Creating a very simple shortcode solution in PHP-CodePudding

I want to construct a very basic shortcode solution in a simple non-WordPress website I am maintaining, to allow users to enter content that will be pulled from a database and rendered to screen, allowing them to create a href buttons.

I've seen various classes for this but want to do this in just a line or two of code if possible.

Only they will enter via a shortcode with this format:

[BUTTON link="www.test.com" label="Click here"]

So far I have this which doesn't extract the attributes properly:

$copy=preg_replace('/\[(BUTTON )(.*?)\]/', '<a href="$2">$1</a>', $copy);

Can anyone advise?

CodePudding user response：

maybe check how WordPress implemented it?

CodePudding user response：

I assume that you don't actually want to capture the BUTTON, but the link and the label.

Code: (Demo)

echo preg_replace(
         '/\[button link="([^"] )" label="([^"] )"]/i',
         '<a href="$1">$2</a>',
         $text
     );
