How to parse large data via POST query

I am creating a webpage having Excel like features to create a Plan.For this i need to fill an initial form and click on submit button , then submit the form using ajax to a server side PHP script which inserts these records to a Mysql table.
But the issue is i can only transfer 1-2 records of table using the POST Query as there is a limit to it.What should i do in this case?Is there any other way of doing it without expanding the POST query limit?
My Front end code(.js)
</script>
buttons.save.addEventListener('click', function() {
var r1 = hot.countRows() - hot.countEmptyRows() - 1;
var c1 = hot.countCols()- 1 ;
var data = String(hot.getData(0,0,r1,c1));
data = data.replace(/,/g,'');
document.getElementById('all_data').value= JSON.stringify(hot.getData(0,0,r1,c1));
document.getElementById('colheaders').value=JSON.stringify(hot.getColHeader());
console.log(hot.getInstance());
var testplan_name = document.getElementById('feature_name').value;
var product = document.getElementById('product').value;
var release = document.getElementById('release').value;
var pv_engg = document.getElementById('pv_engg').value;
var pe_engg = document.getElementById('pe_engg').value;
var rd_engg = document.getElementById('rd_engg').value;
var tp_completion = document.getElementById('tp_completion').value;
var at_completion = document.getElementById('at_completion').value;
var all_headers = document.getElementById('colheaders').value;
var all_data = document.getElementById('all_data').value;
var maker = document.getElementById('maker').innerHTML;
var datastring = 'testplan_name='+testplan_name+'&product='+product+'&release='+release+'&pv_engg='+pv_engg+'&pe_engg='+pe
_engg+'&rd_engg='+rd_engg+'&tp_completion='+tp_completion+'&at_completion='+at_completion+'&headers='+all_headers+'&all_data='
+all_data+'&maker='+maker;
if(testplan_name=="" || pv_engg =='' || pe_engg== '' || rd_engg== '' || product=='' || release=='') {
else if(data=="") {
alert("For creating a testplan , you need to fill this table.");
}
else {
alert(datastring);
$.ajax({
url :"save_create_pro.php",
type :"POST",
data : datastring,
cache : false,
success :function(result) {
console.log(result);
alert(result);
alert("Form Submitted successfully");
},
error: function(jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
}
});
}
return false;
});
});
</script>
My Backend php code:
<?php
$dbh=mysql_connect('noiwebfarmo','abc','xyz');
if(! $dbh ) {
die('Could not connect: ' . mysql_error());
}
$database=mysql_select_db('testmohit');

$maker=$_POST['maker'];
$headers=stripslashes($_POST['headers']);
$all_data = stripslashes($_POST['all_data']);# to remove \ before " that occur when parsed through ajax
$headers=preg_replace('/\["/','',$headers);

Please provide a solution to insert large no. of rows of handson table without expanding the size of query string .What can be the solution of this problem.
Thanks in advance.

How can I count unread message in firebase chat messages in javascript

I developed a chat using firebase.
Not want to count all message that has unread status and display it to my list of users.
Here is my database.
As you can see in the image, I have status:"unread"
Here is what I did in javascript.
<script>
var ref = new Firebase("https://mosbeau-cd349.firebaseio.com/Users/<?php echo $ae; ?>/");
ref.on("value", function(snapshot) {
var names="";
var un=0;
for (x in snapshot.val()) {
var xRef = new Firebase("https://mosbeau-cd349.firebaseio.com/Users/<?php echo $ae; ?>/"+x+"/");
var messagesRef = new Firebase("https://mosbeau-cd349.firebaseio.com/Chats/"+x+" <?php echo $ae; ?>");
xRef.once("value", function(xsnapshot) {
var data = xsnapshot.val();
var name = data["cuname"];
//console.log(name);
messagesRef.on("value", function(ysnapshot) {
for (y in ysnapshot.val()) {
var yRef = new Firebase("https://mosbeau-cd349.firebaseio.com/Chats/"+x+" <?php echo $ae; ?>/"+y+"/");
yRef.once("value", function(zsnapshot) {
var ydata = zsnapshot.val();
var status = ydata["status"];
alert(status);
if(status=="unread"){
un++;
}
});
}
});
names += "<li style='padding:10px;border-bottom:1px solid#f2f2f2;'><a href='adminchat.php?id="+x+"&ae=<?php echo $ae; ?>&aeid=<?php echo $aeid; ?>&custo="+name+"'>"+name+" "+un+"</a></li>";
});
}
document.getElementById('results').innerHTML=names;
});
</script>
I can't get the total of unread message.
Please help me.

