The doc for hook_nodeapi() is pretty clear that the 3rd and 4th params must be options. However, some core implemtations make it required.


This cause's errors when invoking hook_nodeapi with just the 1st 2 params (which are all that should be required).

Title: Severla core implementations of hook_nodeapi() have required 3rd parameters » Several core implementations of hook_nodeapi() have required 3rd parameters
Issue tags: +Novice

tagging as Novice, since this is a really easy patch.

All core implenetations need to be checked, but upload_nodeapi(), trigger_nodeapi() and path_nodeapi() clearly have the problem.

Basically I fixed all implementations of hook_nodeapi in core (more than 3 !). (My first core patch)

I think this needs work - some of the changes add a 4th param (not needed) or change the name of the 3rd param:

-function comment_nodeapi(&$node, $op, $arg = 0) {
+function comment_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {

I think we don't need the change above at all. The main thing is to make sure that any 3rd or 4th params defined are optional (have a default value).

For example, I would change path_nodeapi() to:

function path_nodeapi(&$node, $op, $arg = NULL) {

What about statistics module ? third parameter is 0, not NULL. Same for taxonomy.
function statistics_nodeapi(&$node, $op, $arg = 0) {

I think it's fine for them to be 0 instead of NULL at this point - as long as there is a default value, it's optional.

ok, so the modified modules are:


Applied this patch, enabled all those module and did some basic functional tests. Didn't see (or expect) any errors.

Patch also looks good - minimal change to comply with the API and make 3rd and 4th params optional.

So basically, i wrote my first patch for core :) /me is happy :)
I'll continue with core issues tagged "Novice", they fit me well.

Im also seeing this issue, im curious if I should apply the patch here..

Warning: Missing argument 4 for views_attach_nodeapi(), called in /var/www/html/content/sites/all/modules/apachesolr/ on line 63 and defined in views_attach_nodeapi() (line 86 of /var/www/html/content/sites/all/modules/views_attach/views_attach.module).

@gateway69 - no, it looks to be a corresponding bug in the views_attach module. Please file the bug there.
