[英]php INSERT data to sql in for loop
我想在for循環中創建一個mysql插入語句。 I'm looking for to insert multiple records at a time.
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$label =htmlspecialchars( $_POST["label"]);
$splitLabel = explode(" ", $label);//split the label to a array
}
//.....insert another data, getting the $last_id here
$sql = $result = "";
for ($i =0; $i< count($splitLabel); $i++){
if ($i < count($splitLabel)){
$sql .= "INSERT INTO label (item_id, label)
VALUES ('".$last_id."', '".$splitLabel[$i]."');";
}else{
$sql .= "INSERT INTO label (item_id, label)
VALUES ('".$last_id."', '".$splitLabel[$i]."')";
}
}
$result = mysqli_query($conn, $sql);
我有一個錯誤
check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO label (item_id, label)
VALUES ('13', 'tin');INSERT INTO label (' at line 2
標簽表:
Field Type null
item_id int(11) NO
label varchar(50) NO
我找不到錯誤,請幫我找到它..
mysqli_query()只提供一個語句,但是你發送了多個語句。 你可以使用mysqli_multi_query() ,但....
更好地使用准備好的語句+參數 。
像是這樣的東西
if ( isset($_POST["label"]) ) {
$stmt = $conn->prepare('INSERT INTO label (item_id, label) VALUES (?,?)')
if ( !$stmt ) {
someErrorHandler( $conn->error );
}
else if ( !$stmt->bind_param('ss', $last_id, $label) ) {
someErrorHandler( $stmt->error );
}
else {
// I have no idea where this $last_id comes from ....
foreach( explode(' ', $_POST["label"]) as $label ) {
if ( !$stmt->execute() ) {
someErrorHandler( $stmt->error );
}
}
}
}
您只需要使用mysqli_multi_query()
進行多個查詢。
$sql = "";
$result = "";
for ($i =0; $i< count($splitLabel); $i++){
if ($i < count($splitLabel)){
$sql .= " INSERT INTO label (item_id, label)
VALUES ('".$last_id."', '".$splitLabel[$i]."');";
}else{
$sql .= " INSERT INTO label (item_id, label)
VALUES ('".$last_id."', '".$splitLabel[$i]."');";
}
}
$result = mysqli_multi_query($conn, $sql);
對於此操作,您不能將多個INSERT用於單個mysqli_query
,您可以使用mysqli_multi_query()
來執行多個查詢。
對於多個查詢執行,您可以使用mysqli_multi_query()
INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);
所以你可以試試
$sqlInsert = '';
$countOfData = count($splitLabel);
for ($i = 0; $i < $countOfData; $i++){
$sqlInsert .= "('{$last_id}', '{$splitLabel[$i]}'),";
}
$sqlInsert = rtrim($sqlInsert, ',');//remove the extra comma
if ($sqlInsert) {
$sql = "INSERT INTO label (item_id, label) VALUES {$sqlInsert} ;";
$result = mysqli_query($conn, $sql);
}
試試這個代碼
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$label =htmlspecialchars( $_POST["label"]);
$splitLabel = explode(" ", $label);//split the label to a array
}
//.....insert another data, getting the $last_id here
$sql = $result = "";
for ($i =0; $i< count($splitLabel); $i++){
if ($i < count($splitLabel)){
$sql .= "INSERT INTO label (item_id, label) VALUES ('$last_id', '$splitLabel[$i]')";
}else{
$sql .= "INSERT INTO label (item_id, label)
VALUES ('$last_id', '$splitLabel[$i]')";
}
}
$sql .= "INSERT INTO label (item_id, label)
VALUES ('".$last_id."', '".$splitLabel[$i]."');";
你錯過了 ”;”
試試這個吧。
$sql = $result = "INSERT INTO label (item_id, label) VALUES ";
for ($i =0; $i< count($splitLabel); $i++){
$sql .= "('".$last_id."', '".$splitLabel[$i]."')";
if ($i < count($splitLabel) - 1){
sql .= ",";
}
}
