Question

我有这个评级系统，每页一个项目可以正常工作，但我想更改它，以便可以评定多个项目。

每个项目的渲染html都是这样的 - data-id=""包含唯一的ID：

<div class="ratings">
  <span class="ratingAverage" data-av="0"></span>
  <span class="item" data-id="7"></span>
  <div class="bar">
    <span class="bg" style="width: 96%;"></span>
    <span class="stars">
      <span class="star full" data-vote="1">
        <span class="starimg"></span>
      </span>
      <span class="star full" data-vote="2">
          <span class="starimg"></span>
      </span>
      <span class="star full" data-vote="3">
          <span class="starimg"></span>
      </span>
      <span class="star full" data-vote="4">
          <span class="starimg"></span>
      </span>
      <span class="star" data-vote="5">
          <span class="starimg"></span>
      </span>
    </span>
  </div>
  <div class="votes"><span>12 votes</span></div>
</div>

JS：

// Rating
  var average = $('.ratingAverage').attr('data-av');
  function getAvg(average) {
    average = (Number(average) * 20);
    $('.bg').css('width', 0);
    $('.bar .bg').animate({
      width: average + '%'
    }, 500);
  }

  getAvg(average);

  $('.star').on('mouseover', function() {
    var indexAtual = $('.star').index(this);
    for (var i = 0; i <= indexAtual; i++) {
      $('.star:eq(' + i + ')').addClass('full');
    }
  });

  $('.star').on('mouseout', function() {
    $('.star').removeClass('full');
  });

  $('.star').on('click', function() {
    var itemId = $('.item').attr('data-id');
    var vote = $(this).attr('data-vote');
    $.post('vote.php', {
      vote: 'yes',
      item: itemId,
      point: vote
    }, function(data, status) {
      getAvg(data.average);
      var suffix = (data.votes == 1)
        ? "vote"
        : "votes";
      $('.votes span').html(data.votes + " " + suffix);
    }, 'jSON');
  });

但是这个.js为所有项目设置了相同的投票。如何为每件商品收集average并在每件商品上运行getAvg(average)？

vote.php：

<?php
    // Connect to db here.
    if(isset($_POST['vote'])){

        $id = (int)$_POST['item'];
        $points = (int)$_POST['point'];
        $query = $pdo->prepare("SELECT votes, rating FROM ". $DBtable ." WHERE `id` = ?");
        $query->execute(array($id));

        while($row = $query->fetchObject()){
            $pointsUpdate = ($row->rating+$points);
            $voteUpdate = ($row->votes+1);

            $updateQuery = $pdo->prepare("UPDATE ". $DBtable ." SET `votes` = ?, `rating` = ? WHERE `id` = ?");
            if($updateQuery->execute(array($voteUpdate, $pointsUpdate, $id))){
                $avg = round(($pointsUpdate/$voteUpdate),1);
                die(json_encode(array('average' => $avg, 'votes' => $voteUpdate)));
            } else {
                echo "Could not update votes";
            }
        }
    }
?>

我希望这段代码足以证明这个问题。非常感谢你提前。

Transaction::where(function($q) {
        $q->where('seller_id', $this->id)
          ->orwhere('buyer_id', $this->id)
          ->whereIn('concept', ['Lemonway', 'Paypal']);
    })
    ->where('status', 'ok')
    ->get();
