• FireFox has problems telling the time

  Friday, January 20th, 2012

  Who’d have thought that FireFox has a problem telling the time? If you try and create a new ‘Date()’ object and set the time to zero, most browsers return 1st Jan 1970 at 00:00, however FireFox seems to think that I’m currently in BST and return 1:00am. Magic:

  Here’s what Chrome says:
  

  And here’s what FireFox says:
  

  So, how does one get around this? Well with a bit of cunning it seems. FireFox returns ‘Date.getTimezoneOffset()’ as -60 and this is what we need to put the clocks back:

  function formatTime(t)
  {
      // a fix for FireFox's time issue
      var o   = t.getTimezoneOffset();
      var n   = o ? o / -60 : 0;
     
      return appendZero( t.getHours() - n ) + ':' + appendZero( t.getMinutes() ) + ':' + appendZero( t.getSeconds() )
  }
  
  var d = new Date();
  
  d.setTime( 0 );
  
  console.log( formateTime( d ) );

• Auto-disabling WordPress’s ‘wpautop’ function

  Friday, January 6th, 2012

  WordPress has a lovely little function called ‘wpautop‘. It simply converts line spaces in the posts we write to nice paragraphs. That’s cool and all, but what if you’re writing your own paragraphs in the HTML tab when writing a post? Well there are a number of plugins out there that allow you to disable this function on a post-by-post basis, but I’m lazy, I want WordPress to disable it when there’s HTML in a post, so I wrote a little filter to handle it for me:

  function handle_content($c)
  {
      global $post;
     
      if ( strpos( $c, '<' ) === 0 )
      {
          remove_filter( 'the_content', 'wpautop' );
      }
     
      return $c;
  }
  
  add_filter( 'the_content', 'handle_content', 9 );

  Call me silly or stupid, but this works perfectly for me. Simply it checks the very first character of a post, if it’s ‘<’ then it assumes the post is HTML based and disables the ‘wpautop’ filter.

• Accessing WordPress’s ‘bloginfo’ from a post

  Friday, January 6th, 2012

  If you’re like me then you like full control over your posts. In a recent post I wanted to include a picture that was within the theme directory rather than having uploaded it. Now I can’t be bothered to write out the full URL to the theme so instead I created a quick shortcode that allows you to access WordPress’s ‘bloginfo‘ from within your posts:

  function handle_shortcode_bloginfo($a)
  {
      return get_bloginfo( $a[ 'get' ] );
  }
  
  add_shortcode( 'bloginfo', 'handle_shortcode_bloginfo' );

  To use it you simply add [bloginfo get=”bloginfo_to_get”] and that’s it.
