Question

我在CakePHP项目上设置了一个简单的搜索引擎，如下所示：

<?php 
    echo $this->Form->create("Post", array(
        "action" => "search", 
        "id" => "searchForm"
    ));
    echo $this->Form->input("keyword", array(
        "label" => "",
        "type" => "search",
        "placeholder" => "Recherche..."
    ));
    echo $this->Form->end(); 
?>

这是控制器：

function search() {
    $keyword = $this->request->data;
    $keyword = $keyword["Post"]["keyword"];
    $cond = array("OR" => array(
        "Post.title LIKE '%$keyword%'",
        "Post.description LIKE '%$keyword%'"
    ));
    $posts = $this->Post->find("all", array("conditions" => $cond));
    $this->set(compact("posts", "keyword"));
}

它很棒。唯一的问题是我想要对结果进行分页。我只想补充一下：

$posts = $this->paginate();

这就是问题所在。当我添加它时，CakePHP会给我所有帖子，而不仅仅是那些与关键字匹配的帖子。

所以，如果你有一个解决方案，那就太好了：）

Answer 1

根据CakePHP的书，你应该可以做到

$this->paginate('Post', array(
    'OR' => array(
        'Post.title LIKE' => "%$keyword%",
        'Post.description LIKE' => "%$keyword%"
    )

));

或者你可以这样做（来自cakephp网站）。

public function list_recipes() {
    $this->paginate = array(
        'conditions' => array('Recipe.title LIKE' => 'a%'),
        'limit' => 10
    );
    $data = $this->paginate('Recipe');
    $this->set(compact('data'));
);

Paginate对我认为的数据进行自己的查询。您之前调用的find对paginate无效。

试试这个：

$this->paginate = array( 'conditions' => $cond, ));

Answer 3

您可以使用Session存储条件
第一，当您提交表格时，您将条件存储到会话中然后（分页）你可以从Session

中读取条件

example i want to search the products:
Products/search.ctp
<?php
    echo $this->Form->create('Product');
    echo $this->Form->input('keyword');
    echo $this->Form->end(__('Search'));
?>
ProductsController.php
<?php 
class ProductsController extends AppController{

public function search() {
        if ($this->request->is('post')) {
            $keyword = $this->request->data['Product']['keyword'];
            $this->paginate = array(
                'fields' => array('Product.name', 'Product.price', 'Product.created'),
                'order' => array('Product.created' => 'DESC', 'Product.price' => 'DESC'),
                'limit' => 30,
                'conditions' => array('Product.name LIKE' => '%' . $keyword . '%')
            );
            // store array $this->paginate into Session
            $this->Session->write('paginate', $this->paginate);
        }
        $this->paginate = $this->Session->read('paginate');
        $this->set('products', $this->paginate('Product'));
    }
}
