Question

我具有自定义功能，该功能汇总了wordpress数据库中自定义字段的值。

这些值已正确汇总，并显示如下： 1500.3€

如何在小数点后添加零，以便总和显示如下 1500.30€

我想我需要使用number_format（）格式化$ sum，但是我不确定100％如何在我的函数中使用number_format。

它应该看起来像这样：

number_format($sum, 2, '.', '');

但是我可以将上面的内容坚持我的功能吗？

自定义功能：

function kd_shortcode_group_progress($atts, $content = null) {
 extract( shortcode_atts( array(
    'challenge' => '0',
    'group' => '1',
), $atts ) );

global $wpdb;
$prefix = $wpdb->prefix;
global $kd_table;
$table = $prefix."postmeta";
$table2 = $prefix."posts";

$sum = 0;

$sql = "SELECT `post_id` FROM `".$table."` WHERE `meta_key` = 'wpcf-haaste_valmis' and `meta_value` = '".$challenge."';";
$people = $wpdb->get_results($sql);

$sql4 = "SELECT `id` as `post_id` FROM `".$table2."` WHERE `post_type` = 'osallistuja' and `post_title` = '".$group."';";
$ids = $wpdb->get_results($sql4);

$pageId = '';
foreach ($ids as $i => $id) {
    $people[] = $ids[$i];
}

foreach ($people as $i => $val) {
    $pid = $val->post_id;

    $sql2 = "SELECT `meta_value` as 'value' FROM `".$table."` WHERE `meta_key` = 'wpcf-keratty' AND `post_id` = '".$pid."';";
    $sql3 = "SELECT SUM(`price`) as 'value' FROM `".$kd_table."` WHERE `for` = '".$pid."';";

    $dons1 = $wpdb->get_results($sql2);
    $dons2 = $wpdb->get_results($sql3);

    foreach ($dons1 as $i2 => $val2) {
        $sum += $val2->value;
    }
    foreach ($dons2 as $i2 => $val3) {
        $sum += $val3->value;
    }   
}

return '<div class="groupDonations"><span style="color:#55A228!important;">This group has collected </span><br>'.$sum.'€</span></div>';
}

Answer 1

您需要使用WordPress number_format_i18n

$formatted = number_format_i18n( 1500.3, 2 ); // 1500.30

number_format也可以使用，但是它与语言无关

echo number_format(1500.3, 2, '.', ''); // 1500.30

Answer 2

$sum = 0; 
echo number_format($sum, 2, '.', '');

工作正常-实际显示它可能是前端问题？尝试将其用作字符串，

$sum = "" . number_format($sum, 2, '.', '');
