How should I go about removing periods (and preferably empty trailing spaces as well) with the CI url_title() helper function? Below is the CI helper function code. Also, shouldn't I create my own helper rather than modify the system one? I have seen references to this, but have yet to extend or modify core files. I will have to look up this, if so. Thanks!!
Code:
// ------------------------------------------------------------------------
/**
* Create URL Title
*
* Takes a "title" string as input and creates a
* human-friendly URL string with either a dash
* or an underscore as the word separator.
*
* @access public
* @param string the string
* @param string the separator: dash, or underscore
* @return string
*/
if ( ! function_exists('url_title'))
{
function url_title($str, $separator = 'dash')
{
if ($separator == 'dash')
{
$search = '_';
$replace = '-';
}
else
{
$search = '-';
$replace = '_';
}
$trans = array(
'&\#\d+?;' => '',
'&\S+?;' => '',
'\s+' => $replace,
'[^a-z0-9\-\._]' => '',
$replace.'+' => $replace,
$replace.'$' => $replace,
'^'.$replace => $replace
);
$str = strip_tags($str);
foreach ($trans as $key => $val)
{
$str = preg_replace("#".$key."#i", $val, $str);
}
return trim(stripslashes($str));
}
}
