在wordpress中带有变量的strtotime [英] strtotime with variable in wordpress

问题描述

我已尝试更改此代码:

function filter_where( $where = '' ) {
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-365 days')) . "'";
return $where;}
add_filter( 'posts_where', 'filter_where' );

进入这个:

function filter_where( $where = '' ) {
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-'.$timestamp.' days')) ."'";
return $where;}
add_filter( 'posts_where', 'filter_where' );

你可能注意到我试图将变量 $timestamp 放入 strtotime 中.但是代码不起作用.我是否按照正确的语法将变量放入 strtotime PHP 函数中?

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?

我感谢任何形式的帮助.

I appreciate any kind of help.

推荐答案

这是正确的代码 if $timestamp 包含一个正整数.

It is the correct code if $timestamp contains a positive integer.

然而，在没有global 关键字的函数上下文中，$timestamp 未定义且null.

However, in the context of that function and without the global keyword, $timestamp is undefined and null.

您的意思是将该变量作为 and_where() 的参数传递吗?

Do you mean to pass that variable as an argument of and_where()?
