【问题描述】：

我正在使用 Cakephp 2.x 尝试对我的模型索引之一进行分页。我已成功使用 Paginator 创建表格标题。我的标题能够毫无问题地对升序和降序进行排序。当我尝试在表格下方添加$this->Paginator->first、$this->Paginator->next、$this->Paginator->numbers 时，没有可见的分页器链接。我的数据库中现在有 6 个证据，我将分页器的限制设置为 3。这是我的代码：

EvidencesController.php

<?php
    class EvidencesController extends AppController{
        public $components = array('Session','Paginator');
        var $helpers = array( 'Form','Paginator' );

        public function index(){
            $this->Paginator->setting = array(
                'limit' => 3,
                'order' => array(
                    'Evidence.title' => 'asc'
                )
            );
            $data = $this->Paginator->paginate('Evidence');
            $this->set('evidences',$data);
        }
    }   
?>

index.ctp

<h1>Evidences</h1>
<?php echo $this->Html->link('Create a new Evidence', array('controller'=>'evidence','action'=>'add'))?>
<br>
<table>
    <tr>
        <th><?php echo $this->Paginator->sort('title'); ?></th>
        <th><?php echo $this->Paginator->sort('date'); ?></th>
        <th><?php echo $this->Paginator->sort('sourcetype'); ?></th>
        <th><?php echo $this->Paginator->sort('user_id'); ?></th>
        <th><?php echo $this->Paginator->sort('created'); ?></th>
        <?php if(AuthComponent::user('type') == 1) : ?>
        <th>Edit</th>
        <th>Delete</th>
        <?php endif; ?>
        <th>Add</th>
    </tr>
    <?php
        foreach($evidences as $evidence) :
    ?>
    <tr>
        <td><?php echo $this->Html->link($evidence['Evidence']['title'], array('controller' => 'evidences', 'action'=> 'view', $evidence['Evidence']['id'])); ?></td>
        <td><?php echo $evidence['Evidence']['date']; ?></td>
        <td><?php echo $evidence['Evidence']['sourcetype']; ?></td>
        <td><?php echo $evidence['User']['username']; ?></td>
        <td><?php echo $evidence['Evidence']['created']; ?></td>
    </tr>
    <?php
        endforeach;
        //unset($project);
    ?>
</table>
<?php 
    echo "<div class='paging'>";
    echo $this->Paginator->first("First");
    if($this->Paginator->hasPrev()){
        echo $this->Paginator->prev("Prev");
    }
    echo $this->Paginator->numbers(array('modulus' => 2));
    if($this->Paginator->hasNext()){
        echo $this->Paginator->next("Next");
    }
    echo $this->Paginator->last("Last");
    echo "</div>";
?>

如何使用 CakePHP 的 Paginator 添加第一个、最后一个、下一个、最后一个和数字计数？

任何帮助将不胜感激！

【解决方案1】：

通常我总是使用以下来自 cakePHP 网站的代码，并且它一直有效。

查看代码 ->

<?php
if($this->Paginator->counter('{:pages}') > 1) {
    //If disabled,then last para
    echo $this->Paginator->prev('&laquo;', array( 'tag' => 'li', 'escape' => false), null, array('class' => 'prev disabled prv' ,'tag' => 'li', 'escape' => false));
    echo $this->Paginator->numbers(array('separator' => '', 'tag' => 'li' ,'currentClass' => 'active', 'currentTag' => 'a' , 'escape' => false));
    echo $this->Paginator->next('&raquo;', array( 'tag' => 'li', 'escape' => false), null, array('class' => 'next disabled nxt' ,'tag' => 'li', 'escape' => false));
}
?>

控制器代码 ->

//Pagination logic
$this->paginate = array('conditions' => $conditions, 'limit' => PAGINATION_LIMIT, 'order' => 'CourseCategory.id DESC');
$getAllCategories = $this->paginate('CourseCategory');
if(isset($this->params['named']['page'])) //FOR RETAINING PAGINATION ON EDIT
    $this->Session->write('pagingUrl',$this->params['named']['page']);

$this->set('getAllCategories',$getAllCategories);
////Pagination logic

“查看”的扩展代码，如果您想了解更多信息 ->

            <?php 
                if($getAllCategories){
            ?>
        <table id="tablesorter-demo" class="tabelContent tablesorter" width="100%" border="0" cellspacing="0" cellpadding="0">
            <thead>

                <tr>
                    <th class="tabelHeading" width="33%" align="left">Title</td>
                    <th class="tabelHeading" width="33%" align="left">Status</td>
                    <th class="tabelHeading" width="33%" align="left">Actions</td>                                                          
                </tr>   
            </thead>


            <?php 
                $countCategories = 1;
                foreach($getAllCategories as $categorySingle)

                        $grayClass= 'class="lightGray"';
