[SOLVED] foreach/while loop = confusion

piznac · January 30, 2007

Ok I have two tables in a rather small database. One holds 3 fields one being a "store number". The other holds info about projects completed for these stores. What I need is to lisst the stores and the projects completed. I can do this,. but not the way I want. I want it to be like this:

Store#1 = project1,project2,project3,..etc.
Store#2 = project1,project2,project3,..etc.

The only thing I can get is:

Store#1 = project1
Store#1 = project2
Store#1 = project3,..etc.
Store#2 = project1,..etc.

I know there must be a way to do this, but am unsure how. This is what I have so far:

[code]<?php require_once('../../Connections/conner.php'); ?>
<?php
$dm = $_GET['dm'];
mysql_select_db($database_conner, $conner);
$query_dmstore = "SELECT * FROM dmrmst";
$dmstore = mysql_query($query_dmstore, $conner) or die(mysql_error());
$row_dmstore = mysql_fetch_assoc($dmstore);
$totalRows_dmstore = mysql_num_rows($dmstore);
?>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title></title>
</head>

<body>
<?php do { ?>
<?php $num = $row_dmstore['store']; ?>
<?php
$numbs = explode(" ", $num);
foreach($numbs as $value){
mysql_select_db($database_conner, $conner);
$query_store = "SELECT * FROM pog_check WHERE `storenum` = '$value'";
$store = mysql_query($query_store, $conner) or die(mysql_error());
$row_store = mysql_fetch_assoc($store);
$totalRows_store = mysql_num_rows($store);
$pog = $row_store['storenum'];
$pogs = explode(" ", $pog);
foreach ($pogs as $value2){
echo "$value2 = $row_store[pogtype] ";
}
}

?>
<?php } while ($row_dmstore = mysql_fetch_assoc($dmstore)); ?>

</body>
</html>
<?php
mysql_free_result($dmstore);

mysql_free_result($store);
?>[/code]

I know this is probably all wrong,. but I cant seem to wrap my head around this. Any help would be great,.. and if you need more info please tell me.

maybe this will shed some light on things:
[code]
<?php
$sql1 = "SELECT store_number FROM stores_table";
$query1 = mysql_query($sql1);

while($storenum = mysql_fetch_array($query1)){
$sql2 = "SELECT project FROM projects_table WHERE store_id = ". $storenum['store_number'] ."";
$query2 = mysql_query($sql2);

$projects_array = array();
while($row = msyql_fetch_array($query2)){
$projects_array[] = $row['project'];
}
$string = explode(", ", $projects_array);

echo "Store#". $storenum['store_number'] ." = ". $string ." \n";
}
?>
[/code]

Ok sorry now Im even more confused. Now Im getting a inf loop of the first store number. Here's what I have:

[code]<?php require_once('../../Connections/conner.php'); ?>
<?php
$dm = $_GET['dm'];
mysql_select_db($database_conner, $conner);
$query_dmstore = "SELECT * FROM dmrmst";
$dmstore = mysql_query($query_dmstore, $conner) or die(mysql_error());
$row_dmstore = mysql_fetch_assoc($dmstore);
$totalRows_dmstore = mysql_num_rows($dmstore);

while($totalRows_dmstore = mysql_num_rows($dmstore)){
mysql_select_db($database_conner, $conner);
$query_store = "SELECT * FROM pog_check WHERE `storenum` = ". $row_dmstore['store'] ."";
$store = mysql_query($query_store, $conner) or die(mysql_error());
$row_store = mysql_fetch_array($store);
$totalRows_store = mysql_num_rows($store);

while($row_store = mysql_fetch_array($store)){
$projects_array[] = $row['pog_type'];
}
$string = explode(", ", $projects_array);

echo "Store#". $row_dmstore['store'] ." = ". $string ."";
}
?>
[/code]

that's because you've got it wrong. i've taken a look at your code, and tried to see what it is you want to do... try this:
[code]
<?php
require_once('../../Connections/conner.php');

$dm = $_GET['dm'];
mysql_select_db($database_conner, $conner);

$query_dmstore = "SELECT * FROM dmrmst";
$dmstore = mysql_query($query_dmstore, $conner) or die(mysql_error());

