Only allowing selection of one radio button in a form with PHP
提问by cw84
A very basic question...
一个非常基本的问题...
How can I only allow the selection of one option in a list of radio buttons?
如何只允许在单选按钮列表中选择一个选项？
<form action="process_repair.php" method="POST">
<label for "repair_complete">Repair complete</label>
<input type="radio" name="Yes" value="true">
<input type="radio" name="No" value="false">
</form>
When this code runs, it's possible to select both radio buttons, but I'd like them to interact so you can only select one or the other.
当此代码运行时，可以同时选择两个单选按钮，但我希望它们进行交互，因此您只能选择其中一个。
Any help much appreciated! :)
非常感谢任何帮助！:)

Give them the same name.
给它们起相同的名字。
<form action="process_repair.php" method="POST">
Repair complete
<input type="radio" name="complete" value="true" id="complete_yes" />
<label for="complete_yes">Yes</label>
<input type="radio" name="complete" value="false" id="complete_no" />
<label for="complete_no">No</label>
</form>
Labels must have a forattribute, directing to the corresponding input's id.
标签必须有一个for属性，指向相应输入的id.

Every input should have same "name"
每个输入都应该有相同的“名称”
