我的网站上有一个民意调查,每个答案旁边都会显示单选按钮。当用户选择一个选项并提交时,我通过 ajax 运行一个 php 脚本以将值或选定的单选按钮插入表中。
我的 Ajax 正在运行,但当前每行插入 0 行,因此它没有从单选按钮中获取值。任何帮助,将不胜感激。
HTML:
<form id="poll_form" method="post" accept-charset="utf-8">
<input type="radio" name="poll_option" value="1" id="poll_option" /><label for='1'> Arts</label><br />
<input type="radio" name="poll_option" value="2" id="poll_option" /><label for='2'> Film</label><br />
<input type="radio" name="poll_option" value="3" id="poll_option" /><label for='3'> Games</label><br />
<input type="radio" name="poll_option" value="4" id="poll_option" /><label for='4'> Music</label><br />
<input type="radio" name="poll_option" value="5" id="poll_option" /><label for='5'> Sports</label><br />
<input type="radio" name="poll_option" value="6" id="poll_option" /><label for='6'> Television</label><br />
<input type="submit" value="Vote →" id="submit_vote" class="poll_btn"/>
</form>
阿贾克斯:
$("#submit_vote").click(function(e)
{
var option=$('input[type="radio"]:checked').val();
$optionID = "="+optionID;
$.ajax({
type: "POST",
url: "ajax_submit_vote.php",
data: {"optionID" : $optionID}
});
});
PHP:(缩短版)
if($_SERVER['REQUEST_METHOD'] == "POST"){
//Get value from posted form
$option = $_POST['poll_option'];
//Insert into db
$insert_vote = "INSERT into poll (userip,categoryid) VALUES ('$ip','$option')";
提前致谢!
