How PHP+Ajax realizes real-time editing of tables
This time I will show you how PHP+Ajax realizes real-time editing of tables. What are the precautions for PHP+Ajax to realize real-time editing of tables. The following is a practical case, let’s take a look.
What a cool thing it would be if we could operate all the data in a table on this page (it’s so fun to use)!
This function can be achieved using Ajax. Without further ado, let me post the demo I wrote below, haha. I am more accustomed to the TP framework (3.2) I use.
First is the HTML code part:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>AJAX实时编辑</title>
<script src="PUBLIC/jquery-1.7.2.min.js"></script>
</head>
<body>
<center>
<table border="1" width="1000" id="g_table">
<tr>
<!-- <th>ID</th> -->
<th>TAB1</th>
<th>TAB2</th>
<th>TAB3</th>
<th>TAB4</th>
<th><span onclick="add()">添加</span></th>
</tr>
<foreach name="tablist" item="vv">
<tr>
<!-- <td>{$vv.id}</td> -->
<input type="hidden" name="id" value="{$vv.id}">
<td>{$vv.tab1}</td>
<td>{$vv.tab2}</td>
<td>{$vv.tab3}</td>
<td>{$vv.tab4}</td>
<td><span onclick="del(this)" id="del">删除</span><span onclick="edit(this)" id="edit">修改</span></td>
</tr>
</foreach>
</table>
</center>
</body>
<script>
var g_table = $("#g_table");
function add(){
var addRow = $("<tr></tr>");
g_table.append(addRow);
for(var i = 0;i < 4;i++){
var col_td = $("<td><input type='text' /></td>");
addRow.append(col_td);
}
var col_opt = $("<td></td>");
var confirmBtn = $("<a href='javascript:;'>确认</a>");
var cancelBtn = $("<a href='javascript:;'>取消</a>");
cancelBtn.click(function(){
window.location.reload();
});
confirmBtn.click(function(){
var currentRow = $(this).parent().parent();
var input_files = currentRow.find("input");
var post_files = {};
for(var i = 0 , j = input_files.length;i < j;i++){
post_files['clo_' + i] = input_files[i].value;
}
// $.post("{:U('ajax/add')}",post_files,function(msg){
// debugger;
// })
$.ajax({
type: 'post',
url : "{:U('ajax/add')}",
data: {post_files},
success:function(msg){
alert(msg);
window.location.reload();
}
})
});
col_opt.append(confirmBtn);
col_opt.append(cancelBtn);
addRow.append(col_opt);
}
function del(obj){
var id = $(obj).parent().prev().prev().prev().prev().prev().val();
$.ajax({
type: 'post',
url: "{:U('ajax/del')}",
data: {id:id},
success:function(msg){
alert(msg);
}
})
$(obj).parent().parent().remove();
}
function edit(obj){
var id = $(obj).parent().prev().prev().prev().prev().prev().val();
for(var i = 1;i < 5;i++){
var temp = "<td><input type='text' value='" + $(obj).parent().parent().children().eq(i).html() + "'/></td>";
$(obj).parent().parent().children().eq(i).replaceWith(temp);
}
var confirmBtn1 = $("<span id='confirm'>确认</span>");
var cancelBtn1 = $("<span onclick='back()'>取消</span>");
confirmBtn1.click(function(){
var currentRow = $(this).parent().parent();
var input_files = currentRow.find("input");
var post_files = {};
for(var i = 0 , j = input_files.length;i < j;i++){
post_files['clo_' + i] = input_files[i].value;
}
$.ajax({
type: 'post',
url : "{:U('ajax/edit')}",
data: {post_files:post_files,id:id},
success:function(msg){
alert(msg);
window.location.reload();
}
})
});
$(obj).prev().replaceWith(confirmBtn1);
$(obj).replaceWith(cancelBtn1);
}
function back(){
location.reload();
}
</script>
</html>The following is the code in controller:
<?php
namespace Home\Controller;
use Think\Controller;
class AjaxController extends Controller{
public function index(){
$tab = M('table');
$tablist = $tab->select();
$this->assign('tablist',$tablist);
$this->display();
}
public function del(){
$map['id'] = $_POST['id'];
$tab = M('table');
$info = $tab->where($map)->delete();
if($info){
$this->ajaxReturn("删除成功");
}else{
$this->ajaxReturn("删除失败");
}
}
public function add(){
$map['tab1'] = $_POST['post_files']['clo_0'];
$map['tab2'] = $_POST['post_files']['clo_1'];
$map['tab3'] = $_POST['post_files']['clo_2'];
$map['tab4'] = $_POST['post_files']['clo_3'];
$tab = M('table');
$res = $tab->add($map);
if($res){
$this->ajaxReturn("添加成功");
}else{
$this->ajaxReturn("添加失败");
}
}
public function edit(){
$id = $_POST['id'];
$map['tab1'] = $_POST['post_files']['clo_1'];
$map['tab2'] = $_POST['post_files']['clo_2'];
$map['tab3'] = $_POST['post_files']['clo_3'];
$map['tab4'] = $_POST['post_files']['clo_4'];
// dump($map);exit;
$tab = M('table');
$res = $tab->where('id='.$id)->save($map);
if($res){
$this->ajaxReturn("更新成功");
}else{
$this->ajaxReturn("更新失败");
}
}

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
