Question

我试图从数据库中获取数据并将其存储在下面创建的表中。事情是没有错误消息，没有，但表中没有数据，但它创建了所需的页面数量 - 5（每页20个记录 - 在db中总共100个记录）

这里是我们页面的代码：

<?php 
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "payment";

$connection = new mysqli($servername, $username, $password, $dbname);


if (isset($_GET["page"])) { $page  = $_GET["page"]; } else { $page=1; }; 
$start_from = ($page-1) * 20; 
$sql = "SELECT * FROM banks ORDER BY BankName ASC LIMIT $start_from, 20"; 
$rs_result = mysqli_query ($connection,$sql); 

?> 
<table>
<tr><td>BankName</td><td>BIC</td></tr>
<?php 

while ($row = mysqli_fetch_assoc($rs_result)) { 
?> 
            <tr>
            <td><? echo $row["BankName"]; ?></td>
            <td><? echo $row["BIC"]; ?></td>
            </tr>
<?php 
}; 
?> 
</table>
<?php 
$sql = "SELECT COUNT(BankName) FROM banks"; 
$rs_result = mysqli_query($connection,$sql); 
$row = mysqli_fetch_row($rs_result); 
$total_records = $row[0]; 
$total_pages = ceil($total_records / 20); 

for ($i=1; $i<=$total_pages; $i++) { 
            echo "<a href='pagination.php?page=".$i."'>".$i."</a> "; 
}; 
?>

数据库名称：付款

这是我如何填补表格＆＃39;银行＆＃39;在mysql中

DROP TABLE `banks`;

CREATE TABLE `banks` (

所以，我不明白为什么我在页面中创建了0个信息，它也给了我0个错误。

Answer 1

更正您的代码在表格中添加php标记。

            <tr>
            <td><?php echo $row["BankName"]; ?></td>
            <td><?php echo $row["BIC"]; ?></td>
            </tr>

Answer 2

尝试替换

while ($row = mysqli_fetch_assoc($rs_result))

与

while ($row = $rs_result->fetch_assoc()) {

和

<? echo

带

<?=

或

<?php echo

Answer 3

只需在脚本开头添加调试代码：

的error_reporting（-1）; ini_set（'display_errors'，1）;

查看显示的错误。

无法从mysql接收数据
