Magento – insert new attribute option programmatically

April 26th, 2012 by laeeq | 2 comments

As We know, its not easy at first to add new attribute options from code in Magento. it took time to find out solution. Actually the main problem is that we need to get the option value of new option after saving that’s essentail point when doing this from Magento.

We can find many functions that allow you to insert new attribute option. In order having option value, I tried to reload options list via Magento attribute model object but we meet Magento cache issue which you never get the new option saved with getAllOptions function.

At last , I got a solution which calling attribute source table directly to read all attribute options. Below are 2 usefull functions which is ready for you to use in your code

Function 1:

view plaincopy to clipboardprint?
  1. public function addAttributeValue($arg_attribute, $arg_value)
  2. {
  3. $attribute_model        = Mage::getModel(‘eav/entity_attribute’);
  5. $attribute_code         = $attribute_model->getIdByCode(‘catalog_product’, $arg_attribute);
  6. $attribute              = $attribute_model->load($attribute_code);
  8. if(!$this->attributeValueExists($arg_attribute, $arg_value))
  9. {
  10. $value['option'] = array($arg_value,$arg_value);
  11. $result = array(‘value’ => $value);
  12. $attribute->setData(‘option’,$result);
  13. $attribute->save();
  14. }
  16. $attribute_options_model= Mage::getModel(‘eav/entity_attribute_source_table’) ;
  17. $attribute_table        = $attribute_options_model->setAttribute($attribute);
  18. $options                = $attribute_options_model->getAllOptions(false);
  20. foreach($options as $option)
  21. {
  22. if ($option['label'] == $arg_value)
  23. {
  24. return $option['value'];
  25. }
  26. }
  27. return false;
  28. }

Function 2:

view plaincopy to clipboardprint?
  1. public function attributeValueExists($arg_attribute, $arg_value)
  2. {
  3. $attribute_model        = Mage::getModel(‘eav/entity_attribute’);
  4. $attribute_options_model= Mage::getModel(‘eav/entity_attribute_source_table’) ;
  6. $attribute_code         = $attribute_model->getIdByCode(‘catalog_product’, $arg_attribute);
  7. $attribute              = $attribute_model->load($attribute_code);
  9. $attribute_table        = $attribute_options_model->setAttribute($attribute);
  10. $options                = $attribute_options_model->getAllOptions(false);
  12. foreach($options as $option)
  13. {
  14. if ($option['label'] == $arg_value)
  15. {
  16. return $option['value'];
  17. }
  18. }
  20. return false;
  21. }
