multiselect product attribute not showing option labels on frontend

Question

I have checked lot and tried many things, but I am still not getting the product multiselect selected values label on product view page.

I have product attribute called package which is multiselect, Code that create the product attribute

$this->addAttribute(
 'catalog_product',
 'package',
 array(
 'group' => 'Package',
 'backend' => 'eav/entity_attribute_backend_array',
 'frontend' => '',
 'class' => '',
 'default' => '',
 'label' => 'Package',
 'input' => 'multiselect',
 'type' => 'text',
 'source' => 'npm_recurrex/package_source',
 'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
 'is_visible' => 1,
 'required' => 0,
 'searchable' => 0,
 'filterable' => 0,
 'unique' => 0,
 'comparable' => 0,
 'visible_on_front' => 0,
 'user_defined' => 1,
 )
);

this works fine, I am successfully saving the product. But in frontend product view page when I say

Mage::log(print_r($_product->getData('package'), true));

Its prints the result as 1,2 But I wanted to display option labels of multiselect not option id's. So I tried with this code

Mage::log(print_r($_product->getAttributeText('package'), true));

It prints nothing, just blank space :(.

I have checked this link but no use.

I am confused with this, Where I am wrong? and what is the wrong thing?

Can anybody explain me what is happening in my case?

my getOptionText Method

public function getOptionText($value)
{
 $options = $this->getAllOptions(false);
 foreach ($options as $item) {
 if ($item['value'] == $value) {
 return $item['label'];
 }
 }
 return false;
}

The method getAttributeText looks like this:

public function getAttributeText($attributeCode)
{
 return $this->getResource()
 ->getAttribute($attributeCode)
 ->getSource()
 ->getOptionText($this->getData($attributeCode));
}

Notice the last 2 lines.
They mean that the method calls getOptionText from the source model class.
I see that your attribute has a custom source model npm_recurrex/package_source. Make sure that model has the method getOptionText or it's parent class has it and returns what your need.

[EDIT]
Your getOptionText is wrong.
It would work if the attribute would be of type select.
But it doesn't work for multiselects.
Here is a scenario. Actually I'm using your scenario.
$_product->getData('package') returns 1,2.
And I assume your options are something like this:

$options[] => array('value' => 1, 'label'=>'Option 1');
$options[] => array('value' => 2, 'label'=>'Option 2');
$options[] => array('value' => 3, 'label'=>'Option 3');
$options[] => array('value' => 4, 'label'=>'Option 4'); 

In this case, your method receives as parameter 1,2 and you check if there is an element in $options with value = 1,2. and there isn't.
Try to make your method look like this:

public function getOptionText($value)
{
 $options = $this->getAllOptions(false);
 $optionsByValue = array();
 foreach ($options as $item) {
 $optionsByValue[$item['value']] = $item['label'];
 }
 $values = explode(',', $value);
 $returnValue = array();
 foreach ($values as $_value) {
 if (isset($optionsByValue[$_value])) {
 $returnValue[] = $optionsByValue[$_value];
 }
 }
 return implode(', ', $returnValue);
}

Untested code so look out for typos.

• Charlie: Yes, My getOptionText method is present in npm_recurrex/package_source source model and it also contains the getAllOptions, toOptionArray, getFlatColums.
• Marius: @Charlie Please post the getOptionText method in the question
• Charlie: I have added the content of getOptionText Method
• Marius: @Charlie. I've updated the code. See if it helps.
• Charlie: Yes, You are awesome, You finally helped lot me to get that issue. getAttributeText working now. Thank you Marius
