Re: [PHP] Creating arrays using results from MySQL query
You have to call mysql_fetch_array for each record in your result set...
$emp_login_wkgrp_id = array ();
$emp_login_grp_id = array ();
$emp_login_role_id = array ();
$i = 0;
while($employee_2 = mysql_fetch_array($result_2)){
$emp_login_wkgrp_id[$i] = $employee_2[wkgrp_id];
$emp_login_grp_id[$i] = $employee_2[grp_id];
$emp_login_role_id[$i] = $employee_2[role_id];
$i++;
}
mysql_fetch_array will return false when you run out of results, breaking
the while loop.
Check the manual for more info:

RE: [PHP] Creating arrays using results from MySQL query
Mark,
I'm still experiencing the same problem. Only one record is being added to
the arrays. There are currently two records in the DB workgroups table
matching the WHERE emp_id='$emp_login_id criteria.
Here's the 2 records in the DB workgroups table:
FIELDS Value#1 Value#2
wkgrp_id1 4
grp_id 111 222
emp_id 39 39
wkgrp_create_date 2002-03-16 23:45:43 -00-00 00:00:00
wkgrp_change_date 2002-03-16 23:45:43 -00-00 00:00:00
wkgrp_change_by webmaster webmaster
wkgrp_create_by webmaster webmaster
role_id 1 1
I'm only getting back Value#2.
Here's the modified PHP code:
File: login.php
if ($employee_2){
$emp_login_wkgrp_id = array();
$emp_login_grp_id = array();
$emp_login_role_id = array();
$i = 0;
while($employee_2 = mysql_fetch_array($result_2)){
$emp_login_wkgrp_id[$i] = $employee_2[wkgrp_id];
$emp_login_grp_id[$i] = $employee_2[grp_id];
$emp_login_role_id[$i] = $employee_2[role_id];
$i++;
}
session_register('emp_login_wkgrp_id');
session_register('emp_login_grp_id');
session_register('emp_login_role_id');

RE: [PHP] Creating arrays using results from MySQL query
Hi Guys,
I've finally been able to figure this out. Turns out, I had to make
another, different SQL query to the DB instead of re-using the prior SQL
query statement.
The *new* code looks like this:
File: login.php
# if $employee_1, query db workgroups table to check if $emp_login_id
belongs to any groups
$sql_2 = SELECT * FROM workgroups WHERE emp_id='$emp_login_id';
$result_2 = @mysql_query($sql_2) or die (mysql_error());
$employee_2 = mysql_fetch_array($result_2);
# if match, set workgroups login variables in array, then register
workgroups login variables in session
if ($employee_2){
$emp_login_wkgrp_id = array();
$emp_login_grp_id = array();
$emp_login_role_id = array();
$i=0;
$result_3 = @mysql_query($sql_2) or die (mysql_error());
while($employee_3 = mysql_fetch_array($result_3)){
$emp_login_wkgrp_id[$i] = $employee_3[wkgrp_id];
$emp_login_grp_id[$i] = $employee_3[grp_id];
$emp_login_role_id[$i] = $employee_3[role_id];
$i++;
}
session_register('emp_login_wkgrp_id');
session_register('emp_login_grp_id');
session_register('emp_login_role_id');
}
Now when I print_r(array_values($emp_login_grp_id)); I get the following
values: Array ( [0] = 111 [1] = 222 [2] = 333 ).
Many thanks to everyone (Mark) for all of your help.

Subject: FW: [PHP] Creating arrays using results from MySQL query
I've just added another record to the table. Now they're a total of 3
records matching the WHERE emp_id='$emp_login_id criteria. When I
print_r(array_values($emp_login_grp_id)); I get the following values:
Array ( [0] = 222 [1] = 333 ). For some reason, it seems to be skipping
the first record.

RE: [PHP] Creating arrays using results from MySQL query
I should have been more exact in my original reply. The second query
isn't necessary. Try this:
File: login.php
# if $employee_1, query db workgroups table to check if $emp_login_id
belongs to any groups
$sql_2 = SELECT * FROM workgroups WHERE emp_id='$emp_login_id';
$result_2 = mysql_query($sql_2) or die (mysql_error());
# initialize empty arrays
$emp_login_wkgrp_id = array();
$emp_login_grp_id = array();
$emp_login_role_id = array();
$i=0;
# while there are matches, set workgroups login variables in array, then
# register workgroups login variables in session
while($employee_2 = mysql_fetch_array($result_2)){
$emp_login_wkgrp_id[$i] = $employee_2[wkgrp_id];
$emp_login_grp_id[$i] = $employee_2[grp_id];
$emp_login_role_id[$i] = $employee_2[role_id];
$i++;
}
session_register('emp_login_wkgrp_id');
session_register('emp_login_grp_id');
session_register('emp_login_role_id');
