blade view

@foreach($locations as $location)
<div>
    <form wire:submit.prevent="updateLocation('{{ $location->locationID }}')">
        <div>
            <label for="unitNo">Unit No</label>
            <input type="text" placeholder="{{ $location->unitNo }}" wire:model="unitNo">

            <label for="street">Street</label>
            <input type="text" placeholder="{{ $location->street }}" wire:model="street">

            <label for="city">City</label>
            <input type="text" placeholder="{{ $location->city }}" wire:model="city">

            <label for="state">State</label>
            <input type="text" placeholder="{{ $location->state }}" wire:model="state">

            <label for="postCode">Post Code</label>
            <input type="text" placeholder="{{ $location->postCode }}" wire:model="postCode">
        </div>
        <button type="submit" class="btn border-black">Update</button>
    </form>
</div>
@endforeach

HTML for better understandingCould you guys please help me troubleshoot my code, i am trying to make a form where it has placeholder of saved locations based on the userID and when i type in the placeholder and click the button, it could update into database based on the locationID of the location.

What should i do to make it work? Thank you.

Answer 1

wire:submit.prevent="updateLocation('{{ $location->locationID }}')" here you're passing locationID but your function public function updateLocation() doesn't have $locationID for further control.

Change your function like this public function updateLocation($locationID)

Also change this $location = Location::find($this->locationID); to $location = Location::findOrFail($locationID);
