JS, PHP, MySQL Code errors for mathematical operation

JS, PHP, MySQL Code errors for mathematical operation - javascript

I wrote a small script. I have a form in my page. It takes data from MySQL Database. After that, When user select some options from select panels, I need JS will do math summation and write total in a div/input field.
I wrote the page and got errors. I changed a lot of things after searched similar problems on net and here.
I used parseInt($.. ,10) , document.getElementById("testID").innerHTML , document.getElementById("testID").value , document.getElementById("testID").val() and etc...
So, I'm asking your help to correct my errors.
Thanks
Here is the Jsfiddle page link;

My Code (this is the latest version that I have) ;
JS:
<script type="text/javascript">
function updatesum() {
var T = 0;
var d = document;
var A = d.getElementById("araclar").val();
var M = d.getElementById("varis").val();
var K = d.getElementById("kisiler").val();
var B = d.getElementById("bavullar").val();
var C = d.getElementById("cocuklar").val();
var Ck = d.getElementById("cocukKoltuk").val();
T = parseInt('A' ,10) * parseInt('M' ,10);
document.getElementById("toplamm").innerHTML = T;
}

In this line T = parseInt('A' ,10) * parseInt('M' ,10); you are using trying to get the ASCII code of char A and char M. Whereas you should be parsing variables A and M to integer.
You will need to modify your function as below to get the correct numbers-
T = parseInt(A ,10) * parseInt(M ,10);
Updated as per comment -
Use value instead of val() for getting the values form html id tags.
T = parseInt(A ,10) * parseInt(M ,10) + parseInt(K ,10) + parseInt(B ,10) + parseInt(C ,10) + parseInt(Ck ,10);

Stepformwizard is not getting hidden. Overflowing on right of the screen

Am not very expert in jquery and stepformwizard. Am working on code written by someone else. The issue is the multistepformwizard fieldset is used and the next step should be loaded only when Next button is clicked. But currently both of the steps are visible on the screen with extra horizontal scrollbar. I dont want the step 2 form to be visible. Here is the html and jquery code.

Multiple two inputs and the inputs generated dynamically by jQuery

I have this form and this is my layout:
I want when the user enters the quantity the total input = qty*price.

divtest.innerHTML = medo;
objTo.appendChild(divtest);
$('select').selectpicker();
}
function remove_education_fields(rid) {
$('.removeclass'+rid).remove();
}
</script>
and this 2nd jQuery used to get product price from from drop-menu attributes and add that into price input.
<script>
function set_price( slc ) {
var price = slc.find(':selected').attr('data-price');
slc.parent().parent().next().next().find('.price').val(price);
}
$('#education_fields').on('change','select.selectpicker',function(){
set_price( $(this) );
});
</script>

var sample = $('#sample').html();
$('#sample').on('click', '.generate', function() {
$('#sample').append(sample);
});
$('#sample').on('change', 'select.selectpicker', function () {
// keyword this is your current select element
var select = $(this);
// each group of inputs share a common .form element, so use that to
// look up for closest parent .form, then down for input[name="price[]"]
// and set the input's value
select.closest('.form').find('[name^=price]').val(
select.find('option:selected').data('price')
// trigger input's keyup event (*)
).keyup();
});
// (*) note: input[type=text]'s onchange event triggers only after it loses focus; we'll use keyup event instead
// create onkeyup event on the qty and price fields
$('#sample').on('keyup', '[name^=qty], [name^=price]', function() {
// get related form
var form = $(this).closest('.form');
// get its related values
var qty = parseInt(form.find('[name^=qty]').val(), 10),
price = parseInt(form.find('[name^=price]').val(), 10);
// ensure only numbers are given
if (!isNaN(qty) && !isNaN(price)) {
// set the total
form.find('[name^=total]').val(qty * price);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="sample">

Note, that I am lazy instead of doing [name="price[]"], I simply did [name^=price].
Edit changed onchange to keyup.

