POST data doesn't contain any form data - javascript

I have a table with a form in it. However, when I hit the submit button, by POST data doesn't contain any of the input data... any ideas why?
<table class="table table-hover" name="share_table">
<thead>
<tr>
<th>●</th>
<th>Name</th>
<th>Email</th>
<th>Allocation</th>
<th></th>
</tr>
</thead>
<form id="myform" action="" method="post">
<tbody>
<tr>
<th scope="row">●</th>
<td><input type="text" id="name" placeholder="eg. John Smith" class="form-control"></td>
<td><input type="email" id="email" placeholder="eg. john#email.com" class="form-control"></td>
<td><input type="text" id="allocation" placeholder="1000" class="form-control"></td>
<td></td>
</tr>
</tbody>
</table>
<div class="text-right">
<p>
<input type="submit" value="Create Project" class="cta"/>
</form>
</p>
</div>
<button class="cta" name="add">Add</button>
I'm adding and removing rows using jquery as such - not pretty but I'm a novice when it comes to js.
<script>
var inx = 1;
</script>
<script>
function removex(ref){
$(ref).remove();
};
</script>
<script>
jQuery(document).ready(function() {
$('button[name="add"]').on('click', function(){
var table = $('table[name="share_table"]');
inx = inx + 1;
var trx = '<tr id="row' + inx.toString() + '" />';
var tr = $(trx);
var td = $('<td />');
var idrow = $('<th scope="row"/>').html('●');
var input = $('<input placeholder="1000" />').attr({'class' : 'form-control'});
var inputz = $('<input placeholder="eg. john#email.com"/>').attr({'class' : 'form-control'});
var inputx = $('<input placeholder="eg. John Smith" />').attr({'class' : 'form-control'});
var bx = '<a href="#" onclick="removex(row' + inx.toString() ;
var bxx = bx + ')"> x</a>';
var button = $(bxx);
var namex = 'name' + inx.toString();
var emailx = 'email' + inx.toString();
var allocationx = 'allocation' + inx.toString();
var tdName = td.clone().append(inputx.attr({'type': 'text', 'id': namex}));
var tdEmail = td.clone().append(inputz.attr({'type': 'email', 'id': emailx}));
var tdAllocation = td.clone().append(input.attr({'type': 'text', 'id': allocationx}));
var tdRow = td.clone().append(idrow);
var tdAction = td.clone().html(button);
tr.append(tdRow);
tr.append(tdName);
tr.append(tdEmail);
tr.append(tdAllocation);
tr.append(tdAction);
table.append(tr);
});
});
</script>

I think it is because you didn't put a page link in your action in the form tag

My submited table does not show on the browser

I have a scoreboard where the user can enter the score and when the user presses the "Submit" button it will show a table that will contain the information that the user has entered. But when I try it in the browser, my table doesn't show the information that was entered in the previous form, it only show the table heading. Let me explain like below:
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physical = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
// Add the information but why it does not work
var table = document.getElementById("tableScore");
var row = table.insertRow(i);
var number = row.insertCell(0);
var name = row.insertCell(1);
var math = row.insertCell(2);
var physics = row.insertCell(3);
var chemistry = row.insertCell(4);
var avg = row.insertCell(5);
number.innerHtml = i;
name.innerHtml = testScore.name;
math.innerHtml = testScore.math;
physics.innerHtml = testScore.physics;
chemistry.innerHtml = testScore.chemistry;
avg.innerHtml = testScore.avg;
i++;
}

In js code you have used innerHtml instead of innerHTML.
Updated code:
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physical = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
// Add the information but why it does not work
var table = document.getElementById("tableScore");
var row = table.insertRow(i);
var number = row.insertCell(0);
var name = row.insertCell(1);
var math = row.insertCell(2);
var physics = row.insertCell(3);
var chemistry = row.insertCell(4);
var avg = row.insertCell(5);
number.innerHTML = i;
name.innerHTML = testScore.name;
math.innerHTML = testScore.math;
physics.innerHTML = testScore.physics;
chemistry.innerHTML = testScore.chemistry;
avg.innerHTML = testScore.avg;
i++;

