Allowed Values list in drupal CCK Fields

I'm basically looking开发者_如何学编程 to simply print out each of the allowed values in a CCK field..

i know the allowed values are stored inside a text field within the table: 'content_node_field'.

the values are then stored within 'global_settings'

I'm looking to somehow print out each individual allowed value using a PHP loop.

however with all values being stored within one text field.. im finding it hard to print out each value individually.

Something like this should do the trick.

// Get the global_settings like you described.
$serialized_data = db_result(db_query("..."));
// Unserialize the data.
$unserialized_data = unserialize($serialized_data)
// Foreach the allowed values.
$values = array();
foreach(explode("\n", $unserialized_data['allowed_values']) as $value) {
  $values[] = $value;
}

If I am getting your question right, you can create PHP arrays by simply suffixing the [] to the names of the fields, so for example:

<input type="text" name="myname[]" />

Now you can get the values of the array like this:

foreach($myname as $value)
{
  echo $value . '<br />';
}

Update Based On Comment:

You can use the json_decode function to convert your data to array and then manipulate accordingly:

Example:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json, true));
