Question

我试图在截止日期即将到来之前解决这个问题，以便获得任何帮助。

<form id="searchdivebay" action="searchdivebay.php" method="get" target="results">
    <div class="searchbox"><input type="text" name="searchbox" id="searchboxinput"/></div>
    <div class="searchbtn"><input type ="submit" name="searchbutton" value="Search DiveBay"/></div>
</form>

是我的html表单。

我需要获取searchbox输入字段的值，以用作php脚本中的sql查询。我的脚本工作，因为我用's'替换$ _GET ['searchbox']来测试它。由于某种原因，在提交表单时没有启动php脚本，我不知道该怎么做。任何人都可以看到脚本或HTML的错误？非常感谢。

Answer 1

也许是一个远景，但'type =“submit”'中有一个空格。如果空白区域存在，您的浏览器无法将提交按钮识别为提交按钮，因此无法提交您的表单。

Answer 2

如果您在Firefox或Chrome上测试表单，我建议使用firebug或开发人员工具查看传递给服务器的数据。在chrome中，我会查看网络选项卡，对firebug不太确定。另外我认为可能与表单上的target属性有关。结果是合法的框架名称吗？

得到的搜索输入是PHP脚本，不工作？
