Question

我需要创建一个可以检查填充的表单;如果为true，则在单击“提交”按钮后自行刷新 viewing.php帖子最早在提交时显示，时间戳按降序排列我已将此连接到本地数据库以存储和显示输入的数据。

我已尝试过论坛和youtube中的所有代码，但没有任何效果。

以下是代码：

的index.php：

<style rel="stylesheet" type="text/css">
    body {
        left:20px;
        font-size:15pt;
    }
    label, input, textarea{
        left:20px;
        margin:5px 5px 5px 5px;
        font-size:15pt;
    }
    div {
        width:50%;
        background-color:lightgrey;
    }
</style>
</head>

<body>    
<div> <!--id="auto"-->
    <form  name="ajax" action="insert.php" method="post" id="contact">
        <br>
    <label>Please Enter Your Comments :</label>
        <br><br>
    <label>Name :<span>*</span>
    <input type="text" name="Name" id="Name" value="" placeholder="Name" autocomplete="off"/>
    </label>
        <br>
    <label>Enter Your Wishes : <span>*</span>
        <br>
    <textarea name="Comment" rows="10" cols="30" id="Comment" placeholder="Message" autocomplete="off"></textarea>
    </label>
        <br>
    <input type="submit" value="Submit" onclick="aa();"/>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    <input type="reset" value="Clear"/>

    </form>
</div>

<script type="text/javascript">
    location.refresh(true);

    $('#contact').submit(function () {
        sendContactForm();
    return false;
    });
</script>
</body>
</html>

insert.php：

<?php

session_start();

require 'config.php';

if(isset($_POST['Name'], $_POST['Comment'])){
    $fields = [
        'Name' => $_POST['Name'],
        'Comment' => $_POST['Comment']
    ];

    foreach ($fields as $field => $data) {
        if (empty($data)){
            $errors[] = 'The '.$field . ' field is required.';
        }
    }
}
else {
    $errors[] = 'Error.';
}

// This function will run within each post array including multi-dimensional arrays 
function ExtendedAddslash(&$params)
{ 
    foreach ($params as &$var) {
        // check if $var is an array. If yes, it will start another ExtendedAddslash() function to loop to each key inside.
        is_array($var) ? ExtendedAddslash($var) : $var=addslashes($var);
        unset($var);
    }
} 

// Initialize ExtendedAddslash() function for every $_POST variable
ExtendedAddslash($_POST); 

$ID = $_POST['ID'];
$Name = $_POST['Name'];
$Comment = $_POST['Comment'];

/*$db_host = 'localhost:8889';
$db_username = 'root';
$db_password = 'root';
$db_name = 'Event';*/

mysql_connect( $db_host, $db_username, $db_password) or die(mysql_error());
mysql_select_db($db_name); 

// search submission ID

$query = "SELECT * FROM 'demo' WHERE 'Name' = '$ID'";
$sqlsearch = mysql_query($query);
$resultcount = mysql_numrows($sqlsearch);

if ($resultcount > 0) {

    mysql_query("UPDATE `demo` SET 
                                `Name` = '$Name',
                                `Comment` = '$Comment',     
                             WHERE `ID` = '$ID'") 
     or die(mysql_error());

} else {

    mysql_query("INSERT INTO `demo` (ID, Name, Comment) VALUES ('$ID','$Name', '$Comment') ") 
    or die(mysql_error());  

}

header('Location: index.php');
?>'

viewing.php：

        <style rel="stylesheet" type="text/css">
            body {
                font-size:20pt;
            }   
        </style>        

<body>
<?php
require 'config.php';

$conn = mysqli_connect( $db_host, $db_username, $db_password, $db_name);

// Create connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT Name, Comment FROM demo";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    //echo "<table><tr><th>Name</th><th>Comment</th></tr>";
    // output data of each row
    while($row = $result->fetch_assoc()) {
        //echo "<tr><td>".$row["Name"]." ".$row["Comment"]."</td></tr>";
        echo "<fieldset>From : ".$row["Name"]."<br>".$row["Comment"]."<br></fieldset><br>";
    }

} else {
    echo "0 results";
}
$conn->close();
?>
</body>

的config.php：

<?php
/*Configuration Settings*/
$db_username = 'root';
$db_password = 'root';
$db_name = 'Event';
$db_host  = 'localhost';
$port = 8889;
$socket = 'localhost:/Applications/MAMP/tmp/mysql/mysql.sock';

?>

提交后刷新表单
