I've been looking for a hook in drupal 7 that allows me to send an http request when the user moves a taxonomy term in or out of another taxonomy. For example:
I want to be able to 'detect' when I take World War in or out of This is War.
I hope you can help me, and sorry for the ignorance.
For anyone trying to achieve this, I found a way to do it. Not sure if it's the only one there is, but here it goes:
In your custom .module file, implement a hook with the following form Id
function mymodule_form_taxonomy_overview_terms_alter(&$form, $form_state)
Then, you can add a #submit element like this:
$form['#submit'][] = 'my_custom_handler';
Now, you can define my_custom_handler as follows
function my_custom_handler($form, &$form_state)
And my_custom_handler will execute every time user saves changes in the specific form. If you need to get the terms in the my_custom_handler method you could somehow mimic the code in the source taxonomy module.
I hope someone finds this useful
For "detect", hook_taxonomy_term_update may help you.

I know this sounds like a big ask, but I'm assuming someone else has already done this and has a simple answer because it seems like an obvious use case.
Twilio has a sample app available on GitHub for their video service. Unfortunately, I don't know much about react, so I was able to make a couple of little changes, but this one has me stumped.
The code is called: Twilio / twilio-video-app-react
https://github.com/twilio/twilio-video-app-react
When you launch the code to enter a video room, you are presented with a form to enter your name and the name of a video room. I need to remove that room name input field and replace it with a hidden variable that was provided in the URL. In other words:
Get a room name variable that was passed as a query parameter on the URL
Make sure the room name is "safe" (alphanumeric) and then put it into a hidden variable in the form
Remove the visible input field (room name) from the form
That would take me two minutes in PHP, and it's probably really easy in react as well, but I can't figure it out. Hope someone can point me in the right direction.
I am trying to work out if a visitor is entering / first page they visit is site.com/life
As we need a change a few things like:
CSS
Audio Playing in Background
etc etc.
I am wondering is their a function that allows us to work out if a path was the first entry point for that visitor?
I was thinking we could check to see if their is a back history but not sure if this would work?
Any advice would be great.
If your app is using react-router, you can access the history object and see where the oldest entry is.
Here I want to know how to get the field values of my custom content type 'mypop'. I tried all methods in google but I don't know how to use, for example i tried function node_load, I can't able to know where to write this function, what are the parameters and tried EntityFieldQuery too. Can I know the how to do it in brief explaination.
Thanks in Advance.
Definitely a very broad question. Assuming you have the content type 'mypop' created already, think the easiest steps for you would be to:
Make sure you create some content of that content type
Customize the "Manage Display" on that content type and make sure the fields you want are set to visible there
Once you do this, those fields should be visible when you view the nodes of that content type already. If you want to further customize the view, you should probably customize the template file for that specific content type (there's other options but trying to keep this as simple as possible).
To do this, copy the "node.tpl.php" file you'll find on the modules/node folder to your theme templates folder and change it's name to be "node--mypop.tpl.php".
That way, you'll override Drupal's default display template for that specific content type only. Now you can basically tweak it into anyway you want.
Hope this helps!
Thanks a lot Alberto. Its working now! I have another issue too, it also got cleared and now its working fine !Another issue is javascript called automatically when I open views edit for other contents. Now by doing overriding this template file, it also gets cleared. Thank you !
node_load take node id. So in order to use noad_load() function, you should first retrieve node ids. Better if you use noad_load_multiple().
// Query all of the nids of a particular content type.
$nids = db_select('node', 'n')
->fields('n', array('nid'))
->condition('type', 'Article', '=')
->execute()
->fetchCol();
// Get all of the article nodes.
$nodes = node_load_multiple($nids);
You can see the result by calling print_r($nodes). Just write a normal function in you .module file or .inc file. Call it anywhere, your choice. say, in menu callback.
I would like to style a couple of elements using a filter to decipher if it should be yellow or red.
I understand filters should not carry logic operations in them as such so am guessing a service is the first port of call before i create any filter for it.
I am leveraging data from a backend (still a bit unsure of the Backend model here, but know I can leverage certain objects to obtain the data needed for working on) I mostly need to know if i`m on the right path by using a service to control the logical outcome and then a filter to provide 'filtration' of that outcome.
BTW: sorry, im waiting for my project to checkout from SVN at mo so cannot provide a skeleton attempt.
Will do in a bit though .....
Any advice before hand will be much appreciated
:) Gruffy - thanks for reading
You can directly set the class attribute if you want, so your filter can simply return the CSS class to apply:
<p class="{{'foo'|myFilter}}">Foo</p>
Here's a fiddle showing what I mean.
First time poster here, I'm a designer not skilled at all with php and I have a small issue I don't seem to be able to solve. I'm making a site in drupal 7 using a sub theme on zen.
Btw this is a great CMS, even though people say it's really more a developers CMS. I have no trouble to do what I need using views, rules, display suite etc. So a big thank you for all the developers out there making this such a good CMS. But for this apparently simple problem... no module will help me (I think) and I'm kinda stuck.
So here it is: I'd like to add a subtitle next to the title in all my pages.
So what I did was to add a custom field into the content type basic page (machine name: field_sub_title) which is a simple text field.
I uncommented the following line in my template.php
function mytheme_preprocess_page(&$variables, $hook) {
$variables['sub_title'] = t('field_sub_title');
}
Now my question is how do I load the content of my custom field into that variable?
I know i need to change the second part, but I don't have a clue as into what I need to change this.
Displaying the variable into the the page.tpl.php is something I know about so I only need help with the first part.
{EDIT}
Ok I found how to do this :)
I was looking for a solution in the wrong place. I don't need to change any thing in the template.php file.
Just needed to add this bit of code into my page.tpl.php:
<?php
print $node->field_sub_title['und'][0]['value'];
?>
So I'm posting this here for other Drupal newbies struggling with this....
Your solution may work for now, but there may be a more Drupal-y way to handle a problem like this. If you haven't noticed any problems yet, you may find one or more of the following issues down the road:
Someone who doesn't know php or Drupal theming may need to change the way this works.
If you're like me, you may forget where exactly in code this was implemented.
You may see superfluous markup and/or errors on nodes (content) that do not have this sub-title field (ie. event content not having a sub-title field while basic pages and news articles do).
When you add a field to a content type, it will automatically appear anytime content in that content type is displayed. You should be able to add the sub-title field for your page, event or whatever else you need and have it automatically appear in the markup.
You can 'manage display' of a content type to drag and drop the order for fields to appear. You could take it a step further by using a module like Display Suite to add formatting or layout per-content type.
If you feel like this isn't good enough and the markup for the subtitle must be at the same level as the page title (which is rare), at least add an if statement to make your code check to see if the variable is present before trying to print it. I'd also add a new variable and comments for code readability.
<?php
$subtitle = $node->field_sub_title['und'][0]['value'];
if($subtitle){
print $subtitle;
}
?>
Consider using field_get_items or field_view_value, or at least use the LANGUAGE_NONE constant instead of 'und'
See https://api.drupal.org/api/drupal/modules%21field%21field.module/function/field_get_items/7 and https://api.drupal.org/api/drupal/modules!field!field.module/function/field_view_value/7
This has the added benefit of reducing the number of potential security holes you create.
