Put JSON data into html form input checkbox with PHP

Question

I want to put json data into html form input checkbox with laravel blade.

I have multiple input checkbox values as test[],

Then I try use htmlspecialchars to print values into input.

If my frontend check this input, backend use print_r is like this

Array
(
    [0] => {"value1":"tool_ad_id","value2":"\u65e5\u4ed8"}
    [1] => {"value1":"ad_group1","value2":"\u30c4\u30fc\u30eb\u5e83\u544aID"}
)

but I use return $request->test['0']['value1']; can't get a value.

I want to get 'value1' and 'value2'.

PHP Laravel

@foreach($as as $key => $value)
      <div class="col s6 m4 l3 blue-grey lighten-5">
      <?php
            $data = ['value1' => $value['en'] ,'value2' => $value['jp'] ];
            $data_total = htmlspecialchars(json_encode($data));
       ?>
        <input type="checkbox" id="test5{{ $key }}" value="{{$data_total}}" name="test[]" />
        <label for="test5{{ $key }}">{{$value['jp']}}</label>
      </div>
@endforeach

Laravel Controller

return $request->test['0']['value1'];

Error message

Illegal string offset 'value1'

[0] => {"value1":"tool_ad_id","value2":"\u65e5\u4ed8"}
Index => String

PHP does not parse JSON, you are receiving the JSON as normal string. Therefore, in order to convert it to a PHP object with properties correspongind to the keys, you need to use json_decode().

Try $test = json_decode($request->test['0'], true), and then access values off the $test variable.

$value1 = $test['value1'];
$value2 = $test['value2'];

Do not try json_decode($request->test['0']['value1'], true) just json_decode($request->test['0'], true) and then try and access 'value1'
