function node_get_types

4.7 node.module node_get_types()
5 node.module node_get_types($op = 'types', $node = NULL, $reset = FALSE)
6 node.module node_get_types($op = 'types', $node = NULL, $reset = FALSE)

Builds a list of available node types, and returns all or part of this list.

Parameters

$op: The format in which to return the list: 'type', 'types', 'module', 'name', or 'names'. See return value section below for details.

$node: A node object, an array representation of a node object, or a node type name string. See return value section below for details.

$reset: Whether or not to reset this function's internal cache (defaults to FALSE).

Return value

If $node is supplied and it doesn't correspond to a known node type, or if $op is 'type', 'name', or 'module' and $node is not given, the function returns FALSE. Otherwise, the return value depends on the value of $op:

  • 'types': An array of all available node type objects, keyed by machine name.
  • 'type': The single node type object indicated by $node.
  • 'names': An array of the display names of all available node types, keyed by machine name and sorted by display name.
  • 'name': The single node type display name indicated by $node.
  • 'module': The name of the node type module indicated by $node.

The core that allows content to be submitted to the site. Modules and scripts may programmatically submit nodes using the usual form API pattern.

Code

function node_get_types($op = 'types', $node = NULL, $reset = FALSE) {
  static $_node_types, $_node_names;

  if ($reset || !isset($_node_types)) {
    list($_node_types, $_node_names) = _node_types_build();
  }

  if ($node) {
    if (is_array($node)) {

    }
    elseif (is_object($node)) {
      $type = $node->type;
    }
    elseif (is_string($node)) {
      $type = $node;
    }
    if (!isset($_node_types[$type])) {
      return FALSE;
    }
  }
  switch ($op) {
    case 'types':
      return $_node_types;
    case 'type':
      return isset($_node_types[$type]) ? $_node_types[$type] : FALSE;
    case 'module':
      return isset($_node_types[$type]->module) ? $_node_types[$type]->module : FALSE;
    case 'names':
      return $_node_names;
    case 'name':
      return isset($_node_names[$type]) ? $_node_names[$type] : FALSE;
  }
}

Just a quick reference to what the different options output.

<?php
// call
print_r(node_get_types() );
print_r(node_get_types('types') );
// output
array(
'node_type' => array(
    'name' => 'Human Readable name',
    'module' => 'node',
     ...
  )
);
// call
print_r(node_get_types('names'));
// output
array(
  'node_type' => 'Human readable name', // name not sanitized!
);
// call
print_r(node_get_types('name', 'node_type') );
// output
"Human readable name"
// call
print_r(node_get_types('module', 'node_type') );
// output
node (or whatever module is).
?>

Finally, to get an simple array of node types

<?php
array_keys(node_get_types());
array_keys(node_get_types('types'));
array_keys(node_get_types('names'));
?>

To get a /sanitized/ array of node types names suitable for fapi checkboxes/select

<?php
array_map('check_plain', node_get_types('names'));
?>

Hefox's example output indicates that an array of arrays is returned by this function, but it actually returns an array of objects.

// Output
array(
  'story' => stdClass(
    name
    module
    ...
  )
);

Suppose you have a $node object and you want to get the human-readable name for this node type, you would use:

<?php
  $node = node_load(1);
  $types = node_get_types();
  $human_readable = $types[$node->type]->name;
?>

I want to retreive all nodes of type forum. Then what will be the code?

Posted by Maedi on

Be interested to see if this can be done with a drupal function, however your best bet is to create a View then use views_get_view_result('view_name') to return a PHP array of objects, each one representing a row and its fields in your view.

In Drupal 7, you'll need to use :

<?php
$types = _node_types_build()->types;
?>

Thanks

Use node_type_get_types() instead.

Posted by Ayesh on

Note that this function returns node objects. if you want a simple list of node types as an array, use node_type_get_names() instead.
