Question

我收到了这段代码：

/**
 * Transforms field value to readable text for listing.
 *
 * @param string $fieldName
 * @param Entity_Topic $entity
 * @return string
 */
public function presenter($fieldName, *** $entity) {
  $years = range(2014, 2020);
    if ('dateFrom' == $fieldName) {
      foreach($years as $year) {
        $list = array(
            $year.'-01-01' => 'Leden '.$year,
            $year.'-02-01' => 'Únor '.$year,
            $year.'-03-01' => 'Březen '.$year,
            $year.'-04-01' => 'Duben '.$year,
            $year.'-05-01' => 'Květen '.$year,
            $year.'-06-01' => 'Červen '.$year,
            $year.'-07-01' => 'Červenec '.$year,
            $year.'-08-01' => 'Srpen '.$year,
            $year.'-09-01' => 'Září '.$year,
            $year.'-10-01' => 'Říjen '.$year,
            $year.'-11-01' => 'Listopad '.$year,
            $year.'-12-01' => 'Prosinec '.$year,
        );
        return $list[$entity->getDateFrom()];
      }
    }
    return '';
}

此代码仅显示2014年的数据，其他年份仅为空。任何想法如何让它正常工作，以便它可以显示其他年份？

if ('dateFrom' == $fieldName) {
          foreach($years as $year) {
            $list = array(
                   ***
            );
          }
  return $list[$entity->getDateFrom()];
}

这不起作用..

您已解决了一个问题但仍有一个问题。您在$list循环的每次迭代中覆盖foreach。即使你做$list[] = array(...，问题也不会消失，因为你的最终目的是从这个数组中获取适当的数据。因此，请按以下方式更改presenter()方法，

public function presenter($fieldName, $entity) {
    $years = range(2014, 2020);
    if ('dateFrom' == $fieldName) {
        $years = range(2014, 2020);
        $months = array('Leden', 'Únor', 'Březen', 'Duben', 'Květen', 'Červen', 'Červenec', 'Srpen', 'Září', 'Říjen', 'Listopad', 'Prosinec');
        $list = array();
        foreach($years as $year){
            for($i = 1; $i <= 12; ++$i){
                $list[$year . '-' . $i . '-01'] = $months[$i - 1] . ' ' . $year;
            }
        }
        return $list[$entity->getDateFrom()];
    }
    return '';
}

每年范围适用于阵列
