I am using function of Laravel eloquent model.
Here is the code:-
$keywords = ['name1', 'name2', 'name3'];
$authors = App\Author::with(['books' => function ($query) use ($keywords) {
// $query->where('name', 'like', '%name2%');
foreach ($keywords as $name) {
$query->orWhere('name', 'like', "%$name%");
}
}])->get();
I am trying to return all authors along with books where the name of the book matches the values in a given array of keywords. I have used foreach loop to go through multiple orwhere() like conditions, but the condition does not seem to be working. However, the commented out statement is working fine for me.

I have models 'Case' and 'Type' in many to many relation. 'Case' belongs to a 'Type'. Now I am trying to implement search and filter in my case index. I have already included the search in the query builder so that the keywords match multiple columns and also columns in related table. Now I am trying to incorportae a filter also. But when I am including that filter in query builder, it is not working. Including either search or filter is working but including both together is not.
Here is my code to include the search in query builder:
$key = $this->search;
$cases = Landcase::query()->orderBy('created_at', 'DESC');
$cases
->where('number', 'like', '%'.$this->search.'%')
->orWhere('title', 'like', '%'.$this->search.'%')
->orWhereHas('type', function ($query) use ($key) {
$query->where('name', 'like', $key.'%');
});
This much is perfectly working. I can search in title, number and type's name. Now here is the additional code to include the filter with type id(s) so that only specific type's cases will be shown and the search will work on those only.
if($this->selected_types){
$ids= $this->selected_types;
$cases->whereHas('type', function ($query) use ($ids){
$query->whereIn('id', $ids);
});
}
this block is not affecting the collection. But if I comment out the first block, this works. How can I incorporate it to my existing query builder block?
You have several OR in your where clauses so adding the last part makes it something like:
WHERE … OR … OR (… AND …)
What you need is to group your orWheres:
$cases->where(function ($query) {
$query
->where('number', 'like', '%'.$this->search.'%')
->orWhere('title', 'like', '%'.$this->search.'%')
->orWhereHas('type', function ($query) use ($key) {
$query->where('name', 'like', $key.'%');
});
});

I am new to laravel,
I need to create a query for the db,
$query = Deal::query();
I want to use the wherehas operator.
this is my code that is worked.
else if ($group_by == 'precedence') {
if($get_deals_for == 'noprecedence'){
$get_deals_for = 0;
}
$precedenceStatus = $get_deals_for;
$query-> where('precedence', '=', $precedenceStatus);
// \Log::info('The request precedence: '.$precedenceStatus);
}
I want to add this code also to the query
if($person) {
$query->whereHas('personnel', function ($subQuery) use ($person) {
$subQuery->where('id', '=', $person);
});
}
So I need to change the first code?
how I can convert the first code to wherehas?
the first code is from table called deal, the second section is from realtionship called personnel.
the second section worked in other places in the code, I just need to fix the first section and not understand what to write in the use
I try this and get error on the last }
else if ($group_by == 'precedence') {
if($get_deals_for == 'noprecedence'){
$get_deals_for = 0;
}
$precedenceStatus = $get_deals_for;
$query-> where('precedence', '=', $precedenceStatus)
-> when ($person, function($query) use($person) {
$query->whereHas('personnel', function ($query) use ($person) {
$query->where('id', '=', $person);
});
})
}
There is a method you can use called when(, so that you can have cleaner code. The first parameter if true will execute your conditional statement.
https://laravel.com/docs/9.x/queries#conditional-clauses
$result = $query
->where('precedence', '=', $precedenceStatus)
->when($person, function ($query) use ($person) {
$query->whereHas('personnel', fn ($q) => $q->where('id', '=', $person));
})
->get();
You should also be able to clean up your precedence code prior to that using when( to make the entire thing a bit cleaner.
Querying to DB is so easy in laravel you just need to what you want what query you want execute after that you just have to replace it with laravel helpers.Or you can write the raw query if you cant understand which function to use.
using,DB::raw('write your sql query').
Now Most of the time whereHad is used to filter the data of the particular model.
Prefer this link,[Laravel official doc for queries][1] like if you have 1 to m relation ship so u can retrive many object from one part or one part from many object.like i want to filter many comments done by a user,then i will right like this.
$comments = Comment::whereHas('user', function (Builder $query) {
$query->where('content', 'like', 'title%');
})->get();
$comments = Here will be the model which you want to retrive::whereHas('relationship name', function (Builder $query) {
$query->where('content', 'like', 'title%');
})->get();
you can also write whereHas inside whereHas.

Wondering if there is a way to use closure on a relationship in order to filter the whole line if there isn't a value which corresponds?
Example code:
foreach ($paiementMethods as $value) {
$giftCards = GiftCard::with(['userEntered', 'userEmployee', 'client', 'payement', 'payement.payementMethods' => function($query) use ($value)
{
$query->where('id', $value);
}])
->where('date','>=', $dateStart)
->where('date','<=', $dateEnd)
->orderBy('updated_at', 'desc')->get();
$giftCardsCollection = $giftCardsCollection->merge($giftCards);
}
}
In this example, if $query->where doesn't find a row for the payement.payementMethods which matches the $value, I want the giftCard to return null. The result I get is the giftCard with only the relation on payement.payementMethods being empty.
My other solution would be to query the giftCard and after that checking the $value to see if I have to include the giftCard in the collection or not.
Best regards
I think using whereHas, it can be solved
$giftCards = GiftCard::with(['userEntered', 'userEmployee', 'client', 'payement', 'payement.payementMethods'])
->whereHas( 'payement.payementMethods', function($query) use ($paiementMethods) {
$query->whereIn('id', $paiementMethods);
})
->where('date','>=', $dateStart)
->where('date','<=', $dateEnd)
->orderBy('updated_at', 'desc')
->get();
I am trying to get the news of a writer according to date passed. I have written function so far:
public static function getNewsByAuthorByDate($id, $year, $limit = 1){
return User::where('id', $id)->has('news')
->with(['news' => function($q) use(&$limit, &$year) {
$q->where('created_at', 'like', '%' . $year . '%')->latest()->limit($limit);
}])
->first();
}
But the news[] is null. Is it possible to get writer news according to date or do I have to try another way?
you can use whereYear
public static function getNewsByAuthorByDate($id, $year, $limit = 1){
return User::where('id', $id)->has('news')
->with(['news' => function($q) use(&$limit, &$year) {
$q->whereYear('created_at',$year)->latest()->limit($limit);
}])
->first();
}
and to use limit with eager loading you should use the package eloquent-eager-limit
According to the documentation:
The limit and take query builder methods may not be used when constraining eager loads.
Also, You don't need to use has method, the news would be empty if the user has no news:
return User::with(['news' => function($q) use($year) {
$q->whereYear('created_at', $year)->latest();
}])
->find($id);
My Code
$videos = ExamVideo::with([
'user' => function ($query) use ($request) {
$query->where('user_name', 'like', '%'.$request->search.'%');
}
])->where('is_marked','=', 0)->get();
return $videos;
I want to get only those videos where is_marked is zero & it's relation user_name match my search result.
But I get all the videos which marked is zero.
The with method is only for eager loading and not used to filter your records.
You can accomplish what you want with the whereHas method which will perform a query on the relation:
$videos = ExamVideo::whereHas('user', function ($query) use ($request) {
$query->where('user_name', 'like', "%{$request->search}%");
})->where('is_marked', false)->get();
