php add time slot into mysql - php

Question

I have the following coding and would like to insert a sql into mysql but I got the following error :
"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1"**
<?php
date_default_timezone_set('Hongkong');
include('fun.php');
$outlet="Da Da";
$officehrStr = "11:00"; // morning
$officehrEnd = "02:00"; // midnight
if (isset($_POST['confirm'])) {
$dt1=new DateTime($officehrStr);
$dt2=new DateTime($officehrEnd);
$values=array();
while ($dt1 <= $dt2) {
$values[]="('". $outlet ."','". $dt1->format('H:i') ."')";
$dt1->modify("+".$_POST['slot']." minute");
}
include('db.php');
$sql="INSERT INTO tb_timeslot (outlet,timeslot) VALUES ". implode(',',$values);
mysql_query($sql) or die(mysql_error());
mysql_close($conn);
?>

Answer 1

If this is SQL syntax error, my guess is a problem with this line
$sql="INSERT INTO tb_timeslot (outlet,timeslot) VALUES ". implode(',',$values);
Try to change it with this
$sql="INSERT INTO tb_timeslot (outlet,timeslot) VALUES (". implode(',',$values).");";

Answer 2

the problem get solved by adding the following coding "$dt2->add(new DateInterval('PT86400S')); " between $dt2=new DateTime($officehrEnd); and while ($dt1 <= $dt2) {" Thank you for all your valuable time

Please have a look in your sql statement.
$sql="INSERT INTO tb_timeslot (outlet,timeslot) VALUES (". implode(',',$values).");";
You can see that you are trying to insert data in two columns (outlet,timeslot) but assigning values to inly 1 column. You must assign 2 values like.
$sql="INSERT INTO tb_timeslot (outlet,timeslot) VALUES (". implode(',',$values).", '$replace_variable_name');";
Please update your statement with my statement but don't forget to edit "replace_variable_name" with your defined value.
Hope this will help you.
