php-“组”列以某种方式导致语法错误

我不断收到此错误：

You have an error in your sql Syntax; check the manual that corresponds to your MySQL server version for the right Syntax to use near ‘…’ at line 1.

我知道“组”字段有问题,因为如果删除它,我的表将得到更新而不会出现任何问题.

这是我的表单代码：

<form enctype="multipart/form-data" action="products_import_confirmation.PHP" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="99999999" />
<center><table><br><br>
<td>Prekės pavadinimas:     
<td><input type="text" name="name_p" value="<?PHP echo $name_p;?>">
<span class="error">* <?PHP echo $name_pErr;?></span></td>
<tr>
<td>Gamintojas:<td><input type="text" name="brand" value="<?PHP echo $brand;?>">
<span class="error">* <?PHP echo $brandErr;?></span></td>
<tr>
<td>Specifikacijos:<td><textarea style="resize:none" name="specs" rows="5" cols="60"><?PHP echo $specs;?></textarea>
<span class="error">* <?PHP echo $specsErr;?></span></td>
<tr>
<td>Aprašymas:<td><textarea style="resize:none" name="about" rows="5" cols="60"><?PHP echo $about;?></textarea>
<tr>
<td>Kategorija:<td><select name="group" value="<?PHP echo $group;?>">
<option value="">Pasirinkite kategoriją</option>
<option disabled>------------------</option>
<option value="Telefonai">Telefonai</option>
<option value="Planšetės">Planšetės</option>
<option value="Kompiuteriai">Kompiuteriai</option>
</select>
<span class="error">* <?PHP echo $groupErr;?></span></td>
<td><div><input name="image" accept="image/jpeg" type="file" /></div></td>
<tr>
</center></table>                               
<td><div><input type="submit" value="Submit" /></div></td>
</form>

这是我对MysqL代码的更新：

<?PHP
require("/includes/connection_to_db.PHP");

MysqL_query("SET NAMES 'utf8'"); 

session_start();
echo "<Meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\"/>";

if(isset($_GET['logout']) && $_GET['logout'] == "true"){
unset($_SESSION['user_id']);
header("Location: index.PHP");
}
if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) 
    {
        // Temporary file name_p stored on the server
        $tmpname_p = $_FILES['image']['tmp_name'];

        // Read the file
        $fp = fopen($tmpname_p, 'r');
        $image = fread($fp, filesize($tmpname_p));
        $image = addslashes($image);
        fclose($fp);

        date_default_timezone_set('Europe/Vilnius');
        $V_ID = MysqL_real_escape_string($_SESSION['user_id']);
        $name_p = MysqL_real_escape_string($_POST['name_p']);
        $group = MysqL_real_escape_string($_POST['group']);
        $brand = MysqL_real_escape_string($_POST['brand']);
        $specs = MysqL_real_escape_string($_POST['specs']);
        $about = MysqL_real_escape_string($_POST['about']);
        $date = date('Y-m-d H:i:s'); 

        $query = "INSERT INTO prekės (V_ID, name, group, brand, specs, about, image, date)
                VALUES ($V_ID, '$name_p', $group, '$brand', '$specs', '$about', '$image', '$date')";

        if(MysqL_query($query))
        {

            echo "Prekė ".$name." sėkmingai įkelta <br>";
            echo "<a href=\"../main.PHP\">Grįžti</a>";
        }
        else
        {

            echo "Įvyko klaida: ".MysqL_error()."<br>";
            echo "<a href=\"../products_import.PHP\">Grįžti</a>";
            echo $date;
            echo $name_p;
            echo $brand;
            echo $specs;
            echo $about;
            echo $group;
        }
    }
    else 
    {
        echo "Neužpildyti visi reikalaujami duomenys.";
    }

MysqL_close();
?>

如您所见,我做了一些回显,以检查是否获得了数据,并且一切正常. “分组”数据只会使事情变糟.有任何想法吗？

解决方法:

group是一个保留关键字,它用于查询.

您需要对保留字使用backtics作为

`group`

在这里检查他们的名单
