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 have small problem with changing size of the product image only on product page.
I know that from admin I can change the size for all thumb pictures.
But how to make bigger images only on the product page and I am not talking about additional images section...
Can anyone explain to me where $thumb variable is defined as i made search in almost all php files but I cannot find $thumb declaration...????
In product.tpl
Code:
<div id="product">
<div class="a"><img src="<?php echo $thumb; ?>" title="<?php echo $heading_title; ?>" alt="<?php echo $heading_title; ?>"><br>
<?php echo $text_enlarge; ?></div>
Now in this bit taken from product.tpl I see that path for the image is taken from the variable called $thumb.
I want Opencart to:
Prepare for me medium sized image
Generate for it path that will be stored in $medium variable which I can call in this place and simply have the code like this:
Code:
<div id="product">
<div class="a"><img src="<?php echo $medium; ?>" title="<?php echo $heading_title; ?>" alt="<?php echo $heading_title; ?>"><br>
<?php echo $text_enlarge; ?></div>
Anyone please help...
Before you start work in opencart, You should have to understand the basic knowledge of opencart MVC-L (i.e. How opencart module works)
Here is the Tutorial
$thumb which is defined in product.tpl file is declared in its controller file ( catalog/product/product.php ) named $data['thumb'].
Maximum variables used in product.tpl file are defined in modules controller file.
To more information, Check the above shared tutorial.
If I click on a product from my product overview on the left side, the shop does not load with the list.phtml. As soon as I swap view to grid or list, it swaps to the list.phtml file and everything is fine. But as I said, if I click on the products on the sidebar, it doesnt work (it's not even affected by list.phtml at all). I removed all the code inside it and it still showed (a bit different, that's why I want to change it) the products, but as soon as I swapped mode, everything disappeared -- as it should. Do you know where I can change that?
Thank you.
It should use list.phtml file. In that file it is defined for both list mode and grid mode.
<?php echo $this->getToolbarHtml() ?>
<?php // List mode ?>
<?php if($this->getMode()!='grid'): ?>
<?php $_iterator = 0; ?>
And
<?php else: ?>
<?php // Grid Mode ?>
<?php $_collectionSize = $_productCollection->count() ?>
You can see something like above code in your list.phtml file,one is for list mode and another for grid mode. This is the default case unless you haven't changed the layout or template code.
If you want to know the file location than you can always enable template path hint. If you don't know how to do that you can follow this.
After knowing from which file it is rendering you can fix it.
Hope this will help.
I want to make a relatively simple modification to OpenCart so that if there are no Special Offers available, or applicable, that the title Special Offers does not display.
If none are available or applicable, currently it will display the heading title on a coloured background which looks odd if there are no special offers to show.
I am guessing the modification needs to be made to /catalog/controller/module/special.php and would be something like.
If special offers > 0 then do this
else
Don't do anything
But I am not sure how to implement this.
I'd be grateful if someone could advise.
Not entirely sure what you are referring to here, but you would be best editing the template not the controller file and using
<?php if($products) { echo $heading_title; } ?>
in place of what is there currently - something like just <?php echo $heading_title; ?>
Also you may find the title is surrounded by <h1> or <h2> tags. If so, just do the same but around the tags, something like
<?php if($products): ?>
<h2><?php echo $heading_title; ?></h2>
<?php endif; ?>
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!
Hy,
I'm look for a way to do this on symfony:
I've to use a "box" a bit every where on my site... this box is resizable ... so the html/css is not simple... and i don't want to copy/paste it every where and the content of this box is not constant at all... so its not possible to make a partial template with a object variable... and pass all the content on a variable it's a bit annoying.
someyhing like this would be great:
<?PHP begin("mytemplate") ?>
"html content"
<?PHP end ?>
thanks for your help
Everywhere you need this "box" try this:
include_partial('mymodule/mypartial', array('variable1' => 'value1', 'variable2' => 'value2'));
and in your "mymodule/templates/_mypartial.php" use it like:
<div class="box"><?php echo $variable1 ?></div>
If you don't want to use partials you can use components and define each variable into the component action. Check Symfony's Components Slots (this is for v1.2 but works in v1.4).
