有人可以帮我填写这个表格吗？ 我有一个包含 3 个 INT 列(danni、lenni、anders)的表。我希望此表单插入一个新行，其中包含我每次使用时在字段中写入的数字。它确实插入了一个新行，但无论我输入什么数字，它都只会在表中插入“0”。
<?php
// Connection
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
// Escape user inputs for security
$danni = mysqli_real_escape_string($link, $_REQUEST['danni']);
$lenni = mysqli_real_escape_string($link, $_REQUEST['lenni']);
$anders = mysqli_real_escape_string($link, $_REQUEST['anders']);
// attempt insert query execution
$sql = "INSERT INTO ligabs3 (danni, lenni, anders) VALUES ('$danni', '$lenni', '$anders')";
if(mysqli_query($link, $sql)){
echo "Records added successfully.";
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
// close connection
mysqli_close($link);
?>

最佳答案
there are so many errors in your code. when you refresh page code will execute and insert in database. not after submit form. everytime on page refresh it will insert.
name is compulsory for submit button.
try this.
<?php
if($_POST['addrecord']){
// Connection
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
// Escape user inputs for security
$danni = mysqli_real_escape_string($link, $_REQUEST['danni']);
$lenni = mysqli_real_escape_string($link, $_REQUEST['lenni']);
$anders = mysqli_real_escape_string($link, $_REQUEST['anders']);
// attempt insert query execution
$sql = "INSERT INTO ligabs3 (danni, lenni, anders) VALUES ('$danni', '$lenni', '$anders')";
if(mysqli_query($link, $sql)){
echo "Records added successfully.";
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
// close connection
mysqli_close($link);
}
?>
