I have included the files properly as shown below,
require_once DIR_ROOT . '/vendor/dompdf/autoload.inc.php';
use Dompdf\Dompdf;
I'm creating object as mentioned in one of the tutorial
// instantiate and use the dompdf class
$dompdf = new Dompdf();
$dompdf->loadHtml('hello world');
This is working fine on my localhost. But It is failinng to create object $dompdf = new Dompdf(); on our server. I'm using opencart.
It worked after installing mb_string module on my server.
I was struggled more than one month to solve this finally solved...
solution is
<?php
require_once 'dompdf/autoload.inc.php';
// reference the Dompdf namespace
use Dompdf\Dompdf;
?>
<html>
<head>
</head>
<body>
<h1>Sucess</h1>
</body>
</html>
<?php
$html = ob_get_clean();
$dompdf = new DOMPDF();
$dompdf->setPaper('A4', 'portrait');
//$dompdf->setPaper('A4', 'landscape');
$dompdf->load_html($html);
$dompdf->render();
//For view
$dompdf->stream("",array("Attachment" => false));
// for download
//$dompdf->stream("sample.pdf");
?>
Yes localhost code is not work on the server. I solved it.
change the php version to 7 and test.

I can't seem to get any sample app working. I'm trying to run a simple websocket 101 starter app that does nothing more than log something to console.
I have cfws directory in my webroot C:\inetpub\wwwroot, and I'm working in C:\inetpub\wwwroot\site\.
I have enabled web sockets in the cfadmin, with "use proxy" option, port 8579.
The code I'm running is:
index.cfm:
<html>
<head>
<title>Example One</title>
<script language="javascript">
function messageHandler(msg) {
console.log("messageHandler Run");
console.dir(msg);
}
</script>
</head>
<body>
<h1>Example One</h1>
</body>
</html>
<cfwebsocket name="myWS" onMessage="messageHandler" subscribeTo="news">
Application.cfc
component {
this.name="cfwack2_1";
this.wschannels = [{name:"news"}];
}
I run the code and there are no errors, but I don't see the expected log in the console.
So far every sample app I've tried does five eighths of nothing. Any help appreciated.
You may have a typo in your Application.cfc. According to the docs here, it should look like this:
component {
this.name="cfwack2_1";
this.wschannels=[{name="news"}];
}
An = (equal sign) instead of a : (colon) after name.
The documentation also shows that the JavaScript function should accept an event and a token value. Here is the example from the documentation.
<script type="text/javascript">
function mymessagehandler(aevent, atoken)
{
var message = ColdFusion.JSON.encode(atoken);
var txt=document.getElementById("myDiv");
txt.innerHTML +=message +"";
}
</script>
<cfwebsocket name="mycfwebsocketobject" onmessage="mymessagehandler" subscribeto="news">
<cfdiv id="myDiv"></cfdiv>
using vqmod i inject this code in header.tpl.
<?php if ($this->customer->isLogged()){ if($this->customer->getCustomerGroupId()!=1) { ?>
//show something
<?php } ?>
It worked fine in opencart 1.5.6.1 But now I updated to 2.0.3.1 and I get this error:
Notice: Undefined property: Loader::$customer in C:\UniServerZ\www\opencart-2.0.3.1\upload\vqmod\vqcache\vq2-catalog_view_theme_default_template_common_header.tpl
Is there a way to refer to $this from a .tpl file in 2.0.3.1 ?
You can't call customer class from tpl, you have do this in header.php,
store the data in to the $this->data[] and use it in the tpl file. That will be the right procedure.
If you wants to user any library file in .tpl file in OC then you have to create instance of that class first then you can access it, try this one
$customer = new Customer();
$customer->isLogged()
Latest opencart(ver 2.x) remove $this concept. so you will directly using
$customer->isLogged()
I am beginning to use Opencart and I am making my own template by copying the default template.
When I was going through template/common/header.tpl, I see the following lines
<?php foreach ($styles as $style) { ?>
<link rel="<?php echo $style['rel']; ?>" type="text/css" href="<?php echo $style['href']; ?>" media="<?php echo $style['media']; ?>" />
<?php } ?>
I have been thinking for a while, how it is getting populated. Though I have changed the theme to be used as my new theme, it is still populated with old default stylesheets. I will be really thankful if anyone can point me to the direction I have missed. I am sorry if it is a naive question.
Styles get added to the array using $this->document->addStyle() by the various controller classes. The $this->document class is located in /system/library/document.php if you want to see the source code for the method
i was wondering if this setup would work. i have to crank out a batch of PDF from a bunch of variables i'm pushing into the $_SESSION via a form (duh...). the idea is to pass the template file to the dompdf engine and have the template populate from the $_SESSION then out to PDF. it seems to me that when the $template gets loaded it should do that, yes?
here's the basic code:
<?php
function renderToPDF($theTemplate = "template.php") // this is just to show the value
{
require_once("dompdf/dompdf_config.inc.php");
$content = file_get_contents($theTemplate);
if ($content !== false)
{
$dompdf = new DOMPDF();
$dompdf->load_html($content);
$dompdf->render();
$dompdf->stream("kapow_ItWorks.pdf");
}
}
?>
and this is the template.php file (basically... you don't want all 16 pages...)
