Laravel not validating array input

Question

I'm trying to validate some input array fields in Laravel. My application reports back the field is required, even though it has been filled out.

The validation code I have is:

$this->validate($request, [
        'first_name'        => 'required',
        'last_name'         => 'required',
        'telephone'         => 'required',
        'email'             => 'unique:contacts,email,' . $request->id,
        'address'           => 'required',
        'address.0.address_line_1'         => 'required',
    ]);

The full posted array is:

Array
(
[id] => 1
[_token] => xxx
[first_name] => Joe
[last_name] => Bloggs
[contact_name] => Joe Bloggs
[telephone] => 077
[email] => joe@test.com
[address] => Array
    (
        [0] => Array
            (
                ['address_line_1'] => sss
                ['address_line_2'] => 
                ['city'] => 
                ['county'] => 
                ['postcode'] => 
                ['property_type'] => site
            )

    )

)

My input fields are constructed like so:

address[0]['address_line_1']

I'm getting the validation message error:

The address.0.address line 1 field is required.

Anyone know what's wrong here?

It's not a duplicate - i've tried what they said in the same thread, but it doesn't work for me. — V4n1ll4, Mar 05 '22 at 17:14
What if you remove your requirement of `address`? It might conflict. — Marwelln, Mar 05 '22 at 19:54

That's because you don't have any address_line_1 or address_line_2 in your array validation but you have posted those two elements.

You only have address.0.address_line_1 and there's no address.0.address_line_1 inside your posted data.

The elements of your array validation should be the same with what you posted. In your case, you can remove address.0.address_line_1 and add 2 more elements of your array validation.

'address_line_1' => 'required',
'address_line_2' => 'required',

The updated answer :

'address' => 'required|array',
'address.*' => 'required|array',
'address.*.address_line_1' => 'required|string',

But my form fields look like: address[0]['address_line_1'] – V4n1ll4 Mar 05 '22 at 17:15
Try to change `'address.0.address_line_1'` with `'address.*.address_line_1'` – zaidysf Mar 05 '22 at 17:17
Please change the description of your posted array to posted address array because I thought that it was your full posted array. – zaidysf Mar 05 '22 at 17:22
tried this already, but get the same... – V4n1ll4 Mar 05 '22 at 17:24
I've just posted the full array which is returned – V4n1ll4 Mar 05 '22 at 17:26
what the error message when you try with that : 'address_line_1' => 'required', ? And maybe try like this : 'address.address_line_1' => 'required', – Ondrelat Mar 05 '22 at 17:28
@V4n1ll4 try to remove `'address.0.address_line_1' => 'required',` and add more elements like my updated answer – zaidysf Mar 05 '22 at 17:31
Still getting the same... – V4n1ll4 Mar 05 '22 at 18:21
Try again my updated answer – zaidysf Mar 05 '22 at 18:33

Just replace your validator with this

$this->validate($request, [
   'first_name' => 'required',
   'last_name'  => 'required',
   'telephone'  => 'required',
   'email' => 'unique:contacts,email,' . $request->id,
   'address' => 'required',
    'address.*' => 'required',
    'address.*.address_line_1' => 'required',
]);

Thanks, but it's still failing validation saying "The address.0.address_line_1 field is required." even though it's filled. – V4n1ll4 Mar 05 '22 at 19:03
I'm thinking this could possibly b a bug with Laravel version 5.2.45 – V4n1ll4 Mar 05 '22 at 19:06

I managed to figure out what was causing the issue...it was actually to do with the form input field names.

I removed the single quotes from the input names and it worked!

I changed:

<input type="text" class="form-control" name="address[0]['address_line_1']">

To, this:

<input type="text" class="form-control" name="address[0][address_line_1]">

And it worked! Hope it helps someone else.
