如何在“用户”个人资料上添加字段？例如国家/地区，年龄等

您需要使用show_user_profile,edit_user_profile,personal_options_update和edit_user_profile_update钩子.

您可以使用以下代码在"用户"部分添加其他字段

在"编辑用户"部分中添加其他字段的代码:

 add_action( 'show_user_profile', 'extra_user_profile_fields' );
add_action( 'edit_user_profile', 'extra_user_profile_fields' );

function extra_user_profile_fields( $user ) { ?>
    <h3><?php _e("Extra profile information", "blank"); ?></h3>

    <table class="form-table">
    <tr>
        <th><label for="address"><?php _e("Address"); ?></label></th>
        <td>
            <input type="text" name="address" id="address" value="<?php echo esc_attr( get_the_author_meta( 'address', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("Please enter your address."); ?></span>
        </td>
    </tr>
    <tr>
        <th><label for="city"><?php _e("City"); ?></label></th>
        <td>
            <input type="text" name="city" id="city" value="<?php echo esc_attr( get_the_author_meta( 'city', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("Please enter your city."); ?></span>
        </td>
    </tr>
    <tr>
    <th><label for="postalcode"><?php _e("Postal Code"); ?></label></th>
        <td>
            <input type="text" name="postalcode" id="postalcode" value="<?php echo esc_attr( get_the_author_meta( 'postalcode', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("Please enter your postal code."); ?></span>
        </td>
    </tr>
    </table>
<?php }
 

用于在数据库中保存额外字段详细信息的代码:

 add_action( 'personal_options_update', 'save_extra_user_profile_fields' );
add_action( 'edit_user_profile_update', 'save_extra_user_profile_fields' );

function save_extra_user_profile_fields( $user_id ) {
    if ( !current_user_can( 'edit_user', $user_id ) ) { 
        return false; 
    }
    update_user_meta( $user_id, 'address', $_POST['address'] );
    update_user_meta( $user_id, 'city', $_POST['city'] );
    update_user_meta( $user_id, 'postalcode', $_POST['postalcode'] );
}
 

关于该主题的一些博客文章也可能会有所帮助:

• 添加和使用自定义用户配置文件字段
• 向WordPress用户配置文件中添加其他字段

You need to use the show_user_profile, edit_user_profile, personal_options_update, and edit_user_profile_update hooks.

You can use the following code for adding additional fields in User section

Code for adding extra fields in Edit User Section:

add_action( 'show_user_profile', 'extra_user_profile_fields' );
add_action( 'edit_user_profile', 'extra_user_profile_fields' );

function extra_user_profile_fields( $user ) { ?>
    <h3><?php _e("Extra profile information", "blank"); ?></h3>

    <table class="form-table">
    <tr>
        <th><label for="address"><?php _e("Address"); ?></label></th>
        <td>
            <input type="text" name="address" id="address" value="<?php echo esc_attr( get_the_author_meta( 'address', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("Please enter your address."); ?></span>
        </td>
    </tr>
    <tr>
        <th><label for="city"><?php _e("City"); ?></label></th>
        <td>
            <input type="text" name="city" id="city" value="<?php echo esc_attr( get_the_author_meta( 'city', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("Please enter your city."); ?></span>
        </td>
    </tr>
    <tr>
    <th><label for="postalcode"><?php _e("Postal Code"); ?></label></th>
        <td>
            <input type="text" name="postalcode" id="postalcode" value="<?php echo esc_attr( get_the_author_meta( 'postalcode', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("Please enter your postal code."); ?></span>
        </td>
    </tr>
    </table>
<?php }

Code for saving extra fields details in database:

add_action( 'personal_options_update', 'save_extra_user_profile_fields' );
add_action( 'edit_user_profile_update', 'save_extra_user_profile_fields' );

function save_extra_user_profile_fields( $user_id ) {
    if ( !current_user_can( 'edit_user', $user_id ) ) { 
        return false; 
    }
    update_user_meta( $user_id, 'address', $_POST['address'] );
    update_user_meta( $user_id, 'city', $_POST['city'] );
    update_user_meta( $user_id, 'postalcode', $_POST['postalcode'] );
}

There are also several blog posts available on the subject that might be helpful:

• Adding and using custom user profile fields
• Adding Extra Fields to the WordPress User Profile

高级自定义字段专业插件将使您无需任何编码即可将字段添加到用户配置文件

The Advanced Custom Fields Pro plugin will allow you to add fields to user profiles without any coding.

您最好使用 get_user_meta (而不是 get_the_author_meta ):

 function extra_user_profile_fields( $user ) {
    $meta = get_user_meta($user->ID, 'meta_key_name', false);
}
 

You'd better use get_user_meta (instead of get_the_author_meta):

function extra_user_profile_fields( $user ) {
    $meta = get_user_meta($user->ID, 'meta_key_name', false);
}
