Question

我使用下面的PHP代码在PHP搜索页面上显示以下文本，每页有6个结果。

显示x结果的x-x。

这样可行，但第一页显示：显示0-6而不是1-6的x结果，我在代码中更改此内容时遇到了问题。

如果没有找到结果，我还需要更改消息。即。显示0结果

 echo $paginate;  
  }
public function addPaginationInfo() {
$lastpage = ceil($this->total_pages/$this->limit);   
$LastPagem1 = $lastpage - 1;
$paginate = '<div><div style="color:#333">Showing<span style="color:#3E7CB3"> '.$this->limit_sql_start.'-'.$this->limit_sql_end.' </span>of <span style="color:#3E7CB3">'.$this->total_pages.'</span> Results</div></div>';
echo $paginate; 
}

这是完整的分页代码

public function executePagination(){

$db = DB::get_db();
$this->buildQuery();

$db->query(self::BASEQUERY,
  $this->fields_sql,
  $this->table_sql,
  $this->where_sql,
  $this->order_sql,
  $this->limit_sql);

$this->total_pages = $db->num_rows();
if(isset($_GET['page'])) {
$page = strip_tags(mysql_escape_string($_GET['page']));
} else { $page = FALSE; }    
if($page){
$start = ($page - 1) * $this->limit; 
} else {
$start = 0;  
}
$this->limit_sql_start = $start;
if($this->total_pages > $this->limit+$start) {
$this->limit_sql_end = $this->limit+$start; 
} else {
$this->limit_sql_end = $this->total_pages; 
}
$this->setLimit(" LIMIT $start, $this->limit "); 

$db->query(self::BASEQUERY,
  $this->fields_sql,
  $this->table_sql,
  $this->where_sql,
  $this->order_sql,
  $this->limit_sql);

  return $db->fetch_rows();
  }

更改此行

$paginate = '<div><div style="color:#333">Showing<span style="color:#3E7CB3"> '.$this->limit_sql_start.'-'.$this->limit_sql_end.' </span>of <span style="color:#3E7CB3">'.$this->total_pages.'</span> Results</div></div>';

要，

if($this->limit_sql_end > 0)
{
    $paginate = '<div><div style="color:#333">Showing<span style="color:#3E7CB3"> '.$this->limit_sql_start.'-'.($this->limit_sql_end + 1).' </span>of <span style="color:#3E7CB3">'.$this->total_pages.'</span> Results</div></div>';
}
else
    $paginate = '<div><div style="color:#333">Showing 0 Results</div></div>';
