I'm at lost on what is the way to do this. So basically i got a multiple comment form like this :
#foreach($lists as $list)
//some views
<form class="commentForm">
<input type="text" class="commentBox" name="comment" />
<input type="submit" class="submitBtn" value="Comment" />
</form>
#endforeach
And i want to implement AJAX so that every time user comment something, the page won't reload. My current route for submitting the comment is :
Route::post('list/{listID}/comment', 'ListController#comment');
And i don't know how to pass that ID from the view to AJAX and then back to controller. I tried to obvious one, use 'list/{{ $list->id }}/comment' in the AJAX url, that didn't work. Also tried some other things but basically all for naught.
Thank you in advance !
EDIT : My AJAX code :
$(document).ready(function(){
$(document).on("submit", '.commentForm', function(e){
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
}
});
var data = $(this).serialize();
var me= this;
$.ajax({
type: 'POST',
url: 'posts/{{ $auction->id }}/comment',
data: data,
datatype: 'JSON',
success:function(data){
console.log(data);
},
error:function(data){
console.log(data);
}
});
return false;
})
});
I just console.log-ing the outputs for now to see whether it works not.
In laravel, they use blade templating. I dont know where you put your ajax code, but these bracket: {{ }}, {!! !!} only will be considered as templating when you use the extension .blade.php.
In laravel you can use .php under resource/views as the html template, but the one inside {{ }}, {!! !!}, and other blade syntax will be treated as normal text instead of being interpreted again. If you need, usually i will make the layout will be something like this:
<html>
<head>
#yield("sytles")
#yield("additionalstyles")
#yield("includestyles")
................//as many as you need
</head>
<body>
<div>#yield("content")</div>//content here
#yield("scripts")
#yield("additionalscripts")
#yield("includescripts")
................//as many as you need
</body>
</html>
and then in the view, when i need to make ajax request, i will enclose it inside the #section("script") #stop or whichever the yield that haven't been used yet, so for example the view part of your code maybe will be like this after using this template:
#extends("layout")
#section("content")
#foreach($lists as $list)
//some views
<form class="commentForm">
<input type="text" class="commentBox" name="comment" />
<input type="submit" class="submitBtn" value="Comment" />
</form>
#endforeach
#stop
#section("additionalscript")
<script>
$(document).ready(function(){
$(document).on("submit", '.commentForm', function(e){
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
}
});
var data = $(this).serialize();
var me= this;
$.ajax({
type: 'POST',
url: 'posts/{{ $auction->id }}/comment',
data: data,
datatype: 'JSON',
success:function(data){
console.log(data);
},
error:function(data){
console.log(data);
}
});
return false;
})
});
</script>
#stop
In this way, your
url: 'posts/{{ $auction->id }}/comment',
will going to be rendered as something like
url: 'posts/hansishandsome/comment',
Hope this help
I recommend using jQuery's .data() feature, so in the foreach loop you do this:
<form class="commentForm" data-id="{{$list->id}}">
<input type="text" class="commentBox" name="comment" />
<input type="submit" class="submitBtn" value="Comment" />
</form>
Then one listener to rule them all:
$(document).on("submit", '.commentForm', function(e){
e.preventDefault();
var comment_id = $(this).data('id');
console.log('comment id = ',comment_id);
$.ajax({
type: 'POST',
url: 'posts/' + comment_id + '/comment',
//etc...
