I try to get id of module by position in templates/mytemplate/index.php (Joomla 3.3.3) and use the code:
jimport( 'joomla.application.module.helper' );
$module = JModuleHelper::getModule('top');
echo $module->id;
but I get nothing. What's wrong?
With JModuleHelper::getModule, you are only allowed to define the name or type of the module. You cannot define the position. So instead, type in the name, for example:
jimport( 'joomla.application.module.helper' );
$module = JModuleHelper::getModule('login');
echo $module->id;
If you still want to get the module by position, then you must use JModuleHelper::getModules. Note the s at the end.
Update:
As the second option will give you an array of multiple modules that belong to that position, you will need to use the following which will give you the first instance of the array:
echo $modules[0]->id;
Hope this helps

I know i can get all segments from url like this
Lets say i have this example link
www.example.com/de/products.html
Using url_helper like this:
$data['url'] = $this->uri->uri_string();
I will get value like this
de/products
But i dont need first segment de, only products, the problem is that
i dont know how many segments it will be, i only need to remove the first
Is there possible to forget first segment with url helper in CI?
Try like this...
Use the php's explode() function to make the url string as array.Then apply array's array_shift() function which always removes the first element from array.
Code is looks like as below
$data= $this->uri->uri_string();
$arr=explode('/', $data);
array_shift($arr);
//print_r($arr);
Then use the php's implode() method to get the URI without first segment.Hope it will works...
$uri=implode('/',$arr);
echo $uri;
There is no URL helper in the CI to forget the first segment. However you can easily make a custom one and put #Hikmat's answer below it in the application/helpers/MY_url_helper.php in the Core folder.
e.g.
function my_forget_first_segment() {
$data= $this->uri->uri_string();
$arr=explode('/', $data);
array_shift($arr);
$uri=implode('/',$arr);
return $uri;
}
Before Edit answer.
You need to try this
$second_segment = $this->uri->segment(2);
From Codeigniter documentation -
$this->uri->segment(n);
Permits you to retrieve a specific segment. Where n is the segment number you wish to retrieve. Segments are numbered from left to right. For example, if your full URL is this:
http://example.com/index.php/news/local/metro/crime_is_up
The segment numbers would be this:
1. news
2. local
3. metro
4. crime_is_up
The optional second parameter defaults to NULL and allows you to set the return value of this method when the requested URI segment is missing. For example, this would tell the method to return the number zero in the event of failure:
$product_id = $this->uri->segment(3, 0);
example:
<?php
$data=$this->uri->segment(2);
$val=explode('.', $data);
echo $val[0];
?>
I'm using a script to programmatically create attribute options - the code is as follows:
echo "Creating option ....\n";
$attr_model = Mage::getModel('catalog/resource_eav_attribute');
$attr = $attr_model->loadByCode('catalog_product', $key);
$attr_id = $attr->getAttributeId();
if (!$attr_id){
echo "Cannot find Attribute $code\n";
return 0;
}else{
$option['attribute_id'] = $attr_id;
$option['value'][$value][0] = $value;
$option['value'][$value][1] = $value;
$setup = new Mage_Eav_Model_Entity_Setup('core_setup');
$setup->addAttributeOption($option);
}
And for most values it's working absolutely fine.
However certain values are not being created - it's not throwing any errors, but it doesn't create the options.
One example is 55 mg/kg, which makes me suspect that it's an escaping issue.
Are there any particular escaping rules that I need to follow for this?
Having dug into this further, I've found out that if the array key you use in the $option['value'] array starts with a number, Magento treats this differently as part of the addAttributeOption() call (casting it as an (int), and then assuming you are editing an existing attribute option)
Ensuring the array key doesn't start with a number (I did this by pre-pending 'opt' onto the key) solves the issue.
I have stored a variable in register by Mage::register('captcha', $var); in helper. And in the controller i tried to retrieve the variable by using Mage::registry('captcha'); But i dont getting any values here. Please help me to solve this.
In your helper file create a function like below :
public function getCaptcha(){
$var = 'myValue123';
Mage::register('varun', $var);
return Mage::registry('varun');
}
In your controller function:
$registryValue = Mage::helper('yourModule')->getCaptcha();
echo registryValue ; //prints myValue123
Hope it helps !!!
It's look like syntax is right.
Please first try to set some static value like $var="test"
Mage::register('captcha', $var);
after that got this value in controller.
Mage::registry('captcha');
if you got this value test then i think you have problem with $var in your helper.
Let me know if you have any problem
'captcha' is already in use, so magento never set your data in registry. Change the name, for example 'captcha1'
Mage::register('captcha1', $var);
I am trying to do this route trick:
$route['cp/roles/:num'] = "cp/roles/index/:num";
but it doesn't work :(
please help me!!
advanced thanks .
According to the documentation on URI Routing:
$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";
“A URL with "product" as the first segment, and a number in the second will be remapped to the "catalog" class and the "product_lookup_by_id" method passing in the match as a variable to the function.”
So, for your particular instance, you would do the following:
$route['cp/roles/(:num)'] = "cp/roles/index/$1";
You could try
$route['cp/roles/:num'] = "cp/roles";
and then instead of passing a variable in your function you use
$this->uri->segment(3);
or the number that correspond to the segment.
Magento can add a suffix that is defined by the user to append onto urls. I want to get that suffix from my code. Does anyone know an easy way to do this?
If it's stored in the configuration area, then you access it just as you would any other configuration value, by using Mage::getStoreConfig($config_path) where $config_path is defined in the system.xml of the module that defines it.
If you're not sure of the $config_path, then I usually cheat and inspect the textbox/dropdown in the configuration section, take a look at the id, e.g. dev_log_file, and translate it to dev/log/file. You'll need to use some intelligence when there are multiple _ though :)
Nick's answer is good but the actual answer to this question is:
$suffix = Mage::helper('catalog/category')->getCategoryUrlSuffix();
If I am not mistaken, here is the code ( because I don't understand what you want with URL )
<?php
$currentUrl = $this->helper('core/url')->getCurrentUrl();
$url_parts = split('[/.-]', $currentUrl); // escape characters should change based your url
echo $url_parts[0]; //check here
?>
complete product url:
$productId = ***;
$productUrl = Mage::getBaseUrl().Mage::getResourceSingleton('catalog/product')->getAttributeRawValue($productId, 'url_key', Mage::app()->getStore()).Mage::helper('catalog/product')->getProductUrlSuffix();
