    Unless specifically mentioned in your add-on's documentation, all code must be compatible with PHP version 4.3+. Additionally, do not use PHP functions that require non-default libraries to be installed unless your code contains an alternative method when the function is not available, or you implicitly document that your add-on requires said PHP libraries.

    Use of $SESS->cache

    -
    -

    $SESS->cache is an array provided for you to use for "flash" content, i.e. values that you would like to persist during a page load, helping you eliminate redundant queries and PHP processing. To avoid conflicts with other first and third-party use of this array, always access it as a multi-dimensional array, using your class name as the primary array name, and your variables within. Naming conventions should follow that of other variables: lowercase letters, underscores for separators between words, and meaningful names.

    Here is an example of how one might utilize the $SESS->cache array. This way, no matter how many times this method is called on a given page load (for instance, a tag being used twice on a template, or within a tag that might loop, such as a plugin within the Weblog entries tag), the query and loading of the array occurs only once.

    - -if ( ! isset($SESS->cache['super_class']['admins'])) -{ - $query = $DB->query("SELECT member_id FROM exp_super_class_admins"); - - if ($query->num_rows > 0) - { - foreach ($query->result as $row) - { - $SESS->cache['super_class']['admins'][] = $row['member_id']; - } - } -} - -// set a local variable from the cached global so it's easy to use in the code -$admins = $SESS->cache['super_class']['admins']; - -

    You can see an example of real-world usage of $SESS->cache in the Weblog module's fetch_custom_weblog_fields() and next_prev_entry() methods, and the IP to Nation module's get_country() method.
