function domain_lookup_simple in Domain Access 7.3

Same name and namespace in other branches

1. 6.2 domain.module \domain_lookup_simple()
2. 7.2 domain.module \domain_lookup_simple()

Determines the domain matching the given hostname.

This function runs a lookup against the {domain} table matching the subdomain column against the given parameter $_name. If a match is found the function returns an array containing the domain requested and the matching domain_id from the {domain} table.

If no match is found domain_id is set to 0 for the default domain.

During the process hook_domain_bootstrap_lookup() is invoked to allow other modules to modify that result.

Parameters

$name: The string representation of a {domain} entry.

$reset: Set TRUE to ignore cached versions and look the name up again. Optional.

Return value

An array containing a domain_id from {domain} matching the given domain name
