我想让文章循环div 填充在 while 循环的 echo 函数中。我正在尝试创建一个动态分页，该分页每页动态打印文章循环div。这非常简单，例如，当用户更改页面时，我希望接下来的几个div显示在该页面上，依此类推。
<?php
class Pagination {
public $current_page;
public $per_page;
public $total_count;
public function __construct($page=1, $per_page=20, $total_count=0) {
$this->current_page = (int)$page;
$this->per_page = (int)$per_page;
$this->total_count = (int)$total_count;
}
public function offset() {
return ($this->current_page - 1) * $this->per_page;
}
public function total_pages() {
return ceil($this->total_count/$this->per_page);
}
public function previous_page() {
return $this->current_page - 1;
}
public function next_page() {
return $this->current_page + 1;
}
public function has_previous_page() {
return $this->previous_page() >= 1 ? true : false;
}
public function has_next_page() {
return $this->next_page() <= $this->total_pages() ? true : false;
}
}
$page = !empty($_GET['page']) ? (int)$_GET['page'] : 1;
$per_page = 2;
$total_count = 10;
$pagination = new Pagination($page, $per_page, $total_count);
?>

$limit = $pagination->per_page;
while($i<=$pagination->total_count && $limit>0) {
echo '**IN HERE POPULATE THE ARTICLE-LOOP DIVS**';
$i++;
$limit--;
}
?>
</div>
<ul>
<?php
if($pagination->has_previous_page()) {
echo '<li style="display:inline"><a href="index.php?page='.$pagination->previous_page().'">«</a></li>';
} else {
echo '<li style="display:inline" class="disabled"><a href="#">«</a></li>';
}
?>
<?php
for($i=1; $i<=$pagination->total_pages(); $i++) {
echo '<a href="index.php?page='.$i.'"><li style="display:inline; margin-left:5px; margin-right:5px">'.$i.'</li></a>';
}
?>
<?php
if($pagination->has_next_page()) {
echo '<li style="display:inline"><a href="index.php?page='.$pagination->next_page().'">»</a></li>';
} else {
echo '<li style="display:inline" class="disabled"><a href="#">»</a></li>';
}
?>
</ul>
</body>
</html>
而不是
<?php
$i = $pagination->offset() + 1;
$limit = $pagination->per_page;
while($i<=$pagination->total_count && $limit>0) {
echo '**IN HERE POPULATE THE ARTICLE-LOOP DIVS**';
$i++;
$limit--;
}
?>
你可以使用类似的东西
<?php
$i = $pagination->offset() + 1;
$limit = $pagination->per_page;
while($i<=$pagination->total_count && $limit>0) {
?>
**IN HERE POPULATE THE ARTICLE-LOOP DIVS** // html content
<?php
$i++;
$limit--;
}
?>
你应该使用第二个。很多时候第一个不能正常工作。
