I have a Product master in which I have 2 fields, ONE is for Main Product (Field name 'Under') and SECOND is for Sub-product (Field name is 'Prod_desc)
What I want is a nested loop where I capture all codes (field name is Cylno) from transaction Table (ECR_CBDC).
I have 2 nested loops, First while loop is for PRODUCT_MASTER where based on user selection of a Main-product the sub-products are selected and SECOND loop is for collecting the codes for all sub-products.
Now the issue is it collects only 1 value as the FOR loop overwrites the previous value. Is there any other loop which can hold the previous value of each sub-product.
$p=mysql_query("SELECT * FROM PRODMAST WHERE Under='$product'");
while ($p2=mysql_fetch_assoc($p))
{
$prodesc=$p2['Prod_desc'];
$dc=mysql_query("SELECT * FROM ECR_CBDC WHERE Prod_desc='$prodesc' AND usr='$user'");
$num_rows = mysql_num_rows($dc);
$fill_from_array = array(); /* as "value"=>"option" */
for($i = 1; $i <= $num_rows; $i++)
{
$row = mysql_fetch_assoc($dc);
$fill_from_array[$row['Cylno']] = $row['Cylno'];
}
}
If I understand what you're asking - $fill_from_array only collects one row's worth - I think you need to define $fill_from_array outside of the first loop, so...
$p=mysql_query("SELECT * FROM PRODMAST WHERE Under='$product'");
$fill_from_array = array(); /* as "value"=>"option" */
while ($p2=mysql_fetch_assoc($p))
{
$prodesc=$p2['Prod_desc'];
$dc=mysql_query("SELECT * FROM ECR_CBDC WHERE Prod_desc='$prodesc' AND usr='$user'");
$num_rows = mysql_num_rows($dc);
for($i = 1; $i <= $num_rows; $i++)
{
$row = mysql_fetch_assoc($dc);
$fill_from_array[$row['Cylno']] = $row['Cylno'];
}
}
That way it's not over-writing $fill_from_array each time the while() loop loops. Is that what you mean?
Instead of emulating a join in code, use the JOIN syntax instead to reduce the number of loops and data transfer:
SELECT * FROM PRODMAST
INNER JOIN ECR_CBDC ON PRODMAST.Prod_desc=ECR_CBDC.Prod_desc AND usr='$user'
WHERE Under='$product'

I am trying to create a number of arrays to add to a larger array which I will then index two dimensionally (for example my_array[i][j]).
I believe I am having some type of pointing issue... I am iterating through a loop.... at the top of each iteration I instantiate a new array with the same name. When I try and view the output each item in the array appears blank.
Is there a better way for me to instantiate the "temp" arrays to fill the larger (outer) array? Really appreciate any and all help, this community has helped me through so many questions :D
$main_array = array();
for($i = 0; $i < $member_count; $i++)
{
$temp_array = array();
//preform SQL query here
$sql_get_member_transactions = 'some SQL query to go to my DB';
foreach($sql_get_member_transactions as $row)
{
//cannot get array to update here
array_push($temp_array, $row['amount']);
}
array_push($main_array, $temp_array);
}
#***FULL CODE BELOW***
$club_transactions = array();
for($i = 0; $i < $member_count; $i++)
{
#create an array for each member in the club,
#add each memeber's array to a larger array once filled with deposit amounts
#here check if member had a deposit (later we will check ALL transaction types...)
#if no deposit on that date add a zero to their array
$temp_member_transactions = array();
$temp_member = my_members[$i];
$sql_member_transactions = "SELECT * FROM Transactions WHERE Date >= '$first_t_date' AND Date <= '$last_t_date' AND RelatedClubID = 'THH'";
$sql_get_member_transactions = mysqli_query($conn, $sql_member_transactions);
//here we will get all transactions that lie within the
//event-transaction-date-window... in otherwords, the date window
//in the year where members transactions occured
foreach($sql_get_member_transactions as $row)
{
//we only want to include the transaction amount
//in the member-specific array if it belongs to that member
//otherwise see "else"
if($row['T_Owner'] == $temp_member)
{
$z = $row['T_Amount'];
}
else
{
//set to 0 so that we still account for the transaction date
$z = 0;
}
array_push($temp_member_transactions, $z);
}
array_push($club_transactions, $temp_member_transactions );
The issue is not how I am generating the number, that is working fine for a different app I have. The issue is counting the total number of boxes and iterating through a forloop that many times. Right now I am multiplying box_ct * qty_ord to get the total boxes. BTW, I am still trying to understand everything I can do with foreach and for loops, so if anyone has a better idea, Great.
