Question

有什么想法吗？我已经花了几个小时在看这个，看不到它。连接很好。

var height = 200;
var width  = 200;

canvas.width  = width;
canvas.height = height;

var ctx = canvas.getContext('2d');

ctx.strokeStyle = '#090';
ctx.beginPath();
ctx.arc(width/2, height/2, width/2 - width/10, 0, Math.PI*2);
ctx.stroke();

canvas.toBlob(function (blob) {
  //consider blob is your file object

  var reader = new FileReader();

  reader.onload = function () {
    console.log(reader.result);
  }

  reader.readAsBinaryString(blob);
});

输出：

$DB = new mysqli("127.0.0.1", "Account Here", "Password Here", "DB Here", "Port");  
$query = $DB->prepare("INSERT INTO `Users`(`FirstName`, `LastName`, `Email`, `UserName`, `UserNameHash`, `PasswordHash`, `PasswordSalt`) VALUES (?, ?, ?, ?, ?, ?, ?)"); 
$query->bind_param("sssssss", $FirstName, $LastName, $Email, $Username, $EUsername, $EPassword, $Salt); 
if($query->execute()){
        echo "executed <BR />";
}else{
        echo "Failed <BR />";
}
$query->close();
mysqli_close($DB);
echo "complete";

已建议我启用已启用的错误，并删除If语句，这是我这样做时的输出：

Failed
Complete

mysqli insert with bind_param静默失败（$ query-> execute（）返回false
