I want to get a values group_by 'recivedID' but not working fine. find value only one first value is show on form how show all add all values and show.
table 'fuel_transaction'
recivedID hsdltrs
1 500
1 600
1 300
2 100
2 600
result show on form // no need
recivedID ->1
hsdltrs ->500 //worng result
I need result
//hsdltrs ->500+600+300=1400
recivedID ->1
hsdltrs ->1400
<?php
//$this->db->Select SUM(ABS(hsdltrs)) as Data ; //error please check its sir
$this->db->where('issuedate >=',$date1);
$this->db->where('issuedate <=',$date2);
$this->db->where('recivedID',$a);
$this->db->group_by('recivedID');
$queryb = $this->db->get('fuel_transaction');
if ($queryb->num_rows() > 0)
{
foreach ($queryb->result() as $rowc)
{
$tdate = $rowc->issuedate;
$hsdltrs = $rowc->hsdltrs;
$hsd += $rowc->hsdltrs;
?>
You need to add select_sum.
Then, inside your foreach it will be available using $rowc->sumhsd:
$this->db->select_sum('hsdltrs', 'sumhsd'); //Here it comes
$this->db->where('issuedate >=',$date1);
$this->db->where('issuedate <=',$date2);
$this->db->where('recivedID',$a);
$this->db->group_by('recivedID');
$queryb = $this->db->get('fuel_transaction');
if ($queryb->num_rows() > 0) {
foreach ($queryb->result() as $rowc) {
$tdate = $rowc->issuedate;
$hsdltrs = $rowc->sumhsd; //Here you get the sum

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.
id timing temp temp1 temp2 temp3
5260 1446746934 -76 -15 4 25
5259 1446746332 -75 -14 5 25
5258 1446745731 -77 -15 6 25
I have database like this. And I wrote the code below to get the row value out from my database. I would like to get the data from the previous points. Right now, I only get the latest point -76 from temp column. How to get the data from previous points like -75 or -77 at one column ??
$qryd = "SELECT id, timing, temp,temp1,temp2,temp3 FROM tempArray WHERE timing>='$dlimit' ORDER BY id ASC LIMIT 1008;
$i=0;
$r = mysql_query($qryd);
$count = mysql_num_rows($r);
while($row=mysql_fetch_array($r, MYSQL_ASSOC)) {
$tid=$row['id'];
$dt = $row['timing'];
$te = $row['temp'];
$return="[$dt, $te],";
echo $return;
$i++;
}
echo $te;
//the result is -76
Try this:
$qryd = "SELECT id, timing, temp,temp1,temp2,temp3 FROM tempArray";
$i=0;
$r = mysql_query($qryd);
$count = mysql_num_rows($r);
while($row=mysql_fetch_array($r, MYSQL_ASSOC)) {
$tid=$row['id'];
$dt = $row['timing'];
$te = $row['temp'];
$return="[$dt, $te],";
echo $return;
$i++;
echo $te;
}
The "echo $te" was outside the loop, so the result was complete but your code prints only the last record returned by the query execution.
The best way I can do is to do more code on my database site to grab data one by one. I know it is not the right way to do it. But at least it is the best I can do to my program.
I have the following query:
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND() LIMIT 4");
while ($po = $trabajos->fetch_array()) {
$trab[] = $po;
}
This query is working fine, but, it shows only 4 records, but then again in another part of the same page I need the same table information but I don't want it to be limited, say I want 10 instead of only 4. so.
Section Header
Section Slider <-- here only shows 4 items as intended
Using a foreach as follow:
foreach ($trab as $it) {
// My html Code
}
Section Mid Body some info
Section Main Body More info
Section Mid End Footer <-- here I need the same information as in the slider section but with a different layout instead of only 4 items I need 10 items.
For that last item I have to open another query similar as before.
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND() LIMIT 10");
while ($po = $trabajos->fetch_array()) {
$trab[] = $po;
}
So I was thinking is there a way to use:
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND()");
while ($po = $trabajos->fetch_array()) {
$trab[] = $po;
}
That query without the LIMIT and instead Limit the foreach to only fetch the first 4 rows or is there a way to use that query with the LIMIT but instead of 4 or 10, say I use 20, and for the first foreach only display the first 4 and for the second foreach show the rest after the first 4.
