Question

我正在尝试使用HTML MySQL和PHP将数据从数据库中获取到HTML页面。

我创建了一个包含代码和html的php文件，按下按钮我调用该函数并在表格中显示信息（下面的代码）。

PHP：

<?php
include 'connection.php';

$sql = "SELECT cName, cEmail, cPhone, cOtherPhone, cAddress, cNeighborhood FROM Client WHERE cEmail='ka@dkdk.com'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
    echo "Name: " . $row["cName"]. "<br>";
    echo "Email: " . $row["cEmail"]. "<br>";
    echo "Phone number: " . $row["cPhone"]. "<br>";
    echo "Other Phone number: " . $row["cOtherPhone"]. "<br>";
    echo "Address: " . $row["cAddress"]. "<br>";
    echo "Neighborhood: " . $row["cNeighborhood"]. "<br>";
}
} else {
echo "0 results";
}
?>

HTML

<HTML>
<HEAD>
  <TITLE>
     A Small Hello 
  </TITLE>
</HEAD>
<BODY>
<div>
    <form id="myform" action="/My-code/getMyAccount.php" method="post">

    <div class="button">
        <button type="submit" name="submit">Update</button>
    </div>
</form>
</BODY>
</HTML>

到目前为止一切正常。现在我想显示内容而不按任何按钮。我正在做的是在html中添加php代码：

<HTML>
<HEAD>
  <TITLE>
     A Small Hello 
  </TITLE>
</HEAD>
<BODY>
<?php
include 'connection.php';

$sql = "SELECT cName, cEmail, cPhone, cOtherPhone, cAddress, cNeighborhood FROM     Client WHERE cEmail='ka@dkdk.com'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
    echo "Name: " . $row["cName"]. "<br>";
    echo "Email: " . $row["cEmail"]. "<br>";
    echo "Phone number: " . $row["cPhone"]. "<br>";
    echo "Other Phone number: " . $row["cOtherPhone"]. "<br>";
    echo "Address: " . $row["cAddress"]. "<br>";
    echo "Neighborhood: " . $row["cNeighborhood"]. "<br>";
    }
} else {
    echo "0 results";
}
?>
</BODY>
</HTML>

我没有收到任何错误，也在控制台写入200 ok。但是没有数据显示。我该如何解决这个问题？

Html页面不支持php标签所以你必须创建一个php文件，然后尝试下面的代码：

<?php
include 'connection.php';

$sql = "SELECT cName, cEmail, cPhone, cOtherPhone, cAddress, cNeighborhood FROM     Client WHERE cEmail='ka@dkdk.com'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
    echo "Name: " . $row["cName"]. "<br>";
    echo "Email: " . $row["cEmail"]. "<br>";
    echo "Phone number: " . $row["cPhone"]. "<br>";
    echo "Other Phone number: " . $row["cOtherPhone"]. "<br>";
    echo "Address: " . $row["cAddress"]. "<br>";
    echo "Neighborhood: " . $row["cNeighborhood"]. "<br>";
    }
} else {
    echo "0 results";
}
?>

在内部制作表格以格式化您的输出。

将文件扩展名更改为 .php

    <table>
        <tr>
        <td>Name</td>
        <td>email</td>
        <td>ph_no</td>
        <td>Address</td>
        </tr>
        <?php
        $sql="SELECT * FROM tab_name";
        $result=mysql_query($sql);
        while($row = $result->fetch_assoc()) {
        {
            ?>
            <tr>
            <td><?php echo $row['col1'] ?></td>
            <td><?php echo $row['col2'] ?></td>
            <td><?php echo $row['col3'] ?></td>
            </tr>
            <?php
        }
        ?>
</table>