CLARIFICATION: I am searching the database by order number and pulling back qty_ord, box_ct, and item_no for each. On some orders there is more than one item. So for each item I need to multiply qty_ord by box_ct = count and for that specific item I need to iterate through the loop based on what my count is.Right now if I remove the foreach and hardcode the for loop count variable it works fine. Any ideas on what is wrong with my foreach?
qty_ord | box_ct | item_no
------------------------
1 2 10001
3 3 10002
2 1 10003
2 3 10004
2 6 10005
Below is my code.
$sql ="SELECT imitmidx_sql.box_ct, oeordlin_sql.item_no, oeordlin_sql.qty_ord
FROM imitmidx_sql
JOIN oeordlin_sql ON oeordlin_sql.item_no = imitmidx_sql.item_no WHERE ord_no ='$orderNum'";
$query = odbc_exec($conn, $sql);
$row7 = odbc_fetch_array($query);
foreach($row7['item_no'] as $item){
$count = $row7['qty_ord'] * $row7['box_ct'];
for($counter = 0; $counter <= $count; $counter++){
//GRAB NUMBER FROM FILE
$sscc = file_get_contents("ucc128.txt");
//INCREMENT NUMBER
$sscc++;
//PUT THE NUMBER BACK IN FILE
$sscc = file_put_contents("ucc128.txt", $sscc);
//COMBINE STATIC NUMBER AND NUMBER FROM FILE
$ssccnumber = "00950000".$sscc;
//CREATE CHECK DIGIT MATH
$ssccnumArray = str_split((string)$ssccnumber);
$ssccstep1 = array_combine(range(1, count($ssccnumArray)), $ssccnumArray);
$ssccstep2 = 0;
$ssccstep4 = 0;
foreach($ssccnumArray as $k => $v){
if($k%2){
$ssccstep2 += (int)$v;
}else{
$ssccstep4 += (int)$v;
}
}
$ssccstep3 = (int)$ssccstep2 * 3;
$ssccstep5 = (int)$ssccstep3 + (int)$step4;
$ssccCheckDigit = (ceil($ssccstep5 / 10) * 10) - $ssccstep5;
//END CREATE CHECK DIGIT
//CONCATENATE FULL NUMBER
$sscc1 = $ssccnumber.$ssccCheckDigit;
$sql = "INSERT INTO ucc128 (sscc, ord_no) VALUES ('$sscc1' ,'$orderNum')";
#echo $sql.'<br />';
odbc_exec($connPRONUMBER, $sql);
}
}
I believe your issue may be with the following:
foreach($row7['item_no'] as $item){
$count = $row7['qty_ord'] * $row7['box_ct'];
//...
}
This should be:
foreach($row7['item_no'] as $item){
$count = $item['qty_ord'] * $item['box_ct'];
//...
}
You are grabbing data from the query results, as opposed to the current row.
My foreach was not working, so what I did instead was get the sum using my SQL query.
SELECT SUM(imitmidx_sql.box_ct * oeordlin_sql.qty_ord) AS total
FROM imitmidx_sql
JOIN oeordlin_sql ON oeordlin_sql.item_no = imitmidx_sql.item_no WHERE ord_no ='$orderNum'
I was then able to ouput it and save $row7['total'] to the variable $count.
$st = $this->db->prepare("SELECT * FROM invoices WHERE group_id=?");
$st->execute(array($id));
if($st->rowCount() >= 1){
foreach ($st as $row) {
$counter = $row["paymentAmount"];
$start = 1;
for($start; $start < $st->rowCount(); $start++) {
$counter = $counter + $row["paymentAmount"];
}
}
It actually print out $row["paymentAmount"] + $row["paymentAmount"] and so on, depending on how many $row["paymentAmount"] there is. But the problem is that the last output from $row["paymentAmount"] is 2500.
There is:
10000
10000
2500
And the result is: 7500
I want it to be: 22500
And if the last result is 3000 it shall be 23000. So what I simply need is this code to take every row from the database, just not the latest one.
Edit: I want it outside of the SQL query
You don't need PHP logic for something like this. The functionality is built right into SQL.
