This would be useful to: 1. remove comments which are present only to make the template easier to maintain. These are for the use of the site builders and should never be sent to the user. 2. remove untouched BEGIN/END block comments. I often have either/or blocks, one of which gets deleted and the other one stays there, comments and all. The user has no need to see those comments. Default behaviour could be for finish to strip comments from the template, just as it currently processes remaining {} tags. Original post from Sven: Hello Give it an easy way to delete comments in a template file so that the output not have the comments? I will not use the HTML-method (<!-- ... -->) for commenting my template files. My idea is a comment beginn with '{*' and end with '*}' or so. The first idea was to make an owe function in template.inc to filter that comments. But i hope it give an easy way as an own function. PS: I working with a cvs version of phplib. ---------------------------------------------------------------------- Comment By: Sven Eichler (koala_s) Date: 2004-05-02 20:47 Message: Logged In: YES user_id=253680 --- /CVS/php-lib-stable/php/template.inc 2004-04-22 23:17:01.000000000 +0200 +++ /CVS/mylib/template.inc.php 2004-05-02 19:31:16.000000000 +0200 @@ -52,6 +52,13 @@ * */ +/* + * Change log by Koala 02.05.2004 + * + * new function delete_comment($str) + * + */ + /** * The template class allows you to keep your HTML code in some external files * which are completely free of PHP code, but contain replacement fields. @@ -170,6 +177,24 @@ */ var $last_error = ""; + /** + * Comments in templates can begin with this. + * + * @var string + * @access public + */ + var $left_delimiter = '{*'; + + /** + * Comments in templates can end with this. + * + * @var string + * @access public + */ + var $right_delimiter = '*}'; + + + / ****************************************************************************** * Class constructor.
