We Keep Coding

I need to choose more values from some tasks that belong to same project

My question is: Is there any other method to select the values I need from all the tasks that belongs to same project and sum them? Other method that I tried in the down description?
Description:
I have an app where I can create a Project and, inside the Project, I can create Tasks. For every Task, I can add a percent and calculate a price (example picture 1).
Then I have a report page where I want to calculate all the prices from all of the Tasks of same project (example picture 2).
My problem is when I want to select all the prices from all the tasks that belongs to same projects and sum them in the table "price" of report page.
For the moment I tried a method with the code I put down, and it's not working as I need, because it take the correct value from the first task of the project but dont take corect value from the ohther tasks from the same project
picture 1
picture 2 (but here the problem is that just the first array is corrent the other are not)
code I use ( I commented in the code with "the code that doesnt work" the part that make the sum) :

How to display text when RSS feed is empty

I have been struggling with this for a while now, I got some help from a similar question but I can't seem to make it work in my example.
I have an RSS feed on my website and what I am trying to do is display a message saying "No Warnings" when the RSS feed is blank/empty. If there is something in the RSS feed then I just want to show that.
For the life of me I can't get this to work! I can't get it to recognize the feed is blank...is this possible??
Here is my code,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" dir="ltr" lang="en">

$rss = RSS_Display($url, 15, false, false);
if ($rss == '')
{
// nothing shown, do whatever you want
echo 'No Current Warnings';
}
else
{
// something to display
echo $rss123;
}
?>
</fieldset>
</body>

If it helps RSS_Display is from the rsslib.php file, which I have provided below,

Any help would be much appreciated.
Many thanks.

If you look at the rsslib code, you see that if the rss has no articles, the returned string will be \n.
The test to check if the RSS is empty should be if ($rss == "\n")
In addition to this, rsslib seems to be an old code (2010) and it is not object oriented (this is a problem because there are global vars defined outside the functions which can be in conflict with your code.
Moreover, this class does all the formatting of the RSS so if you want to change it, you will need to change the rsslib code.
You should consider using an other class like this one : https://github.com/dg/rss-php which is object oriented and easy to use.

Why does php code not recognize a database update?

I have some php and html code and a small bit of JavaScript. Its a like system. Click the like button or dislike button and when you exit/leave the page the JavaScript and ajax runs a php file to update the database with the changes.(+1 to likes or +1 to dislikes or -1 to dislikes etc.) There is one problem. I click like/dislike and then i leave/ refresh page and the likes have not changed in value. If i dont click anything, which means im not updating the database and i refresh/leave a second time the likes are updated on the screen to what they should be. The database gets updated when its suppose to, its the code that dosnt use the new value for whatever reason. Here's my code:

What is wrong with the code that makes it not update the amount of likes on the first refresh but does update on the second refresh?

Error In Javascript code with php

I wanna make statistics in my website for the last 3 years
I want to show result like this
2016 : 159
2015 : 132
2014 : 200
I try my code (this's)
$date2 = date('Y');
$n = $date2;
for($i=$n-2;$i<=$n;$i++) {
$sql = "SELECT sum(count) AS value_sum FROM statistics where YEAR(st_date) = $i ";
$sql_sel = mysqli_query($conn,$sql);
echo '
<script>
var pieData = [
';
while($rows = mysqli_fetch_assoc($sql_sel)) {
if($i == $n-2) {
echo '{
value: '.$rows['value_sum'].',
color:"#337AB7"
},';
}
else if($i == $n-1) {
echo '{
value: '.$rows['value_sum'].',

},';
}
else if($i == $n) {

}
echo'];
new Chart(document.getElementById("pie").getContext("2d")).Pie(pieData);
</script>';
}}
?>
but this code give me just 1 one row like this
2016 : 159
I wanna see all result, any help ?

