Question

Ive got a problem. In each document I ve got fields: threads.id and posts.id.

I want to get the field name value for them so i can get data from the database.

Between the lines beneath i have marked the lines where i want to get the fields.

But it returns error because they are $doc is object.

How can i get the fields? I have to do it when it iterates the document and not when it iterates the $field and $value.

 // iterate document
 foreach ($results->response->docs as $doc)
 {

---------------------------------------
$forum_model->get_country_id_by_thread_id($doc[ threads.id ]);
$forum_model->get_user_id_by_thread_id($doc[ posts.id ]);
----------------------------------------

// iterate document fields / values
foreach ($doc as $field => $value)
{
    echo htmlspecialchars($field, ENT_NOQUOTES,  utf-8 ) . "<br />";
    echo htmlspecialchars($value, ENT_NOQUOTES,  utf-8 ) . "<br />";
    //echo $doc[ threads.title ] . "<br/>";
}

}

Answer 1

According to the PHPDocs I think you want...

$threads = $doc->getField( threads.id )

Answer 2

In most cases you can use:

$value = $doc->fieldname;

Alternatively, if your fieldname isn t a legal PHP variable,

$field = $doc->getField( field.name );
$value = $field[ value ];
