Question

我的 PHP 文件中有2 isset()。添加新值是可以的，但在更新值似乎有效但不在数据库中。

这是我的PHP代码。

<?php


if(isset($_POST['btnposins'])) { 
     mysql_connect("localhost", "root", "") or die(mysql_error());
   //select database
 mysql_select_db("brm_dbs") or die(mysql_error());
$posi = mysql_real_escape_string($_POST['inputposi']);
//insert data using insert into statement
 $query = "Insert into admin_position(Position)Values('$posi')";
  if (mysql_query($query)) {
 //dislay a message box that the saving is successfully save
 echo "<script type=\"text/javascript\">
        alert(\"New Position has been posted.\");
        window.location = \"new_admin.php\"
        </script>";

} else {
  echo("Failed: " . mysql_error());
} 

} 
else if(isset($_POST['btnposave'])) {
     mysql_connect("localhost", "root", "") or die(mysql_error());
   //select database
 mysql_select_db("brm_dbs") or die(mysql_error());
$posid = $_POST['posid'];
$posname = $_POST['posname'];
//insert data using insert into statement
 $query = "UPDATE admin_positon SET Position='$posname' WHERE uid='$posid'";
                        //execute the query
                        mysql_query($query);
                            //header("Location: new_admin.php");
                            if (mysql_affected_rows() != 0) {
                            echo "<script type=\"text/javascript\">
                            alert(\"Position Name Edited\");
                            window.location = \"new_admin.php\"
                            </script>";
                        } else {
                            echo "<script type=\"text/javascript\">
                            alert(\"Position Name Not Edited\");
                            window.location = \"new_admin.php\"
                            </script>";
                        }

} else {

    echo 'No Tag'.mysql_error();
}


?>

我的代码中出现了什么问题？它始终返回＆＃39;位置名称已编辑＆＃39; ，即使我的值为空。

这是我的表格

已更新 似乎$_POST['posid'] AND $_POST['posname']没有传递值。什么造成这种情况？请帮助。

Answer 1

改变这个：

if (mysql_affected_rows() != 0) // OR change to !== 0

到此：

if (mysql_affected_rows() == 1) {

PHP数据库未更新
