我想从我的网站生成某些条件的报告，该网站是一个Web应用程序，用于节省故障时间和公司机器的详细信息。这里我想根据故障类型，故障机器，故障等产生报告，。
所以我创建了一个搜索表单，我已经使用了数据库中的动态下拉菜单，并成功创建了一个代码，可以选择多个值（在机器下 - 我们可以选择机器名称，如machine1，machine2和等等）按下搜索后，它只显示最后一个选定值的结果，但我想显示所有选定值的结果（详细信息）。
**form.php**
<?php
//index.php
include('database_connection.php');
$country = '';
$query = "
SELECT type FROM reporttype
";
$statement = $connect->prepare($query);
$statement->execute();
$result = $statement->fetchAll();
foreach($result as $row)
{
$country .= '<option value="'.$row["type"].'">'.$row["type"].'</option>';
}
?>
<div class="container">
<h2 align="center"></h2><br /><br />
<form method="post" id="insert_data" action="insert.php">
<label class="col-md-2 bdlabel">Break Down</label>
<select name="country" id="country" class="col-md-10 form-control action">

<?php echo $country; ?>

WHERE bdmwc in ('$city') || bdmname in ('$city') || bdaname in ('$city') ")
or die(mysql_error());
if(mysql_num_rows($raw_results) > 0){ // if one or more rows are returned do following
while($results = mysql_fetch_array($raw_results)){
echo "<p>".$results['bdmwc']."</p>";
}
}
else{
echo "No results";
}
}
?>
What i want to show is wire drawing and nail but only nail value is been shown.

要在表单上获取多个值，您应在NSPredicate属性的末尾添加[]
对于您的示例：

终于找到了答案，我必须使用implode函数来通过数组获取多个值。在搜索查询中使用implode函数后，我能够获得多个值并得到我想要的结果。感谢@RiggsFolly和@OlgertElezi的帮助，select标签中的方括号有助于传递数组值。
我附上了我的工作代码。再次感谢evryone
