I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form...
So anybody who wants can send a tip of the ad to some friends email-adress.
I am guessing the form must be submitted to a php page right?
<form name="tip" method="post" action="tip.php">
Tip somebody:
<input
name="tip_email"
type="text"
size="30"
onfocus="tip_div(1);"
onblur="tip_div(2);"
/>
<input type="submit" value="Skicka Tips" />
<input type="hidden" name="ad_id" />
</form>
When submitting the form, the page gets reloaded... I don't want that...
Is there any way to make it not reload and still send the mail?
Preferrably without ajax or jquery...
I've found what I think is an easier way.
If you put an Iframe in the page, you can redirect the exit of the action there and make it show up.
You can do nothing, of course. In that case, you can set the iframe display to none.
<iframe name="votar" style="display:none;"></iframe>
<form action="tip.php" method="post" target="votar">
<input type="submit" value="Skicka Tips">
<input type="hidden" name="ad_id" value="2">
</form>
You'll need to submit an ajax request to send the email without reloading the page. Take a look at http://api.jquery.com/jQuery.ajax/
Your code should be something along the lines of:
$('#submit').click(function() {
$.ajax({
url: 'send_email.php',
type: 'POST',
data: {
email: 'email#example.com',
message: 'hello world!'
},
success: function(msg) {
alert('Email Sent');
}
});
});
The form will submit in the background to the send_email.php page which will need to handle the request and send the email.
You either use AJAX or you
create and append an iframe to the document
set the iframes name to 'foo'
set the forms target to 'foo'
submit
have the forms action render javascript with 'parent.notify(...)' to give feedback
optionally you can remove the iframe
Fastest and easiest way is to use an iframe.
Put a frame at the bottom of your page.
<iframe name="frame"></iframe>
And in your form do this.
<form target="frame">
</form>
and to make the frame invisible in your css.
iframe{
display: none;
}
SUBMITTING THE FORM WITHOUT RELOADING THE PAGE AND GET THE RESULT OF SUBMITTED DATA ON THE SAME PAGE.
Here's some of the code I found on the internet that solves this problem :
1.) IFRAME
When the form is submitted, The action will be executed and target the specific iframe to reload.
index.php
<iframe name="content" style="">
</iframe>
<form action="iframe_content.php" method="post" target="content">
<input type="text" name="Name" value="">
<input type="submit" name="Submit" value="Submit">
</form>
iframe_content.php
<?php
$Submit = isset($_POST['Submit']) ? $_POST['Submit'] : false;
$Name = isset($_POST['Name']) ? $_POST['Name'] : '';
if($Submit){
echo $Name;
}
?>
2.) AJAX
Index.php:
<form >
<input type="" name="name" id="name">
<input type="" name="descr" id="descr">
<input type="submit" name="" value="submit" onclick="return clickButton();">
</form>
<p id="msg"></p>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">
function clickButton(){
var name=document.getElementById('name').value;
var descr=document.getElementById('descr').value;
$.ajax({
type:"post",
url:"server_action.php",
data:
{
'name' :name,
'descr' :descr
},
cache:false,
success: function (html)
{
alert('Data Send');
$('#msg').html(html);
}
});
return false;
}
</script>
server_action.php
<?php
$name = isset($_POST['name']) ? $_POST['name'] : '';
$descr = isset($_POST['descr']) ? $_POST['descr'] : '';
echo $name;
echo $descr;
?>

A further possibility is to make a direct javascript link to your function:
<form action="javascript:your_function();" method="post">
...
It's a must to take help of jquery-ajax in this case. Without ajax, there is currently no solution.
First, call a JavaScript function when the form is submitted. Just set onsubmit="func()". Even if the function is called, the default action of the submission would be performed. If it is performed there would be no way of stoping the page from refreshing or redirecting. So, next task is to prevent the default action. Insert the following line at the start of func().
event.preventDefault()
Now, there will be no redirecting or refreshing. So, you simply make an ajax call from func() and do whatever you want to do when call ends.
