i am a newby to drupal.
here is my problem:
on my main page.tpl.php i have this code lines:
"if ( $is_front == TRUE ) {
print views_embed_view('all_product_by_type_thin', "default", "canon");
print views_embed_view('all_product_by_type_thin', "default", "Nikon");
}"
as you can see, in case of the front page i print the "all_product_by_type_thin" view while sending parameter "cannon" and "nikon"
the result of the all_product_by_type_thin view is altered inside the views-view-unformatted--all_product_by_type_thin.tpl.php file.
in that file i am wrapping the view results in all kind of divs.
what i need to do though, and cant figure out a way to do it, is get the argument i sent the view "canon" or "nikon" inside the php code of views-view-unformatted--all_product_by_type_thin.tpl.php
any idea ?
Inside your Views theme file ie. views-view-unformatted--all_product_by_type_thin.tpl.php you should have access to the $view object.
One of the attributes of this object will contain the arguments passed to the view. You can do a print_r and find this attribute and hence, the arguments.

I have a preprocess function:
[MYTHEMENAME]_theme_preprocess_views_view_fields__random_quote__block(&$vars)
and then a template file to render the variables:
views-view--random_quote--block.tpl.php
I can easily set a variable like so:
$vars['bam'] = 'whatever';
and display that in my template file. Now my question is, how do I pass the contents of a field to my template? Something like:
$vars['customer_name'] = 'field_customer_name';
Where 'field_customer_name' is a field in the content type. I have tried using the field api and I am getting nowhere. My view is getting that field and I can see the data in the preview of the view content
I still haven't figure out how to do this, but I ended up using a fields tpl (in this case: views-view-fields--random_quote.tpl.php) so I could format each field like so
<cite><b><?php print strip_tags($fields['field_customer_name']->content); ?></b>
Ok, I figured out how to do it!
$entity = $vars['view']->result[0]->_field_data['nid']['entity'];
$vars['customer_name'] = '$entity->field_customer_name[$entity->language][0]['value'];
Hope this helps someone
I'm building a module that manages ad units in the form of blocks that all need to be aware of each other and pass information around.
Thus I need to find a simple hook or other function to get a listing of every block that will be used on the page, so I can be sure to know the entire list of ad units on the page.
I've tried hook_block_list_alter() but this seems to return the ENTIRE list of blocks that exist in my Drupal install, with no designation of which blocks are actually going to be rendered or not on this page.
So, now what do I do?
I think it's got something to do with the order hook_block_list_alter() is called in but I'm not entirely sure. Either way the following code will get you a list of all blocks in the current page context. Be sure not to put this in a hook_block_list_alter() function or you'll get an exception caused by infinite nesting.
global $theme;
$all_regions = system_region_list($theme);
$blocks = array();
foreach (array_keys($all_regions) as $region) {
$blocks += block_list($region);
}
If you only need the blocks in a particular region you can ditch most of the code above and just go with:
$blocks = block_list('region_name');
I ran into the same problem when calling block_list('content'). Looking at the code for this function I found it calls two other functions, _block_load_blocks() and _block_render_blocks(). The problem seems to occur in _block_render_blocks() as the display text is not added to the content object. This is different from the other block objects that pass through the function.
To get around this, instead of calling block_list(), I called _block_load_blocks() directly. This returns an array of blocks grouped by region, bypassing the _block_render_blocks() call.
Now we can check for blocks in the content region without the content text disappearing. Huzzar!
I had a similar requirement when implementing an adserver (DFP). My solution was to define an array as a global variable, and include php code in each ad unit block that added a new element to the array.
Then, once all blocks on the page have been executed, you can simply access the global variable to see which ad blocks were called. Because the code to build the list of blocks being called is part of each block, it doesn't matter whether the blocks are displayed in a region, in a panel, or anywhere else.
