请帮助搜索脚本

$("#search").on("keyup",function(){
    var search=$("#search").val();
    search=search.replace(/  +/g, ' ');
    if(search.length>=1){
        var result=search.split("");
        $.ajax({  
            type: 'POST',  
            url: "{{URL('/searchajax')}}", 
            data: 
                { 
                    search:result
                },
            success: function(data) {
                $("#searchresult").css("display","block");
                if(data.length>0){
                    for(var i=0;i<data.length;i++){
                        $.each(data[i], function( index, value ) {

如果有搜索词“iphone 7s”如何首先搜索“iphone”然后“7s”并获得所有结果的一个变量
如果有搜索词“iphone 7s”如何首先搜索“iphone”然后 “7s”并将所有结果都变为一个变量

Answer 1

如果我理解正确，您希望orWhere()对每个单词应用foreach对：

$words = explode(' ', $search);

$result = Product::query();

foreach ($words as $word) {
    $result = $result->orWhere('originalname', 'like', '%'.$word.'%')
                     ->orWhere('name', 'like', '%'.$word.'%');
}

$result = $result->orderby("products.table_id")->take(5)->get();

CodeIgniter的示例控制器

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *      http://example.com/index.php/welcome
     *  - or -
     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see https://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $this->load->model('common_model');
        $var1='engineering';

        $where=" id !='0'";
        $a['reco']=$this->common_model->get_entry_by_data('collages',false,$where);

        $this->load->view('welcome_message',$a);


    }


    public function ajaxcall()
    {   
    $searchval=$this->input->post('lalla');
    $this->load->model('common_model');

        $where="`city` like '%".$searchval."%' or `deparment` like '%".$searchval."%'";
        $a=$this->common_model->get_entry_by_data('collages',false,$where);


        $result='';
        $result="<table>
        <tr><td>name</td><td>city</td><td>deparment</td></tr>";
        if(!empty($a))
        { 
         foreach($a as $recos){
        $result.="<tr><td>". $recos['name']."</td><td>". $recos['city']."</td><td>". $recos['deparment']."</td></tr>"; 
        }
        }else{
            $result.="<tr><td>no result</td><td>no result</td><td>no result</td></tr>";

        }
        $result.="</table>";

        echo $result;



}
}

使用此自动填充功能，我在laravel 5.4中使用此代码

$('#search').on('input', function(){
    var search = $('#search').val(); //search input var

    if(search.length == 0){
        //do something if value of search box is empty
    } else {
        $('#search').autocomplete({
            source: function(request, response){
                $.ajax({
                    url: 'search', //route
                    data: { search:search },
                    dataType: 'json',
                    type: 'post',
                    success: function(data){
                        //here is your data
                    },
                    error: function(){
                        alert('Could not load the data');
                    }
                });
            }
        });
    }
});

使用ajax搜索，在数组
