Hi guys,
I have this code to verify the login of a certain user. What I want is when the login succedd it will load another page.
How can I do that?PHP Code:<?php
if(verify($name,$pass)!=1) echo "User Name or password is incorrect!";
else{
echo "Welcome: $name";
//Call here the page. mypage.php
}
?>
use this
PHP Code:header("Location: mypage.php\n \r");
thanks for the quick reply but I got this error: Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\Apache Group\Apache2\htdocs\connectmssql.php:31) in C:\Program Files\Apache Group\Apache2\htdocs\verifylog.php on line 32]
You can't use header() to redirect once you've sent data output (echo "Welcome: $name") - you can either use a meta tag to redirect after a timeout, or you can redirect straight away without sending any output (the quicker way).
pen I tried to remove the echo thingy in the else statement but nothing happens it still throws an error.
PHP Code:if(verify($name,$pass)!=1) echo "User Name or password is incorrect!";
else{header("Location: mypage.php");}
?>
//and here's the verify function
function verify($name,$pass){
$query="select 1 from table where name='$name' and password='$pass'";
$r=mssql_query($query);
$max=mssql_num_rows($r);
return $max;
}
See the bit in the error where it says
The file and line it points to, look there - that is the bit you need to change. Anything like echo, print, or anything outsite <?php ?> tags needs to go.Quote:

Pen here's the code about connectmssql.php. It'a class for the connection through my database. What thing should I remove here? Sorry to ask such a noob question but this is my first time playing w/ php, actually this is my first project in php. So please bear w/ me.
PHP Code:<?php
class DBConnect{
private $host;
private $user;
private $pw;
private $link;
public function myconnect($host,$user,$pw)
{
$this->host=$host;
$this->user=$user;
$this->pw=$pw;
$this->link=mssql_connect($this->host,$this->user,$this->pw);
if(!$this->link)
{
die('could not connect'.mssql_error());
}
}
public function myclose()
{
mssql_close($this->link);
}
}
?>
Seems fine. Make sure there are no trailing characters after the closing ?> tag. < must be the first character and > the last, as anything outside them will be outputted.
Pen here's my full code. Any wrong w/ it?
PHP Code:<?php
require 'connectmssql.php';
$db=new DBConnect;
$name=$_POST['name'];
$pass=$_POST['pass'];
$db->myconnect('xx','xx','xxxx');
mssql_select_db('xx');
function verify($name,$pass){
$query="select 1 from dtrlog where name='$name' and password='$pass'";
$r=mssql_query($query);
$max=mssql_num_rows($r);
return $max;
}
$db->myclose();
?>
<html>
<head><title>DTR</title>
<link rel='stylesheet' type='text/css' href='mystyle.css'>
</head>
<body>
<table>
<tr><td><img src='images/xxx.jpg'></td></tr>
</table>
<table cellpadding='3' cellspacing='3'>
<tr><td class='small'>
<?php
if(verify($name,$pass)==1){ header("Location: dtrshow.php");}
else{echo"<p class='bold'>User Name or password is incorrect!</p>";}
?></td></tr>
</table>
<hr>
</body>
</html>
you see me... i don't like the problems i encounter when i try using the
so my own way of always doing the redirection isPHP Code:header("Location: page.html");
and since i always use this JS function, i make it in to a php function so i can use it anytime(even when it subject to changes)Code:<script>
window.location = 'somepage.php';
</script>
this is how i do it.
so anytime i want to use it i do thisPHP Code:function jsredir($url){
<script>
window.location = '$url';
</script>
}
and viola...PHP Code:jsredir("mypage.html");
i like it when i do things like this(so simple)...
Sorry, missed that postQuote:
