使用最后选择的值设置下拉列表的默认值 [英] Set the default value of drop-down list with the last value chosen

问题描述

我正在使用cakephp 1.2，并且具有一个包含以下菜单的搜索表单:

I'm using cakephp 1.2, and I have a search form which has also this menu:

Classificazione&nbsp;&nbsp;<select style="margin-top: 5px;" name="classificazione">
            <option value="art0"></option>
            <option value="C">Articoli</option>
            <option value="D">Documentazione</option>
            <option value="A">Libri</option>
            <option value="G">Materiali</option>
            <option value="B">Riviste</option>
            <default value="A">
</select><br />

在下一页中，我想使用用户之前选择的内容来设置此菜单的默认值.

In the next page I want to set the default value of this menu with what the user has chosen before.

我这样解决(例如，使用第一个选项):
在控制器中:

I SOLVED like this (for example, with the first option):
In the controller:

$getParams['classificazione'] = isset($params['classificazione']) ? $params['classificazione'] : '';
...
$this->set('getParams', $getParams);            

在视图中:

In the view:

<option value="C" <?php if ($getParams['classificazione']=="C") echo "selected"; ?> >Articoli</option>

推荐答案

将值保存在会话变量中，并使用该值回显该选项的selected

Save the value in a session variable and use that to echo selected for that option

<?php
    function is_selected($selected_option, $list_option_value) {
       if($selected_option == $list_option_value) {
          return 'selected';
       }
    }
?>

<select>
   <option <?php echo is_selected($_SESSION['selected_option'], '1'); ?>>1</option>
</select>
