I have made the following file:
test.php
<?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');
?>
When I run from the command line (Ubuntu 12.x):
sudo php test.php
I get a file that shows up in my directory and works as intended. However now take the following file where I am trying to apply the above to a real world scenario - note: when I echo $htmlString I get a valid and expected string.
testPDF.php
<?php
// Start session and check if user is logged in
session_start();
if(!isset($_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');
?>
When I try to run the above by browsing to testPDF.php as a logged in user, I get nothing. No file is generated and no error/warning in the error logs. I've tried using $pdf->send() as well but no success.
My initial thought that this is a permissions issue, however I've tried setting testPDF.php to owner root and permission 755 but it still does not resolve the issue.
