Question

我已按照http://www.syahzul.com/cakephp/how-to-generate-pdf-in-cakephp-2-x-with-dompdf/上的说明操作并安装了DOMPDF版本0.6.1。当我在视图页面上按PDF按钮时，显示出乱码。（见下文）。我已经检查过这些字体是否安装在类库中。有什么建议吗？

第2步（在/app/Config/routes.php

    Router::parseExtensions('pdf');

第3步（在ChecksController.php中）

    class ChecksController extends AppController {

    public $components = array('Paginator', 'Session', 'RequestHandler');

第4步（在/app/View/Layouts/pdf/default.ctp中）

require_once(APP . 'Vendor' . DS . 'dompdf' . DS 
.dompdf_config.inc.php');
spl_autoload_register('DOMPDF_autoload');
$dompdf = new DOMPDF();
$dompdf->set_paper = 'A4';
$dompdf->load_html(utf8_decode($content_for_layout), Configure::read('App.encoding'));
$dompdf->render();
echo $dompdf->output();

第5步（在ChecksController.php中）

public function view_pdf($id = null) {
$this->Check->id = $id;
if (!$this->Check->exists()) {
    throw new NotFoundException(__('Invalid Check'));
}
// increase memory limit in PHP
ini_set('memory_limit', '512M');
$this->set('check', $this->Check->read(null, $id));

第6步（在check \ app \ View \ Checks \ pdf \ view_pdf.ctp中）

<div class="checks view">
<h2><?php echo __('Check Flight'); ?></h2>
<?php //echo debug($check); ?>
<dl>
    <dt><?php echo __('Instructor'); ?></dt>
    <dd>
        <?php echo h($check['Instructor']['first'] . ' ' . $check['Instructor']['last']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Pilot'); ?></dt>
    <dd>
        <?php echo h($check['Person']['first'] . ' ' .  $check['Person']['last']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Flight Date'); ?></dt>
    <dd>
        <?php echo h($check['Check']['flight_date']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Check Type'); ?></dt>
    <dd>
        <?php echo h($check['Check']['check_type']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Aircraft'); ?></dt>
    <dd>
        <?php echo h($check['Aircraft']['registration']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Hours'); ?></dt>
    <dd>    <?php echo h($check['Check']['hours']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Conditions'); ?></dt>
    <dd>
        <?php echo h($check['Check']['conditions']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Passed'); ?></dt>
    <dd>
        <?php echo h($check['Check']['passed']); ?>
        &nbsp;
    </dd>
    <dt><?php echo __('Notes'); ?></dt>
    <dd>
        <?php echo h($check['Check']['notes']); ?>
        &nbsp;
    </dd>
    <div class='items'>
        <dt><?php echo __('Additional Areas'); ?></dt>
        <dd>
            <?php foreach ($check['Assessment'] as $assessment): ?>
                    <?php  echo h($assessment['description']); ?><br/>
            <?php endforeach; ?>
        </dd>
     </div>   
</dl>

第7步（在app \ View \ Checks \ view.ctp中）

    <li><?php echo $this->Html->link(__('PDF'), array('action' => 'view_pdf', 'ext' => 'pdf', $check['Check']['id']));?></li>

输出：

Answer 1

它可能是这一行：

$dompdf->load_html(utf8_decode($content_for_layout), Configure::read('App.encoding'));

$ content_for_layout已弃用：请改用$this->fetch('content')。

DOMPDF产生胡言乱语
