reading dynamically added input values into an array php - javascript

Every thing is working expect that on adding the dynamic fields,the input added is not captured into the array.Only the values in the only created input are read. HTML PART
<table class="table table-bordered table-hover order-list" >
<thead>
<tr><td>Product</td><td>Price (Ksh.) </td><td>Qty</td><td> (Ksh.)</td></tr>
</thead>
<tbody>
<tr>
<td><input type="text" class="form-control" name="product[]" required="" /></td>
<td><input type="text" class="form-control" name="price[]" required/></td>
<td><input type="text" class="form-control" name="quantity[]" /></td>
<td><input type="text" name="linetotal[]" readonly="readonly" /></td>
<td><a class="deleteRow"> x </a></td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="5" style="text-align: center;">
<input type="button" id="addrow" value="Add Product" />
</td>
</tr>
<tr>
<td colspan="5">
Grand Total: Ksh.<input type="text" name="grandtotal" readonly="readonly" /><span id="grandtotal"></span>
</td>
</tr>
</tfoot>
</table>
THE javascript to sum up the get the sub total and grand total is as below:
$(document).ready(function () {
var counter = 1;
$("#addrow").on("click", function () {
counter++;
var newRow = $("<tr>");
var cols = "";
cols += '<td><input type="text" name="product' + counter + '"/></td>';
cols += '<td><input type="text" name="price' + counter + '"/></td>';
cols += '<td><input type="text" name="quantity' + counter + '"/></td>';
cols += '<td><input type="text" name="linetotal' + counter + '" readonly="readonly"/></td>';
cols += '<td><a class="deleteRow"> x </a></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
});
$("table.order-list").on("change", 'input[name^="price"], input[name^="quantity"]', function (event) {
calculateRow($(this).closest("tr"));
calculateGrandTotal();
});
$("table.order-list").on("click", "a.deleteRow", function (event) {
$(this).closest("tr").remove();
calculateGrandTotal();
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
var qty = +row.find('input[name^="quantity"]').val();
var linetotal = +row.find('input[name^="linetotal"]').val((price * qty).toFixed(2));
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="linetotal"]').each(function () {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
}
the php part to read the array is
if(isset($_POST['cinvoice']) && $_SERVER["REQUEST_METHOD"] == "POST" &&is_array($_POST["product"]) && is_array($_POST["quantity"]) && is_array($_POST["price"]) && is_array($_POST["linetotal"]))
{
$recordid="";
$firstname="";
$product="";
$quantity="";
$price="";
$linetotal="";
foreach ($_POST["product"] as $key => $prod) {
$product .= $prod.",";
}
foreach ($_POST["quantity"] as $key => $qty){
$quantity.=$qty. ",";
}
foreach ($_POST["price"] as $key => $prc) {
$price.=$prc. ",";
}
foreach ($_POST["linetotal"] as $key => $linetotal) {
$linetotal.=$linetotal. ",";
}

you should pass textbox name as an array:
cols += '<td><input type="text" name="product[]"/></td>';
cols += '<td><input type="text" name="price[]"/></td>';
cols += '<td><input type="text" name="quantity[]"/></td>';
cols += '<td><input type="text" name="linetotal[]" readonly="readonly"/>
Also you can use implode function in php
foreach ($_POST["product"] as $key => $prod) {
$product .= $prod.",";
}
to
$product = implode(',', $_POST["product"])

Autonumbering is not working on added rows

I have 2 functions. Add dynamic rows and Autonumbering. My problem is, my autonumbering is not working on my dynamically added rows. I wonder what could be the problem? The "class="form-control" is all the same for my input type field. However, it is still not working. I have provided my js fiddle below.
https://prnt.sc/124vuju
https://jsfiddle.net/rain0221/59k4c0yg/3/ // in "lb" column, type any number and hit ctrl+enter in order to do autonumbering
//this is my function for autonumbering
const inputs = document.querySelectorAll(".form-control");
inputs[0].addEventListener("keyup", e => {
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
inputs.forEach((inp, i) => {
if (i !== 0) {
inp.value = ++value;
}
})
}
})
//this is my function for adding dynamic rows.
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" id="auto" value="" class="form-control" type="number" readonly /></td>"' +

