PHP AJAX receives database information

function updatepage(targetobject){if( == 4){

var response = ;Assign the value returned by ajax to the responseIf you want to use this variable, you can call it directly, or you can return it outside of the function.

response;Insert the value of the response into the HTML div, which is a simple function to get the PHP file after processing, please see the response, in fact, it is the effect you need.

The following is a pseudo**.

ajaxcall is your ajax function call, function(xhr) is the ** function when the ajax request is completed xhr is xmlhttprequest object.

Assign the string of the response to the ajaxval variable.

var ajaxval = ;

$get, $post to get the arguments.

Then just put it into the database.

You should print the passed parameters first, right?

print_r（$_post）;

How big a person's heart is, how big the stage is.

After the request is successful, empty the tbody (or define an id for the tbody and then manipulate the id) before putting the data.

In fact, what you write is too troublesome, you directly post request your return json data. In the js for loop tr tag, put the json data into td, and that's OK

Backstage**:

include("");Connect to the database.

print_r($_post);

echo '

echo 'post:' .$post["name"].'

echo 'txt:' .$post["txt"].'

mysql_query("insert into biao(name,txt) values ('','');

That's it, you can use double quotes to introduce variables, and when you introduce an array, you need to use the variable space or remove the double quotes in the array [if it's a single quote].

PHP can be used to make use of the predefined $post variable that can be used to get the data from method="post"or value from an ajax post request; For example, in the following example:

Commit with ajax: $post(url,,callback);

Then, in the php ** in the background of the server, you can use $post to get the value passed by ajax;

name = $_post['name'];

It is also possible to use the predefined $get and $request variables to receive the passed values; where $get is used to accept the pass value of the get request; $request is used to receive all the passed values including post and get.

Note that the passed values need to be filtered to ensure that the passed values do not cause SQL injection or XSS attacks.

It can be received with $post, and it can also be fetched with i in the tp framework. The values sent by ajax are passed in the form of arrays, so the server also receives them in the form of arrays.

Received as a form submission, $geg $ post $ request, can be received without the ** function.

can give you an example.

The private message link address is sent to you.

ABC data.

ajax_echo '"'.$_post['data'].'"Caught it. ';

if ($request['act'] == 'c**ignee_list')

* Check if the user is logged in.

If the user is already logged in, check if there is a default shipping address.

If you are not logged in, you will be redirected to the login and registration page.

if (empty($_session['direct_shopping']) session['user_id'] == 0)

echo $json->encode($result);

#addr_modify').click(function(),success:function(data)

else if( == 2)

#addr_modify').hide();

#addr_okbox').hide();

#addr_editbox').show();

;flow_

define('in_ecs', true);

if (!isset($_request['act']))

json = new json;

result = array('error' => 0, 'message' => '', 'content' => '');

result['message'] = 'Accepted, please continue';

echo $json->encode($result);

4 ways jQuery writes ajax. ,data,callback,type)

3、,data,callback,type)

4、jquery (selector).load(url,data,callback)

The first type is $ajax(, the data passed e.g. php is the argument, 100 is the value, with a colon in between, and the two arguments are separated by a comma.

Equivalent to innerhtml

;php page.

echo "php:".$_get['php'];The output value is a data value.

Type 4 $(document)ready(function(),function(){

For details, please refer to php100 109.

ajax pass the parameters over.,You can get it.。。

It's the same as a normal request.,w3cshool take a look.。

The frontend HTML is to use AJAX to send requests, generally send and receive data in JSON format, and then set setinterval to send a request every 1 second cycle, and the background is also very simple:

Just take the data sent back json encode() and echo json encode(array('time'=>time())

It doesn't have to be ajax, you can use timed tasks.

If you want to retrieve the database information like AJAX, then you need to read the database in PHP and let AJAX access it, you have PHP and get your data.

AJAX is called in JS and has nothing to do with PHP.
