Solved - Collecting date as attribute, Preg match rule conflicts with process flow?

[rrzakirov]

Prior - I may have set'Attribute identifier' wrongly as delivery_date... - this is bot chat I am talking about, and I am using LHC 4.52; so here is the problem:

I have chosen 'Collect custom attribute' in trigger, and used /^(0[1-9]|[12][0-9]|3[01]).(0[1-9]|1[0-2]).(\d{4})$/ as Preg match rule. Now when visitor inputs the date as DD.MM.YYY within the allowed period, or if I symplify the rule and let visitor response with any date, chat returns 'Your message does not match required format!' message from bot.

error_log complains:
[19-Jan-2025 12:00:08 Asia/Ashgabat] PHP Warning: preg_match(): Unknown modifier '^' in /home/patmayur/sohbet.3-damja.net/lib/core/lhgenericbot/lhgenericbotworkflow.php on line 869, not recognizing '^' as modifier;

And lhgenericbotworkflow.php 869 line is as:

869 } else if (isset($eventData['content']['preg_match']) && !empty($eventData['content']['preg_match']) && $eventData['content']['preg_match'] != 'validate_email' && !preg_match('/' . $eventData['content']['preg_match'] . '/',$payload)) { // Preg match validation
870 $invalidMessage = true;

Hopefully, anyone will suggest?

You see in the code i already wrap with slashes...

Labas dienas, Remigijus!

Do you mean I have to remove opening and closing slashes? I tried, nothing changed. I am not coder, sorry!

[remdex]

Yes, you had to remove slahes if nothing changed, your rule just invalid looks like.

Got that rule from the bot on https://doc.livehelperchat.com/docs/bot/collect-custom-attribute

Remigijus, it was the rule! Thank you. I changed it to ^(0[1-9]|[12][0-9]|3[01]).(07|08|09|10).(19|20)\d{2}$ (the one that didn't work was ^(0[1-9]|[12][0-9]|3[01]).(0[1-9]|1[0-2]).(\d{4})$). It works well now.
