Arrays and Hashes

EXAMPLE ARRAY:

<cms:set populated_authors__array = '
{
    "26b3eed025edc2ef22a0466bab45ae57" : {
        "page_id" : "18",
        "name" : "Ray Bradbury"
    },
    "60ee1ca285beb8348406446e56e6cda4" : {
        "page_id" : "19",
        "name" : "Isaac Asimov"
    }
}
' is_json='1' scope='global' />


-- Variable '_input_author_hash' comes from CSV_READER and I create a hash of it to avoid string comparison

<cms:set _input_author_hash = "<cms:md5 _input_author />" scope='global' />

-- Next, we check if that hash is already in my list of Authors in CMS

<cms:if "<cms:arr_key_exists key=_input_author_hash in=populated_authors__array />" >

    -- Author already populated and stored in array, thus I know its k_page_id -->

      <cms:set related_author_id = "<cms:get "populated_authors__array.<cms:show _input_author_hash />.page_id" />" />


-- Otherwise add a new Author to the list:
<cms:else />

    -- creates a new page with this Author

      <cms:db_persist _masterpage='related_authors.php' .... />

    -- saves 'k_last_insert_id' into 'populated_authors__array' variable:

      <cms:set related_author_id = k_last_insert_id />
      <cms:set populated_authors__array. = _input_author_hash scope='parent' />

      <cms:put "populated_authors__array.<cms:show _input_author_hash />" "[]" is_json='1' scope='parent' />
      <cms:put "populated_authors__array.<cms:show _input_author_hash />.page_id" related_author_id scope='parent' />
      <cms:put "populated_authors__array.<cms:show _input_author_hash />.name" _input_author scope='parent' />

</cms:if>
