This

$.getJSON('Dashboard/CompaniesWithId', function (data) {
  $.each(data, function (i, item) {
    sellers[i] = item.Name;
    sellersID[i] = item.Id;
  });
}).error(function () {
  console.log("error loading seller to the autocomplete");
});

$("#searchSeller").autocomplete({
  messages: {
    noResults: 'No sellers with this name',        
  },
  minLength: 2,
  delay: 500,
  source: sellers,
});

Should be this

<td><input type="radio" value="<?php echo $row['opt1']. ?>'<br>';/></td>

您忘记关闭输入的值属性。

<input type="radio" value="<?php echo $row['opt1']; ?>"/>
