Magento : Issue Category name is auto renaming while saving - php

Question

i am importing the products with advance data flow profile and facing the weird problem while saving the category as i am passing the category name to my function as
Parent Category/Child category
The / sign between categories automatically create and assign the product to child category
it is working as expected but in my case the Parent Category name is renaming somehow i have checked that i am passing the right name to the function...
e.g. Semipreciuos gem stone beads/Stone type is saving as Semipreciuos gem stone bead/Stone type
The last s word is missing from the name
protected function _addCategories($categories,$desc='',$discountable,$store) {
$rootId = $store->getRootCategoryId ();
if (! $rootId) {
return array();
}
$rootPath = '1/' . $rootId;
if (empty ( $this->_categoryCache [$store->getId ()] )) {
$collection = Mage::getModel ( 'catalog/category' )->getCollection ()->setStore($store)->addAttributeToSelect ( 'name' );
$collection->getSelect ()->where ( "path like '" . $rootPath . "/%'" );
foreach ( $collection as $cat ) {
$pathArr = explode ( '/', $cat->getPath () );
$namePath = '';
for($i = 2, $l = sizeof ( $pathArr ); $i < $l; $i ++) {
$name = $collection->getItemById ( $pathArr [$i] )->getName ();
$namePath .= (empty ( $namePath ) ? '' : '/') . trim ( $name );
}
$cat->setNamePath ( $namePath );
}
$cache = array();
foreach ( $collection as $cat ) {
$cache [strtolower ( $cat->getNamePath () )] = $cat;
$cat->unsNamePath ();
}
$this->_categoryCache [$store->getId ()] = $cache;
}
$cache = & $this->_categoryCache [$store->getId ()];
$catIds = array();
foreach ( explode ( ',', $categories ) as $categoryPathStr ) {
$categoryPathStr = preg_replace ( '#s*/s*#', '/', trim ( $categoryPathStr ) );
if (! empty ( $cache [$categoryPathStr] )) {
$catIds [] = $cache [$categoryPathStr]->getId ();
continue;
}
$path = $rootPath;
$namePath = '';
foreach ( explode ( '/', $categoryPathStr ) as $catName ) {
$namePath .= (empty ( $namePath ) ? '' : '/') . strtolower ( $catName );
if (empty ( $cache [$namePath] )) {
$cat = Mage::getModel('catalog/category')->setStoreId($store->getId())->setPath ( $path )->setName ( $catName )->// comment out the following line if new categories should stay inactive
setIsActive(1)->setDescription($desc)->setData('discountable',$discountable)->save();
$cache [$namePath] = $cat;
}
$catId = $cache [$namePath]->getId ();
$path .= '/' . $catId;
}
##Assigning product to child category
/*$parentId = null;
$currentcat = Mage::getModel("catalog/category")->load($catId);
$parentId = $currentcat->getParentId();
if($parentId){
$catIds[] = $parentId;
}
*/
if ($catId) {
$catIds [] = $catId;
}
}
return join ( ',', $catIds );
}
Above is my category function for creating categories... any one has any idea what is going on..

It is not related to Magento, but rather to PHP & regular expression.
$categoryPathStr = preg_replace ( '#s*/s*#', '/', trim ( $categoryPathStr ) );
That line replaces "s*/s*" with "/", which is why you have your last s removed. I see no real reason for that preg_replace (?), so just remove that line, or replace it with
$categoryPathStr = trim ( $categoryPathStr );
so that leading/ending white spaces get removed.
