Collection of small improvements for contao.

• Allow HTML in headlines of content elements, news and calendar events.
• Allow long urls in content elements url fields. (normaly urls are limited to 255 characters)
• Rename articles of the same title as the page, if the page is renamed.
• Auto-Select the first text, checkbox, radio or select field in backend, if the edit mask is opened. (Improve speed of mass creating fields with keyboard shortcuts)
• Add insert tag {{page::*}} to access every field of the $objPage object.
• Add a lot of wrapper instert tags, for example {{base64_encode::*}}, see description below.

Wrapper insert tag

The wrapper insert tag is a flexible wrapper for other insert tags. The main syntax is {{<function>::<other insert tag>}}. <function> is a string expecting function, currently supported is:

• base64_encode
• base64_decode
• rawurldecode
• rawurlencode
• urldecode
• urlencode
• crc32
• crypt
• html_entity_decode
• htmlentities
• htmlspecialchars_decode
• htmlspecialchars
• lcfirst
• ltrim
• md5
• nl2br
• ord
• quoted_printable_decode
• quoted_printable_encode
• quotemeta
• rtrim
• sha1
• soundex
• str_rot13
• str_shuffle
• str_split
• str_word_count
• strip_tags
• stripcslashes
• stripslashes
• strlen
• strrev
• strtolower
• strtoupper
• trim
• ucfirst
• ucwords
• wordwrap
• standardize

<other insert tag> can be every other insert tag, including the wrapper insert tag itself (see Recursive example).

Example

{{urlencode::env::url}}

Recursive example

{{htmlentities::htmlspecialchars::insert_article::123}}

Embedded example

<a href="{{link_url::123}}" rel="{{htmlspecialchars::strip_tags::insert_content::456}}">read more...</a>

Extending with custom wrapper functions

Everyone can extend the wrapper insert tag by adding a custom function to $GLOBALS['TL_INSERTTAG_WRAPPER'].

$GLOBALS['TL_INSERTTAG_WRAPPER'][] = 'customFunction';

The wrapper can only pass one parameter to the function, the result of the wrapped insert tag.
