Javascript - Send A Form Array Using AJAX As A POST Array?

Jun 21, 2011

I am looking for a way to send my html form array to the php script to execute as an array.I tried several methods but nothing worked for me. My php array works well with normal submit but with ajax it says

foreach($_POST['qty'] as $value){


Jquery Ajax - Post Array From Javascript ?

Aug 27, 2010

I want to post an array using Jquery Ajax to php. Is this possible ?

I tried following :

type: "POST",
url: "path",
data: "styles=" + strstyles + "&templateId=" + custTempId, //strstyles is an associative array
dataType: "json",
success: function (data) { .....}

but, styles hold no data. I spent a lot of time, before adding data type to the declaration. What can be the reason for "styles" being posted as null ?

I want to post style sheet dom object and save the class names and properties to DB. With the above edit, adding datatype did not help. I think it is b'coz the string is not in json format as follows -


As the my string has double quotes, it is not following the format, and I think that's the reason, I'm getting an empty array. How can I handle this ?

Javascript - Create An Associate Array In Jquery And Send It Via Ajax?

Aug 17, 2010

How would I make an associative array (or some comparable alternative) in jQuery AND send that array via ajax to a php page so that I can use php to handle it?

// jQuery
if($something == true) {
data[alt] = $(this).attr('alt');


Then, send this array using the .ajax() function

// jQuery
data: /* somehow send my array here */,


I've done a little googling on the subject and have read that you cannot make an associative array with javascript so I'm really just looking for some alternative.

Send An Array Of Javascript Object To A Script Via $.post?

Sep 30, 2009

I have a table of data on my page. The columns are "start", "end", "comment", and "options". Within the options column is a button to delete the row, and a button that makes a row of the table editable. This allows the values of "start", "end", and "comment" to be changed. Clicking it again finishes the editing process. Finally, there is a way to add another row to the table. All of this works as expected.

I want to add a button at the bottom that creates an array out of the data in the table, that looks like this (represented as JSON purely for ease of showing to SO: not required):

"comment":"an example date.",


I shouldn't have too much trouble building the array, but once I have, how can I post it to a backend php script (which will then use put_csv() to write the data to a file)? Ideally, it would be availiable server-side in a array format, to allow validation.

Javascript - Calling Script With Ajax And JQuery / Send It POST, Not GET So The User Can't See The Variables In Address Bar?

Aug 13, 2010

Right now I have this:

echo "<a href='misc/removeWallComment.php?id=" .
$displayWall['id'] . "&uID" . $displayWall['uID'] . "&BuID" .
$displayWall['BuID'] . "' title='ta bort inlägg'>
<span class='removeWallComment'></span> </a>";

Its an icon with a link that removes the comment when you click.

Now, it goes to misc/removeWallComment.php and echo out "comment removed". But I would like to integrate it with my current site, so you don't go to another page to delete the commehnt. With this I thought of using an ajax call to removeWallComment.php.

Now as you see on the link it requires three variables, id, uID and BuID, and I want to send it POST, not GET so the user can't see the variables in address bar. On success it should just alert ok.

How can I do this?

Javascript - Ajax / It - Contact Form Not Able To Send Mail

I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful.

CodeIgniter: Getting Data From Form Array Into Post Array?

Nov 6, 2010

I'm racking my brain. I'm using CodeIgniter, trying to get a value from a form checkbox into a data array to send off to the database. Here are the snippets:

Form (view):

<label>Rental Car?</label><input type="checkbox" name="options[is_rental]" value="1" <?php echo set_checkbox('options[is_rental]', '1', FALSE); ?> />


$data['is_rental'] = $this->input->post('options[is_rental]');

Now, during this process I'm also validating and re-populating the form with data using options[is_rental] and that works just fine. Using var_dump I get:

Dumps (with the checkbox checked) from the controller:







array(3) { ["engine"]=> string(4) "4cyl" ["transmission"]=> string(9) "automatic" ["is_rental"]=> string(1) "1" }

For what it's worth, I can't get to those other values in the array either.

Json MultiDimensional Array For Ajax Post?

Feb 3, 2011

it is possible to serialize HTML fields which are in a multi-dimensional array format for transmission over AJAX post?

Tried serializeArray and that formats 1 level of the array.

Data I need to serialize would be a series of name/value fields e.g.

name="customer" value="the value"
name="location" value="the location"

Using serializeArray() works fine on these e.g.

var formData = $('#createVacancy :input');
var serializedFormData = formData.serializeArray();

But some of the form data uses HTML array notation e.g.

name="tier[1][tiers][5][groupId]" value="5"
Result from serializeArray()

Normal name/value pairs comes through like Object { name="customer_name", value="Test customer name"}

But fields which use html array notation come through like:

Object { name="tier[1][publication_date]", value="03 Feb 2011"},
Object { name="tier[1][publication_date_db]", value="2011-02-03"},
Object { name="tier[1][tiers][5][groupId]", value="5"},
Object { name="tier[1][tiers][5][groupName]", value="Diamond"}

I'd have though this would need to be broken down into further objects.

Javascript Array Created From Ajax Request

There are two files, selectStudents.php which is what will be viewed and loadStudents.php which is what the Ajax requests.

Send JavaScript Array To Script Using GET?

Jul 20, 2009

I have an interactive web application powered by jQuery where users can manipulate visual objects on the screen. When done, the "state" of JavaScript objects should be sent to PHP to store into database. I'd prefer to use GET for this, but solution that uses POST to submit the data is also viable.

