How to Fix: Increment value in MySQL update query

MySQL update query issue with incrementing points.

Quick Answer: The problem lies in the way you're concatenating strings. Use prepared statements or parameterized queries to avoid SQL injection and ensure correct formatting.

To increment the value in a MySQL update query, you need to use the correct syntax for adding integers. The problem with your code is that you're using single quotes around the $points variable, which is causing it to be treated as a string instead of an integer.

🛠️ Step-by-Step Verified Fixes

Method 1: Using Integer Literal

  1. Step 1: Replace the single quotes around $points with a comma (,) to separate it from the +1.

Method 2: Using Integer Arithmetic Operator

  1. Step 1: Use the + operator to increment the value of $points.

Example: `mysql_query('UPDATE member_profile SET points = '.($points+1).' WHERE user_id ='.$userid);
