Hi,
I don't know if this is the right place to ask Drupal related PHP
questions, so please bear with me. I've got two arrays and a form like
below:
/*
* This function stuffs currency codes into an array,
* check the TCMB XML file for matching records, and
* displays the relevant code's exchange rates in a table
*/
function tcmb_get_currencies() {
$tcmb_cur_codes = array(
1 => 'USD',
2 => 'CAD',
3 => 'XDR',
4 => 'DKK',
5 => 'SEK',
6 => 'CHF',
7 => 'NOK',
8 => 'JPY',
9 => 'SAR',
10 => 'KWD',
11 => 'AUD',
12 => 'EUR',
13 => 'GBP',
14 => 'RUB',
15 => 'RON',
16 => 'IRR',
17 => 'BGN',
18 => 'DEM',
19 => 'BEF',
20 => 'LUF',
21 => 'ESP',
22 => 'FRF',
23 => 'IEP',
24 => 'ITL',
25 => 'NLG',
26 => 'ATS',
27 => 'PTE',
28 => 'FIM',
29 => 'GRD'
);
$tcmbXML = new DomDocument();
$tcmbXML->load('http://www.tcmb.gov.tr/kurlar/today.xml');
$currency = array();
$rows = array();
$result = variable_get('tcmb_currency', $currency);
// Let's find out if $result is a variable
if (!is_array($result)) {
watchdog('Error: The tcmb_currency variable was not an array.');
drupal_set_message(t('Error: The tcmb_currency variable was not an
array.'));
return;
}
foreach ($result as $tcmb) {
$tcmb_cur = $tcmb['currency'];
$currency[] = $tcmb_cur;
$curcode = $tcmb_cur_codes[$tcmb_currency];
$buy =
$tcmbXML->getElementsByTagName('ForexBuying')->item($tcmb_cur)->nodeValue;
$sell =
$tcmbXML->getElementsByTagName('ForexSelling')->item($tcmb_cur)->nodeValue;
$rows[] = array($curcode, $buy, $sell);
}
$header = array('', t('BUYING'), t('SELLING'));
$output = theme('table', $header, $rows);
return $output;
}
...
...
...
/*
* This function generates the form and allows the admin to set the
currency code(s).
*/
function tcmb_settings_form() {
$form = array();
$form['tcmb_currency'] = array(
'#title' => t('Currency code'),
'#default_value' => variable_get('tcmb_currency', array()),
'#type' => 'checkboxes',
'#options' => array(1 => t('American Dollar'), 2 => t('Canadian
Dollar'), 3 => t('Special D. Rights'), 4 => t('Danish Krone'), 5 =>
t('Swedish Krona'), 6 => t('Swiss Franc'), 7 => t('Norwegian Krone'), 8
=> t('Japanese Yen'), 9 => t('Saudi Arabian Riyal'), 10 => t('Kuwaiti
Dinar'), 11 => t('Australian Dollar'), 12 => t('Euro'), 13 => t('Great
Britain Pounds'), 14 => t('Russian Ruble'), 15 => t('Romanian Leu'), 16
=> t('Iranian Riyals'), 17 => t('Bulgarian Lev'), 18 => t('German
Marc'), 19 => t('Belgian Franc'), 20 => t('Luxembourgian Franc'), 21 =>
t('Spanish Peseta'), 22 => t('French Franc'), 23 => t('Irish Pound'), 24
=> t('Italian Lira'), 25 => t('Dutch Guilder'), 26 => t('Austrian
Schilling'), 27 => t('Portuguese Escudo'), 28 => t('Finnish Mark'), 29
=> t('Greek Drachma')),
);
return system_settings_form($form);
};
As you can see, I'm trying to return a table with the relevant rates in
it. However, whatever I check, I get USD rates, and also it lists all 29
values (all USD by the way) even if there are only 2. What do I need to do?
Regards,
