Question

我尝试过varchar（5000），text，mediumtext，longtext但都徒劳无功。如果我从phpmyadmin添加数据，它会成功添加，但是通过查询，只有当数据少于200个字符时才会添加，如果数据超过200个字符，整个查询将无法执行。

我的代码中没有任何错误。

$newsTitle = $_POST['newsTitle'];
$newsType = $_POST['newsType'];
$newsDescription = $_POST['newsDescription'];

$target_dir = "../images/news/".$newsType."/";
$target_file = $target_dir .$adminId.rand(5,100)."_". basename($_FILES["newsImage"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["newsImage"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["newsImage"]["size"] > 5000000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["newsImage"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["newsImage"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

$newsImage = $target_file;

$datetime = date("Y-m-d H:i:s");



mysqli_query($conn, "INSERT INTO `news`(`addedBy`, `title`, `type`, `description`, `image`, `datetime`, `comments`, `views`)
VALUES ($adminId,'$newsTitle','$newsType','".$_POST['newsDescription']."','$newsImage','$datetime',0,0)");
