Combining two or more submit buttons into one

I have submit buttons for different section of the webpage. The submit button is used to update the forms and database with the text value in the form fields. Currently, each submit button updates the forms (tied to their respective PKEY id, "consideration_no") only in their own sections. I want to update all the sections forms with one button click.
As you can see from the code below, there are 2 submit buttons. I have tried to link two together through IDs but it did not work for me.
// Include config file
require_once "config.php";

$consideration_no = $_REQUEST['consideration_no'];
$answer = $_POST['answer'];
// Check input errors before inserting in database
if(empty($answer_err)){
// Validate address address
$input_answer = trim($_POST["answer"]);

I want it to update all the fields, in different sections, with one submit button

your code was bit difficult to read, but from what i understood you are trying to combine two or more form submissions into one. It's quiet simple
<form method="POST" action="save.php">
<input type=text name=name[] />
<input type=text name=name[] />
</form>
by using the [] to identify the input element you can have multiple values with the same name where you can access them from the PHP script as an array.
For example the above example will produce an array as follows
<?php
print_r($_POST['name']); //("name" => Array....
is this clear enough for you? if not drop a comment, i will explain more. As a side note i do recommend you look into using template engine, and also a framework in your coding project.

Here's what I see when i separate the html into a new file. I tried to remove the excess forms but when I open the last collapsible section, it instantly executes a submit action and brings me back to the home page.
<button class="collapsible"><?php echo $section ?></button>
<div class="content">
<button class="collapsible"><?php echo $subsection ?></button>
<form action="<?php echo htmlspecialchars(basename($_SERVER['REQUEST_URI'])); ?>" method="post">
<?php
//while loop start
?>
<form action="<?php echo htmlspecialchars(basename($_SERVER['REQUEST_URI'])); ?>" method="post">
<div class="form-group <?php echo (!empty($answer_err)) ? 'has-error' : ''; ?>">
<label><?php echo $question; ?></label>
<input type="text" name="answer[]" class="form-control" value="<?php echo $answer; ?>">
<span class="help-block"><?php echo $answer_err;?></span>
<input type="hidden" name="consideration_no[]" value="<?php echo $consideration_no; ?>"/>
<input type="hidden" name="dg_no" value="<?php echo $dg_no; ?>"/>
</div>
<?php
//while loop ends
?>
<input type="Submit" name = "$consideration_no[]" class="btn btn-primary" value="Submit">
Cancel
</form>
</div>
<?php
//while loop start
?>
<form action="<?php echo htmlspecialchars(basename($_SERVER['REQUEST_URI'])); ?>" method="post">
<div class="form-group <?php echo (!empty($answer_err)) ? 'has-error' : ''; ?>">
<label><?php echo $question; ?></label>
<input type="text" name="answer[]" class="form-control" value="<?php echo $answer; ?>">
<span class="help-block"><?php echo $answer_err;?></span>
<input type="hidden" name="consideration_no[]" value="<?php echo $consideration_no; ?>"/>
<input type="hidden" name="dg_no" value="<?php echo $dg_no; ?>"/>
</div>
<?php
//while loop ends
?>
<input type="Submit" name = "$consideration_no[]" class="btn btn-primary" value="Submit">
Cancel
</form>
</div>

JSon array increment my id value from $_POST['id']

In my php script, I have managed to get all the data from a form into a json database, however everytime I submit my form, the id value is always == 1. How would I be able to change this, and add more values to my id value, like value++? How would I be able to do that?
<?php
$message = '';
$error = '';
if(isset($_POST["submit"]))
{
if(empty($_POST["title"]))
{
$error = "<label class='text-danger'>Enter title</label>";
echo $error;
}
else if(empty($_POST["decs"]))
{
$error = "<label class='text-danger'>Enter Gender</label>";
echo $error;
}
else if(empty($_POST["cont"]))
{
$error = "<label class='text-danger'>Enter Designation</label>";
echo $error;
}
else
{
if(file_exists('postbl.json'))
{
$current_data = file_get_contents('postbl.json');
$array_data = json_decode($current_data, true);
$extra = array(
'id' => $_POST['id'],
'title' => $_POST['title'],
'decs' => $_POST["decs"],
'cont' => $_POST["cont"]
);
$array_data[] = $extra;
$final_data = json_encode($array_data);
if(file_put_contents('postbl.json', $final_data))
{
$message = "<label class='text-success'>File Appended Success fully</p>";
echo $message;
}
}
else
{
$error = 'JSON File not exits';
}
}
}
?>
my form is like this
<?php session_start();
if(!isset($_SESSION['loggedin'])) header("Location: session.php");
if($_SESSION['loggedin']===FALSE) header("Location: session.php");
?>
<!DOCTYPE html>
<html><head><title>Secret Area</title></head>
<body>
<form action="/admin/form_process.php" method="POST">
<br />
<input type="hidden" name="id" value="1" />
<label>Title</label>
<input type="text" name="title" class="form-control" /><br />
<label>Description</label>
<input type="text" name="decs" class="form-control" /><br />
<label>Content</label>
<input type="text" name="cont" class="form-control" /><br />
<input type="submit" name="submit" value="Append" class="btn btn-info" /><br />
<?php
if(isset($message))
{
echo $message;
}
?>
</form>
<form action="logout.php" method="POST">
<input type="submit" name="logout" value="Log out">
</form>
<p>© 2017 Blog Message</p>
</body>
</html>

Your problem is here
<input type="hidden" name="id" value="1" />
Notice how the 1 is set as value.
Change the 1 with a variable. Something like
<input type="hidden" name="id" value="<?= $id ?>" />

js submit not works not sending post form data to php

After certain time (2min) when i try form submit using javascript it just submit form without post data value !!! searched solution on web but unable to find solution!! Hope someone can help me
Code:
<script type="text/javascript">
$(function() {
$('.countdown.callback').countdown({
date: +(new Date) + 120000,
render: function(data) {
$(this.el).text( this.leadingZeros(data.min, 2) + "min " + this.leadingZeros(data.sec, 2) + " sec");
if(this.leadingZeros(data.min, 2) < 01 && this.leadingZeros(data.sec, 2) <= 10){
$(this.el).addClass('ended');
}
},
onEnd: function() {
document.getElementById('myform').submit();
}
});
});
</script>
html code with php
<?php
foreach($row as $r){
if(!empty($r['question'])){
?>
<form method="post" id="myform" action="subanswer.php" >
<p><span style="color:rgb(33,79,157);"><?php echo $r['id'];?> <?php echo $r['question'];?></span><br />
<input type="radio" name="<?php echo $r['test_id'].'_'.$r['id'];?>" value="<?php echo $r['ans1'];?>"> <?php echo $r['ans1'];?>
<br>
<input type="radio" name="<?php echo $r['test_id'].'_'.$r['id'];?>" value="<?php echo $r['ans2'];?>"> <?php echo $r['ans2'];?>
<br>
<input type="radio" name="<?php echo $r['test_id'].'_'.$r['id'];?>" value="<?php echo $r['ans3'];?>"> <?php echo $r['ans3'];?>
<input type="hidden" name="testname" value="<?php echo $_GET['id']?>">
</p>
<?php
}
}
?>
<input type="submit" name="subans" value="add" class="but" style="width:15%;" />
</form>

From your code, it looks like you're calling the wrong form:
document.getElementById('myForm').submit();
The ID myFom does not exist. You have:
<form method="post" id="myform1" action="subanswer.php" >
Also not sure why people don't stick to JQuery throughout. Would advise:
$("#myForm1").submit();

SESSION variable slow to update textfield in php

I have a form, contained 3 fields, which when the submit button in submitted,
it will changes the session variable values according to the fields, in this case there are 3 variables. then i echo back the variable onto the fields.
For the first time submit, it stores the value beautifully and display in the fields correctly, the problem is that, when i submit the second time, the values are still the same. after i refresh the page, then the values in the fields are changed.
this is partially the codes i'm using now.
<?php
session_start();?>
?>
<form name="form1" id="form1" action="">
<input type="text" name="acc1" value="<?php echo $_SESSION['acc_main']" />
<input type="text" name="acc2" value="<?php echo $_SESSION['acc_id']" />
<input type="text" name="acc3" value="<?php echo $_SESSION['acc_cat']" />
<input type="submit" name="submit">
</form>
<?php
if(isset($_POST['submit']) != '')
{
$_SESSION['acc_main'] = $_POST['acc1'];
$_SESSION['acc_id'] = $_POST['acc2'];
$_SESSION['acc_cat'] = $_POST['acc3'];
}
?>
After i refresh(F5), then the value changed. i want it to be, when i clicked the submit button, it will change to the new value.

