我试图在我创建的网站上创建销售(想想易趣),用户输入所有输入详细信息以创建可销售商品,点击按钮和所有信息插入进入db表' sellitems'使用准备好的声明,现在我遇到的问题是我试图从表(用户)中获取用户位置(State& Suburb)详细信息,并将其插入到准备好的语句中,这些语句全部进入&#34 ; sellingitems"在sellitems表中使用SaleState,SaleSuburb,我得到的错误是
"致命错误:声明失败!您的SQL语法有错误;检查与您的MySQL服务器版本相对应的手册,以获得正确的语法,以便在' INSERT INTO sellitems(ItemID,UserID,CatID,ItemName,ItemDesc,ItemAmount,'在"第2行; / p>
我希望这是清楚易懂的,我已经研究了很多时间,并且无法通过加入或其他方式帮助我找到INSERT上的任何内容,请询问我是否需要澄清任何内容并提前感谢您的帮助! !
$stmt = mysqli_prepare($conn, "INSERT INTO sellingitems (ItemID, UserID, CatID, ItemName, ItemDesc, ItemAmount, TimeFrame, ItemCond, Postage, Returns, SaleState, SaleSuburb)
SELECT State, Suburb FROM user WHERE UserID = '$UID'
VALUES ('',?,'',?,?,?, CURRENT_TIMESTAMP,?,?,?,State,Suburb)");
if ($stmt === false) {
trigger_error('Statement failed! ' . htmlspecialchars(mysqli_error($conn)), E_USER_ERROR);
}
$bind = mysqli_stmt_bind_param($stmt, 'issdsssss', $UID, $ItemName, $ItemDesc, $Amount, $ItemCond, $Postage, $Returns);
if ($bind === false) {
trigger_error('Bind param failed!', E_USER_ERROR);
}
$exec = mysqli_stmt_execute($stmt);
if ($exec === false) {
trigger_error('Statement execute failed! ' . htmlspecialchars(mysqli_stmt_error($stmt)), E_USER_ERROR);
}
if ($stmt == false) {
$response = "Sorry something went wrong. : ";
print_r($response);
print_r($stmt->mysqli_error);
print_r($stmt->error);
return;
} else {
$response = "Sale Created.";
print_r($response);
}
答案 0 :(得分:0)
这不是INSERT SELECT的正确语法。 See the documentation
请改为尝试:
$stmt = mysqli_prepare($conn, "INSERT INTO sellingitems (ItemID, UserID, CatID, ItemName, ItemDesc, ItemAmount, TimeFrame, ItemCond, Postage, Returns, SaleState, SaleSuburb)
SELECT '',?,'',?,?,?, NOW(),?,?,?,State,Suburb FROM user WHERE UserID = '$UID'");
更好的是将两个语句分开,如下所示:
$result = mysqli_query($conn, "SELECT State, Suburb FROM user WHERE UserID = '$UID'");
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);
$stmt = mysqli_prepare(
$conn,
"INSERT INTO sellingitems (
ItemID,
UserID,
CatID,
ItemName,
ItemDesc,
ItemAmount,
TimeFrame,
ItemCond,
Postage,
Returns,
SaleState,
SaleSuburb)
VALUES
('', ?, '', ?, ?, ?, NOW(), ?, ?, ?, '{$row['State']}', '{$row['Suburb']}')"
);