Example:
Form:
<form id="form-id" onsubmit="func()">
<input id="input-id" type="text">
</form>
Javascript:
function func(){
event.preventDefault();
var newValue = $('#input-field-id').val();
$.ajax({
type: 'POST',
url: '...',
data: {...},
datatype: 'JSON',
success: function(data){...},
error: function(){...},
});
}
this is exactly how it CAN work without jQuery and AJAX and it's working very well using a simple iFrame. I LOVE IT, works in Opera10, FF3 and IE6. Thanks to some of the above posters pointing me the right direction, that's the only reason I am posting here:
<select name="aAddToPage[65654]"
onchange="
if (bCanAddMore) {
addToPage(65654,this);
}
else {
alert('Could not add another, wait until previous is added.');
this.options[0].selected = true;
};
" />
<option value="">Add to page..</option>
[more options with values here]</select>
<script type="text/javascript">
function addToPage(iProduct, oSelect){
iPage = oSelect.options[oSelect.selectedIndex].value;
if (iPage != "") {
bCanAddMore = false;
window.hiddenFrame.document.formFrame.iProduct.value = iProduct;
window.hiddenFrame.document.formFrame.iAddToPage.value = iPage;
window.hiddenFrame.document.formFrame.submit();
}
}
var bCanAddMore = true;</script>
<iframe name="hiddenFrame" style="display:none;" src="frame.php?p=addProductToPage" onload="bCanAddMore = true;"></iframe>
the php code generating the page that is being called above:
if( $_GET['p'] == 'addProductToPage' ){ // hidden form processing
if(!empty($_POST['iAddToPage'])) {
//.. do something with it..
}
print('
<html>
<body>
<form name="formFrame" id="formFrameId" style="display:none;" method="POST" action="frame.php?p=addProductToPage" >
<input type="hidden" name="iProduct" value="" />
<input type="hidden" name="iAddToPage" value="" />
</form>
</body>
</html>
');
}
This should solve your problem.In this code after submit button click we call jquery ajax and we pass url to posttype POST/GET
data: data information you can select input fields or any other.
sucess: callback if everything is ok from server
function parameter text, html or json, response from server
in sucess you can write write warnings if data you got is in some kind of state and so on. or execute your code what to do next.
<form id='tip'>
Tip somebody: <input name="tip_email" id="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/>
<input type="submit" id="submit" value="Skicka Tips"/>
<input type="hidden" id="ad_id" name="ad_id" />
</form>
<script>
$( "#tip" ).submit(function( e ) {
e.preventDefault();
$.ajax({
url: tip.php,
type:'POST',
data:
{
tip_email: $('#tip_email').val(),
ad_id: $('#ad_id').val()
},
success: function(msg)
{
alert('Email Sent');
}
});
});
</script>
You can try setting the target attribute of your form to a hidden iframe, so the page containing the form won't get reloaded.
I tried it with file uploads (which we know can't be done via AJAX), and it worked beautifully.
Have you tried using an iFrame? No ajax, and the original page will not load.
You can display the submit form as a separate page inside the iframe, and when it gets submitted the outer/container page will not reload. This solution will not make use of any kind of ajax.
function Foo(){
event.preventDefault();
$.ajax( {
url:"<?php echo base_url();?>Controllername/ctlr_function",
type:"POST",
data:'email='+$("#email").val(),
success:function(msg) {
alert('You are subscribed');
}
} );
}
I tried many times for a good solution and answer by #taufique helped me to arrive at this answer.
NB : Don't forget to put event.preventDefault(); at the beginning of the body of the function .
I did something similar to the jquery above, but I needed to reset my form data and graphic attachment canvases.
So here is what I came up with:
<script>
$(document).ready(function(){
$("#text_only_radio_button_id").click(function(){
$("#single_pic_div").hide();
$("#multi_pic_div").hide();
});
$("#pic_radio_button_id").click(function(){
$("#single_pic_div").show();
$("#multi_pic_div").hide();
});
$("#gallery_radio_button_id").click(function(){
$("#single_pic_div").hide();
$("#multi_pic_div").show();
});
$("#my_Submit_button_ID").click(function() {
$("#single_pic_div").hide();
$("#multi_pic_div").hide();
var url = "script_the_form_gets_posted_to.php";
$.ajax({
type: "POST",
url: url,
data: $("#html_form_id").serialize(),
success: function(){
document.getElementById("html_form_id").reset();
var canvas=document.getElementById("canvas");
var canvasA=document.getElementById("canvasA");
var canvasB=document.getElementById("canvasB");
var canvasC=document.getElementById("canvasC");
var canvasD=document.getElementById("canvasD");
var ctx=canvas.getContext("2d");
var ctxA=canvasA.getContext("2d");
var ctxB=canvasB.getContext("2d");
var ctxC=canvasC.getContext("2d");
var ctxD=canvasD.getContext("2d");
ctx.clearRect(0, 0,480,480);
ctxA.clearRect(0, 0,480,480);
ctxB.clearRect(0, 0,480,480);
ctxC.clearRect(0, 0,480,480);
