I am working on an Asset Database problem. I receive $id from $_GET["id"]; I then query the database and display the results.
This works if my id is an integer like "93650" but if it has other characters like "wci1001", it displays this MySQL error:
Unknown column 'text' in 'where clause'
All fields in tables are of type: VARCHAR(50)
What would I need to do to be able to use this query to search by id that includes other characters?
Thank you.