onchange dynamic dropdown values using php

I have written a code for two dropdown boxes. The first dropdown contains a list of main category dynamic values. when i select any one of the value in main category list the second dropdown should appear with corresponding sub category values. How can i do this?
Here is my code:
<div class="row">
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
Please Choose Your Category
</div>
</div>
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
<select class="form-control" name="category_name" onchange="mainInfo(this.value);">
<option value="" selected>Please Select</option>
<option value="Birds">Birds</option>
<option value="Animals">Animals</option>
<option value="Notinlist">Category Not in list</option>
</select>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
Please Choose Your Sub Category
</div>
</div>
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
<select class="form-control" name="album_name">
<option value="" selected>Please Select</option>
<option value="Birds">Sub Birds</option>
<option value="Animals">Sub Animals</option>
<option value="Notinlist">Category Not in list</option>
</select>
</div>
</div>
</div>
php code to fetch sub category for main category
<?php
$album_category = $_POST['category_name'];
$sql=$conn->prepare("select * from `albums` where album_category=:album_category");
$sql->bindParam(":album_category",$album_category);
$sql->execute();
while ($row = $sql->fetch(PDO::FETCH_ASSOC))
{
echo $row['album_sub_category'];
}
?>

Change your code to something like that :
<div class="row">
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
Please Choose Your Category
</div>
</div>
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
<select class="form-control" name="category_name" id="category_name" onchange="mainInfo(this.value);">
<option value="" selected>Please Select</option>
<option value="Birds">Birds</option>
<option value="Animals">Animals</option>
<option value="Notinlist">Category Not in list</option>
</select>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
Please Choose Your Sub Category
</div>
</div>
<div class="col-xs-6 col-sm-6 col-md-4 col-md-offset-1">
<div class="form-group">
<select class="form-control" name="album_name" id="album_name">
<option value="">Please Select</option>
</select>
</div>
</div>
</div>
Add this ajax function :
<script>
function mainInfo(str)
{
var n;
if (str=="0")
{
document.getElementById("album_name").innerHTML="<option>--Select --</option>";
return;
}
if (window.XMLHttpRequest)
{
n=new XMLHttpRequest();
}
else
{
n=new ActiveXObject("Microsoft.XMLHTTP");
}
n.onreadystatechange=function()
{
if (n.readyState==4 && n.status==200)
{
document.getElementById("album_name").innerHTML=n.responseText;
}
}
n.open("GET","sub_category.php&category_name="+str,true);
n.send();
}
</script>
And on the php page which is sub_category.php
<?php
$album_category = $_POST['category_name'];
$sql=$conn->prepare("select * from `albums` where album_category=album_category");
$sql->bindParam(":album_category",$album_category);
$sql->execute();?>
<option value="">--Select State--</option>
<?php
while ($row = $sql->fetch(PDO::FETCH_ASSOC))
{
?>
<option value="<?php echo $row['album_sub_category'];?>"><?php echo $row['album_sub_category'];?></option>
<?php
}
?>

Unless the items in the list are small enough preload load into the page, you're going to have to make an http endpoint for fetching the raw data using AJAX and then draw it on the client with JavaScript. jQuery would make light work of it.
The other option would involve reloading the page for each change... Yuck...
You're client code could be something like this with jQuery:
$.ajax({url: '/categories.json', data: {cat:'category name'}}).done(function(cats){
$.each(cats, function(){
$('#Target').append($('<option>', {value:this}).text(this));
})
}).fail(function(){
// Handle error
});
Since no method id specified it will default to GET and the data object will be converted to GET variables which you can use for the DB query to get the applicable sub categories and return them in JSON with proper JSON headers.

Jquery Select2 Make Dynamically

I want to generate Jquery select 2 when clicking a plus button. see below screenshot
the append functionality and removing rows are working perfectly from side.
I am initializing a div with display none for appending HTML.

<option value=""></option>
<?php
while($row9=mysql_fetch_assoc($brandfetchAjax)){ ?>
<option value="<?php echo $row9['ID'];?>"><?php echo $row9['BrandName'];?></option>
<?php } ?>
</select>

Jquery....
$(".addline").click(function(){
var eqtype = $("select[name=EquipmentTypeID]").val();
if(eqtype == ""){
$("select[name=EquipmentTypeID]").next().show();
return false;
}else{
$(".form-error").hide();
$(".apndarea").after($(".newbrndsrs").html());
}
});
But New Dynamic Select2 Not working....
I cant make click on it...
What is the Issue ?

