php empty data record deletion - php

Question

There is no problem when the form is sent normally, but when I click on the add-phone button with jquery, input
I have an inpute with name sub_phone_ and when I post it, it is saved in the content named sub_email, sub_map and sub_maps which I did not add to the database in php. I want that if there are no email map maps inputs, they should not write them in the database.
database record
[{"title":"1","address":"1","phone":"1","submenu":[{"email":"1","phone":null,"map":null,"maps":null}]}]
if empty
"phone":null,"map":null,"maps":null <<< delete.

Answer 1

You can Try following code.
foreach (post('title') as $key => $title) {
$arr = [
'title' => $title,
'address' => $address[$key],
'phone' => $phone[$key],
];
if (post('sub_email_' . $key) != null) {
if (post('sub_email_' . $key)) {
$submenu = [];
$subphone = post('sub_phone_' . $key);
$submap = post('sub_map_' . $key);
$submaps = post('sub_maps_' . $key);
foreach (post('sub_email_' . $key) as $k => $subemail) {
if (($subphone[$k] != null) && ($submap[$k] != null) && ($submaps[$k] != null)) {
$submenu[] = [
'email' => $subemail,
'phone' => $subphone[$k],
'map' => $submap[$k],
'maps' => $submaps[$k]
];
}
}
if (count($submenu) > 0) {
$arr['submenu'] = $submenu;
}
}
}
$menu[] = $arr;
}
$result=DB::table('menu')
->insert([
'menu_title' =>$menu_title,//your menu title here
'menu_content' => json_encode($menu)
]);
I hope it's works for you.