$totalRows_dmstore = mysql_num_rows($dmstore);
echo "Total number of stores: ". $totalRows_dmstore ." \n";

while($row_dmstore = mysql_fetch_array($dmstore)){
$query_store = "SELECT * FROM pog_check WHERE storenum = ". $row_dmstore['store'] ."";
$store = mysql_query($query_store, $conner) or die(mysql_error());

while($row_store = mysql_fetch_array($store)){
$projects_array[] = $row['pog_type'];
}
$string = explode(", ", $projects_array);

echo "Store#". $row_dmstore['store'] ." = ". $string ." \n";
}
?>
[/code]

Still coming up with the same thing my friend. Here is the page:

[url=http://www.connerandassociates.com/pog_check/man/test_print2.php]http://www.connerandassociates.com/pog_check/man/test_print2.php[/url]

Im a bit confused about this

[code]$string = explode(", ", $projects_array);[/code]

Wouldnt that turn it into an array?

boo_lolly · January 30, 2007

hmmm... well you're not getting an infinite loop of the same store, anymore which is good.

yes you are right... it should be implode, not explode. just replace this:[code]$string = explode(", ", $projects_array);[/code]

with this:[code]$string = implode(", ", $projects_array);[/code]

and see what happens.

boo_lolly · January 30, 2007

can you display what your database tables look like? just the field names and the first few entries will be fine. i want to make sure we're calling the right columns in the right place... and what values we're looking for.

piznac · January 30, 2007

Sorry I seemed to be having a bit of trouble doing what you asked,.. give me a few mins.

piznac · January 30, 2007

ok the store tables is something like this

dmrmst:

rm---------------dm-------------[color=red]store[/color]
name------------name-----------store#

2nd one is like this:

auditready,followup,poponorder,displayorder,other,explain,date,pogtype,[color=red]storenum[/color],num,dm

boo_lolly · January 30, 2007

what's the name of your second table? is it pog_check?

and don't forget that you need to reset OR unset $projects_array:
[code]
<?php
require_once('../../Connections/conner.php');

$dm = $_GET['dm'];
mysql_select_db($database_conner, $conner);

$query_dmstore = "SELECT * FROM dmrmst";
$dmstore = mysql_query($query_dmstore, $conner) or die(mysql_error());

$totalRows_dmstore = mysql_num_rows($dmstore);
echo "Total number of stores: ". $totalRows_dmstore ." \n";

while($row_dmstore = mysql_fetch_array($dmstore)){
$query_store = "SELECT * FROM pog_check WHERE storenum = ". $row_dmstore['store'] ."";
$store = mysql_query($query_store, $conner) or die(mysql_error());

$projects_array = array(); //<--- you can reset it here
while($row_store = mysql_fetch_array($store)){
$projects_array[] = $row['pog_type'];
}
$string = explode(", ", $projects_array);

echo "Store#". $row_dmstore['store'] ." = ". $string ." \n";

unset($projects_array); //<---- OR you can reset it here.
}
?>
[/code]

pog_check

boo_lolly · January 30, 2007

show me a few lines that are above and below line 20. including line 20.
EDIT: i almost forgot! change this:[code]$projects_array[] = $row['pog_type'];[/code]

to this:[code]$projects_array[] = $row_store['pog_type'];[/code]

piznac · January 30, 2007

well I tried something there,. but changed it back. Also it is now working but not display the "pog_types" just the commas.

EDIT

Yeah I just changed that but still the same

this is what I have:

[code]<?php
require_once('../../Connections/conner.php');

$dm = $_GET['dm'];
mysql_select_db($database_conner, $conner);

$query_dmstore = "SELECT * FROM dmrmst";
$dmstore = mysql_query($query_dmstore, $conner) or die(mysql_error());

$totalRows_dmstore = mysql_num_rows($dmstore);
echo "Total number of stores: ". $totalRows_dmstore ." \n";

while($row_dmstore = mysql_fetch_array($dmstore)){
$query_store = "SELECT * FROM pog_check WHERE storenum = ". $row_dmstore['store'] ."";
$store = mysql_query($query_store, $conner) or die(mysql_error());

$projects_array = array(); //<--- you can reset it here
while($row_store = mysql_fetch_array($store)){
$projects_array[] = $row_store['pog_type'];
}
$string = implode(", ", $projects_array);

echo "Store#". $row_dmstore['store'] ." = ". $string ." \n";

unset($projects_array); //<---- OR you can reset it here.
}
?>[/code]

piznac · January 30, 2007

Ok Im a dummy,.. lol ;D

[code]$projects_array[] = $row_store['pog_type'];[/code]

Thanks for all the help!!!!!

boo_lolly · January 30, 2007
