html - Grab Selected Data using Select Box with PHP accessing a MySql database -

-

how grab selected data select box database? i've succeeded in doing radio button, when grabing select box stuck.

the theory is, if data in database saved 2007-2009 value in th_arsip field, show again selected data (2007-2009) , show options when want update data update form.

here's code:

<?php require "config.php"; $id_arsip = mysqli_real_escape_string($conn,$_get['id_arsip']); $sql      = "select * arsip id_arsip = '$id_arsip' "; $result   = mysqli_query($conn, $sql); $data     = mysqli_fetch_array($result); ?>  <div class="col-xs-4"><label>year</label> <select name="th_arsip" id="th_arsip" class="form-control" required> <?php echo "<option value='2004-2006' ".($data['th_arsip'] == "2004-2006"?'checked':'')."> 2004-2006 </option> ". "<option value='2007-2009' ".($data['th_arsip'] == "2007-2009"?'checked':'')."> 2007-2009 </option> ". "<option value='2010-2012' ".($data['th_arsip'] == "2010-2012"?'checked':'')."> 2010-2012 </option> ". "<option value='2013-2015' ".($data['th_arsip'] == "2013-2015"?'checked':'')."> 2013-2015 </option> ". "<option value='2016-2018' ".($data['th_arsip'] == "2016-2018"?'checked':'')."> 2016-2018 </option> ". "<option value='2019-2021' ".($data['th_arsip'] == "2019-2021"?'checked':'')."> 2019-2021 </option> "; ?> </select> </div>

any appreciated. thanks

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