});
You can do following steps:
Add one hidden field with value as Listid in form like:
<input type="hidden" id="listId" value="{{$list->id}}" />
And then you can use it in ajax call like:
$listId = $("#listId").val();
These are the following ways you can do it
Create a hidden input
<input type="hidden" id="listid" name="listid" value="{{ $list->id }}">
and read the value through JQuery
var listid = $('#listid').val();
Create a JSON object and read it in your
<script>
var list = {
id : {{ $list->id }} //you can also add other variables in the object
}
</script>
And in your js file use the list object
NOTE: the list object must initialized before you run your script
$.post('list/' + list.id + '/comment', data);

Please I am new to jQuery so i just copied the code:
<div id="container">
<input type="text" id="name" placeholder="Type here and press Enter">
</div>
<div id="result"></div>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#name').focus();
$('#name').keypress(function(event) {
var key = (event.keyCode ? event.keyCode : event.which);
if (key == 13) {
var info = $('#name').val();
$.ajax({
method: "POST",
url: "action.php",
data: {name: info},
success: function(status) {
$('#result').append(status);
$('#name').val('');
}
});
};
});
});
</script>
And here is the php code:
<?php
if (isset($_POST['name'])) {
echo '<h1>'.$_POST['name'];
}
?>
Its Working perfectly but now i want to have more than one input field like this:
<input type="text" id="name" >
<input type="text" id="job">
but i don't know how to run the jQuery code for the 2 input fields so that it can transfer them to the php page. Please i need help
You can pass multiple values using data param of ajax request like this.
$.ajax({
method: "POST",
url: "action.php",
data: {
name: $('#name').val(),
job: $('#job').val()
},
success: function(status) {
$('#result').append(status);
$('#name, #job').val(''); // Reset value of both fields
}
});
You need to change your code with some addition in html and JS.
Wrap your inputs in form tag. and add a preventDefault on submit.
Use jQuery .serialize() method
and event.preventDefault()
event.preventDefault() : If this method is called, the default
action of the event will not be triggered. (it will prevent page
reload / redirection) to any page.
.serialize() : Encode a set of form elements as a string for
submission.
serialized string output will be like key=value pair with & separated. :
name=john&job=developer.....
HTML
<form id="myform">
<input type="text" id="name" placeholder="Type here and press submit">
<input type="text" id="job" placeholder="Type here and press submit">
<input type="submit" name="submit" value="Submit Form">
</form>
JS
$(document).ready(function() {
$('#myform').submit(function(event) {
event.preventDefault();
var serialized = $('#myform').serialize();
$.ajax({
method: "POST",
url: "action.php",
data: serialized,
success: function(status) {
$('#result').append(status);
$('#myform').reset();
}
});
});
});
issues are still there...pls help
I am unable to load external file while using AJAX jquery. I want to use Jquery ajax to pop up form then validate, enter data in mysql. but starting from a simple ajax function. kindly let me know where i am going wrong
<link rel="stylesheet" type="text/css" media="all" href="test_style.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#ajax-contact-form").submit(function(){
var str = $(this).serialize();
$.ajax(
{
type: "POST",
url:"contact.php",
data: str,
success:function(result)
{
$("#div1").html(result);
}
});
});
});
</script>
</head>
<body>
<div id="contact_form">
<form id="ajax-contact-form" name="contact" action="">
<fieldset>
<label for="name" id="name_label">Name</label>
<input type="text" name="name" id="name" size="30" value="" class="text-input" />
<label class="error" for="name" id="name_error">This field is required.</label>
<INPUT class="button" type="submit" name="submit" value="Send Message">
</fieldset>
</form>
</div>
</body>
</html>
and contact.php file is
<?php
echo "Hello";
?>
You need to return false; to prevent the form from submitting and refreshing the page and check if your $("#div1") is missing.
$(document).ready(function(){
$("#ajax-contact-form").submit(function(){
var str = $(this).serialize();
$.ajax(
{
type: "POST",
url:"contact.php",
data: str,
success:function(result)
{
$("#div1").html(result);
}
});
return false;
});
});
Simple. Since you are posting your form through ajax, you must prevent the default form submit by returning a false inside the submit method. Below is the correct version:
<script>
$(document).ready(function(){
$("#ajax-contact-form").submit(function(){
var str = $(this).serialize();
$.ajax({
type: "POST",
url:"contact.php",
data: str,
success:function(result) {
$("#div1").html(result);
}
});
return false;
});
});
</script>
You can use a more simple form of post request as follows:
$.post("url",{var1: value1, var2: value2},function(data,status){
if(status=='success')
alert(data);
});
the second argument you can pass as many using this post request. The first argument url, if ofcourse relative to the document in which this js is loaded or you can give the exact url on the server.
