我正在尝试制作一份简单的预订表格。
1st显示数据库页面中的可用城市和包
当用户点击页面中的BOOK
按钮时,页面将重定向到操作页面,其中所选表单/包应自动添加到booking
表格并发送确认邮件。
以下代码从数据库生成可用的包:
include 'inc/db_connect.php';
//与DB连接工作
$sql="SELECT pkg, fcity, dcity, price, details FROM tour_package WHERE fcity='".$fcity_search."' ORDER BY fcity ASC";
$sqlresult=mysqli_query($con,$sql);
$afct=mysqli_affected_rows($con);
while($pkg=mysqli_fetch_array($sqlresult,MYSQLI_ASSOC)){
$num[]=$pkg['pkg'];
$fcity[]=$pkg['fcity'];
$dcity[]=$pkg['dcity'];
$price[]=$pkg['price'];
$details[]=$pkg['details'];
$num++;
}
$i=0;
$book_btn_id = 1;
while($i < $afct)
{
echo '<form action="book_tour_action.php">';
$num_var_to_db = $num[$i];
echo '<span class="search-class-row"><div class="search-results-label">Package : </div>'.$num[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">From : </div>'. $fcity[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">Destination : </div>' . $dcity[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">Price : </div>' .$price[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">Details :</div>' . $details[$i].'<br/></span>';
//echo '<a href="#" class="booking-btn" name="bb'.$book_btn_id++.'"> BOOK </a>';
echo '<input type="submit" value="BOOK" class="booking-btn" name="bb'.$book_btn_id++.'">';
echo '<br><br/><hr/>';
$i++;
echo '</form>';
}
我已为BOOK
按钮设置动态名称。
book_tour_action.php:
echo $num_var_to_db;
$sql = "INSERT INTO booking (num_var_to_db)
VALUES ('$num_var_to_db')";
但是当点击BOOK
按钮时它显示UNDEFINED VARIABLE。
这意味着数据不会传递给book_tour_action.php
我猜。
我怎样才能使它发挥作用?
答案 0 :(得分:1)
您需要在表单中的隐藏输入字段中保留$num_var_to_db
值才能获取值。尝试如下:
echo '<form action="book_tour_action.php">';
$num_var_to_db = $num[$i];
echo '<input type="hidden" name="num_var_to_db" value="'.$num_var_to_db.'">'
echo '<span class="search-class-row"><div class="search-results-label">Package : </div>'.$num[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">From : </div>'. $fcity[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">Destination : </div>' . $dcity[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">Price : </div>' .$price[$i].'<br/></span>';
echo '<span class="search-class-row"><div class="search-results-label">Details :</div>' . $details[$i].'<br/></span>';
//echo '<a href="#" class="booking-btn" name="bb'.$book_btn_id++.'"> BOOK </a>';
echo '<input type="submit" value="BOOK" class="booking-btn" name="bb'.$book_btn_id++.'">';
echo '<br><br/><hr/>';
$i++;
echo '</form>';
并在php页面中,您可以执行以下操作来获取值:
$num_var_to_db = $_REQUEST['num_var_to_db'];
