如何将变量从一个页面上的输入框传递到另一个页面并使用此信息在第2页上执行搜索?

标签: php javascript css forms input

我确信答案很容易,但我是一个php / javascript noob,因此我的问题。前三段代码以“echo $ _POST ['new_search_text'];”结尾,视觉上完美,但现在我想弄清楚如何在第一部分的表单中输入输入并用于搜索条件在我的搜索页面上(搜索页面代码以“{include file ='header.tpl'}”开头,以“{include file ='footer.tpl'}”结尾。我喜欢它所以传递的信息会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”然后让它在搜索页面上显示结果一样。我正在使用智能模板,并且还在搜索页面中包含了后端骨骼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!

    <form id="searchForm" action="./search.php" method="post">

        <input type="submit" value="Search">

    function showSearchForm() {
        // show the form by setting style="display:inline"
        document.getElementById('searchForm').style.display = 'inline';
        // hide the link by setting style="display:none"
        document.getElementById('searchLink').style.display = 'none';
    }

        // hide the form
        document.getElementById('searchForm').style.display = 'none';

您可能需要采取几种方法来实现这一目标。一种方法是编写一个javascript函数,检查POST var'new_search_text'的存在,然后以编程方式将此字符串放在搜索框中,如果找到则提交表单。

<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>

在旁注中,你提到你不能使用jQuery但是在js代码中将自动焦点设置为你正在使用jQuery的搜索字段。如果需要删除jQuery,可能需要查找设置焦点的直接javascript方式。

@ 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,第三个代码位是第二页的相关搜索表单。它不会出错,当我输入搜索查询并点击提交时会转到搜索页面,但它不会搜索输入的文本或做任何事情,除非刷新自己....任何想法?

<script type="text/javascript">
<!-- 
  function checkForAutoSearch()
  {
    var searchString = <?php echo (!empty($_POST['new_search_text'])) ? $_POST['new_search_text'] : ''; ?>;

    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_new"
      // then submit the form:
      document.getElementById('search_form_new').submit();
    }
  }

  // now fire this function whenever the page loads
  window.onload = checkForAutoSearch;
//-->
</script>
