Hello this is code snippet which i get from Jquery Ajax based search
I am done with everything, just the problem is the following script may not be sending the POST variable and its values or may be i am not properly fetching it.
<script type='text/javascript'>//<![CDATA[
$(window).load(function(){
$(document).ready(function() {
$("input[name='search_user_submit']").click(function() {
var cv = $('#newInput').val();
var cvtwo = $('input[name="search_option"]:checked').val();
var data = 'cv=' + cv + '&cvtwo=' + cvtwo; // sending two variables
$("#SearchResult").html('<img src="../../involve/images/elements/loading.gif"/>').show();
var url = "elements/search-user.php";
$.post(url, {
contentVar: data
}, function(data) {
$("#SearchResult").html(data).show();
});
});
});
});//]]>
</script>
In php file i have the following code:-
if (isset($_POST['cv']))
{
// My Conditions
}
else
{
// Show error
}
And its showing error, This means everything is correct just the post is not working properly, maybe.
Do the var data = 'cv=' + cv + '&cvtwo=' + cvtwo; // sending two variables will do the needful or we need to do any modifications. I know questions like this really annoy people, but what should i do i am stuck up.. #userD has really helped me a lot just, this part is left.
Since you're using $.post instead of $.ajax, your call should be:
$.post(url, data, function(response) {
/// ...
});
data must be a Javascript object, like this:
data = { "cv" : cv, "cvtwo" : cvtwo };
Check Jquery's documentation for more info:

Thank you very much for your help. I have the following file. The two alerts in the jquery event listener both work, but not the one inside the if (isset) block, as it is posting to itself. Thank you very much! I have abbreviated the code, everything is inside its proper tag.
<?php session_start();
include("config.php");
$myID = $_POST['chatid'];
$_SESSION['chateeID'] = $myID;
if(isset($_POST['inputmessage'])) {
echo '<script type="text/javascript">alert("got in here");</script>';
$sMessage = mysqli_real_escape_string($_POST['inputmessage']);
if ($sMessage != '') {
$sql = "INSERT INTO chatmessages (user_one_id, user_two_id, mymessage, action_user_id)
VALUES ('$user1', '$user2', '$sMessage', '$action_user_id')";
// Perform a query, check for error
if (!mysqli_query($con,$sql)){
echo '<script type="text/javascript">alert("'.mysqli_error($con).'");</script>';
}
}
}
<script>
$('#ChatInputBox').keydown(function (e) {
var keyCode = e.keyCode || e.which;
var txt = $("#ChatInputBox").val();
if (keyCode == 13 && txt!="") {
alert("txt is: "+txt);
$.post("inserttochat.php", { inputmessage: txt }, function(result){
alert("got to callback!");
});
}
});
</script>
I did this exactly the same way on another page but cannot find the discrepancy here.
After setting up your code on my development system I discovered that the short piece of script your PHP code is sending is being sent correctly, and being received correctly but not being executed by the jQuery AJAX code.
If you want that alert to show up in your page you need to place it in an HTML element
<div id="response"></div>
then
$.post("inserttochat.php", { inputmessage: txt }, function(result){
alert("got to callback!");
$("response").html(result);
});
A better way to do this is to echo some sort of status as a JSON object, then unpack that into an alert in Javascript.
echo json_encode((object)['status'=>'ok', 'msg'=>'All good']);
then
$.post("inserttochat.php", { inputmessage: txt }, function(result){
alert("Response: "+result.status+', '+result.msg);
},'json');
Note the json datatype added to the POST request*.
A better approach here is to standardise all your responses as JSON, and then add header("Content-type: application/json"); at the top of your PHP files. This will tell jQuery what the data is, rather than you having to force the issue in the browser.
I have an application that I'm writing that, in one aspect of it, you click on a checkmark to complete a task, a popup window is displayed (using bootstrap), you enter your hours, and then that is sent to a PHP page to update the database. I'm using FF (firebug) to view the post. It's coming up red but not giving me an error. The only thing I'm doing is echoing out "sup" on the PHP page, and it's still showing errors, and I can't figure out why.
