Get summed value from specific rows - php

I have this:
$result = mysqli_query($mysqli, "SELECT balance FROM " . MYSQLBTCTABLE . " WHERE address='" . $_POST['address'] . "' LIMIT 1");
while($row = mysqli_fetch_assoc($result)) {
$balance = $row['balance'];
echo "<font style='font-weight:bold;'>Your current balance is: </font><br/>";
printf("%0.8f", ($balance / 100000000));
but it gets only the last value I need to find all balances from that address and sum them in total for the $balance.

Remove limit 1 and do the sum
$result = mysqli_query($mysqli, "SELECT balance FROM " . MYSQLBTCTABLE . " WHERE
address='" . $_POST['address'] . "' ");
$balance = 0;
while($row = mysqli_fetch_assoc($result)) {
$balance += $row['balance'];
echo "<font style='font-weight:bold;'>Your current balance is: </font><br/>";
printf("%0.8f", ($balance / 100000000));

Use
$balance += $row['balance'];

Use agregation:
$result = mysqli_query($mysqli, "SELECT sum(balance) FROM " . MYSQLBTCTABLE . " WHERE address='" . $_POST['address'] . "' GROUP BY address");

Remove the LIMIT out of the query and add SUM
$result = mysqli_query($mysqli, "SELECT SUM(balance) as totalBalance FROM " . MYSQLBTCTABLE . " WHERE address='" . $_POST['address'] . "'");
$row = mysqli_fetch_assoc($result);
$balance = $row['totalBalance'];
echo "<font style='font-weight:bold;'>Your current balance is: </font><br/>";
printf("%0.8f", ($balance / 100000000));

First of all,instead :
$balance = $row['balance'];
use:
$balance += $row['balance'];
Furthermore, get rid of the "LIMIT 1" constraint

How to show records between Dates in search?

It only shows 'No record found' but I'm trying to show the records between the dates using search
<?php
$query = "SELECT title, count(title) as totalnotary , notary_date, book_no
FROM tbl_notary ";
// Date filter
if (isset($_POST['search'])) {
$fromDate = $_POST['fromDate'];
$endDate = $_POST['endDate'];
if (!empty($fromDate) && !empty($endDate)) {
$query = "SELECT title, count(title) as totalnotary ,
notary_date, book_no
FROM tbl_notary
Where 1
and notary_date between '" . $fromDate . "' and '" . $endDate . "'";
}
}
// Sort
$query .= " group by book_no,title,Year(notary_date),
month(notary_date),day(notary_date)
ORDER BY notary_date DESC";
$Records = mysqli_query($conn, $query);
// Check records found or not
if (mysqli_num_rows($Records) > 0) {
while ($Record = mysqli_fetch_assoc($Records)) {
$book_no = $Record['book_no'];
$title = $Record['title'];
$totalnotary = $Record['totalnotary'];
$notary_date = date("F j,Y", strtotime($Record['notary_date']));
echo "<tr>";
echo "<td>" . $book_no . "</td>";
echo "<td>" . $title . "</td>";
echo "<td>" . $totalnotary . "</td>";
echo "<td>" . $notary_date . "</td>";
echo "</tr>";
}
} else {
echo "<tr>";
echo "<td colspan='4'>No record found.</td>";
echo "</tr>";
}
?>
OK, so you are saying that here is your problem.
$query = "SELECT title, count(title) as totalnotary , notary_date, book_no
FROM tbl_notary
Where 1 //!!!!!What is this 1???? You are missing a column name probably
and notary_date between '" . $fromDate . "' and '" . $endDate . "'";
Try this query. You have WHERE 1 which can't do anything and probably is failing your query. Try with some error reporting and you will probably get an error there.
$query = "SELECT title, count(title) as totalnotary , notary_date, book_no
FROM tbl_notary
WHERE notary_date BETWEEN '" . $fromDate . "' AND '" . $endDate . "'";
Then put this below to see if query is failing or not.
$Records = mysqli_query($conn, $query) or die (mysqli_error($conn));

Updating value into database

I have problem in updating the value into my database. The problem here is that the when i am updating the data for all rows, the data from last row will be updated into the first row. Other rows will not be updated including the last row.
Below is my code for updating...
$sql = "SELECT * FROM product where username = '$username'";
$result = mysqli_query($con, $sql) or die(mysqli_error($con));
$rows = mysqli_fetch_array($result);
$id = $rows['pro_id'];
$boxid = $rows['box_id'];
$name = $_POST['pro_name'];
$quan = $_POST['pro_quan'];
$sold = $_POST['pro_sold'];
for ($i = 0; $i < count($_POST['pro_name']); $i++)
{
$sql = "UPDATE product
SET pro_name = '" . $name[$i] . "',
pro_quan = " . $quan[$i] . ",
pro_sold = " . $sold[$i] . "
WHERE pro_id = " . $id . "
AND box_id = '" . $boxid . "' ";
$results=mysqli_query($con, $sql);
}
So, i have no ideas what have gone wrong. Thanks for helping
You need to place the result in a loop.
Something like that:
$sql = "SELECT * FROM product where username = '$username'";
$result = mysqli_query($con, $sql) or die(mysqli_error($con));
while ($rows = mysqli_fetch_array($result))
{
$id = $rows['pro_id'];
$boxid = $rows['box_id'];
$name = $_POST['pro_name'];
$quan = $_POST['pro_quan'];
$sold = $_POST['pro_sold'];
for ($i = 0; $i < count($_POST['pro_name']); $i++)
{
$sql = "UPDATE product
SET pro_name = '" . $name[$i] . "',
pro_quan = " . $quan[$i] . ",
pro_sold = " . $sold[$i] . "
WHERE pro_id = " . $id . "
AND box_id = '" . $boxid . "' ";
$results = mysqli_query($con, $sql);
}
}