ctxD.clearRect(0, 0,480,480);
} });
return false;
}); });
</script>
That works well for me, for your application of just an html form, we can simplify this jquery code like this:
<script>
$(document).ready(function(){
$("#my_Submit_button_ID").click(function() {
var url = "script_the_form_gets_posted_to.php";
$.ajax({
type: "POST",
url: url,
data: $("#html_form_id").serialize(),
success: function(){
document.getElementById("html_form_id").reset();
} });
return false;
}); });
</script>
I don't know JavaScript and I just started to learn PHP, so what helped for me from all those responses was:
Create inedx.php and insert:
<iframe name="email" style=""></iframe>
<form action="email.php" method="post" target="email">
<input type="email" name="email" >
<input type="submit" name="Submit" value="Submit">
</form>
Create email.php and insert this code to check if you are getting the data (you should see it on index.php in the iframe):
<?php
if (isset($_POST['Submit'])){
$email = $_POST['email'];
echo $email;
}
?>
If everything is ok, change the code on email.php to:
<?php
if (isset($_POST['Submit'])){
$to = $_POST['email'];
$subject = "Test email";
$message = "Test message";
$headers = "From: test#test.com \r\n";
$headers .= "Reply-To: test#test.com \r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
mail($to, $subject, $message, $headers);
}
?>
Hope this helps for all other rookies like me :)
Modern Answer without XHR or jQuery
It's 2022, we don't need to use old tools like XHR or jQuery when we have the Fetch API and the FormData API!
The first thing we need to do is prevent the default form submission behavior from occurring with event.preventDefault():
form.addEventListener("submit", function(event){
event.preventDefault();
// ...
});
Now we need to replace the submission behavior with our own AJAX request. The Fetch API makes it pretty simple to post form data - just create a new FormData object, populating it with the form's values, and use it as the body of a fetch request:
fetch(form.action, {
method: "post",
body: new URLSearchParams(new FormData(form))
});
Note that this submits an HTTP request using the multipart/form-data format. If you need to post the data using application/x-www-form-urlencoded, create a new URLSearchParams object from the FormData object and use that as the fetch's body.
fetch(form.action, {
method: "post",
body: new URLSearchParams(new FormData(form))
});
Here's a full code example:
let form = document.querySelector("form");
form.addEventListener("submit", function(event){
event.preventDefault();
fetch(form.action, {
method: "post",
body: //new FormData(form) // for multipart/form-data
new URLSearchParams(new FormData(form)) //for application/x-www-form-urlencoded
});
});
<form method="POST">
<input name="name" placeholder="Name" />
<input name="phone" type="tel" placeholder="Phone" />
<input name="email" type="email" placeholder="Email" />
<input name="submit" type="submit" />
</form>
The page will get reloaded if you don't want to use javascript
You will need to use JavaScript without resulting to an iframe (ugly approach).
You can do it in JavaScript; using jQuery will make it painless.
I suggest you check out AJAX and Posting.
if you're submitting to the same page where the form is you could write the form tags with out an action and it will submit, like this
<form method='post'> <!-- you can see there is no action here-->
Here is some jQuery for posting to a php page and getting html back:
$('form').submit(function() {
$.post('tip.php', function(html) {
// do what you need in your success callback
}
return false;
});

The page will get reloaded if you don't want to use javascript
You will need to use JavaScript without resulting to an iframe (ugly approach).
You can do it in JavaScript; using jQuery will make it painless.
I suggest you check out AJAX and Posting.
if you're submitting to the same page where the form is you could write the form tags with out an action and it will submit, like this
<form method='post'> <!-- you can see there is no action here-->
Here is some jQuery for posting to a php page and getting html back:
$('form').submit(function() {
$.post('tip.php', function(html) {
// do what you need in your success callback
}
return false;
});
I've been having this issue for a while now and I guess I'm stuck. I've been reading on how to use AJAX to send data to a PHP file.
The thing is, I don't really get how to take the value of a radio button in a HTML page and then send that value through AJAX to a PHP file which will then process that value.
So for example:
If I had 2 radio buttons
<input type="radio" name="radio" value="yes">
<input type="radio" name="radio" value="no">
And I would like to take the value of those radio buttons and send it to my PHP file using AJAX.
Next I would be able to process those values in PHP.
How would I make it so that AJAX sends the value of the selected radio button to PHP?
Thanks, in advance!
