Module development and code questions

Hi all,

Is there is any way to call Batch API with in hook_ENTITY_TYPE_insert() in Drupal 8?

Hi, I have a website running on Drupal 7.32 on a linux environment, I have a issue with my website. In my file system I have mentioned tmp folder which is in my root directory to be the temp folder.  In one of the section on my website I need to upload certain files for end users to download. Files does not get uploaded in Drupal unless I give full 777 access to tmp folder. I tried giving only write access to tmp folder, but still the file does not get uploaded. It necessarily requires execute permission for files to be uploaded. 

Hello everyone,

I'm not a developer by trade and therefore I don't have a ton of access to a community of experienced developers. I'm posting here to access such brain power. :)

I'm trying to set up responsive images on my site.  I’ve just added the Breakpoints module. Drupal 7. 

Need to add Image styles via the cog on the right hand side on manage display with editing a content type.  The cog shows for new fields but I can’t see how to add to existing fields.

Any idea?  

I'm using Display Suite for D7 content type of Doctor so that my customer can order its fields into different display modes.
