The text helper contains functions useful when working with text, apart from validation.

Loading the Helper

$th = Loader::helper(‘text’);

Methods

$r = $th->sanitizeFileSystem($text, $leaveSlashes=false)

$text = $th->sanitize($text, $maxlength = 0)

Strips tags and optionally reduces string to specified length.

$text = $th->entities($text)

Runs htmlentities on $text, but uses the built-in concrete5 APP_CHARSET constant.

$text = $th->shorten($text, $numChars = 255, $tail = ‘…’)

Like sanitize, but requiring a certain number characters, and assuming a tail

$text = $th->camelcase($text)

Takes a string and turns it into the CamelCase or StudlyCaps version.

$text = $th->autolink($text, $newWindow = 0)

Automatically add hyperlinks to any twitter style @usernames in a string.