EDIT:
Full code:
HTML File
<script type="text/javascript">
function updatePremium() {
var input1= $("#premium-yes").val();
var input2= $("#premium-no").val();
$.post( "upd_premium.php", { input1: input1, input2: input2 } );
}
</script>
<div class="usersRow2">
<form action="" method="POST"><label>Premium:</label> <p class="text-info-premium"><?php echo ucwords($premium_check) ?><i class="icon-star"></i></p> <div class="controls-premium"><i class="fa fa-pencil"></i> Edit</div></form>
</div>
<script>
$('#edit-premium').click(function() {
var text = $('.text-info-premium').text();
var input = $('<input type="radio" name="premium" id="premium-yes" value="yes">Yes <input type="radio" name="premium" id="premium-no" value="no">No <div id="premium"></div>')
$('.text-info-premium').text('').append(input);
$('#edit-premium').remove();
$('Update').insertAfter('#premium');
$('<i class="fa fa-times" title="Cancel Edit"></i> <br /><br /><br />').insertAfter('#update-premium');
$('.fa-times').click(function() {
location.reload();
});
});
</script>
PHP File
if($_POST['input1'] == 'yes') {
print_r($_POST);
}
Use jQuery. From the docs, a post is easy:
$.post( "test.php", { name: "John", time: "2pm" } );
Now, you need to get the values of the inputs and pass them to the post:
<input type="radio" name="radio" value="yes" id="input1">
<input type="radio" name="radio" value="no" id="input2">
<script>
var input1= $( "#input1" ).val();
var input2= $( "#input2" ).val();
$.post( "yourphpfile.php", { input1: input1, input2: input2 } );
</script>
I'm trying to pass javascript array to php using ajax and jQuery.
I have simple page that contains a series of numbers that I've made selectable via jQuery UI (see below) When I select a group of numbers, I use array.push to add those numbers to an array called "shift". Here's the question: What's the simplest way to send this array to PHP? Will it remain an array after it comes over? I'm new to coding and would appreciate any help I can get. After a lot of research, here's what I've tried. Oh, I've managed to figure out how to submit the form to PHP, it's the jQuery UI array that i'm stuck on.
here's my main.php
<!DOCTYPE html>
<html>
<head>
<title>test</title>
<link rel="stylesheet" type="text/css" href="main.css">
</head>
<body>
<div class = "container">
<form action="post.php" method="post" id="add">
<input type="text" class="leader" name="name" placeholder="Leader">
<input type="text" class="date" name="date" placeholder="date">
<input type="text" class="time" name="time" placeholder="time">
<input type="text" class="score" name="score" placeholder="score">
<input type="submit" id="btn" value="send" />
</form>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<script type="text/javascript" src="jquery-ui-1.10.4.custom.js"></script>
<script src="globe.js"></script>
<ul id ="hours_zoned">
<li class="nine">9</li>
<li class="ten">10</li>
<li class="eleven">11</li>
<li class="twelve">12</li>
<li class="one">1</li>
<li class="two">2</li>
<li class="three">3</li>
<li class="four">4</li>
<li class="five">5</li>
<li class="six">6</li>
<li class="seven">7</li>
<li class="eight">8</li>
<li class="nine">9</li>
</ul>
</div>
</body>
</html>
here's my post.php
<html>
<body>
/* I'm using all of these echoes to verify that the data is coming
over. Only "shift" fails to come over */
NAME <?php echo $_POST["name"]; ?><br>
DATE <?php echo $_POST["date"]; ?><br>
TIME <?php echo $_POST["time"]; ?><br>
SCORE: <?php echo $_POST["score"]; ?><br>
SHIFT: <?php echo $_POST["shift"]; ?>
<?php
include("db.php");
$name = $_POST["name"];
$date = $_POST["date"];
$time = $_POST["time"];
$query = "INSERT INTO leaders (name, shift_date, shift_time) VALUES ('$name', '$date', '$time')";
$result = $db->query($query);
?>
</body>
</html>
here is my globe.js
var shift = []; //create array to store zoned hours
$(function() {
$( "#hours_zoned" ).selectable();
$( "#hours_zoned" ).on('click', 'li', function() {
$(this).addClass("clicked ui-selected");
$( this ).css( "background-color", "#e74c3c" );
$( this ).selectable({ disabled: true });
var floorTime = $(this).text(); // get the value of the hour that was clicked
shift.push(floorTime); // add that hour to the floorTime
});
/*$('#add').on('submit', function() {
var name = $('.leader').val(); */
$('#btn').on('submit', function() {
$.ajax({
type: 'POST',
url: 'post.php',
data: shift,
success: function(msg) {
alert(msg);
}
});
});
return false;
});
You are only sending the key
data: shift,
according to the docs - Object must be Key/Value pairs. (https://api.jquery.com/jQuery.ajax/)
try
data: {shift: shift},
so it is now
$('#btn').on('submit', function() {
$.ajax({
type: 'POST',
url: 'post.php',
data: {shift: shift},
success: function(msg) {
alert(msg);
}
});
return false;
});
EDIT: Your ajax function was a bit jacked up. Fixed that for you also. See new code.
