JQuery :: Array Of Checkboxes - Values Gets Duplicated When Posted Via Ajax Call

Dec 9, 2010

I have a very large form and have a couple of checkbox groups where multiple items can be selected. They are grouped as an array of checkboxes. When I post the checkbox groups, the PHP script receives duplicate values. If the group has 2 checkboxes, 4 values are posted. If it has 10 checkboxes, 20 values will be posted.

i.e:

I then submit everything to a PHP script via an Ajax call, then output the result to a div. (see below)

However, when my PHP script loops over the $_POST array, it seems that each checkbox array is duplicated, so my PHP array returns:

This happens with all my checkbox arrays, but not with an array of hidden fields for some reason.

I don't think this is a PHP problem, as it looped over everything correctly when submitting via a conventional POST. I checked the contents of $_POST, and it seems that the duplicates are being posted.

Ajax :: Unable To Get Posted Variables To Work

Apr 10, 2011

I am using ajax in my site and want to implement a friend request button. When a user clicks this button their userid and the userid of the friend thwey are requesting will go into a table called notifications in my mysql database. This works fine in regular html/php with javascript disabled but not when using javascript/ajax.

Here's my code which may clarify things:-

Code:

<script type="text/javascript">
function makeRequest(friendrequestloggedinuserid, friendrequestuserid)
{
if (window.XMLHttpRequest)

[Code]....

The above code works perfect if javascript is disabled and the button is clicked as the new row is inserted into the database however if javascript is enabled the alert shows inidicating the ajax file is working but the new row is not inserted. Is this something to do with the POST process between my javascript code and my ajax_processrequests.php file?

BTW $loggedinuserid and $userid are retrieved earlier on in my code but showing how they are retrieved is irrelevant to this because I know they are present at the point of the above code.

AJAX :: Passing Values As Array To Php File?

Aug 9, 2011

Over in this thread, someone suggested a solution to an issue I was having when attempting to send multiple values per select box to a php file. You can review my original post here for reference:

[URL]

The problem is, when I change my form names to be arrays (i.e. age[] vs. age), it broke my Ajax script. I copied the original script from w3schools, and I don't really know much about javascript/Ajax to know what it is that I need to do to fix this.

Here is my Ajax script:

Code:

<script type="text/javascript">
function showResult(name,age,gender,ethnicity,facility)
{
if (name=="" && age=="" && gender=="" && ethnicity=="" && facility=="")

[Code]....

Now, when I leave my field names without the [], the script works MAHvalously. However, as soon as I add in the [] to the field names, and also update the vars to be age[].value instead of age.value, etc, it breaks.

JQuery :: Listing Values Of Checked Checkboxes?

Apr 3, 2010

I am working on a form with a huge selection of checkboxes (certifications), arranged in a table (#certs). To make it easier for the user to check what certifications they have selected, I would like to add a list immediately following the #certs table that updates dynamically based on their selections.

I put a paragraph under the table with a span - ID certs_list. I was able to add to this with the following code, but if the checkbox is clicked multiple times, it keeps adding the same value over and over again. How can I simply add to the list (item 1, item 2, item 3) when a checkbox is checked and remove it if it is unchecked?

$

function
()

JQuery :: Validate -- Require Series Of Checkboxes When Named As Array[]?

Sep 23, 2009

I have a working example of jQuery validate working in the link below. The newsletter checkbox is required and working. However, the "colors" checkboxes are all named as an array ( ex: name="color[]" ), and so the problem lies in the validation code, where it uses the name of the element to require elements ( ex: newsletter: "required" ).

Code JavaScript:
<script>
$("#testform").validate({

Mar 20, 2006

i have a "on/off" toggle switch that hide and display a table row using javascript. On every click, this javascript will make use of AJAX to update the database on a table that stores the current state of the table row (whether to hide or display). Ok, basically it works on every page until i reach a page where only after "posting a form" will reach.

Getting Values From 40 Checkboxes

Jan 15, 2003

I am coding a quiz that will have 40 checkboxes that the user will be able to check.

(Right now I am trying to get this code to work with 4 and will change it to 40 once I figure out my problem.)

What I want to do is count up the amount of checked boxes and display it to the user.

I know I could do this with copying and pasting a line of code over and over again, but I thought it would be much smarter to use a loop and cut the JS down to only a few lines.

Adding Values Of Checkboxes?

Mar 14, 2010

I'm currently designing a website for a takeaway company, and have one page displaying their menu. So that customers can easily calculate how much their takeaway will cost, I'm going to put checkboxes next to each item.Each of the checkboxes' value will be the price of the item, and I need a script that will add the values (prices) of the checkboxes they've ticked.They can then see the total cost of their takeaway without having to work it out, and add or remove items accordingly. I will then add a button which will print out a list of the items they ticked with the total price at the bottom. The customer can bring this in with them and the staff can easily see what they want and how much to charge them.

Firstly, I need to know how to make Javascript add these values (and probably save them as a variable) Secondly, how would I make this display on the page (either after they click a button, or automatically so they can see the price real-time)? - I assume this would be basic coding --- document.write(var) And finally, how could I make a script which would print only the items which are ticked, and the total price?

How To Get Values From Checked / Unchecked Checkboxes

Jan 25, 2011

I have a for and lets say 4 checkboxes. I want to get the values of the checkboxes that are checked & to get the values of the checkboxes that are not checked. So if someone check the A & C checkbox I will get that A&C has this value (because they are checked!) and B,&D has this value(because they are not checked). Example this is my table....

JQuery :: Submit Multiple Checkboxes Via Ajax To PHP Script

Nov 24, 2009

I am working on improvements for a web app. It currently submits checkboxes to a php script for processing by simply submitting the form naturally. However I require this action using a ajax post to save bandwidth etc. and im struggling to work out how to do this. I am familiar with normal ajax posts using jquery but here I need to post an array.

Simplified a little this is what I have.
<input type="checkbox" name="ckdOrd[]" value="1" id="order_1" />
<input type="checkbox" name="ckdOrd[]" value="2" id="order_2" />
<input type="checkbox" name="ckdOrd[]" value="3" id="order_3" />
<input type="checkbox" name="ckdOrd[]" value="4" id="order_4" />

It used to build an array ckdOrd[] and post to a php script with a loop for processing. It needs to post the order numbers as an array for processing. Is there a way to simply create the same post using ajax jQuery?

The PHP simply does something like this
//get posted array
$ckdOrd=$_REQUEST['ckdOrd'];
foreach
$ckdOrd as $key => $ord_no {
//update mysql here
}