You need to find the elements inside eventListener event. Since you are finding the element global onload so if will not hold the elements added dynamically. You can move the blow code inside addEventListener keyup event.
const inputs = document.querySelectorAll(".form-control");
To attach the keyup event, you can use document.querySelectorAll(".form-control")[0] instead of inputs[0].
document.querySelectorAll(".form-control")[0].addEventListener("keyup", e => {
const inputs = document.querySelectorAll(".form-control");
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
inputs.forEach((inp, i) => {
if (i !== 0) {
inp.value = ++value;
}
})
}
});
I can see that you have assigned the 'form-control' class only for LB# column so autonumber will be generate only for LB#. In case you want to generate autonumber for all the columns, assign the class="form-control" to each added dynamically.
The problem is that you are addding keyup listeners only to those elements that are already present in the DOM at the time you are adding them.
What you need instead is called delegate listeners, and it means that you rely on the mechanism that most events bubble up in the DOM, allowing you to attach the keyup listener to an element that is an ancestor to all the input elements of interest.
Inside that listener, you then check if the element they event came from is one you want to handle.
//this is my function for autonumbering
const inputAncestor = document.querySelector("tbody");
inputAncestor.addEventListener("keyup", e => {
if (
e.target.matches('input.form-control') &&
((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10))
) {
const inputs = document.querySelectorAll(".form-control");
let value = parseInt(e.target.value);
inputs.forEach((inp) => {
if (inp !== e.target) {
inp.value = ++value;
}
})
}
})
//this is my function for adding dynamic rows.

Unfortunately, your code has several more problems, which I tried to fix.
As mentioned in the first comment to your question, you cannot have a div as a child of tbody. Only tr is allowed here.
You are using duplicate id value auto. That is invalid HTML.
In your markup, you have the class form-control on all the inputs. In your dynamically added markup it's only on the first input. Which version is the correct one?
In your tfoot you had the button as direct child. This is, again, invalid HTML. The only child element(s) tfoot can have is tr.
The very first row in your table describes the columns and acts as your table's header, yet it did not reside in the thead part of your table.

Get all values per table column dynamically using javascript or jquery

Table data disappearing upon live search

I am generating dynamic textboxes on button click in a table.
On button click i am calling Details() which appends a new row to the table:
function Details(id,name)
{
var html = '';
html += '<tr>';
html += '<td><input type="text" name="item_id[]" value="'+ id +'" class="form-control item_id" autofocus required /></td>';
html += '<td><input type="text" name="item_name[]" value="'+ name +'" class="form-control item_name" required /></td>';
html += '<td style="text-align:center"><button type="button" name="remove" class="btn btn-danger btn-sm order_item_remove"><span class="glyphicon glyphicon-minus"></span></button></td></tr>';
$("#table").append(html);
}
But when i try to live search the data from the table then its rows disappear.
Live Search:
$("#search_field").keyup(function() {
var count = 0;
var value = this.value.toLowerCase().trim();
$("#table").find("tr").each(function(index) {
if (index === 0) return;
var id = $(this).find("td").text().toLowerCase().trim();
$(this).toggle(id.indexOf(value) !== -1);
if(id.indexOf(value) !== -1){
count = count+1;
}
});
});
Table:
<table class="table table-bordered" id="table">
<tr>
<th>ID</th>
<th>Name</th>
</tr>
</table>
What am i doing wrong?? Any help would be appreciated.
You can use this (edited to use non-ES6 syntax):
var rowMatches = $(this)
.find(':input')
.toArray()
.some(function(input) { return $(input).val().toLowerCase().trim().indexOf(value) !== -1; });
$(this).toggle(rowMatches);
Explanation
.text() is not meant to grab input vales.
You need to use .val(). But since there can be multiple inputs per rows, you want to check whether at least one cell matches the filter.
.toArray() transforms the set of nodes into an array,
Array#some returns true if at least one cell's value matches the filter string.
Demo using the rest of your code
$("#search_field").keyup(function() {
var count = 0;
var value = this.value.toLowerCase().trim();
$("#table").find("tr").each(function(index) {
if (index === 0) return;
var rowMatches = $(this)
.find(':input')
.toArray()
.some(function(input) { return $(input).val().toLowerCase().trim().indexOf(value) !== -1; });
$(this).toggle(rowMatches);
if (rowMatches) {
count = count + 1;
}
});
});
function Details(id, name) {
var html = '';
html += '<tr>';
html += '<td><input type="text" name="item_id[]" value="' + id + '" class="form-control item_id" autofocus required /></td>';
html += '<td><input type="text" name="item_name[]" value="' + name + '" class="form-control item_name" required /></td>';
html += '<td style="text-align:center"><button type="button" name="remove" class="btn btn-danger btn-sm order_item_remove"><span class="glyphicon glyphicon-minus"></span></button></td></tr>';
$("#table").append(html);
}
Details(1, 'foo');
Details(2, 'bar');