The main idea is not have more than 1 query for the same information.
this will exit a loop, but why not query 10 records, build your results, all 10 and then just output 4 of them, there and all 10 over yonder.
$x = 0;
foreach ($trab as $it) {
if($x == 5){
break; //will exit loop as will return.
}
// My html Code
++$x;
}
This will work with any kind of loop, you can also use continue to skip to the next pass of the loop
foreach ($trab as $it) {
if($x < 5){
continue; //code below here wont run until $x >= 5.
}
// My html Code
++$x;
}
i'm not sure to understand exactly what you want, but if you want to divide your array in 2 part. You can use a counter
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND() LIMIT 20");
$i = 0;
$trab2 = new Array();
while ($po = $trabajos->fetch_array()) {
if($i < 4) {
$trab[] = $po;
} else {
$trab2[] = $po;
}
$i++;
}
First, RAND() is horrible since it essentially disables MySQL’s built in caching with each run of the query. But there is no best way for me to advise how to get around that based on your script’s requirements. So just keep that in mind. But here is what I would recommend.
That query without the LIMIT and instead Limit the foreach to only
fetch the first 4 rows or is there a way to use that query with the
LIMIT but instead of 4 or 10, say I use 20, and for the first
foreach only display the first 4 and for the second foreach show
the rest after the first 4.
Yes, just use array_slice like this:
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND() LIMIT 20");
while ($po = $trabajos->fetch_array()) {
$trab[] = $po;
}
$trab_slice_1_size = 4;
$trab_slice_2_size = 10;
$trab_slice_1 = array_slice($trab, 0, $trab_slice_1_size);
$trab_slice_2 = array_slice($trab, $trab_slice_1_size, $trab_slice_2_size);
The nice thing about array_slice is you can cleanly select a start & end point. In my example I set the sizes in variables. Which makes it easier to adjust in your code if you somehow want to dynamically change values.
The easiest way is to use a counter variable:
function fetch_items($limit=10) {
public $trabajos,$trab;
$count=0;
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND()");
while (($po = $trabajos->fetch_array()) && ($count<$limit)) {
$count++;
$trab[] = $po;
}
}
If you call fetch_items() without a parameter, it defaults to 10 or less. If you specify a parameter it loads the array with up to the amount you specify. You could also have the function return the value of $count so you know how many were returned.
try;
$trabajos = $con->query("SELECT * FROM portafolio ORDER BY RAND() LIMIT 10");
$i = 0;
while ($i < 5 && $po = $trabajos->fetch_array()) {
.....
.....
$i++;
}
then, if you want to re-use the data,
mysql_data_seek($trabajos, 0);
$i = 0;
while ($i < 11 && $po = $trabajos->fetch_array()) {
.....
.....
$i++;
}
I have a table in my database. I want to get ltotal value from leave table, and then count all of ltotal. Here are my query and code I use:
$annual_query = pg_query("select ltotal from leave where lapplicant='adam' and ltype=2");
$annual_result = pg_fetch_array($annual_query);
if (pg_num_rows($annual_query) > 0) {
foreach ($annual_result as $data) {
$total_annual = $total_annual + $data;
}
print($total_annual);
}
There are 3 records in the table leave where lapplicant='adam' and ltype=2.
Each ltotal is 1.
When I tried to runprint($total_annual) the result is 2 (it must be 3).
Then I tried to print_r($annual_result['ltotal']), the results is just 1 (it must be 1,1,1).
Can anyone help me? Thank you.
pg_fetch_array() returns just one row with numeric and associative keys (same value twice when traversed). You should use pg_fetch_all() and traverse or use while loop on consecutive rows.
$total_annual = 0;
$annual_query = pg_query("select ltotal from leave where lapplicant='adam' and ltype=2");
while ($row = pg_fetch_array($annual_query)) {
$total_annual = $total_annual + $row['ltotal'];
}
print($total_annual);
or
$total_annual = 0;
$annual_query = pg_query("select ltotal from leave where lapplicant='adam' and ltype=2");
$annual_result = pg_fetch_all($annual_query);
foreach ($annual_result as $row) {
$total_annual = $total_annual + $row['ltotal'];
}
print($total_annual);
Tamil pointed out the immediate problem. However - why don't you just do this in SQL?
select sum(ltotal)
from leave
where lapplicant='adam' and ltype=2
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
