Question

我正在学习面向对象编程的PHP，并希望帮助我在数据库中插入图像。我该怎么办？

通常情况下，数据插入时没有图像，但不能随图像一起输入数据。因此，请解决此问题。

protected function create()
{
    $this->validate();
    if (!empty($this->errors)) {
        return false;
    }
    $attributes = $this->sanitized_attributes();
    $sql = "INSERT INTO " . static::$table_name . " (";
    $sql .= join(', ', array_keys($attributes));
    $sql .= ") VALUES ('";
    $sql .= join("', '", array_values($attributes));
    $sql .= "')";
    $result = self::$database->query($sql);
    if ($result) {
        $this->id = self::$database->insert_id;
    }
    return $result;
}

插入数据时没有插入图像，但尝试插入带有图像的数据，请帮助我

尝试一下

<html>
<body>
<?php
$msg = '';
if($_SERVER['REQUEST_METHOD']=='POST'){
    $image = $_FILES['image']['tmp_name'];
    $img = file_get_contents($image);
    $con = mysqli_connect('localhost','root','','admin') or die('Unable To connect');
    $sql = "insert into images (image) values(?)";

    $stmt = mysqli_prepare($con,$sql);

    mysqli_stmt_bind_param($stmt, "s",$img);
    mysqli_stmt_execute($stmt);

    $check = mysqli_stmt_affected_rows($stmt);
    if($check==1){
        $msg = 'Image Successfullly UPloaded';
    }else{
        $msg = 'Error uploading image';
    }
    mysqli_close($con);
}
?>
<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="image" />
    <button>Upload</button>
</form>
<?php
    echo $msg;
?>
</body>
</html>
