I'm studying keyword search.
I successed single keyword search and now I'm trying to make multiple one.
as Half-width space keyword split.
I use this Middlewarefrom this website
https://qiita.com/logue/items/64c4b5545f76ef17de70
When I dd() . I can see keyword split are good.
but when I search function runs There is no sql sentence appear
and I can display empty result page.
Could you teach me correct code please?
Controller
public function order_adv()
{
$keyword = request('search_adv');
if(!empty($keywords)) {
foreach ($keywords as $keyword) {
$products = Product::when('w_m','like','%'.$keyword.'%');
}
}
return view('products.result_adv' , compact('products'))
->with('i', (request()->input('page', 1) - 1) * 5);
}
WEB.php
Route::get('products/search_adv', [ProductController::class, 'search_adv'])->name('search_adv');
Route::post('products/search_adv', [ProductController::class, 'order_adv'])->name('products.search_adv')->middleware('keyword');
You can use where call back method
public function order_adv()
{
$keywords =explode(' ',request('search_adv'));
$products = Product::when(count((array)$keywords),function($query)use($keywords){
$query->where(function($query)use($keywords){
foreach ($keywords as $keyword) {
$query->orWhere('w_m','like','%'.$keyword.'%');
}
});
})->get();
return view('products.result_adv' , compact('products'))
->with('i', (request()->input('page', 1) - 1) * 5);
}
$keywords = request('search_adv');
if (count($keywords) > 0) {
$products = Product::where(function($query)use($keywords) {
foreach ($keywords as $keyword) {
$query->orWhere('w_m', 'LIKE', "%{$keyword}%");
}
})->get();
}
In your case use where Clauses,
https://laravel.com/docs/8.x/queries#where-clauses
use when in condition statement,

I want to remove where clauses in some conditions:
$q = Thread::with('comments')->take(10);
if(strlen($input) < 4){
$result = $q->where('title', '~', "^$input$")->get();
if($result->isNotEmpty()){
return $result;
}
// if was empty:
}
// How to clean the where clause from the above here? because it affect the query below:
$result = $q->where('title', 'like', "%$input%")->get();
The problem is the first where clause affects the second one if the data was empty, How can i remove existing where clauses when needed ? also the newQuery() is not working in my case.
Note that i'm using two seperate statement in postgres ~ and 'like'
Something like reorder() for where clauses
Yes there is a way to do it
$q = Thread::with('comments')->take(10);
if(strlen($input) < 4){
$result = $q->where('title', '~', "^$input$")->get();
if($result->isNotEmpty()){
return $results;
}
}
// getQuery() is a query builder method that contains all the groupings, selects, orders, wheres, joins etc for the query that you are accessing or trying to build.
$q->getQuery()->wheres= [];
$result = $q->where('title', 'like', "%$input%")->get();
Use Conditional Clauses
$threads = Thread::with('comments')->when(strlen($input) < 4, function ($query) use ($input) {
return $query->where('title', '~', "^$input$");
}, function ($query) use ($input) {
return $query->where('title', 'like', "%$input%");
})->take(10)->get();
https://laravel.com/docs/8.x/queries#conditional-clauses
If you want to give it a second change I would write that logic like this. Comments are loaded only if they are needed.
if (strlen($input) < 4) {
$threads = Thread::where('title', '~', "^$input$")->take(10)->get();
if ($threads->isNotEmpty()) {
return $threads->load('comments');
}
}
return Thread::with('comments')->where('title', 'like', "%$input%")->take(10)->get();
if you cloning before add where
it works the same as deleting where
...
if(strlen($input) < 4){
$result = (clone $q)->where('title', '~', "^$input$")->get();
if($result->isNotEmpty()){
return $results;
}
}
$result = $q->where('title', 'like', "%$input%")->get();
...
Goodmorning
I'm trying to make a filter with multiple variables for example I want to filter my products on category (for example 'fruit') and then I want to filter on tag (for example 'sale') so as a result I get all my fruits that are on sale. I managed to write seperate filters in laravel for both category and tag, but if I leave them both active in my productsController they go against eachother. I think I have to write one function with if/else-statement but I don't know where to start. Can somebody help me with this please?
