使用PHP注册表格中的单选按钮同意或不同意条款和条件

Question

I've searched for this answer and cannot find it. If you can point me to it, I will look at it. I'm working in Dreamweaver and fairly new to PHP and MySQL etc. My issue is: I have a simple PHP registration form for visitors to fill out (email, username, password and radio buttons for "Agree to terms" or "Disagree") so they can log into my site and view content. All works fine except I want visitors to click on "Agree to terms", otherwise it will not let them in. As of now, I can still create new accounts (in my testing) regardless of leaving the selection on disagree. I have seen answers using JavaScript but is there an answer in PHP? Here is that portion of the form if it helps. Thank you in advance.

 <label> <input name="AgreeDisagree" type="radio" required id="AgreeDisagree_0" form="register"> I agree to the <a href="agreement.html">Terms and Conditions</a></label> <br> <br> <label> <input name="AgreeDisagree" type="radio" id="AgreeDisagree" value="radio" checked="checked"> I disagree.</label>

您需要将每个单选字段中的值分别设置为“同意”和“不同意”（不是“ radio”），然后让后端代码确保$_POST['AgreeDisagree'] == "agree"
