str_replace?

[sheppardzwc]

Trying to design a plugin for my site...

Basically I want, when someone says /kumquat <a username>, (old joke, don't ask) that it will show:

<username> throws a kumquat at <username printed after /kumquat>.

The code I've done is this:

PHP Code:

<?xml version="1.0" encoding="ISO-8859-1"?>

<plugins>
    <plugin active="1" executionorder="5" product="vbulletin">
        <title>/KUMQUAT by toontownhall.com</title>
        <hookname>postbit_display_complete</hookname>
        <phpcode><![CDATA[$post['message'] = str_replace('/kumquat ', $post[postusername], "throws a kumquat at", $post[message]);]]></phpcode>
    </plugin>
</plugins>

But of course that doesn't seem to work. Any ideas?
