text element cookie help

[paulmo]

how to recall name submitted in form for returning user? and possibly echo as well on same page in greeting? lots of code googling (pop up boxes, cgi page links), but no success yet with what would seem to be a basic procedure. thanks for direction—

 

<form name="myform" action="process.php" method="POST">
    <input type="hidden" name="check_submit" value="1"/>

</p><p>First Name: 
<input type="text" name="name" class="buttonsb"/>

trying with jquery...is this getting closer? thanks

 

<script type="text/javascript" src="jquery-1.2.6.min.js"></script>     

$.cookies.get('name', 'text'); 
$.cookies.set('name');          

<form method="post" action="contact.php"> 

<input type="hidden" name="redirect" value="xxx.php" /></p><p>
Name: <br/>
<input name="name" type="text" size="20" class="buttonsb"></p>
<p><input type="submit" name="submit" value="Send" class="buttons"/> </p>
</form>

You would do something like this.

 

if (isset($_COOKIE["user"])) {
$user_name = $_COOKIE["user"];
} else {
    $user_name = "Guest";
}
?>

</pre>
<form name="myform" action="process.php" method="POST">
    


First Name: 
<

 

You also have to set the cookie somewhere, (maybe after the user logs in), by doing:

 

setcookie("user", "name_here", time()+3600);

 

Try it and come back with specific questions.

thanks maq this is what i've got. not sure where to set cookie. there's no log in, only a form that gets processed by process.php. want to recall first name only so when user returns, name will be in form field (or use to create greeting).

<?php
if (isset($_COOKIE["user"])) {
$user_name = $_COOKIE["user"];
} else {
    $user_name = "Guest";
}
?>

<form name="myform" action="process.php" method="POST">
    <input type="hidden" name="check_submit" value="1"/>

</p><p>First Name: 
<?php echo $user_name; ?>
<input type="text" name="name" class="buttonsb"/></p><p>
<input type="submit" value="Process" class="buttons" onclick="return CapitalizeNames()">
</form>

setcookie("user", "name_here", time()+3600);

there's no log in, only a form that gets processed by process.php.

 

Then you should set it in process.php.  It should look something like this:

 

setcookie("user", $_POST['name'], time()+3600);

 

So when you submit to process.php you get the text field for the name they typed in. 

 

Keep in mind time()+3600 is in seconds.  So 3600 = 1 hour.  You should modify if you want the cookie to last longer.

anywhere put setcookie on process.php page getting this:

Warning: Cannot modify header information - headers already sent 

[Maq]

Code?

[paulmo]

this process.php processes the form and inserts values in database table. i've put the setcookie near the bottom. again, error message was appearing no matter setcookie location. thanks!

 

<?php
ini_set("display_errors", 1);
error_reporting(E_ALL); 

mysql_connect("xxx", "xxx", "xxx") or die(mysql_error()); 
mysql_select_db("xxxx") or die(mysql_error()); 
$name = mysql_real_escape_string($_POST['name']);
$theme = mysql_real_escape_string($_POST['theme']);
mysql_query("INSERT INTO xxx (name, theme, created) VALUES ('$name', '$theme', NOW()) ") or die(mysql_error());
$row_id = mysql_insert_id(); //Put it in a variable for later 

?>

<script type="text/javascript" src="jquery-1.2.6.min.js"></script>
<script type="text/javascript">
  $(function(){ //This syntax will execute when the page is done loading
    $.post("geo.php",
    {geoip_city: geoip_city(),
      geoip_region_name: geoip_region_name(),
      row_id: '<?php echo $row_id; ?>' //Pass it with the JavaScript
   // },function(message){ alert(message);
    });
  });
</script>

<?php

switch (intval(date('n')))
{
case 1: case 2: case 3:

#there's about 10 pages of code in here with $phrase variables that echo statements dependent on radio form field]
}

setcookie("user", $_POST['name'], time()+3600);

?>

Put it towards the top.

 

I assume you're going to have some validation for user names.  Right after you validate you should set the cookie.  For now just put it here:

 

ini_set("display_errors", 1);
error_reporting(E_ALL); 

mysql_connect("xxx", "xxx", "xxx") or die(mysql_error()); 
mysql_select_db("xxxx") or die(mysql_error()); 
$name = mysql_real_escape_string($_POST['name']);
$theme = mysql_real_escape_string($_POST['theme']);
mysql_query("INSERT INTO xxx (name, theme, created) VALUES ('$name', '$theme', NOW()) ") or die(mysql_error());
$row_id = mysql_insert_id(); //Put it in a variable for later 
setcookie("user", $_POST['name'], time()+3600);
?>
