Codeigniter和Datamapper：从ID列中检索所有ID，并将其附加到数组

Question

I am having trouble collecting all the ids from the ID column. What the code above does is getting only one ID, at least it goes to the array but I want to take all of them.

$getArticlesId = new Article_model();
$getArticlesId->select('id');
$getArticlesId->get();
$anarray = $getArticlesId->to_array(array('id'));

That returns: SELECT articles . id FROM ( articles )

and Array ( [id] => 43 ) , but there must be 10 more

What I am doing wrong ?

Answer 1

to_array() generates an array with your specified field(s). all_to_array() generates multiple arrays with your specified id field. $anarray[0]['id'] should be your first id. Hope this is what you're looking for.

Answer 2

This should work:

// RETURN ORM OBJECT
    $getArticlesId = new Article_model();
    $getArticlesId->select('id');
    $getArticlesId->get_iterated();
    $getArticlesId_Total = $getArticlesId->result_count();
// -------- EOF - RETURN ORM OBJECT


// GENERATE PHP ARRAY FROM OBJECT
if ($getArticlesId_Total > 1) 
{
    $anarray = $getArticlesId->all_to_array();
}
// -------- EOF - GENERATE PHP ARRAY FROM OBJECT

You may also want to try all_to_single_array() . http://datamapper.wanwizard.eu/pages/extensions/array.html
