Assistance With Virtual Stock Market Plugin

[Serpius]

My Admin who is assisting me on my website does not have an account on MyBB-Plugins.com, but I do and I am using your Newpoints plugin.

So, he has this question regarding the plugin.

Oh yea... I should mention that he's using CoinMarketCap as the source to get the API from.
But, it can be from any API from any stock related website.

Thanks! 

I'm trying to get data from an API to show for the price of stocks.

I added this code into the virtualstock.php file

PHP Code:

function cryptoData()
{
   global $mybb, $cache, $db, $lang, $cryptoData;
     $url = "https://api.coinmarketcap.com/v1/ticker/";

 $json = file_get_contents($url);
 $data = json_decode($json, TRUE);

// Bitcoin price
 $btcprice = $data[0]["price_usd"];
 $usd_price = 10;
 $bitcoin_price = round( $usd_price / $btcprice , 8);
} 


So it now looks like this

PHP Code:

$categories[0] = $lang->virtualstock_select_cat;

function cryptoData()
{
   global $mybb, $cache, $db, $lang, $cryptoData;
     $url = "https://api.coinmarketcap.com/v1/ticker/";

 $json = file_get_contents($url);
 $data = json_decode($json, TRUE);

// Bitcoin price
 $btcprice = $data[0]["price_usd"];
 $usd_price = 10;
 $bitcoin_price = round( $usd_price / $btcprice , 8);
}

$query = $db->simple_select('virtualstock_categories', '*');
while ($cat = $db->fetch_array($query))
$categories[$cat['cid']] = $cat['name'];

$form = new Form("index.php?module=newpoints-virtualstock&action=do_addcompany", "post", "virtualstock");

$form_container = new FormContainer($lang->virtualstock_addcompany);
$form_container->output_row($lang->virtualstock_addedit_company_name."<em>*</em>", $lang->virtualstock_addedit_company_name_desc, $form->generate_text_box('name', '', array('id' => 'name')), 'name');
$form_container->output_row($lang->virtualstock_addedit_company_description, $lang->virtualstock_addedit_company_description_desc, $form->generate_text_box('description', '', array('id' => 'description')), 'description');
$form_container->output_row($lang->virtualstock_addedit_company_price, $lang->virtualstock_addedit_company_price_desc, $form->generate_select_box('price', $btcprice, array('id' => 'price')), 'price');
$form_container->output_row($lang->virtualstock_addedit_company_icon, $lang->virtualstock_addedit_company_icon_desc, $form->generate_text_box('icon', '', array('id' => 'icon')), 'icon');
$form_container->output_row($lang->virtualstock_addedit_company_disporder, $lang->virtualstock_addedit_company_disporder_desc, $form->generate_text_box('disporder', '0', array('id' => 'disporder')), 'disporder');
$form_container->output_row($lang->virtualstock_addedit_company_total, $lang->virtualstock_addedit_company_total_desc, $form->generate_text_box('total', 1000, array('id' => 'total')), 'total');
$form_container->output_row($lang->virtualstock_addedit_company_available, $lang->virtualstock_addedit_company_available_desc, $form->generate_text_box('available', 1000, array('id' => 'available')), 'total');
$form_container->output_row($lang->virtualstock_addedit_company_visible, $lang->virtualstock_addedit_company_visible_desc, $form->generate_yes_no_radio('visible', 1, true, "", ""), 'visible');
$form_container->output_row($lang->virtualstock_addedit_company_category."<em>*</em>", $lang->virtualstock_addedit_company_category_desc, $form->generate_select_box('cid', $categories, $cid, array('id' => 'cid')), 'cid'); 


My problem is I'm not sure how to get the data from the API to show in the price, so the line I need help with is this

PHP Code:

$form_container->output_row($lang->virtualstock_addedit_company_price, $lang->virtualstock_addedit_company_price_desc, $form->generate_select_box('price', $btcprice, array('id' => 'price')), 'price'); 


Not sure how I would add the data into that line for it to work correctly.
Any help would be awesome, thanks!