SELECT SUM(paymentAmount) FROM invoices WHERE group_id=?
You should let your database handle the sum unless you have a legitimate reason why it needs to be handled in PHP. The database is more efficient with this type of operation and you avoid a loop in PHP.
SELECT SUM(paymentAmount) AS TotalPaymentAmount FROM invoices WHERE group_id = ?
You can then change your PHP to return just one row:
$row = $st->fetch();
echo $row["TotalPaymentAmount"];
If you need to do this calculation outside of SQL, just change your loop:
if($st->rowCount() >= 1){
//init the counter to 0 before you loop through your rows
$counter = 0;
//the foreach will iterate over your result set and add the paymentAmount to $counter.
foreach ($st as $row) {
$counter += $row["paymentAmount"];
}
//echo results outside of the loop
echo $counter;
}
If you need to code this outside SQL on purpose (e.g. because you need to do further processing for each row), then I'd code this as follows:
if ($st->rowCount() >= 1) {
$counter = 0;
foreach ($st as $row) {
$counter += $row["paymentAmount"];
}
}
I have a table containing user id with left node and right node (Both are which user id). I am trying to create a function to count all the right nodes and total nodes of a particular user id in PHP.
The Code I have written till now which is always returning 0 :
function allcount($id) //Function to calculate all children count
{
$sqlz = "SELECT * FROM user_transaction_details WHERE user_id = '$id'";
$execsql = mysqli_query($conn,$sqlz);
$array = mysqli_fetch_array($execsql);
echo $sqlz;
(array_count_values($array));
$count = 0;
echo $array['l_node'];
if(!empty($array['l_node']))
{
$count += allcount($array['l_node']) +1;
}
if(!empty($array['r_node']))
{
$count += allcount($array['r_node']) +1;
}
return $count;
}
Here is the table structure :

Can anybody please help.
You need to pass $conn as an argument or declare it as global inside the function, because otherwise it is not available inside the function.
Hi I'm currently querying from a database base user ids for a contest, However I want to avoid choosing duplicates in my results_array, this function getrandomspecies receives a array_result, this array results iterates 7 times. How test that I don't put duplicates in my results_array? I have gotten several duplicates.
function getrandomspecies($array_result){
//database connection
$dbn = adodbConnect();
foreach($array_result as $possible){
//query the results
$querys= "select * from taxonomic_units where tsn = $possible";
$resultss = $dbn -> Execute($querys);
while($rowss=$resultss->FetchRow()){
$id = $rowss['tsn']; //there ID
$ranksss = $rowss['rank_id']; //ranking id, I choose 220 and 230
if($ranksss == 220 || $ranksss == 230){
$prelimary_array[] = $id;
}
}
//grab random index
$index = array_rand($prelimary_array,1);
//put result id into a variable
$newspecies = $prelimary_array[$index];
//put that variable in an array
$results_array[] = $newspecies; //there is 7 newspecies/winners at the end, I dont want duplicates
}
return $results_array;
}
MySQL should be the following :
select distinct tsn, rank_id from taxonomic_units where tsn = $possible
But you should ideally use prepared statements.
what about this? You may do it with one query:
$querys= "select DISTINCT tsn from taxonomic_units where tsn IN (".implode(",",$array_result).") AND rank_id IN (220,230) ORDER BY RAND() LIMIT 7 ";
Loop your result array and if it does not exists add it. If you end up with less than 7, do your big loop again.
replace this line :
$results_array[] = $newspecies;
by:
$loop_1_more_time=0;
if (isset($results_array)){
foreach($results_array as $result){
if ($result == $new_specie){
$loop_1_more_time=1;
}
}
}
if ($loop_1_more_time == 0){
$results_array[] = $newspecies;
}
//there, if $loop_1_more_time equals 1, start again. To start again and be sure you have seven instead of 6 or less, You could replace your big first "foreach" loop with a "for" loop that depends of the count() of the $array_result, and the $array_result would be array_result[$i] instead of $possible. $i would start at 0 and increment at each end of loop. It would not be incremented if $loop_1_more_time==1;.
Example :
for ($i = 0; $i < count($array_result); $i++) {
//stuff
//if ($loop_1_more_time=1;) { $i--; }
}
Why don't you try shuffling the array, and then picking the first X numbers?
That way, rather than having to check the results array for duplicates, it will never come up in the first place