When you use insertCell you need to use innerHTML or appendChild instead of the non-existent innerHtml
Also you do not need to have any integer in insertCell/Row
Also your HTML was invalid
number.appendChild(document.createTextNode(i));
name.appendChild(document.createTextNode(testScore.name));
math.appendChild(document.createTextNode(testScore.math));
physics.appendChild(document.createTextNode(testScore.physics));
chemistry.appendChild(document.createTextNode(testScore.chemistry));
avg.appendChild(document.createTextNode(testScore.avg));
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physics = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
// Add the information but why it does not work
var table = document.querySelector("#tableScore tbody");
var row = table.insertRow();
var number = row.insertCell();
var name = row.insertCell();
var math = row.insertCell();

You have some misspelled variables but you can also minimize your output with only one global innerHTML like in my example below:
var testScore = {
name: "",
math: 0,
physical: 0,
chemistry: 0,
avg: 0
};
var i = 1;
// This is the table will show after submited
function score_table() {
document.getElementById("divTable").style.display = "block";
// Gathering the data
testScore.name = document.getElementById("name").value;
testScore.math = document.getElementById("math").value;
testScore.physical = document.getElementById("physics").value;
testScore.chemistry = document.getElementById("chemical").value;
testScore.avg = (parseFloat(testScore.math) + parseFloat(testScore.physics) + parseFloat(testScore.chemistry)) / 3;
// How to get this average score has the form like 8,33 or 6,69, I need //help
document.getElementById("name").value = "";
document.getElementById("math").value = "";
document.getElementById("physics").value = "";
document.getElementById("chemical").value = "";
//MINIMIZED VERSION
document.getElementById("tableScore").innerHTML +=
"<td>" + i + "</td>" +
"<td>" + testScore.name + "</td>" +
"<td>" + testScore.math + "</td>" +
"<td>" + testScore.physical + "</td>" +
"<td>" + testScore.chemistry + "</td>" +
"<td>" + testScore.avg + "</td>";
i++;
}

#tableScore td:nth-child(6) {

I want to add new data from second table to main table

I want to add new data to the main table using the checkbox option, but the data added is not the same as the selected data. this is my code ...
<table border="1" id="table2">
<tr>
<td>Raka</td>
<input type="hidden" id="fname" value="Raka">
<td>Gilbert</td>
<input type="hidden" id="lname" value="Gilbert">
<td><input type="checkbox" name="chk"></td>
</tr>
<tr>
<td>Achyar</td>
<input type="hidden" id="fname" value="Achyar">
<td>Lucas</td>
<input type="hidden" id="lname" value="Lucas">
<td><input type="checkbox" name="chk"></td>
</tr>
</table>
<script>
$(document).on('click', '#Add', function() {
$("table").find('input[name="chk"]').each(function(){
if($(this).is(":checked")){
var fname = $('#fname').val();
var lname = $('#lname').val();
var newData = '<tr>'+
'<td>'+fname+'</td>'+
'<td>'+lname+'</td>'+
'<tr>';
$('table').append(newData);
}
});
})
</script>
You need to change your id="fname" to class="fname" and get the input value closest to checkbox. Currently you are getting data from the first inputs as they have the same id's.
function valueExists(value) {
if (!value) {
return true;
}
let exists = false;
$("#main-table").find('tr').each(function() {
let fname = $(this).find("td:nth-child(1)").text(),
lname = $(this).find("td:nth-child(2)").text();
const fullName = `${fname}${lname}`;
if (value.toLowerCase() === fullName.toLowerCase()) {
exists = true;
}
});
return exists;
}
$(document).on('click', '#add', function() {
$("table").find('input[name="chk"]').each(function(e) {
if ($(this).is(":checked")) {
var fname = $(this).parents('tr').find('.fname').val();
var lname = $(this).parents('tr').find('.lname').val();
if (valueExists(`${fname}${lname}`)) return;
var newData = '<tr>' +
'<td>' + fname + '</td>' +
'<td>' + lname + '</td>' +
'<tr>';
$('#main-table').append(newData);
}
});
})
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>

