我试图以某种形式保存用户填写的数据。
问题是,当我按下提交按钮时,所有数据都按照我想要的方式保存,但它会多次保存。 (多行中的相同数据)
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST'){
$share = $_POST['share'];
$date = $_POST['date'];
$dealtype = $_POST['dealtype'];
$enter = $_POST['enter'];
$exitdeal = $_POST['exitdeal'];
$no1 = $_POST['no1'];
$no2 = $_POST['no2'];
$profit = $_POST['profit'];
if ($share != "")
{
if ($date != "")
{
if ($dealtype != "" )
{
if ($enter != "" )
{
if ($exitdeal != "" )
{
$mysql = "INSERT INTO markettable (share, date, dealtype, enter, exitdeal, no1, no2, profit)
VALUES ('$share','$date', '$dealtype', '$enter', '$exitdeal', '$no1', '$no2', '$profit')";
}
}
}
}
}
$mysqli->query($mysql);
if ($mysqli->query($mysql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $mysql . "<br>" . $mysqli->error;
}
$mysqli->close();
}
?>

看这里,
$mysqli->query($mysql);
if ($mysqli->query($mysql) === TRUE) {
echo "New record created successfully";
}
$mysqli->query($mysql);
首先插入数据,再次插入if ($mysqli->query($mysql) === TRUE)
。
您将代码更改为
$result = $mysqli->query($mysql); // save the result in $result variable
if ($result === TRUE) { // checks if its successfully inserted
echo "New record created successfully";
}

您调用查询执行两次,第一次执行if语句,第二次调用if语句条件。
