I am using baum to get nested list of categories. I have a case where I only want to get a child of few parent id. I have used static function getNestedList("name", null, " ") which gives me all categories nested list separated by space. I want the same response but only for few parent categories.
I tried below code to get my list with where clause but it only works with the first result. I have multiple parent_id and I need the each child listed in an array with space operator.
$node = Category::where('name', '=', 'Some category I do not want to see.')->first();
$root = Category::where('name', '=', 'Old boooks')->first();
var_dump($root->descendantsAndSelf()->withoutNode($node)->get());
QUESTION UPDATE
The issue I was facing to get descendants and self categories list using Baum was just because of wrong entry in my database. I am sorry for that. Now, I am getting my category list using descendantsAndSelf() but the issue is how to created the nested list with $seperator ?
I tried to toHierarchy() but it only return nested collection. I did not found any function which provides nested list like the function getNestedList("text", null, " ");. Please help me on this.
UPDATED ANSWER
As per my updated question, Below is my answer what I actually want to do.
To get list of Descendants with parent I have used below function.
public function getSubcategory($id) {
$node = $this->where('id', $id)->with('children')->first();
$descendant = $node->getDescendantsAndSelf()->toArray();
return $this->CreateNestedList("text", $descendant, null, "-");
}
And to create nested loop I have used the same logic of the function
getNestedList(). I have created new function inside my model file as below.
public function CreateNestedList($column, $data, $key = null, $seperator = ' ') {
$key = $key ?: $this->getKeyName();
$depthColumn = $this->getDepthColumnName();
return array_combine(array_map(function($node) use($key) {
return $node[$key];
}, $data), array_map(function($node) use($seperator, $depthColumn, $column) {
return str_repeat($seperator, $node[$depthColumn]) . $node[$column];
}, $data));
}
