Drupal 7 .10 hook_menu implementation error - drupal

I am trying to figure out why hook_menu implementation is not working anymore after upgrade from 7.4 to 7.10 for a custom module Menu links were working properly until update to latest version. after update all custom module links are deleted from table menu_links and menu_router.
After many attempts, I also installed a fresh version for D7.10 and created a simple custom module with one item link only (see code below) for testing purpose only. The link is not implemented once the module is enabled. Tables menu_links and menu_routers are not updated.
I have been looking around many possible errors and solution without success.
Really stacked now. What makes me doubt is that I do not see anybody else having the same issue... Any suggestion? Thank you
function misite_menu() {
$items = array();
$items['a/main'] = array(
'title' => 'main',
'page callback' => 'main',
'description' => t('Main front page'),
'access callback' => TRUE,
);
return $items;
}
function misite_theme() {
return array(
'main' => array
(
'template' => 'main',
'variables' => array('title' => NULL),
),
);
}
function main() {
$path = drupal_get_path('module', 'a');
$title = t('');
$build['mainelement'] = array(
'#theme' => 'main',
'#title' => $title,
);
$output = drupal_render($build);
return $output;
}

From the looks of this line:
$path = drupal_get_path('module', 'a');
Your module is called a.
In Drupal, the convention for hook naming is MODULE_NAME_name_of_hook() (see http://api.drupal.org/api/drupal/includes--module.inc/group/hooks/7).
This is true for both hook_menu() and hook_theme() so in your case if the module is called a your functions should be names a_menu() and a_theme().
If you make changes to any hooks make sure you clear Drupal's cache so the relevant registrys are updated.

Drupal - using views_embed_view with an external Drupal site

I have two Drupal sites hosted on different servers. In the main they need to operate separately however site1 has one specific content type which I'd like to show in a list on site2.
I can't simply use feeds to import as the original has to remain and if edited, the changes be instantly reflected on both sites. Site2 has no requirement to edit the content - only show it.
The content is already being presented in a list on site1. The list was created using views.
My intention was to call the view on site2 using the following code in a custom module.
function site2_menu() {
$items = array();
$items['content-from-site1'] = array(
'title' => 'Content from Site1',
'page callback' => 'site_two_list',
'access arguments' => array('access content'),
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
function site2_list() {
db_set_active('site1');
$content = views_embed_view('articles', 'default');
db_set_active('default');
return $content;
}
site1 DB is defined in the settings.php file.
However this isn't returning any data. Using the same approach on Site1 (without switching DBs) works fine.
Was I being over-optimistic in hoping this approach would work or am I missing something obvious?
If this isn't likely to work, what would the alternative be? I can do my own SQL query, but I'd prefer to use views for built in arguments, pagination, templates, etc.
Thanks.
I've not been able to use views_embed_view, however I have been able to use views_get_view to retrieve everything I need and iterate over the results myself. It's a very close second.
function site2_menu() {
$items = array();
$items['content-from-site1'] = array(
'title' => 'Content from Site1',
'page callback' => 'theme_site2_list',
'access arguments' => array('access content'),
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
function site2_theme() {
return array (
'site2_list_page' => array(
'arguments' => array('content' => NULL),
'template' => 'templates/site2-list-page'
)
);
}
function theme_site2_list() {
db_set_active('site1');
$view = views_get_view('articles');
$view->base_database = "site1";
$view->init_display();
$view->pre_execute();
$view->execute();
db_set_active('default');
foreach ($view->result as $key => $data) {
$content[$key]['nid'] => $data->nid;
$content[$key]['title'] => $data->node_title;
$content[$key]['body'] => $data->field_body;
$content[$key]['image'] => $data->field_field_image;
}
return theme('site2_list_page', array('content' => $content));
}
Then in site2-list-page.tpl.php I can use the $content array to do what I need. It's not quite as clean as a simple views_embed_view, but it's a close second and allows the content from one site to be pulled to another fairly easily.