According to your php file, data=='Hello'.
Similar is the procedure for any GET request also.
Make sure you are missing the div1
please use
<div id="div1"><div>
I've been racking my brains for days looking at examples and trying out different things to try and get my form to submit with Ajax without a page refresh. And Its not even sending the data now.. I don't know what I'm doing wrong..Can someone run through my ajax and form please.
Toid is the users id and newmsg is the text in which the user submits. The two values get sent to the insert.php page.
I would really appreate the help. I'm new to Ajax, and I look at some of it and don't have a clue. If I finally got it working, It may help me realize what I've done wrong. I am looking up tutorials and watching videos..but it can be very time consuming for something that would be simple to someone in the know on here. It maybe that I've got the wrong idea on the ajax and it makes no sense at all, sorry about that.
<script type="text/javascript">
$(document).ready(function(){
$("form#myform").submit(function() {
homestatus()
event.preventDefault();
var toid = $("#toid").attr("toid");
var content = $("#newmsg").attr("content");
$.ajax({
type: "POST",
url: "insert.php",
data: "toid="+content+"&newmsg="+ newmsg,
success: function(){
}
});
});
return false;
});
</script>
<form id="myform" method="POST" class="form_statusinput">
<input type="hidden" name="toid" id="toid" value="<?php echo $user1_id ?>">
<input class="input" name="newmsg" id="newmsg" placeholder="Say something" autocomplete="off">
<div id="button_block">
<input type="submit" id="button" value="Feed" onsubmit="homestatus(); return false" >
</div>
</form>
INSERT.PHP
$user1_id=$_SESSION['id'];
if(isset($_POST['toid'])){
if($_POST['toid']==""){$_POST['toid']=$_SESSION['id'];}
if(isset($_POST['newmsg'])&isset($_POST['toid'])){
if($_POST['toid']==$_SESSION['id']){
rawfeeds_user_core::create_streamitem("1",$_SESSION['id'],$_POST['newmsg'],"1",$_POST['toid']);
}else{
rawfeeds_user_core::create_streamitem("3",$_SESSION['id'],$_POST['newmsg'],"1",$_POST['toid']);
Try using firebug to identify bugs in your code. It's a really good companion for developing javascript. Nearly all of your bugs led to error messages in the firebug console.
You had several errors in your code, here is the corrected version:
$(document).ready(function(){
$("form#myform").submit(function(event) {
event.preventDefault();
var toid = $("#toid").val();
var newmsg = $("#newmsg").val();
$.ajax({
type: "POST",
url: "insert.php",
data: "toid=" + content + "&newmsg=" + newmsg,
success: function(){alert('success');}
});
});
});
And here the corrected html:
<form id="myform" method="POST" class="form_statusinput">
<input type="hidden" name="toid" id="toid" value="<?php echo $user1_id; ?>">
<input class="input" name="newmsg" id="newmsg" placeholder="Say something" autocomplete="off">
<div id="button_block">
<input type="submit" id="button" value="Feed">
</div>
</form>
Actually onsubmit event has to be used with form so instead of
<input type="submit" id="button" value="Feed" onsubmit="homestatus(); return false" >
it could be
<form id="myform" method="POST" class="form_statusinput" onsubmit="homestatus();">
and return the true or false from the function/handler, i.e.
function homestatus()
{
//...
if(condition==true) return true;
else return false;
}
Since you are using jQuery it's better to use as follows
$("form#myform").on('submit', function(event){
event.preventDefault();
var toid = $("#toid").val(); // get value
var content = $("#newmsg").val(); // get value
$.ajax({
type: "POST",
url: "insert.php",
data: "toid=" + toid + "&newmsg=" + content,
success: function(data){
// do something with data
}
});
});
In this case your form should be as follows
<form id="myform" method="POST" class="form_statusinput">
...
</form>
and input fields should have a valid type and value attribute, Html form and Input.
