Question

The Code:

        $query = "SELECT * FROM tweets WHERE read=n";
        $result = mysqli_query($mysqli,$query);

        $row = mysqli_fetch_array($result, MYSQLI_ASSOC);
        echo $row["from_user"], $row["text"];

The above code gives me this:

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in /index.php on line 16 

The below code does not:

        $query = "SELECT * FROM tweets";
        $result = mysqli_query($mysqli,$query);

        $row = mysqli_fetch_array($result, MYSQLI_ASSOC);
        echo $row["from_user"], $row["text"];

The “read” field is ENUM(‘y’,’n’).

Answer 1

read is a reserved keyword in MySQL. As it’s the name of your column, add backticks surrounding the word in your WHERE clause and that should fix the issue:

SELECT * FROM tweets WHERE `read` = 'n';
