Hello, i want to know if there is any possibility to disable the
output of the rendering template when an exception occurs, right now
processing stop if there is any exception but the page is shown
until the error was made, i use the execute method, not the
echoExecute, which is supposed not to output the document.
I need to create a webpage that is going to be send by email, not to
display on the web browser, if the templates throws an exception i
can catch it, but i don't want it to be displayed truncated on the
web browser, is there any way to disable this behavior ?
Hm, execute() uses buffering already, so it shouldn't output
anything... unless you get a fatal error during execution of the
template. In that case PHP takes over and outputs PHPTAL's buffer
anyway. Only fatal errors (mostly invalid syntax in php: or your
custom modifiers if you have any) could be problematic, regular errors
(unclosed tags, missing variable) should always end cleanly.
Does catching of exceptions help?
try {
$phptal->execute()
}
catch(PHPTAL_Exception $e) {
// do whatever you'd do when template fails, $e->getMessage() will
give you the error.
}
If not, then try:
function on_die_handler($output)
{
global $can_output;
if ($can_output) return $output; else return '';
}
ob_start('on_die_handler');
$can_output=false;
$phptal->execute();
$can_output=true;
ob_end();
