Question

我的Wordpress网站上有一个PHP脚本，我希望在其中显示我所有注册俱乐部会员的10周年纪念日。如果今年没有周年纪念日，则会显示一条消息，上面写着“今年没有纪念日”。到目前为止我做了什么：

<?php
$args2 = array(
'role' => '',
'meta_key' => 'last_name',
'orderby'  => 'meta_value',
'order' => 'ASC'
);

$members = get_users($args2);

echo '<table cellpadding="0" cellspacing="0" style="margin-top:20px;">';
foreach ($members as $user) {

$clubeintritt = new DateTime($user->club); // club entry date
$jahre = $clubeintritt->diff(new DateTime); // no. of years in the club
$jubi=('10'); // 10 years

if($jahre->y == $jubi) {

echo '<tr>';
echo '<td>' . $user->first_name . ' ' .$user->last_name .'</td>';
echo '</tr>';
}
}

if($jahre->y != $jubi) {
echo 'No Aniversary this yeaar';
}
echo '</table>';
?>

现在，我获得了10年俱乐部成员的名单，但也传达了今年没有周年纪念日的信息。

我想必须有“endforeach”的东西，但无法找到解决方案。

非常感谢任何帮助。非常感谢

Answer 1

您必须将布尔值设置为＆＃34; false＆＃34;在你的循环之前，意思是＆＃34;没有找到周年纪念日＆＃34;。如果您找到，请将其设置为＆＃34; true＆＃34;：

echo '<table cellpadding="0" cellspacing="0" style="margin-top:20px;">';
$found = false;
foreach ($members as $user) {

    $clubeintritt = new DateTime($user->club); // club entry date
    $jahre = $clubeintritt->diff(new DateTime); // no. of years in the club
    $jubi=('10'); // 10 years

    if($jahre->y == $jubi) {
        $found = true;
        echo '<tr>';
        echo '<td>' . $user->first_name . ' ' .$user->last_name .'</td>';
        echo '</tr>';
    }
}

if(!$found) {
    echo 'No Aniversary this yeaar';
}
echo '</table>';

使用计数器很简单：

<?php
$args2 = array(
'role' => '',
'meta_key' => 'last_name',
'orderby'  => 'meta_value',
'order' => 'ASC'
);

$members = get_users($args2);
$aCounter=0;

echo '<table cellpadding="0" cellspacing="0" style="margin-top:20px;">';
foreach ($members as $user) {

    $clubeintritt = new DateTime($user->club); // club entry date
    $jahre = $clubeintritt->diff(new DateTime); // no. of years in the club
    $jubi=('10'); // 10 years

    if($jahre->y == $jubi) {
    $aCounter++;
    echo '<tr>';
    echo '<td>' . $user->first_name . ' ' .$user->last_name .'</td>';
    echo '</tr>';
    }
}

if($aCounter === 0) {
echo 'No Aniversary this yeaar';
}

echo '</table>';
?>

Answer 3

更改：

echo '<table cellpadding="0" cellspacing="0" style="margin-top:20px;">';
foreach ($members as $user) {

$clubeintritt = new DateTime($user->club); // club entry date
$jahre = $clubeintritt->diff(new DateTime); // no. of years in the club
$jubi=('10'); // 10 years

if($jahre->y == $jubi) {

echo '<tr>';
echo '<td>' . $user->first_name . ' ' .$user->last_name .'</td>';
echo '</tr>';
}
}

if($jahre->y != $jubi) {
echo 'No Aniversary this yeaar';
}
echo '</table>';

到

$out = '';

foreach ($members as $user) {

$clubeintritt = new DateTime($user->club); // club entry date
$jahre = $clubeintritt->diff(new DateTime); // no. of years in the club
$jubi=('10'); // 10 years

if($jahre->y == $jubi) {

$out .= '<tr>';
$out .= '<td>' . $user->first_name . ' ' .$user->last_name .'</td>';
$out .= '</tr>';
}
}

if(empty($out)) {
echo 'No Aniversary this yeaar';
}
else
{   echo '<table cellpadding="0" cellspacing="0" style="margin-top:20px;">';
echo $out;
echo '</table>';

}

Answer 4

检查ws.Range("H3:M7).Copy() ws.Range("H3").Insert(Shift="xlShiftDown")的最后一个值。它不等于$jahre->y。因此，for循环的最后一次迭代会导致问题。

Answer 5

更改以下行：

$members = get_users($args2);
$aniversary = false;
echo '<table cellpadding="0" cellspacing="0" style="margin-top:20px;">';
foreach ($members as $user) {

$clubeintritt = new DateTime($user->club); // club entry date
$jahre = $clubeintritt->diff(new DateTime); // no. of years in the club
$jubi=('10'); // 10 years

if($jahre->y == $jubi) {

echo '<tr>';
echo '<td>' . $user->first_name . ' ' .$user->last_name .'</td>';
echo '</tr>';
$aniversary = true;
}
}

if(!$aniversary) {
echo 'No Aniversary this yeaar';
}
echo '</table>';
?>

PHP foreach if / else with table