Only partial theming of custom form

I've constructed a custom module to create a form. Now I'm stuck on the theming. I already have a CSS stylesheet for the form, since my company is part of the government and they have a preset branding. So I wanted to change the HTML used by the default form theme functions of Drupal thus implementing the correct style.
But only the form-tag of the form gets rendered. The fieldset and elements are not rendered. When the theme functions are removed the default theming kicks in and the form renders normally (but of course without the requested theming).
What I have tried so far:
Added a hook_theme function to add theme functions
function publicatieaanvraagformulier_theme() {
return array(
'publicatieaanvraagformulier_form' => array(
'arguments' => array("element" => NULL)
),
'publicatieaanvraagformulier_fieldset' => array(
'arguments' => array("element" => NULL)
),
'publicatieaanvraagformulier_form_element' => array(
'arguments' => array(
"element" => NULL,
"value" => NULL
)
)
);
}
Added ['#theme'] to the form-element, fieldset-element and the form-elements
$form['#theme'] = "publicatieaanvraagformulier_form";
$form['groep'] = array(
'#title' => t("Please fill in your details"),
'#type' => "fieldset",
'#theme' => "publicatieaanvraagformulier_fieldset"
);
$form['groep']['organisatie'] = array(
'#title' => t("Organization"),
'#type' => "textfield",
'#attributes' => array("class" => "text"),
'#theme' => "publicatieaanvraagformulier_form_element"
);
Added the actual theme function based on the default ones in form.inc
function theme_publicatieaanvraagformulier_form($element) {
function theme_publicatieaanvraagformulier_fieldset($element)
function theme_publicatieaanvraagformulier_form_element($element, $value)
I haven't included the code of these functions because even with the default themefunctions code, they don't work. Therefor I assume they are not the source of the problem.
The form is called
//Get the form
$form = drupal_get_form('publicatieaanvraagformulier');
//Add messages
$errors = form_get_errors();
if (!empty($errors)) {
$output .= theme("status_messages","error");
}
//Show form
$output .= $form;
return $output;
I haven't found similar 'complicated' examples of theming a form, but have pieced together the former from books and online searches.
Hopefully someone has an answer to this problem (point out the mistake I made).
Greetings

Drupal 7 example module, page not found, why?

I wrote a simple test module example, 2 files, test.module, test.info, and enabled them in drupal 7 modules.
I cleared all the cache, and still when i'm trying to go to localhost/drupal/hello , i get drupal 404 page not found, why is that?
Here is my code:
<?php
function test_world_help($section) {
switch ($section) {
case 'admin/help#hello_world':
$output = '<p>Hello world help...</p>';
return $output;
case 'admin/modules#description':
return 'Hello world module description...';
}
}
function test_world_menu($may_cache) {
$items = array();
if ($may_cache) {
}
else {
$items['hello'] = array(
'title' => 'Hello world page...',
'callback' => 'test_world_page',
'access' => TRUE,
'type' => MENU_CALLBACK
);
}
return $items;
}
function test_world_page() {
return '<p>Hello world!</p>';
}
You have posted almost the same question once and twice before. Why don't you update the original one instead of posting new ones?
The hook_menu() does not have the $may_cache argument in Drupal 7. You should remove it. However, it should not solve your problem as it is unset and false. Thus, the $items should still be populated.
It is correct, as jprofitt says, that you should change 'callback' to 'page callback'.
There is no such thing as 'access', but there is 'access callback' and 'access arguments'. You are most likely looking for 'access callback'. However, you can't just set it to 'true'. It expects a function name which returns either 'true' or 'false'. It defaults to 'user_access', so you should just leave it that way. However, you might want to set 'access arguments' to something like 'access content'.
Does the following piece of code work better?
function test_world_menu() {
$items = array();
$items['hello'] = array(
'title' => 'Hello World!',
'page callback' => 'test_world_page',
'access arguments' => array('access content'),
'type' => MENU_CALLBACK
);
return $items;
}
It seems that you haven't really had a look at the documentation. I might be wrong. However, the documentation at api.drupal.org is always a good start to look when you want to learn the basics of how something work.
You should probably change 'callback' to 'page callback', as I don't believe hook_menu() has just a plain "callback" option. And since you're working with Drupal 7, its hook_menu() actually doesn't have parameters.
Uninstall and reinstall your custom module. I hope this will help you. Because it's necessary for drupal core to know the newly created path created using hook_menu.

