動的ドロップダウンメニューが機能しない

Question

通知タブを機能させようとしていますが、正しく機能していないようです。ドロップダウンは正常に動作していますが、Ajaxコールは正しく動作していません。火かき棒で見ると結果は表示されますが、ドロップダウンには表示されません。かなり混乱します。ここで

function load_notifications(view=''){ 
    $.ajax({ 
     url: "notification/new_friends.php", 
     method: "POST", 
     data:{view:"view"}, 
     dataType:"json", 
     success: function(data){ 

      $(".dropdown-menu").html(data.notification); 
if(data.unseen_notification>0){ 
    $(".badge1").html(data.unseen_notification); 
} 
    } 

    }); 
     //$(".dynamic-notification").load("notification/pm_n.php"); 
    // $(".dynamic-notification-f").load("notification/new_friends.php"); 
}; 
load_notifications(); 
$(document).on("click",".count_friend", function(){ 
    load_notifications('yes'); 
}); 
//loads every 2 seconds for chat 
setInterval(function(){load_notifications();},2000); 

はnew_friends.phpコンテンツである：

<?php 
include '../includes/dbconfig.inc.php'; 

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

if($_POST['view'] !=''){ 
$update="update friends set count='1' where friend_one=:session and count='0'"; 
$stmt=$conn->prepare($update); 
$stmt->bindValue(":session", $_SESSION['uname']); 
$stmt->execute(); 
} 
$sql123="select id from friends where friend_two=:sess_uname and count='0'"; 
$stmt123=$conn->prepare($sql123); 
$stmt123->bindValue(":sess_uname", $_SESSION['uname']); 
$stmt123->execute(); 
$request_count=$stmt123->fetchColumn(); 
//$count_friend=$stmt123->rowCount(); 
/*$sql_f_count="select *from user where user_id=:session_id and activated='1' limit 1"; 
$stmt_f_count=$conn->prepare($sql_f_count); 
$stmt_f_count->bindValue(":session_id", $_SESSION['id']); 
$stmt_f_count->execute(); 
$user_details=$stmt_f_count->fetchAll(); 
$friend_badge=$user_details[0]['friend_count_badge'];*/ 
require "notification/friend_request_notification.php"; 
// $new_friends="<span class='dropdown'><a href='#' data-placement='bottom' class='btn dropdown-toggle' data-toggle='dropdown' title='Friend Requests' data-html='true'><span class='count_friend' style=' height:33px; width:30px;'><span class='badge1 label label-pill'>".$count."</span><img src='img/logo/group-button-white.png' style='height:25px; width:27px;' alt='new_friends_alert'></span></a><ul class='dropdown-menu'></ul></span>"; 
//if($request_count[0]>0){ 
//$new_friends="<a href='#' data-placement='bottom' class='btn' data-trigger='focus' title='Friend Requests' data-toggle='popover' data-html='true' data-content='".$friend_requests."'><span class='count_friend' style=' height:33px; width:30px;'><img src='img/logo/group-button-white.png' style='height:25px; width:27px;' alt='new_friends_alert'></span><span class='badge'>".$friend_badge."</span></a>"; 
/*}else{ 
$new_friends="<a href='all_notifications.php'><img src='img/logo/group-button-black.png' style='height:25px; width:27px;' alt='new_friends_alert'></a>"; 
}*/ 
//echo $new_friends; 
//} 
$data=array(
'notification'=>$friend_requests, 
'unseen_notification' =>$request_count[0][0] 
); 

ここでjQueryのに使用されるAJAXである（ドロップダウンメニューは、ヘッダ内に配置され、セッションが初期化されている場合のみ表示されることに注意）そして、友人のためのコードが出力を要求します。ここでは

<?php 
//error_reporting(0); 
require_once 'includes/dbconfig.inc.php'; 
$sql = "select * from friends where friend_two=:session and accepted='0' order by friends_date_made asc"; 
$stmt = $conn->prepare($sql); 
$stmt->bindparam(":session", $_SESSION['uname']); 
$stmt->execute(); 
$numrows = $stmt->fetchAll(PDO::FETCH_ASSOC); 
$friend_requests=""; 
if ($numrows < 1) { 
$friend_requests = "You do not have any friend requests"; 
echo "$friend_requests"; 
exit(); 
} else { 
foreach ($numrows as $i=>$row1) { 
$reqid = $row1['friend_id']; 
$user1 = $row1['friend_one']; 
$datemade = $row1['friends_date_made']; 
$datemade1 = strftime("%B %d, %y", strtotime($datemade)); 
$sql = "SELECT * FROM user WHERE uname=:user1 LIMIT 1"; 
$stmt = $conn->prepare($sql); 
$stmt->bindparam(":user1", $user1); 
$stmt->execute(); 
$thumbrow = $stmt->fetchAll(PDO::FETCH_ASSOC); 
$user1avatar = $thumbrow[$i]['avatar']; 
$user1id=$thumbrow[$i]['user_id']; 

if ($user1avatar =="") { 
$user1pic = '<img src="img/avatardefault.png" height="50" style="float:left;" width="50" alt="'.$user1.'" class="user_pic">'; 
} else { 
$user1pic = '<img src="../user/user/'.$user1id.'/'.$user1avatar.'" height="50" style="float:left;" width="50" alt="'.$user1.'" class="user_pic">'; 

} 
$friend_requests .= '<li><div id="'.$reqid.'" float="right" class="friendrequests"> 
<a href="home.php?u='.$user1.'">'. $user1pic .'</a> 
<div class="user_info '.$reqid.'" id="'.$reqid.'"><small>' . $datemade1 . '</small> 
<a href="home.php?u='.$user1.'">'.$user1.'</a> is requesting your friendship<br /><br /> 
<button id="'.$reqid.'" name="'.$_SESSION['uname'].'" sess="'.$_SESSION['id'].'" class="accept_btn btn btn-warning">Accept</button><span class="show-spinner"></span> or 
<button id="'.$reqid.'" name="'.$_SESSION['uname'].'" sess="'.$_SESSION['id'].'" class="reject_btn btn btn-warning">Reject</button> 
</div> 
</div><hr></li>'; 


} 

}

はあなたが助けることができる場合は、移入ドロップダウンです：

<?php 
// Assume $db is a PDO object 

$dbh = new PDO('mysql:host=localhost;dbname=populatedropdown', "root", ""); 

$query = $dbh->query("select * from position"); // Run your query 

echo '<form action="populate.php" method="get">'; 
echo '<select name="populate">'; // Open your drop down box 



// Loop through the query results, outputing the options one by one 
while ($row = $query->fetch(PDO::FETCH_ASSOC)) { 
    echo '<option value="'.$row['id'].'">'.$row['name'].'</option>'; 
} 

echo '</select>';// Close your drop down box 


echo '<input type="submit" name="edit" value="Edit">'; 

echo '</form>'; 
?>
