 <script type="text/javascript">
        $(document).ready(function(){

        });
        function sendPushNotification(id){
            var data = $('form#'+id).serialize();
            $('form#'+id).unbind('submit');                
            $.ajax({

 <body>
    <?php
    include_once 'db_functions.php';
    $db = new DB_Functions();
    $users = $db->getAllUsers();
    if ($users != false)
        $no_of_users = mysql_num_rows($users);
    else
        $no_of_users = 0;
    ?>
    <div class="container">

                </li>
            <?php } ?>
        </ul>
    </div>
</body>

在上面的代码中，我们向java脚本发送一个id并发送msg ..

因此希望将ID的列表发送到JAVASCRIPT函数并在javascript函数中打印这些值。

不，我不需要整个表格..

但我想使用一个表单，一个提交按钮＆amp;一个文本字段发送到多个设备。

感谢提前......

这是我们接受消息的表单屏幕

<html> 
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js">
</script> 
<script type="text/javascript"> $(document).ready(function(){ });
</script> 
</head> 
<body> 
<form name="puski" method="post" action="send_message.php">
<input type="text" name="message"/>
<input type="submit" value="Submit"/> 
</form>
</body> 
</html>

这是读取所有ID并将消息发送到GCM.php的文件

<?php if (isset($_POST["message"])) {
 $message = $_POST["message"]; 
 include_once './GCM.php'; 
 $gcm = new GCM();
 include_once 'db_functions.php';
 $db = new DB_Functions();
 $users = $db->getAllUsers(); 
 while ($row = mysql_fetch_array($users)) { 
  $gcm_array[]=$row['gcm_regid'];
 } 
 $message = array("price" => $message);
 $result = $gcm->send_notification($gcm_array, $message); 
 echo $result;

}？＆gt;

我们有GCM.php

<?php

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

/**
 * Description of GCM
 *
 * @author Ravi Tamada
 */
class GCM {

//put your code here
// constructor
function __construct() {

}

/**
 * Sending Push Notification
 */
public function send_notification($registatoin_ids, $message) {
    // include config
    include_once './config.php';

    // Set POST variables
    $url = 'https://android.googleapis.com/gcm/send';

    $fields = array(
        'registration_ids' => $registatoin_ids,
        'data' => $message,
    );

    $headers = array(
        'Authorization: key=' . GOOGLE_API_KEY,
        'Content-Type: application/json'
    );
    // Open connection
    $ch = curl_init();

    // Set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Disabling SSL Certificate support temporarly
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    // Execute post
    $result = curl_exec($ch);
    if ($result === FALSE) {
        die('Curl failed: ' . curl_error($ch));
    }

    // Close connection
    curl_close($ch);
    echo $result;
}

}

?>

我们仍然收到错误

Fatal error: Call to undefined function curl_init() in C:\wamp\www\gcm_server_php\GCM.php on line 41

请帮忙

步骤1：创建一个php页面，您可以在其中输入需要为所有用户发送的消息

message.php

html>
<head>
    <link rel="stylesheet" type="text/css" href="design.css"/>
</head>

<body>
    <div id="container">
        <h6>GCM</h6>
        <h3>MESSAGE</h3>
        <form action="notification.php" method="post">

            <textarea id="message" name="msg" rows="6" cols="41" autofocus="true"></textarea>
            <br />
            <br />
            <input type="submit" class="btn_class" value="Send"/>

        </form>
    </div>

</body>

design.css

div#container{
position:absolute;
width:400px;
height:350px;
top:50%;
left:50%;
margin-top:-225px;
margin-left:-200px;
box-shadow: 0 0 5px rgba(0, 0, 0, 0.35);
}

#message{
margin-left:25px;
}

.btn_class{
color:blue;
margin-left:170px;
}

h6{
text-align:center;
font-family:sans-serif;
font-size:20px;
}

h3{
margin-left:30px;
font-family:sans-serif;
font-size:14px;
}

步骤2：创建notification.php文件，收到消息后，将使用您的api密钥和注册表将其发送给所有用户

notification.php

<?php

    $message=$_POST["msg"];
            ........
            // construct sql query for database access

            while($row=mysql_fetch_array($result)){

                   $registrationIDs[] = $row["gcm_regid"]; // store all reg ids from the column "gcm_regid" in the array
            }

            $fields = array(
                   'registration_ids' => $registrationIDs,
                   'data' => array( "message" => $message ),
             );
?>

推送通知一次发送到id的数组
