Hi,
i made an extension to the template class of phplib to support frames..
I have two concerns,
1). I am making temporary files using fopen($filename,'w'); to create a dynamic frame set. Interms of traffic on the site and performance... could this really slow things down.. ?
2). i made a method 'parse_frame($target,$varname)' i tried to copy the existing parse method so as to set up the $target as a VARKEY and the parsed template frame file becomes the VARVALUE.. in order to print the frame string i have i have to do
print $template->parse_frame ("frame",array("element","element2","etc")); instead of using $template->p("frame");
I have included the code.. please i would love feed back on the best way to keep navigational elements dynamic as well as content elements, and keeping duplicate code to a minimum..
$t = new templateX("C:/apache group/apache/phplib-7.4-pre1", "keep");
define variables named page and box, referencing files
define variables named page and box, referencing files
$t->set_file(array(
"frame" => "aboutusindexframe.tpl",
"history" => "history.tpl",
"nav" => "nav.tpl",
"side" => "side.tpl"));
define the variables TITLE and PAGETITLE
$t->set_var("IMGDIR","/images");
$t->set_web_path("/tempframes/");
$t->set_temp_dir($t->root . "/tempframes");
print $t->parse_frame("frame", array("history","nav","leftbottom","side"));