I think you should read more about jQuery.
Reference : jQuery val and jQuery Ajax.
change the form to this
<form id="myform" ... onsubmit="homestatus(); return false">
you don't need the onsubmit attribute on the submit button, but on the form element instead
homestatus might be out of scope
function homestatus () {
var toid = $("#toid").attr("toid");
var content = $("#newmsg").attr("content");
$.ajax({
type: "POST",
url: "insert.php",
data: "toid="+content+"&newmsg="+ newmsg,
success: function(){
}
});
}
This isn't tested, but try this (I annotated some stuff using comments)
<script type="text/javascript">
$(document).ready(function(){
$("form#myform").submit(function(event) {
// not sure what this does, so let's take it out of the equation for now, it may be causing errors
//homestatus()
// needed to declare event as a param to the callback function
event.preventDefault();
// I think you want the value of these fields
var toid = $("#toid").val();
var content = $("#newmsg").val();
$.ajax({
type: "POST",
url: "insert.php",
data: "toid="+toid +"&newmsg="+ content,
success: function(){
}
});
return false;
});
});
</script>
<form id="myform" method="POST" class="form_statusinput">
<input type="hidden" name="toid" id="toid" value="<?php echo $user1_id ?>">
<input class="input" name="newmsg" id="newmsg" placeholder="Say something" autocomplete="off">
<div id="button_block">
<input type="submit" id="button" value="Feed" / >
</div>
</form>
It's a lot easier to let .serialize() do the work of serializing the form data.
The submit handler also needs event as a formal parameter, otherwise an error will be thrown (event will be undefined).
With a few other changes, here is the whole thing:
<script type="text/javascript">
$(document).ready(function(){
$("form#myform").submit(function(event) {
event.preventDefault();
homestatus();
var formData = $(this).serialize();
$.ajax({
type: "POST",
url: "insert.php",
data: formData,
success: function(data) {
//...
}
});
});
});
</script>
<form id="myform" class="form_statusinput">
<input type="hidden" name="toid" id="toid" value="<?php echo $user1_id ?>">
<input class="input" name="newmsg" id="newmsg" placeholder="Say something" autocomplete="off">
<div id="button_block">
<input type="submit" id="button" value="Feed" >
</div>
</form>
Unless you are omitting some of your code, the problem is this line:
homestatus()
You never defined this function, so the submit throws an error.
You may want to take a look at jQuery (www.jquery.com) or another js framework.
Such frameworks do most of the stuff you normally have to do by hand.
There are also a bunch of nice helper functions for sending form data or modifying html elements
First let me say I'm new to Ajax. I've been reading articles from jquery.com and some tutorials but I didn't figured it out yet how this works on what I'm trying to achieve.
I am trying to get the weather for a searched city using Google's Weather API XML, without page refresh.
I managed to retrieve the Weather XML and parse the data but everytime I search for a different place, the page reloads since my weather widget is under a tab.
This is what I have in my HTML:
<script type="text/javascript">
$(document).ready(function(){
// FOR THE TAB
$('.tab_btn').live('click', function (e) {
$('.tab_content').fadeIn();
});
$(".submit").click(function(){
$.ajax({
type : 'post',
url:"weather.php",
datatype: "text",
aysnc:false,
success:function(result){
$(".wedata").html(result);
}});
});
});
</script>
<style>.tab_content{display:none;}</style>
</head><body>
<input type="button" value="Show Content" class="tab_btn">
<div class="tab_content">
<h2>Weather</h2>
<form id="searchform" onKeyPress="return submitenter(this,event)" method="get"/>
<input type="search" placeholder="City" name="city">
<input type="hidden" placeholder="Language" name="lang">
<input type="submit" value="search" class="submit" style="width:100px">
</form>
<div id="weather" class="wedata">
</div>
</div>
And here is the actual demo I'm working on: http://downloadlive.org.
