Add voting options
Here you need to query and display all the voting questions that have been added:
<?php <select style="width:300px;" name="subject"> <option value="" checked>请选择问题</option> <?php $result = $db->query("select * from votename"); while($row = mysqli_fetch_assoc($result)){ ?> <option value="<?php echo $row['cid']; ?>"><?php echo $row['question_name']; ?></option> <?php } ?> </select>
All codes:
<?php include('../conn.php'); if(isset($_POST['voteoption'])?$_POST['voteoption']:''){ $voteoption = $_POST['voteoption']; $subject = $_POST['subject']; if($subject == ""){ echo "<script>onload = function(){document.getElementById('errortext').innerHTML='请选择问题!';}</script>"; }else{ $result = $db->query("insert into voteoption (optionname, upid, votenum) values ('$voteoption', '$subject', '0')"); if($result){ echo "<script>onload = function(){document.getElementById('errortext').innerHTML='添加选项成功';}</script>"; }else{ echo "<script>onload = function(){document.getElementById('errortext').innerHTML='添加选项失败';}</script>"; } } } ?> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script type="text/javascript" src="js/jquery.min.js"></script> <link rel="stylesheet" href="css/add.css" type="text/css" media="screen" /> <link rel="stylesheet" href="utilLib/bootstrap.min.css" type="text/css" media="screen" /> </head> <body> <div class="div_from_aoto" style="width: 500px; margin:30px 40px;"> <FORM action="Addvoteoption.php" method="post" enctype="multipart/form-data" name="form1" id="form1"> <div id="result111" class="result111" style="width:300px; height:20px; margin:4px auto; color:#33FF99; "> <h5 id="errortext"></h5> </div> <DIV class="control-group"> <label class="laber_from">投票选项</label> <DIV class="controls" ><INPUT class="username" style="width:300px;" name="voteoption" type=text placeholder=" 请输入投票选项"><P class=help-block>不要超过20个字</P></DIV> </DIV> <DIV class="control-group"> <label class="laber_from">所属问题</label> <DIV class="controls" ><select style="width:300px;" name="subject"> <option value="" checked>请选择问题</option> <?php $result = $db->query("select * from votename"); while($row = mysqli_fetch_assoc($result)){ ?> <option value="<?php echo $row['cid']; ?>"><?php echo $row['question_name']; ?></option> <?php } ?> </select> <P class=help-block></P></DIV> </DIV> <DIV class="control-group"> <LABEL class="laber_from" ></LABEL> <DIV class="controls" ><button class="btn btn-success" style="width:120px;" >添加选项</button></DIV> </DIV> </FORM> </div> </body> </html>
