PHP多选表单插入多个[重复]

Question

我添加了一个选择表单，人们可以在其中选择他们的狗获得的奖励。问题是它只在数据库中插入一个选项，并且它是一个多选。允许人们在选择框中添加所有选项。

$query  = "UPDATE dogs SET ";
    $query .="dog_name = '{$dog_name}', ";
    $query .="affix = '{$affix}', ";
    $query .="owners = '{$owners}', ";
    $query .="sire = '{$sire}', ";
    $query .="dam = '{$dam}', ";
    $query .="dob = '{$dob}', ";
    $query .="sex = '{$sex}', ";
    $query .="award = '{$award}', ";
    $query .="champ = '{$champ}', ";
    $query .= "dog_photo = '{$dog_photo}' ";
    $query .= "WHERE dog_id = {$the_dog_id} ";

    $update_dog = mysqli_query($connection,$query);


<select class="form-control" name="award" multiple="multiple" data-plugin-multiselect data-plugin-options='{ "maxHeight": 200, "enableCaseInsensitiveFiltering": true }' id="ms_example6">
     <option value="JW">JW</option>
     <option value="BOY">Bulldog Of Year</option>
     <option value="BOY">Crufts Champion</option>
     <option value="JC">Junior Champion</option>
        </select>

Answer 1

循环遍历它。

假设你的表单是一个 POST 请求，将字段命名为数组

name="award[]"

然后遍历每个条目。

foreach($_POST['award'] as $award) {
  $query  = "UPDATE dogs SET ";
  $query .="dog_name = '{$dog_name}', ";
  $query .="affix = '{$affix}', ";
  $query .="owners = '{$owners}', ";
  $query .="sire = '{$sire}', ";
  $query .="dam = '{$dam}', ";
  $query .="dob = '{$dob}', ";
  $query .="sex = '{$sex}', ";
  $query .="award = '{$award}', ";
  $query .="champ = '{$champ}', ";
  $query .= "dog_photo = '{$dog_photo}' ";
  $query .= "WHERE dog_id = {$the_dog_id} ";

  $update_dog = mysqli_query($connection,$query);
}
