Question

我想在php中创建一组规则我有一个包含2个选择字段的表单（值为1＆gt; 5

Cookies are:
$Field1 = intval($_POST["Field1"]);
$Field2= intval($_POST["Field2"]);

我想在下面创建一个规则

Field1 has 1 selected and Field2 has 2 selected

if ( count($Field1) = 1) and ( count($Field2) = 2)
    array_push($box,array("paxType" => "Cake"), array("paxType" => "Cake"));

或

Field1 has 2 selected and Field2 has 3 selected

if ( count($Field1) = 2) and ( count($Field2) = 4)
    array_push($box,array("paxType" => "Cake"), array("paxType" => "Cake"));
    array_push($box,array("paxType" => "Cake"), array("paxType" => "Cake"));

或

Field1 has 2 selected and Field2 has 3 selected

if ( count($Field1) = 2) and ( count($Field2) = 3)
    array_push($box,array("paxType" => "Cake"), array("paxType" => "Cake"));
    array_push($box,array("paxType" => "Cake"));

等等。

这是可能的吗？

上面的代码不正确，但我已输入它以显示我需要的内容。

Answer 1

您期望得到什么结果？

如果你做这样的事情：

$box = array();
// Field1 has 2 selected and Field2 has 3 selected
if ($Field1 == 2) and ($Field2 == 4) {
    array_push($box,array("paxType" => "Cake"), array("paxType" => "Cake"));
    array_push($box,array("paxType" => "Cake"), array("paxType" => "Cake"));
}
print_r($box);

唯一的结果是一个数组，其中包含您在$ Field2中提交的项目数。

//output:
Array
(
    [0] => Array([paxType] => Cake),
    [1] => Array([paxType] => Cake),
    [2] => Array([paxType] => Cake),
    [3] => Array([paxType] => Cake)
)

Answer 2

由于您最近的声明：

结果应该是：一个awoat有3个蛋糕，一个有2个蛋糕。一个阵列可以填充3个蛋糕naxinun。

以下代码将按预期执行：

<?php

class boxes
{
    private $_boxes = array();
    public $maxCake = 3; // default .. 3

    public function addBox()
    {
        $this->_boxes[] = array();
    }

    public function getBoxes()
    {
        return $this->_boxes;
    }

    public function addCake($boxNum = 0, $cake = array('paxType' => 'Cake'))
    {
        if (empty($this->_boxes)) {
            $this->addBox();
        }

        if (empty($this->_boxes[$boxNum])) {
            $this->_boxes[$boxNum] = array();
        }

        // if box is full with cakes (maxCake) create a new one
        if (count($this->_boxes[$boxNum]) == $this->maxCake) {
            $oldBoxNum = $boxNum;
            // searching for a box with enough space for another cake
            foreach ($this->_boxes as $key => $box) {
                if (count($box) != $this->maxCake) {
                    $boxNum = $key;
                    break;
                }
            }
            // if we can't found one we add a new box
            if ($oldBoxNum == $boxNum) {
                $this->addBox();
                $boxNum++;
            }
        }

        $this->_boxes[$boxNum][] = $cake; 
    }
}

$Field1 = 1; // boxes
$Field2 = 5; // cakes

$boxes = new boxes();
$boxes->maxCake = 3; // if there are more than 3 cakes in a box, a new box will be created

// create number of boxes given with field1
for ($x = 0; $x < $Field1; $x++) {
    $boxes->addBox();
}

// add cakes given with field2
$y = 0;
for ($x = 0; $x < $Field2; $x++) {
    $boxes->addCake($y);
    $y++;
    if ($Field1 == $y) {
        $y = 0;
    }
}

$result = $boxes->getBoxes();
for ($x = 0; $x < count($result); $x++) {
    echo 'Box' . ($x + 1) . ':';
    echo "<br>";
    print_r($result[$x]);
    echo "<br>";
}

输出：

Box1:
Array (
    [0] => Array( [paxType] => Cake )
    [1] => Array( [paxType] => Cake )
    [2] => Array( [paxType] => Cake )   
)                                                      

Box2:  
Array (                                                      
    [0] => Array( [paxType] => Cake )
    [1] => Array( [paxType] => Cake )
)

如果计算两个或更多变量，则创建一组规则。来自HTML格式
