[Resolved] Sending Data to a Function

JJ123

I am trying to send data to a function that I am calling but it doesn't seem to be working. I send three variables to a function and it is able to recognize one of the variables. I can print the variables right before calling the function but when I try to print the variables in the function, they print blanks.

Here is my calls to the functions:
updaterecord($number, $adminfirst, $adminlast);
displayrecord($number, $adminfirst, $adminlast);

Here is some partial code from one of the functions:
function displayrecord($number, $adminfirst, $adminlast)
{
//This code queries the record in the database that the user wants to view.
$query = "SELECT * FROM tblIssues WHERE IssueNumber LIKE '$number'";
$result = mssql_query( $query ) or die ("Query failed");
$line = mssql_fetch_array($result);
?><br>
Admin first in display:<input type="text" value="<?PHP $adminfirst ?>">

<form method="post" action="<?php echo $PHP_SELF?>">
<B><h3>Ticket Number:&nbsp<input type="Text" name="ticketnumber" value="<?php echo $line[IssueNumber] ?>" onFocus=this.blur()></B></h3>
.......

The part above:
Admin first in display:<input type="text" value="<?PHP $adminfirst ?>">
Does not contain the $adminfirst value.
Can someone please tell me what I am doing wrong?

Admin first in display:<input type="text" value="<?PHP $adminfirst ?>">

should be

Admin first in display:<input type="text" value="<?PHP echo $adminfirst ;?>">

I had echo in there but made a mistake when I was typing. Well I got the echo in there and the $adminfirst is appearing in that field. But I want the $adminfirst to keep it's value throughout the pages.

I have the form posting to itself. I think this causes the $adminfirst variable to be overwritten when the submit button is pressed.

What I am trying to do is keep the first and last name of the person who logged in. I am taking their username and determining what their first and last name is from the accounts table and putting those values into variables ($adminfirst and $adminlast). I need to keep the information so that I can use it in logs when they make changes.

How can I do this?

use sessions to store the values, its easier

I have taken a look at these in the past breifly but I am not sure how to send variables this way. I thought it was only meant for sending browser information. I am still fairly new at this.

Can you give me an example on how to use this with the code that I have supplied so far?

I am using Ms SQL 2000 and IIS if that makes a difference.

well in brief , the idea is this

check session variables to see if a person is logged in.
if the session variables are blank or dont exist then the person is not logged in
once a person logs in assign his firstname and lastname as session variables
when he logs out, destroy the session.

take a look at the manual

Do I need to have register_globals set to on in php.ini?

I am attempting to try this Session stuff. I have only entered SESSION_START();and I am already getting the following errors:

Warning: session_start() [function.session-start]: open(/tmp\sess_bbaa9887b0ea7ef205b580fa1b41bce2, O_RDWR) failed: No such file or directory (2) in c:\inetpub\wwwroot\niffer\ticketAdmin.php on line 7

In php.ini change session.save_path to somthing like

session.save_path = c:/temp

Make sure the directory temp is valid.

Great - that took care of one of the errors - making progress!

So what do I need to do to get rid of the following errors:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at c:\inetpub\wwwroot\niffer\ticketAdmin.php:2) in c:\inetpub\wwwroot\niffer\ticketAdmin.php on line 3

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at c:\inetpub\wwwroot\niffer\ticketAdmin.php:2) in c:\inetpub\wwwroot\niffer\ticketAdmin.php on line 3

You must not have any output before the session_start.
this include spaces before and spaces after the <?PHP

Try searching the forum for headers already sent... you'll find lots of ideas why and what can be done to fix the problems
