好吧，让我从头开始，我是一个新手，正在研究一个用 cakephp 1.2 编码并试图让它工作的发票示例，但我使用的是 Cakephp 2.1 和 php 5.?? 这意味着一些代码已从原始代码更改，我正在尝试找出它们，这个错误已经查看了 3 天但没有得到任何地方，这就是我发送求救信号的原因:)。
私有方法
function __lists ()
{
$users = $this->Invoice->User->find('list', array('fields'=> array('User.id', 'User.username')));
$statuses = $this->Invoice->Status->find('list');
$clients = $this->Invoice->Client->find('list');
/*$units = $this->Invoice->Item->Unit->find('list');*/
$this->set('units', $this->Invoice->Item->Unit->find('list'));
$categories = $this->Invoice->Category->find('list');
$this->set(compact('users', 'statuses', 'clients', 'categories','units'));
}
# Tallys up invoice and alters $this->data
# adding total, subTotal and taxTotal
function __tallyUpInvoice()
{
$this->__itemTotals();
$subTotal = $this->__subtotal($this->data['Item']);
$taxTotal = $this->__tax($subTotal, $this->data['Invoice']['taxRate']);
$this->request->data['Invoice']['total'] = $subTotal + $taxTotal;
$this->request->data['Invoice']['subTotal'] = $subTotal;
$this->request->data['Invoice']['taxTotal'] = $taxTotal;
return true;
}
# returns line item qty times price
function __lineItemTotal($qty, $price)
{
$arrayjoin = array_merge((array)$qty, (array)$price);

print_r($arrayjoin);
/*return array($qty) * array($price);
/*return array_product($qty) + array_product($price); */
}
# Alters $this->data['Item']['total'] with total of line item.
function __itemTotals()
{
$itemsCount = isset($this->data['Item']) ? count($this->data['Item']) : 0;
for ($i=0; $i < $itemsCount; $i++)
{
$this->request->data['Item'][$i]['total'] = $this->__lineItemTotal($this->request->data['Item'][$i]['qty'], $this->request->data['Item'][$i]['price']);
// collect unit name from unit model
$unit = $this->Invoice->Item->Unit->find('first', array('conditions' => array('Unit.id =' => $this->request->data['Item'][$i]['unit_id']), 'fields' => array('Unit.name')));
$this->request->data['Item'][$i]['name'] = $unit['Unit']['name'];
}
}
# returns sub total price
function __subTotal($items)
{
$price = 0.0;
foreach ($items as $item)
{
$price += $this->__lineItemTotal($item['qty'], $item['price']);
}
return $price;
}
# returns total tax amount
function __tax($subTotal, $taxRate)
{
$taxTotal = round(($taxRate * 0.01 * $subTotal) * 1000) / 1000;
return round($taxTotal * 100) / 100;
}
# attaches Invoice.id to $this->data['Item']
function __attachInvoiceIdToItems($id)
{
$itemsCount = isset($this->request->data['Item']) ? count($this->request- >data['Item']) : 0;
for ($i=0; $i < $itemsCount; $i++)
{
$this->request->data['Item'][$i]['invoice_id'] = $id;
}
}
上面的代码片段与我正在处理的代码部分有关，从头开始。 这是原始代码
# returns line item qty times price
function __lineItemTotal($qty, $price)
{
return $qty * $price;
}
阅读此处后，我收到一个错误操作数错误，这是我试图用一个字符串进行乘法和数组运算，或者这就是我的想法，所以我将其更改为下面的函数
# returns line item qty times price
function __lineItemTotal($qty, $price)
{
$arrayjoin = array_merge((array)$qty, (array)$price);
return array_product($arrayjoin);
settype($arrayjoin, "integer");
print_r($arrayjoin);
}
Now I am getting another error when there is a decimal number selected as a price, below is the notice code and context.

看了几个星期后，我发现保存它 mysql 正在尝试保存一个数组，那个设置在哪里？
Code:
$valueInsert = array(
(int) 0 => '1',
(int) 1 => array(
(int) 0 => '55.00'
),
(int) 2 => array(
(int) 0 => '' testing =\"testing \"''
),
(int) 3 => array(
(int) 0 => '10.01'
),
(int) 4 => '550.55',
(int) 5 => ''Service'',
(int) 6 => '49'
)
谢谢大家希望可以解决这个问题。
干杯