PHP Code:
<?php
if(isset($_POST['submit']) != '')
{
$_SESSION['acc_main'] = $_POST['acc1'];
$_SESSION['acc_id'] = $_POST['acc2'];
$_SESSION['acc_cat'] = $_POST['acc3'];
echo '<script type="text/javascript">'
, 'jsfunctionToPrintUpdatedValues();'
, '</script>'
;
}
?>
Javascript Sample Code
function jsfunctionToPrintUpdatedValues()
{
/* retrieve the updated session variables in javascript variables */
var acc_main_js = <?php echo $_SESSION['acc_main']?>
var acc_id_js = <?php echo $_SESSION['acc_id']?>
var acc_cat_js = <?php echo $_SESSION['acc_cat']?>
document.getElementById("main").value=acc_main_js;
document.getElementById("id").value=acc_main_js;
document.getElementById("cat").value=acc_main_js;
}

in the input fields you have to write like this
`
Below
`
<input type="text" name="acc1" value="<?php if(isset($_SESSION['acc_main'])) echo $_SESSION['acc_main']" />

Use if(isset($_POST['submit']) != '') before the form. Change your code to this:
<?php
session_start();
if(isset($_POST['submit']) != '')
{
$_SESSION['acc_main'] = $_POST['acc1'];
$_SESSION['acc_id'] = $_POST['acc2'];
$_SESSION['acc_cat'] = $_POST['acc3'];
?>
<form name="form1" id="form1" action="">
<input type="text" name="acc1" value="<?php echo $_SESSION['acc_main']" />
<input type="text" name="acc2" value="<?php echo $_SESSION['acc_id']" />
<input type="text" name="acc3" value="<?php echo $_SESSION['acc_cat']" />
<input type="submit" name="submit">
</form>
<?php
}else{
?>
<form name="form1" id="form1" action="">
<input type="text" name="acc1" value="<?php echo $_SESSION['acc_main']" />
<input type="text" name="acc2" value="<?php echo $_SESSION['acc_id']" />
<input type="text" name="acc3" value="<?php echo $_SESSION['acc_cat']" />
<input type="submit" name="submit">
<?php } ?>

ajax comment form not posting data to mysql

I am using ajax to post a comment to a mysql table. When I post the comment, the javascript is loading but it doesnt submit the data to the mysql database.
$(document).ready(function(){
$('#commentform').on('submit',function(e) {
$.ajax({
url:'ajax.php',
data:$(this).serialize(),
type:'POST',
success:function(data){
console.log(data);
$("#success").show().fadeOut(5000);
},
error:function(data){
$("#error").show().fadeOut(5000);
}
});
e.preventDefault();
});
});
ajax.php
$id = $_POST['id'];
$comment = $_POST['comment'];
$username = $_POST['username'];
$array = $pdo->prepare("INSERT INTO `comments` (id, comment, user)
VALUES (:id,:comment,:username);");
$array->execute(array(':id' => $id, ':comment' => $comment, ':username' => $username));
html
<form method="post" name="commentform" id="commentform">
<textarea name="comment" name="comment"></textarea><br>
<input type="hidden" value="<?php echo "$id"; ?>" name="id" id="id" />
<input type="hidden" value="<?php echo "$username"; ?>" name="username" id="username" />
<input type="submit" name="submit" id="submit" value="REPLY" />
</form>

You have issue in html form, you have used multiple " around php variables which causes to break the value attribute, use updated html
HTML
<form method="post" name="commentform" id="commentform">
<textarea name="comment" name="comment">test comment</textarea><br>
<input type="hidden" value="<?php echo $id; ?>" name="id" id="id" />
<input type="hidden" value="<?php echo $username; ?>" name="username" id="username" />
<input type="submit" name="submit" id="submit" value="REPLY" />
</form>
Ajax script is fine
here is fiddle which is making ajax request fine
ajax.php looks fine as well
$id = $_POST['id'];
$comment = $_POST['comment'];
$username = $_POST['username'];
$array = $pdo->prepare("INSERT INTO `comments`
(id, comment, user)
VALUES
(:id, :comment, :username)"
);
$array->execute(array(
':id' => $id,
':comment' => $comment,
':username' => $username));