$(document).on('click',".addline", function(){
var eqtype = $("select[name=EquipmentTypeID]").val();
if(eqtype == ""){
$("select[name=EquipmentTypeID]").next().show();
return false;
}else{
$(".form-error").hide();
$(".apndarea").after($(".newbrndsrs").html());
}
});
Click is not binded to dynamically created object, use on

Use Event deligation
$(document).on('click', ".addline", function () {
var eqtype = $("select[name=EquipmentTypeID]").val();
if (eqtype == "") {
$("select[name=EquipmentTypeID]").next().show();
return false;
} else {
$(".form-error").hide();
$(".apndarea").after($(".newbrndsrs").html());
}
});

How to display multiple form fields of the same type using jquery and fetch their values in php

I have a table named order_master which stores the order_id column. I also have another table order_details having the columns order_id (FK), vendor, purchase_date, delivery_date, and person_name which stores the details of the order corresponding to the order_id from the order_master table.
I want to display a form wherein a button add new item will be displayed. On clicking this button each time, a new block of fields (like vendor, purchase_date, delivery_date, person_name) will be displayed. The user can click the above button and enter as many items as he wants on the same order_id. And when he submits the form, the items on this form must be entered in the database.
How to achieve this?
actually i am using codeigniter framework (MVC architecture). Here i am attaching the view and js file.
<?php echo form_open(); ?>
<div id="emp"></div>
<div class="box">
<div>
</div>
<div class="col-lg-12" style="padding-top: 2%;margin-bottom: 3%" id="form-box">
<div class="col-lg-6 form-group">
<select name="item[]" id="item" class="form-control">
<option value="">--Select Item--</option>
<?php foreach ($items as $item) { ?>
<option value="<?php echo $item["id"]; ?>"><?php echo $item["name"]; ?></option>
<?php } ?>
</select>
</div>
<div class="col-lg-6 form-group">
<select name="vendor[]" id="vendor" class="form-control">
<option value="">--Select Vendor--</option>
<?php foreach ($vendors as $vendor) { ?>
<option value="<?php echo $vendor["id"]; ?>"><?php echo $vendor["name"]; ?></option>
<?php } ?>
</select>
</div>
<div class="col-lg-4 form-group">
<input type="text" name="po_date[]" id="po_date" class="form-control date" placeholder="Purchase Date">
</div>
<div class="col-lg-4 form-group">
<input type="text" name="quantity[]" id="quantity" class="form-control number" placeholder="Item Quantity Individual">
</div>
<div class="col-lg-4 form-group">
<input type="text" name="unit_price[]" id="unit_price" class="form-control number" placeholder="Unit Price" style="text-align: left;">
</div>
<div class="col-lg-4 form-group">
</div>
<div class="col-lg-12 col-md-12 col-sm-12 form-group">
<textarea name="description[]" id="description" class="form-control"></textarea>
</div>
<div class="col-lg-12 col-md-12 col-sm-12" style="height: 3px;background-color: grey"></div>
<div class="col-lg-12 col-md-12 col-sm-12 form-group" id="messageBox">
</div>
</div>
</div>
<a id="add_item" class="col-lg-12" href="">Add new item</a>
<div class="col-lg-12 col-md-12 col-sm-12 text-center form-group">
<input type="button" value="Add Purchase Order" id="addpurchaseOrderBtn" class="btn btn-primary">
</div>
<?php echo form_close(); ?>
**JS File**
$("#main_content").css('minHeight', '400px');
$(document).ready(function() {
$('#add_item').click(function() {
var def_ht = $("#main_content").height() + 300;
$("#main_content").css('minHeight', def_ht);
$("#form-box").clone(true).appendTo("#form-box");
return false;
});
$("#addpurchaseOrderBtn").click(function() {
focusId = null;
var isvalid = false;
if(validateDropDown('item')){
isvalid = true;
}
if(validateDropDown('vendor')){
isvalid = true;
}
if(validatDate('po_date')){
isvalid = true;
}
if(validateTextbox('quantity')){
isvalid = true;
}
if(validateTextbox('unit_price')){
isvalid = true;
}
if(validateTextbox('description')){
isvalid = true;
}
if(isvalid){
focusId.focus();
$("#messageBox").html('<div class="alert alert-danger">There are some error in your submission. Please try again.</div>');
}else{
$("#addPurchaseFrm").submit();
}
});
});
This code works but i am unable to validate all the elements(items) in the form.

You can try the following structure-
<form name="addItem" method="post" action="addItem.php" class="insertItem">
<div class="itemAdd">
<input type="text" name="vendor" >
<input type="text" name="purchase_date" >
<input type="text" name="delivery_date" >
<input type="text" name="person_name" >
</div>
<input type="submit" name="submit" value="Add Item" class="btn btn-primary additem">
$("document").ready(function(){
$(".additem").click(function(){
$(".insertItem").append($(".itemAdd").html);
});
});
Then on addItem.php, you can execute the insert query to insert this data into your database
