我需要从数据库中检索所有数据,并使用angular.js和PHP将它们绑定在文本字段中。我在下面解释我的代码。
的index.php
<?php
include_once 'dbconfig.php';
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>CRUD Operations With PHP and MySql - By Cleartuts</title>
<link rel="stylesheet" href="css/style.css" type="text/css" />
</head>
<body>
<center>
<div id="body">
<div id="content">
<table align="center">
<tr>
<th colspan="5"><a href="add_data.html">add data here.</a></th>
</tr>
<th>First Name</th>
<th>Last Name</th>
<th>City Name</th>
<th colspan="2">Operations</th>
</tr>
<?php
$sql_query="SELECT * FROM users";
$result_set=mysql_query($sql_query);
while($row=mysql_fetch_row($result_set))
{
?>
<tr>
<td><?php echo $row[1]; ?></td>
<td><?php echo $row[2]; ?></td>
<td><?php echo $row[3]; ?></td>
<td align="center"><a href="edit_data.php?edt_id=<?php echo urlencode($row[0]) ?>"><img src="images/pencil_small.png" align="EDIT" /></a></td>
<td align="center"><a href="javascript:delete_id('<?php echo $row[0]; ?>')"><img src="images/cross-small-icon.png" align="DELETE" /></a></td>
</tr>
<?php
}
?>
</table>
</div>
</div>
</center>
</body>
</html>
当用户点击编辑按钮时,它将重定向到下面给出的下一页(i.e-edit_data.php
),该页面包含将要编辑的所有数据。
edit_data.php:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" ng-app="edit_data">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>CRUD Operations With PHP and MySql - By Cleartuts</title>
<link rel="stylesheet" href="css/style.css" type="text/css" />
<script src="js/angularjs.js" type="text/javascript"></script>
<script src="js/update.js" type="text/javascript"></script>
</head>
<body>
<center ng-controller="updateController">
<div id="body">
<div id="content">
<table align="center">
<tr>
<td><input type="text" name="first_name" placeholder="First Name" ng-model="first_name" required /></td>
</tr>
<tr>
<td><input type="text" name="last_name" placeholder="Last Name" ng-model="last_name" required /></td>
</tr>
<tr>
<td><input type="text" name="city_name" placeholder="City" ng-model="city" required /></td>
</tr>
<tr>
<td>
<button type="submit" name="btn-update" ng-click="update_data();"><strong>UPDATE</strong></button>
</td>
</tr>
</table>
</div>
</div>
</center>
</body>
</html>
在此页面中,我需要在文本字段中显示所有提取的数据。
update.js:
var app=angular.module("edit_data", []);
app.controller("updateController",function($scope,$http){
$scope.errors = [];
$scope.msgs = [];
$scope.update_data=function(){
$http.post('js/update.php',{"first_name":$scope.first_name,"last_name":$scope.last_name,"city":$scope.city}
).success(function(data, status, headers, config){
if(data.msg!=''){
$scope.msgs.push(data.msg);
}else{
$scope.errors.push(data.error);
}
}).error(function(data, status) { // called asynchronously if an error occurs
// or server returns response with an error status.
$scope.errors.push(status);
});
}
});
我需要从我的Mysql数据库中检索这三个数据first_name,last_name,user_city
。请帮我解决这个问题。

制作连接到db的php文件并从db中检索给定的参数, 然后从角度调用它:
var app=angular.module("myApp", []);
app.controller("updateController",function($scope,$http){
$scope.errors = [];
$scope.msgs = [];
$scope.update_data=function(){
$http.post('update.php', {"first_name":$scope.first_name,"last_name":$scope.last_name,"city":$scope.ci ty}
).success(function(data, status, headers, config){
$scope.resultData = data;
}).error(function(data, status) { // called asynchronously if an error occurs
// or server returns response with an error status.
$scope.errors.push(status);
});
}
});
查看文件:
<div ng-controller="updateController" ng-app="myApp">
<div ng-repeat=item in resultData">
{{item.yourDbdata}}
</div>
</div>
你的更新php发布数据调用db和echo json_encode(查询结果)

在您的HTML中,您可以拥有 输入类型按钮,其值为&#34;编辑&#34;和事件ng-click =&#34; editUser()&#34;
在你的js控制器中发送一个请求到retrieveData(),即
$ scope.editUser = function(){ $ HTTP({ 网址:&#39; path_to_function / retrieveData /&#39 ;, 方法:&#39; POST&#39 ;, 数据:&#34;搜索=&#34; + $ scope.username , 标题:{&#39;内容类型&#39;:&#39; application / x-www-form-urlencoded&#39;} 成功(函数(响应,状态,标题,配置){ $ scope.result = response;
}); }
这里$ scope.username可以是任何东西,例如编辑特定用户的记录,$ scope.username将是该用户在数据库中获取的用户名。 5.必需的结果将在变量$ scope.result中的html上提供。
