[PHP] Nested database loops and completing an unordered list....
Good morning PHP groupies! I am working on this tool that will ultimately display a collapsible org chart. The org chart is based on a nested unordered list and that is the heart of my question. The NUL(nested unordered list) is based on a set of database queries - sometimes as many as 14 queries. Each query relies on data returned by all of the the queries before it. So what I am doing right now is this - query generates a list item while this list item get the next level dependent upon this item query generates this list item while this list item get the next level dependent on each list item above ...and so on.

Re: [PHP] Nested database loops and completing an unordered list....
I don't how how you keep your data in your database but there is no need to issues that many queries to retrieve your data. From what I understand the data you want to display is hierarchical.

Your situation sounds like list of categories for a e-commerce site.
Each category (like a person) is unique and may have a parent category
(boss) like that of a CEO.
** table structure:
CREATE TABLE IF NOT EXIST employees (
employeeID INT NOT NULL PRIMARY KEY,
bossID INT NOT NULL DEFAULT '0',
firstName VARCHAR(50) NOT NULL,
middle VARCHAR(50) NOT NULL,
lastName VARCHAR(50) NOT NULL
)
** SQL query:
SELECT * FROM employees ORDER BY bossID;
** PHP pseudo code:
// $employees = array(0 = array());
// CEO doesn't have a boss thus you get his/her info via $bigBossID =
$employees[0]['subordinates'][0];
// connect to DB
// execute query
// iterate results
while ($row = $result-fetch_assoc()) {
$employees[$row['employeeID']] = $row;
if (!empty($row['bossID'])
$employees[$row['bossID']]['subordinates'] = $row['employeeID'];
}
// free result
// close connection if need be
You can get any person's info via $employees[$employeeID] and get the
manager/director/VP/etc subordinates:
if (isset($employees[$employeeID]['subordinates'])
!empty($employees[$employeeID]['subordinates']))
foreach ($employees[$employeeID]['subordinates'] = $subordinateID) {
// access subordinate's info via $employees[$subordinateID]
}
else
echo {$employees[$employeeID]['firstName']} does not have subordinates.;
If there's any organizational change, the code still works.
HTH,
Tommy

Re: [PHP] Nested database loops and completing an unordered list....
[snip]…stuff…[/snip]
I am getting close, but I am also getting frustrated. I probably need to walk
away for a bit.
I have an array of tiers….
Array
(
[0] = TIER1DATA
[1] = TIER2DATA
[2] = TIER3DATA
[3] = BUSTIER1DATA
[4] = BUSTIER2DATA
[5] = BUSTIER3DATA
[6] = BUSTIER4DATA
)
Each of the tiers which represent parents in children in pairs. TIER1DATA is
the parent of TIER2DATA, etc. representing 7 columns of data. Here is my code
so far - any insight would be valuable and extremely appreciated by me.
function display_children($i, $child) {
global $dbc;
global $tierArray;
echo $i.br /;
/* retrieve children of parent */
$get = SELECT DISTINCT `. $tierArray[$i] .` FROM `POSITION_SETUP` ;
$get .= WHERE `COMPANY_ID` = '3' ;
if($i 0) {
$get .= AND ` . $tierArray[$i - 1] . ` = ' . $child . ' ;
}
echo $get.br /;
if(!($result = mysql_query($get, $dbc))) {
echo mysql_errno() . \t . mysql_error() . \n;
exit();
}
while($row = mysql_fetch_array($result)) {
/* indent and display the title of this child */
echo str_repeat('nbsp;',$i).$row[$tierArray[$i]].br /\n;
/* get the children's children */
display_children($i + 1, $row[$tierArray[$i]]);
}
}
It does produce the right query for only the first child in each case, I cannot
get it to go deeper. I have just been looking at it for too long. TVMIA!

Forgot to say that if I isolate any one level without recursion I get all of

It does produce the right query for only the first child in each case, I cannot
get it to go deeper. I have just been looking at it for too long. TVMIA!
Forgot to say that if I isolate any one level without recursion I get all of
the results for that level.
How are you calling this? What are your initial arguments?
What does your DB schema look like?
Can you show a brief example of the data in the table?
Dump: SELECT * FROM position_setup WHERE company_id='3'
Can you show the output of the function above?

I have an array of tiers….
Array
(
[0] = TIER1DATA
[1] = TIER2DATA
[2] = TIER3DATA
[3] = BUSTIER1DATA
[4] = BUSTIER2DATA
[5] = BUSTIER3DATA
[6] = BUSTIER4DATA
)
Each of the tiers which represent parents in children in pairs. TIER1DATA
is the parent of TIER2DATA, etc. representing 7 columns of data. Here is my
code so far - any insight would be valuable and extremely appreciated by me.
function display_children($i, $child) {
global $dbc;
global $tierArray;
echo $i.br /;
/* retrieve children of parent */
$get = SELECT DISTINCT `. $tierArray[$i] .` FROM `POSITION_SETUP` ;
$get .= WHERE `COMPANY_ID` = '3' ;
if($i 0) {
$get .= AND ` . $tierArray[$i - 1] . ` = ' . $child . ' ;
}
echo $get.br /;
if(!($result = mysql_query($get, $dbc))) {
echo mysql_errno() . \t . mysql_error() . \n;
exit();
}
while($row = mysql_fetch_array($result)) {
/* indent and display the title of this child */
echo str_repeat('nbsp;',$i).$row[$tierArray[$i]].br /\n;
/* get the children's children */
display_children($i + 1, $row[$tierArray[$i]]);
}
}
It does produce the right query for only the first child in each case, I
cannot get it to go deeper. I have just been looking at it for too long.

I initialize it by calling the function like this:
display_children(0, 0)
Each of the tiers is located in adjacent columns in a single table
tier1data, tier2data, tier 3 data……bustier1data, bustier2data…..
The array retrieves only the relevant tiers for this company and that is the
output of that array at the top of my example.

That way, a single query will get you all items in that parent's lineage to whatever depth is needed by using the child's value Select * from table where parent = '1/10' Would retrieve all items that are children of a top level of 1 and a second level of 10 Hth Bastien -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
