当我在 php 页面上使用表单更新 Mysql 表时,当我点击提交时页面不会自动刷新。我必须点击刷新才能看到更新的行。我试过了,但这也没有任何好主意?

你现在能看到吗?$editresim值为$info[resim]

当您提交表单时,$info[resim]当前数据库值。数据库在下面/之后更新。

提交时,您仍然会看到提交的值实际放入数据库之前的先前数据。因此,您需要重新打开该页面才能查看更新的数据。

修复它的一种方法是,您应该将更新数据的代码移到顶部,在您之前SELECT * FROM CloseOut WHERE itemNO=$edit,以便查询将为您提供最新/更新的数据。

很抱歉没有提供示例代码,但恐怕我会犯一些可能会增加混乱的小错误。如果您尝试自己解决它实际上会更好。

祝你好运!

ps:你的逻辑

Get data from db

Put to data to VAR

If form is submitted:

    Update data in DB

Show VAR // This is *not* the latest submitted data

问题是您在获得信息更新数据库。

把这部分代码

//Resimlerin yuklenecegin yer
 $target = "../../upload/";  
 //////////////////////////////////////////////////////////////////////
 ///////////////////////////////Resim1/////////////////////////////////
 //////////////////////////////////////////////////////////////////////
 $target1 = $target . basename( $_FILES['resim1']['name']) ; 
 //Formdan gelen bilgileri almasi icin
 $resim=($_FILES['resim1']['name']); 
 $isim=$_POST['isim1']; 
 $alan1=$_POST['alan11']; 
 $alan2=$_POST['alan21']; 
 $alan3=$_POST['alan31']; 
 $alan4=$_POST['alan41']; 



/////////////Formdaki bos alanlara bos bilgi kayit etmemesi icin////////////////////////

$updates = array();
if (!empty($resim))
  $updates[] = 'resim="'.mysql_real_escape_string($resim).'"';
if (!empty($isim))
  $updates[] = 'isim="'.mysql_real_escape_string($isim).'"';
if (!empty($alan1))
  $updates[] = 'alan1="'.mysql_real_escape_string($alan1).'"';
if (!empty($alan2))
  $updates[] = 'alan2="'.mysql_real_escape_string($alan2).'"';
if (!empty($alan3))
  $updates[] = 'alan3="'.mysql_real_escape_string($alan3).'"';
if (!empty($alan4))
  $updates[] = 'alan4="'.mysql_real_escape_string($alan4).'"';
$updates = implode(', ', $updates);


/////////////////////////////////////////////////////////////////////////////////////////
 //update etmesi icin
if(move_uploaded_file($_FILES['resim1']['tmp_name'], $target1)) 
{   
mysql_query("UPDATE CloseOut SET $updates WHERE itemNO='$edit' ");
echo "Tebrikler, ". basename( $_FILES['resim1']['name']). " isimli dosya yuklendi ve database'e basariyla islendi!<br>"; 
 } 

就在之前:

$edit = htmlspecialchars(stripslashes($_GET['edit']));
