如何使用爆破数组更新mysql

Question

I am working on a form with multiple checkboxes. the value of checkboxes is stored in the mysql database and and INSERT query is working fine when i try to update record with UPDATE query something went wrong i have this index.php

This is my insert query which is working fine

$hobi=implode(',',$_POST['hobi']);

$db->query("INSERT INTO info (cekbox) VALUES('$hobi')");

And this is my update query which is not working means not updating records

$hobi=implode(',',$_POST['hobi']);

//$db->query("INSERT INTO info (cekbox) VALUES('$hobi')");

$db->query("UPDATE info (cekbox) WHERE id= '$id' SET VALUES ('$hobi') ");

Please tell me how to put implode array in update query?

Answer 1

You got your update statement wrong. This has nothing to do with the implode() .

$db->query("UPDATE info SET cekbox='$hobi' WHERE id= '$id'");

Answer 2

不要将UPDATE查询视为INSERT查询

$db->query("UPDATE `info` SET `cekbox`='".$hobi."' WHERE `id`= $id"); 

Answer 3

your update sql is incorrect:

UPDATE info (cekbox) WHERE id= '$id' SET VALUES ('$hobi')
// should be:
UPDATE info SET cekbox = '$hobi' WHERE id= '$id';
