Answer 1

foreach($search_exploded as $search_each)
{
    $x++;
    if ($x==1)
        $construct="keywords LIKE '%search_each%'";
    else
        $construct="OR keywords LIKE '%search_each%'";
}

你忘了$签到search_each

foreach($search_exploded as $search_each)
{
    $x++;
    if ($x==1)
        $construct="keywords LIKE '%$search_each%'"; //you might have to escape the statement
    else
        $construct="OR keywords LIKE '%$search_each%'";
}

另外，请记住关闭标签的横线。<hr />不是<hr>

Answer 2

如果这是您正在编写的新脚本，我强烈建议您迁移到 MySQLi 而不是 MySQL，因为它现在已被弃用！

您的代码非常草率！花更多时间编写代码并使用体面的 IDE！

让我们从这里开始

    $construct="";
        foreach($search_exploded as $search_each)
                {
                        $x++;
                        if ($x==1) {
                            $construct="keywords LIKE '%search_each%'";
                        }
                        else {
                            $construct="OR keywords LIKE '%search_each%'";
                        }
                }
        $construct="SELECT * FROM trip WHERE $construct";

为什么将 $construct 定义为 null 然后立即执行 if/else？您还以SELECT * FROM trip WHERE OR keywords LIKE.. 个人身份在 else 中读取查询我不知道您要在那里完成什么

%search_each% 

应该

%$search_each%

个人而言，if/else 变量不应该是类似的$construct东西$condition

在第 33 行，你有一个流浪 `

 while ($runrows=mysql_fetch_assoc($run);

            {

不该有;

你在一段时间内打开你的桌子，然后在外面关闭它应该是

  {


     echo "$foundnum results found.<p>";
 echo "<table border='1'>
                        <tr>
                        <th>TYPE</th>
                        <th>HAWB</th>
                        <th>DATE</th>
                        <th>TIME</th>
                        <th>PLATE NO.</th>
                        <th>NO. OF PIECES</th>
                        <th>CARGO MARSHAL</th>
                        <th>BY</th>
                        <th>REMARKS 1</th>
                        <th>REMARKS 2</th>
                        </tr>";
                while ($runrows=mysql_fetch_assoc($run)
            {


                    echo "<tr>";
                    echo "<td>" . $row['Type'] . "</td>";
                    echo "<td>" . $row['HAWB'] . "</td>";
                    echo "<td>" . $row['Date'] . "</td>";
                    echo "<td>" . $row['Time'] . "</td>";
                    echo "<td>" . $row['Plate_no'] . "</td>";
                    echo "<td>" . $row['Pcs'] . "</td>";
                    echo "<td>" . $row['Cargo_Marshal'] . "</td>";
                    echo "<td>" . $row['By'] . "</td>";
                    echo "<td>" . $row['Remarks1'] . "</td>";
                    echo "<td>" . $row['Remarks2'] . "</td>";
                    echo "</tr>";
                      }
                    echo "</table>";
            }

你还有很多缺失的{ }牙套！

我最初打算用 mysqli 重写，但我认为这是你需要自己学习的东西。

编辑！！！：你应该清理（去除 html/tags）你从用户输入的表单中得到的任何东西！
