wordpress 中带有变量的 strtotime
我尝试将
function filter_where( $where = '' ) {
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-365 days')) . "'";
return $where;}
add_filter( 'posts_where', 'filter_where' );
以下代码更改为：
function filter_where( $where = '' ) {
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-'.$timestamp.' days')) ."'";
return $where;}
add_filter( 'posts_where', 'filter_where' );
您可能会注意到我尝试将变量 $timestamp 放入 strtotime 中。但是该代码不起作用。我是否使用了正确的语法将变量放入 strtotime PHP 函数中？
我很感激任何形式的帮助。
I've tried to change this code:
function filter_where( $where = '' ) {
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-365 days')) . "'";
return $where;}
add_filter( 'posts_where', 'filter_where' );
into this one:
function filter_where( $where = '' ) {
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-'.$timestamp.' days')) ."'";
return $where;}
add_filter( 'posts_where', 'filter_where' );
You may noticed that I've tried to put variable $timestamp inside strtotime. However the code doesn't work. Did I do the correct syntax to put the variable within the strtotime PHP function?
I appreciate any kind of help.

如果
$timestamp包含正整数，则它是正确的代码。但是，在该函数的上下文中并且没有
global关键字，$timestamp未定义且null。您的意思是将该变量作为
and_where()的参数传递吗？It is the correct code if
$timestampcontains a positive integer.However, in the context of that function and without the
globalkeyword,$timestampis undefined andnull.Do you mean to pass that variable as an argument of
and_where()?