<html>
<meta>
<head>
<link href="thisPage.css" type="text/css" rel="stylesheet">
</head>
<body>
<h1><?php echo $_SESSION['someTitle'] ?></h1>
<h2>wouldn't it be nice, <?php echo $_SESSION['someName'] ?></h2>
</body>
</html>
so my thinking is that the template.php will pull the variables right out of the $_SESSION array without any intervention, looking like this:
BIG TITLE
wouldn't it be nice, HandsomeLulu?
i guess the nut of the question is: Do $_SESSION variables get evaluated when PHP files are loaded, but not rendered?
WR!
file_get_contents does not evaluate the PHP file, it simply gets its contents (the file as it is in the hard drive).
To do what you want, you need to use output buffering and include.
ob_start(); // Start Output beffering
include $theTemplate; // include the file and evaluate it : all the code outside of <?php ?> is like doing an `echo`
$content = ob_get_clean(); // retrieve what was outputted and close the OB
for some reason, the code ON the page that calls the function ALSO gets dumped into the file. this was placed before the header. i understand now why: i wasn't referencing an external page, i was importing and external page. don't know why that didn't click.
anyway. as soon as i got rid of the page's extra stuff, it worked just fine. in retrospect, what dompdf needed to state was quite simply that NO HTML of ANY kind (echo, print, &c.) can be on the page that calls the function. at least that what it appears to require at this level of my knowledge.
for those who, like me, are floundering in a misma of 'everything but the answer', here's the bare bones code that did the job:
buildPDF.php:
<?php
session_start();
$_SESSION['someTitle'] = "BIG FAT TITLE";
$_SESSION['someName'] = "HandomeLu";
$theTemplate = 'template.php';
function renderToPDF($templateFile)
{
require_once("_dox/dompdf/dompdf_config.inc.php");
ob_start();
include $templateFile;
$contents = ob_get_clean();
if ($contents !== false)
{
$dompdf = new DOMPDF();
$dompdf->load_html($contents);
$dompdf->render();
$dompdf->stream("kapow_ItWorks.pdf");
}
}
renderToPDF($theTemplate);
?>
and this is the template.php:
<!DOCTYPE HTML>
<html>
<meta>
<head>
<meta charset="utf-8">
<link href="thisPage.css" type="text/css" rel="stylesheet">
</head>
<body>
<h1><?php echo $_SESSION['someTitle'] ?></h1>
<p>wouldn't it be nice, <?php echo $_SESSION['someName'] ?></p>
</body>
</html>
also note that the external CSS file reads in just fine. so you can still keep the structure and style separate. also, the $_SESSION variables can be set anywhere, obviously, i just set them here to keep testing easy.
hope this is useful for those getting started with this GREAT class. if you're looking to get up and running cranking out PDF files, this kicks so much butt, it should have a trigger and a grip on it. :)
thanks to everyone who commented. you got me in the place i needed to be. :)
this site ROCKS.
WR!
I have an app where I need to call some JS in the onLoad event of the BODY tag of two forms. However, I can't find how to modify the tag for just them. Does anyone know?
Frank
inkedmn certainly has provided the right answer for this case, but in general, you can "hand information up" like this:
(in views/controller/view.ctp)
$this->set('bodyAttr', 'onload="something"');
(in views/layouts/default.ctp)
<?php
if (isset($bodyAttr)) {
$bodyAttr = " $bodyAttr";
} else {
$bodyAttr = null;
}
?>
<body<?php echo $bodyAttr; ?>>
I often use it like this to add extra classes to a "top level element":
<?php
if (!isset($docClass)) {
$docClass = null;
}
?>
<div id="doc" class="<?php echo $docClass; ?>">
You don't need to modify the body tag to have Javascript execute when the page loads. You could just include something like this in your layout where appropriate:
(jQuery)
$("body").load(
function(){
// do stuff when the body element is loaded.
}
);
Or, if you want to have the code execute when the document.ready event fires:
$(function(){
// do stuff when the document is ready
}
);
Or, if you don't want to use jQuery, you could do something like this:
function doStuff(){
// whatever you want to happen when the load completes
}
window.onload = dostuff;
Good luck - and please clarify your question if this answer isn't satisfactory.
I do the following:
We apply $ bodyLoad in my body
<body <? = (isset ($ bodyLoad)? 'onload = \''. $ bodyLoad.' \'',''); ?> >
Already in my [action]. Ctp, I do the following:
<? php $ this-> set ('bodyLoad', 'field.focus ();');?>
If you want you can also put this code in the controller.
Good luck