These are my functions in my productsController:
public function productsPerTag($id){
$tags = Tag::all();
$products = Product::with(['category','tag','photo'])->where(['tag_id','category_id'] ,'=', $id)->get();
return view('admin.products.index',compact('products','tags'));
}
public function productsPerCategory($id){
$categories = Category::all(); //om het speciefieke id op te vangen heb ik alle categories nodig
$products = Product::with(['category','tag','photo'])->where('category_id', '=', $id)->get();
return view('admin.products.index',compact('products','categories'));
}
These are my routes in web.php. I guess this will also have to change:
Route::get('admin/products/tag/{id}','AdminProductsController#productsPerTag')->name('admin.productsPerTag');
Route::get('admin/products/category/{id}','AdminProductsController#productsPerCategory')->name('admin.productsPerCategory');
For filter both
change your URL like
Route::get('admin/products/tag/{tag_id?}/{category_id?}','AdminProductsController#productsPerTag')->name('admin.productsPerTag');
Make your function into the controller like
public function productsPerTag($tagId = null, $categoryId = null){
$tags = Tag::all();
$categories = Category::all();
$query = Product::with(['category','tag','photo']);
if ($tagId) {
$query->where(['tag_id'] ,'=', $tagId);
}
if ($tagId) {
$query->where(['category_id'] ,'=', $categoryId);
}
$products = $query->get();
return view('admin.products.index',compact('products','tags', 'categories'));
}
You are trying to filter in your query but you pass only 1 parameter to your controller, which is not working.
1) You need to add your filters as query params in the URL, so your url will look like:
admin/products/tag/1?category_id=2
Query parameters are NOT to be put in the web.php. You use them like above when you use the URL and are optional.
2) Change your controller to accept filters:
public function productsPerTag(Request $request)
{
$categoryId = $request->input('category_id', '');
$tags = Tag::all();
$products = Product::with(['category', 'tag', 'photo'])
->where('tag_id', '=', $request->route()->parameter('id'))
->when((! empty($categoryId)), function (Builder $q) use ($categoryId) {
return $q->where('category_id', '=', $categoryId);
})
->get();
return view('admin.products.index', compact('products', 'tags'));
}
Keep in mind that while {id} is a $request->route()->parameter('id')
the query parameters are handled as $request->input('category_id') to retrieve them in controller.
Hope It will give you all you expected outcome if any modification needed let me know:
public function productList($tag_id = null , $category_id = null){
$tags = Tag::all();
$categories = Category::all();
if($tag_id && $category_id) {
$products = Product::with(['category','tag','photo'])
->where('tag_id' , $tag_id)
->where('category_id' , $category_id)
->get();
} elseif($tag_id && !$category_id) {
$products = Product::with(['category','tag','photo'])
->where('tag_id' , $tag_id)
->get();
} elseif($category_id && !$tag_id) {
$products = Product::with(['category','tag','photo'])
->where('category_id' , $category_id)
->get();
} elseif(!$category_id && !$tag_id) {
$products = Product::with(['category','tag','photo'])
->get();
}
return view('admin.products.index',compact(['products','tags','products']));
}
Route:
Route::get('admin/products/tag/{tag_id?}/{category_id?}','AdminProductsController#productsPerTag')->name('admin.productsPerTag');
I am working on laravel 5.5 project
i have four tables as following:-
1- Subject model (has following relations)
public function types()
{
return $this->belongsToMany('App\Types');
}
public function areas()
{
return $this->belongsToMany('App\Area');
}
public function articles()
{
return $this->hasMany('App\Article');
}
2- Area and Types has many to many relation with Subject model
public function subjects()
{
return $this->belongsToMany('App\Subjects');
}
3- Article has 1 to many relation with Subject
public function subjects()
{
return $this->belongsTo('App\Subjects');
}
The below controller will search for subject by keyword, select type or area and return value as json using toJson() and return results to view:-
public function search(Request $request)
{
//start search//
$get_Subjects = new Subject();
$get_Subjects = $get_Subjects ->newQuery();
if($request->term != '')
{
$get_Subjects->with('articles')->whereHas('articles', function ($query) use ($request){
$query->where('title', 'LIKE', '% '.$request->term.' %')
->orwhere('abstract', 'LIKE', '% '.$request->term.' %')
->orwhere('fullCitation', 'LIKE', '% '.$request->term.' %');
})
->where(function($query) use ($request){
$query->where('name', 'LIKE', '%'.$request->term.'%');
});
}if($request->area != '28')
{
// search for the selected area
$get_Subjects->with('areas')->whereHas('areas', function($query) use ($request){
$query->where('area_id', $request->area);
});
}
if($request->type!= '36')
{
// search for the selected types
$get_Subjects->with('types')->whereHas('types', function($query) use ($request){
$query->where('type_id', $request->type);
});
}
$subjects = $get_Subjects->tojson();
return View::make('public.search', compact('subjects'));
}
the issue is when i search by keyword the returned json only include related articles, and if i search by area i only get related areas()
while if i did not use json and access variable from blade i can access all related models even though it is the same query
i tried to use load() but it did not work
any help will be valuable
============Update===========
i tried using load() as follow
$subjects= $get_subjects->get();
$subjects= $subjects->load('articles', 'areas', 'types')->tojson();
when search by keyword, the json does have related relations
but they are empty
when search by area or type, the json does have related relation
which mean if i search in the subject table only which is the 1st case i wont get related model with it
please need your help
Have you tried adding the ->get() method before the ->toJson() method?
