我制作了以下文件:
test.php的
<?php
require 'vendor/autoload.php';
use mikehaertl\wkhtmlto\Pdf;
$htmlString = <<<EOT
<!DOCTYPE html>
test
</html>
EOT;
$pdf = new Pdf($htmlString);
$pdf->setOptions(array(
'orientation' => 'landscape'
));
$pdf->saveAs('new.pdf');
?>
当我从命令行(Ubuntu 12.x)运行时:
sudo php test.php
我收到一个显示在我的目录中并按预期工作的文件。但是现在采取以下文件,我试图将上述内容应用于现实世界的场景 - 注意:当我回显$ htmlString时,我得到一个有效且预期的字符串。
testPDF.php
<?php
// Start session and check if user is logged in
session_start();
if(!isset($_SESSION['permission']))
{
die('Please login.');
}
// Dependencies
require 'vendor/autoload.php';
use mikehaertl\wkhtmlto\Pdf;
require 'database.php';
// Initialize
$client = $db->real_escape_string($_GET['client']);
$start_date = $db->real_escape_string($_GET['start_date']);
$end_date = $db->real_escape_string($_GET['end_date']);
$jobs = array();
$htmlString = '';
// Get list of jobs from DB & save to array
$query = "SELECT somecolumns FROM mydatabase WHERE start_date > '{$start_date}' AND end_date < '{$end_date}' AND client = '{$client}'";
if(!$result = $db->query($query))
{
die('There was an error running the query [' . $db->error . ']');
}
while($r = mysqli_fetch_assoc($result))
{
$jobs[] = $r;
}
// Loop through jobs array and formulate HTML string
foreach($jobs as $value)
{
$id = $value['id'];
$name = $value['name'];
$tech = $value['tech'];
$time_closed = $value['time_closed'];
$time_total = $value['time_total'];
$time_charged = $value['time_charged'];
$description = $value['description'];
$htmlString = $htmlString . <<<EOT
<h4 style="text-align: center;">{$id} - {$name}</h5>
<table id="simple-table" class="table table-striped table-bordered table-hover">
<thead>
<tr>
<th style="width: 180px;">Date</th>
<th>Description</th>
<th style="width: 50px;">Duration</th>
<th style="width: 150px;">Time Charged</th>
<th style="width: 150px;">Technician</th>
</tr>
</thead>
<tbody id="jobs_start">
<tr>
<td>{$time_closed}</td>
<td>{$description}</td>
<td>{$time_total}</td>
<td>{$time_charged}</td>
<td>{$tech}</td>
</tr>
</tbody>
</table>
EOT;
}
$pdf = new Pdf($htmlString);
$pdf->setOptions(array(
'orientation' => 'landscape'
));
$pdf->saveAs('new.pdf');
?>
当我尝试通过浏览testPDF.php作为登录用户来运行上述操作时,我什么都没得到。错误日志中没有生成文件且没有错误/警告。我尝试过使用$ pdf-&gt; send(),但没有成功。
我最初认为这是权限问题,但是我已经尝试将testPDF.php设置为所有者root和权限755,但它仍然无法解决问题。
答案 0 :(得分:0)
问题在于,当向pdf对象发送HTML字符串时,它会查找标记以确定它是否为html。
第一个示例有一个HTML标记,而第二个文件没有任何html标记,因此无声地失败。
