Template Parser Class Improvement

[eluser]adamp1[/eluser]
Right well after some work I think I have a solution which works. It replaces all none assigned {variable} tags and {variable}{/variable} pairs.

To get it to work you need to add several lines to the Parser.php library

In the parse method find the lines:

Code:

if ($return == FALSE)
{
    $CI->output->final_output = $template;
}

Now add just before that block this

Code:

if (preg_match_all("(".$this->l_delim."([^".$this->r_delim."/]*)".$this->r_delim.")", $template, $m)){

    foreach($m[1] as $value)
    {
        $template = preg_replace ("(".$this->l_delim.$value.$this->r_delim."((?!".$this->l_delim.$value.$this->r_delim.")|.|[\r\n])*".$this->l_delim."/".$value.$this->r_delim.")", "", $template);
        $template = str_replace ("{".$value."}", "", $template);
    }
}

What it does is it replaces all variable pair combinations top down. This includes all nested pairs inside the parent. It also replaces any single {variable} replacement strings.

It does not replace the ##THIS TEXT## in the following example:

Code:

{test}
Test
{/test}
##THIS TEXT##
{test}
Test
{/test}

Maybe they can check over the code addition and implement it into the next release, don't know about others but it seems a rather usefull addition.
