why all categories appear in one post, I just want to display the value category that matches the post.
public function edit(Post $post)
{
$categories = Category::all();
$tags = Tag::all();
return view('admin.post.edit', compact('post', 'categories', 'tags'));
}
<select id="category" name="categories[]" style="width: 100%" multiple>
#foreach($categories as $category)
<option
#foreach ($categories as $postCategory)
{{ $postCategory->id == $category->id ? 'selected' : '' }}
#endforeach
value="{{ $category->id }}">{{ $category->name }}</option>
#endforeach
</select>
<script>
$(document).ready(function () {
$("#category").select2({
placeholder: "Please Select"
});
});
</script>
Assuming $post will have a category_id you just need to check that field against the id of the current $category being iterated:
<select id="category" name="categories[]" style="width: 100%" multiple>
#foreach($categories as $category)
<option {{ $post->category_id == $category->id ? 'selected' : '' }}
value="{{ $category->id }}">{{ $category->name }}</option>
#endforeach
</select>

I have 2 selects on a page and i want to show the 2nd only when in the first select a specific option was chosen, is that possible in laravel? here the code:
<select class="form-select my-2" name="category_id">
<option disabled selected>Seleziona una categoria</option>
#foreach ($categories as $category)
<option value="{{ $category->id }}" #if ($category->id == old('category_id')) selected #endif>
{{ $category->name }}
</option>
#endforeach
</select>
<select class="form-select my-2" name="type_id">
<option disabled selected>Seleziona un tipo di sushi</option>
#foreach ($types as $type)
<option value="{{ $type->id }}" #if ($type->id == old('type_id')) selected #endif>
{{ $type->name }}
</option>
#endforeach
</select>
Using JQuery :
<script>
$('select[name="category_id"]').change(function (){
let categoryId = $(this).val();
if (categoryId == null)
{
$('select[name="type_id"]').hide();
}else{
$('select[name="type_id"]').hide();
}
});
</script>
how to make the old value selected in Laravel 8 blade with select input in edit form.... i tried this way but didn't work:
<select name="category" id="category" class=" #error('category') border-red-500 #enderror rounded-md shadow-sm mt-1 block w-full">
#foreach($categories as $category)
<option value="{{$category->id}}" {{ old('category', $category->id) ? 'selected' : '' }}>{{ $category->name }}</option>
#endforeach
</select>
and this is what inside controller:
public function edit(Product $product)
{
$categories = Category::all();
return view('dashboard.products.edit', compact('categories', 'product'));
}
I think your product should have a category_id so in the loop you need to check it also $product->category_id === $category->id.
#foreach($categories as $category)
<option value="{{$category->id}}" {{ old('category', $category->id) || $product->category_id === $category->id ? 'selected' : '' }}>{{ $category->name }}</option>
#endforeach
Based on the code in edit() method old() wont work. Because there is no old values since your code just return a view.If you need to use that function then you need to redirect with inputs like
return redirect()->back()->withInput();
I want to store multiple data to database because i have 2 select option with same name. i've following some tutorial from google and youtube but i still can't figured out how to do it.
Table structure:
id | nama_mapel | guru_id | kode_mapel | ki_kd_id |
I have view like this, there's 2 select option with same name:
<input type="text" name="nama_mapel[]">
<input type="text" name="kode_mapel[]">
<select type="text" name="guru_id[]">
<option value disable>Pilih Guru</option>
#foreach ($guru as $item)
<option value="{{ $item->id }}">{{ $item->nama_guru }}</option>
#endforeach
</select>
<select name="ki_kd_id[]">
<option value disable>Pilih Kompetensi Dasar</option>
#foreach ($komp_dasar as $kd)
<option value="{{ $kd->id }}">{{ $kd->kompetensi }}</option>
#endforeach
</select>
<select type="text" name="ki_kd_id[]">
<option value disable>Pilih Kompetensi Inti</option>
#foreach ($komp_inti as $ki)
<option value="{{ $ki->id }}">{{ $ki->kompetensi }}</option>
#endforeach
</select>
and this is my controller:
public function store(Request $request)
{
$nama_mapel = $request->nama_mapel;
$guru_id = $request->guru_id;
$kode_mapel = $request->kode_mapel;
$ki_kd_id = $request->ki_kd_id;
foreach ($nama_mapel as $row => $key){
$data= [
'nama_mapel' => $nama_mapel[$row],
'guru_id' => $guru_id[$row],
'kode_mapel' => $kode_mapel[$row],
'ki_kd_id' => $ki_kd_id[$row],
];
DB::table('mapel')->insert($data);
}
return redirect()->back();
}
Any help would be very appreciated, and sorry for my bad english.
I have found out how to do this.
