Customize Search Form Text Input Field Name

问题

I want to change the default name 's' to something else for the search widget of wordpress. So, basically I will need to change the widget template and the handler that reads the GET input. Can you please help me finding those two place quickly please? Thanks.

This is the solution I've used, where 'q' is the name of the search field:

function my_query_vars( $public_query_vars ) {
    if ( isset( $_GET['q'] ) && ! empty( $_GET['q'] ) ) {
        $_GET['s'] = $_GET['q'];
    }

    return $public_query_vars;
}

add_filter( 'query_vars', 'my_query_vars' );

Searched on google "get search form wordpress"

taken from here: http://codex.wordpress.org/Function_Reference/get_search_form

Drop this function in your theme's functions.php

function my_search_form( $form ) {

        $form = '<form role="search" method="get" id="searchform" action="' . home_url( '/' ) . '" >
        <div><label class="screen-reader-text" for="s">' . __('Search for:') . '</label>
        <input type="text" value="' . get_search_query() . '" name="s" id="s" />
        <input type="submit" id="searchsubmit" value="'. esc_attr__('Search') .'" />
        </div>
        </form>';

        return $form;
    }

    add_filter( 'get_search_form', 'my_search_form' );
