php json encode problem

Question

In order to access this data via ajax, how can I give each json encoded value a constant name?

 $data = array();
 foreach($query->result() as $row) {
 $data[$row->id] = $row->name;
 }

This returns json in this format:

{"12428":"Alpine 12\" Single-Voice-Coil 4-Ohm Subwoofer",}

The id (12428) is not constant and therefore, I have nothing constant to look for when trying to decode the data with ajax.

How can I change the php code to add a constant value foreach of the encoded json items?

Answer 1

$data = Array();
foreach($query->result() as $row) {
 $data[] = Array("id" => $row->id, "name" => $row->name);
}

Then, your JSON object looks like:

[{"id":"12428","name","Alpine 12\" Single-Voice-Coil 4-Ohm Subwoofer"}]

You can now loop through that array and get the id and name of each element.

Answer 2

Who cares.

js> d = {"12428":"Alpine 12\" Single-Voice-Coil 4-Ohm Subwoofer"}
[object Object]
js> for (i in d)
{
 print(d[i]);
}
Alpine 12" Single-Voice-Coil 4-Ohm Subwoofer

• Ignacio Vazquez-Abrams: Yes, hence the "js>". print() is specific to the REPL though.
