edit - the info appears to be posting, but on form_data.php it doesn't seem to be retrieving the posted values
Here's the AJAX
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
$("#submit_boxes").submit(function() { return false; });
$('input[type=submit]').click(function() {
$.ajax({
type: 'POST',
url: 'form_data.php',
data: $(this).serialize(),
success: function(data) {
$('#view_inputs').html(data); //view_inputs contains a PHP generated table with data that is processed from the post. Is this doable or does it have to be javascript?
});
return false;
});
};
</script>
</head>
Here is the form I'm trying to submit
<form action="#" id = "submit_boxes">
<input type= "submit" name="submit_value"/>
<input type="textbox" name="new_input">
</form>
Here is the form_data page that gets the info posted to
<?php
if($_POST['new_input']){
echo "submitted";
$value = $_POST['new_input'];
$add_to_box = new dynamic_box();
array_push($add_to_box->box_values,$value);
print_r($add_to_box->box_values);
}
?>
Your form is submitting because you have errors which prevents the code that stops the form from submiting from running. Specifically dataType: dataType
and this.html(data)
. Firstly dataType
is undefined
, if you don't know what to set the data type to then leave it out. Secondly this
refers to the form element which has no html
method, you probably meant $(this).html(data)
although this is unlikely what you wanted, most likely its $(this).serialize()
you want. So your code should look like
$('form#submit_boxes').submit(function() {
$.ajax({
type: 'POST',
url: 'form_data.php',
data: $(this).serialize(),
success: success
})
return false;
});
Additionally if you have to debug ajax in a form submit handler the first thing you do is prevent the form from submitting(returning false can only be done at the end) so you can see what errors occurred.
$('form#submit_boxes').submit(function(event) {
event.preventDefault();
...
});
You can use jQuery's .serialize()
method to send form data
Some nice links below for you to understand that
jquery form.serialize and other parameters
One way to handle it...
Cancel the usual form submit:
$("#submit_boxes").submit(function() { return false; });
Then assign a click handler to your button:
$('input[type=submit]').click(function() {
$.ajax({
type: 'POST',
url: 'form_data.php',
data: this.html(data),
success: success,
dataType: dataType
})
return false;
});
