MySQL query boolean given [duplicate]

Answer 1

http://php.net/manual/en/function.mysql-query.php

mysql_query returns false on error, you should check the return value.

Add this to the code after the query:

if (!$query) {
    trigger_error('Invalid query: ' . mysql_error());
}

Answer 2

This stems from the previous line:

$query = mysql_query("SELECT * FROM archive");

Since you are working with a procedural API, you (should) pass in the MySQL connection resource that you want to perform the query on.

Because a) you did not pass in the connection resource OR b) the query itself failed, mysql_query just returned FALSE, hence the error message:

mysql_fetch_array() expects parameter 1 to be resource, boolean given

Change the above to this and you should be all set assuming $db is the return value of mysql_connect:

$query  = "SELECT * FROM archive";
$result = mysql_query($query, $db);
if(!$query) {
   trigger_error(mysql_error()." in ".$query);
}