Now, if I add action="weather.php" on the search form I get the results, but I get redirected to weather.php which is logical. Without the action="weather.php", everytime I search my index which I'm on, adds up /?city=CITY+NAME which shouldn't. This should be added to weather.php, get the results and then retrieve them back into my index, if that makes sense?
This is my php code for weather.php: http://pastebin.com/aidXCeQg
which can be viewed here: http://downloadlive.org/weather.php
Can someone please help me out with this please?
Thanks alot
You just need to return false; from the click event handler. This will prevent the default action from occuring - in this case, submitting the form. Also, remove the async: false setting. You almost never want synchronous ajax requests.
$(".submit").click(function(){
$.ajax({
type : 'post',
url:"weather.php",
datatype: "text",
success: function(result){
$(".wedata").html(result);
}
});
return false;
});
Alternately you can pass a parameter name to the callback and then use event.preventDefault() to accomplish the same result as above:
$(".submit").click(function(e){
$.ajax({
type : 'post',
url:"weather.php",
datatype: "text",
success: function(result){
$(".wedata").html(result);
}
});
e.preventDefault();
});
You need to send the form data with the POST. It's super-easy to do this using .serialize().
$(".submit").click(function(){
$.ajax({
type : 'post',
url:"weather.php",
data: $(this.form).serialize(),
datatype: "text",
success: function(result){
$(".wedata").html(result);
}
});
return false;
});
im trying to achieve the following, in php i have a form like this:
<form method="post" id="form_1" action="php.php">
<input type="submit" value="add" name="sub"/>
<input type="submit" value="envoi" name="sub"/>
</form>
the form action file is:
<?php
if( $_POST["sub"]=="add"){ ?>
<script>
alert("")
</script>
<?php echo "ZZZZZZ"; ?>
<?php } ?>
so this means if i press sub with value add an alert prompt will come up, how can i do the same thing(differentiate both submit) but using a Ajax request:
the following code so does not work:
$(function(){
$('form#form_1').submit(function(){
var _data= $(this).serialize()
$.ajax({
type: 'POST',
url: "php.php?",
data:_data,
success: function(html){
$('div#1').html(html)
}
})
})
})
</script>
</head>
<body>
<div id="1" style="width: 100px;height: 100px;border: 1px solid red"></div>
<form method="post" id="form_1" action="javascript:;">
<input type="submit" value="add" name="sub"/>
<input type="submit" value="envoi" name="sub"/>
</form>
</body>
You could put the event handler on the buttons instead of on the form. Get the parameters from the form, and then add a parameter for the button, and post the form. Make sure the handler returns "false".
$(function() {
$('input[name=sub]').click(function(){
var _data= $('#form_1').serialize() + '&sub=' + $(this).val();
$.ajax({
type: 'POST',
url: "php.php?",
data:_data,
success: function(html){
$('div#1').html(html);
}
});
return false;
});
});
You have to explicitly add the "sub" parameter because jQuery doesn't include those when you call "serialize()".
In this case you need to manually add the submit button to the posted data, like this:
$(function(){
$('form#form_1 :submit').submit(function(){
var _data = $(this).closest('form').serializeArray(); //serialize form
_data.push({ name : this.name, value: this.value }); //add this name/value
_data = $.param(_data); //convert to string
$.ajax({
type: 'POST',
url: "php.php?",
data: _data,
success: function(html){
$('div#1').html(html);
}
});
return false; //prevent default submit
});
});
We're using .serializeArray() to get a serialized version of the form (which is what .serialize() uses internally), adding our name/value pair to that array before it gets serialized to a string via $.param().
The last addition is a return false to prevent the default submit behavior which would leave the page.
Lots of semicolon missing, see below
$(function(){
$('form#form_1').submit(function(){
var _data= $(this).serialize();
$.ajax({
type: 'POST',
url: "php.php?",
data:_data,
success: function(html){
$('div#1').html(html);
}
});
});
});
jQuery Form plugin provide some advance functionalities and it has automated some tasks which we have to do manually, please have a look at it. Also it provides better way of handling form elements, serialization and you can plug pre processing functions before submitting the form.
