Question

我想创建一个消息传递系统，这里是它的php代码 SQLite version 3.15.1 2016-11-04 12:08:49 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite> create table x(timestamp real); sqlite> insert into x values (2.75); sqlite> insert into x values(35065); sqlite> select * from x; 2.75 35065.0 sqlite> select strftime('%J', '1899-12-30'); -- base time as a Julian Day Number 2415018.5 sqlite> select datetime(timestamp+2415018.5) from x; 1900-01-01 18:00:00 1996-01-01 00:00:00 select cast(strftime('%m', timestamp+2415018.5) as integer), cast(strftime('%d', timestamp+2415018.5) as integer) from x; 1|1 1|1 sqlite>

<?php
$connect= new mysqli('localhost', 'root','' ,'user');



if($connect->connect_error){

    die('connection failed bruh');

} else 

echo 'connected';

$message= $_POST('message');
$name= $_POST('name');

$sql = "INSERT message into user WHERE name=$name AND message=$message  ";

$result = $connect-> query($sql);

if ($result-> num_rows > 1 ){
 while ($result->fetch_assoc()){
    echo  $row["$message"];
}

} else {
echo    'some error';
}


?>

并且html是

<?php
$connect= new mysqli('localhost', 'root','' ,'user');



if($connect->connect_error){

    die('connection failed bruh');

} else 

echo 'connected';

$message= $_POST('message');
$name= $_POST('name');

$sql = "INSERT message into user WHERE name=$name AND message=$message  ";

$result = $connect-> query($sql);

if ($result-> num_rows > 1 ){
 while ($result->fetch_assoc()){
    echo  $row["$message"];
}

} else {
echo    'some error';
}


?>

我得到了致命错误：

我遇到此错误，如果有人认为此代码有更多错误，请告诉我我使用了大括号，但它仍然无法正常工作

Answer 1

您需要使用方括号来访问$_POST的数组属性：

$message= $_POST['message'];
$name= $_POST['name'];

Answer 2

你必须遇到主要错误：

1

html>
<head>
    <title>Square Stairs™</title>
</head>
<body bgcolor="#000">
 <canvas id="canvas" style="border:3px solid #fff"></canvas>
</body>
</html>

2

 $message= $_POST['message'];
 $name= $_POST['name'];

致命错误：数组回调必须包含索引0和1
