[英]Error in entries per page count
I'm working on a site which has paginated entries and want to output where you are currently, eg Showing 10-18 of 50 results
but am having trouble getting the correct output if there are less entries than the per-page limit. 我正在一个有分页条目并希望输出当前位置的网站,例如,
Showing 10-18 of 50 results
但是如果条目数少于每页限制,则很难获得正确的输出。
The site uses ExpressionEngine where the last segment of the URI indicates where you are in the page list, so if the limit is 9 per page, the URI would be /path/to/page/P9/
when you're on the second page, P18
page 3 etc. 该站点使用ExpressionEngine,其中URI的最后一段指示您在页面列表中的位置,因此,如果限制为每页9,则当您位于第二页时,URI将为
/path/to/page/P9/
, P18
第3页等。
This is what I have so far: 这是我到目前为止的内容:
$output = '';
// the variables below are passed from a template to a plugin which does the processing
$url_segment = $this->EE->TMPL->fetch_param('url_segment'); // e.g. P9, P18 etc.
$per_page = $this->EE->TMPL->fetch_param('page_num'); // e.g. 9
$total_entries = $this->EE->TMPL->fetch_param('total'); // e.g. 50
$current_page = preg_match('/^P+[0-9]+$/', $url_segment) === 1 ? str_replace('P','', $url_segment) +1 : 1;
if ($total_entries == 1) {
$output .= '1 tour';
} else {
if ($total_entries <= $per_page){
$output .= '1 to '.($per_page<=$total_entries ? $total_entries : $per_page);
} else {
$output .= $current_page.' to ';
$output .= $current_page+$per_page-1;
}
$output .= ' of '.$total_entries.' tours';
}
return $this->return_data = $output;
if ($total_entries <= $per_page)
doesn't ever seem to evaluate to true, eg if page limit is 9 but only three entries, it'll say 1 to 9 of 3 entries
. if ($total_entries <= $per_page)
似乎从未评估为true,例如,如果页面限制为9,但只有三个条目,它将说1 to 9 of 3 entries
。
I thought it might be because I need to make the variables integers but doing that means the other side of the conditional always evaluates as true so when there are more entries that the per-page limit, the output is always same regardless of which page you're on, eg 1 to 14 of 14 entries
on all pages. 我认为这可能是因为我需要使变量为整数,但这意味着条件的另一端始终求值为true,因此,当有更多条目超出每页限制时,无论您在哪一页上输出,输出始终是相同的例如在所有页面上
1 to 14 of 14 entries
。
Where am I going wrong? 我要去哪里错了?
if ($total_entries <= $per_page){
$output .= '1 to '.($per_page<=$total_entries ? $total_entries : $per_page);
On this part, you first check if $total_entries
is less or equal than $per_page
, but just after, you check if it's more or equal. 在这一部分,您首先要检查
$total_entries
是否小于或等于$per_page
,但是$per_page
,您要检查它是否大于或等于$per_page
。 Bad logic here (and your second if statement is reversed). 这里的逻辑不好(第二个if语句相反)。
Try this : 尝试这个 :
if ($total_entries <= $per_page){
$output .= '1 to '.$total_entries;
