Deskripsi
A series of shortcodes for using custom field values in pages or posts (or in sidebar widgets – via Section Widget!), which would then allows you to take store the actual data in custom fields while storing the presentation in the page/post body. This transforms WordPress into an awesome CMS. Keep reading for more inspirations.
Basic Usage
</code></pre> <p>Example:</p> <pre><code>Picture of the day: <img src='[cf "picture-link"]' /> </code></pre> <p>This would output something like <code><img src='http://thesite.com/something.jpg' /></code>, assume the post/page has the custom field "picture-link" and its value is "http://thesite.com/something.jpg". That way, you (or your clients!) would never accidentally take out a div when updating your page because you won't have to touch the page/post body anymore!</p> <h4>Default Values</h4> <pre><code>[cf "custom field name" default="display this if the CF is undefined"] </code></pre> <p>Example:</p> <pre><code>Contact [cf "support-email" default="support@mycompany.com"] if you have questions. </code></pre> <p>support@mycompany.com will be displayed there if the custom field "support-email" is not present in that post/page.</p> <h4>Simple Template</h4> <pre><code>[cf "custom field name" default="default value"]...template...Example:
Price:
USD$%value%If you cannot use
%value%
as your placeholder text for some reason, you can change it by specifying the placeholder attribute.Example:
Price:
USD$__value__Multiple Values
It’s smart enough to do the right thing. If your post has the following custom fields:
- concert-date: Jan 14th
- concert-date: Jan 28th
- concert-date: Feb 2nd
Then
</code> will output <code>Jan 14th,Jan 28th,Feb2nd</code>, exactly what you would expect. You can also optionally provide a separator to replace the default (,).</p> <p>Example:</p> <pre><code>Come to one of our concerts on the following dates: [cf "concert-date" separator=" / "] </code></pre> <p>(=> Jan 14th / Jan 28th / Feb 2nd)</p> <h4>Sorting</h4> <pre><code>[cf "custom field name" sort="nosort|asc|dsc|random" type="string|int|integer|float|bool|boolean|date|auto"] </code></pre> <p>You can control how it sort the items (when there's more than one) using the sort attribute (default is <code>nosort</code>). By default, it would compare them using PHP's comparison operator (i.e. try to cast them into numeric values, or compare them as strings if that failed). However, you can force a type cast by specifying the type attribute (default is <code>auto</code>).</p> <h4>Display Single Value</h4> <p>If display multiple values is not what you want it to do, you can use <code>[cf single="true"]</code> to force it to display only the first value. Combining what we have learned so far, you can display a single random value by <code>[cf single="true" sort="random"]</code>.</p> <h4>Summary</h4> <p>Syntax for <code>[cf]</code> shortcode: (default values in parenthesis)</p> <pre><code>[cf "field-name" default="" placeholder="%value%" single="(false)|true" separator="," sort="(nosort)|asc|dsc|random" type="string|int|integer|float|bool|boolean|date|(auto)"](OPTIONAL) template
Conditionals
Conditionals tags is what makes this plugin unique. Here is a list of them:
[if-cf-def "custom field name"]
Do this when "custom field name" is defined for this page/post
[/if-cf-def]
[if-cf-ndef "custom field name"]
Do this when "custom field name" is NOT defined for this page/post
[/if-cf-ndef]
[if-cf-eq "custom field name" "value"]
Do this when "custom field name" == "value"
[/if-cf-eq]
[if-cf-neq "custom field name" "value"]
Do this when "custom field name" != "value"
[/if-cf-neq]
[if-cf-lt "custom field name" "value"]
Do this when "custom field name" < "value"
[/if-cf-lt]
[if-cf-gt "custom field name" "value"]
Do this when "custom field name" > "value"
[/if-cf-gt]
[if-cf-let "custom field name" "value"]
Do this when "custom field name" <= "value"
[/if-cf-let]
[if-cf-get "custom field name" "value"]
Do this when "custom field name" >= "value"
[/if-cf-get]
More detailed documentations will be published soon. In the mean time, check out the following examples and the comments in the PHP code to get a rough idea.
Examples
[if-cf-get "deadline" "today" type="date"] Submit your application <a href='
'>here</a>. [/if-cf-get] [if-cf-lt "deadline" "today" type="date"] Sorry we regret that we cannot take anymore applications. [/if-cf-lt] [if-cf-def "discounted-price" "discount-expires" logic="and"] This product is on discount, get it now for [cf "discounted-price" /] [cf "discount-expires" default="for a limited time"]before %value%!
[/if-cf-def]
Please note: It seems that there is a serious bug in WordPress’ shortcode parser that prevents shortcodes from functioning correctly in certain occasions. The developers are hard at work to get this fixed before the 2.8.3 release. (See #10082) Therefore, please do not report any parser related bugs for the moment. (e.g. the shortcode is displayed on the actual page)
