Submit form without page reloading

Question

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...

Answer 1

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>

Answer 2

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.

Answer 3

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

Answer 4

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;
}

Answer 5

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

<?php
$Submit = isset($_POST['Submit']) ? $_POST['Submit'] : false;
$Name = isset($_POST['Name']) ? $_POST['Name'] : '';
if($Submit){
 echo $Name;
}
?>

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:

<?php 
$name = isset($_POST['name']) ? $_POST['name'] : '';
$descr = isset($_POST['descr']) ? $_POST['descr'] : '';


echo $name;
echo $descr;

?>

server_action.php

 <?php $name = isset($_POST['name']) ? $_POST['name'] : ''; $descr = isset($_POST['descr']) ? $_POST['descr'] : ''; echo $name; echo $descr; ?>

Answer 6

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(){...},
    });
}

Answer 7

This should solve your problem.
In this code after submit button click we call jquery ajax and we pass url to post
type 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>

Answer 8

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>
  ');
}

Answer 9

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.

Answer 10

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.

Answer 11

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 .

Answer 12

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>

Answer 13

如果您不想使用 javascript，页面将重新加载

Answer 14

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.

Answer 15

如果您提交到表单所在的同一页面，您可以编写表单标签而无需操作，它会提交，如下所示

<form method='post'> <!-- you can see there is no action here-->

Answer 16

A further possibility is to make a direct javascript link to your function:

<form action="javascript:your_function();" method="post">

...

Answer 17

I don't know JavaScript and I just started to learn PHP, so what helped for me from all those responses was:

1. 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>

2. 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;
    }
    ?>

3. 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 :)

Answer 18

For anyone using just Javascript, you can try this:

<form action="" method="get" onsubmit="yourFunction(event); return false;">

And in yourFunction() , you can use preventDefault.

function yourFunction(event) {
    event.preventDefault();
    //other logic...
}

Answer 19

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;
});