$subjects = $get_Subjects->get()->toJson();
get() will run the query and return models. toJson() should then work as you expect.
Update
I would write your code like this to start with. (I haven't tested this).
It seems like you are using the whereHas the wrong way. The subject table should have the area_id and type_id fields, so whereHas isn't needed... this might not be the case, but it seems like it should be based on the info you provided.
public function search(Request $request)
{
$get_Subjects = new Subject();
$get_Subjects = $get_Subjects ->newQuery();
$with = [];
if($request->term != '') {
$with[] = 'articles';
$subjects = $get_Subjects->whereHas('articles', function ($query) use ($request){
$query->where('title', 'LIKE', '% '.$request->term.' %')
->orwhere('abstract', 'LIKE', '% '.$request->term.' %')
->orwhere('fullCitation', 'LIKE', '% '.$request->term.' %');
})
->where('name', 'LIKE', '%'.$request->term.'%');
}
if($request->area != '28') {
$with[] = 'areas';
$get_Subjects->where('area_id', $request->area);
}
if($request->type!= '36') {
$with[] = 'types';
$get_Subjects->where('type_id', $request->type);
}
$subjects = $get_Subjects->with($with)->get()->toJson();
return View::make('public.search', compact('subjects'));
}
I have a search query like this:
$data = User::where('first_name', 'like', '%'.$query.'%')
->orWhere('last_name', 'like', '%'.$query.'%')
->get();
Now, I have many models, each with different column names. Instead of defining a search() function into every controller, I want to do this:
// User
public static function searchableFields()
{
return ['first_name', 'last_name'];
}
// Some other model
public static function searchableFields()
{
return ['name', 'description'];
}
And put the search logic in a shared controller, something like this:
$data = $classname::
where($classname::searchableFields(), 'like', '%'.$query.'%')
->get();
How can I achieve this?
Thanks a lot.
You can loop over the fields and add them to your Eloquent query one by one.
$data = $classname::where(function ($query) use ($classname) {
foreach ($classname::searchableFields() as $field)
$query->orWhere($field, 'like', '%' . $query . '%');
})->get();
I would use scope for that.
You can create base model that all the models should extend (and this model should extend Eloquent model) and in this model you should add such method:
public function scopeMatchingSearch($query, $string)
{
$query->where(function($q) use ($string) {
foreach (static::searchableFields() as $field) {
$q->orWhere($field, 'LIKE', '%'.$string.'%');
}
});
}
Now you can make a search like this:
$data = User::matchingSearch($query)->get();
Just to avoid confusion - $query parameter passed to matchingSearch becomes $string parameter in this method.
You can try something like this.
// Controller
function getIndex(Request $request)
{
$this->data['users'] = User::orderBy('first_name','asc')->get();
if ($request->has('keyword')) {
$results = User::search($request->keyword);
$this->data['users'] = collect([$results])->collapse()->sortBy('first_name');
}
}
// Model
function search($keyword)
{
$results = [];
$search_list = ['first_name','last_name'];
foreach ($search_list as $value)
{
$search_data = User::where($value,'LIKE','%'.$keyword.'%')->get();
foreach ($search_data as $search_value) {
$exist = 0;
if (count($results)) {
foreach ($results as $v) {
if ($search_value->id == $v->id) {
$exist++;
}
}
if ($exist == 0) {
$results[] = $search_value;
}
} else{
$results[] = $search_value;
}
}
}
return $results;
}
stuck on a form that allows the user to enter a value into a choice of two fields. I can query the database using one field but want to add more range to database queries. With the following code below when i try to access the page to query it just shows me a white screen.
public function index()
{
$data = $request->all();
if(!empty($data['pstoreNum']))
{
$pstoreNum = $data['pstoreNum'];
$result = DB::table('perfumes')->where('StoreNumber','=',$pstoreNum)
->get();
return view('perfumes',compact('result'));
}
else if(!empty($data['pweekNum']))
{
$pweekNum = $data['pweekNum'];
$result = DB::table('perfumes')->where('WeekNumber','=',$pweekNum)
->get();
return view('perfumes',compact('result'));
}
}
My routes file simple calls the index function. Any help would be appreciated.
You can add query functions within your query like so
public function index(Request $request)
{
$data = $request->all();
$result = \DB::table('perfumes')->where(function($query) use ($data) {
if(!empty($data['pstoreNum'])) {
$query->where('StoreNumber', '=', $data['pstoreNum']);
}
if(!empty($data['pweekNum'])) {
$query->where('WeekNumber', '=', $data['pweekNum']);
}
})->get();
return view('perfumes',compact('result'));
}
You can then use the one query and add multiple wheres on various conditions.
