Set permission for creating nodes in code - drupal

Question

Can I set permissions to allow authenticated users to add nodes of a custom type? I need to do that in module i'm trying to create. As I can see hook_permission it's actually just for creating new permissions.

Answer 1

If your module name is say mymodule, then defien a your "create node" permission in hook_permission. Then implement hook_node_access to check and return permission for the content type you have implemented.
SAMPLE CODE.
NB: It won't work out of the box, you got to replace your module name, permission name and the content type name to get it to work. And don't forget to clear your cache, TWICE!.
/**
* Implements hook_permission().
*
*/
function mymodule_permission() {
// define your add permission.
// Naming of "array key" is important. We use that later.
return array(
'YOUR CONTENT NAME: add' => array(
'title' => t('Add Project Management Team'),
),
);
}
/**
* Implements hook_node_access().
*/
function mymodule_node_access($node, $op, $account = NULL) {
$type = is_string($node) ? $node : $node->type;
// make sure you are responding to content type defined by your module only.
if ($type == 'YOUR_CONTENT_TYPE_NAME_HERE') {
// If no account is specified, assume that the check is against the current logged in user
if (is_null($account)) {
global $user;
$account = $user;
}
if ($op == 'create' AND user_access('YOUR CONTENT NAME: add', $account)) {
return NODE_ACCESS_ALLOW;
}
}
return NODE_ACCESS_IGNORE;
}
