Javascript 基于jQuery的多搜索栏过滤结果

我希望用户能够基于键入多个搜索栏组件来搜索工作，但在我的代码中，它可以基于一个搜索栏进行搜索。为此，我使用了两个变量search和search2，它只能对search变量起作用

html:

javascript:

my search.php页面：

---

我有两个输入字段，一个用于jobtitle，一个用于city，基于此，我需要相关输出，例如：jobtile='software devloper'和city='delhi'，我的数据库仅显示city delhi上的软件devloper结果

search.php：

if(isset($_GET['filter']) && $_GET['filter']=='searchBar')
        {

                $search = $_GET['search'];
                $search2 = $_GET['search2'];
                $sql = "SELECT * FROM job_post INNER JOIN company ON job_post.id_company=company.id_company WHERE jobtitle LIKE '%$search%' OR city LIKE '%$search2%' LIMIT $start_from, $limit";
        }

        else if(isset($_GET['filter']) && $_GET['filter']=='experience')
        {
            $sql = "SELECT * FROM job_post WHERE experience >='$_GET[search]' LIMIT $start_from, $limit";
        }

        $result = $conn->query($sql);
        if($result->num_rows > 0)
        {
            while($row = $result->fetch_assoc())
            {
                $sql1 = "SELECT * FROM company WHERE id_company='$row[id_company]'";
                $result1 = $conn->query($sql1);
                if($result1->num_rows > 0)
                {
                    while($row1 = $result1->fetch_assoc()) 
                    {
    ?>

                      <div class="attachment-block clearfix">
                      <img class="attachment-img" src="uploads/logo/<?php echo $row1['logo']; ?>" alt="Attachment Image">
                      <div class="attachment-pushed">
                      <h4 class="attachment-heading"><a href="view_job_post.php?id=<?php echo $row['id_jobpost']; ?>"><?php echo $row['jobtitle']; ?></a> <span class="attachment-heading pull-right">$<?php echo $row['maximumsalary']; ?>/Month</span></h4>
                      <div class="attachment-text">
                          <div><strong><?php echo $row1['companyname']; ?> |\ <?php echo $row1['city']; ?> | Experience <?php echo $row['experience']; ?> Years</strong></div>
                      </div>
                      </div>
                      </div>
    <?php
                    }
                }
            }
        } 
    }
    $conn->close();
    ?>

你们能更具体地描述一下你们面临的问题吗？所以，我的问题不适合一个职位，所以，我必须在另一个职位上修改或继续我的发回问题
