Question

我目前在某个主题的项目中遇到此问题。我想知道是否可以从mysql中的两个表创建一个搜索功能。我无法用文字解释它，所以我会为此提供代码。

    <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>";
                }

这是两个表的代码和图像。

              <th><input type="text" name="search_brand"></th>

          </thead>
        <?php
            require_once("db_open.php");

            // You can use same code for all input

            $result = $conn->query($sql) or die($conn->error);
            if ($result->num_rows > 0) {

                    echo "<td>".$row["Date_Repair_Completed_by_Maintenance"]."</td>";

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