<input type="hidden" class="lname" value="Lucas">
<td><input class="check" type="checkbox" name="chk"></td>
</tr>
</table>
<button type="button" id="add" name="button">Add</button>
Try this. I have used plain javascript
document.addEventListener("click", function() {
[...document.querySelectorAll("input[name='chk']")].forEach(data => {
console.log(data);
if (data.checked) {
const fname = document.getElementById("fname").value;
const lname = document.getElementById("lname").value;
const newData = `<tr><td>${ fname }</td><td>${ lname }</td</tr>`;
// "<tr>" + "<td>" + fname + "</td>" + "<td>" + lname + "</td>" + "<tr>";
document.getElementById("table2").innerHTML += newData;
}
});
});
Hope was useful. If any flaws please update
Here is a neater solution, using 2 tables as requested, without hidden inputs and a better use of 'tables' and 'trs' in jquery
$(function(){
$("#btnAdd").click(function(){
let table1 = $("#table1");
table2 = $("#table2");
$.each(table2.find('tr'), function(i, tr){
tr = $(tr);
let new_tr = $('<tr>');
if (tr.find("td input").is(":checked")) {
let fname = tr.find("td:nth-child(1)").html(),
lname = tr.find("td:nth-child(2)").html();
new_tr.append(
'<td>' + fname + '</td>' +
'<td>' + lname + '</td>' +
'<td><input type="checkbox" name="chk"></td>'
);
table1.append(new_tr)
}
})
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

how to insert generated html table data into database in php?

How I can insert all data from a generated HTML table into my database using PHP?
I have tried with a foreach loop, but it gives me an error all the time.
I have this code in JavaScript to adding a new row using a button:
var i=1;
function addRow()
{
var tbl = document.getElementById('table1');
var lastRow = tbl.rows.length;
var iteration = lastRow - 1;
var row = tbl.insertRow(lastRow);
var firstCell = row.insertCell(0);
var el = document.createElement('input');
el.type = 'text';
el.name = 'to' + i;
el.id = 'to' + i;
el.size = 40;
firstCell.appendChild(el);
var secondCell = row.insertCell(1);
var el2 = document.createElement('input');
el2.type = 'text';
el2.name = 'cost' + i;
el2.id = 'cost' + i;
el2.size = 40;
secondCell.appendChild(el2);
frm.h.value=i;
i++;
}
And this is my HTML code:
<table id="table1" width="40%" border="2" cellpadding="0" cellspacing="0">
<tr>
<td><strong>To Address</strong></td>
<td><strong>Delivery Cost</strong></td>
</tr>
<tr>
<td><input name="to" type="text" id="to" size="40"/></td>
<td><input name="cost" type="text" id="cost" size="40"/></td>
</tr>
</table>
<br/><br/>
<input style="float: right;background-color: #57a000;height: 30px;font-weight: bold; font-family: cursive;margin-left: 10px;"
type="submit" value="Save All" name="SaveCost"/>
<input style="float: right;background-color: #57a000;height: 30px;font-weight: bold; font-family: cursive;"
type="button" value="Add New Place" onclick="addRow();"/>
<input name="h" type="hidden" id="h" value="0"/>
Finally I want to write some PHP to insert all the data from the generated HTML table into my database.

how to obtain data from dynamic rows created in Javascript into html tag?

