Drupal 7 Module Development

Recommendations

Info

Chapter 9 In the preceding case, the user dutiwrecl has been granted editing permissions by the node module. Other users may view the content because a node access module (in this case Domain Access, http://drupal.org/project/domain) has granted access. If you review our discussion of how the node_access() function operates, you can quickly see how handy this developer's utility can be. Summary This has been a long chapter, and we hope you found it rewarding. Understanding and using node access is one of the most powerful tools in the <strong>Drupal</strong> API. We have covered a wide array of topics, but the key points to remember are: • How access to a node is determined • To always use dynamic query syntax for node lists and to tag node queries with add_tag('node_access') • The differences between hook_node_access() and writing a node access module • How to alter Create, View, Update and Delete access to individual nodes • The three major operations controlled by the Node Access API • How to filter listing queries using the Node Access API [ 285 ]
Node Access • How to write your own node access module • How to modify existing node access modules • The importance of storing the data required by your rule set and loading it with hook_node_load() With an understanding of these elements and the debugging tools provided by Devel Node Access, you should be able to implement the access rules required for any <strong>Drupal</strong> project.
