2. Enable it in your config/application.config.php like the step 4 in the previous section.

Usage

Render to browser

The following example demonstrates a typical usage of the LosPdf module inside an Action in a Controller:

    public function pdfAction()
    {
        $generated = new \DateTime('now');
        $genetared = $gerado->format('d/m/Y H:i:s');

        $pdf = new PdfModel();
        $renderer = $this->getServiceLocator()->get('ViewPdfRenderer');
        $renderer->getEngine()->setHTMLHeader('<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-bottom: 1px solid #000"><tr>
<td width="33%"><span style="font-weight: bold; font-style: italic;">Client</span></td>
<td width="33%" align="center" style="font-weight: bold; font-style: italic;">Report Name</td>
<td width="33%" style="text-align: right; ">My Company</td>
</tr></table>
');
        $renderer->getEngine()->setHTMLFooter('Footer', '<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-top: 1px solid #000"><tr>
<td width="50%" style="text-align: left; font-weight: bold; font-style: italic;">Generated: '.$generated.'</td>
<td width="50%" style="text-align: right; ">Page {PAGENO}</td>
</tr></table>
');

        $pdf->setTerminal(true);
        $pdf->setVariables(['name'=>'Leandro']);
        $pdf->setOption("paperSize", "a4");

        return $pdf;
    }

And use the view file as usual.

You can set any mPdf option through $renderer->getEngine():

$renderer = $this->getServiceLocator()->get('ViewPdfRenderer');
$renderer->getEngine()->pagenumPrefix = 'Page n ';

Render to string

You can capture the pdf output to a string:

    public function pdfAction()
    {
        $generated = new \DateTime('now');
        $genetared = $gerado->format('d/m/Y H:i:s');

        $pdf = new PdfModel();
        $renderer = $this->getServiceLocator()->get('ViewPdfRenderer');
        $renderer->getEngine()->setHTMLHeader('<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-bottom: 1px solid #000"><tr>
<td width="33%"><span style="font-weight: bold; font-style: italic;">Client</span></td>
<td width="33%" align="center" style="font-weight: bold; font-style: italic;">Report Name</td>
<td width="33%" style="text-align: right; ">My Company</td>
</tr></table>
');
        $renderer->getEngine()->setHTMLFooter('Footer', '<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-top: 1px solid #000"><tr>
<td width="50%" style="text-align: left; font-weight: bold; font-style: italic;">Generated: '.$generated.'</td>
<td width="50%" style="text-align: right; ">Page {PAGENO}</td>
</tr></table>
');

        $pdf->setTerminal(true);
        $pdf->setVariables(['name'=>'Leandro']);
        $pdf->setOption("paperSize", "a4");
        $pdf->setTemplate('site/index/pdf');
        $output = $renderer->renderToString($pdf);
        
        //Do something with output
    }

Render to file

You can save the pdf to a file:

    public function pdfAction()
    {
        $generated = new \DateTime('now');
        $genetared = $gerado->format('d/m/Y H:i:s');

        $pdf = new PdfModel();
        $renderer = $this->getServiceLocator()->get('ViewPdfRenderer');
        $renderer->getEngine()->setHTMLHeader('<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-bottom: 1px solid #000"><tr>
<td width="33%"><span style="font-weight: bold; font-style: italic;">Client</span></td>
<td width="33%" align="center" style="font-weight: bold; font-style: italic;">Report Name</td>
<td width="33%" style="text-align: right; ">My Company</td>
</tr></table>
');
        $renderer->getEngine()->setHTMLFooter('Footer', '<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-top: 1px solid #000"><tr>
<td width="50%" style="text-align: left; font-weight: bold; font-style: italic;">Generated: '.$generated.'</td>
<td width="50%" style="text-align: right; ">Page {PAGENO}</td>
</tr></table>
');

        $pdf->setTerminal(true);
        $pdf->setVariables(['name'=>'Leandro']);
        $pdf->setOption("paperSize", "a4");
        $pdf->setTemplate('site/index/pdf');
        $renderer->renderToFile($pdf, '/tmp/report.pdf');
    }

Mixing outputs

You can use more than one render type. the following example will save the pdf to a file, render the pdf to a string and to the browser:

    public function pdfAction()
    {
        $generated = new \DateTime('now');
        $genetared = $gerado->format('d/m/Y H:i:s');

        $pdf = new PdfModel();
        $renderer = $this->getServiceLocator()->get('ViewPdfRenderer');
        $renderer->getEngine()->setHTMLHeader('<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-bottom: 1px solid #000"><tr>
<td width="33%"><span style="font-weight: bold; font-style: italic;">Client</span></td>
<td width="33%" align="center" style="font-weight: bold; font-style: italic;">Report Name</td>
<td width="33%" style="text-align: right; ">My Company</td>
</tr></table>
');
        $renderer->getEngine()->setHTMLFooter('Footer', '<table width="100%" style="vertical-align: bottom; font-family: serif; font-size: 8pt; color: #000000; font-weight: bold; font-style: italic; border-top: 1px solid #000"><tr>
<td width="50%" style="text-align: left; font-weight: bold; font-style: italic;">Generated: '.$generated.'</td>
<td width="50%" style="text-align: right; ">Page {PAGENO}</td>
</tr></table>
');

        $pdf->setTerminal(true);
        $pdf->setVariables(['name'=>'Leandro']);
        $pdf->setOption("paperSize", "a4");
        $pdf->setTemplate('site/index/pdf');
        $output = $renderer->renderToString($pdf);
        $renderer->renderToFile($pdf, '/tmp/report.pdf');
        
        return $pdf;
    }
