我是一名学生网络程序员,并且遇到了我最近被分配的任务的问题。担任我职务的上一个人创建了一个有点小错误的新闻报道网站。
该网站的问题是,当您指定要显示新闻文章的日期范围时,日期将恢复为之前的状态,或者它们将随机更改为某些内容。尝试在2010年之前设置日期是每次都要发生此问题的唯一方法。有时它会在出现问题之前用于许多用途。
只是为了澄清,我不希望有人给我一个彻头彻尾的答案/为我做我的工作,特别是因为我真的想学习和提高我的技能。如果有人能指出我正确的方向来解决这个问题,我真的很感激。
以下是我正在查看的文件中对日期的所有引用:
// Create dates
$year = ( isset( $get['year'] ) ) ? $get['year'] : date("Y");
$year2 = ( isset( $get['year2'] ) ) ? $get['year2'] : date("Y");
$month = ( isset( $get['month'] ) ) ? $get['month'] : date("m");
$month2 = ( isset( $get['month2'] ) ) ? $get['month2'] : date("m");
$day = ( isset( $get['day'] ) ) ? $get['day'] : date("d");
$day2 = ( isset( $get['day2'] ) ) ? $get['day2'] : date("d");
//create first and second dates for range
$t_current = mktime(0, 0, 0, $month, $day, $year); // Current month Unix timestamp
$t_next = mktime(0, 0, 0, $month2, $day2+1, $year2); // date2 unix timestamp for date range
// Criteria
if ( $author_url) {
$this->EE->db -> where ( $author_name_field_id, $author_name);
$this->EE->db
-> where ("exp_channel_titles.entry_date >= $t_current")
-> where ("exp_channel_titles.entry_date <= $t_next");
}
else {
$this->EE->db
-> where ("exp_channel_titles.entry_date >= $t_current")
-> where ("exp_channel_titles.entry_date <= $t_next");
}

在代码的这一部分(注意第47行的for()
循环):
<select id="year" name="year" style="display:none">
<?php
//lists years
for ($i = 0; $i <= 3; ++$i) // Try to change this to: for ($i = 0; $i <= 5; ++$i)
{
$time = strtotime(sprintf('-%d years', $i));
$value = date('Y', $time);
$label = date('Y', $time);
//if year is set stay on that year
if($year==$value)
{ printf('<option value="%s" selected="selected">%s</option>' , $value, $label);
}
else
{printf('<option value="%s">%s</option>', $value, $label);}
}
本节(注意第106行的for()
循环):
<select id="year2" name="year2" style="display:none">
<?php
//lists years
for ($i = 0; $i <= 3; ++$i) // Try to change this to: for ($i = 0; $i <= 5; ++$i)
{
$time = strtotime(sprintf('-%d years', $i));
$value = date('Y', $time);
$label = date('Y', $time);
//if year is set stay on that year
if($year2==$value)
{ printf('<option value="%s" selected="selected">%s</option>' , $value, $label);
}
else
{printf('<option value="%s">%s</option>', $value, $label);}
}
//first year selected instead of blank
?>
正在创建一个下拉选择,从当前年份到三年前一年。因此,当您指定年份之外(2010年之前)时,年份不是<select>
框的一部分。同样适用于<select>
的{{1}}。
如果您想支持更多年,只需将3的值更改为其他内容。
顺便说一句,尝试添加检查开始日期&lt; =结束日期。我试过了,虽然它没有给我任何错误,但它只显示没有结果,而不是说它是无效的日期范围。

此时在代码中:
//create first and second dates for range
$t_current = mktime(0, 0, 0, $month, $day, $year); // Current month Unix timestamp
$t_next = mktime(0, 0, 0, $month2, $day2+1, $year2); // date2 unix timestamp for date range
我肯定会添加一个检查以确保$ t_next晚于$ t_current,因为这将是我要查找的第一个逻辑问题。
if($t_current>$t_next){
// swap them over
$tmp=$t_current;
$t_current=$t_next;
$t_next=$tmp;
}
