The tag stripping made Twitter posts look terrible, so I changed the code. I'd love to see you guys do this in the next release so I don't have to keep replacing the code
In short - change paragraph and break tags to newlines BEFORE stripping tags. This makes formatting correct.
// Replace the {introtext} tag
if (EBString::stristr($content, '{introtext}') !== false) {
$search[] = '{introtext}';
// Don't strip tags, so we can put newlines in for <p> and <br> elements first
$introText = $post->getIntro();
$introText = str_ireplace("<p>", "\n\n", $introText);
$introText = str_ireplace("<br>", "\n", $introText);
$introText = str_ireplace("<br/>", "\n", $introText);
$introText = str_ireplace("<br />", "\n", $introText);
// Now we can strip the tags, which will clean up the text
$introText = EBString::substr(strip_tags($introText), 0, 230) . JText::_('COM_EASYBLOG_ELLIPSES');
$replace[] = $introText;
}
