c_datetime.php

<input type='text' class="form-control" name="datee" /> <input type='text' name="timee" class="form-control" />

can please tell how resolve issue?

you have error in part. see errors error_reporting(e_all);

<?php     if(isset($_post['save']))// added isset.         {             $datee = mysqli_real_escape_string($con, $_post['datee']);             $timee = mysqli_real_escape_string($con, $_post['timee']);             echo $datee;             echo $timee;         } ?>

what $con?? if connection object, have missed include() in code.

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
