摘要：zentaoPHP提供的分頁解決方案。

本篇目錄

分頁對于基于數據庫的應用來講，是很常見的一個問題。新的zentaoPHP框架中，提供了內置的分頁功能。使用如下：

我們以查詢用戶列表爲例，在應用中建立一個user的模塊，在其中的control文件中，定義一個browse方法，來完成分頁的功能：

一、browse方法關于分頁的三個參數

browse方法需要定义三个参数：recTotal, recPerPage, pageID，变量名是固定的。

public function browse($recTotal, $recPerPage, $pageID)
{
    /* 加载分页类，并生成pager对象。*/
    $this->app->loadClass('pager', $static = true);
    $pager = new pager($recTotal, $recPerPage, $pageID);
    /* 将分页类传给model，进行分页。*/
    $users = $this->user->getList($pager);
}

二、model方法中調用pager對象

model中定義一個getList方法，接收pager對象，並在dao查詢的時候，調用pager($pager)方法來生成分頁語句。

public function getList($pager)
{
    return $this->dao->select(*)->from('user')->page($pager)->fetchAll();
}

三、control中將pager對象賦值給模板

再回到control的browse方法中，將pager對象賦值給模板。

public function browse($recTotal, $recPerPage, $pageID)
{
    /* 加载分页类，并生成pager对象。*/
    $this->app->loadClass('pager', $static = true);
    $pager = new pager($recTotal, $recPerPage, $pageID);
    /* 将分页类传给model，进行分页。*/
    $users = $this->user->getList($pager);
    
    /* 赋值到模板。*/
    $this->view->users = $users;
    $this->view->pager = $pager;
}

模板中显示分页链接：show()方法有两个参数，$align: left, center, right，默认是居右对齐。$type: full|short|shortest

<?php $pager->show();?>

For the next few days the proposed journey was the theme of conversation in the Bassett family. Mary examined all the books she could find about the countries her brother expected to visit; then she made a list of the things she desired, and the day before his departure she gave him a sealed envelope containing the paper. She explained that he was not to open it until he reached Japan, and that he would find two lists of what she wanted. From the railway station our travellers went to the Nihon Bashi, in order to begin their journey from the centre of the empire. A more[Pg 116] practical reason was a desire to see the river, and the great street leading to it, as they would get a good idea of the extent of the city by taking this route, and would obtain numerous glimpses of Japanese street life. They found the streets full of people, and it seemed to the boys that the whole population must be out for an airing. But the Doctor informed them that the sight they were witnessing was an every-day affair, as the Japanese were essentially an outdoor people, and that many of the industries which in other countries would be conducted under a roof were here seen in progress out of doors. The fronts of the Japanese houses are quite open to the view of the public, and there is hardly anything of what we call privacy. It was formerly no uncommon sight to see people bathing in tubs placed in front of their door-steps; and even at the present time one has only to go into the villages, or away from the usual haunts of foreigners, to see that spectacle which would be unknown in the United States. The bath-houses are now closed in front in all the cities, but remain pretty much as before in the smaller towns. Year by year the country is adopting Western ideas, and coming to understand the Western views of propriety. The one at the end accomplishing a graceful pirouette is me--I mean Even M. Vacherot, with all his anxiety to discover an Oriental origin for Neo-Platonism, cannot help seeing that this attack on the Gnostics was inspired by an indignant reaction of Greek philosophy against the inroads of Oriental superstition, and that the same character belongs more or less to the whole system of its author. But, so far as we are aware, Kirchner is the only critic who has fully worked out this idea, and exhibited the philosophy of Plotinus in its true character as a part of the great classical revival, which after producing the literature of the second century reached its consummation in a return to the idealism of Plato and Aristotle.522 "At eight o'clock, sir," he answered resentfully, "in front of the dry-goods store on the main street. If that is convenient for your men." "Come on over," the master said from the doorway. "Come on over." He made a beckoning motion. She could not discipline her attitude towards him—sometimes she was composed, distant even in her thoughts; at others a kind of delirious excitement possessed her, she flushed and held down her head in his presence, could not speak to him, and groped blindly for escape. She would, on these occasions, end by returning to Rye, but away from Reuben a restless misery tormented her, driving her back to Odiam. "My lord, I was unwilling that a soul should be lost——" This unexpected consummation wrought upon Holgrave so much, that, with the sullen determination which had marked his character on previous occasions, he resolved not to answer any questions whatever. We should have premised, that the galleyman had given Holgrave a solemn promise, that if any ill befel him, Margaret should be cared for like his own wife. This was a solace to him, as he thought over his mother's death, and his own evil destiny. But there was another solace, that, strange as it may appear to some minds, arose from the thought, that whatever might befall him, the baron's heir would share in it. At first, when he had been removed to Sudley, mild measures were resorted to. He was lodged in a comfortable apartment, fed plentifully, and promised his freedom with whatever reward he might claim, if he would but speak satisfactorily as to the lost child. When this failed, he was sent to the keep, and for a week black bread and cold water were the only articles of aliment supplied; and then the peine forte et dure was resorted to. But though his face was swollen, and of a livid, purple hue, and the eyes seemed starting from their sockets at the pressure on his chest, as he lay with his limbs extended on the earth, yet would he not speak the word which would have released him from all this suffering. The extreme punishment, however, of adding weights until nature could sustain no more, was delayed from day to day. The baroness had twice given birth to children who had survived but a few hours; the third had lived, but it was a daughter; and as she dwelt upon the approaching extinction of their noble line, she dared not permit the order to be given that might deprive her of all hope. Day after day were the weights pressing and stifling, and forcing the blood that still crept through his veins to his extremities, and distending the hands and feet with a feeling of agony. But though the pressure was at each time removed when the leech pronounced the prisoner exhausted, yet it appeared repetition, though slow, would effect the work as surely as if the punishment had been in the first instance applied in all its legal rigour.
