How to generate a grid(Table) with a foreach - foreach

Question

My problem is simple, but I'm beginning with cakephp. I'll explain my problem:
I have 2 tables:
Table: Expenditures
Columns:
sub_category_id
account_id
date
ammount
created
modified
description
Table: BudgetRecords
Columns:
budget_id
ammount
sub_category_id
created
modified
I have a 'home-work' to do, and my teacher wants me to do a report. This report will generate a table, and will show an balance (Expenditures.ammount - BudgetRecords.ammount), and each month (BudgetRecords.created, or Expenditures.date, whatever).
Here's my question: I'm trying to do a foreach, passing for each year (if exists), if a year exists, then execute a query for each month. But, how I do that with CakePHP? I've tried to do this only inside the Controller, and it runs fine. But returns me only the last month of the last year. Then, I've tried a different approach.
Inside the View, execute the query and search if exists the year. If exists, then search for this month. Then gives me back the result.
That's what I did:
Inside the View:
<table align="center" border="2" rules="All">
<tr>
<td>Valor:</td>
<td>Data:</td>
</tr>
<?php
for ($month = 1; $month <= 12; $month++) {
if (strlen($month) == 1)
$month = '0' . $month;
foreach ($Expenditure->SaldoMes($month) as $result) {
echo "<tr>";
echo "<td> R$:" . $result[0] . "</td>";
echo "<td> " . $result[1] . "</td>";
echo "</tr>";
}
}
?>
</table>
Inside the Controller:
public function SaldoMes($month = null) {
$month = 0;
for ($month = 1; $month <= 12; $month++) {
if (strlen($month) == 1)
$month = '0' . $month;
$query = "SELECT (SUM(ex.ammount) - SUM(br.ammount)) as total , br.created as data
FROM budget_Records br, expenditure ex
where SUBSTRING(br.created, 6, 2) = '" . $month .
"' and SUBSTRING(br.created, 6, 2) = SUBSTRING(ex.created, 6, 2)";
$this->set('Expenditure', $this->Expenditure->query($query));
foreach ($this->Expenditure->query($query) as $records) {
$this->set(('Total'), $records[0]['total']);
$this->set(('Data'), $records['br']['data']);
}
}
}
I hope I've explained my problem well enough for someone to show me a solution.

Answer 1

I think this will help
http://book.cakephp.org/2.0/en/controllers.html
This part is what you are looking for I think. Taken from that website.
<?php
# /app/Controller/RecipesController.php
class RecipesController extends AppController {
public function view($id) {
//action logic goes here..
}
public function share($customer_id, $recipe_id) {
//action logic goes here..
}
public function search($query) {
//action logic goes here..
}
}
"The view files for these actions would be app/View/Recipes/view.ctp, app/View/Recipes/share.ctp, and app/View/Recipes/search.ctp. The conventional view file name is the lower cased and underscored version of the action name."
So if you wanna just use another method like SaldoMes() then just call it in the view method.

#earlonrails, solved:
public function SaldoMes() {
$result = array();
for ($month = 1; $month <= 12; $month++) {
if (strlen($month) == 1)
$month = '0' . $month;
$query = "SELECT (SUM(ex.ammount) - SUM(br.ammount)) as total , br.created as data
FROM budget_Records br, expenditure ex
where SUBSTRING(br.created, 6, 2) = '" . $month .
"' and SUBSTRING(br.created, 6, 2) = SUBSTRING(ex.created, 6, 2)";
$this->set('Expenditure', $this->Expenditure->query($query));
foreach ($this->Expenditure->query($query) as $records) {
$result[$month][0] = $records[0]['total'];
$result[$month][1] = $records['br']['data'];
}
}
return $this->set('result', $result);
}
Using the $result array, now i can get my values.
Thanks for teh help.
