根据选择的单选按钮检查隐藏的输入字段 [英] Check Hidden Input Fields Based On Radio Button Selected

问题描述

我在这里进行了搜索，但是尽管发现了很多类似且很可能更为复杂的情况，但仍找不到我想要做的事情的答案.

I HAVE searched on here but, despite finding LOTS of similar and most likely MUCH more complicated situations, couldn't find an answer to what I am wanting to do.

基本上，我想在我网站的搜索表中显示2个单选按钮选项:

Basically, on my site's search form I want to present 2 radio button options:

<label><input type="radio" name="question_9[]" value="Blue" checked="checked" />Blue</label>    
<label><input type="radio" name="question_9[]" value="Green" />Green</label>

我想用搜索表格提交的是:

BUT what I want to be submitted with the search form is:

<input type="hidden" name="question_9[]" value="Blue"  checked="checked"/>
<input type="hidden" name="question_9[]" value="Blue/Green"  checked="checked"/>

OR

<input type="hidden" name="question_9[]" value="Green"  checked="checked"/>
<input type="hidden" name="question_9[]" value="Blue/Green"  checked="checked"/>

取决于提交表单时选中了哪个单选按钮.

depending on which radio button is checked when the form is submitted.

我正在使用的软件最近从scriptaculous迁移到了JQuery，这是我的新手.我希望有一种基于选择哪个单选按钮为问题传递2个值的简便方法，因为据我所知，除非我采取这种变通方法，否则我只能通过单选按钮选择一个值.由于单选按钮本身不会/不应该使用表单提交值，因此可以重命名它们或进行任何必要的操作以使其起作用.

The software I am using recently migrated from scriptaculous to JQuery, which I am completely new to. I am hoping there is an easy way to pass 2 values for the question based on which radio button is selected, since as far as I know I can only select ONE value with radio buttons unless I do a workaround like this. Since the radio buttons themselves won't/shouldn't be submitting values with the form, they can be renamed or whatever needs be done to make it work.

我真的很感谢任何提示，我再次发现并没有发现另一个问题要求这样做(令我感到惊讶)，但是希望我对这样的问题并没有多余.

I really appreciate any tips and again, I looked and didn't find another question asking to do the same as this (kind of surprised me) but HOPE that I am not being redundant with a question like this.

推荐答案

无论使用单选按钮，复选框，隐藏文本字段还是其他内容，您都无法提交两个具有相同名称的值.您需要考虑处理数据的PHP/ASP脚本会看到什么-例如对于PHP，$ _ POST ['question_9'](或$ _GET ['question_9'])应具有什么值?该值需要从单个字段传递.

You won't be able to submit two values with the same name - whether you use radio buttons, checkboxes, a hidden text field, or whatever. You need to think about what the PHP/ASP script processing your data will see - e.g. for PHP, what value should $_POST['question_9'] (or $_GET['question_9']) have? That value needs to be passed from a single field.

好消息是，您不需要任何精美的javascript技巧即可将正确的信息传递给脚本.如果您希望PHP变量为蓝色蓝色/绿色"，则只需将单选按钮的值"元素更改为蓝色蓝色/绿色"即可.

The good news is that you don't need any fancy javascript tricks to pass the right info to your script. If you want your PHP variable to be "Blue Blue/Green" you can just change the 'value' element of your radio button to "Blue Blue/Green".

您需要在PHP方面解析您的值-例如

You'll need to parse your values out on the PHP side - e.g.

$colorArray = explode(' ',$_POST['question_9'])

PHP explode()将使用定界符，在此示例中使用空格.

The PHP explode() will break a string into an array using a delimiter, in this example using a space.

为澄清起见，解决方案更简单.单选按钮将使您知道是否提交了蓝色或绿色-如果您还希望同时将蓝色/绿色作为"question_9"数组的一部分提交，则无论是否选中了蓝色或绿色，您都应该只添加一个即可如您所说的隐藏字段(删除选中"属性，因为它仅适用于复选框和单选按钮):

In response to the clarification, the solution is simpler. The radio button will get you whether Blue or Green is submitted - if you want to also submit Blue/Green with it as part of the "question_9" array regardless of whether Blue or Green is checked, you should be able to just add a single hidden field like you said (removing 'checked' attribute since it only applies to checkboxes and radio buttons):

<input type="hidden" name="question_9[]" value="Blue/Green"/>