Use a query, a very common thing in Firebase:
...
//console.log(name);
// NEW
messagesRef.orderByChild("status").equalTo("unread").on("value", function(ysnapshot) {
var unread = ysnapshot.numChildren();
});
names += "<li style='padding:10px;border-bottom:1px solid#f2f2f2;'><a href='adminchat.php?id="+x+"&ae=<?php echo $ae; ?>&aeid=<?php echo $aeid; ?>&custo="+name+"'>"+name+" "+un+"</a></li>";
...
Assuming "https://mosbeau-cd349.firebaseio.com/Chats/"+x+" <?php echo $ae; ?>/" resolves to something like: "https://mosbeau-cd349.firebaseio.com/Chats/10736 ONLINESHOP/"
So all you're doing is getting this node, 10736 ONLINESHOP, and retrieving by its children having a child status with value unread.

Multiple sets of data insert at one call into separate divs by unique id AJAX

Currently when asking the server for data, when one single set is sent back like so
{"num":1,"notification_id":"818","notification_content":
"Lucy Botham posted a status on your wall","notification_throughurl"}
the div is inserted.
But lets say there's two sets with different notification id's like so
{"num":1,"notification_id":"818","notification_content":
"Lucy Botham posted a status on your wall","notification_throughurl"}
{"num":1,"notification_id":"819","notification_content":
"Lucy Botham posted a status on your wall","notification_throughurl"}
Nothing happens
So I'll cut the code down as to show and example of what I have
success: function(response){
if(response.notification_id > notification_id){
$("#notif_ui"+ notification_id).prepend('
<div class="notif_text"><div id="notif_actual_text-'+response['notification_id']+'"
class="notif_actual_text"><img border=\"1\" src=\"userimages/cropped'+response
['notification_triggeredby']+'.jpg\"
onerror=this.src=\"userimages/no_profile_img.jpeg\"
width=\"40\" height=\"40\" ><br /></div></div>');
i = parseInt($("#mes").text()); $("#mes").text((i+response.num));
}
I was toying with the idea of maybe using
$.each(response, function (i, val)
But I'm still unsure.
EDIT
Exact response how it shows
{"num":1,"notification_id":"823","notification_content":"Lucy Botham posted a status on your wall","notification_throughurl"
:"singlepoststreamitem.php?streamitem_id=703","notification_triggeredby":"85","notification_status":"1"
,"notification_time":"2015-11-08 04:16:26"}{"num":1,"notification_id":"824","notification_content":"Lucy
Botham posted a status on your wall","notification_throughurl":"singlepoststreamitem.php?streamitem_id
=704","notification_triggeredby":"85","notification_status":"1","notification_time":"2015-11-08 04:16
:27"}
AND MY WHILE LOOP
while($row = mysqli_fetch_assoc($com)){
if($row['notification_status']==1){
$num = mysqli_num_rows($com);
if($num){
$json['num'] = 1;
}else{
$json['num'] = 0;
}
$json['notification_id'] = $row['notification_id'];
$json['notification_content'] = $row['notification_content'];
$json['notification_throughurl'] = $row['notification_throughurl'];
$json['notification_triggeredby'] = $row['notification_triggeredby'];
$json['notification_status'] = $row['notification_status'];
$json['notification_time'] = $row['notification_time'];
echo json_encode($json);
}}

First you need to build an array of notifications, rather than a single one:
<?php
$json = array(
'notifications' => array()
);
while ($row = mysqli_fetch_assoc($com)) {
if ($row['notification_status'] == 1) {
$num = mysqli_num_rows($com);
$notification = array();
if ($num) {
$notification['num'] = 1;
} else {
$notification['num'] = 0;
}
$notification['notification_id'] = $row['notification_id'];
$notification['notification_content'] = $row['notification_content'];
$notification['notification_throughurl'] = $row['notification_throughurl'];
$notification['notification_triggeredby'] = $row['notification_triggeredby'];
$notification['notification_status'] = $row['notification_status'];
$notification['notification_time'] = $row['notification_time'];
$json['notifications'][] = $notification;
}
}
echo json_encode($json);
?>
Then you can access the notifications array from JavaScript:
success: function(response) {
$.each(response.notifications, function(i, notification) {
if (notification.notification_id > notification_id) {
$("#notif_ui" + notification_id).prepend('<div class="notif_text"><div id="notif_actual_text-' + notification['notification_id'] + '" class="notif_actual_text"><img border=\"1\" src=\"userimages/cropped' + notification['notification_triggeredby'] + '.jpg\" onerror=this.src=\"userimages/no_profile_img.jpeg\" width=\"40\" height=\"40\" ><br /></div></div>');
i = parseInt($("#mes").text());
$("#mes").text((i + response.num));
}
})
}
Note, completely untested, but hopefully you can see the difference!

