请记住多个Dropbox PHP变量

Question

我需要为视频创建一个flver。一个保管箱选择视图数量和其他类别。在这个网站上的优秀人士的帮助下，我设法创建了列表，但我不知道如何让它们“记住”两者的数据 - 当从一个下拉列表中选择一个值时，其他下拉列表将重置。我如何解决这个问题？

这里是代码：

<?php 
$views = (int) $_GET['views']; 
$countries = "US"; 
$category =$_GET['category']; ?> 
<div id="views"> 

<p> 
View videos with 
    <form name="views" method="GET" action="random.php"> 
     <select name='views' onChange='document.views.submit()'> 
      <? $views_options = array (0, 50, 100, 500, 5000, 35000, 75000, 125000, 150000, 250000, 500000, 1000000, 3000000, 5000000, 10000000, 15000000, 20000000); 

foreach($views_options as $number_of_views) { 
    echo '<option value="' . $number_of_views . '"' . ($_GET['views']==$number_of_views ? ' selected="selected"' : '') . '>' . number_format($number_of_views) . '</option>'; 
} 
?> 
    </select> 
     </form> 
    <p>views or more 
    </p> 

</div> 

<div id="category"> 

<p> 
Category: 
    <form name="category" method="GET" action="random.php"> 
     <select name='category' onChange='document.category.submit()'> 
      <? $category_options = array ("All", "Games", "Film", "Animals", "Travel", "Sports", "Education", "News", "Shows", "People", "Technology", "Comedy", "Entertainment", "Music", "Howto", "Autos", "Nonprofit"); 

foreach($category_options as $category_select) { 
    echo '<option value="' . $category_select . '"' . ($_GET['category']==$category_select ? ' selected="selected"' : '') . '>' . $category_select . '</option>'; 
}?> 
    </select> 
     </form>

我认为你不需要为这两个不同的形式。

合并两种形式为一体，所以它应该工作：

<?php 
$views = (int) $_GET['views']; 
$countries = "US"; 
$category =$_GET['category']; ?> 
<div id="views"> 

<p> 
View videos with 
    <form name="views" method="GET" action="random.php"> 
     <select name='views' onChange='document.views.submit()'> 
      <? $views_options = array (0, 50, 100, 500, 5000, 35000, 75000, 125000, 150000, 250000, 500000, 1000000, 3000000, 5000000, 10000000, 15000000, 20000000); 

foreach($views_options as $number_of_views) { 
    echo '<option value="' . $number_of_views . '"' . ($_GET['views']==$number_of_views ? ' selected="selected"' : '') . '>' . number_format($number_of_views) . '</option>'; 
} 
?> 
    </select> 
    <p>views or more 
    </p> 

</div> 

<div id="category"> 

<p> 
Category: 
     <select name='category' onChange='document.views.submit()'> 
      <? $category_options = array ("All", "Games", "Film", "Animals", "Travel", "Sports", "Education", "News", "Shows", "People", "Technology", "Comedy", "Entertainment", "Music", "Howto", "Autos", "Nonprofit"); 

foreach($category_options as $category_select) { 
    echo '<option value="' . $category_select . '"' . ($_GET['category']==$category_select ? ' selected="selected"' : '') . '>' . $category_select . '</option>'; 
}?> 
    </select> 
     </form> 

因为你曾使用过两种形式仅下拉式菜单中的一个获得提交的（例如，你提交的类别，下拉“意见”将是空的（你正在使用GET方法，你会在你的URL中看到这个））。

如果你真的需要这个单独的两个表单，你将不得不将你的变量保存到PHP会话中。