var price = parseInt( $('input[id^=price]', this).val(), 10 );
var qty = parseInt( $('input[id^=qty]' , this).val(), 10 );
$('input[id^=linetotal]', this).val(price * qty);
});
So currently I cant get the js to fire that gets the product of the two cells, qty and price. I want to display result in linetotal.
The last part of this would be to display the sum of all linetotals as a grand total in the div grandtotal
Help appreciated as always.
You're only giving the elements a name attribute, but using the id selector ([id^=price]). It's much easier to give them a specific class than having to use that "id starts with" selector. Also, when do you want the line totals to be calculated? And when do you want the grand total to be calculated? On what event(s)?
Here's my interpretation of how it should look:
<table class="order-list">
<thead>
<tr><td>Product</td><td>Price</td><td>Qty</td><td>Total</td></tr>
</thead>
<tbody>
<tr>
<td><input type="text" name="product" /></td>
<td>$<input type="text" name="price" /></td>
<td><input type="text" name="qty" /></td>
<td>$<input type="text" name="linetotal" readonly="readonly" /></td>
<td><a class="deleteRow"> x </a></td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="5" style="text-align: center;">
<input type="button" id="addrow" value="Add Product" />
</td>
</tr>
<tr>
<td colspan="5">
Grand Total: $<span id="grandtotal"></span>
</td>
</tr>
</tfoot>
</table>
And the JS:
$(document).ready(function () {
var counter = 1;
$("#addrow").on("click", function () {
counter++;
var newRow = $("<tr>");
var cols = "";
cols += '<td><input type="text" name="product' + counter + '"/></td>';
cols += '<td>$<input type="text" name="price' + counter + '"/></td>';
cols += '<td><input type="text" name="qty' + counter + '"/></td>';
cols += '<td>$<input type="text" name="linetotal' + counter + '" readonly="readonly"/></td>';
cols += '<td><a class="deleteRow"> x </a></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
});
$("table.order-list").on("change", 'input[name^="price"], input[name^="qty"]', function (event) {
calculateRow($(this).closest("tr"));
calculateGrandTotal();
});
$("table.order-list").on("click", "a.deleteRow", function (event) {
$(this).closest("tr").remove();
calculateGrandTotal();
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
var qty = +row.find('input[name^="qty"]').val();
row.find('input[name^="linetotal"]').val((price * qty).toFixed(2));
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="linetotal"]').each(function () {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
}

In your JS, you weren't using linetotal for the one dynamic input's name. There were other several minor modifications I made. You might as well use <thead>, <tbody> and <tfoot> since you do have those sections in the <table>. Also, I don't think it's a good design to have a new row automatically added when the "product" inputs are changed. That can happen often, and their intent may not be to add a new product...a button is much more friendly. For example, say you type in "asdf" to the first "product" input, then click somewhere. A new row is added. Say you made a typo so you go back and change it to "asd", then click somewhere. Another new row is added. That doesn't seem right.
This function should do the trick:
function updateGrandTotal() {
var prices = [];
$('input[name^="price"]').each(function () {
prices.push($(this).val());
});
var qnts = [];
$('input[name^="qty"]').each(function () {
qnts.push($(this).val());
});
var total = 0;
for(var i = 0; i < prices.length; i++){
total += prices[i] * qnts[i];
}
$('#grandtotal').text(total.toFixed(2));
}
You just need to bind it to the table change event to update the grand total every time an input changes:
$("table.order-list").change(updateGrandTotal);
Here is a working fiddle.
