PHP Can you help me confirm the purpose of this code?

[chrisj]

In this web script, that I'm trying to modify, it has this section of php code:

$withdrawal_history = "";
if ($pt->setting_page == 'withdrawals') {
    $user_withdrawals  = $db->where('user_id',$pt->user->id)->get(T_WITHDRAWAL_REQUESTS);
    foreach ($user_withdrawals as $withdrawal) {
        $pt->withdrawal_stat = $withdrawal->status;
        $withdrawal_history .= PT_LoadPage("settings/includes/withdrawals-list",array(
            'W_ID' => $withdrawal->id,
            'W_REQUESTED' => date('Y-F-d',$withdrawal->requested),
            'W_AMOUNT' => number_format($withdrawal->amount, 2),
            'W_CURRENCY' => $withdrawal->currency,
        ));
    }
}

I know that T_WITHDRAWAL_REQUESTS is the withdrawal_requests db table. So, does this chunk of code appear to take the withdrawal request amount from the table and load it into the page that displays the withdrawal requests history?

If not, what is this code doing? If so, is it possible to modify this code here to change the amount displayed? Such as displaying half of the amount (that is populated in the withdrawal history table's amount column) into the page that displays the withdrawal requests history ?

Hey there,

I'm in no way an expert in PHP but from what I can see in the code, I think you are spot on. @Ghost would this be right?

$withdrawal_history = "";
This is just setting the history string to be blank, nothing.

if ($pt->setting_page == 'withdrawals') {
If we're on the page for withdrawals... let's access withdrawals:

$user_withdrawals = $db->where('user_id',$pt->user->id)->get(T_WITHDRAWAL_REQUESTS);
The user withdrawals array will hold data from the database table 'T_WITHDRAWAL_REQUESTS' which is a defined constant (so whatever that is), where the column user_id is the target user's id

foreach ($user_withdrawals as $withdrawal) {
Loop through each found result from the query above.

$pt->withdrawal_stat = $withdrawal->status; $withdrawal_history .= PT_LoadPage("settings/includes/withdrawals-list",array( 'W_ID' => $withdrawal->id, 'W_REQUESTED' => date('Y-F-d',$withdrawal->requested), 'W_AMOUNT' => number_format($withdrawal->amount, 2), 'W_CURRENCY' => $withdrawal->currency, ));
This code is pulling a view (loadpage) that is a withdrawals list, and it's inserting data from the current row (in the foreach loop) of data it found. So it's probably constructing a <tr> HTML row or something.

'W_AMOUNT' => number_format($withdrawal->amount / 2, 2),
Pretty sure you can just do the / 2 part after $withdrawal->amount and it's good to go if you want to show half amounts!