Your php could be changed to
// you can just the the number of rows once outside the while loop
$num = mysqli_num_rows($com);
if($num){
$jsonNum = 1;
}else{
$jsonNum = 0;
}
while($row = mysqli_fetch_assoc($com)){
if($row['notification_status']==1){ // this would be unnecessary if you add it as a where conditional to your sql query
// add the num to the array to match your current data structure
$row['num'] = $jsonNum;
$json[] = $row;
}
}
echo json_encode($json);

Why my php array return only recent/last post activities

I create a jquery which sent data to a php file and after query(If any data found at sql) php return data to jquery by json_encode for append it.
Jquery sent two type data to php file:
1st: page id
2nd: post ids (a jquery array sent them to php file)
If I used print_r($_REQUEST['CID']); exit; on php file for test what he get from jquery, Its return and display all post ids well.
But if I make any reply on particular post, Its only return recent post reply.
That means, if I have 3 post like: post-1st, post-2nd, post-3rd ; my php return only post-3rd activities.
I want my script update any post reply when it submitted at sql.
my wall.php
// id is dynamic
<div class="case" data-post-id="111"></div>
<div class="case" data-post-id="222"></div>
<div class="case" data-post-id="333"></div>
//Check for any update after 15 second interval by post id.
<script type="text/javascript" charset="utf-8">
var CID = [];
$('div[data-post-id]').each(function(i){
CID[i] = $(this).data('post-id');
});
function addrep(type, msg){
CID.forEach(function(id){
$("#newreply"+id).append("<div class='"+ type +""+ msg.id +"'><ul>"+ msg.detail +"</ul></div>");
});
}
var tutid = '<?php echo $tutid; ?>';
function waitForRep(){
$.ajax({
type: "GET",
url: "/server.php",
cache: false,
data: {
tutid : tutid,
CID : CID
},
timeout:15000,
success: function(data){
addrep("postreply", data);
setTimeout(
waitForRep,
15000
);
},
error: function(XMLHttpRequest, textStatus, errorThrown){
setTimeout(
waitForRep,
15000);
}
});
}
$(document).ready(function(){
waitForRep();
});
</script>
server.php (may be problem in my array or something else)
while (true) {
if($_REQUEST['tutid'] && $_REQUEST['CID']){
foreach($_REQUEST['CID'] as $key => $value){
date_default_timezone_set('Asia/Dhaka');
$datetime = date('Y-m-d H:i:s', strtotime('-15 second'));
$res = mysqli_query($dbh,"SELECT * FROM comments_reply WHERE post_id =".$value." AND qazi_id=".$_REQUEST['tutid']." AND date >= '$datetime' ORDER BY id DESC LIMIT 1") or die(mysqli_error($dbh));
} // array close
$rows = mysqli_fetch_assoc($res);
$row[] = array_map('utf8_encode', $rows);
$data = array();
$data['id'] = $rows['id'];
$data['qazi_id'] = $rows['qazi_id'];
//ect all
// do something and echo $data['detail'] = $detail;
if (!empty($data)) {
echo json_encode($data);
flush();
exit(0);
}
} // request close
sleep(5);
} // while close

Try to declare CID array like this:
var CID = new Array();

It looks like you're looping through the CIDs and running an SQL query for each one, but you're only retrieving the results once, outside of the loop. You'll only get the last query's results if you run
$rows = mysqli_fetch_assoc($res);
outside of the CIDs foreach loop.
#koc:
Unfortunately, it won't be as simple as moving the closing loop bracket. If you're trying to retrieve multiple datasets in one AJAX call, then you'll need to handle multiple datasets in your AJAX's success callback, or in your addrep() function. Here's one way to do it, but you can do it many different ways depending on what you're ultimately trying to do:
while (true) {
if($_REQUEST['tutid'] && $_REQUEST['CID']){
$data = array();
foreach($_REQUEST['CID'] as $key => $value){
date_default_timezone_set('Asia/Dhaka');
$datetime = date('Y-m-d H:i:s', strtotime('-15 second'));
$res = mysqli_query($dbh,"
SELECT *
FROM comments_reply
WHERE post_id =".$value."
AND qazi_id=".$_REQUEST['tutid']."
AND date >= '$datetime'
ORDER BY id DESC LIMIT 1
") or die(mysqli_error($dbh));
$row = mysqli_fetch_assoc($res)
$data[] = array_map('utf8_encode', $row);
} // array close
//$rows = mysqli_fetch_assoc($res);
//$row[] = array_map('utf8_encode', $rows);
//$data = array();
//$data['id'] = $rows['id'];
//$data['qazi_id'] = $rows['qazi_id'];
//ect all
// do something and echo $data['detail'] = $detail;
if (!empty($data)) {
echo json_encode($data);
flush();
exit(0);
}
} // request close
sleep(5);
} // while close
then in your Javascript:
...
success: function(data){
for (var i=0, len=data.length; i<len; i++) {
addrep("postreply", data[i]);
}
setTimeout(waitForRep, 15000);
},
...
But again, that's just an example. I don't really know what your datasets look like or how you want the data to be passed around and used. This is just an idea that hopefully gets you going in the right direction.