I'm currently thinking to serialize all JS objects using something like base64 encoding and just use something like:

var str = encode_objects();
document.location = 'result.php?result='+str;

However, something tells me there has to be some, more elegant, way than writing my own base64 encoding function in JavaScript. Isn't there something already built into JavaScript that can do the job?

Update: decoding in PHP is not the problem. I know how to decode base64, JSON, whatever in PHP. The problem is how to encode data on JavaScript side.

AJAX is out of the question. It has to be a clean GET or POST with page reload.

Send JavaScript Array Using JSON Or XML?

Apr 19, 2009

I need to send the contents of a JavaScript array to server where a PHP script will persist individual array entries in a MYSQL database. I am NOT using jQuery but I am about to integrate Prototype framework into my project.

I gather that the JS array can easily be converted to JSON using the toJSON() method provided by Prototype. I could then POST this to my script which would somehow de-JSONise the array and insert the values into DB.

But what I am also interested in is NOT using JSON data-interchange format, but converting the JS array into XML, which can be very easily parsed by the simplexml PHP extension (save myself some development time server-side). My question(s) are thus: should I go for JSON or XML? and How could I turn the JS array into XML? (is there a toXML() method like there is toJSON() in Prototype?)

I am aware of the great variety of very similar questions, but they all seem to ask this question the other way around... converting JSON to JS arrays, and many are jQuery related. So please help me, even if this is potentially a duplicate and you may have answered this some place else.

Return Multi Dimension Array To Javascript / AJAX

Jun 7, 2010

My understanding is that in order to return a complex PHP variable to Javascript, it should be done via AJAX and json_encode. Could somebody give me an actual example (both PHP and Javascript code) of this? Lets say we have the two-dim array in PHP:

$twoDArr = array( array('Greg', 44, 'Owner'),
array('Joe', 23, 'Renter'),
array('Susan', 39, 'Owner'),
array('John', 32, 'Renter)

How would we return this to an analogous two dimensional array in javascript using json_encode?

Codeigniter - Form Validation Converting Post Variables From Array To "Array" String

Sep 5, 2010

I am building an HTML form with a set of checkboxes for selecting multiple categories using this format:

<input type="checkbox" name="category[]" />

So, when I post and print_r($_POST) to view the variable and values I get:

[27] => on
[28] => on
[29] => on

Once I run $this->form_validation->run(); the categories array becomes "Array" as a string. I believe I have narrowed it down to "prep_for_form" function in the system/libraries/Form_validation.php file, but it seems like the recursive function is working correctly.

Javascript - Return Array To Jquery Ajax And Populating A List / With Some If()'s?

May 19, 2011

Trying to make an ajax driven, sortable contact list.A menu with 3 alternatives should upon click render a new list with updated data.

Been searching around a bit but havn't found any good info on this (as from what I understand atleast..)

This is what populates my list at the moment. I know, bad choice of variables..

$checkedin='Check Out';
$checkedin='Check In';
<li id="<?php print $c['id']; ?>" class="clearfix gradient1 <?php print $checked; ?>">
<?php print $c['name']; ?>
<img src="options.png" class="options rounded3" alt="options" width="16" height="16" />
<?php if($c['ischeckedin']): ?>
class="button checkerout"
value="<?php print $checkedin; ?>"
name="<?php print $c['id']; ?>" />
<?php else: ?>
class="button checkerin"
value="<?php print $checkedin; ?>"
name="<?php print $c['id']; ?>" />
<?php endif; ?>
<?php endforeach; ?>

So basicly it's a list of contacts. Some are checked in, therefore the different classes and buttons. (Any cleaner suggestions are more than welcome!)

But now I need to populate the list via Ajax, since I need to be able to sort it. So I send some more data along with the call and my php/mysql returns some filtered data.

<li> -
ID should be the id from the db.class needs to differ between 'checkedin' and '' depending on result from mysql.

<input> -
class should be 'checkerin' or 'checkerout' depending on result from should be the id from the db

The problem, what do I do with the returned data from php -> ajax -> print?

And how do I translate all those nasty if()'s so that I can make difference amongst checked and nonchecked contacts? Edit it before returning it?

Javascript - Associative Array Solution To Work With JQuery AJAX?

$(document).ready( function() {
var i = 1;
type: 'POST',

data: 'id=' + i,


But I want to display some data, related with the numbers in array, say some names, name1 to name20 with respect to array elements. In my page, the table cells having class="title" get populated with array elements (here image names). But i want class="title" filled with names 1-20, which should be delivered along with array elements like an associative array. I think Associative array will be the best option.

How can I do this using Javascript and jQuery?? Note:- Don't worry about PHP. If somebody suggest a specific format to echo data in PHP, I can make it out. I am a beginner..

Now the problem comes here: when a song in a playlist is finished, I'd like to refresh the page and send incremented itemId via post request, so the server side will know which song I'm currently listening to.

Post Form Fields Into Array - 'group' Each Form Field

Apr 14, 2010

A user can choose a number between 1 and 10 from a list box. Based on the value of their choice I display the same form 1 - 10 times on the page and this form is there to collect personal data. Each form will have a small number of text fields and also some checkboxes e.g:

name (text)
dob (text)
option 1 (checkbox)
option 2 (checkbox)
option 3 (checkbox)

(note the checkboxes should be grouped as an array as they are dynamically built) My question is, how do I 'group' each form field so that when the page is posted (saved) I can capture the correct data for each form filled in? I know arrays are involved somewhere here but not sure how it is implemented.
