同样，如果您知道如何添加文本字段，您也知道如何添加任何其他表单字段，例如：

显示字段：

//hooks
add_action( \'show_user_profile\', \'Add_user_fields\' );
add_action( \'edit_user_profile\', \'Add_user_fields\' );

function Add_user_fields( $user ) { ?>

    <h3>Extra fields</h3>
    <table class="form-table">
        <tr>
            <th><label for="text">text</label></th>
            <td>
                <?php 
                // get test saved value
                $saved = esc_attr( get_the_author_meta( \'user_text\', $user->ID ) );
                ?>
                <input type="text" name="user_text" id="user_text" value="<?php echo $saved; ?>" class="regular-text" /><br />
                <span class="description">Simple text field</span>
            </td>
        </tr>

        <tr>
            <th><label for="dropdown">dropdown Select field</label></th>
            <td>
                <?php 
                //get dropdown saved value
                $selected = get_the_author_meta( \'user_select\', $user->ID ) ); 
                ?>
                <select name="user_select" id="user_select">
                    <option value="value1" <?php echo ($selected == "value1")?  \'selected="selected"\' : \'\' ?>>Value One label</option>
                    <option value="value2" <?php echo ($selected == "value2")?  \'selected="selected"\' : \'\' ?>>Value Two label</option>

                <span class="description">Simple text field</span>
            </td>
        </tr>
    </table>
<?php }

add_action( \'personal_options_update\', \'save_user_fields\' );
add_action( \'edit_user_profile_update\', \'save_user_fields\' );

function save_user_fields( $user_id ) {

    if ( !current_user_can( \'edit_user\', $user_id ) )
        return false;

    //save text field
    update_usermeta( $user_id, \'user_text\', $_POST[\'user_text\'] );

    //save dropdown
    update_usermeta( $user_id, \'user_select\', $_POST[\'user_select\'] );
}

将其添加到主题中function.php

add_action( \'show_user_profile\', \'Add_user_fields\' );
add_action( \'edit_user_profile\', \'Add_user_fields\' );
function Add_user_fields( $user ) { ?>
    <table class="form-table">
        <tr>
            <th><label for="dropdown">Activate/Deactivate User</label></th>
            <td>
                <?php 
                //get dropdown saved value
                $selected = get_the_author_meta(\'pmpro_email_confirmation_key\', $user->ID); //there was an extra ) here that was not needed 
                ?>
                <select name="user_select" id="user_select">
                    <option value="validated" <?php echo ($selected == "validated")?  \'selected="selected"\' : \'\' ?>>Activate</option>
                    <option value="notvalidated" <?php echo ($selected == "notvalidated")?  \'selected="selected"\' : \'\' ?>>De-Activate</option>
                </select>
            </td>
        </tr>
    </table>
<?php } 

add_action( \'personal_options_update\', \'save_user_fields\' );
add_action( \'edit_user_profile_update\', \'save_user_fields\' );

function save_user_fields( $user_id ) {
    if ( !current_user_can( \'edit_user\', $user_id ) ){
        return false;
    }
    //save dropdown
    update_usermeta( $user_id, \'pmpro_email_confirmation_key\', $_POST[\'user_select\'] );
    }
?>
