[Plugin: Page.ly MultiEdit] Minor Errors

Hi !!
I was having the same 2 issues.
For the php errors, I fidex it this way (I did only want the plugin on pages, anyway you can’t use templates on posts without plugins I think):
1. I check to see if the post is a page (I only got the errors on posts)
2. If it is a page I use the plugin
3. If not, I do nothing.
This prevents errors, here is the code I changed for the function doMultiMeta() fonction. Not super clean, but works for me ^^
+ the your display hiddent trick ^^

For the mce bug, it’s a conflict with tinymce. Mine was different, I got some mce_href tags for images and links which made my code note w3c valid. I found a regex posted by a guy here (yeah joomla forum but the regex works fine) and changed the pagely function multieditDisplay($index) function to this to remove the tags froms templates:

// api for templates
function multieditDisplay($index) {
	if ($GLOBALS['multiEditDisplay'] === false) {
		$GLOBALS['multiEditDisplay'] = get_post_custom(0);
	}
	$index = "multiedit_$index";
	if (isset($GLOBALS['multiEditDisplay'][$index])) {
  // stéphanie bugfix1: fixing the mce_ (adds mce_href code to new tabs) issue with a regex yeah !!
	$str = $GLOBALS['multiEditDisplay'][$index][0];
	$str = preg_replace( '#mce_[a-z]+="[^"]+"#', '', $str );
	echo $str;
	}
}

Maybe you could try something similar ?
