Functions and variables.

MBK

Help!

I currently have a script that calls a form from a different script, and I now need to assign fields in my form values, based on variables I have in my script.

Confused? I am...
edit.php - holds variables that are to be placed in the form called from a function in signup.php.

My problem arises when I am trying to display the values in their fields, the form is coming up blank on the screen, I know I have all the variables set correctly, just don't know how to place them into the fields.

Apologies if this is confusing, maybe that is part of my problem but all help is appreciated.

jmcneese

how are you passing the variables? via POST or SESSION?

MBK

currently using sessions.

Here goes,
There are 2 scripts, the first one contains the code to display the form:

<?

function show_form(){

echo"<html>
<head>
<script>

function checkrequired(which){
var pass=true
if (document.images){
for (i=0;i<which.length;i++){
var tempobj=which.elements[i]
if (((tempobj.type=='text'||tempobj.type=='password')&&tempobj.value=='')||(tempobj.type.toString().charAt(0)=='s'&&tempobj.selectedIndex==-1)){
pass=false
break

}
}
}
if (!pass){
alert('You have not completed all the required information.\\r\\nPlease complete your entry and then re-submit.')
return false
}
else
return true
}
</script>

</Head>

The second page is the once that queries a db and should insert values:-

<?
session_start();

if (!session_is_registered("SESSION"))
{
header("Location: /error.php");
exit();
}



$user=$HTTP_SESSION_VARS['SESSION_UNAME']; //define the username from the session name.

$connection=mysql_connect('localhost','root');//connect to the database
mysql_select_db('reseller');//select the database to use

  $userdata=mysql_fetch_assoc(mysql_query("select * from user where user ='$user'")); //select the user details from db.

   $pass=$userdata['pass'];
   $email=$userdata['email'];
   $company=$userdata['company'];

  $contactdata=mysql_fetch_assoc(mysql_query("select * from contact where email ='$email'"));
   $first=$contactdata['first'];
   $surname=$contactdata['surname'];
   $position=$contactdata['position'];
   $phone=$contactdata['phone'];

  $companydata=mysql_fetch_assoc(mysql_query("select * from company where company='$company'"));
   $address=$companydata['address'];
   $address2=$companydata['address2'];
   $county=$companydata['county'];
   $postcode=$companydata['postcode'];
   $tel=$companydata['tel'];
   $fax=$companydata['fax'];
   $web=$companydata['web'];

require("signup.php");
show_form($pass);

?>

Any help is appreciated, I can't make too many changes to the form, as it will also be used in the first instance as a signup form, and in this case it is being used again in case users need to change their inputted information.

Thanks.

a couple things:

why is the code for displaying the form in a function? try using the "print <<<EOF" method.

you need to start the session using the same session_id for the signup form. then you can specify default values based upon the values stored in the session.

example:

<input type="text" name="company" size="35" value="<? 
if (isset($_SESSION['company']) && !empty($_SESSION['company'])) {
    echo $_SESSION['company'];
} 
?>">

don't forget, when you submit a form, all the form elements (that is all the name="" bits are added to an array called $POST. you can take these elements and save them to the session, or you may use them as is (substitute $SESSION with $_POST in the above example.

is this what you mean?

MBK

it looks like it should work, I will try it out now, thanks for your help.

What is the print" >>> EOF" all about?

That hasn't worked,

I am now getting an error message T_ENCAPSED AND WHITESPACE expecting T_STRING or T_VARIABLE or T_NUM_STRING.

and then a fatal error beneath saying there is a call to an undefined function.

Any ideas?

MBK

This does kind of work, but not.....

The original form is available to complete by anyone, no sessions nothing, the edit.php is available after people have logged in and are in a session based on the user id.

I need to fill the edit.php with the values, as shown above.

So the $_SESSION['company'] won't work (I don't think) as I haven't set that anywhere.
All the user has logged in using is a username and password. When they load edit.php it should link to the form and load with the values that are shown in the edit.php above.

Hope this explains it better and u can help.

Thanks
