{
echo"
{date: ".$listele['tarih'].", value: 'rezerve'}";

Console error line is; consol error line

Answer 1

Comma (s) is missing

var data = [ <?php
  foreach ($db->query("SELECT * FROM ev_uygunluk where evid='{$evid}' order by id ASC") as $listele) 
{
echo "{date: new Date('".$listele['tarih']."'), value: 'rezerve'}, ";  // this comma !
}
  ?> ];

Answer 2

You're having double quotes wrongly placed inside your brackets and your objects aren't separated correctly with commas. Try this instead:

<?php
$tmp = [];
foreach($db->query("SELECT * FROM ev_uygunluk where evid='{$evid}' order by id ASC") as $listele) {
    $tmp[] = "{date: '{$listele['tarih']}', value: 'rezerve'}";
}


echo "var data = [".implode(', ', $tmp)."]";

Answer 3

you should have use es6 back tick `` to avoid this type of mistake

var data = [ <?php foreach ($db->query("SELECT * FROM ev_uygunluk where evid='{$evid}' order by id ASC") as $listele) { echo" {date: ".$listele['tarih'].", value: 'rezerve'}"; } ?> <?php foreach ($db->query("SELECT * FROM ev_uygunluk where evid='{$evid}' order by id ASC") as $listele) { echo" {date: ".$listele['tarih'].", value: 'rezerve'}"; } ?> ];

I have used backtick but code editor not displaying it use before <? and at after the end ?> before <? and at after the end ?> Hope this will solve your issue.
