نحوه استفاده از تابع بازگشتی در php خام
سلام دوستان وقت بخیر ،
سئوال من اینه که چطور کد های تابع بازگشتی در لاراول رو به php خام تبدیل کنم؟! کد های لاراول رو میزارم :
ابتدا دسته بندی های مادر رو سلکت کردیم :
public function index()
{
$categories = Category::where('parent' , 0)->latest()->paginate(10);
return view('panel.category.index' , compact("categories"));
}و در صفحه مربوطه دیتا رو دریافت کردیم و
به همراه include مقادیر رو پاس میدیم
@include('panel.category.categories_group' , ['categories' => $categories])و در این صفحه تمام دسته بندی ها و زیر دسته ها نمایش داده میشه
<ul class="list-group list-group-flush">
@foreach($categories as $cate)
<li class="list-group-item">
<div class="d-flex">
<span>{{ $cate->name }}</span>
<div class="actions mr-2">
<form action="{{ route('admin.categories.destroy', $cate->id) }}" id="cate-{{ $cate->id }}-delete" method="POST">
@csrf
@method('delete')
</form>
<a href="#" onclick="event.preventDefault(); document.getElementById('cate-{{ $cate->id }}-delete').submit()" class="badge badge-danger">حذف</a>
<a href="{{ route('admin.categories.edit' , $cate->id) }}" class="badge badge-primary">ویرایش</a>
<a href="{{ route('admin.categories.create') }}?parent={{ $cate->id }}" class="badge badge-warning">ثبت زیر دسته</a>
</div>
</div>
@if($cate->child->count())
@include('panel.category.categories_group' , [ 'categories' => $cate->child])
@endif
</li>
@endforeach
</ul>گزینش سوالات

جناب پارسیان ممنونم ازتون.
در رابطه با کد زیر اگر ممکنه راهنمایی کنید...
این کد داخل یک لوپ بی نهایت قرار میگیره و فقط دسته بندی اول رو نمایش میده (شاید چون شی دوباره ساخته میشه!)
کد به این صورت هست :
کلاس Category
public function get(int $id = null)
{
if(! isset($id)){
$stmt = $this->pdo_panel->prepare("SELECT * FROM {$this->table} where parent IS NULL ");
if ($stmt->execute()) {
if ($stmt->rowCount() >= 1) {
return $category = $stmt->fetchAll(PDO::FETCH_OBJ);
}
}
}else{
$stmt = $this->pdo_panel->prepare("SELECT * FROM {$this->table} where parent = :id ");
$stmt->bindParam(":id", $id);
if ($stmt->execute()) {
if ($stmt->rowCount() >= 1) {
return $category = $stmt->fetchAll(PDO::FETCH_OBJ);
}
}
}
}
public function count($id)
{
$stmt = $this->pdo_panel->prepare("SELECT * FROM {$this->table} where parent = :id ");
$stmt->bindParam(":id", $id);
if ($stmt->execute()) {
if ($stmt->rowCount() >= 1) {
return $stmt->rowCount();
}
}
}و کد های تابع بازگشتی
<?php
foreach ($category->get() as $item) : ?>
<tr>
<?php var_dump($item->id); ?>
<td class="wrap_table"></td>
<td class="wrapper_table_product"><?= $item->id ?></td>
<td class="wrapper_table_product"><?= $item->name ?>
</td>
<td class="wrapper_table_product"><a href="edit-product.php?edit-product=<?= $item->name ?>"><i
class="material-icons">edit</i></a></td>
<td class="wrapper_table_product "><a class="delete delete-product" data-id="<?= $item->name ?>"><i
class="material-icons">delete</i></a>
</td>
</tr>
<?php
if ($category->count($item->id)) {
$category->get($item->id);
include "category-child.php";
}
?>
<?php endforeach; ?>

سلام دوباره فکر کنم مشکل از اخرش باشه!
if ($category->count($item->id)>0) {
$category->get($item->id);
include "category-child.php";
}اولین تابع رو هم میتونی اینطوری بهینه کنی
public function get(int $id = null)
{
$stmt = $this->pdo_panel->prepare("SELECT * FROM {$this->table} where parent = :id ");
$stmt->bindParam(":id", $id);
if ($stmt->execute()) {
if ($stmt->rowCount() >= 1) {
return $category = $stmt->fetchAll(PDO::FETCH_OBJ);
}
}
}
