squaredesign short codes: pain free magic

Upload/Insert

and the PHP to make it happen...

An opening/closing Short Code

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

[pullquote]velit esse cillum dolore eu fugiat nulla sint non culpa[/pullquote] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.Ut enim ad minim veniam, quis nostrud...

Theme Functions (functions.php)<?php

?>add content to the output...

add_shortcode('pullquote','makePullQuote');

PHP for opening/closing Short Code

function makePullQuote($attributes, $contents) { return '<div class="pullquote">' . $contents . "</div>";}

Theme Functions (functions.php)<?php

?>the result...

add_shortcode('pullquote','makePullQuote');

PHP for opening/closing Short Code

function makePullQuote($attributes, $contents) { return "<div class=\" pullquote \">" . $contents . "</div>";}

squaredesign short codes: pain free magic

The Results!

looks quite a bit like Kubrick

<div class="pullquote">velit esse cillum dolore eu fugiat nulla sint non culpa

</div>

squaredesign short codes: pain free magic

we’ll use Short Code Attributes

Revisions!

Upload/Insert

our PHP code gets the Attributes...

Short Code with Attributes

[pullquote side='left']sunt in culpa qui officia deserunt[/pullquote]Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua...

[pullquote side='right']velit esse cillum dolore eu fugiat nulla sint non culpa[/pullquote]Lorem ipsum dolor sit amet.Ut enim ad minim veniam...

squaredesign short codes: pain free magic

Theme Functions (functions.php)<?php

?>let’s do something with the Attributes...

the PHP function, using Attributes

add_shortcode('pullquote','makePullQuote');

function makePullQuote($attributes, $contents) { $align = $attributes[‘side’]; return “<div class=\" pullquote $align \">” . $contents . "</div>";}

Theme Functions (functions.php)<?php

?>now one left, one right...

the PHP function, using Attributes

add_shortcode('pullquote','makePullQuote');

function makePullQuote($attributes, $contents) { $align = $attributes[‘side’]; return “<div class=\" pullquote $align \">” . $contents . "</div>";}

squaredesign short codes: pain free magic

The Results!

looks quite a bit like Kubrick

<div class="pullquote right">velit esse cillum dolore eu fugiat nulla sint non culpa

</div>

<div class="pullquote left">sunt in culpa qui officia deserunt

</div>
