Question

好吧我正在尝试上传图片，然后是图片说明。图像将上载到数据库，但文本字段不会。

我认为我的代码是正确的，但由于某种原因，没有任何内容会进入数据库。我认为什么都没有存入阵列，我不知道为什么。

这是我的表格。

<form method="post" enctype="multipart/form-data" action="process.php">
<div id="filediv">
<div id="imagefiles">
<input type="hidden" name="MAX_FILE_SIZE" value="2000000">
<label>Upload File:
<input name="userfile[]" type="file" id="userfile" multiple></label>
<label>Item Name: <input name='itemname[]' type="text"></label>
<label>Item Description: <input name="itemdesc[]" type="text"></label>
<label>Item Timeframe: <input name='itemtime[]' type="text"></label>
<label>Item Donor: <input name='itemdonor[]' type="text"></label>
<label>Hidden Information: <input name='hidden[]' type="text"></label>
 </div>
 </div>
<br>

<input type="button" id ="thebutton" value="Add Another File" />
<input name="UploadFile" type="submit" />
</form>

这是我的功能

function uploadFile()
{
include 'functions.php';
hasSession();
session_start();
$dbhost =   '';
$dblogin = '';
$dbpass = '!';
$dbbase = '';
$conn = mysqli_connect($dbhost, $dblogin, $dbpass, $dbbase);
if(mysqli_connect_errno()){
    printf("Can't connect to MySQL Server. Errorcode: %s\n", mysqli_connect_error()); 
    exit; 
} 
$arrCount = count($_POST["itemname"]);

$name[] = $_POST["itemname"];
$donor[] = $_POST["itemdonor"];
$desc[] = $_POST["itemdesc"];
$time[] = $_POST["itemtime"];
$hide[] = $_POST["hidden"];

for($i=0; $i<$arrCount; $i++){
    $sql = "INSERT into items (name, donor, time, desc, hidden) VALUES ('$name[$i]', '$donor[$i]', '$desc[$i]', '$time[$i]', $hide[$i]')";
}
$numFiles = count($_FILES['userfile']['name']);
for($x=0;$x<$numFiles;$x++){
//($_FILES['userfile'][$counter]['error'] == 0) && 
    if (($_FILES['userfile']['size'][$x] > 0)){

Answer 1

desc是一个保留字，需要用反引号括起来。

http://dev.mysql.com/doc/refman/5.5/en/reserved-words.html

如：

`desc`

$sql = "INSERT into items (name, donor, time, `desc`, hidden) VALUES ('$name[$i]', '$donor[$i]', '$desc[$i]', '$time[$i]', $hide[$i]')";

正如MonkeyZeus所述，并且即将编写相同的注释（在同一时间），最好用反引号包装表名和列。

例如：

$sql = "INSERT into `items` (`name`, `donor`, `time`, `desc`, `hidden`) VALUES ('$name[$i]', '$donor[$i]', '$desc[$i]', '$time[$i]', $hide[$i]')";

编辑：

我注意到

缺少引用

  '$time[$i]', $hide[$i]'

- - - - - - - - - - - - - ^

更改为：

'$time[$i]', '$hide[$i]'

完整的代码：

$sql = "INSERT into `items` (`name`, `donor`, `time`, `desc`, `hidden`) VALUES ('$name[$i]', '$donor[$i]', '$desc[$i]', '$time[$i]', '$hide[$i]')";

Answer 2

我建议你更改desc列，因为desc是一个为命令保留的mysql字，它的应用程序将是：

    SELECT * FROM my_table ORDER BY id DESC

因此您不能将desc用作列名。要获得有关此类错误的信息，请使用

    mysql_error()

每次查询后都有

功能，即

    mysql_query($sql) or die(mysql_error())

因此，将该列名从 desc 更改为另一个不是mysql保留字的名称。祝你好运！
