How Can I Verify store code in mysql and update the table if result return true

Question

Someone should please help me verify whether this code is right. I want to generate ID base on Pin from pin table under Pin column and insert into pin table in the appid column.

Answer 1

just try to write your query some thing like this with providing escape character ( ` ) to your field name.

mysql_query("UPDATE pin SET 'appid' ='$num' WHERE 'Pin' = '$Pin'");
