TaElm :
I have the following code to send chipsData from chips to an input form.
onChipAdd: (event, chip, modal) => {
var chipsData = M.Chips.getInstance($('.chips')).chipsData;
var chipsDataJson = JSON.stringify(chipsData);
$('#ModalEdit #userEventData').val(chipsDataJson);
},
onChipSelect: () => {
},
onChipDelete: () => {
var chipsData = M.Chips.getInstance($('.chips')).chipsData;
var chipsDataJson = JSON.stringify(chipsData);
$("#userEventData").val(chipsDataJson);
}
}
The form input field:
<input type="hidden" name="userEventData" id="userEventData" value="">
When I echo it I receive a string as follow: [{"tag":"name1"},{"tag":"name2"}]
I am looking for a solution to transfer it from a string to an array for later insert it to a database. Any ideas?
*I already checked other Question and could find any solution. (How to store and retrieve materializecss chips?)
ArSeN :
What you are getting is so called JSON encoded data. You can decode it in PHP using the json_decode() function, which will (in your case) give you a two-dimensional array to work with:
$json = '[{"tag":"name1"},{"tag":"name2"}]'
var_export(json_decode($json, true));
output:
array (
0 =>
array (
'tag' => 'name1',
),
1 =>
array (
'tag' => 'name2',
),
)
Note that I passed true as the second parameter to json_decode() since I like to work with arrays rather than objects.
