How to fetch value from this MySQL query response in PHP - php

Below is my query. I have commented that I tried in code
$query = "SELECT SUM(paymentAmount) From salepayment WHERE adminUserId ='$adminUserId' AND invoiceId = '$salesInvoiceId' ";
$this->res = $this->db->prepare($query);
$this->result = $this->res->execute();
$countAmount = $this->res->rowCount();
if ($countAmount > 0) {
$sumOfPaymentAmount = $this->res->fetch(PDO::FETCH_OBJ);
echo json_encode($sumOfPaymentAmount);
// $totalPaid = $sumOfPaymentAmount->"SUM(paymentAmount)";
// echo json_encode($totalPaid);
}else{
$paid = 0;
}
Here is my response
{
"SUM(paymentAmount)": "350"
}
I want to get this value into the $paid variable.
Thanks for your help. I am a beginner at PHP and server-side coding so pardon me for my mistakes.

This should be able to be done by adding as paid after SUM(paymentAmount) in the query like so:
SELECT SUM(paymentAmount) as paid From...

How to save query in multidimesional array?

I have this script executing as a cron job everyday to update days remaining to pay invoices. I first query every row of my table and attempt to store the data in a multidimensional array but this seems to be storing everything I query in the first element of my array.
Here's my script:
<?php
include '../inc/dbinfo.inc';
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");
error_log( "################################################# UpdateVendorInvoiceDays.php #################################################" );
$three = 3;
$fetchAllInvoices = "SELECT VENDORINVOICEID, VdrInvoiceReceived, PaymentDue, COUNT(*), DATEDIFF(PaymentDue, NOW()) FROM tblVendorInvoices WHERE VdrInvoiceStatusID != ?";
$getInvoices = $conn->prepare($fetchAllInvoices);
$getInvoices->bind_param("i", $three);
$getInvoices->execute();
$result = $getInvoices->get_result();
$rows = array();
$j = 0;
while($row = $result->fetch_assoc())
{
$rows[$j][] = $row;
$j++;
}
echo json_encode($rows[0][0]); //Only outputs one row
//UPDATE DAYS REMAINING IN EACH ENTRY THAT ISNT PAID
$updateDaysRemaining = "UPDATE tblVendorInvoices SET DaysRemaining = ? WHERE VENDORINVOICEID = ? AND VdrInvoiceStatusID ! = ?";
$setDays = $conn->prepare($updateDaysRemaining);
$k = 0; //incrementor
$numberOfEntries = $rows['COUNT(*)'];
for($k;$k<$numberOfEntries;$k++){
$setDays->bind_param("iii", $rows[$k]["DATEDIFF(PaymentDue, NOW())"],
$rows[$k]['VENDORINVOICEID'], $three);
if($setDays->execute()){
error_log('Cron success');
}else{
error_log('Cron fail');
}
}
?>
Currently the output from my first query is:
[[{"VENDORINVOICEID":88,"VdrInvoiceReceived":"2018-08-21","PaymentDue":"2018-07-27","COUNT(*)":2,"DATEDIFF(PaymentDue, NOW())":-25}]]
and my error log only gives me a notice for $rows['COUNT(*)'] being undefined (which makes sense)
I've looked at other answers here but they don't seem to have the same structure as I do.
EDIT: I also have 2 rows in my database but this only puts out one. I forgot to mention this.
There are a couple of simplifications to get all of the rows. Instead of...
while($row = $result->fetch_assoc())
{
$rows[$j][] = $row;
$j++;
}
echo json_encode($rows[0][0]);
You can just return all rows using fetch_all()...
$rows = $result->fetch_all (MYSQLI_ASSOC);
echo json_encode($rows);
Then encode the whole array and not just the one element - which is what $rows[0][0] was showing you.
As for you other problem - change in your select statement to
COUNT(*) as rowCount
and then you can use this alias for the field reference...
$rows['COUNT(*)']
becomes
$rows['rowCount']