Cant get table to update, delete and add with an extra code

So What Im trying to do is have the user add a code to a form, and fill the form out, A to add to the table, D to delete, U to update... The delete isnt working, neither is the insert, is it my logic? also I want to print the table only once, and sometimes it does it twice... any advice?
$Code=$_POST["Code"];
if ($Code == "A")
{
$sql = "INSERT INTO movieDATA values ('$idno', '$Name', '$Genre', '$Starring', '$Year', '$BoxOffice')";
$result= mysqli_query($link,$sql) or die(mysqli_error($link));
$showresult = mysqli_query($link,"SELECT * from movieDATA") or die("Invalid query: " . mysqli_error($link));
while ($row = mysqli_fetch_array($showresult))
{
echo ("<br> ID = ". $row["IDNO"] . "<br> NAME = " . $row["Name"] . "<br>");
echo("Genre = " . $row["Genre"] . "<br> Starring = " . $row["Starring"] . "<br>");
echo("Year = " . $row["Year"] . "<br> Box Office = " . $row["BoxOffice"] . "<br>");
}
}
elseif ($Code == "D")
{
$sql = "DELETE FROM movieDATA WHERE IDNO = '$idno'";
$result= mysqli_query($link,$sql) or die(mysqli_error($link));
$showresult = mysqli_query($link,"SELECT * from movieDATA") or die("Invalid query: " . mysqli_error($link));
while ($row = mysqli_fetch_array($showresult))

$result= mysqli_query($link,$sql) or die(mysqli_error($link));
$showresult = mysqli_query($link,"SELECT * from movieDATA") or die("Invalid query: " . mysqli_error($link));
while ($row = mysqli_fetch_array($showresult))
{
echo ("<br> ID = ". $row["IDNO"] . "<br> NAME = " . $row["Name"] . "<br>");
echo("Genre = " . $row["Genre"] . "<br> Starring = " . $row["Starring"] . "<br>");
echo("Year = " . $row["Year"] . "<br> Box Office = " . $row["BoxOffice"] . "<br>");
}

PHP is updating a database index that doesn't exist

On my main page, when someone signs-in, i have jQuery using AJAX to 'talk' to a PHP file, and the same for when they sign-out. But, when they sign out, it is supposed to update a database index with the time they left. If they database entry for their last name doesn't exist (meaning, they didn't sign-in), it is supposed to return an error. Instead, the PHP file is saying that it IS updating a non-existant database index. i am using IF statements to achieve this. and for some reason it thinks the index does exist. I've checked the database that it is writing to and the indexes it's supposed to be updating don't exist.
Here's my code:
if ($Type == 1)
{
$mysqli = new mysqli("localhost","----","----", "----");
if (!$mysqli)
$Type = 3;
$Select = $mysqli->query("SELECT Time_Out FROM " . $Date . " WHERE Last_Name = '" . $LName . "'");
$Row = $Select->fetch_assoc();
$Row2 = $Row['Time_Out'];
if ($Row2 !== "-1") $Type = 4;
if ($Type == 1)
{if ($mysqli->query("UPDATE " . $Date . " SET Time_Out='" . $Time . "' WHERE Last_Name='" . $LName . "'"))
{}
else
{$Type = 5;}
}
$Select = $mysqli->query("SELECT Time_In FROM " . $Date . " WHERE Last_Name='" . $LName . "'");
$Row = $Select->fetch_assoc();
$Row2 = $Row['Time_In'];
$Time2 = explode(":",$Row2);
$Hour2 = $Hour - $Time2[0];
if ($mysqli->query("SELECT Hours FROM Names WHERE Last_Name='" . $LName . "'"))
{$Select = $mysqli->query("SELECT Hours FROM Names WHERE Last_Name='" . $LName . "'");
$Row = $Select->fetch_assoc();
$Row3 = $Row['Hours'];
$Auto += 1;}
$Time3 = 60-$Time2[1];
if ($Hour != 21) $Time4 = $Min;
$Time5 = $Time3+$Time4;
if ($Time2[0]+1 != $Hour)
{$Time5 = $Time5+60;}
$Total = $Time5+intval($Row3);
if ($Type == 1)
{
if ($mysqli->query("UPDATE Names SET Hours = '" . $Total . "' WHERE Last_Name = '" . $LName . "'"))
{$Auto += 1;}
else
{$mysqli->query("INSERT INTO Names (Last_Name, First_Name, Hours) VALUES ('" . $LName . "', '" . $FName . "', '" . $Total . "')");}
}
$mysqli->close();
}
if ($Type == 1) echo "Thank you " . $FName . " " . $LName . " for signing out! See you next time!";
if ($Type == 2) echo "The entered Student ID# is invalid. Please try again!";
if ($Type == 3) echo "An unexpected error has occured. Please try again!";
if ($Type == 4) echo "You have already signed out today!" . $Auto;
if ($Type == 5) echo "You didn't sign in today.";
The UPDATE sql statement will return true, even if it doesn't find any matches (it still runs correctly, it just updates 0 rows).
Change this:
if ($Type == 1)
{if ($mysqli->query("UPDATE " . $Date . " SET Time_Out='" . $Time . "' WHERE Last_Name='" . $LName . "'"))
{}
else
{$Type = 5;}
}
To this:
if ($Type == 1) {
if ($mysqli->query("SELECT * FROM " . $Date . " WHERE Last_Name='" . $LName . "'")->num_rows > 0)
$mysqli->query("UPDATE " . $Date . " SET Time_Out='" . $Time . "' WHERE Last_Name='" . $LName . "'");
else
$Type = 5;
}
You run the select query to first determine if the record exists (if num_rows property of the result is > 0) and based on that either update the record or set your return value to 5.

