Magento How to update bundle product programmatically - magento

Question

I am reading product sku from csv file and my csv file contains bundle product sku. I am traversing through csv data and for each bundle sku I want to add bundle items inside it which I am passing through CSV
Here is the code what I have done
ini_set('auto_detect_line_endings', TRUE);
$magentoPath = getcwd();
require_once ($magentoPath . '/includes/config.php');
require_once ($magentoPath . '/app/Mage.php');
Mage::app();
//read the csv
$bundleCsv = Mage::getBaseDir('var').'/import/bundleImport.csv';
$rows = array_map('str_getcsv', file($bundleCsv));
$header = array_shift($rows);
$csv = array();
foreach ($rows as $row) {
$csv[] = array_combine($header, $row);
}
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
echo Mage::app()->getStore()->getId(); exit;
foreach( $csv as $key => $val ){
if( !isset($val['sku']) || empty($val['sku']) || $val['sku'] == '' ){
echo 'Not Valid Sku';
continue;
}
$_product = Mage::getModel('catalog/product')->loadByAttribute('sku',$val['sku']);
$opt = $val['bundle_options'];
$optArr = explode(':', $opt);
$bundleOptions = array();
$bundleSelections = array();
foreach ( $optArr as $key1 => $val1 ) {
$valTemp = explode( '(', $val1 );
$title = trim($valTemp[0]);
$bundleSub[$key1] = array(
'title' => $title, // option title
'option_id' => $key1,
'delete' => '',
'type' => 'select', // option type
'required' => '1', // is option required
'position' => '1' // option position
);
$skuStr = trim($valTemp[1]);
$skuStrTemp = explode( ')', $skuStr );
$skuStr = trim($skuStrTemp[0]);
$skuTemp = explode( '+', $skuStr );
foreach( $skuTemp as $key2 => $val2 ){
$product = Mage::getModel('catalog/product');
$id = Mage::getModel('catalog/product')->getResource()->getIdBySku($val2);
if( $id ){
$bundleSelectionsSub[$key2] = array ( // selection ID of the option (first product under this option (option ID) would have ID of 0, second an ID of 1, etc)
'product_id' => $id, // if of a product in selection
'delete' => '',
'selection_price_value' => '10',
'selection_price_type' => 0,
'selection_qty' => 1,
'selection_can_change_qty' => 0,
'position' => 0,
'is_default' => 1
);
$product = null;
}else{
continue;
}
}
$bundleSelections[$key1] = $bundleSelectionsSub;
}
$bundleOptions = $bundleSub;
//echo '<pre>'; print_r($bundleOptions); exit;
try{
$_product->setCanSaveCustomOptions ( true );
$_product->setCanSaveBundleSelections ( true );
$_product->setAffectBundleProductSelections ( true );
$_product->setBundleOptionsData ( $bundleOptions );
$_product->setBundleSelectionsData ( $bundleSelections );
$_product->save();
}catch ( Exception $e ) {
Mage::log ( $e->getMessage () );
echo $e->getMessage ();
}
echo 1; exit;
$_product = null;
}
But this gives me following error as
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`aero_dev`.`catalog_product_bundle_option_value`, CONSTRAINT `FK_CAT_PRD_BNDL_OPT_VAL_OPT_ID_CAT_PRD_BNDL_OPT_OPT_ID` FOREIGN KEY (`option_id`) REFERENCES `catalog_product_bundle_option` (`opt), query was: INSERT INTO `catalog_product_bundle_option_value` (`option_id`, `store_id`, `title`) VALUES (?, ?, ?)
Any help would be appreciated.

I could not get it working using above approach so I tried to write custom query to put bundle items in the existing bundle product. When I looked into db I found there are basically 3 tables involved to create bundle items. These are
catalog_product_bundle_option
catalog_product_bundle_option_value
catalog_product_bundle_selection
I went through these tables and tried to looked for what magento puts If I create bundle items from magento admin.
So after some research I have done something like -
foreach( $csv as $key => $val ){
if( !isset($val['sku']) || empty($val['sku']) || $val['sku'] == '' ){
echo 'Not Valid Sku';
continue;
}
$_product = Mage::getModel('catalog/product')->loadByAttribute('sku',trim($val['sku']));
$_product->setCanSaveCustomOptions ( true );
$_product->setCanSaveBundleSelections ( true );
$_product->setAffectBundleProductSelections ( true );
$opt = $val['bundle_options'];
$optArr = explode(':', $opt);
//get the db write connection
$connection = Mage::getSingleton('core/resource')->getConnection('core_write');
$connection->beginTransaction();
foreach ( $optArr as $key1 => $val1 ) {
$valTemp = explode( '(', $val1 );
$title = trim($valTemp[0]);
//insert into catalog_product_bundle_option with parent product id and type
$__fields = array();
$__fields['parent_id'] = $_product->getId();
$__fields['required'] = 1;
$__fields['type'] = 'select';
$__fields['position'] = $key1+1;
$connection->insert($catalog_product_bundle_option, $__fields);
$opt_id = $connection->lastInsertId();
$connection->commit();
//inert into catalog_product_bundle_option_value with option id, store id, title
$__fields = array();
$__fields['option_id'] = $opt_id;
$__fields['store_id'] = 0;
$__fields['title'] = $title;
$connection->insert($catalog_product_bundle_option_value, $__fields);
$val_id = $connection->lastInsertId();
$connection->commit();
$skuStr = trim($valTemp[1]);
$skuStrTemp = explode( ')', $skuStr );
$skuStr = trim($skuStrTemp[0]);
$skuTemp = explode( '+', $skuStr );
$pos = 1;
foreach( $skuTemp as $key2 => $val2 ){
$id = Mage::getModel('catalog/product')->getResource()->getIdBySku($val2);
//insert into catalog_product_bundle_selection with option_id, parent product id, product id, position, is_default, selection_price_type, selection_price_value, selection_qty, selection_can_change_qty
$__fields = array();
$__fields['option_id'] = $opt_id;
$__fields['parent_product_id'] = $_product->getId();
$__fields['product_id'] = $id;
$__fields['position'] = $pos + 1;
$__fields['selection_price_type'] = 0;
$__fields['selection_price_value'] = 10;
$__fields['selection_qty'] = 1;
$__fields['selection_can_change_qty'] = 0;
$connection->insert($catalog_product_bundle_selection, $__fields);
$connection->commit();
$pos++;
}
}
//update product
$_product->save();
$_product = null;
}
my csv contains 2 columns one is sku and another is bundle options
example - sku - 12345678
bundle options - item01(ZIPLOCK18X24+ZIPLOCK16X20):item02(ZIPLOCK14X20+XEROMOCR84208X11)
in which item01 is the option title followed by simple products sku ZIPLOCK18X24, ZIPLOCK16X20 and : seperated incase of multiple options title.
I hope it may help someone.
