This article mainly introduces the method of ThinkPHP to implement ajax-like official website search function. The example demonstrates the background query function and the method of submitting search data through front-end Ajax. It is a very practical skill. Friends who need it can refer to it

The example in this article describes how ThinkPHP implements the ajax imitation official website search function. Share it with everyone for your reference.

The specific implementation method is as follows:

Backend code:

//搜索,如果在1不在0  
function search(){  
    $keyword = $_POST['search'];  
    $Goods=M('goods');  
  //这里我做的一个模糊查询到名字或者对应的id,主要目的因为我这个系统是  
  //商城系统里面用到直接看产品ID  
    $map['goods_id|goods_name']  = array('like','%'.$keyword.'%');  
    // 把查询条件传入查询方法  
    if($goods=$Goods->where($map)->select())  
     {  
              $this->ajaxReturn($goods,'查询成功!',1);  
     }else{  
              $this->ajaxReturn($data,"查询失败,数据不存在!",0);  
 }  
}

Front-end code:

$(document).ready(function(){  
   $(".show_message").hide();  
   var $search=$('#search_box');  
   $("#submit_from").click(function(){  
    if($("#search_box").attr("value")=='')  
    {  
        //alert('请输入文字!');  
        $(".show_message").html('错误提示:搜索框文本不能为空!');  
        $(".show_message").fadeIn(1000);  
        $(".show_message").fadeOut(1000);  
        $search.focus();  
        //return false;  
    }else{  
        //开始ajax执行数据  
        $.ajax({  
            type: "POST",  
            url:"/index.php/Goods/search",  
            data:{  
                search:$search.val()  
            },  
            dataType: "json",  
            success: function (data) {  
    if (data.status == 1) {  
            //alert(data.info);  
            var html='';  
                    $.each(data.data,function(no,items){      
                    html+='';  
                    });  
                    html+="  
'+items.goods_id+' '+items.goods_name+' '+items.add_time+' '+items.brand+' '+items.price+'";      
                     $(".goods-list").html(' ').html(html);  
                   // alert(html);  
    }  
    else if (data.status == 0) {  
        $(".show_message").show();  
        $(".show_message").html(data.info);  
                    $(".show_message").fadeOut(3000);  
    //    alert(data.info);  
          return false;  
        }

How can you check if a PHP session has already started?How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
