Laravel - Undefined index - php

Question

What I am trying to do is to add an expense and a vendor in the same time knowing that the relation between expenses table and vendors table is a one to many relation ..
A vendor can have vendor_contacts which is a table that have a one to many relation with vendors table ..
This is my code :
if (isset($data['vendor'])) {
$canSaveVendor = false;
$vendorPublicId = array_get($data, 'vendor.public_id') ?: array_get($data, 'vendor.id');
if (empty($vendorPublicId) || $vendorPublicId == '-1') {
$canSaveVendor = Auth::user()->can('create', ENTITY_VENDOR);
} else {
$vendor = Vendor::scope($vendorPublicId)->first();
}
if ($canSaveVendor) {
$vendor = $this->vendorRepo->save($data['vendor']);
}
if ($canSaveVendor) {
$data['vendor_id'] = $vendor->id;
}
}
$expense = $this->expenseRepo->save($data, $expense);
$vendor = $expense->vendor;
$vendor->load('vendor_contacts');
return $expense;
This is the code to execute when we want to save a vendor :
if ($vendor) {
// do nothing
} elseif (!$publicId || $publicId == '-1') {
$vendor = Vendor::createNew();
} else {
$vendor = Vendor::scope($publicId)->with('vendor_contacts')->firstOrFail();
\Log::warning('Entity not set in vendor repo save');
}
$vendor->fill($data);
$vendor->save();
$first = true;
$vendorcontacts = isset($data['vendor_contact']) ? [$data['vendor_contact']] : $data['vendor_contacts'];
foreach ($vendorcontacts as $vendorcontact) {
$vendorcontact = $vendor->addVendorContact($vendorcontact, $first);
$first = false;
}
when I try to save itsaves correctly the vendor in vendors table ,but neither the expense no the vendor_contacts
and it gives me Undefined index: vendor_contacts
what should I do please ?

You made mistake here:
$vendorcontacts = isset($data['vendor_contact'])
? [$data['vendor_contact']]
: $data['vendor_contacts'];
try like this:
$vendorcontacts = isset($data['vendor_contact'])
? [$data['vendor_contact']]
: [];
