我正在处理一个包含 19 个不同下拉列表的表单。每个列表都有相同的 39 个选项。我希望用户能够在一个或多个列表中选择选项并忽略其他选项。理想情况下,查询将返回 MySQL 数据库中与数据库中相应列中的所有选定选项匹配的行。
前任:
Phoneme 1: AA <--- choice in a dropdown list of 39 items
Phoneme 2: <--- choice in a dropdown list of 39 items
Phoneme 3: CH <--- choice in a dropdown list of 39 items
Phoneme 4: <--- choice in a dropdown list of 39 items
当他们点击提交时,他们将收到数据库中所有在第一个位置有音素 AA 和在第三个位置有音素 CH 的单词。但我似乎无法弄清楚如何忽略他们没有选择的选项。在示例中,他们将音素 2 和 4 留空。我怎样才能让我的查询自动尝试搜索他们选择的那些?
预先感谢您的帮助。我一直在使用的代码如下。目前我没有得到任何结果,尽管数据库中有超过 130,000 个单词,每个单词都有自己的语音构成。
