[matpache]

Dear, as I can be stored in the "way-data" a set of elements? I need to store in a select multiple options.???

generates the following structure:

way data

{
"requestFoundsTransports": {
"transports": [
{
"transport_participants": {
"[]": "20"
},
"transport_ammount": "1212",
"transport_details": "1ssssss"
}
]
}
}

and I need something like this:

way data

{
"requestFoundsTransports": {
"transports": [
{
"transport_participants": {
"[]": "20,21,23"
},
"transport_ammount": "1212",
"transport_details": "1ssssss"
}
]
}
}

or this way:

way data

{
"requestFoundsTransports": {
"transports": [
{
"transport_participants": {
"[0]": "20",
"[1]": "21",
"[2]": "22"
.......
},
"transport_ammount": "1212",
"transport_details": "1ssssss"
}
]
}
}