For view it like this, only use array [] in ki_kd_id name. The reason is because the others is same. I have duplication for all fields except ki_kd_id.
<input type="text" name="nama_mapel">
<input type="text" name="kode_mapel">
<select type="text" name="guru_id">
<option value disable>Pilih Guru</option>
#foreach ($guru as $item)
<option value="{{ $item->id }}">{{ $item->nama_guru }}</option>
#endforeach
</select>
<select name="ki_kd_id[]">
<option value disable>Pilih Kompetensi Dasar</option>
#foreach ($komp_dasar as $kd)
<option value="{{ $kd->id }}">{{ $kd->kompetensi }}</option>
#endforeach
</select>
<select type="text" name="ki_kd_id[]">
<option value disable>Pilih Kompetensi Inti</option>
#foreach ($komp_inti as $ki)
<option value="{{ $ki->id }}">{{ $ki->kompetensi }}</option>
#endforeach
</select>
and for the controller, it will be like this:
public function store(Request $request)
{
foreach ($request->ki_kd_id as $value){
if ($value) {
DB::table('mapel')->insert([
'nama_mapel' => $request->nama_mapel,
'guru_id' => $request->guru_id,
'kode_mapel' => $request->kode_mapel,
'ki_kd_id' => $value,
]);
}
}
return redirect()->back();
}
Use foreach to loop the request based on how many ki_kd_id that the request have. and then for the value just use $value as representative of ki_kd_id
I want to retrieve database values in category name and i want to show default value in selection. This is my controller for my edit view.
I have a category_product table.
<div class="col-md-4">
<div class="form-group">
<label for="category">category</label>
<select class="form-control" name="category" id="category">
#foreach($categories as $category)
<option value="{{ $category->id }}" {{ $product->categories()->category_id == $category->id ? 'selected' : '' }}>{{ $category->name }}</option>
#endforeach
</select>
</div>
</div>
ProductController.php
public function edit(Product $product)
{
$categories = Category::all();
return view('Admin.products.edit', compact('product', 'categories'));
}
Product.php
public function categories()
{
return $this->belongsToMany(Category::class);
}
I get this error.
Undefined property: Illuminate\Database\Eloquent\Relations\BelongsToMany::$category_id
You need to add default value in the select tag above foreach() loop.
<div class="col-md-4">
<div class="form-group">
<label for="category">category</label>
<select class="form-control" name="category" id="category">
<option value="xyz">xyz</option> /* set default option value */
#foreach($categories as $category)
<option value="{{ $category->id }}" {{$category->id == $category->id ? 'selected' : '' }}>{{ $category->name }}</option>
#endforeach
</select>
</div>
</div>
If you want set category name selected then you need to match category in product collection. ( if you have catetory_id in product table )
<select class="form-control" name="category" id="category">
#foreach($categories as $category)
<option value="{{ $category->id }}" {{$product->catetory_id == $category->id ? 'selected' : '' }}>{{ $category->name }}</option>
#endforeach
</select>
I want to show the old select value in this select field when I want to edit. How can I show my old value in these fields?
https://github.com/shakibzaman/book-library-laravel
you can show my GitHub repo-
Here is my rules edit page:
<div class="form-group {{ $errors->has('name') ? 'has-error' : '' }}">
<label for="chap_id">{{ trans('cruds.chapters.title_singular') }}*</label>
<select name="chap_id" id="chap_id" class="form-control select2">
#foreach($chapters as $id => $chapter)
<option value="{{ $id }}">{{ $chapter }}</option>
#endforeach
</select>
#if($errors->has('name'))
<em class="invalid-feedback">
{{ $errors->first('name') }}
</em>
#endif
<p class="helper-block">
{{ trans('cruds.permission.fields.title_helper') }}
</p>
</div>
editController
public function edit($id)
{
if (!Gate::allows('users_manage')) {
return abort(401);
}
$rule = Rule::find($id);
$chapters = Chapter::all()->pluck('name', 'id')->prepend(trans('global.pleaseSelect'), '');
return view('admin.rules.edit', compact('rule', 'chapters'));
}
You can use the old() function to get the old value of a field. This function requires one input and that is the name of the field: old('chap_id').
You could use this one:
#foreach($chapters as $id => $chapter)
#if(null !== old('chap_id') && old('chap_id') === $id)
<option value="{{ $id }}" selected>{{ $chapter }}</option>
#else
<option value="{{ $id }}">{{ $chapter }}</option>
#endif
#endforeach
Or the shorter one:
#foreach($chapters as $id => $chapter)
<option value="{{ $id }}" {{ old('chap_id') === $id ? 'selected' : '' }}>{{ $chapter }}</option>
#endforeach
