<p>How to write the replacement value for a new custom XBBCode tag:</p>
<h3>Static text:</h3>
<p>Simply enter the HTML code that should replace [tag=option]content[/tag]. The following variables are available to you:</p>
<ul>
<li>{option} will be replaced with the value of 'option' in the above example</li>
<li>{content} will be replaced with the text between the text.</li>
</ul>
<h3>Multiple arguments:</h3>
<p>Your tag can take advantage of multiple arguments that can be provided in the form of [tag arg1=value1 arg2='value 2']content[/tag].
In this example, you will have access to these variables:</p>
<ul>
<li>{arg1} will be replaced with val1,</li>
<li>{arg2} will be replaced with val2,</li>
<li>{content} remains the same.</li>
</ul>
<h3>PHP Code</h3>
<p>Enter the PHP code (without <?php ?>) that should be executed. Variables are 'filtered' into the code as literal strings prior to execution, so they should be wrapped in quotes and assigned to variables.</p>
<p>As an example, [php=label]link text[/php] might be replaced by this code:</p>
<code>
<?php
echo check_plain('
echo "<label>{option}</label><code>";
echo highlight_string("{content}");
echo "</code>"
');
?>
</code>
<p>You may return your replacement code by printing it or using return.</p>
