Question

我正在为学生信息创建教育结果页面。我基本上有2个查询，一个搜索从sql搜索滚动否，第二个是从名称搜索。当我将它组合在一个页面上时，我已经单独创建了它，它显示了两个结果，但我只需要一个结果，我的编码就是

<?php
include 'form.html';
$r1=$_GET["r"];
$n1=$_GET["n"];
$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))


 {
        echo'<table width="100%" cellpadding="10" cellspacing="0" border="0">';
        echo'<tr>'; 
        echo'<td class="heading grey" width="30%">'.RNO.'</td>';

请帮忙！

Answer 1

如果要在页面上显示一个结果集，则一次传递一个查询字符串parm。像这样http://yoursite.com/result.php?n=john或http://yoursite.com/result.php?r=5566 并将您的代码更改为此。

（代码未经过测试）

<?php
include 'form.html';
$con=mysqli_connect(localhost,username,password,database);

if (mysqli_connect_errno())
  {
  exit("Failed to connect to MySQL: " . mysqli_connect_error());
  }

if(isset($_GET['r'])) {
    // You must filter the User input .. to stop SQL injection attack's
 $r1 =  mysql_real_escape_string($_GET['r']);
$query = "SELECT * FROM nursery_blue_ WHERE sr_='$r1'";
$result = mysqli_query($con , $query);
// Proccess Loop
while($row = mysqli_fetch_array($result))

 {
        echo'<table width="100%" cellpadding="10" cellspacing="0" border="0">';
        echo'<tr>';
