Question

您好我有一个用PHP编写的程序。我想选择一个类别并显示相关的文章。我选择了一个类别，但没有显示出一个关键词。有人帮帮我吗？

catalogo.php

        <div class="col-md-4-fluid">
            <form class="navbar-form navbar-left" role="search" action="buscartipo.php" method="post" enctype="multipart/form-data" class="pull-right">

                <div class="input-group">
                    <select class="form-control" name="tipo">
                        <option value="" selected="selected">Buscar por tipo</option>
                        <option value="tecnologia">Llave T</option>
                        <option value="deportes">Herramientas especiales</option>
                        <option value="arte">Kit de puesta a punto</option>
                        <option value="viajes">Otros</option>
                    </select>
                    <span class="input-group-btn">

值由buscartipo.php

接收

<?php
session_start();

$tipo=$_POST['tipo'];

if(empty($tipo)){
    echo "<script>alert('Seleccione un tipo de plantilla')</script>";
    echo "<script>location.href='catalogo.php'</script>";
