jquery - Undefined index: posts_start on one localhost machine, but not on another? with Laravel 4 -

-

i have been trying set "load-more" functional widget, , successful earlier today on localhost. however, on computer (same mac os, mamp, etc...), getting error session variable: undefined index: posts_start.

in javascript, these relevant lines:

<?php $number_of_posts = 2; ?>; //<?php $_session['posts_start'] = $_session['posts_start'] ? $_session['posts_start'] : $number_of_posts; ?>; <?php $_session['posts_start'] = 2 ?>;  var start = <?php echo $_session['posts_start']; ?>;

this using laravel 4, have session running current user (no need use session_start()). not sure why isn't working on machine, working on another. thoughts? thank you.

i use laravel's session library. lib can handle situations beautifly...

var start = <?=session::get('posts_start', 2) ?>;  // or this, if use blade syntax var start = {{ session::get('posts_start', 2) }};

what call do? tries posts_start session, , fallbacks number 2, if number not set in session.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
