Insert code from module to .tpl I'm trying to insert a code (a button) from a module to a specific place in a view (between the filters and the array).
Does anyone have an idea of how it can be done ?

Thanks
Copy sites/all/modules/views/theme/views-exposed-form.tpl.php into your theme's template folder.  Rename it to views-exposed-form--YOURVIEWMACHINENAME.tpl.php and clear caches.  You should be able to put your button after the exposed filter content.