cannot select a row in mysql

EDIT1 : used double quotes and single quotes but I am getting same error.
EDIT2 : same query is returning me result in mysql shell
I am selecting a row from a table.
if(!isset($_GET['title']) || !isset($_GET['user'])){
echo "hi"; //something come here
}
else{
$title = $_GET['title'];
$title = mysqli_real_escape_string($conn,$title);
$user = $_GET['user'];
$user = mysqli_real_escape_string($conn,$user);
echo $title ;
echo $user ;
// tried giving value directly to test but no luck
$query = "SELECT * FROM site WHERE client=\"Chaitanya\" && title=\"werdfghb\" ";
$result5 = mysqli_query($conn,$query) or die(mysqli_error());
$count = mysqli_num_rows($result5);
echo $count ;
while($result9 = mysqli_fetch_array($result5)){
$kk=$result9['url'];
echo $kk ;
}
$page = $kk;
include ( 'counter.php');
addinfo($page);
}
In my database there is a row with columns title and client and the values I entered are in that row but when I echo count(no of rows) it is showing zero.
Is there anything wrong with code ?
The error you are getting is due to the line
$page = $kk;
in this code $kk is not declared previously. The defined $kk is in the while loop scope.
declare the variable like this in the outer scope from the while loop
...
$kk = null;
while($result9 = mysqli_fetch_array($result5)) {
$kk = $result9['url'];
echo $kk ;
}
$page = $kk;
...
Error on Fetching Data
You have to crack you SQl into smaller pieces and test the code like this.
run the query SELECT * FROM site without any where and get the count
run the query SELECT * FROM site WHERE client='Chaitanya' and get the count
SELECT * FROM site WHERE title='werdfghb' and check the count
Then run the whole query
And see the results. This way u can find out in where the issue is in your SQL code. I prefer you use the mysql client to execute this queries
As I pointed out in my comment, $kk is undefined in the $page = $kk;, since it is declared in the while loop.
Do something like:
$kk = ''; //can also do $kk=NULL; if you want.
while($result9 = mysqli_fetch_array($result5)) {
$kk=$result9['url'];
echo $kk ;
}
$page = $kk;
try this one
$client = "Chaitanya";
$title = "werdfghb";
$query="SELECT * FROM site WHERE client='".$client."' and title='".$title."' ";
you can also use this
$query="SELECT * FROM site WHERE client={$client} and title={$title} ";

Array and for each loop issues

Code is below if I run one value in the array the results are correct if I run more than one value the results are of the price is incorrect its like it has messed around with the values somewhere ?? help appreciated
$dido=array('42204131','22204131');
foreach($dido as $did):
$query = "select * from dispatch,link where lid=dlid and did=$did";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$vanc1=$row['vanc1'];
$vanc2=$row['vanc2'];
$vanc3=$row['vanc3'];
$vanc4=$row['vanc4'];

$tpriceanc3=$vanc3*$priceanc3;
}
// price anc4
$querypanc4 = "select pprice from products where pid=$anc4";
$resultpanc4 = mysql_query($querypanc4);
while($row = mysql_fetch_array($resultpanc4))
{
$priceanc4=$row[pprice];
$tpriceanc4=$vanc4*$priceanc4;

$qrygt="UPDATE dispatch SET gtprice=$gtprice WHERE did=$did";
$resultgt=#mysql_query($qrygt);
}
endforeach;
1) The only possible issue I could spot in your code, is that when some of your select pprice from products where pid ... queries do not return any data, you retain value of $tpriceancX from previous iteration.
2) Also (out of topic) you can replace your 5 blocks of repeated code with for loop.
$gtprice = 0;
for ($i = 1; $i <= 5; $i++)
{
$querypanc = "select pprice from products where pid=".$row["anc$i"];
$resultpanc = mysql_query($querypanc);
while($pancrow = mysql_fetch_array($resultpanc))
{
$priceanc=$pancrow[pprice];
$tpriceanc=$row["vanc$i"]*$priceanc;
$gtprice += $tpriceanc;
}
}
Your first and biggest problem is the copy-pasta nature of your code. Let's try and break down what you're doing:
Setting up a list of ids
Running a query on those ids
Putting the results into an array
Running a separate query on each of those results
You are also using some very janky syntax. (ie foreach($foo as $bar):).
Break these things down into methods. What is a method? It takes an input and transforms it into an output.
//returns an array of price information
public function getPrices($idArray) { //note the good method and parameter names!
//do stuff
}
Now that we know what we are doing, we can start to fill in the implementation details:
public function getPrices($idArray) {
foreach($idArray as $id) {
//somehow get the gross-scale information
//then put it in a data object
//then call a function to get specific information
}
}
What should that sub-method do? Lets look at your current code snippet:
// price anc1
$querypanc1 = "select pprice from products where pid=$anc1";//sets up sql query
$resultpanc1 = mysql_query($querypanc1); //runs the query
while($row = mysql_fetch_array($resultpanc1)) { //for each result
$priceanc1=$row[pprice]; //gets the price
$tpriceanc1=$vanc1*$priceanc1; //calculates some other price
}
Those last two lines really suggest an object but maybe that's too heavyweight for your purpose. The first two lines are boiler plate you repeat endlessly. Lets write a function!
public function getPrices($name, $pid, $multiplier) {
$sqlQuery = "SELECT pprice FROM products WHERE pid=$pid";
$result = mysql_query($sqlQuery);
$prices = array();
while ($row = mysql_fetch_array($result) {
$key = "price".$name;//$key will be something like 'priceanc1'
$prices[$key] = $row[pprice];
$tkey = "tprice".$name;
$prices[$tkey] = $prices[$key] * $multiplier;
}
}
Now, this function is a bit unclean because it tries to do two things at once (queries the database and then massages the data into a usable array) but I wanted it to resemble what you were doing. With this function written we can go back to our higher level function an call it:
public function getPrices($idArray) {
foreach($idArray as $id) {
$sqlQuery = "SELECT * from dispatch, link WHERE lid=dlid and did=$id";
$prices = array();
while ($row = mysql_fetch_array($result) {
for ($idx = 1; $idx <= 5; $idx++) {
$name = "anc".$idx;
$pid = $row[$name];
$multiplier = $row["vanc".$idx];
$priceArray = getPrices($name, $pid, $multiplier);
$prices = array_merge($prices, $priceArray);
}
}
}
//put a var_dump here to check to see if you're getting good results!
return $prices;//Should be the aggregated prices you've gotten from the db
}
Now, that is what you're attempting to do, but I admit I don't understand how your database is set up or what your variables actually mean. Pressing on! We also note that unnecessary massaging of data falls away.
You can call this like so:
$ids = array();
$ids[] = 42204131;
$ids[] = 22204131;
$prices = getPrices($ids);
var_dump($prices);//shows the result of your work
Now that you have the prices, you can pass them to another function to run the update:
updatePrices($prices);
I'll let you write that part on your own. But remember; break down what you're doing and have repeated elements be handled by the same function. The real lesson to learn here is that programming is really communicating: your code doesn't communicate anything because there is so much repeated noise. Use good variable names. Tighten what you're doing down to functions with single tasks. This way anyone reading your code (including you!) will know what you're trying to do and where you've gone wrong.