This is my initial click function:
$('.complete').on('click', function(event) {
var id = $(this).attr('data-id');
var tr = $(this).parent().parent();
var span = $(tr).children('td.task-name');
var r = (confirm('Are you sure you want to complete this task?'));
if (r){
addHours(id);
} else {
return false;
} // end else
});
That works fine, and it fires my next function which actually fires the bootstrap modal:
function addHours(id) {
var url = 'load/hours.php?id='+id;
$.get(url, function(data) {
$('<div class="modal hide fade in" id="completeTask">' + data + '</div>').modal()
.on('shown', function() {
pendingTask(id);
}); // end callback
}).success(function() {
$('input:text:visible:first').focus();
});
} // end function
This is also working, and the modal is displayed just fine. However, whenever I post the form to my logic page, it fails for no reason. This is the function to post the form to the logic page:
function pendingTask(id) {
$('.addHours').on('click', function(event) {
var formData = $('form#CompleteTask').serializeObject();
$.ajax({
url:'logic/complete-with-hours.php',
type: 'POST',
dataType: 'json',
data: formData,
success: function(data) {
if (data.status == 'error') {
$(this).attr('checked', false);
//location.reload();
} // end if
else {
$(this).attr('checked', true);
//location.reload();
} // end else
},
dataType: 'json'
});
}); // end click
} // end function
When this is fired, I see this in my Firebug console:
I know this is a lot of information, but I wanted to provide as much information as I could. Every other post function in the application is working fine. It's just this one. Any help would be appreciated.
Thanks in advance.
The jQuery.ajax data parameter takes a simple object of key value pairs. The problem could be that the object created by serializeObject() is too complex. If that's the case, you could either process the formData object to simplify it or try data: JSON.stringify(formData)
Does serializeObject() even exist in jQuery? is that a function you wrote yourself? Can you use jQuery functions like serialize() or serializeArray() to serialize the form data and see how it goes.
Usually the red indicates a 404 response error. We can't tell in this screen shot. Check your php code by directly calling the requested page and getting a proper response.
Also make sure your dataType is application/json which is the proper mime type header (though I don't think this is causing the error). You also should only have dataType once (you have it again at the bottom)
I figured it out. I changed the post type from the structure I entered above to a standard post:
$("#CompleteTask").validate({
submitHandler: function(form) {
var hours = $('#hours').val();
$.post('logic/complete-with-hours.php', {'hours': hours, 'id':id},
function(data){
if (data.status == 'success') {
$(checkmark).attr('checked', false);
$('.message').html(data.message).addClass('success').show();
} // end if
if (data.status == 'error') {
$('.message').html(data.message).addClass('error').show();
} // end else
},
"json"
); //end POST
} // end submit handler
}); // end validate
That seemed to do the trick
So I have this chunk of code here (below). It waits for a video to finish playing and then it looks up a cookie, sends that info to a php script through ajax, gets back a url from json, and reloads an iframe with a new url.
So I think you'll agree, it's sorta a lot going on.
Its purpose is to advance ONE forward in a playlist of videos. I am trying to create a button area where a user can click a >> sort of button and go forward. Which is exactly what this function does.
Rather than starting from scratch with a new function, is there a way to activate all of the above function functionality (ajax and all) when the user clicks that button?
<script>
function ready(player_id)
{
$f('play').addEvent('ready', function()
{
$f('play').addEvent('finish', onFinish);
});
function onFinish(play)
{
var now_video_var = $.cookie('now_video');
console.log ('player ' + now_video_var + ' has left the building');
var intermediate_integer = parseInt(now_video_var);
var request2 = $.ajax({
url : "geturl.php",
data : {intermediate_integer : intermediate_integer},
type : 'post'
}).done(function(data) {
var gotfrom = jQuery.parseJSON(data);
var NEWURL = gotfrom[1] ;
console.log(gotfrom);
console.log(data);
console.log(gotfrom[1]);
var theiframeforrealyo = document.getElementById('play');
$(theiframeforrealyo).attr("src", "http://player.vimeo.com/video/" + gotfrom[1] +"?api=1&player_id=play&title=0&byline=0&portrait=0&autoplay=1");
var new_video_var = intermediate_integer +1;
$.cookie('now_video', new_video_var);
console.log ( 'cookie function ok: the cookie is....');
console.log ($.cookie('now_video'));
});
}
}
window.addEventListener('load', function() {
//Attach the ready event to the iframe
$f(document.getElementById('play')).addEvent('ready', ready);
});
</script>
I am using JQuery and AJAX to post to a PHP file which will eventually parse the data and insert it in a database.
