parse_template question

[Firas Darwish]

Hi,,

how can i use the parse_template hook to parse ALL the templates at once ?

[Simon Lloyd]

What do you mean parse all templates at once? what is it you want to do?

[Firas Darwish]

i want to use str_replace in all the templates

[Simon Lloyd]

Then just use your code in a plugin using the parse templates hook, it should work as you want.

[Firas Darwish]

to parse a SINGLE template i would use

PHP Code:

$vbulletin->templatecache['TEMPLATE_NAME'] = str_replace('Yahoo','Google',$vbulletin->templatecache['TEMPLATE_NAME']); 


can you give me an example of how to parse ALL the templates using parse_templates hook ?

[Simon Lloyd]

I suppose you could try $globaltemplates, but ideally for an str replace you'd build an array of template names.

This might help you write the function, this is directly out of /includes/functions_misc and its the section where they do an str replace on templates

PHP Code:

function replace_template_variables($template, $do_outside_regex = false)
{
    // matches references to specifc arrays in templates and maps them to a better internal format
    // this function name is a slight misnomer; it can be run on phrases with variables in them too!

    // include the $, but escape it in the key
    static $variables = array(
        '\$vboptions' => '$GLOBALS[\'vbulletin\']->options',
        '\$bbuserinfo' => '$GLOBALS[\'vbulletin\']->userinfo',
        '\$session' => '$GLOBALS[\'vbulletin\']->session->vars',
    );

    // regexes to do the replacements; __FINDVAR__ and __REPLACEVAR__ are replaced before execution
    static $basic_find = array(
        '#\{__FINDVAR__\[(\\\\?\'|"|)([\w$[\]]+)\\1\]\}#',
        '#__FINDVAR__\[\$(\w+)\]#',
        '#__FINDVAR__\[(\w+)\]#',
    );
    static $basic_replace = array(
        '" . __REPLACEVAR__[$1$2$1] . "',
        '" . __REPLACEVAR__[$$1] . "',
        '" . __REPLACEVAR__[\'$1\'] . "',
    );

    foreach ($variables AS $findvar => $replacevar)
    {
        if ($do_outside_regex)
        {
            // this is handles replacing of vars outside of quotes
            do
            {
                // not in quotes = variable preceeded by an even number of ", does not count " escaped with an odd amount of \
                // ... this was a toughie!
                $new_template = preg_replace(
                    array(
                        '#^([^"]*?("(?>(?>(\\\\{2})+?)|\\\\"|[^"])*"([^"]*?))*)' . $findvar . '\[(\\\\?\'|"|)([\w$[\]]+)\\5\]#sU',
                        '#^([^"]*?("(?>(?>(\\\\{2})+?)|\\\\"|[^"])*"([^"]*?))*)' . $findvar . '([^[]|$)#sU',
                    ),
                    array(
                        '$1' . $replacevar . '[$5$6$5]',
                        '$1' . $replacevar . '$5',
                    ),
                    $template
                );
                if ($new_template == $template)
                {
                    break;
                }
                $template = $new_template;
            }
            while (true);
        }

        // these regular expressions handle replacement of vars inside quotes
        $this_find = str_replace('__FINDVAR__', $findvar, $basic_find);
        $this_replace = str_replace('__REPLACEVAR__', $replacevar, $basic_replace);

        $template = preg_replace($this_find, $this_replace, $template);
    }

    // straight replacements - for example $scriptpath becomes $GLOBALS['vbulletin']->scriptpath
    static $str_replace = array(
        '$scriptpath' => '" . $GLOBALS[\'vbulletin\']->scriptpath . "',
        '$navbar_reloadurl' => '" . $GLOBALS[\'vbulletin\']->reloadurl . "',
    );
    $template = str_replace(array_keys($str_replace), $str_replace, $template);

    return $template;
}
