quote-delineated tag sets

snippet to surround a tag with “smart quotes” if it contains any odd characters. i.e. to display tags entered in a flickr-like style (space separated except inside quotes)



tag.gsub(/^/,'“').gsub(/$/,'”') if tag[0].match(/[^A-Za-z0-9\-_.]/)

Toggle an element's display

Sometimes you have a content that shouldn't display
by default. You can provide a link to display/hide
that content

Don't display me

Let php show all errors

korakot (Korakot Chaovavanich) — Mon, 20 Mar 2006 08:35:58 GMT

I have wondered why my php script doesn't show
errors like it did before. It seems my server admin
has default config set not to show the errors.

Here's how to override it.



error_reporting(E_ALL);

ini_set('display_errors', '1');

BTW, it's really a pain to code in a language that
demand a ';' after every line.
