Below is a collection of examples of different ways keyword modifiers can be used. If you have a handy keyword modifier you would like to add to the list, be sure to let us know.

Word play

Print ellipsis symbol if a block of text exceeds maximum number of words or characters

//max characters
%asset_metadata_description^maxchars:20^trim%%asset_metadata_description^charcount^gt:20:…:%
 
//max words
%asset_metadata_description^maxwords:5^trim%%asset_metadata_description^wordcount^gt:5:…:%

Max charcount result: The quick brown fox jumped over the lazy dog => The quick brown fox…

Max wordcount result: The quick brown fox jumped over the lazy dog => The quick brown fox jumped…

Print a semicolon separated list from a matrix value (such as checkbox, select field, multiple text metadata fields) into a ordered or un-ordered list, but only if it is not empty

%asset_metadata_keywords^replace:;:</li><li>^tagif:li^tagif:ul%

Original: Value 1; Value 2; Value 3

Result: <ul><li>Value 1</li><li>Value 2</li><li>Value 3</li></ul>

Number play

Calculate 10% GST of a product price and price without GST

//GST
%item_price^number_format:2^divide:11^number_format:2%
//price excluding GST
%item_price^number_format:2^divide:11^multiply:10^number_format:2%

GST result: 110.00 => 10.00

Price excluding GST result: 110.00 => 100.00

Simple padding

Pad to two digits: Adds an extra '0' in front if the number is only one digit.

%asset_metadata_number^charcount^eq:1:0:%%asset_metadata_number%

Regular Expression Replacements

Print the file extension of any file asset

%asset_name^replace:.*\.: %

Result: document.pdf => pdf

Extract any parameter value from a URL

%asset_metadata_youtube^replace:.*v=:^replace:&.*:%

Result: http://www.youtube.com/watch?v=5B-Es5-CjFg&feature=youtube_gdata => 5B-Es5-CjFg

Print the page number outside of an asset listing, conditionally

%globals_server_QUERY_STRING^contains:_result_page:Page : %%globals_server_QUERY_STRING^replace:.*_result_page=:^replace:&.*:%

Result: http://www.squiz.net/asset-listing?result_15168_result_page=2 => Page 2

Escape percentages from keyword value

%asset_name^replace:25:TW3NTYF1V3^urlencode^replace:.25:%^urldecode^replace:TW3NTYF1V3:25%

Result: %some_matrix_keyword% => %some_matrix_keyword%

Replace all white space occurrences (including new lines) with a single space

%asset_metadata_description^replace:\s: %

Result: Some description
with line break => Some description with line break .

Or, to condense all white space:

%asset_metadata_description^replace:\s+: %

Strip HTML but retain spaces between paragraphs and line breaks

% asset_metadata_description^replace:(<\/p>|<br\/?>):\1 ^striphtml%

Result: Line 1.
Line 2. => Line 1. Line 2. . If necessary, cater for other elements like h[1-6]

Print your site path without the domain

<MySource_PRINT id_name="__global__" var="current_asset" keyword="asset_url^replace:((.)*\.\D{2,3}):/" />

This will take all characters up until it reaches a period character, followed by characters of length 2 to 3 ( .com.au , .net , etc) and replace them with the / character. Please note that if any of your webpages contain a period in the page directory (such as /example.page/ ), this will not work.

Result: http://www.example.com.au/newpage/test-page => /newpage/test-page

Print a schema relative path for an asset URL

%globals_asset_url^replace:.*\/\/://%

Result https://www.site.com/page => //www.site.com/page

Remove certain parts of a URL (including colon)

This trick uses the hexadecimal representation of a character, in this case colon: "\x3A".

First group matches "http://" or "https://". Second group matches everything after the domain (first slash).

%asset_url^replace:(https?\x3A\/\/)|(\/.*):%

Using colon in a time stamp

Instead of having a separate keyword replacement for each part of the date format, use a different divider (eg =), then replace the url-encoded value.

%globals_asset_created^date_format:H=i=s^urlencode^replace:3D:3A^urldecode%

Using colon in ^eq:: return value

Uses the base64 value for colon (Og==).

%globals_asset_assetid^neq:1:Og==^base64decode% 

Return the first or last word (even if hyphenated) from a string

%asset_name%                   ==>  John-Paul Syriatowicz
%asset_name^replace:(\s).*$:%  ==>  John-Paul
%asset_name^replace:.*(\s):%   ==>  Syriatowicz

Remove the last or first character of a string

%asset_name%                               ==>  ABC
%asset_name^replace:.$:%                   ==>  AB
%asset_name^reverse^replace:.$:^reverse%   ==>  BC

Miscellaneous

Print different asset value depending on asset type (parse file example)

<MySource_PRINT var="asset_type^replace_keywords:contains:Redirect:{redirect_url}:{asset_url}" />

Redirect pages will print redirect_url keyword value.

All other pages will print asset_url keyword value.

List out current asset contents with it’s own paint layout

When using %asset_contents% keyword replacement in an asset listing, be sure to use the following to ensure it is painted with it’s own paint layout:

% asset_assetid^as_asset:asset_contents%

Output 'checked="checked"' if asset ID is in a comma-separated list of IDs

This one his handy if you need to store multiple asset IDs in a single metadata field, and then spit them out in a form

% globals_user_metadata_feed_subscriptions^replace_keywords:replace:.*\b{asset_assetid}\b.*:\1^replace_keywords:eq:{asset_assetid}:checked="checked"%

Use metadata of homepage if current page metadata is empty

Use case: Custom background images on children pages which are different to the home page. If not custom image set, use the homepage image.

%globals_asset_metadata_setting.background.image^as_asset:asset_url^replace_keywords:empty:{globals_site_index_id^as_asset:asset_metadata_setting.background.image^as_asset:asset_url}%

Get current URL

If %globals_asset_url% isn't what you want, try one of:

%globals_site_url%
// these may change behaviour based on server configuration
%globals_server_HTTPS^eq:on:https:http%://%globals_server_HTTP_HOST%%globals_server_REQUEST_URI%
%globals_server_HTTPS^eq:on:https:http%://%globals_server_SERVER_NAME%%globals_server_REQUEST_URI% 

Print dynamic value depending on if you are on the homepage or not

//Up to version 5.4.2.2:
%globals_asset_assetid^replace:{globals_site_assetid}|{globals_site_index_id}:H^eq:H:home:inside%

//From version 5.4.3.0 and up:
%frontend_asset_is_homepage^eq:1:home:inside%

Change the name of the commit button on Asset Builders

Change "Commit" to whatever the commit button's value is in your system.

%commit_button_clean^replace:Commit:Submit Comment%
