Question

我已经简化了这个问题。但是，如果选中按钮组合，我需要做的就是显示不同的结果。如果检查大米和茶，那么没有结果。

<?PHP

if (isset($_POST['Submit1'])) {

    $selected_radio = $_POST['food']."|".$_POST['drink'];

        if ($selected_radio == 'rice' && 'tea') {
            print '<h1>Rice and tea</h1>';

        }
        else if ($selected_radio == 'beans' && 'coffee') {
            print '<h1>Beans and coffee</h1>';
        }
}

?>  


<form name ="form1" method ="POST" action =" ">

<p><input type = 'Radio' Name ='food'  value= 'rice'>Rice</p>

<p><input type = 'Radio' Name ='food'  value= 'beans'>Beans</p>


<p><input type = 'Radio' Name ='drink'  value= 'tea'>Tea</p>

<p><input type = 'Radio' Name ='drink'  value= 'coffee'>Coffee</p>


<input type = "Submit" Name = "Submit1"  value = "Select">
</form>

（早先提出类似问题道歉）

Answer 1

条件

时更新

if (isset($_POST['Submit1'])) {

    $selected_radio = $_POST['food']."|".$_POST['drink'];

        if ($selected_radio == 'rice|tea') {
            print '<h1>Rice and tea</h1>';

        }
        else if ($selected_radio == 'beans|coffee') {
            print '<h1>Beans and coffee</h1>';
        }
}

Answer 2

更改if：

的条件

    if (strpos($selected_radio, 'rice') !== FALSE && strpos($selected_radio, 'tea') !== FALSE) {
        print '<h1>Rice and tea</h1>';

    }
    else if (strpos($selected_radio, 'beans') !== FALSE && strpos($selected_radio, 'coffee') !== FALSE) {
        print '<h1>Beans and coffee</h1>';
    }

（这只是一个建议，我没有测试过;））

Answer 3

$ selected_radio_list = array（＆＃39; rice | tea＆＃39; =＆gt;＆＃39; foo＆＃39;，＆＃39;豆|咖啡＆＃39; =＆gt;＆＃39; bar＆＃39 ）;

$ post = $ _POST [＆＃39; food＆＃39;]。＆＃34; |＆＃34;。$ _ POST [＆＃39; drink＆＃39;];

if（in_array（$ post，$ selected_radio_list））

echo $ selected_radio_list [$ post];
