Php 如何一次在多个字段中搜索多个单词？

我正在编写一个搜索模块。我不知道我是否在一个好的方式，但我现在听起来不错，除了一点

使用下面的代码，我只能搜索一个单词

<?php
class SearchesController extends AppController{

    function index(){

        if($this->request->is('put') || $this->request->is('post') ){
            // Save the send data
            $search = $this->request->data['Search']['key']; 

            //$nbWords = str_word_count($search);
            /*
            THIS DOES NOT WORKS
            if($nbWords > 1){
                $searchTerms = explode(' ', $search);

                $searchTermBits = array();
                foreach ($searchTerms as $term) {
                    $term = trim($term);
                    if (!empty($term)) {
                        $searchTermBits[] = "Page.name LIKE '%$term%' AND Page.content LIKE '%$term%'";
                    }
                }



            }else{
                $term = $search;
                $searchTermBits[] = "Page.name LIKE '%$term%' AND Page.content LIKE '%$term%'";

            }
            */
            // SEARCH IN Pages TABLE
            $this->loadModel('Page');
            // SAVE THE RESULT IN
            $d['pages'] = $this->Page->find('all', array(
                'conditions' => array(
                    'online'=>'1',
                    'type'=>'page',
                    'created <= NOW()',
                    'id > 1',
                    'OR' => array(
                        //implode(' AND ', $searchTermBits)
                        'Page.name LIKE'=>'%'.$search.'%',
                        'Page.content LIKE'=>'%'.$search.'%'
                        )
                    ),
                'fields' => array('name','content','created','id','type')
            ));
            //SEARCH IN Posts TABLE
            $this->loadModel('Post');
            $d['posts'] = $this->Post->find('all', array(
                'conditions' => array(
                    'online'=>'1',
                    'type'=>'post',
                    'created <= NOW()',
                    'OR' => array(
                        'Post.name LIKE'=>'%'.$search.'%',
                        'Post.content LIKE'=>'%'.$search.'%'
                        )
                    ),
                'fields'=> array('name','content','created','id','type','slug')
            ));
            // SEND THE VALUES TO THE VIEW
            $this->set($d);

        }else{
            echo 'e';
        }
    }

}

让它能够搜索“名称”和“内容”几个词

谢谢你的帮助 干杯你可以试试这个：

'OR' => array(
       'Post.name' IN ('name1', 'name2'),
       'Post.content' IN ('content1', 'content2')
)

显然，您可以将值放入如下数组：

$name_arr = array();
$name_arr[] = 'name1';
$name_arr[] = 'name2';

及之后：

'OR' => array(
           'Post.name' IN ($name_arr),
           'Post.content' IN ('content1', 'content2')
    )

更改$search变量

 $search = $this->request->data['Search']['key']; 
 // if keywords "red car" then it will pass to your query %red%car%;
 $search = str_replace(" ","%",$search);

现在，它将搜索同时包含两个单词的记录。

如果要搜索多个用空格分隔的单词，可以这样做

$searches = explode(" ", $search);
foreach ($searches as $search) {
   //put your search condition in here
}

你可以调查一下。如果正确设置索引，则可以运行以下查询：

根据文章中的“教程”选择id、匹配标题和正文

谢谢你，我要试一下：不要重新发明轮子，保持简单。

$searches = explode(" ", $search);
foreach ($searches as $search) {
   //put your search condition in here
}
