Delete a field programatically from a content type

<?php

field_delete_field($field_name);
field_purge_batch();

// note: only run this if you need the field deleted immediately!! otherwise it will just be deleted the next time the cron runs

?>

If you manually delete fields from the database, many things can go wrong. For example, hook_field_delete will not be called and one of your modules might fail and crash the site.

What is contextual filter

Contextual filters work similarly to regular filters, but there is one important difference. Instead of setting a filter value manually, the value is fetched from variables sent programmatically to the view

The classic example of how contextual filter values are provided to views is by the view path. If a view has the path example.com/my-view, the URL example.com/my-view/story/22 will call the view along with two values for contextual filters (in this casestory and 22). But there are more ways of providing contextual filter values