Filtering MYSQL results by date

We have a script that generate invoice once a month (cron). But we would like to add feature, that we would be able to select date range "from - to" and then generate invoice only for the date selected.
I guess making input fields with calendar pop-up isn't hard, but filtering with PHP is a bit bigger challenge, so if anyone want to take a look at my code and give me some tips, I would be grateful.
function genInvoice($clientID, $orderID=0, $paid=false)
{
if($orderID == 0)
$sql = "select tblorders.* from tblorders,tblusers where invoiceid=0 and tblorders.userid=tblusers.id " .
"and status='closed' and tblusers.clientid=" . $clientID;
else
$sql = "select tblorders.* from tblorders,tblusers where invoiceid=0 and tblorders.userid=tblusers.id " .
"and tblusers.clientid=" . $clientID . " and tblorders.id=" . $orderID;
$res = full_query($sql) or die(mysql_error());
// If no closed orders uninvoiced, just return
if(!mysql_num_rows($res))
return 0;
$amount = 0;
$orders = array();
while($row = mysql_fetch_array($res, MYSQL_ASSOC))
{
// print_r($row);
// print "<br><hr>";
$amount += $row['amount'];
$orders[] = $row['id'];
}
$date = date("Y-m-d");
$status = $paid ?'Paid' : 'Unpaid';
$sql = "insert into tblinvoices (clientid, date, duedate, subtotal, total, status) values (" . $clientID . ",'" . $date .
"','" . $date . "'," . $amount . "," . $amount . ",'" . $status . "')";
$res = full_query($sql) or die(mysql_error());
$invoiceid = mysql_insert_id();
$sql = "update tblorders set invoiceid=" . $invoiceid . " where id in (" . implode(",", $orders) . ")";
$res = full_query($sql) or die(mysql_error());
$sql = "select tblorders.id as ReportID, FirstName, LastName, SearchName, CountyID, StateID, bl_orderitems.userid, bl_orderitems.amount, " .
"bl_orderitems.notes from tblorders, bl_orderitems left join bl_search on bl_search.id=packageid where tblorders.id in (" .
implode(",", $orders) . ") and bl_orderitems.orderid=tblorders.id order by tblorders.id,bl_orderitems.id";
$res = full_query($sql) or die(mysql_error());
while($row = mysql_fetch_array($res, MYSQL_ASSOC))
{
if($row['CountyID'] != 0)
$locale = getCounty($row['CountyID']);
else if($row['StateID'] != 0)
$locale = getState($row['StateID']);
if($row['SearchName'] != "")
$description = mysql_real_escape_string($row['FirstName'] . " " . $row['LastName'] . " " .
$row['SearchName'] . " " . $locale . " (Order #" . $row['ReportID'] . ")");
else
$description = "Search Package: " . mysql_real_escape_string($row['notes'] . " (Order #" . $row['ReportID'] . ")");
$sql = "insert into tblinvoiceitems (invoiceid, userid, type, description, amount, duedate) values " .
"(" . $invoiceid . "," . $row['userid'] . ",'search','" . $description . "','" .
$row['amount'] . "','" . $date . "')";
// print $sql . "<br>";
full_query($sql) or die(mysql_error());
}
sendmessage ('Invoice Created', $invoiceid);
return $invoiceid;
}
not going to look through all that code, but filtering results by a date range is easy.
SELECT id FROM some_table WHERE some_date_field BETWEEN $first_date AND $second_date
