Question

我有一个列表代理。一旦我选择并保存它，我想显示所选数据。我怎么能这样做？。我想在选定的列表中显示它，一旦我重新加载或返回到该页面

<?php
include_once("../noaccess.php"); 
include_once(CLASS_PATH."fetch_service.php"); 
$objfetch = new fetchService();
include_once(CLASS_PATH."proxy.php");
$objproxy = new Proxy();
include_once(CLASS_PATH."log.php"); 
$objlog= new changelog();
$account_id=$_SESSION['account_id'];
global $mysqli;
if($_POST['submit']=="Save")
{
    $pname=$_POST['proxy'];
    $query="UPDATE `proxy` SET `proxy_default`='1' where `proxyname`='$pname'";
    $mysqli->query($query) or die($mysqli->error);
    $_SESSION['check_update'] = "1";
    setcookie("msg","Proxy Seleted",time()+5,"/");
    header("location:".SITE_URL."index.php?view=default_proxy");
}
?>

Answer 1

您需要将$resrproxy['proxyname']值与$pname进行比较。你的代码应该是这样的：

// your code

<select name="proxy" id="proxy" class="required input">
    <option value="">Select</option>

    <?php
        $result = $objfetch->fetch_proxy("*","where account_id='".$_SESSION['account_id']."' ");
        foreach($result as $key=>$resrproxy){
            $option = "<option value=\"{$resrproxy['proxyname']}\"";
            if(isset($pname)){
                if($pname == $resrproxy['proxyname']){
                    $option .= " selected=\"selected\"";
                }
            }
            $option .= ">{$resrproxy['proxyname']}</option>";
            echo $option;
        } 
    ?>
</select> 

// your code   `

  <td>
  <select name="proxy" id="proxy" class="required input">
  <option value="">Select</option>

  <?php
  $result = $objfetch->fetch_proxy("*","where account_id='".$_SESSION['account_id']."' and `proxy_default`='1'");
  $pname=$result[0]['proxyname'];

  $result = $objfetch->fetch_proxy("*","where account_id='".$_SESSION['account_id']."' ");
  foreach($result as $key=>$resrproxy)
  {
  ?>
  <option value="<?php echo $resrproxy['proxyname'];?>"<?php echo $resrproxy['proxyname']==$pname ? "selected":"";?>><?php echo $resrproxy['proxyname'];?></option>
  <?php } ?>
</select>
  </td>
