php - 图片无法在 PHP 中上传

Question

我正在使用以下 php 代码上传图片，但文件未上传。

if(isset($_POST['submit'])){
    $title = $_POST['title'];

    $target_folder = "../newsimageuploads/";
    $bannerimagelink = "http://example.com/newsimageuploads";

    $bannerimage = addslashes(file_get_contents($_FILES['bannerimage']['tmp_name']));
    $bannerimage_name = addslashes($_FILES['bannerimage']['name']);
    $bannerimage_size = getimagesize($_FILES['bannerimage']['tmp_name']);

    if ($bannerimage!=""){

    $rand = rand(111111, 9999999);
    $fname =  $_FILES["bannerimage"]["name"];
    $newname = "Image ".$rand.".png";

    move_uploaded_file($_FILES["bannerimage"]["tmp_name"], $target_folder.$newname);
    $bannerimage_location = $bannerimagelink."/".$newname;
    } 

    $query =mysql_query("INSERT INTO mytable (title,image) VALUES ('$title','$bannerimage_location')")or die(mysql_error());
    if (($query) === TRUE) {
    echo "<p style='color:green;'>Added Successfully</p>";
    } else {
    echo "Some Error Occured :(";
    }
}

我的 HTML 部分是

<form action="#" method="post">
    <input type="text" name="title">
    <input type="file" name="bannerimage" accept="image/jpeg,image/png,image/gif">
    <button type="submit" name="submit">Add</button>
</form>

我的标题正在插入到 MySQL 表中，但图像没有。

您的表单中缺少 enctype='multipart/form-data'

<form action="#" method="post" enctype="multipart/form-data">