In my case, I wanted to use the information to add scripts to the <head> section that reference only the add units from the blocks being placed. My complete solution was as follows:
1) Implement hook init to create a global variable in which to store information about which blocks are being displayed (you need to create a custom module to contain this code):
YOURMODULE_custom_init() {
$GLOBALS['dfp-ads'] = array();
}
2) Enable the core php module
3) Add php code at the end of each ad block to add a row to the array created in step 1
<?php
$GLOBALS['dfp-ads']['AD_OR_BLOCK_NAME_GOES_HERE']="AD SPECIFIC SCRIPT GOES HERE";
?>
4) Implement THEME_preprocess_html in my template.php file to access the global variable, build the script, and add the script to <head> section with a call to drupal_add_html_head
function YOURTHEME_preprocess_html(&$vars) {
$inline_script = LOGIC TO ACCESS $GLOBALS['dfp-ads'] AND BUILD SCRIPT GOES HERE;
$element = array(
'#type' => 'markup',
'#markup' => $inline_script,
);
drupal_add_html_head($element, 'google-dfp');
}
It sounds from your description that you don't need the list of ad blocks to build javascript for the head section, but instead want to use the information to modify the contents of the blocks themselves.
In that case insteaad of THEME_preprocess_html, you could try hook_page_alter(&page)
The api page for that hook states that individual "Blocks may be referenced by their module/delta pair within a region:"
// The login block in the first sidebar region.
$page['sidebar_first']['user_login']['#block'];
Hope that helps someone!
I'm having trouble dealing with hooks for the Views module in Drupal. What I'm trying to do is determine which view is being rendered so that I can identify it and make changes to it. IOW, I don't know ahead of time which view I'm working on.
In the code below, I've replaced my actual module name with "MODULENAME".
In my .module file I have included a file MODULENAME.views.inc file with the following:
include_once ( dirname(__FILE__) . '/MODULENAME.views.inc');
In the .views.inc file, I have a MODULENAME_views_api function like this:
function MODULENAME_views_api() {
return array('api' => 2, 'path'=> drupal_get_path('module', 'MODULENAME'),
);
}
Those seem to work just fine. So, now I try to get down to business with an actual hook...
function MODULENAME_views_pre_render(&$view) {
$get_view_info = $view->name;
echo $get_view_info;
}
MODULENAME_views_pre_render();
The problem is this throws an error, "Missing argument 1 for MODULENAME_views_pre_render().
So, obviously it expects me to pass in an identifier of some sort to tell it which view I want. But that's the whole point of this function is to determine which view is being rendered. If I knew the answer to that, then I wouldn't need to call the function in the first place.
Am I missing something obvious? Is there a function call that I can use to return this identifier?
You hook into things by implementing hooks, so this part of your code is ok:
<?php
function MODULENAME_views_pre_render(&$view) {
$get_view_info = $view->name;
echo $get_view_info;
}
But this:
<?php
MODULENAME_views_pre_render();
Why? You're not generating a view, Views is. It's not your job to invoke the hook. You just implement it.
So, you need to make changes to the view? you do it right there:
<?php
function MODULENAME_views_pre_render(&$view) {
if ($view->name == 'TheViewIWantToModify') {
// Make some changes to the $view
}
}
And that's it.
Also, note that depending on the type of modifications you want to do, you might want to implement another hook instead of hook_views_pre_render(). Take a look at the docs/docs.php file that comes with Views (version 6.x-2.12 at least, I don't know which version you have, and BTW you should indicate this) and starting on like 538 you'll see a few hook_views_pre_ and hook_views_post_ type of hooks (that is, their descriptions, for you to know what each of them are good for), and then you can decide which one to implement in your module.
I have a Drupal site and I have setup a view to power the front page.
My goal is to be able to pass 0-2 arguments to the home page, that get passed into the view. However, I still need the normal Drupal pages to work. The list of arguments is known.
For example:
mysite.com/berlin/birds would pass in "berlin" as the first argument and "birds" as the second argument to the view that powers the front page.
mysite.com/berlin would just pass in one argument, "berlin"
mysite.com/admin would load the normal admin pages in Drupal
I'm not clear on how to achieve this. Is there a hook I can use? I can't find one or think of one. Is there a way to specify this in the argument for the view itself? Perhaps I can write a hook that interjects when the URL is being loaded, and rewrite in the background?
