我有一个CakePHP应用程序,它被用作我们公司日常活动的中心门户。这些包括各种预订系统和员工及其部门等信息。系统运行CakePHP 2.2
我目前正在实施的是一个招标人可以申请合同的系统。该合同有各种变化,这取决于在合同草案(截止日期)之前多长时间将合同草案移交给法人,以制定正式合同。然后系统“预订”#39;本合同成立几天的法人。那些日子里没有其他预订。
该系统运作良好,但它不会在周末拆分合同。它整天都在周末之前移动。让我们说,为了论证,我预订了一份合同草案,将于6月18日完成。系统确定总合同时间为3天。这意味着合同应该在一个周末结束,它应该阻止6月13日,14日和17日(不是18日,因为我需要在那时完成完成的文档)。但是,该系统将于6月12日至14日停止。
很抱歉长篇大论,但我宁愿让你知道完整的故事,而不仅仅是点点滴滴。这是我的系统代码:
$tenderDocument = $this->TenderDocument->read(null,$id);
$deadline = $tenderDocument['TenderDocument']['required_date'];
$deadline = $start = date('Y-m-d',strtotime('-1 day',strtotime($deadline)));
$start = date('Y-m-d',strtotime('-' . $tenderDocument['ContractForm']['time'],strtotime($deadline)));
$dates[] = $current = $start;
while($current < $deadline){
$current = date('Y-m-d',strtotime('+1 day',strtotime($current)));
$dates[] = $current;
}
$is_available = array();
$is_available = $this->TenderDocument->find('first',
array(
'conditions' => array(
'(TenderDocument.start_date >= "' . $start . '" AND
TenderDocument.start_date < "' . $deadline . '" OR
TenderDocument.start_date <= "' . $deadline . '" AND
TenderDocument.required_date > "' . $deadline . '") AND
TenderDocument.id != ' . $id
)
)
);
$is_weekend = false;
foreach($dates as $date) {
if(date('l',strtotime($date)) == 'Sunday' || date('l',strtotime($date)) == 'Saturday') {
$is_weekend = true;
}
}
while(!empty($is_available) || $is_weekend) {
$is_weekend = false;
$dates = array();
$deadline = date('Y-m-d',strtotime('-1 day',strtotime($deadline)));
$start = date('Y-m-d',strtotime('-1 day',strtotime($start)));
$dates[] = $current = $start;
while($current < $deadline){
$current = date('Y-m-d',strtotime('+1 day',strtotime($current)));
$dates[] = $current;
}
foreach($dates as $date) {
if(date('l',strtotime($date)) == 'Sunday' || date('l',strtotime($date)) == 'Saturday') {
$is_weekend = true;
}
}
$is_available = $this->TenderDocument->find('first',
array(
'conditions' => array(
'(TenderDocument.start_date >= "' . $start . '" AND
TenderDocument.start_date < "' . $deadline . '" OR
TenderDocument.start_date <= "' . $deadline . '" AND
TenderDocument.required_date > "' . $deadline . '") AND
TenderDocument.id != ' . $id
)
)
);
}
在一个不相关的说明中,有什么方法可以简化/最小化这段代码吗?

我希望我能正确理解您的问题,您需要计算合同的结束日期,并给出应该运行的天数,而不要将周末计算为工作日。
PHP的DateTime类可以大大简化您的代码。我认为这个功能可以帮到你: -
/**
* Given the start date of a contract will return the end date, skipping weekends
*
* @param String $starDate format 'Y-m-d'
* @param Int $numberOfDays Number of working days
* @return Array of date strings
*/
function getDeadline($starDate, $numberOfDays)
{
$start = \DateTime::createFromFormat('Y-m-d', $starDate);
$interval = new DateInterval('P1D');
$result = array();
$i = 0;
while($i < $numberOfDays){
if((int)$start->format('N') < 6){
$result[] = $start->format('Y-m-d');
$i++;
}
$start->add($interval);
}
return $result;
}
$start = '2013-6-12';
var_dump(getDeadline($start, 4));
输出: -
array (size=4)
0 => string '2013-06-12' (length=10)
1 => string '2013-06-13' (length=10)
2 => string '2013-06-14' (length=10)
3 => string '2013-06-17' (length=10)

我以完全不同的方式做到了。
我按日期收到了要求,创建了2个月的日期范围,然后从阵列中删除了已经预订了几天的所有星期六和星期日PLUS。然后我反向排序,并选择第一个所需的天数。
function _createDateRangeArray($strDateFrom,$strDateTo) {
$aryRange=array();
$iDateFrom=mktime(1,0,0,substr($strDateFrom,5,2), substr($strDateFrom,8,2),substr($strDateFrom,0,4));
$iDateTo=mktime(1,0,0,substr($strDateTo,5,2), substr($strDateTo,8,2),substr($strDateTo,0,4));
if ($iDateTo>=$iDateFrom)
{
array_push($aryRange,date('Y-m-d',$iDateFrom)); // first entry
while ($iDateFrom<$iDateTo)
{
$iDateFrom+=86400; // add 24 hours
array_push($aryRange,date('Y-m-d',$iDateFrom));
}
}
return $aryRange;
}
public function confirm($id = null) {
if($this->request->is('post')) {
$this->TenderDocument->create();
$data = array(
'TenderDocument' => array(
'id' => $id,
'book_dates' => implode(',',$this->request->data['TenderDocument']['book_days'])
)
);
if($this->TenderDocument->save($data)) {
$this->_sendTenderDocument($id);
$this->Session->setFlash('Tender document request saved.','default',array('class'=>'notification'));
$this->redirect(array('action'=>'add'));
} else {
$this->Session->setFlash('There was an error saving your deadline. Please retry.','default',array('class'=>'error'));
}
}
$this->TenderDocument->id = $id;
if (!$this->TenderDocument->exists()) {
throw new NotFoundException(__('Invalid tender document'));
}
$tenderDocument = $this->TenderDocument->read(null,$id);
$deadline = $tenderDocument['TenderDocument']['required_date']; // Deadline date as entered on form
$deadline = $start = date('Y-m-d',strtotime('-1 day',strtotime($deadline))); // adjusted deadline
$start = date('Y-m-d',strtotime('-3 months',strtotime($deadline))); // adjusted start
$period = $this->_createDateRangeArray($start,$deadline);
$TenderDocuments = $this->TenderDocument->find('list',
array(
'fields' => array('TenderDocument.book_dates')
)
);
$dates = array();
foreach($TenderDocuments as $TenderDocument) {
$doc_dates = explode(',',$TenderDocument);
foreach($doc_dates as $doc_date) {
$dates[] = $doc_date;
}
}
foreach($period as $key=>$value) {
if(date('l',strtotime($value)) == 'Saturday' || date('l',strtotime($value)) == 'Sunday' || in_array($value,$dates)) {
unset($period[$key]);
}
}
rsort($period);
for($k = 0; $k <= $tenderDocument['ContractForm']['time']; $k++) {
$book_days[] = $period[$k];
}
$this->set('TenderDocument',$this->TenderDocument->read(null,$id));
$this->set('book_days',$book_days);
}
