我的表单有一个问题，用于将数据插入表中，如果数据插入正确与否，我需要它来显示消息。顺便说一句，实际的代码没有向表中插入任何东西，但如果我直接使用用于插入它的php文件，它就可以了。 这是包含表单和脚本的文件： registrarrack.php
<?php
include('conexion.php');
session_start();
?>

<head>
<title>Inicio</title>

<script src="js/jquery-1.12.4.js"></script>
<script> function myFunction() {
document.getElementsByClassName("topnav")[0].classList.toggle("responsive");
}
function justNumbers(e)
{
var keynum = window.event ? window.event.keyCode : e.which;
if ((keynum == 8))
return true;
return /\d/.test(String.fromCharCode(keynum));
}
function showContent() {
element = document.getElementById("content");
check = document.getElementById("check");
if (check.checked) {
element.style.display='block';
}
else {
element.style.display='none';
}
}
</script>
</head>

if($cons=mysqli_fetch_array($consulta)){
echo '<span>Error: rack is already registered</span>';
}else{
$sql2="INSERT INTO rack (NoSerie, WO, Familia, Locacion, Tecnico) VALUES ('$NoSerie','$WO' ,'$Familia','$Locacion','$Tecnico')";

我不知道代码有什么问题，希望你能帮帮我。抱歉我的英文不好
