我相信这个问题的答案很简单，但我是一个php/javascript noob，因此我提出了问题。前三段代码以"echo$_POST['new_search_text']；"结尾，在视觉上非常完美，但现在我想弄清楚如何将第一节表单中输入的输入传递给我，并用于我的搜索页面上的搜索条件（搜索页面代码以"{includefile='header.tpl'｝"开头，以"{ludefile='footer.tpl'}"结尾）。我希望它能让传递的信息自动在搜索页面上搜索，就像我直接在那里输入并点击"搜索"一样在搜索页面上显示结果。我使用的是智能模板，还包含了我搜索页面中的底层PHP代码（以"$page="search"；"开头）。我不能使用Jquery，因为它会干扰其他代码，但我认为解决方案相当简单。
谢谢！！

可能有几种方法可以实现这一点。一种方法是编写一个javascript函数，检查POST var"new_search_text"的存在，然后以编程方式将该字符串放入搜索框中，并在找到时提交表单。
<script>
function checkForAutoSearch()
{
var searchString = <?php echo (!empty($_POST['new_search_term'])) ? $_POST['new_search_term'] : ''; ?>;
if (searchString)
{
// put searchString into the second search field
document.getElementById('search_text').value = searchString;
// up in your search form, assign the form tag an id first: id="search_form"
// then submit the form:
document.getElementById('search_form').submit();
}
}
// now fire this function whenever the page loads
window.onload = checkForAutoSearch;
</script>
附带说明一下，您提到您不能使用jQuery，但在js代码中将自动焦点设置为搜索字段时，您似乎正在使用jQuery。如果需要删除jQuery，则可能需要查找设置焦点的直接javascript方法。
@john mcmahon好的，这是我在search2.tpl中放入的代码（我使用Smarty模板）。第二个代码位是第一页上的搜索表单，而第三个代码位则是来自第二页的相关搜索表单。它不会出错，当我输入搜索查询并单击提交时，它会转到搜索页面，但它不会搜索输入的文本，也不会做任何事情，只是刷新自己。。。。有什么想法吗？
