Ordinal Suffixes in PHP

will — Mon, 02 Mar 2009 21:23:55 +0000

function ordinalize($int) {

   //sanity

   $int = (int)$int;

   if(!is_numeric($int)) return false;

   // You could internationalize here

   $suffixes = array('th', 'st', 'nd', 'rd');

   // Get the number in the tens place

   $tens = substr($int,-2,1);

   // All of the numbers 10-19 return 'th'

   if($tens == 1) return $int.$suffixes[0];

   // Get the number in the ones place

   $cardinal = substr($int,-1);

   // All numbers ending in 1, 2, 3 have special suffixes

   if($suffixes[$cardinal]) return $int.$suffixes[$cardinal];

   // All remaining numbers end in 'th'

Textile ol li count bug

will — Wed, 04 Feb 2009 20:10:41 +0000

Just hit a bug with the Textile 2.0 library:

# Portland, OR

# Sanford, FL

# Albuquerque, NM

# San Diego, CA

# Bellingham, WA

Was producing:

Portland, OR

Sanford, FL

Albuquerque, NM

San Diego, CA   

Bellingham, WA

Found the solution here:

You can work around the problem, by replacing these two lines (in the fList function in /textpattern/lib/classTextile.php):

foreach($text as $line) {
$nextline = next($text);

with:

foreach($text as $nr => $line) {
$nextline = isset($text[$nr+1]) ? $text[$nr+1] : false;

Counting Characters php vs javascript

will — Wed, 03 Dec 2008 04:13:05 +0000

On a recent project, an issue cropped up where we were exporting xml reports to a third party, who had rules about line lengths in Description fields.

So, I wrote up a quick-and-dirty character counter for the description field so the client can keep their descriptions under the 1500-word limit.

Here’s how it was done:

if (!$fdata['description']) {

   $errors[] = "You must enter a Description";

} elseif(strlen($fdata['description']) > 1500) {

   $len = strlen($fdata['description']);

   $errors[] = "Descriptions are limited to 1500 characters ($len)";

}

Now the html and javascript:

Description *
< ?= $ff['description'] ?>
1500 character limit

$(function(){

   $('#htmlarea').keyup(function(){

      var charLength = $(this).val().length;

      $('#desc_char_count').html(charLength + ' of 1500 characters used');

      if($(this).val().length > 1500) {

         $('#desc_char_count').removeClass('positive').addClass('negative').html('You have ' + $(this).val().length + ' characters. You may only have up to 1500 characters.');

      } else {

         $('#desc_char_count').addClass('positive').removeClass('negative');

      }

   });

   $('#htmlarea').keyup();

});

All was working well, except I underestimated the descriptions. The next morning, the thing was broken. The php side was kicking validation errors (“over 1500 characters”), while the javascript was counting a mere 1480. Why?

Turns out the data was full of bullets and other multibyte characters. To make the counts match, I needed multibyte-safe php:

if (!$fdata['description']) {

   $errors[] = "You must enter a Description";

} elseif(mb_strlen($fdata['description'],'UTF-8') > 1500) {

   $len = mb_strlen($fdata['description'],'UTF-8');

   $errors[] = "Descriptions are limited to 1500 characters ($len)";

}

Hooray! Now the counts match!
