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

Warning: Invalid argument supplied for foreach() in C:wampwwwsubmit_order.php on line 42

My HTML form code-

<input disabled="disabled" class="input_text" onkeyup="JAVASCRIPT:check_row();" name="qty[]" type="text" id="qty_field1" size="6">

My current ajax send params-

var params="qty="+document.table_form.elements["qty[]"]";

My PHP array fetch -

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

Jquery Ajax - Post Array From Javascript ?

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?

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?

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?

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

The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. 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.

<script type="text/javascript">
$(document).ready(function() {
var options = {

CodeIgniter: Getting Data From Form Array Into Post Array?

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?

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.

Send HTTP Post With Array?

I'm trying to use this nice function:

function do_post_request($url, $data, $optional_headers = null) {
$params = array('http' => array(
'method' => 'POST',
'content' => $data
if ($optional_headers !== null) {
$params['http']['header'] = $optional_headers;

to send a POST command to a specific url, my problem is i'm trying to send the post paramters in a form of an array, something like this

login[username]: myusername
login[password]: mypassword,

however i'm not able to do that, calling the function with :

$login_post = array('login[username]' => $email,
'login[password]' => '');
do_post_request(getHost($website['code']), $login_post);

always send the data to the post in the form:

username: myusername

Javascript Array Created From Ajax Request

I am trying to populate an array (for use with jquery-ui element) using an Ajax request which I am not very familiar with. There are two files, selectStudents.php which is what will be viewed and loadStudents.php which is what the Ajax requests. When I view loadStudents.php, copy the output, and replace the Ajax request with that instead it works perfect, so I am simply doing something wrong with my ajax.

Send JavaScript Array To Script Using GET?

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?

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.

Javascript - JS Ajax - Displaying Page As It Loops Through Array

However, the current way I have the JS written, it only displays the video_feed_ajax.php when its completley loaded (when its looped through the entire array). ->Is there a way to display the video_feed_ajax.php each time it goes through the loop, so the videos are shown as it loops through instead of just at the end?

The portions of my JS that apply:
