PHP - Struggling With Last Entry In Array In For Loop

I have to take over somebody else's project. So I have the combination of being a beginner, not understanding their code well, and not experienced with arrays. I'm in over my head.

I have an array passed to the page, that would be something like this:

Array ( [215] => [213] => 1 [212] => 2 [214] => )
the user chose 1 person in 213, and 2 people in 212

 and I basically need to break it apart to do math like this:

(#people x cost of 213 = totalcostA )  +  (# people x cost of 212 = totalcostB)   =  total

The broken down data goes into the database, and the total is used for the cart.

I've taken suggestions and gotten to this jumbled mess:
Code: [Select]
$ids = $_POST['workshop_id'];
print_r($_POST['participantqty']);
// the above shows the arrays  are sending to this page and printing correctly: Array ( [215] => [213] => 1 [212] => 2 [214] => )
foreach ($_POST['workshop_id'] as $id){
   $qty = $_POST['participatqty'][$id];
}

if(sizeof($_POST['workshop_id'])) {
// loop through array
$number = count($ids);
for ($i=0; $i<=$number; $i++)
{
    // store a single item number and description in local variables
    $itno = $ids[$i];
    $qty_insert = $qty[$i];

   

$query_insertItemWorkshop = "INSERT INTO tbl_registration_workshop (registration_id, workshop_id, regworkshop_qty) VALUES ('$reg_id', '$itno', '$qty_insert')";
$dberror = "";
$ret = mysql_query($query_insertItemWorkshop);
$query_selectAllItems_events = 'SELECT * FROM tbl_workshops where workshop_id = '.$itno;
@$result_all_events = mysql_query($query_selectAllItems_events);
@$numRows_all_events = mysql_num_rows($result_all_events);
@$num=mysql_num_rows($result_all_events);
@$z_row = mysql_fetch_array($result_all_events);
// I want the below to work, but it won't until I can figure out how to break it all down.
$qty_total=$qty_insert*$z_row['workshop_price'];
$total = $total + $qty_total;

   
    if ($ids[$i] <> '') {

// I want the info to also appear below, but  can't until I figure out how to break them down.

    echo $total_students;
echo "<tr><td valign=top><b>Description:</b> ". $z_row['workshop_title'] ."</td><td align='right' colspan='2' width=300 valign=top>" . $qty_insert . " at ". $z_row['workshop_price'] ." each: &nbsp;</td><td valign=top> $". $qty_total ."</td></tr>";

I suck with arrays, there I said it .  With that said, hopefully someone can help me here. I have two multi-dimensional arrays called $allteams and $chosenteams (the contents of which are listed below).  I simply want to compare them and make a new array of the items that are in the first array ($allteams) but NOT in the second array ($chosenteams). NOTE: I tried to use array_diff() but couldn't get it to work since they are multidimensional...

FYI, I'm also confused why the info appears to be listed twice but I think that just has to do with associative vs. numeric arrays (i.e. I think I just need to specify one and the amount info would be cut in half), but I'll research this more on my own as it seems like it has to be easy to find

$allteams

Array ( => Array ( => 1 [teamid] => 1 [1] => Philadelphia [teamcity] => Philadelphia [2] => Eagles [teamname] => Eagles ) [1] => Array ( => 2 [teamid] => 2 [1] => Dallas [teamcity] => Dallas [2] => Cowboys [teamname] => Cowboys ) [2] => Array ( => 3 [teamid] => 3 [1] => New York [teamcity] => New York [2] => Giants [teamname] => Giants ) [3] => Array ( => 4 [teamid] => 4 [1] => Washington [teamcity] => Washington [2] => Redskins [teamname] => Redskins ) [4] => Array ( => 5 [teamid] => 5 [1] => Detroit [teamcity] => Detroit [2] => Lions [teamname] => Lions ) [5] => Array ( => 6 [teamid] => 6 [1] => Minnesota [teamcity] => Minnesota [2] => Vikings [teamname] => Vikings ) [6] => Array ( => 7 [teamid] => 7 [1] => Green Bay [teamcity] => Green Bay [2] => Packers [teamname] => Packers ) [7] => Array ( => 8 [teamid] => 8 [1] => Chicago [teamcity] => Chicago [2] => Bears [teamname] => Bears ) [8] => Array ( => 9 [teamid] => 9 [1] => Tampa Bay [teamcity] => Tampa Bay [2] => Buccs [teamname] => Buccs ) [9] => Array ( => 10 [teamid] => 10 [1] => New Orleans [teamcity] => New Orleans [2] => Saints [teamname] => Saints ) [10] => Array ( => 11 [teamid] => 11 [1] => Carolina [teamcity] => Carolina [2] => Panthers [teamname] => Panthers ) [11] => Array ( => 12 [teamid] => 12 [1] => Atlanta [teamcity] => Atlanta [2] => Falcons [teamname] => Falcons ) [12] => Array ( => 13 [teamid] => 13 [1] => Seattle [teamcity] => Seattle [2] => Seahawks [teamname] => Seahawks ) [13] => Array ( => 14 [teamid] => 14 [1] => San Francisco [teamcity] => San Francisco [2] => 49ers [teamname] => 49ers ) [14] => Array ( => 15 [teamid] => 15 [1] => St. Louis [teamcity] => St. Louis [2] => Rams [teamname] => Rams ) [15] => Array ( => 16 [teamid] => 16 [1] => Arizona [teamcity] => Arizona [2] => Cardinals [teamname] => Cardinals ) [16] => Array ( => 17 [teamid] => 17 [1] => New York [teamcity] => New York [2] => Jets [teamname] => Jets ) [17] => Array ( => 18 [teamid] => 18 [1] => Miami [teamcity] => Miami [2] => Dolphins [teamname] => Dolphins ) [18] => Array ( => 19 [teamid] => 19 [1] => Buffalo [teamcity] => Buffalo [2] => Bills [teamname] => Bills ) [19] => Array ( => 20 [teamid] => 20 [1] => New England [teamcity] => New England [2] => Patriots [teamname] => Patriots ) [20] => Array ( => 21 [teamid] => 21 [1] => Baltimore [teamcity] => Baltimore [2] => Ravens [teamname] => Ravens ) [21] => Array ( => 22 [teamid] => 22 [1] => Cincinnati [teamcity] => Cincinnati [2] => Bengals [teamname] => Bengals ) [22] => Array ( => 23 [teamid] => 23 [1] => Pittsburgh [teamcity] => Pittsburgh [2] => Steelers [teamname] => Steelers ) [23] => Array ( => 24 [teamid] => 24 [1] => Cleveland [teamcity] => Cleveland [2] => Browns [teamname] => Browns ) [24] => Array ( => 25 [teamid] => 25 [1] => Houston [teamcity] => Houston [2] => Texans [teamname] => Texans ) [25] => Array ( => 26 [teamid] => 26 [1] => Tennessee [teamcity] => Tennessee [2] => Titans [teamname] => Titans ) [26] => Array ( => 27 [teamid] => 27 [1] => Jacksonville [teamcity] => Jacksonville [2] => Jaguars [teamname] => Jaguars ) [27] => Array ( => 28 [teamid] => 28 [1] => Indianapolis [teamcity] => Indianapolis [2] => Colts [teamname] => Colts ) [28] => Array ( => 29 [teamid] => 29 [1] => Denver [teamcity] => Denver [2] => Broncos [teamname] => Broncos ) [29] => Array ( => 30 [teamid] => 30 [1] => Kansas City [teamcity] => Kansas City [2] => Chiefs [teamname] => Chiefs ) [30] => Array ( => 31 [teamid] => 31 [1] => Oakland [teamcity] => Oakland [2] => Raiders [teamname] => Raiders ) [31] => Array ( => 32 [teamid] => 32 [1] => San Diego [teamcity] => San Diego [2] => Chargers [teamname] => Chargers ) )

$chosenteams

Array ( => Array ( => 2 [teamid] => 2 [1] => Dallas [teamcity] => Dallas [2] => Cowboys [teamname] => Cowboys ) [1] => Array ( => 3 [teamid] => 3 [1] => New York [teamcity] => New York [2] => Giants [teamname] => Giants ) )

Again, I just want to compare those two multi-dimensional arrays and end up with another array that only has the items that are in the first but NOT in the second.   So now I'm trying to do it the way below using simply "array_push" Code: [Select]
$remainingteams = array();
foreach($allteams as $teamname=> $value) {
if (in_array($teamname, $chosenteams)) {
} else {
array_push($remainingteams,$teamname);
}
}
My end result based on the way the arrays are in this example should be...

$remainingteams  (really the only difference is that the Cowboys and Giants info is gone)

Array ( => Array ( => 1 [teamid] => 1 [1] => Philadelphia [teamcity] => Philadelphia [2] => Eagles [teamname] => Eagles ) [3] => Array ( => 4 [teamid] => 4 [1] => Washington [teamcity] => Washington [2] => Redskins [teamname] => Redskins ) [4] => Array ( => 5 [teamid] => 5 [1] => Detroit [teamcity] => Detroit [2] => Lions [teamname] => Lions ) [5] => Array ( => 6 [teamid] => 6 [1] => Minnesota [teamcity] => Minnesota [2] => Vikings [teamname] => Vikings ) [6] => Array ( => 7 [teamid] => 7 [1] => Green Bay [teamcity] => Green Bay [2] => Packers [teamname] => Packers ) [7] => Array ( => 8 [teamid] => 8 [1] => Chicago [teamcity] => Chicago [2] => Bears [teamname] => Bears ) [8] => Array ( => 9 [teamid] => 9 [1] => Tampa Bay [teamcity] => Tampa Bay [2] => Buccs [teamname] => Buccs ) [9] => Array ( => 10 [teamid] => 10 [1] => New Orleans [teamcity] => New Orleans [2] => Saints [teamname] => Saints ) [10] => Array ( => 11 [teamid] => 11 [1] => Carolina [teamcity] => Carolina [2] => Panthers [teamname] => Panthers ) [11] => Array ( => 12 [teamid] => 12 [1] => Atlanta [teamcity] => Atlanta [2] => Falcons [teamname] => Falcons ) [12] => Array ( => 13 [teamid] => 13 [1] => Seattle [teamcity] => Seattle [2] => Seahawks [teamname] => Seahawks ) [13] => Array ( => 14 [teamid] => 14 [1] => San Francisco [teamcity] => San Francisco [2] => 49ers [teamname] => 49ers ) [14] => Array ( => 15 [teamid] => 15 [1] => St. Louis [teamcity] => St. Louis [2] => Rams [teamname] => Rams ) [15] => Array ( => 16 [teamid] => 16 [1] => Arizona [teamcity] => Arizona [2] => Cardinals [teamname] => Cardinals ) [16] => Array ( => 17 [teamid] => 17 [1] => New York [teamcity] => New York [2] => Jets [teamname] => Jets ) [17] => Array ( => 18 [teamid] => 18 [1] => Miami [teamcity] => Miami [2] => Dolphins [teamname] => Dolphins ) [18] => Array ( => 19 [teamid] => 19 [1] => Buffalo [teamcity] => Buffalo [2] => Bills [teamname] => Bills ) [19] => Array ( => 20 [teamid] => 20 [1] => New England [teamcity] => New England [2] => Patriots [teamname] => Patriots ) [20] => Array ( => 21 [teamid] => 21 [1] => Baltimore [teamcity] => Baltimore [2] => Ravens [teamname] => Ravens ) [21] => Array ( => 22 [teamid] => 22 [1] => Cincinnati [teamcity] => Cincinnati [2] => Bengals [teamname] => Bengals ) [22] => Array ( => 23 [teamid] => 23 [1] => Pittsburgh [teamcity] => Pittsburgh [2] => Steelers [teamname] => Steelers ) [23] => Array ( => 24 [teamid] => 24 [1] => Cleveland [teamcity] => Cleveland [2] => Browns [teamname] => Browns ) [24] => Array ( => 25 [teamid] => 25 [1] => Houston [teamcity] => Houston [2] => Texans [teamname] => Texans ) [25] => Array ( => 26 [teamid] => 26 [1] => Tennessee [teamcity] => Tennessee [2] => Titans [teamname] => Titans ) [26] => Array ( => 27 [teamid] => 27 [1] => Jacksonville [teamcity] => Jacksonville [2] => Jaguars [teamname] => Jaguars ) [27] => Array ( => 28 [teamid] => 28 [1] => Indianapolis [teamcity] => Indianapolis [2] => Colts [teamname] => Colts ) [28] => Array ( => 29 [teamid] => 29 [1] => Denver [teamcity] => Denver [2] => Broncos [teamname] => Broncos ) [29] => Array ( => 30 [teamid] => 30 [1] => Kansas City [teamcity] => Kansas City [2] => Chiefs [teamname] => Chiefs ) [30] => Array ( => 31 [teamid] => 31 [1] => Oakland [teamcity] => Oakland [2] => Raiders [teamname] => Raiders ) [31] => Array ( => 32 [teamid] => 32 [1] => San Diego [teamcity] => San Diego [2] => Chargers [teamname] => Chargers ) )

Can anyone help me figure this out?  i've been trying for hours (I know, that's pathetic )

I have forum options in a loop (ie value = Entry$i)

I need to call GET_POST('Entry$i') and loop though the INSERT query $i times. If I put GET_POST in a loop, however, it does not work. It does not give an INSERT failed error so I assume it is not reading it. I have also tried putting if GET_POST('Entry1') outside the loop, but it does not like it. I dont know how many options are needed so I need it to generate the correct number. Then you can select $i options from duplicated option lists.  (Ie) participant 1,  2 and 3 from a list of possibles. 

I have also use GET_POST, I use a function. Other sumbits (I not use what they are called, please set me know), work fine on this page.

Code: [Select]

echo "Entry $Number: <select name = \"Entry$j\">";

for ($i = 1; $i<$EntNum+1; $i++)
{ etc etc

then
for ($i = 0; $i<$NumberOfEntrys; $i++) {
if (isset($_POST['AddEntry']) && isset($_POST["Entry$i"]))

//rest of this bit not executed -just insert
Ideas? Thanks

Code: [Select]
$db_connect = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

$sql_get = "SELECT DISTINCT category FROM con";

$sql_run = mysqli_query($db_connect, $sql_get) or mysqli_error($db_connect);

$sql_assoc = mysqli_fetch_assoc($sql_run);

while($sql_assoc = mysqli_fetch_assoc($sql_run)){
   
    echo $sql_assoc['category'];
}

From the column "category" I get printed 5 distinct entries, though the SQL statement itself does print out 6 distinct entries in MySQL, which is the right one.

Just wondering why does the while loop leave out one entry?

Also in the array is the "category" identifier necessary since it is identified in the SQL statement already? How would it look differently?

Can anyone tell me what's making  this code put an extra entry in the database?Whatever the number of looped students being added, it adds another row with nothing but the registrationid entered.
