cakephp分页条件

Question

我已经定义了条件变量值。我需要写这个格式我怎么写这个。

$this->Paginator->settings = array('conditions' => array(
    if(!empty($this->request->data['filter']['delivery']))
    {
    'Gig.delivery <=' => $this->request->data['filter']['delivery'],
    }
    if(!empty($this->request->data['filter']['delivering']))
    {
    "Gig.bangsalsodelivering IN ({$csv_deliveringfilters})",
    }
    if(!empty($this->request->data['filter']['servicetype']))
    {
    "Gig.bangsservicetype IN ({$csv_bangsservicetypesfilters})",
    }
    if(!empty($this->request->data['filter']['style']))
    {
    "Gig.bangsstyles IN ({$csv_stylefilters})",
    }
    if(!empty($this->request->data['filter']['fileformate']))
    {
    "Gig.bangsfileformates IN ({$csv_fileformatefilters})",
    }
));
$agetGigsItem = $this->Paginator->paginate('Gig');

Answer 1

条件通常是一个数组

条件通常作为数组处理，不作为字符串处理。比如这个：

$this->Paginator->settings = [
    'conditions' => ['Gig.field' => 'is this value']
];

$agetGigsItem = $this->Paginator->paginate('Gig');

将应用此 sql 条件：

WHERE Gig.field = "is this value"

使用字符串连接构建条件是一个坏主意。除了更麻烦之外，这意味着您需要自己处理用户输入的转义。

工作解决方案

鉴于问题中的代码，这将执行所要求的操作：

$conditions = [];
$filter = $this->request->data['filter'];

if(!empty($filter['delivery'])) {
    $conditions['Gig.delivery <='] = $filter['delivery'];
}

if(!empty($filter['delivering'])) {
    $conditions['Gig.bangsalsodelivering'] = explode(',', $filter['delivering']);
}

if(!empty($filter['servicetype'])) {
    $conditions['Gig.bangsservicetype'] = explode(',', $filter['servicetype']);
}

if(!empty($filter['style'])) {
    $conditions['Gig.bangsstyles'] = explode(',', $filter['style']);
}

if(!empty($filter['fileformate'])) {
    $conditions['Gig.bangsfileformates'] = explode(',', $filter['fileformate']);
}

$this->Paginator->settings['conditions'] = $conditions;
$agetGigsItem = $this->Paginator->paginate('Gig');

请注意，数组值会自动转换为IN () 条件子句，如果不等于 - 则比较在数组键中。
