mPDF temporary file is not writable using Yii
I tried to print a certificate in PDF but when I push my code to staging, it said
Temporary files directory "/var/www/protected/vendor/mpdf/mpdf/src/Config/../../tmp" is not writable
I'm not sure how to change the permission and how to change the custom directory.
Here's my code of a button to click to get the certificate:
<a class="btn btn-sd btn-sd-ghost btn-sd-ghost-black margin-right-lg" href="<?php echo $this->createUrl('//idea/frontend/pdf', array('id'=>$model->id))?>" target="_blank">Get Your Certificate<i class="icon-right-small"></i></a>
<?php endif; ?>
and this is the controller:
public function actionPdf($id){
$model = HUB::getOrganization($id);
$orgtitle = $model->title;
$mpdf = new \Mpdf\Mpdf(['mode' => 'utf-8', 'format' => 'A4-L']);
$mpdf->WriteHTML("<html><body style='background-image:url(\"/images/cert-idea.jpg\"); background-image-resize: 5; background-position: top center;'></body></html>");
$mpdf->WriteHTML("<div style='text-align:center; display:table; height:100%; width:100%; padding-top:28%;'><h1 style='display:table-cell; vertical-align:middle; font-size:40px;'>".$orgtitle."</h1></div>");
$mpdf->Output('IDEA-CERT-'.$orgtitle.'.pdf', 'I');
}
Hope someone can help on my issue. Thank you!
Answer
Try a custom temporary directory as stated in the documentation:
It is recommended to set custom temporary directory via
tempDirconfiguration key. The directory must have write permissions (mode 775 is recommended).
<?php
$mpdf = new \Mpdf\Mpdf(['tempDir' => __DIR__ . '/custom/temp/dir/path']);
You will have far more control over permissions of a directory outside composer vendor-dir.
Mode 775 may not be sufficient if a web-server user, typically www-data has to access the directory. Use 777 if necessary.
Be warned that mPDF auto-cleans its temporary directory, so use one dedicated only to mPDF.
