requinix Posted March 16, 2012 Share Posted March 16, 2012 if ($query = mysqli_prepare($conn, "SELECT FirstName, LastName, Age, Hometown, Job FROM people WHERE age With prepared statements you don't stick the values right into the query. For mysqli substitute the variable with a question mark. No quotes, even for strings. Speaking of quotes, don't use quotes for numbers. Prepared statement or not. [code=php:0] if ($query = mysqli_prepare($conn, "SELECT FirstName, LastName, Age, Hometown, Job FROM people WHERE age Quote Link to comment Share on other sites More sharing options...
