为了有一个像这样的数组输出
array(2) { ["2012-08-16"]=> array(1) { [0]=> array(2) { ["title"]=> string(24) "RLI Class #42 Graduation" ["event_date"]=> string(10) "2012-08-16" } } ["2012-08-24"]=> array(1) { [0]=> array(2) { ["title"]=> string(10) "Test Event" ["event_date"]=> string(10) "2012-08-24" } } }
我正在尝试以下
$array = array('title' => $mytitle, 'event_date' => $myyear."-".$mymonth."-".$myday);
$events[$array['event_date']] = $array['title'];
但是我得到的输出是
array(1) { [""]=> NULL } array(1) { ["2012-8-24"]=> string(10) "Test Event" } array(1) { ["2012-8-16"]=> string(25) "RLI Class #42 Graduation" }
我应该如何更改代码以让 $events 以所需的数组格式输出?
编辑 以防万一代码的一些背景将有助于找到解决方案,这里是
while ( $query->have_posts() ) : $query->the_post();
$mytime = get_post_meta($post->ID, 'wpcf-start-date', true); // this has 2 entries: 1>1347408000 and 2>1347408000
$mydate = date("Y-m-D",$mytime);
$mydatearr = getdate($mytime);
$myday = $mydatearr['mday']; // returns values 16 and 24
$mymonth = $mydatearr['mon']; // returns values 8 and 8
$myyear = $mydatearr['year']; // returns values 2012 and 2012
$mytitle = $post->post_title;
if (($myyear == $year) && ($mymonth == $month)) //The $year is declared earlier as 2012 and $month as 8
接下来是我替换为的代码
$events = array(); ## Declare the new array.
foreach ($array as $line) {
$event_date = $line['event_date']; ## Set event_date to a variable
$events[$event_date] = array( 'title' => $line['title'], 'event_date' => $event_date ); ###add new value to new array with key value }
var_dump($events);
而最后
endwhile;
编辑 好。我似乎错误地删除了我的 $array 声明,并早先在循环内声明了 $events 数组。所以我正在更新新代码
$events = array(); ## Declare the new array.
while ( $query->have_posts() ) : $query->the_post();
$mytime = get_post_meta($post->ID, 'wpcf-start-date', true);
$mydate = date("Y-m-D",$mytime);
$mydatearr = getdate($mytime);
$myday = $mydatearr['mday'];
$mymonth = $mydatearr['mon'];
$myyear = $mydatearr['year'];
$mytitle = $post->post_title;
if (($myyear == $year) && ($mymonth == $month))
$array = array('title' => $mytitle, 'event_date' => $myyear."-".$mymonth."-".$myday);
foreach ($array as $line) {
$event_date = $line['event_date']; ## Set event_date to a variable
$events[$event_date] = array( 'title' => $line['title'], 'event_date' => $event_date ); ###add new value to new array with key value
}
var_dump($events);
endwhile;
$array 的 var_dump 给出
NULL
