我需要能够从这些单选按钮选项中获取帖子信息（在PHP中），所以我可以这样做：

if（is_a_buyer）{ 做这个 } else { 做点别的 }

非常感谢任何帮助！

Answer 1

检查$_POST全局变量。看看你做了什么：

var_dump($_POST);

所选单选按钮的值应为$_POST['userfield[field6]']

Answer 2

<form name="something" action="check.php" method="POST">
<tr>
    <td valign="top">
        <label for="rb_cpf_field6_1">
            Seller: I would like to list my equipment 
        </label>
        <input type="radio" name="userfield[field6]" value="1" id="rb_cpf_field6_1" checked="checked" />
    </td>
</tr><tr>
    <td valign="top">
        <label for="rb_cpf_field6_2">
            Buyer: I'd like to inquire about a listing
        </label>
        <input type="radio" name="userfield[field6]" value="2" id="rb_cpf_field6_2"  />
    </td>
</tr><tr>
    <td valign="top">
        <label for="rb_cpf_field6_3">
            Both: I'm interested in buying and selling
        </label>
        <input type="radio" name="userfield[field6]" value="3" id="rb_cpf_field6_3"  />
  </td>
</tr><tr>
    <td valign="top">
        <label for="rb_cpf_field6_4">
            Other: I'm here for another purpose
        </label>
    <input type="radio" name="userfield[field6]" value="4" id="rb_cpf_field6_4"  />
  </td>
</tr>
</form>

这是你的主要代码（我添加了表单标签，认为它已经不存在。如果有，请删除它们。）

现在，在check.php页面上，请使用：

if ($_POST['userfield[field6]'] == 2 || $_POST['userfield[field6]'] == 3) {
    do this;
}
else {
    do something else;
}

Answer 3

if (isset($_POST['insertRadioButtonName']) == radioButtonValue || isset($_POST['insertOtherRadioButtonName']) == otherRadioButtonValue) {
    echo 'idk';
} else {
    echo 'something';
}
