Now by using following statement I'm assigning this array to smarty template:
$smarty->assign('test_data', $test_data);
现在我想在我的 smarty 模板中打印所有测试的值，即我必须为数组 $test_data['test_details'] 应用循环。我应用了它，但它在 smarty 中无法正常工作。给出一些模糊的结果。我不明白我在哪里犯了错误。你能在这方面帮助我吗？我的代码如下：
<select name="test_id" id="test_id">
<option value="all">All</option>
{foreach from=$test_data item=test key=key}
{foreach from=$test.test_details item=test_detail key=key}
<option value="{$test_detail.test_id}" {if $test_id==$test_detail.test_id} selected="selected"{/if}>{$test_detail.test_name}</option>
{/foreach}
{/foreach}
</select>
【问题讨论】：
-
尝试命名你的循环，
{foreach name = "outer_loop" [...]}和{foreach name = "inner_loop" [...]}看看是否有帮助 -
结果模糊是什么意思？另外，您使用的是哪个版本的 smarty——版本 3 或 2？