I'm having issue display trying to see what's wrong with my javascript that it will not post the PHP file.
I know it is not posting because I don't recieve and email which is the first function in the PHP file.
JS
$(document).ready(function() {
var ptitle = $("#name").val();
var pdesc = $("#desc").val();
var pemail = $("#email.").val();
$('#submit').click(function() {
sendValue(ptitle, pdesc, pemail);
});
});
function sendValue(ptitle, pdesc, pemail) {
$.post("<?=MOLLY.'update.php'?>", {
stitle: ptitle,
sdesc: pdesc,
semail: pemail
}, function(data) {
//
}, "json");
}
PHP
mail($myemail,'test','test');
if ($_POST){
$title = $_POST['stitle'];
$email = $_POST['semail'];
mail($myemail,$email,$title);
}
You have a typo:
$(document).ready(function() {
var ptitle = $("#name").val();
var pdesc = $("#desc").val();
var pemail = $("#email.").val(); // <---- I assume you meant "#email".
$('#submit').click(function() {
sendValue(ptitle, pdesc, pemail);
});
});
Start by checking that your PHP file runs, replace the content with something like:
PHP
echo "Im running";
Then in your JS do:
$.post("<?=MOLLY.'update.php'?>", function(data) {
console.log(data);
}, "json");
and see if the message is returned and logged in the console.
If it is, check your $_POST by echoing back the values you sent, also echo back your email variable to see that it outputs correctly.
If it all works fine, you need to check if your server is set up correctly for the mail command to actually be able to send an email, as the problem is most likely serverside when everything else is eliminated.
Oh, and you should do what cillosis says, use isset and check something in the $_POST superglobal, not just a if($_POST), but since your running the mail function before that in your PHP, that's probably not your main problem.
I want to use $.post function of jquery to do a div refresh, only if the content returned in the json data from the php script is modified. I know that ajax calls with $.post are never cached. Please help me with $.post, or $.ajax if it is not possible with $.postor any other method with which this is possible.
Thanks
Why don't you cache the response of the call?
var cacheData;
$.post({.....
success: function(data){
if (data !== cacheData){
//data has changed (or it's the first call), save new cache data and update div
cacheData = data;
$('#yourdiv').html(data);
}else{
//do nothing, data hasan't changed
This is just an example, you should adapt it to suit your needs (and the structure of data returned)
var result;
$.post({
url: 'post.php'
data: {new:'data'}
success: function(r){
if (result && result != r){
//changed
}
result = r;
}
});
Your question isn't exactly clear, but how about something like this...
<script type="text/javascript">
$(document).ready(function(){
$("#refresh").click(function(){
info = "";
$.getJSON('<URL TO JSON SOURCE>', function(data){
if(info!=data){
info = data;
$("#content").html(data);
}
});
});
});
</script>
<div id="content"></div>
<input id="refresh" type="submit" value="Refresh" />
I think you should use .getJSON() like I used it there, it's compact, and offers all the functionality you need.
var div = $('my_div_selector');
function refreshDiv(data){
// refresh the div and populate it with some data passed as arg
div.data('content',data);
// do whatever you want here
}
function shouldRefreshDiv(callback){
// determines if the data from the php script is modified
// and executes a callback function if it is changed
$.post('my_php_script',function(data){
if(data != div.data('content'))
callback(data);
});
}
then you can call shouldRefreshDiv(refreshDiv) on an interval or you can attach it to an event-handler
