Okay I need to make a HTTP post and on submit go to the url: Basically I need to replicate this: (which works fine as standard HTML)
{input type="hidden" name="token" value="b408035a727983360a3196bb00f3bc403b876773"}
{input type="hidden" name="direct" value="true"}
Domain: {input type="text" name="domain"}
{select name="ext"}
{option}.com{/option}
{option}.co{/option}
{option}.net{/option}
{option}.co.nz{/option}
{/select}
{input title="submit" onclick="this.form.method='post'; this.form.action='https://www.mysite.co/checker.php';this.form.submit();" type="submit"}
