Module development and code questions

Hi,

For my website, I want to give users an option to save their selections before logging out. Once they click the logout button, I want to open a modal pop up which gives them 2 choices, Save or Cancel.

If they select Save, then their selections would be saved in the database.

How could I do so in drupal? If there are any examples online, please let me know.

Thanks

I am trying to import an xlsx import into my site. I already have the feed setup, but there isn't a way to build a composite unique field (like for example, if any value in column 1 and any value in column 2 together (but not separately) exist, don't import. Is there a way I can do this? I'm trying to avoid building a custom parser if I can use built in feeds to do it. 

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)?
