How can i set this
public $foo = [" "," "," "," "," "," "," "," "," "," "];
// the updated* method follows your variable name and is camel-cased, in this sample, 'foo'
public function updatedFoo()
{
// your code you want to execute
}
So in your view you will have to wire that property to a model:
@foreach($foo as $i => $val)
<input type="text" wire:model="foo.{{$i}}">
@endforeach
now whenever you type anything in one of those input fields you will get the value and you can also get the index of the element in the array:
public function updatedFoo($newVal, $key)
{
// this is just for debugging, you ofcourse would want to do something with the value.
dd($newVal, $key);
}
@Nakov can you validate newVal and send error back?
@Abin you can try. I haven't used that.
public function updatedFoo($newVal, $key)
{
// set the value first
$this->validate(); // this should handle validation if you have $rules and display the error if any
}
@Nakov I am very new so I dont actually understand it.
public function updatingTitles($name, $value){ if( Str::length($name) > 0){ DB::table($this->table_name) ->where('id', (int)$value) ->update(['title' => $name,]); }else { $name = $this->titles[$value]; } $this->titles[$value] = $name; }
This prevents the empty data being saved in the table but the field retains the empty value and no error message.
@Abin Take a read here: https://laravel-livewire.com/docs/2.x/input-validation
I wouldn't perform database updates within the update function.. because that one will be triggered each time a field has a new value..