You're creating 3 charts within your for loop. If you allow php to encode the data for you, you can echo the script outside of the PHP like so:
$date2 = date('Y');
$n = $date2;
$data = array();
for($i=$n-2;$i<=$n;$i++) {
$sql = "SELECT sum(count) AS value_sum FROM statistics where YEAR(st_date) = $i ";

var pieData = <?php json_encode($data) ?>;
new Chart(document.getElementById("pie").getContext("2d")).Pie(pieData);

This should help you out:
<?php
// Store the array for the pie data within PHP at first
$js_pie_data = [];
// Define colors
$colors = [
date('Y') => '8BC34A', // current year
(date('Y') - 1) => 'FC8213', // last year
(date('Y') - 2) => '337AB7' // 2 years ago
];
$sql = "SELECT
YEAR(st_date) as `year`, -- get year from DB, makes life simpler :)
sum(count) AS value_sum
FROM
statistics
WHERE
YEAR(st_date) >= (YEAR(CURDATE())-2) -- get all records from 2 years ago to today
GROUP BY
YEAR(st_date) -- group by year so that our sum() above will work";
$sql_sel = mysqli_query($conn,$sql);
while($rows = mysqli_fetch_assoc($sql_sel))
{
// keep adding entries to the pie data
$js_pie_data[] = [
'value' => $rows['value_sum'],
'color' => '#'.$colors[$rows['year']] // based on year from DB, pick a color
];
}
echo '<script>
var pieData = '.json_encode($js_pie_data).'; // this will output a properly formatted JS array which will be understood by JS with no problem
new Chart(document.getElementById("pie").getContext("2d")).Pie(pieData);
</script>';

1)You can create array in php side.
2)Then convert it as json string.
3)Define javascript variable with that json string
4)Convert it as object with JSON.parse
5)Insert it in option
<?php
$db = Array("1","2","3");
$out = Array();
$x = 0;
foreach($db as $vals){
if($x == 1){
$out[] = Array("value"=>$vals,"color"=>"#bfbfbf");
}
if($x == 2){
$out[] = Array("value"=>$vals,"color"=>"#00ffff");
}
if($x == 3){
$out[] = Array("value"=>$vals,"color"=>"#fff00");
}
if($x == 3){$x = 0;}
$x++;
}
echo "
<script language='javascript'>
var stat_str = '".json_encode($out)."';
var stat_obj = JSON.parse(stat_str);
// then you can insert stat_obj if you need object into stats
</script>";
?>

Alert box is not showing in codeigniter models

in the model alert is not working. if condition is working,the only problem with the alert box, its not showing the dialog box.Please help..
public function setJumlahPenumpang ($idJadwal,$idPemesanan,$jml,$booked,$selected){
$data1 = $this->db->query('select p.jumlah_kursi, j.jumlah_penumpang, p.harga from tb_po p JOIN tb_jadwal j ON j.id_po = p.id_bus WHERE j.id_jadwal ='. $idJadwal);
foreach ($data1->result_array() as $dataa1) {
$tersedia = $dataa1['jumlah_kursi'] - $dataa1['jumlah_penumpang'];
if($tersedia < $jml){
?>
<script type="text/javascript">
document.location = '<?php echo base_url(); ?>proses/cekKode1/<?php echo $idPemesanan ?>';
alert("Tidak ada Bus Beroperasi");
</script>
<?php
}else{
$data3 = $dataa1['harga'] * $jml;
$this->db->query('update tb_pemesanan set harga = '.$data3.' where id_pemesanan = '.$idPemesanan);
$data = $this->db->query('select jumlah_penumpang from tb_jadwal where id_jadwal ='. $idJadwal);
$this->db->query("update tb_jadwal set booked = '".$booked."' where id_jadwal = ".$idJadwal);
$this->db->query("update tb_pemesanan set kursi = '".$selected."' where id_pemesanan = ".$idPemesanan);
foreach ($data->result_array() as $dataa) {
$data2 = $dataa['jumlah_penumpang'] + $jml;
$this->db->query('update tb_jadwal set jumlah_penumpang = '.$data2.' where id_jadwal = '.$idJadwal);
}
}
}
}

Try Echo Before Script Tag I hope So it 'll work....
if($package_id == NULL) {
echo '<script type="text/javascript">
window.location.href = "'.base_url().'"
</script>';
return;
die();
}
