Php 从包含运行的SQL表单在firefox/safari中不起作用

** 这是保存为php Include的多个表单之一的代码，可在同一管理页面上使用。它们可以在所有浏览器中单独工作，但不能在safari或firefox的管理页面中工作。有什么想法吗？ 谢谢你的帮助！ （我知道我需要切换到准备好的报表）**

<?php
$servername = "1.1.1.1:111";
$username = "root";
$password = "root";
$dbname = "sit";
// Create connection
$conn = new mysqli($servername, $username, $password,$dbname);

if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
$result = mysqli_query($conn, "SELECT * FROM `calltoaction` ");
$values = mysqli_fetch_array($result);

$calltoaction_title = $_POST['calltoaction_title'];
$calltoaction_content = $_POST['calltoaction_content'];

if(isset($_POST['calltoaction_title'])){

$calltoaction= "UPDATE calltoaction SET calltoaction_title='$calltoaction_title' ,calltoaction_content='$calltoaction_content' WHERE  calltoaction_id='1'";

if (mysqli_query($conn, $calltoaction)) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . mysqli_error($conn);
}   


}

?>

<form id="comment_form" method="post" action="<?php $calltoaction?>" onsubmit="setTimeout(function () { window.location.reload(); }, 10), location.reload(true);">
 <table width="100%" border="0" cellspacing="1" cellpadding="2">