There is form which has table containing 1 row and 4 column.The add row button creates a exact row but with different ids .I want to obtain the data filled in this form and send to a php script when clicked on save and continue later button at the bottom .How can I do this?This being a html page.
<form name="myform">
<h3 align="left"><b>Computer</b><h3>
<table id="POITable" border="1" width="100%">
<tr>
<th style="width:10%">Sr No.</th>
<th>Item Description</th>
<th>Quantity</th>
<th>Rate(Inclusive of Taxes)</th>
<th>Total Cost</th>
</tr>
<tr>
<td>1</td>
<td><textarea rows="4" cols="50" id="comp_item"></textarea></td>
<td><input size=25 type="number" id="comp_quant"/></td>
<td><input size=25 type="number" id="comp_rate"/></td>
<td><input size=25 type="number" id="comp_total"/></td>
</tr>
</table>
Total:<input type="text" name="computer" align="right"><br>
<input type="button" id="addmorePOIbutton" value="Add New Row" onclick="insRow()"/>
<script>
function insRow()
{
console.log( 'hi');
var x=document.getElementById('POITable');
var new_row = x.rows[1].cloneNode(true);
var len = x.rows.length;
new_row.cells[0].innerHTML = len;
var inp1 = new_row.cells[1].getElementsByTagName('textarea')[0];
inp1.id += len;
inp1.value = '';
var inp2 = new_row.cells[2].getElementsByTagName('input')[0];
inp2.id += len;
inp2.value = '';
var inp3 = new_row.cells[3].getElementsByTagName('input')[0];
inp3.id += len;
inp3.value = '';
var inp4 = new_row.cells[4].getElementsByTagName('input')[0];
inp4.id += len;
inp4.value = '';
x.appendChild( new_row );
document.getElementsByName("len")[0].value=len;
}
</script>
<input type="submit" value="SAVE AND CONTINUE LATER">
</form>
</html>
To retrive your data in php you must add name attributes to your form input-fields. I have rewritten your code by replacing the input-id's with name instead, like so:
<td><textarea rows="4" cols="50" name="comp_item"></textarea></td>
<td><input size=25 type="number" name="comp_quant"/></td>
<td><input size=25 type="number" name="comp_rate"/></td>
<td><input size=25 type="number" name="comp_total"/></td>
also in your form-element you must specify action and method.
<form name="myform" action="myphpformhandler.php" method="POST">
I took the liberty to rewrite some of your code but the essentials are intact.
<form name="myform" action="myphpformhandler.php" method="POST"> <!-- point action towards the php-file where you wish to handle your data -->
<h3 align="left"><b>Computer</b><h3>
<table id="POITable" border="1" width="100%">
<tr>
<th style="width:10%">Sr No.</th>
<th>Item Description</th>
<th>Quantity</th>
<th>Rate(Inclusive of Taxes)</th>
<th>Total Cost</th>
</tr>
<tr>
<td>1</td>
<td><textarea rows="4" cols="50" name="comp_item"></textarea></td>
<td><input size=25 type="number" name="comp_quant"/></td>
<td><input size=25 type="number" name="comp_rate"/></td>
<td><input size=25 type="number" name="comp_total"/></td>
</tr>
</table>
Total:<input type="text" name="computer" align="right"><br>
<input type="button" id="addmorePOIbutton" value="Add New Row"/>
<input type="submit" value="SAVE AND CONTINUE LATER">
</form>
<script>
(function() { // Prevent vars from leaking to the global scope
var formTable = document.getElementById('POITable');
var newRowBtn = document.getElementById('addmorePOIbutton');
newRowBtn.addEventListener('click', insRow, false); //added eventlistener insetad of inline onclick-attribute.
function insRow() {
var new_row = formTable.rows[1].cloneNode(true),
numTableRows = formTable.rows.length;
// Set the row number in the first cell of the row
new_row.cells[0].innerHTML = numTableRows;
var inp1 = new_row.cells[1].getElementsByTagName('textarea')[0];
inp1.name += numTableRows;
inp1.value = '';
var inp2 = new_row.cells[2].getElementsByTagName('input')[0];
inp2.name += numTableRows;
inp2.value = '';
var inp3 = new_row.cells[3].getElementsByTagName('input')[0];
inp3.name += numTableRows;
inp3.value = '';
var inp4 = new_row.cells[4].getElementsByTagName('input')[0];
inp4.name += numTableRows;
inp4.value = '';
// Append the new row to the table
formTable.appendChild( new_row );
document.getElementsByName("len")[0].value = numTableRows;
}
})();
</script>
Now to access your data in your "myphpformhandler.php" you use the $_POST-variable with your html-element names. like so!
$_POST['comp_item'];
$_POST['comp_item1'];
$_POST['comp_quant'];
$_POST['comp_quant1']; //etc...
