I want to pass a variable with the block code like of JSON type in magento,
{{block type="multibanners/multibanners" category_id="9" name="multibanners" alias="multibanners" template="multibanners/multibanners.phtml"}}
from cms pages content area , but I don't receive any thing.
If I use block with action method than I easily get my value.
Anyone know how can I pass variable with my custom block?
I'm not 100% sure what you are asking, but if you are trying to pass a variable to multibanners.phtml
from the code above then you could create another attribute similar to category_id="9"
and in multibanners.phtml
you could get the value using $this->getData("category_id");
e.g.
{{block ... my_var="value here" ... template="multibanners/multibanners.phtml"}}
In multibanners.phtml
:
$this->getData('my_var');
I think the problem here stems from the block type you are calling. When you define a type, you're telling Magento to load that model and pass it the appropriate data - which then only exposes the functions defined on that specific model.
A better solution may be to reference the core block type "core/template" which exposes the ->getData() method, and then load the "multibanners/multibanners" model to work with and output the data.
{{block type="core/template" category_id="9" name="multibanners" alias="multibanners" template="multibanners/multibanners.phtml"}}
I'm not sure what the proper syntax is to load 'multibanners', but in the multibanners.phtml would be something like this:
<?php
$catId = $this->getData('category_id');
$multibanner = Mage::getModel('multibanners/multibanners')->load($catId);
/**
** Generate some output here.
*/
?>
I found this very useful and I thought I'd explain what I did in case it helps anyone else.
I have a few static blocks that I use to build some static pages with basic non-changing information (about-us type pages) which include some photos. The photos are very large (for a web page) and I wanted to use Magento's resizing facility. The only way I could work out to do this was to use the ideas here. I now have a block I can include on any cms static page/block when I want to have a resized image with several parameters. It's like a subroutine (am I allowed to say that?! ;o). Anyway, here's what I did.
The block:
{{block type="core/template" name="display_resized_img" gimg="IMG_0559.JPG" gsize="300" gpath="/wysiwyg/ShopFront/" gclass="about-us" galt="The shop" template="utilities/display_resized_img.phtml"}}
and the phtml code file:
<?php
/*
* Displays and resizes an image as requested from the block.
* The image is only resized if it hasn't been already.
*/
$img = $this->getData('gimg');
$size = $this->getData('gsize');
$path = $this->getData('gpath');
$class = $this->getData('gclass');
$alt = $this->getData('galt');
$resizePath = Mage::getBaseDir ('media') . $path . "resized/" . $size . $img;
if (!file_exists($resizePath)):
$imagePath = Mage::getBaseDir('media') . $path . $img;
$imageObj = new Varien_Image($imagePath);
$imageObj->constrainOnly(TRUE);
$imageObj->keepAspectRatio(TRUE);
$imageObj->keepFrame(FALSE);
$imageObj->resize($size, null);
$imageObj->save($resizePath);
endif;
$resizeUrl = Mage::getBaseUrl ('media') . $path . "resized/" . $size . $img;
?>
<img class="<?php echo $class; ?>" src="<?php echo $resizeUrl ?>" alt="<?php echo $alt; ?>">
Note I save my re-sized images in a resized folder and add the new size to the image filename so I can easily see what's happening and manage the files.
Thanks for reading!
When adding block on a cms pages remove style from block code.
{{block type="multibanners/multibanners" name="multibanners" alias="multibanners" template="multibanners/multibanners.phtml" category_id="8"}}
To get the category_id in your phtml or Block use $this->getCategoryId()
.