Your ajax submit isn't running. Add return false; to prevent the main form from submitting. I'm thinking the easiest way to add the array would be to insert it into a hidden input immediately after being pushed in your jQuery function. Then you would just serialize the form data and send it all in your ajax function. See below:
New form:
<form action="post.php" method="post" id="add">
<input type="text" class="leader" name="name" placeholder="Leader">
<input type="text" class="date" name="date" placeholder="date">
<input type="text" class="time" name="time" placeholder="time">
<input type="text" class="score" name="score" placeholder="score">
<input type="hidden" class="shift" name="shift">
<input type="submit" id="btn" value="send" />
</form>
New function:
var shift = []; //create array to store zoned hours
$(function() {
$( "#hours_zoned" ).selectable();
$( "#hours_zoned" ).on('click', 'li', function() {
$(this).addClass("clicked ui-selected");
$( this ).css( "background-color", "#e74c3c" );
$( this ).selectable({ disabled: true });
var floorTime = $(this).text(); // get the value of the hour that was clicked
shift.push(floorTime); // add that hour to the floorTime
$("#add .shift").val(shift); // add shift array to hidden input in form
});
/*$('#add').on('submit', function() {
var name = $('.leader').val(); */
$('#add').submit(function() {
$.ajax({
type: 'POST',
url: 'post.php',
data: $("#add").serialize(),
success: function(msg) {
alert(msg);
}
});
return false; // you need this to prevent the other form submission
});
return false;
});
Untested, but that should get you going in the right direction.
Just wanna add to the answers given here..
You also need to check if the items selected are in array already (prevent duplicate).. so to do that you can do it like this
*code is taken from Matt answer
if($.inArray(floorTime, shift) === -1) {
shift.push(floorTime);
$("#add .shift").val(shift);
}
Try parse_str().
$array = parse_str( $_POST['data'] );
I have formatted my form using uniform jquery plugin. Also for submitting the form i am using a link as i have added some effect to it and if I use input type submit for this it will get formatted with uniform .
<form>
<ul>
<li><label>Your Name:</label><input type="text" name="name" size="40"/></li>
<li><label>Your Email:</label><input type="email" name="email" size="40"/></li>
<li>
<label>Gender:</label>
<select name="gender">
<option>Male</option>
<option>Female</option>
</select>
</li>
<li><label>Subject:</label><input type="text" name="subject" size="40"/></li>
<li><label>Write your letter here:</label><textarea name="message" cols="60" rows="15"></textarea></li>
OR ELSE<br/><br/>
<li>
<label>Upload your letter:</label>
<input type="file" />
</li>
<li>
<a id="mylink" class="button" href="#">
<img src="button.png" alt="" />Send</a>
</li>
</ul>
</form>
Now i want to submit this form using the link and also want to email it to two email ids simultaneously. What javascript code can i use. I am using the following code to submit the form and then in send.php I am sending the mail.
a.onclick = function() {
$(this).parents('form:first').submit();
send.php;
return false;
}
Is it possible to call send.php like this?
Do you mean:
If you have action="send.php" in your form, then
$(document).ready(function() {
$("#mylink").click(function(e) {
e.preventDefault();
$(this).closest('form').submit();
});
});
Or, you can set action for the form and submit, like
$(document).ready(function() {
$("#mylink").click(function(e) {
e.preventDefault();
var myFrm = $(this).closest('form');
myFrm.get(0).setAttribute('action', 'send.php');
myFrm.submit();
});
});
OR, using ajax
$(document).ready(function() {
$("#mylink").click(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "send.php",
data: {your data to post here},
succes: function(resp) {
//your response here
}
});
});
});
Is it possible to call send.php like this?
Like this? No, you need to use ajax request:
$.ajax({
url :"send.php"
});
Extra tip: change:
$(this).parents('form:first').submit();
To:
$(this).closest('form').submit();
