Drupal - Create a menu programmatically in Drupal 7
If you are trying to do this in an update script, this should work:
$menus = array(
array(
'menu_name' => 'menu_test_one',
'title' => 'My Menu One',
'description' => 'Lorem Ipsum',
),
array(
'menu_name' => 'menu_test_two',
'title' => 'My Menu Two',
'description' => 'Lorem Ipsum',
),
array(
'menu_name' => 'menu_test_three',
'title' => 'My Menu Three',
'description' => 'Lorem Ipsum',
),
);
$links = array(
array(
array(
'link_title' => 'Link1',
'link_path' => 'http://yourdomain.com/link1',
'menu_name' => 'menu_test_one',
'weight' => 0,
'expanded' => 0,
),
array(
'link_title' => 'Link2',
'link_path' => 'http://yourdomain.com/link2',
'menu_name' => 'menu_test_one',
'weight' => 1,
'expanded' => 0,
),
),
array(
array(
'link_title' => 'Link3',
'link_path' => 'http://yourdomain.com/link3',
'menu_name' => 'menu_test_two',
'weight' => 0,
'expanded' => 0,
),
array(
'link_title' => 'Link4',
'link_path' => 'http://yourdomain.com/link4',
'menu_name' => 'menu_test_two',
'weight' => 1,
'expanded' => 0,
),
),
array(
array(
'link_title' => 'Link5',
'link_path' => 'http://yourdomain.com/link5',
'menu_name' => 'menu_test_three',
'weight' => 0,
'expanded' => 0,
),
array(
'link_title' => 'Link6',
'link_path' => 'http://yourdomain.com/link6',
'menu_name' => 'menu_test_three',
'weight' => 1,
'expanded' => 0,
),
),
);
// Save menu group into menu_custom table
foreach ($menus as $menu) {
// Look the table first if the data does exist
$exists = db_query("SELECT title FROM {menu_custom} WHERE menu_name=:menu_name", array(':menu_name' => $menu['menu_name']))->fetchField();
// Save the record if the data does not exist
if (!$exists) {
menu_save($menu);
}
}
$item = '';
foreach ($links as $layer1) {
foreach ($layer1 as $link) {
// Build an array of menu link
$item = array(
'link_path' => $link['link_path'],
'link_title' => $link['link_title'],
'menu_name' => $link['menu_name'],
'weight' => $link['weight'],
'expanded' => $link['expanded'],
);
// Look the table first if the data does exist
$exists = db_query("SELECT mlid from {menu_links} WHERE link_title=:link_title AND link_path=:link_path", array(':link_title' => $link['link_title'], ':link_path' => $link['link_path']))->fetchField();
// Save the record if the data does not exist
if (!$exists) {
menu_link_save($item);
}
}
}
Comments are welcome if my approach is wrong. Thanks.
Here's a way to easily populate a menu from an array :
<?php
function populate_menu($links, $menu_name, $plid = 0) {
foreach ($links as $link) {
$ls = array(
'menu_name' => $menu_name,
'link_title' => $link['link_title'],
'link_path' => $link['link_path'],
'plid' => $plid,
);
$newpid = menu_link_save($ls);
if (!empty($link['childs'])) {
populate_menu($link['childs'], $menu_name, $newpid);
}
}
}
$items = array(
array(
'link_title' => 'Menu1',
'link_path' => '<front>',
'childs' => array(
array(
'link_title' => 'Sub Item 1',
'link_path' => '<front>',
'childs' => array(
array(
'link_title' => 'Link item 1',
'link_path' => '<front>',
),
array(
'link_title' => 'Link item 2',
'link_path' => '<front>',
),
),
),
array(
'link_title' => 'Sub Item 2',
'link_path' => '<front>',
'childs' => array(
array(
'link_title' => 'Link item',
'link_path' => '<front>',
),
),
),
),
),
);
populate_menu($items, 'main-menu');
hook_menu()
is all you need to implement in you custom module. For creation of custom module, refer to this documentation.
//Define the menus in the function which goes in your MYMODULE.module file
function MYMODULE_menu() {
//the menu which will point to http://yoursite/first-menu
$items['first-menu'] = array(
'title' => 'First menu', // will appear as the name of the link
// Page callback, etc. need to be added here.
);
//the menu which will point to http://yoursite/second-menu
$items['second-menu'] = array(
'title' => 'Second menu', // will appear as the name of the link
// Page callback, etc. need to be added here.
);
//the menu which will point to http://yoursite/third-menu
$items['third-menu'] = array(
'title' => 'third menu', // will appear as the name of the link
// Page callback, etc. need to be added here.
);
return $items;
}
You could print the menu in any region by adding the following code to the page.tpl.php
file of you theme.
//add this line in <div id="header"></div> to print it in header.
<?php
$menu1 = menu_navigation_links('first-menu');
print theme('links__first_menu', array('links' => $menu1));
//print second menu just below first menu
$menu2 = menu_navigation_links('second-menu');
print theme('links__second_menu', array('links' => $menu1));
?>
You don't need to print third-menu
because by default it will appear at the navigation menu.
NOTE: This is not best practice at all for creating a navigation menu and adding it to a page. hook_menu() is for creating page callbacks and not for creating navigation menus. Please read THIS, which explains the differences. I answered this when I had started to learn Drupal and I don't recommend this answer anymore.
