<script src="webscript.js"></script>

	<!-- First, include the Webcam.js JavaScript Library -->
	<script type="text/javascript" src="webcam.min.js"></script>
	<script type="text/javascript" src="script.js"></script>
	
	<!-- Configure a few settings and attach camera -->
	<script language="JavaScript">
		Webcam.set({
			width: 320,
			height: 240,
			image_format: 'jpeg',
			jpeg_quality: 90
		});
		Webcam.attach( '#my_camera' );
		
		var shutter = new Audio();
		shutter.autoplay = false;
		shutter.src = navigator.userAgent.match(/Firefox/) ? 'shutter.ogg' : 'shutter.mp3';
		
		function take_snapshot() {
			// take snapshot and get image data
			Webcam.snap( function(data_uri) {
				// display results in page
				document.getElementById('results').innerHTML = 
					'<h2>Here is your image:</h2>' + 
					'<img src="'+data_uri+'"/>';
                                Webcam.upload( data_uri, 'upload.php', function(code, text) {
                                           alert(data_uri);
                                });
			} );
		}
		
	</script>

<?php
include 'connection.php';  

    // be aware of file / directory permissions on your server
    $newname = move_uploaded_file($_FILES['webcam']['tmp_name'], 'uploads/webcam'.date('YmdHis').rand(383,1000).'.jpg');
    $query = "INSERT INTO entry(name) VALUES('".$_GET['url']."')";
    mysql_query($query)or die(mysql_error());
	echo "<script>alert('successfully..');</script>";

?>

【问题讨论】：

是来自 php 的 $dis, $limit 变量吗？是的然后" SELECT * FROM bed limit ". $dis.",". $limit . "
@lemon 你的第二句话无关紧要，看看stackoverflow.com/questions/3446216/…

【解决方案1】：

假设$mysqli 是一个成功连接的[new Mysqli] 对象。

$query = "SELECT * FROM 'database.table' WHERE 'somecolumn'='someval' LIMIT= 5";

if ($stmt = $mysqli->prepare($query)) {

/* execute statement */
$stmt->execute();

/* bind result variables */
$stmt->bind_result($name, $code);

/* fetch values */
while ($stmt->fetch()) {
    printf ("%s (%s)\n", $name, $code);
}

/* close statement */
$stmt->close();