how to loop all data on JSON

Hi I tried Looping my json_encode() to get all data that are related based on my query
the script is working fine but not the looping part
here's what I have so far:
$con3 = new PDO("mysql:host=". db_host .";dbname=db", db_username , db_password);
$con3->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$con4 = new PDO("mysql:host=". db_host .";dbname=chat_db", db_username , db_password);
$con4->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$sql5 = "SELECT * FROM users WHERE id = :rid LIMIT 1";
$stmt6=$con4->prepare($sql5);
$stmt6->bindValue( 'rid',$_GET['rid'], PDO::PARAM_STR);
$stmt6->execute();
foreach($stmt6->fetchAll()as $res)
{
$usern = $res['username'];
$user_lvl = $res['ulvl'];
}
$comb = $usern . $_GET['name'];
$sql6="SELECT msgid FROM thread WHERE combination1=:msgids OR combination2=:submsgids";
$msg_id = $con4->prepare($sql6);
$msg_id->bindParam(':msgids', $comb, PDO::PARAM_STR);
$msg_id->bindParam(':submsgids', $comb, PDO::PARAM_STR);
$msg_id->execute();
$msgd = $msg_id->fetchColumn();
$tbpre = $msgd;
$sql7 = "SELECT message_content, username , message_time, recipient FROM ".$tbpre."chat_conversation WHERE msgid=:chat";
$stmt7=$con3->prepare($sql7);
$stmt7->bindValue( 'chat', $msgd, PDO::PARAM_STR);
$stmt7->execute();
$message_query = $stmt7;
if(count($message_query) > 0) {
while($message_array = $stmt7->fetchAll(PDO::FETCH_ASSOC)) {
echo json_encode($message_array);
}
}
It only returns one data from my database..
this is my javascript for retrieving from my php side:
function AjaxRetrieve()
{
var rid = document.getElementById('trg').value,
data = {chat: uid, rid: rid, name: user};
$.get('includes/getChat.php', data, function (result) {
var res = $([]);
$.each(result[0], function(key, value) {
res = res.add($('<div />', {text : value}));
});
$("#clog").html(res);
}, 'json');
}

You just keep overwriting $json_string with each loop iteration.
What you want to do is save your DB data to array then encode.
$array = array();
if(count($message_query) > 0) {
while($message_array = $stmt7->fetchAll(PDO::FETCH_ASSOC)) {
$array[] = $message_array;
}
}
$json_string = json_encode($array);
echo $json_string;
It also appears that in your AJAX success handler function, you are not properly iterating the array.
Notice here that you only call $.each() on the first array element of the returned result set:
$.each(result[0], function(key, value) {
res = res.add($('<div />', {text : value}));
});
I would think you would want to iterate the entire result set like this:
$.each(result, function(rowKey, row) {
// row is single row of result set from database
// rowKey is numerical index of the row in the result set
// rowKey is probably not useful here
// You can just append new div to #clog with
// whatever content from row which you desire
// for example, this would insert message_content value
// in child div to #clog
$("#clog").append('<div>' + row.message_content + '</div>');
});

Try This.....
$i=0;
$fet=mysql_query('select * from tbl1 WHERE tbl1.id='20');
while($row=mysql_fetch_assoc($fet,MYSQL_ASSOC)){
$json[$i]['date']=$row['time'];
$i++;
}
echo json_encode($json);

Please use ->rowCount() to count rows:
$json = array();
if($message_query->rowCount() > 0) {
while($message_array = $stmt7->fetchAll(PDO::FETCH_ASSOC)) {
$json[] = $message_array;
}
}
echo json_encode($json);
You should use an array to store your message_arrays, so that you're not just replacing the same variable over and over.
