将自定义字段的多个值存储在一个用户元键中

时间：2018-08-27 作者：Alief

我在用户配置文件中添加了一些自定义字段。这是“出生日期”。

“有”month_of_birth“，”day_of_birth“，”year_of_birth“。

如何将它们存储在一个元密钥中（\'birth_date\') ?

以下是自定义字段的代码：

// ADD EXTRA PROFILE FIELD - BIRTH DATE

add_action( \'show_user_profile\', \'birthdate_show_extra_profile_fields\' );
add_action( \'edit_user_profile\', \'birthdate_show_extra_profile_fields\' );

function birthdate_show_extra_profile_fields( $user ) { ?>
<h3 class="birthdate-info">Date of Birth</h3>
<table class="form-table">
    <tr>
        <th><label for="birth_date">Date of Birth</label></th>
        <td width="30%">
            <select name="month_of_birth" id="month_of_birth">
                <?php
                    $_value = trim( get_user_meta( $user->ID, \'month_of_birth\', true ) );
                    foreach ( array(
                        \'not-selected\' => \'\',
                        \'january\' => \'January\',

// SAVE EXTRA PROFILE FIELD - BIRTH DATE

add_action( \'personal_options_update\', \'birthdate_save_extra_user_profile_fields\' );

function birthdate_save_extra_user_profile_fields( $user_id ) {

if ( !current_user_can( \'edit_user\', $user_id ) )
    return false;
update_user_meta( $user_id,\'year_of_birth\', $_POST[\'year_of_birth\'] );
}

UPDATE 2:短代码-

function user_birthdate_info_shortcode() {
if(is_user_logged_in()) {
    $user_id = get_current_user_id();
    $birth_date = get_user_meta($user_id, \'birth_date\', false);

foreach($birth_date as $key => $value){
echo $value[\'month\'] . \'&nbsp;\' . $value[\'day\'] . \'&nbsp;\' . $value[\'year\'];
}
}}
add_shortcode(\'currentuser_show_birthdate_info\', \'user_birthdate_info_shortcode\');

“有”month_of_birth“，”day_of_birth“，”year_of_birth“。

如何将它们存储在一个元密钥中（\'birth_date\') ?

如果要用一个元键替换所有三个元键，则可以保存birth_date 元作为array, 所以值应该是这样的：

array(
    \'month\' => \'august\',
    \'day\'   => \'27\',
    \'year\'  => \'2018\'
)

Here are the steps:

<在birthdate_show_extra_profile_fields(), 检索birth_date 元值如下：

function birthdate_show_extra_profile_fields( $user ) {
    // Get the birth date, which is an array of month, day, and year.
    $birth_date = (array) get_user_meta( $user->ID, \'birth_date\', true );
    ?>

然后更换name 下拉菜单的。select字段），并替换用于检索个人生日、日期和年份的代码：

对于出生月份菜单：

<select name="month_of_birth" id="month_of_birth"> <!-- before -->
<select name="birth_date[month]" id="month_of_birth"> <!-- after -->

$_value = trim( get_user_meta( $user->ID, \'month_of_birth\', true ) ); // before
$_value = isset( $birth_date[\'month\'] ) ? $birth_date[\'month\'] : \'\'; // after

对于出生日菜单：

<select name="day_of_birth" id="day_of_birth"> <!-- before -->
<select name="birth_date[day]" id="day_of_birth"> <!-- after -->

$_value = trim( get_user_meta( $user->ID, \'day_of_birth\', true ) ); // before
$_value = isset( $birth_date[\'day\'] ) ? $birth_date[\'day\'] : \'\'; // after

对于出生年份菜单：

<select name="year_of_birth" id="year_of_birth"> <!-- before -->
<select name="birth_date[year]" id="year_of_birth"> <!-- after -->

$_value = trim( get_user_meta( $user->ID, \'year_of_birth\', true ) ); // before
$_value = isset( $birth_date[\'year\'] ) ? $birth_date[\'year\'] : \'\'; // after

