I want to be able to show or hide a text snippet on a node based on whether or not it was tagged with a specific taxonomy term.
Something along the lines of:
if (term('green')) {
echo"this is green";
}
else {
echo "not green";
}
What is the Drupal way of doing this?
Assuming from your example that you're working from inside of node.tpl.php, and that you have a single very specific term in mind:
You can access $taxonomy->taxonomy_term_YourTermID from within your node.tpl.php file, and test based on that.
If you'd like a more abstract solution, I'd recommend installing the devel module and building a function in your template.php files based on what shows up under the 'Devel' tab in the relevant node.

I have views that shows profiles of my site within a block.
Now, I am trying to alter the title of that block through hook_block_view_MODULE_DELTA_alter.
here is the code of my custom module:
<?php
function homepagefilter_block_view_views_new_users_alter(&$data, $block) {
$data['subject'] = t('New title of the block');
}
I doen't see any effect on the block title...
Why is that?
try hook_block_view_alter().
function homepagefilter_block_view_alter(&$data, $block){
if($block->delta == 'BLOCKID'){
print_r($block);
print_r($data['subject']);
}
}
The deltas of blocks created by the Views module looks like "[view_name]-[display_name]", and the display name is something like "[type]_[number]" by default. So that means the full delta for your block is probably something like "new_users-block_1". However, you can't implement homepagefilter_block_view_views_new_users-block_1_alter(), because you can't use a hyphen in a function name. The blocks Menu module creates has a similar problem (see this issue). As Behzad says, you'll have to implement the generic hook_block_view_alter() hook for now.
I have several custom content types and in one specific one I need to offer two fields, one for the href for a link, and one for the text of a link this way I can build and style it with minimal user involvement of the HTML/CSS. I also have a custom node.tpl for this content type. My problem is that drupal throws divs around each field I create that aren't in my template file for this content type (node-custom.tpl) and I can't put the href for a link with divs around it inside google.co.uk</div>"> See my problem. Maybe I'm doing this all wrong so any other ideas are welcome.
Please note I'm trying to create this site with minimum involvement of HTML/CSS access for the user. I'm aware I could hand code the link in the field.
The easiest way to do this would be to use a preprocess function in your template.php file and build the link up manually:
function mytheme_preprocess_node(&$vars) {
$node = $vars['node'];
if ($node->type = 'my_type') {
$uri = $node->field_name_of_link_field[LANGUAGE_NONE][0]['value'];
$text = $node->field_name_of_display_text_field[LANGUAGE_NONE][0]['value'];
$vars['my_link'] = l($text, $uri); // Using Drupal's l() function to render a link
}
}
Then in your node template file you'll have access to the variable $my_link which you can output anywhere, and will contain the correct HTML for the link. Finally, go to the "Manage Display" page for your content type and set the display of the two fields you no longer need to output to 'Hidden'.
There are other ways so if that's no good let me know
EDIT
Just to add, I think the easiest way to do this would actually be to install the Link module and use the provided field type instead of the two other fields you're currently using.
I have created a custom field on a content type in Drupal 7 which I need to display outside of the node, in a separate area on the page.
Similar to how the $title variable works (in which you can place this where you like in the page.tpl.php file) I would like to be able to create another variable called $subtitle which would call the data from the current node and allow me to print out the variable in an area on the page.tpl.php file.
I've seen a view examples seeming to use views and blocks to accomplish this task, but that seems a bit excessive and wondered if there was an easier way.
There is an easier way, you do need to bear in mind though that not every page is a node page, and not every node page will be of the right content type so you should be selective. Just add this to your theme's template.php file:
function mytheme_preprocess_node(&$vars) {
$node = $vars['node'];
if ($node->type == 'my_type') {
$vars['subtitle'] = $node->field_my_field[LANGUAGE_NONE][0]['value'];
}
}
Then in page.tpl.php you should do something like this:
if (isset($subtitle)) :
echo $subtitle;
endif;
Make sure you clear your caches (at admin/config/development/performance) once you've implemented the hook in template.php or Drupal won't pick it up.
I've just discovered that if you want to alter a specific page (or group of pages) all you need is to add templates file to the core templates. For instance, I need to theme my /helloword page using a page--helloworld.tpl.php and node--helloworld.tpl.php template files.
Now all I get is a blank screen so I tried to write a preprocess function that adds support for custom theme files like:
<?php
/**
* Adding or modifying variables before page render.
*/
function phptemplate_preprocess_page(&$vars) {
// Page change based on node->type
// Add a new page-TYPE template to the list of templates used
if (isset($vars['node'])) {
// Add template naming suggestion. It should alway use doublehyphens in Drupal7.
$vars['template_files'][] = 'page--'. str_replace('_', '-', $vars['node']->type);
}
}
?>
I see no syntax error but I still get a blank screen. Still no luck
Is someone able to figure out what's wrong in the code/routine?

I think there's a tiny bit of confusion here: a template file named node--type.tpl.php will automatically be called for any node which has the type type...you don't need to add the template suggestions in yourself.
There is one caveat to this, you have to copy the original node.tpl.php to your theme folder and clear your caches otherwise Drupal won't pick it up.
Also you don't want to use the phptemplate_ prefix...rather you want your function to be called MYTHEMENAME_preprocess_page.
Your code to add the page template based on the node type looks spot on, see if you still have the problem after you change your function name and clear the caches.
Hope that helps :)
I have two content types, book and chapter. Each chapter node contains a node reference of the book to which it belongs. I have created a view which displays the title of each chapter for a given book. Within the view, the title field has been configured to link to its node.
All works well. I am now interested in updating the view to not display a link to a chapter's node when the chapter's body is empty. Thus this view would display a list of chapter titles for a book and link only to those chapters that have a body.
Can this be accomplished using out of the box Views functionality? If not, how would something like this be accomplished?
Thanks.
I'd use the Views Custom Field module to implement your custom logic. It allows you to grab the data fetched by Views and manipulate it at will with PHP. Very handy.
I'm answering my own question because my response to ceejayoz is poorly formatted.
What I did to accomplish this was to first download and enable views_customfield. Second, I placed Title and Body fields within the view, both excluded from display. Third, within a Customfield: PHP code field I placed the following code:
<?php
if (strlen(trim($data->node_revisions_body)) == 0) {
return $data->node_title;
} else {
return l($data->node_title, drupal_get_path_alias('node/' . $data->nid));
}
?>
There's also this clever workaround which allows you to achieve this very easily:
Add 2 title fields one with link and one with no link, and make both
them exclude from display.
Add body field,
In No result behavior put title with no link replacement token to
it.
In Rewrite results behavior put title with link replacement token to
it.
Tick hide if empty.
