Having trouble updating database using php

Question

I have a database called specials with a table called specials, the table has 6 rows, there are 3 records a record with an id of 1,2, and 3. One of the rows is called title. I have data already there but I want to update the data using a form. How ever my mysqli_query is not working.

Here is my code.

mysqli_query($connect, "UPDATE specials SET title=san diego WHERE id='1'");

corrected:- UPDATE specials SET title='san diego' WHERE id='1' — Ramesh_D, May 30 '14 at 05:14

Assuming title is varchar and id is int

mysqli_query($connect, "UPDATE specials SET title='san diego' WHERE id=1");

you are inserting a string in varchar field so it should be quoted also try

mysqli_query($connect, "UPDATE specials SET title='san diego' WHERE id=1");

if datatype is varchar string should be quoted like title='san diego'

if int no need to quote (but you can use with quote) id = 1
