pub fn get_form_values<'a>(
    form: &str, 
    elements: &'a [&str]
) -> HashMap<&'a str, String>

Expand description

Loop through an array of named form elements returning their values in a HashMap.

If loading values from an encoded form, use get_encoded_form_values.

Example

use goose_eggs::drupal::{get_form, get_form_values};

// For this example we grab just a subset of a real Drupal form, enough to demonstrate. Normally
// you'd use the entire html snippet returned from [`validate_and_load_static_assets`].
