标题不工作PHP [英] headers not working PHP

问题描述

在提交之后，abc.html将跳转到这个PHP页面。
这是页面PHP1.php在这里我试图验证用户输入，如果名称和ID在数据中，他将被转发填写第二部分的注册，如果不是它只会给出错误。

 <？php 
 session_start（）; 
 $ _SESSION [acb] =好的; 
 $ _SESSION ['team'] = $ _POST ['team_name']; 
 $ con = mysql_connect（localhost，user，password）; 
 if（！$ con）
 {die（'Could not connect：'。mysql_error（））;} 
 mysql_select_db（mydbName）; 
 if（isset（$ _ POST ['team_name']，$ _ POST ['id']））{
 $ team_name = mysql_real_escape_string（$ _ POST ['team_name']）; 
 $ id = mysql_real_escape_string（$ _ POST ['id']）; 
 if（！empty（$ team_name））{
 $ result = mysql_query（SELECT COUNT（`teamname`）FROM`table` WHERE`teamname` ='$ team_name'AND`id` =' $ ID'）; 
 $ team_result = mysql_fetch_row（$ result）; 
 if（$ team_result [0] =='0'）{//如果不存在，则打印失败。 
 echo'Varification failed'; 
} else {
 header（'Location：http://www.abc.com/REGISTERpart2.php'）; 
}}}？> 
  

RegisterPART2.php是我检查会话是否存在的地方（我在最后一个文件）。如果不是，我想重新回到表格填写，然后填写第一个表格，然后进入注册部分2

 `<？php 
 session_start（）; 
 $ name = $ _SESSION ['team']; //存储在会话中的值，我在这个页面上使用
 if（（$ _SESSION [abc]！=='good'））{
 header（'Location：http：// www .abc.com / page1.html'）; //带回第1阶段，因为用户没有填写第一部分。 
} 
 else {
 echo $ name。 '您已完成注册程序第一部分，您可以继续！';

}

}

Page 1 abc.html.. on submit it will jump to this PHP page . This is page PHP1.php here i am trying to validate user input if name and id in in data he will be forwarded to fill out second part of registration if not it will just give error.

<?php
session_start();
$_SESSION["acb"] = "good";
$_SESSION['team'] = $_POST['team_name'];
$con = mysql_connect("localhost", "user", "password");
if (!$con)
  {die('Could not connect: ' . mysql_error());}
mysql_select_db("mydbName");
if(isset($_POST['team_name'],$_POST['id'])){
 $team_name =   mysql_real_escape_string($_POST['team_name']);
$id =   mysql_real_escape_string($_POST['id']);
if (!empty($team_name)) {
$result= mysql_query("SELECT COUNT(`teamname`) FROM `table` WHERE `teamname`='$team_name' AND `id`='$id'");    
        $team_result = mysql_fetch_row($result);
    if ($team_result[0] == '0') { //if does not exist print failed.
            echo 'Varification failed';
        } else {
 header('Location: http://www.abc.com/REGISTERpart2.php');
}} }  ?>

RegisterPART2.php is where i am checking my session exist or not (the one i started in last file). if not i want to redirect back to form one and fill that first then come to registration part 2

 `<?php
 session_start();
 $name = $_SESSION['team']; //a value stored in session which i used on this page  
if (($_SESSION["abc"] !== 'good')) {
header('Location: http://www.abc.com/page1.html');  //take back to stage 1 coz user did not fill first part.
}
else{
echo $name. 'you have completed register process part one you may continue!';
}

?>

解决方案

If you're using the new MySQL version (MySQLi), so the first page will become:

<?php
session_start();
$_SESSION["acb"] = "good";
$_SESSION['team'] = $_POST['team_name'];
$con = new mysqli("localhost", "user", "password", "mydbName");
if (!$con) {
    die('Could not connect: ' . $con->error());
};   
if (isset($_POST['team_name'],$_POST['id'])) {
$team_name = $con->real_escape_string($_POST['team_name']);
$id = $con->real_escape_string($_POST['id']);
if (!empty($team_name)) {
$result = $con->prepare("SELECT COUNT(`teamname`) FROM `table` WHERE `teamname`='$team_name' AND `id`='$id'"); 
$result->execute();
$result->bind_result($one,$two,$three,$etc);
$result->fetch();
if (empty($one) and empty($two) and empty($three) and empty(etc)) { // may be and/or (pick one)
    echo 'Varification failed';
} else {
    header('Location: http://www.abc.com/REGISTERpart2.php');
}
}
}  
?>
