I currently have a view (Drupal 6 using Views2) that properly aggregates a custom content type (videos) and filters them for a page display. When I create a block display, it previews the results in live preview just great, but when i go to the page expecting to see the block it doesn't appear.
I'm fairly certain the argument I'm attempting to pass it fails because when I select "Display all results" for "Action to take if argument does not validate:" the block shows up on the page just fine.
Any advice definitely appreciated.
you can use PHP code in the 'provide default argument' section. assuming you're using a menu callback to apply the argument you can do this:
<?php
if(args(0) == 'your-menu-path' && args(1) != ''){
return args(1)
}
?>
make sure you pass a default argument to 'views-embed-view()' if you're using it to place the view on your page otherwise it won't show up at all.
In Drupal 7, to figure out the node you're on, follow corneliusk's answer about making it your default argument. However, do NOT include the php tags, and it's just "arg" not "args" for d7. Ex:
if(arg(0) == 'node' && arg(1) != ''){
return arg(1);
}
else {
return "";
}

I have taxonomy terms hierarchy and I am using them as a filter in a view. It is showing hierarchy in the selectbox, but child terms appearing with hyphen(-). I have tried to drop hyphen in form alter, and I did, but I couldn't replace it blank space.
if ($form_id == 'views_exposed_form') {
$i = 0;
foreach ($form['field_region_tid']["#options"] as $op) {
foreach ($op->option as $key => $arr) {
if ($arr != null) {
$form['field_region_tid']["#options"][$i]->option[$key] = str_replace("-"," ", $arr);
}
}
$i++;
}
}
How can I put blank space at the beginning of the child options. Or should I do some other way?
Thanks!
From the form_id I get that it is a form generated by views. If so, the code inside the if condition never gets called because your module is executed after the views module due to the weight of both modules. To fix that:
Open your database manager (PhpMyAdmin in most cases) and open system table.
Then change the weight for your module to something larger than 10, because it is the default weight for the views module and you need you module to be executed after the views module.
Hope this helps... Muhammad.
if the problem is when your hook is called the answer lies in
hook_module_implements_alter()
but it is not as you say. Your code looks fine,
Have you tried
str_replace("-"," ", $arr);
?
I'm trying to allow users to update head titles and meta descriptions for each page. I thought that an easy way to achieve this would be to add a field to the 'Basic page' content type for the page title, then check if that field is not empty in html.tpl.php and if it is not, override $head_title with this user-defined value.
However, it appears that the $node variable is not available in html.tpl.php. Can anyone suggest a way for me to make this data available in this template file, or alternatively, alter $head_title before it is sent to html.tpl.php? Thanks for reading.
Taken in part from this thread that I found: http://drupal.org/node/1041768...
In your template.php, you can do the following:
function yourtheme_preprocess_html(&$variables) {
// If on an individual node page, add the node type to body classes.
if ($node = menu_get_object()) {
$variables['head_title'] = $node-> // find your cck field here
}
}
Bit messy, but would work:
if(arg(0) == 'node' && !empty(arg(1))) {
$node = node_load(arg(1));
}
However, you might prefer http://drupal.org/project/metatags_quick (an interrim module until the full http://drupal.org/project/metatags is finished).
How can I determine if the current Drupal page is a search results page?
Assuming clean URLs are on, this usually works
function MYTHEME_preprocess_page (&$vars, $hook) {
// ...
if ($hook == 'page' && arg(0) == 'search') {
// do search related stuff
}
}
inside your template.php.
Normal template suggestions work, too, such as using a page-search.tpl.php instead of page.tpl.php if that is also needed.
I made a customized template called node-mynode.tpl.php
Whenever a node of type mynode is requested, then node-mynode.tpl.php
is automatically used.
However, now user wants to see a specific menu block in this case.
Question:
How can I assign a block to a specific content type?
Hint: I have started to look at URL aliases with Pathauto.
I suspect one solution may lie in this direction.
In Drupal 6, you can configure the visibility settings of blocks. Click on the 'configure' link next to your block in the administrator backend and follow these steps -
1) Select the 'Show if the following PHP code returns TRUE (PHP-mode, experts only)' option under the 'Page specific visibility settings' tab.
2) Enter the following PHP code which checks the node type of the current node and returns TRUE accordingly -
<?php
if( arg(0) != 'node' || !is_numeric(arg(1)) )
{ return FALSE;
}
//load a fully-populated Drupal node object
$temp_node = node_load(arg(1));
if( $temp_node->type == 'mynode' ) //check the node type
{ return TRUE; //display block
}
?>
This should work....
you can use the context module
Give all of your mynode type nodes an automatic alias that starts with /mynode and use the page specific visibility settings for the block, showing only on the pages that start with /mynode/*.
I am currently using drupal 6 for a site I'm working on. I have a MYTHEME_preprocess_page() function that adds a few variables to the page.tpl.php template from the taxonomy and from a cck field. It was working correctly for a bit, and then the $vars['node'] is empty, but only for 2 content types. The 'node' variable is available to the preprocess_page function in other content types.
I thought it was a problem with using the following code, but when I remove all of this, the 'node' variable is still empty.
function mytheme_preprocess_node(&$vars, $hook) {
$function = 'mytheme_preprocess_node'.'_'. $vars['node']->type;
if (function_exists($function)) {
$function(&$vars);
}
}
Does anyone know of any gotchas or bugs that might be removing the 'node' variable? I can't seem to figure out where I'm going wrong. I'm at a loss.
Here is my complete mytheme_preprocess_page() function.
function mytheme_preprocess_page(&$vars, $hook) {
if ($hook == 'node' || $hook == 'page') {
if (is_object($vars['node'])) {
// grab the header image if it exists to make it avaialble to the content header
$vars['header_image'] = _mytheme_get_header_image($vars);
// get the taxonomy term to put in the content header
if (count($vars['node']->taxonomy) > 0) {
$vars['tax_term'] = "<div class=\"terms\">" . _mytheme_get_first_taxonomy_term($vars['node']->taxonomy) . "</div>";
}
// add the teacher's credentials to the content header
if ($vars['node']->field_credentials[0]['view'] != '') {
$vars['teacher_credentials'] = '<span class="teacher-creds">' . $vars['node']->field_credentials[0]['view'] . '</span>';
}
}
}
}
After going through and disabling modules one-by-one, I determined that the problem is related to the module, node_breadcrumb. A similar issue was filed here: http://drupal.org/node/616100#comment-2199374
In the 3rd comment, you'll see a link to another issue with a resolution
For others that run into this, I had the same issue as a result of using the jQuery UI module. Disabling and re-enabling fixed it, and I could not track down the specific issue, but it appeared to be related to $static variables in some path check functions.
To others that stumble their way into here, I suggest you pull some of the more obvious modules right out of the module folder on your dev setup, see if things change, and then put them back in there until you figure it out.
Another option is to search for instances of _preprocess_page(, $variables['node'] and $vars['node'] to see if some contributed code is unwittingly unsetting a node when it shouldn't be.
