser. This way, you can take a string of text(like say, from a DB) and parse out the same pseudo-variables. I went ahead and made it default to return a string (rather than appending to output, like the normal parse() method), because that made the most sense to me. This functionality would be welcome in the main library, I think.
Here is MY_Parser.php
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Parser extends CI_Parser {
/**
* Parse a string
*
* Parses pseudo-variables contained in the specified template,
* replacing them with the data in the second param
*
* @access public
* @param string
* @param array
* @param bool
* @return string
*/
function parse_string($string, $data, $return = TRUE)
{
$CI =& get_instance();
if ($string == '') return FALSE;
foreach ($data as $key => $val)
{
if (is_array($val))
{
$string = $this->_parse_pair($key, $val, $string);
}
else
{
$string = $this->_parse_single($key, (string)$val, $string);
}
}
if ($return == FALSE) $CI->output->append_output($string);
return $string;
}
}