Variable in a mysql query

for ($i=0; $i<$count; $i++) {
$appid = $chk[$i];

</script>';
echo "$vehicle1";
}
Hi guys my problem here is that the $vehicle is not returning its values if it is inserted in a database query ($vquery = mysql_query("SELECT * FROM vehicletbl WHERE vehicle = '$vehicle1'");) but if it is echoed, it return its value. The logic here is that it will select all the values from vehicletbl wherein the value of any values in 'vehicle' column will be equal to the $vehicle1. Thanks for the help!
You've got ZERO error handling on your queries. Try adding some debugging to the query calls:
$result = mysql_query(...) or die(mysql_error());
The rest of the code is ugly, but looks "ok", so start looking at WHY you're not getting anything back from the queries.
Never ever assume a query succeeds.
try this to debug :
$sql = "SELECT * FROM vehicletbl WHERE vehicle = '" . $vehicle1 . "'";
$vquery = mysql_query($sql) or die(mysql_error() . "\n<br>$sql");
thats what i do to find errors in my sql.
Noob programmer ? Here are some things to know :
for ($i=0; $i<$count; $i++) {
$appid = $chk[$i];
// Replaced By ...
foreach($chk as $appid){
http://php.net/manual/en/control-structures.foreach.php
// Include the file before the loop ! You're including 20 times your file, but you just need to do it once ! Another thing to know:
include_once("dbconnect.php");
http://php.net/manual/en/function.include-once.php
$desti = "".$fetch['destination']." "." ".$fetch['location']."";
// WHY ?? Isn't that easier to do this ?
$desti = $fetch['destination']." ".$fetch['location'];
And security :
// Don't forget to escape your variables before putting it in mysql queries
$appid = mysql_real_escape_string($appid);
$selectquery = mysql_query("SELECT * FROM regform_admin WHERE tid = '$appid'");
Best way to defend against mysql injection and cross site scripting
There are other remarks, but try to improve those points first !

where clause not displaying data

i am trying to display data based on wether data in a field is new. instead of showing only the data that is new it is showing all data. can someone point out my error. many thanks

You should debug SQL by looking at the SQL query, not at the PHP code that produces the SQL query. If you echo $sql and look at it, you'll probably see any syntax errors much more easily.
You can also copy & paste that SQL and try to execute it in the MySQL command tool, and see what happens, whether it gives the result you want, you can profile it or use EXPLAIN, etc.
You're using mysql_real_escape_string() for integers, column names, and SQL keywords (ASC, DESC). That escape function is for escaping only string literals or date literals. It's useless for escaping unquoted integers, column names, SQL keywords, or any other SQL syntax.
For integers, use (int) to typecast inputs to an integer.
For column names or SQL keywords, use a whitelist map -- see example in my presentation http://www.slideshare.net/billkarwin/sql-injection-myths-and-fallacies
You're not testing for error statuses returned by any of your functions. Most functions in ext/mysql return false if some error occurs. You should check for that after every call to a mysql function, and report errors if they occur.
You're selecting a database using a constant name sample instead of a quoted string "sample". This might be intentional on your part, I'm just noting it.
Also, this is not related to your errors, but you should really upgrade to PHP 5. PHP 4 has been end-of-lifed for over two years now.
after looking at the code again and all the suggestions i think i should be using an AND clause and not WHERE. for example the code
$searchSql = ($qtype != '' && $query != '') ? "where ".$qtype." LIKE '%".$query."%' AND new = 1" : '';
this is the WHERE clause? which basically translates to:
$sql = "select *
from act
$searchSql
$sortSql
$limitSql"; <- original code
$sql = "select *
from act
WHERE company LIKE '%demo%' AND new = 1
$sortSql
$limitSql";<-updated code
am i on the right track?