The solution I currently have is to add these paths (since my arguments are known) to the menu system. This works, except that when I the pages they aren't the front page, so the pages don't use the node themes I want (they use the node details theme).
I don't think you can really do this without custom code. The View needs a path before it starts taking arguments, and your URLs start with the arguments. What you can do is fake it with custom code. I've used something like this:
/**
* Implements hook_init().
*/
function mymodule_custom_init() {
$item = menu_get_item(); // Matching Drupal path
if (!$item) { // There is no matching Drupal path.
$_GET['q'] = 'view_path/' . $_GET['q']; // Fake path path.
} // if
} // mymodule_custom_init
Then you give the view a path of "view_path" and it responds to everything that doesn't match anything else in Drupal's paths.
There is a spot in the views UI for "Argument handling code" that takes a small snippet of php - http://drupal.org/node/70145
You could run some code there that checks to see if you are on the front page (or arguments are not present or whatever)and insert the arguments you want.
Another way is to set arguments via a hook_views_pre_view or hook_views_pre_build. Is better because you are sure you don't break other stuff (like another view block).
function MYMODULE_views_pre_view(&$view){
if ($view->name == 'your_view_name' && drupal_is_front_page()) {
$view->set_arguments(array('you_argument','you_second_argument'));
}
}
How can I build a block in Drupal which is able to show the node ID of the view page the block is currently sitting on?
I'm using views to build a large chunk of my site, but I need to be able to make "intelligent" blocks in PHP mode which will have dynamic content depending on what the view is displaying.
How can I find the $nid which a view is currently displaying?
Here is a more-robust way of getting the node ID:
<?php
// Check that the current URL is for a specific node:
if(arg(0) == 'node' && is_numeric(arg(1))) {
return arg(1); // Return the NID
}
else { // Whatever it is we're looking at, it's not a node
return NULL; // Return an invalid NID
}
?>
This method works even if you have a custom path for your node with the path and/or pathauto modules.
Just for reference, if you don't turn on the path module, the default URLs that Drupal generates are called "system paths" in the documentation. If you do turn on the path module, you are able to set custom paths which are called "aliases" in the documentation.
Since I always have the path module turned on, one thing that confused me at first was whether it was ever possible for the arg function to return part of an alias rather than part of system path.
As it turns out, the arg function will always return a system path because the arg function is based on $_GET['q']... After a bit of research it seems that $_GET['q'] will always return a system path.
If you want to get the path from the actual page request, you need to use $_REQUEST['q']. If the path module is enabled, $_REQUEST['q'] may return either an alias or a system path.
For a solution, especially one that involves a view argument in the midst of a path like department/%/list, see the blog post Node ID as View Argument from SEO-friendly URL Path.
In the end this snippet did the job - it just stripped the clean URL and reported back the very last argument.
<?php
$refer= $_SERVER ['REQUEST_URI'];
$nid = explode("/", $refer);
$nid = $nid[3];
?>
Given the comment reply, the above was probably reduced to this, using the Drupal arg() function to get a part of the request path:
<?php
$nid = arg(3);
?>
You should considder the panels module. It is a very big module and requires some work before you really can tap into it's potential. So take that into considderation.
You can use it to setup a page containing several views/blocks that can be placed in different regions. It uses a concept called context which can be anything related to what you are viewing. You can use that context to determine which node is being viewed and not only change blocks but also layout. It is also a bit more clean since you can move the PHP code away from admin interface.
On a side note, it's also written by the views author.
There are a couple of ways to go about this:
You can make your blocks with Views and pass the nid in through an argument.
You can manually pass in the nid by accessing the $view object using the code below. It's an array at $view->result. Each row in the view is an object in that array, and the nid is in that object for each one. So you could run a foreach on that and get all of the nid of all rows in the view pretty easily.
The first option is a lot easier, so if that suits your needs I would go with that.
New about Drupal 7: The correct way to get the node id is using the function menu_get_object();
Example:
$node = menu_get_object();
$contentType = node_type_get_name($node);
Drupal 8 has another method. Check this out:
arg() is deprecated
