Laravel Eloquent whereHas() Condition with Example

In this post, you will learn how to implement Laravel Eloquent whereHas() condition in this method you can able to display the existing relations of a specific record. For example, if you have a ticket and that ticket has a conversation and you want to update a specific conversation. But before doing it you need to ensure that the conversation you want to update belongs to a ticket.

So in my below example, you will see how we use the Laravel whereHas() condition.

$ticketId = 1;
$convoId = 1;


$ticket = Ticket::where('id', $ticketId)->with('conversations', function($query) use($convoId) {
    $query->where('id', $convoId);
})->whereHas('conversations', function (Builder $query) use($convoId){
    $query->where('id', $convoId);
})->firstOrFail();

$convo = $ticket->conversations->first();

$convo->message = 'updated convo';
$convo->save();

As you can see I have condition first with $ticketId and using the with() method of eloquent then apply the whereHas() method so that I only display a specific conversation with $convoId.

That's pretty much it. I hope it helps. Thank you for reading :)