然后使用此选项保存birth_date 元值：

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

    // Make sure we have a valid POSTed data, and if yes, then
    // sanitize/clean each array item.
    $birth_date = isset( $_POST[\'birth_date\'] ) ?
        array_map( \'sanitize_text_field\', $_POST[\'birth_date\'] ) : array();

    update_user_meta( $user_id, \'birth_date\', $birth_date );
}

更新您可以检索保存的birth_date 元值如下：

// Note that the last/third parameter is TRUE and not FALSE.
$birth_date = get_user_meta( $user_id, \'birth_date\', true );

echo $birth_date[\'month\']; // e.g. august
echo $birth_date[\'day\'];   // e.g. 27
echo $birth_date[\'year\'];  // e.g. 2018

如果希望月份名称以大写开头，请应用ucfirst() 在月份名称上，如下所示：

echo ucfirst( $birth_date[\'month\'] ); // e.g. August

所以你的user_birthdate_info_shortcode() 可以改写为：

function user_birthdate_info_shortcode() {
    if(is_user_logged_in()) {
        $user_id = get_current_user_id();
        $birth_date = get_user_meta($user_id, \'birth_date\', true);

        echo ucfirst( $birth_date[\'month\'] ) . \'&nbsp;\' . // apply ucfirst()
            $birth_date[\'day\'] . \'&nbsp;\' . $birth_date[\'year\'];
    }
}

<小时>Alternatively, just save the month name (e.g. August) instead of its slug/key (e.g. august). 所以在birthdate_show_extra_profile_fields() 函数，更改如下：（需要重新缩进代码）

foreach ( array(
    \'not-selected\' => \'\',
    \'january\' => \'January\',
    \'february\' => \'February\',
    \'march\' => \'March\',
    \'april\' => \'April\',
    \'may\' => \'May\',
    \'june\' => \'June\',
    \'july\' => \'July\',
    \'august\' => \'August\',
    \'september\' => \'September\',
    \'october\' => \'October\',
    \'november\' => \'November\',
    \'december\' => \'December\',
) as $value => $label ) :

收件人：

foreach ( array(
    \'\',
    \'January\', \'February\', \'March\',     \'April\',   \'May\',      \'June\',
    \'July\',    \'August\',   \'September\', \'October\', \'November\', \'December\',
) as $label ) :
    $value = $label; // use the label as the value

所以你的user_birthdate_info_shortcode() 可以改写为：

function user_birthdate_info_shortcode() {
    if(is_user_logged_in()) {
        $user_id = get_current_user_id();
        $birth_date = get_user_meta($user_id, \'birth_date\', true);

        echo $birth_date[\'month\'] . \'&nbsp;\' . // ucfirst() not necessary
            $birth_date[\'day\'] . \'&nbsp;\' . $birth_date[\'year\'];
    }
}

您可以将这些字段保存在单用户元字段中，如下所示：


 // SAVE EXTRA PROFILE FIELD - BIRTH DATE
add_action( \'personal_options_update\', \'birthdate_save_extra_user_profile_fields\' );
add_action( \'edit_user_profile_update\', \'birthdate_save_extra_user_profile_fields\' );

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

    // Use this fields to save the selected the options
    update_user_meta( $user_id,\'month_of_birth\', $_POST[\'month_of_birth\'] );
    update_user_meta( $user_id,\'day_of_birth\', $_POST[\'day_of_birth\'] );
    update_user_meta( $user_id,\'year_of_birth\', $_POST[\'year_of_birth\'] );


    $date_of_birth = array();
    $date_of_birth[] = sanitize_text_field( $_POST[\'year_of_birth\'] );
    $date_of_birth[] = sanitize_text_field( $_POST[\'month_of_birth\'] );
    $date_of_birth[] = sanitize_text_field( $_POST[\'day_of_birth\'] );

    // Use this fields to show and perform any operations
    // Delete the birth_date if all fields are empty.
    if( empty( $date_of_birth ) && count($date_of_birth) == 0 )
        delete_user_meta( $user_id, \'birth_date\' );
    else
        update_user_meta( $user_id, \'birth_date\', join(\'/\', $date_of_birth ) ); 
}

注意：代码中的注释很重要。
