如何在html表中使用sql查询结果

Question

我正在尝试创建一个 html 表，显示来自 php sql 查询的结果。 这是学生php代码的结果页面如下

$r1=$_GET["r"];
$con=mysqli_connect(localhost,chumspai_tlss,Tls121,chumspai_tlsResult);

if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM nursery_blue_ WHERE sr_='$r1'");

while($row = mysqli_fetch_array($result))
{

html代码是

<pre>
<form name="frmResult" id="frmResult" action="" method="post" onsubmit="return checkEmpty();">
  <table width="80%" cellpadding="5" cellspacing="5" border="0">
    <tr>
      <td class="heading noborder">Enter Your Roll Number:</td>
      <td class="noborder"><input type="text" id="r" name="r" value="" /></td>

请帮助我如何将这个 php 查询嵌入到这个 html 表和 html 表单中。

Answer 1

你不是那么远。

变量 $row 是一个包含数据的数组。 试试这个，看看它在你的 while 调用中的结构：

print_r($row);

使用此命令，您将看到数组中每个项目的名称。 在某处记下它。 然后你可以做这样的事情：

...<td><?php echo $row['desired_column_name']; ?></td>...

如果您从 mysql 查询接收数据，这应该可以解决问题。

希望它有所帮助，保罗

尝试这个 ：

       $result = mysql_query("select * from emp");
       while($row = mysql_fetch_array($result))
  {
      echo "<tr>";               
            echo "<td id=SrNo$cnt >".$row['eno']."</td>";               
            echo "<td id=ItemId$cnt >".$row['eId']."</td>";               
            echo "<td>". "<button name='Update' id='update' onclick='show(".$cnt.")'>UPDATE</button>"."</td>";
            echo "<td>". "<button name='Report' id='show' onclick='Report(".$row['SrNo'].")'>REPORT</button>"."</td>";
            echo "</tr>";
            echo "<div id=show$cnt>";
            echo "</div>";
            $cnt++;
 }
