Question

我正在设计一个woocommerce wordpress网站，其中杂志的广告空间正在出售。我被要求在每个产品中包含一个属性，说明开始日期，但隐藏当前月份加上月份以阻止人们购买空间并期望立即开始。

我已在此fiddle中提取HTML以用于示例目的。

＆＃13;

select {
  border-color: #F1F1F1;
  border-top-color: #DDD;
  border-left-color: #DDD;
  background-color: #F9F9F9;
  color: #515151;
  font: 12px Tahoma;
  padding: 8px;
  margin-bottom: 7px;
  -webkit-border-radius: 3px;
  -moz-border-radius: 3px;
  border-radius: 3px;
  webkit-transition: all 0.3s ease-in-out;
  -moz-transition: all 0.3s ease-in-out;
  -o-transition: all 0.3s ease-in-out;
  -ms-transition: all 0.3s ease-in-out;
  transition: all 0.3s ease-in-out;
}

在JS或PHP中执行此操作的最佳方法是什么？

Answer 1

您可以通过以下方式替换选项列表：

<option value="">Choose an option</option>
<?php
for ($m=1; $m<=12; $m++) {
    $currentMonth = date('n');
    $nextMonth = date('n') == 12 ? 1 : date('n') + 1;

    if ($m == $currentMonth || $m == $nextMonth) continue;

    $month = date('M', mktime(0,0,0,$m, 1, date('Y')));

    echo '<option value="'.$month.'" class="attached enabled">'.$month.'</option>';
}
?>

这提供了与您发布的相同的选项列表，减去当前和下个月。

PHP Sandbox

Answer 2

正如我所说，我是在PHP做的。您需要找出当前月份，并且不要在此列表或下个月的列表中添加option。你可以使用类似的东西：

<?php
    $months = array("Jan", "Feb", ..., "Dec");
    $thismonth = date('M');
    $date = date("Y-m-d");
    $date = strtotime(date("Y-m-d", strtotime($date)) . " +1 month");
    $nextmonth = date("M",$date);
    foreach ($months as $month) :
        if ($month != $thismonth && $month != $nextmonth):
            echo "<option value=\"" . $month . "\">" . $month . "</option>";
        endif;
    endforeach
?>
