如何在php中的兩個表中創建一個搜索功能

Question

我目前有這個問題在我的項目在某個主題。我想知道是否可以從mysql中的兩個表創建一個搜索功能。 我不能用文字來解釋它，所以我會爲此提供代碼。

<table class="table table-striped"> 
       <th>Date of Request</th> 
       <th>Brand</th> 
       <th>Model</th> 
       <th>Plate Number</th> 
       <th>Problem Description</th> 
       <th>Parts Replaced</th> 
       <th>Date Repair Completed</th> 


      <th></th> 
      <?php 
       require_once("db_open.php"); 
       $sql = "SELECT v.*, rt.* FROM vehicle v, repair_transaction rt WHERE v.Vehicle_Id = rt.Vehicle_Id 
       ORDER BY Date_of_repair_request ASC"; 
       $result = $conn->query($sql) or die($conn->error); 
       if ($result->num_rows > 0) { 
        while($row = $result->fetch_assoc()) { 

         echo "<tr>"; 
         echo "<td>".$row["Date_of_repair_request"]."</td>"; 
         echo "<td>".$row["Brand"]."</td>"; 
         echo "<td>".$row["Model"]."</td>"; 
         echo "<td>".$row["Plate_No"]."</td>"; 
         echo "<td>".$row["Problem_Description"]."</td>"; 
         echo "<td>".$row["Parts_replaced"]."</td>"; 
         echo "<td>".$row["Date_Repair_Completed_by_Maintenance"]."</td>"; 

         echo "</tr>"; 
        } 
       } else { 
        echo "<p>No transaction to show...</p>"; 
       } 

這是兩張表的代碼和圖像。
