php - CANNOT RENDER A PDF FILE,OBTAINING TEXT FILE INSTEAD OF A PDF -
in cakephp 3.x , using plugin cakepdf
i tried wkhtmltopdf , dompdf , both of them had same problem>>> cannot download real pdf file, downloads plain text file.
my bootstrap.php:
plugin::load('cakepdf', array('bootstrap' => true, 'routes' => true)); routes.php: ....... router::scope('/users/view', function ($routes) { $routes->extensions('pdf'); $routes->connect('/view/*', ['controller' => 'users', 'action' => 'view']); $routes->fallbacks('inflectedroute'); }); router::scope('/', function ($routes) { ...... everything ok, when click in browser this:
/cakephp/users/view/5.pdf
i dont proper pdf file, instead of download text file (the view ctp seems work)...any idea??? :
<!doctype html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> <title> users\pdf </title> <link rel="stylesheet" href="http://localhost/fct/css/style.css"/></head> <body> <h2>informe pdf</h2> <div id="container"> <div id="content"> <div class="users view"> <h2>user</h2> <dl> <dt>id</dt> <dd> 2 </dd> <dt>username</dt> <dd> tutor666 </dd> <dt>created</dt> <dd> 8/5/16, 7:34 pm </dd> <dt>modified</dt> <dd> 8/5/16, 7:34 pm </dd> </dl> </div> </div> </div> </body> </html> so maybe router.php wrong?... router::scope('/users/view', function ($routes) { $routes->extensions('pdf'); $routes->connect('/view/*', ['controller' => 'users', 'action' => 'view']); $routes->fallbacks('inflectedroute'); –
reviewing cakepdf docs seems "/cakephp/users/view/5.pdf" right way....but stills download text file instead of pdf file. feel desperate!!! –
the file should 'user_15.pdf' '15.pdf, maybe code not working: userscontroller:view(): $this->viewbuilder()->options([ 'pdfconfig' => [ 'orientation' => 'portrait', 'filename' => 'user_' . $id . '.pdf' ] ]);
i @ debug history , says "get 200 application/pdf " can see above download text/text header.
here how implement cakepdf. use dompdf can installed via composer.
step 1. install cakepdf plugin
composer require friendsofcake/cakepdf step 2. install dompdf engind
composer require dompdf/dompdf step 3. make sure have requesthandler component loaded in appcontroller.php ([rootdir]/src/appcontroller.php)
public function initialize() { parent::initialize(); $this->loadcomponent('requesthandler'); } step 4. enable cakepdf plugin in bootstrap.php
plugin::load('cakepdf', ['bootstrap' => true]); step 5. setup appropriate routes in routes.php
router::scope('/', function (routebuilder $routes) { $routes->extensions(['pdf']); /** other route setup **/ $routes->fallbacks(dashedroute::class); }); step 6. create pdf folder under templates/layouts folder , create pdf.ctp file contain following
<?= $this->fetch('content'); ?> the above acts blank layout pdf. can use whatever markup appropriate case
step 7. in template folder want generate pdfs in cases users (i'm assuming [rootdir]/templates/users/), create pdf folder , create view file in pdf folder (i.e [rootdir]/templates/users/pdf/view.ctp). contain markup view. example use
<?= $show;?> step 8. in controller function (assuming view also). should contain following
public function view () { /** i'm displaying "text" on pdf file **/ $show = "text"; $this->viewbuilder()->options([ 'pdfconfig' => [ 'engine' => 'cakepdf.dompdf', 'orientation' => 'portrait', 'filename' => 'pdf view' /** other config options can go here**/ ] ]); $this->set(compact('show')); $this->set('_serialize', ['show']); } step 9. point browser [webpath]/users/view.pdf , should have pdf file showing "text"
you can adapt needs
cheers.
