Get mysql table data one by one - php

I want to retrive mysql table data one by one.
data1
// wait 5 sec
data2
// wait 5 sec
Like this is there any way I can do That in php ?

Add sleep() to your loop to wait and pass seconds like sleep(5) how many seconds to wait.

Please use this code.
<script type="application/javascript">
function getData()
{
$.ajax({
method: "POST",
url: "getData.php",
data: { testParam: "1"}
}).done(function( msg ) {
$("#data").append(msg);
});
}
var myVar = setInterval(function(){ getData() }, 5000);
</script>
this code added in getData.php
function myfunction(){ echo "Hello, Nice to meet You";}
echo myfunction();

In this case you can use jQuery Ajax and create a function which call each 5 seconds:
<script>
function getData()
{
$.ajax({
method: "POST",
url: "getData.php",
data: { testParam: "1"}
}).done(function( msg ) {
$("#data").append(msg);
});
}
setInterval(getData(), 5000);
</script>
and you need an div which show data
<div id="data"></div>
and a php file which we named getData.php which provide data
<?php
echo '<div>Data</div>';
?>

calling a php function using ajax after interval of time

hi i am working on a codeigniter project. I want to execute a php function after an interval of 10seconds. When a user visits that specific page after 10 seconds i want that php function to be executed. In that php function i have set a counter which adds 1 to the specific table into the database. I have tried using AJAX but didnt get the desired result. Kindly explain me with examples as i am new in ajax. Thanks in advance...
#Majid Golshadi s answer is the right answer.
Working version is here
Please in view that is loaded all the time (like header_view.php)
add this few lines
<script type="text/javascript">
var _baseUrl = "<?= base_url() ?>";
</script>
This makes that your base_url is usable in JavaScript anywhere in page (but make sure to have it somewhere on "TOP" of page)
and literraly use #Majid Golshadi s answer in this way
$(document).ready(function() {
setTimeout(function() {
$.ajax({
url: _baseUrl + "/your/controller/param",
type: 'post',
data: {"token": "your_token"}, });
}, 10000);
});
using jquery this will be the easiest and fastest way to do that
`//setting timeout to 3 seconds = 3 thousand milli seconds
setInterval(function(){
//ajax call
$.ajax({
url: _baseUrl + "/controller_name/function_name/", //the url where you want to fetch the data
type: 'post', //type of request POST or GET
data: {"data": "value"}, }); //data passed to controller
},3000);`
in your controller you may use
function function_name(){
$var = $this->input->post();//getting data passed from ajax
//process here...
echo json_encode($var)//parses and returns the processed value
}
try this
setTimeout(function(){
$.ajax({
url: "<?php echo base_url('your/controller/address');?>",
type: 'post',
data: {"token": "your_token"},
});
}, 10000);
Example
in your view
$(document).ready(function(){
setTimeout(function(){
$.ajax({
url: "<?php echo base_url('MyController/Mymethod');?>",
type: 'post',
data: {"token": "12majid18"},
});
}, 10000);
});
and in Your Controller write method like this
public function Mymethod()
{
$token = $this->input->post('token');
if ( $token == '12majid18' )
{
/*call your model and insert your data in Table*/
}
}
you can try this:
window.jQuery(function(){
var y=setInterval(function() {
window.jQuery.post(url,{"token": "your_token"},function(res){
alert(res);
});
}, 10000);
});

Issue updating a <div> via AJAX refresh

I am dynamically generating a web page via scriptA.php. Within this page,
I have a div element #WatchContainer that needs to be updated every 5 minutes. The content for #WatchContainer is created by scriptB.php. To accomplish this, I have used "include" to embed scriptB.php in scriptA.php. The variable $sum is defined in scriptA.php and used by scriptB.php to update the content in #WatchContainer.
On initial page load, $sum is correctly passed from scriptA.php to scriptB.php. However, when #WatchContainer is updated via AJAX request, $sum is no longer passed to scriptb.php. The jQuery function is as follows:
function updateWatch() {
$.ajax({
url:"scriptB.php",
success: function(data) {
$("#WatchContainer").html(data);
}
});
}
var WatchInterval = setInterval("updateWatch()", 300000);
i don't see you passing any variable to scriptB.php via ajax.
i thinnk you should pass your $sum variable to scriptB.php via ajax using POST OR GET method
POST
function updateWatch(sum) {
$.ajax({
type:"POST",
url:"scriptB.php",
data:"sum="+sum,
success: function(data) {
$("#WatchContainer").html(data);
}
});
}
GET
function updateWatch(sum) {
$.ajax({
type:"GET",
url:"scriptB.php?sum="+sum,
success: function(data) {
$("#WatchContainer").html(data);
}
});
}
Try this with 3 seconds interval time, and make sure you include the library and other related stuff.
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function() {
var WatchInterval = setInterval(function() {
$.ajax({
url:"scriptB.php",
success: function(data) {
console.log(data);
}
});
},3000);
});
<script>

