drupal - getting all ImageFields associated with a node -

-

How do I get all the image fields associated with the content type on a full node without knowing the field names? Just out of curiosity, can we get all the fields of a specific type?

I am developing a module that requires image zones related to a specific node and I am using hook_node_view to obtain node data.

I have already seen the following post and it was very relevant but I was having difficulty understanding it.

This can be done by checking all the fields of your content type & amp; Check your "Type" field

If the field is an image then you can render it

c++ - Redefined variable in the other module -

-
Why do we redefine the variable in other modules, so it is OK to add this module together? I have written two modules main.cpp and module.cpp as the following: // - main.cpp-- // # include & lt; Stdio.h & gt; Int main () {int i = 5; Printf ("I value is% d", i); } and // - module.cpp - // int i = 7; I am now compiling and adding g ++ as the following: g ++ -c main .cpp g ++ - c module. cao g ++ - o bin main.o module.o and it's okay. But I hope the compilation will be successful, while the linker will throw an exception like redefining varaible when I'm running .bin output then the value of i is 5 . UPD: I understand that if we use I as global variable module main.cpp that linker will throw an error. The main variable in the function is a local variable of i function. It is not visible and is present outside the function is. Consider the following example #include & lt; Iostream & gt; Int i = 3; Int main (...
