After digging into shorturls a bit I noticed that they don't work when the client's request is redirected (after submitting a form without any valid data for instance)
To resolve this I wrote a hack for pnRedirect and I'm posting it here for feedback and sharing.
Open /includes/pnAPI.php and paste part 1 around line 1005 between the part where it says:and the part where it saysCode
return "$proto$server$path/";
}Code
/**
* Carry out a redirect
Part 1:Code
//------------------- ShortURLS redirect hack Start part 1 ----------------------------------------------->
function redirect_get_template ($tpl_name, &$tpl_source, &$smarty_obj)
{
$tpl_source = '{$url}';
return true;
}
function redirect_get_timestamp($tpl_name, &$tpl_timestamp, &$smarty_obj)
{
$tpl_timestamp = time();
return true;
}
function redirect_get_secure($tpl_name, &$smarty_obj)
{
// assume all templates are secure
return true;
}
function redirect_get_trusted($tpl_name, &$smarty_obj)
{
// not used for templates
}
//<------------------ ShortURLS redirect hack End part 1 ------------------------------------------------
Now paste part 2 a little lower (around line 1055 if you already pasted the first code snippet) between where it says:Code
// Always close session before redirect
if (function_exists('session_write_close')) {
session_write_close();
}
and the part where it says:Code
if (preg_match('!^http!', $redirecturl)) {
// Absolute URL - simple redirect
header("Location: $redirecturl");
Part2:Code
//------------------- ShortURLS redirect hack Start part 2 ----------------------------------------------->
if(pnModGetVar('Xanthia', 'shorturls') == 1) {
//we need quotes or the outputfilter won't recognize the url
$redirecturl = '"'.$redirecturl.'"';
//Get a reference to Smarty (pnRender doesn't seem to work)
$pnSmarty =& new Smarty('Xanthia');
//Configure the Smarty instance
$pnSmarty->caching=false;
$pnSmarty->use_sub_dirs=false;
$pnSmarty->compile_dir=pnConfigGetVar('temp') . '/Xanthia_compiled';
$pnSmarty->plugins_dir='../../../modules/Xanthia/plugins';
// create a custom resource using the functions pasted in earlier
$pnSmarty->register_resource("redirect", array("redirect_get_template",
"redirect_get_timestamp",
"redirect_get_secure",
"redirect_get_trusted"));
$pnSmarty->assign('url', $redirecturl);
$pnSmarty->load_filter('output', 'shorturls');
//use the custom resource
$redirecturl = $pnSmarty->fetch("redirect:url.tpl");
//remove the quotes added earlier
$redirecturl = str_replace('"', '', $redirecturl);
}
//<------------------ ShortURLS redirect hack End part 2 ------------------------------------------------
Now save and close the file and your shorturl-redirect should work.
Any feedback will be greatly appreciated.
Happy coding!