2 Mootools AJAX function at the same time?

I'm new to Javascript and Mootools and I was wondering if someone can help me learn by solving a problem that I currently have.
index.php has a form, which submit to it self and initiate this code
if($_POST['subbutton']=='Run')
{
$data=$object->do_compare();
}
I would like to know, how can I do a mootool ajax function, that will send the post['run]'
to a php script file ( data.call.php ) where the object reside and have it run.
however, I don't want any respond from data.class.php, as that object writes it's results to a txt file (data.txt)
the 2nd part,
would be an ajax function (that also run at the same time as the first ajax function) and reads a php file, every 5 seconds and bring the data back to index.php
so the squence of operations will be
index.php
form get clicked and start 2 ajax functions.
the first one, only submit the POST['run'] to a php script.
the second function, will go to another php file and get a respond from it every 5 seconds.
I didn't test the below, so use at your own risk. But that's pretty much the gist of it.
_form.addEvent('submit', function(event) {
// your first call
new Request.JSON({
url: "your-first-rpc",
data: {
subbutton: "Run"
},
onSuccess: function(response) {
// handle response here.
}
}).post();
// your second call which runs every 5 secs.
(function() {
new Request.JSON({
url: "your-second-rpc",
data: {
subbutton: "Run"
},
onSuccess: function(response) {
// handle response here.
}
}).post();
}).periodical(5000);
});
<script type="text/javascript">
window.addEvent('domready', function() {
$('dbform').addEvent('submit', function(e)
{
new Event(e).stop();
var intervalId =setInterval(function(){
var Ajax2 = new Request(
{
url: '/tools/getdata.php',
method: 'post',
data: 'read=true',
onComplete: function(response)
{
$('21').set('text', response);
}
}
).send();},1000);
var postString = 'subbutton=' + $('subbutton').value;
var Ajax = new Request({
url: '/tools/getdata.php',
method: 'post',
data: postString,
onRequest: function()
{
$('message').set('text', 'loading...');
},
onComplete: function(response)
{
$('message').set('text','completed');
clearInterval(intervalId);
},
onFailure: function() {
$('message').set('text', 'ajax failed');
}
}).send();
});
});
</script>

jQuery Ajax load data from database but doesn't display it

I have two files. One PHP-file, which contains a SQL-Select statement and returns the output as html. The second file is my index file which contains a div with the class "loadMembers" and some jquery code:
$(document).ready(function () {
function startInterval() {
var refreshId = setInterval(function () {
$.ajax({
url: 'sidebars/members.php',
type: 'html',
success: function (resp) {
$("div.loadMembers").html(resp);
}
});
}, 5000);
}
startInterval();
});
I want to refresh the div with database data in a 5 seconds interval. I tried it also with .load()...
The request contains some data but nothing from my database...
Where's the problem?
Thanks for any help :)
your request type can be get or post, not html, it should be dataType
url : 'sidebars/members.php',
type: 'POST', // or GET
dataType : 'html',

execute php file in jquery after a time delay in sequence

i have one jquery function which i need to work in following way
1. call a php file
2. log the values return by php file
3. have time delay
again repeat the above process for number of time
for this purpose i write bellow jquery and php file
<script type="text/javascript">
$(document).ready(function() {
listsValues="1,10,20";
n=0;
msgids = listsValues.split(',');
$.each(msgids, function() {
html="TEST MESSAGE";
n++;
setTimeout(function() {
$.ajax({
type: "POST",
url: "test1.php",
cache:false,
data:"id="+ msgids[n],
dataType:'json',
success: function(json)
{
var foo = json.foo;
uemail = foo.split(',');
console.log(uemail)
}
});
}, 1000);
});
});
</script>
and here is test1.php
<?php
$id=$_POST['id'];
$val="";
for($i=1;$i<=$id;$i++) {
$val.=$i;
}
$return["foo"] =$val;
print stripslashes(json_encode($return));
?>
but this is not working as a way i want, when i execute this script
i can see in firebug test1.php file executes (called) for 3times and after that values are written in console
as i said waht i want was
1. execute test1.php file
2. write value in console
3. give delay
then repeat
Thanks
I think you are searching something like this:
<script type="text/javascript">
function request(n) {
$.ajax({
type: "POST",
url: "test1.php",
cache:false,
data:"id="+ msgids[n],
dataType:'json',
success: function(json)
{
var foo = json.foo;
var uemail = foo.split(',');
console.log(uemail);
setTimeout(
function() {
request(n);
}
, 1000
);
}
});
}
$(document).ready(function() {
var listsValues="1,10,20";
var n=0;
var msgids = listsValues.split(',');
$.each(msgids, function() {
var html="TEST MESSAGE";
n++;
request(n);
});
});
</script>
