Module development and code questions

Hi to all,
I provided a patch for the webform module here (version 7.x-4.22, I am working with Drupal 7.69), and am trying to provide a test with it.

I'm developing a custom module with an image field.

Where can I set the following HTML attribute to my custom field?

<input type=file
       accept="image/*"
       capture=environment>

I have created the image field and i'm able to process some OCR with an external library uploading the image but I need to use webcam instead and I can't find the way to set the "capture=enviroment" tag to my input form in the field widget file.

Thank you

Hi,

I'm devolping a Drupal 8 module for employee check-in / check-out time based on QR code reading / decode with an external php library.

I've installed khanamiryan/qrcode-detector-decoder with composer.

Now I need to call the QrReader class inside MyModuleFieldDecoderWidget.php but I got allways an error message like this:

Error: Class 'Drupal\FieldQrDecoder\Plugin\Field\FieldWidget\QrReader' not found.

I've tried with

use Khanamiryan;

and also

<a href="/print/pdf/block_content/6" class="print__link print__link--pdf">View PDF</a>

How to change "View PDF" in this link, which is generated by Module Entity Print, for my own words (I would like to write there another words)?

Hi,

I have been asked to work on website personalization. Basically I have to save the selections that the logged in user made in the website, so that when they log in again they dont have to make the same selections again. I have to all this programmatically.

Could you please help me how should I go about it? Any resources would help.

Thanks,

I have a custom module that builds a custom menu depending on an attribute of the node for a basic page. If $nid = 10, then a custom-menu-10 needs to appear in a region for that page. If $nid = 11, then a custom-menu-11 will appear in that same region. In D7, we just threw the custom menu into a menu_tree_all_data and used $variables['my_custom_menu'] to place the html in page.tpl.php.

To learn more in the new D8 theme API, I've created a custom block in mymodule which has the code I need to determine the node-id() and instantiate the custom menu.