hook_load/hook_view not called

I have a module with four node types declared. My problem is, hook_load, hook_view is never called. I used drupal_set_message to find out if certain hook is being called. And I found out hook_load, hook_view isn't. Just to give you clear picture, here's my structure of hook_load
HERE'S UPDATED ONE
function mymodule_node_info(){
return array(
'nodetype1' => array(
'name' => t('nodetype1'),
'module' => 'mymodule_nodetype1',
'description' => t('....'),
'has_title' => TRUE,
'title_label' => t('Title'),
'has_body' => TRUE,
'body_label' => t('Body'),
),
'nodetype2' => array(
......
'module' => 'mymodule_nodetype2',
......
),
'nodetype3' => array(
......
'module' => 'mymodule_nodetype3',
......
),
'nodetype4' => array(
......
'module' => 'mymodule_nodetype4',
.......
),
);
}
function mymodule_nodetype1_load($node){
$result = db_query('SELECT * from {nodetype1table} WHERE vid = %d'
$node->vid
);
drupal_set_message("hook_load is provoked.","status");
return db_fetch_object($result);
}
I don't know why it is not called. I wrote this code base on drupal module writing book and follow the instructions. I've tried sample code from that book and it works ok. Only my code isn't working. Probably because of multiple node types in one module. Any help would be highly appreciated.
Your code doesn't work because hook_load() and hook_view() aren't module hooks: they're node hooks. The invocation is based off of content type names, not module names.
So, first you need to have declared your content types using hook_node_info():
function mymodule_node_info() {
$items = array();
$items['nodetype1'] = array(
'name' => t('Node Type 2'),
'module' => 'mymodule_nodetype1',
'description' => t("Nodetype 1 description"),
);
$items['nodetype2'] = array(
'name' => t('Node Type 2'),
'module' => 'mymodule_nodetype2',
'description' => t("Nodetype 2 description"),
);
$items['nodetype3'] = array(
'name' => t('Node Type 2'),
'module' => 'mymodule_nodetype3',
'description' => t("Nodetype 3 description"),
);
return $items;
}
Then, you need to use the name of the module you specified for each content type declared in hook_node_info() for your node hooks. That is, mymodule_nodetype1_load(), mymodule_nodetype2_view(), etc.
Edit
If you're trying to have a non-node based module fire when a node is viewed or loaded, you need to use hook_nodeapi():
function mymodule_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
switch ($op) {
case 'view':
mymodule_view_function($node);
break;
case 'load':
mymodule_load_function($node);
break;
}
}
Replace mymodule_load_function() and mymodule_load_function() with your own custom functions that are designed to act on the $node object.
Edit 2
Besides the syntax error in your hook_load() implementations, there's a piece of your code outside of what you're providing that's preventing the correct invocation. The following code works (if you create a nodetype1 node, the message "mymodule_nodetype1_load invoked" appears on the node): perhaps you can compare your entire code to see what you're missing.
function mymodule_node_info() {
return array(
'mymodule_nodetype1' => array(
'name' => t('nodetype1'),
'module' => 'mymodule_nodetype1',
'description' => t('....'),
'has_title' => TRUE,
'title_label' => t('Title'),
'has_body' => TRUE,
'body_label' => t('Body'),
),
'mymodule_nodetype2' => array(
'name' => t('nodetype2'),
'module' => 'mymodule_nodetype2',
'description' => t('....'),
'has_title' => TRUE,
'title_label' => t('Title'),
'has_body' => TRUE,
'body_label' => t('Body'),
),
);
}
function mymodule_nodetype1_form(&$node, $form_state) {
// nodetype1 form elements go here
return $form;
}
function mymodule_nodetype2_form(&$node, $form_state) {
// nodetype2 form elements go here
return $form;
}
function mymodule_nodetype1_load($node) {
$additions = new stdClass();
drupal_set_message('mymodule_nodetype1_load invoked');
return $additions;
}
function mymodule_nodetype2_load($node) {
$additions = new stdClass();
drupal_set_message('mymodule_nodetype2_load invoked');
return $additions;
}
If you're not reseting your environment after changes to your module, you might be running into caching issues. You should test your code in a sandbox environment that can be reset to a clean Drupal installation to ensure you're not focusing on old cruft from previous, incorrect node implementations.
Additionally, you should only be using hook_nodeapi() if you are trying to act on content types that are not defined by your module. Your content types should be using the node hooks (hook_load(), hook_view(), etc.).
Finally, it may be the case that you're using the wrong hooks because you're expecting them to fire in places they are not designed to. If you've gone through everything above, please update your post with the functionality you're expecting to achieve and where you expect the hook to fire.
I found the culprit why your code doesn't work. It's because I was using the test data created by the old codes. In my old codes, because of node declaration inside hook_node_info uses the same module value, I could only create one hook_form implementation and use "switch" statement to return appropriate form. Just to give you clear picture of my old codes-
function mymodule_node_info(){
return array(
'nodetype1' => array(
.....
'module' => 'mymodule',
.....
),
'nodetype2' => array(
......
'module' => 'mymodule',
......
),
.......
);
}
function mymodule_form(&$node, $form_state){
switch($node->type){
case 'nodetype1':
return nodetype1_form();
break;
case 'nodetype2':
return nodetype2_form();
break;
.....
}
}
When I created new data after I made those changes you have provided, hook_load is called. It works! I've tested several times(testing with old data created by previous code and testing with new data created after those changes) to make sure if that's the root cause and, I got the same result.I think drupal store form_id or module entry value of node declaration along with data and determine the hook_load call. That's probably the reason why it doesn't think it's a data of this node and thus hook_load isn't invoked.
And Thank you so much for your help.

