loop over an array sent with ajax to controller
Hello , i'm using an ajax post request to send an array ( selectedids) to the controller
$.ajax({
type:'POST',
url:'{{action('OrderController@ajaxRequestPost')}}',
data: { "type":strUser , "_token": "{{ csrf_token() }}","ids":JSON.stringify(selectedIds)},
dataType: 'json',
success:function(data){
alert(data);
},
error: function(xhr, textStatus, thrownError) {
alert(' Error');
}
});
but i cannot loop over it in the controller i tried json_decode but it didn't work
the only thing that worked is :
echo $request->get("ids");
it shows this : 14,21,12 how can i iterate over it to get all the ids
thank you

As you said if the output is "14,21,12", json_decode("14,21,12") won't work because it is not a valid Json.
If you want to decode a Json array string, the passed input should be "[14,21,12]". This should decode to an array and you can iterate over it.
In your case, try this in your data key,
data: { "type":strUser , "_token": "{{ csrf_token() }}","ids":"["+JSON.stringify(selectedIds)}+"]",
Also, you can refer json validator sites like https://jsonlint.com/ to check for any input is a valid json so that it can be decoded using json_decode method.

this didn't work i tried to echo echo $request->get("ids"); and i gives 12,13 and when i tried json_decode i got error 500 internal server error
Level 102
Well if they are just comma separated you can just do
$array = explode(',' $request->get('ids'));

i tried it but it gives me error 500 internal server error
Level 102
My best bet is you have a typo. Missing ' or ;
Level 1
well i just tried this
data: { "type":strUser , "_token": "{{ csrf_token() }}",ids:JSON.stringify(selectedIds)}, removed the " " from ids
and the output is this [["12","14","15"]]
the json_decode still not working

Or just send a regular array in the post.
Level 102
It is most likely already decoded. Just try looping over it (or use dd() to check the data. It is much better than echo)
Level 1
that's what i'm trying to do
Level 102
So if you dd the output, what do you get exactly?
Level 75
@sinnbeck will dd work with ajax, or will browser developer tools be a better choice.
Level 1
@sinnbeck dd doesn't work with ajax it just gives me error 500
Level 75
Why don't you use browser developer tools to help troubleshoot.
Level 1
so basically if i use JSON.stringify and then try to use json_decode i get the error array to string conversion same thing happens when i don't use JSON.stringify and try to access it as an array
Level 1
i solved it using selected = JSON.parse("[" + selectedIds + "]")
and then
data: { "type":strUser , "_token": "{{ csrf_token() }}",ids:JSON.stringify(selected)},
and on php i used json_decode
thank you for your help
