当我按下提交按钮将数据发送到服务器时，使用php，当脚本返回时，我需要同时出现yes和no按钮来批准或取消批准发送的数据。。。请帮忙！我在if/else-if语句中迷路了
if (filter_has_var(INPUT_POST, "office")){
$office = filter_input(INPUT_POST, "office");
print "<span>, your office is room $office</span>";
}
if (filter_has_var(INPUT_POST, "os")){
$os = filter_input(INPUT_POST, "os");
print "<span>, and your OS is $os</span>";
}
if($_POST['submit']== 'yes'){
echo "Thanks!";
}elseif($_POST['submit']=='no'){
return form();
}
else{
//there's no input. Create the form
print <<< HERE
<form action ="" method="post">
<fieldset>
<label>Enter your name</label>
<input type = "text"
name = "name"/><br>
<label>Employee ID</label>
<input type = "text"
name = "id"/><br>
<label>Office Room Number</label>
<input type = "text"
name = "office"/><br>
<label>Oberating System on the Office Computer</label>
<input type = "text"
name = "os"/><br>
<input type="submit" name="submit" value="submit">
<input type="hidden" name="yes" value="yes">
<input type="hidden" name="no" value="no">
</fieldset>
</form>
HERE;
}
// end 'value exists' if
?>
</body>
</html>
您需要分三步而不是两步来完成：
if (yes or no are set as well as the other required form variables){
// step 3
// do final submission
} else if (submit and other required form variables are set){
// step 2
// A. display data.
// B. display form with only yes/no options and no other visible fields
// C. in form also include original submitted data (as hidden fields)
} else {
// step 1
// display empty form with all fields and a submit button
}
如果希望表单可编辑，可以将第二步更改为组合A和C。