Drupal user_hook in custom module

Modifying download_count module to include information about users who downloaded files. Want to show this info on users' profile pages.
Here's the code:
function download_count_user($op, &$edit, &$account, $caterory = NULL) {
if ($op == 'view')
{
$result = db_query("SELECT filename FROM file_downloads_users WHERE user_id = %d", $account->uid);
while ($file_array = db_fetch_object($result)) {
$file_str .= $file->filename . '<br/>';
}
$items['downloads'] = array(
'title' => t('Files'),
'value' => $file_str,
'class' => 'member'
);
return array(t('Downloads')=>$items);
}
}
Doesn't give me any errors but doesn't show anything on My Account page either.
You don't want to modify a module. Drupal is built very very carefully to avoid having to hack core or contrib. Unless of course you are contributing a patch back.
The right way is to build your own custom module to do this (that would require the user downloads module) and implement the hook almost exactly what you're doing here.
The function is getting run (module enabled, var_dump ing or krumo'ing causes output?, cache cleared)
The way you are keying your variables is for Drupal 5.x and below. In D6, you add to $account->content. Which version of drupal are you using?
Check out user_user() (in user.module):
$account->content['user_picture'] = array(
'#value' => theme('user_picture', $account),
'#weight' => -10,
);
$account->content['summary']['file_downloads'] = array(
'#type' => 'user_profile_item',
'#title' => t('File Downloads'),
'#value' => $file_str,
'#weight' => 1
);
