Subscription Widget exception errors under PHP 7.3
-
I guess we will have to update to MailPoet 3 now, once we resolve a conflict with one other plugin (WP Cassify). Here is the error that MailPoet 2 generates with every page load that has the embedded MailPoet Subscription Form widget under PHP 7.3 and WordPress 5.2.
Exception: Uncaught exception ‘Exception’ with message ‘Template ‘templates/form/web/widgets/#type.html’ not found !’ in wp-content/plugins/wysija-newsletters/helpers/render_engine.php:723

Yes, this error only shows up when you include widget code on a given page. Didn’t think it was Mailpoet-2 at first as the plugin worked fine on another 7.3 site – but that site doesn’t display the subscribe widget.
Did you happen to pinpoint the code problem? Not sure why it’s feeding it ‘#type.html’ as the file? :
foreach($this->_template_path as $path) { if ($template && file_exists ("$path/$template")) { $file = "$path/$template"; return $this->_loadFile ($file); } } throw new Exception ("Template '$template' not found !"); return false;$template = “#type.html”?
PHP Fatal error: Uncaught Exception: Template 'templates/form/web/widgets/#type.html' not found !
Hmmm.I also get a compilation warning apparently before this error each time – not sure if related. Error on some PCRE here:
if (preg_match ("'".self::_VAR.self::_MODIFIER."'", $value, $is_var)) {
(^note – I replaced the 2 backtick characters with single-quotes as the forum editor switches code display on off.Log entry: “PHP Warning: preg_match(): Compilation failed: invalid range in character class at offset 11”

Fixed/Solved entire problem – it was the
preg_matchas noted above:LINE 43: /wp-content/plugins/wysija-newsletters/helpers/render_engine.php
Look for the “w-” (column 30)-
Original code:
const _VAR = '([\$#])([\w-_\.]+)';Add a back slash “\” before the “-”
Updated code:
const _VAR = '([\$#])([\w\-_\.]+)';In php 7.3
preg_matchneeds the dash (“-“) escaped.My widget now works as well.
No more fatal error exceptions (nor warnings). -
