我有一个数组分页类。但该类显示所有页码。
我的意思是如果我有100页,它会显示所有100页的页码。
有人可以帮助我在这个分页课程中实现中档数字
<?php
class pagination
{
/**
* Properties array

* @access private

private $_properties = array();
/**

'page' => 1,
'perPage' => 10
);
/**

public function __construct($array, $curPage = null, $perPage = null)
{
$this->array = $array;

}
// Take the length of the array
$this->length = count($this->array);
// Get the number of pages
$this->pages = ceil($this->length / $this->perPage);
// Calculate the starting point
$this->start = ceil(($this->page - 1) * $this->perPage);
// return the portion of results
return array_slice($this->array, $this->start, $this->perPage);
}
/**

public function getLinks($params = array())
{
// Initiate the links array
$plinks = array();
$links = array();
$slinks = array();
// Concatenate the get variables to add to the page numbering string
$queryUrl = '';
if (!empty($params) === true) {
unset($params['page']);
$queryUrl = '&'.http_build_query($params);
}
// If we have more then one pages
if (($this->pages) > 1) {
// Assign the 'previous page' link into the array if we are not on the first page
if ($this->page != 1) {
if ($this->_showFirstAndLast) {
$plinks[] = ' <a href="?page=1'.$queryUrl.'">«« First </a> ';
}
$plinks[] = ' <a href="?page='.($this->page - 1).$queryUrl.'">« Prev</a> ';
}
// Assign all the page numbers & links to the array
for ($j = 1; $j < ($this->pages + 1); $j++) {
if ($this->page == $j) {
$links[] = ' <a class="selected">'.$j.'</a> '; // If we are on the same page as the current item
} else {
$links[] = ' <a href="?page='.$j.$queryUrl.'">'.$j.'</a> '; // add the link to the array
}
}
// Assign the 'next page' if we are not on the last page
if ($this->page < $this->pages) {
$slinks[] = ' <a href="?page='.($this->page + 1).$queryUrl.'"> Next » </a> ';
if ($this->_showFirstAndLast) {
$slinks[] = ' <a href="?page='.($this->pages).$queryUrl.'"> Last »» </a> ';
}
}
// Push the array into a string using any some glue
return implode(' ', $plinks).implode($this->mainSeperator, $links).implode(' ', $slinks);
}
return;
}
}
以下是我如何使用
$contacts = array();
if(count($contacts))
{
$pagination = new pagination($contacts, (isset($_GET['page']) ? $_GET['page'] : 1), 50);
$ContactPages = $pagination->getResults();
if (count($ContactPages) != 0) {
echo $pageNumbers = $pagination->getLinks();
}
}

首先,您应该在课程负责人中声明您的班级成员,例如$start
,$pages
等,而不是按需声明他们。这将提高可读性和代码质量,并有助于避免错误。
要修复您的类,请将getLinks()
中的for循环及其周围的代码更改为:
// Assign the 'previous page' link into the array if we are not on the first page
if ($this->page != 1) {
if ($this->_showFirstAndLast) {
$plinks[] = ' <a href="?page=1'.$queryUrl.'">«« First </a> ';
}
$plinks[] = ' <a href="?page='.($this->start).$queryUrl.'">« Prev</a> ';
}
// Assign all the page numbers & links to the array
for ($j = $this->start + 1; $j < ($this->start + $this->pages + 1); $j++) {
if ($this->page == $j) {
$links[] = ' <a class="selected">'.$j.'</a> '; // If we are on the same page as the current item
} else {
$links[] = ' <a href="?page='.$j.$queryUrl.'">'.$j.'</a> '; // add the link to the array
}
}
// Assign the 'next page' if we are not on the last page
if ($this->page < $this->pages) {
$slinks[] = ' <a href="?page='.($this->start + $this->page + 2).$queryUrl.'"> Next » </a> ';
if ($this->_showFirstAndLast) {
$slinks[] = ' <a href="?page='.($this->pages).$queryUrl.'"> Last »» </a> ';
}
}
你没想过这个 - >开始记住。
我已经对它进行了基本的测试,但它确实有效。
