div #id in foreach loop only selects last variable when trying to show/hide in function

I am navigating through a simple foreach loop to get "blog posts". It shows basic blog information, a reply and delete button. When I select the 'reply' button, a small form beneath the reply button appears to fill out. The problem is, the function I am passing the variable to, only gets the last id for the form. How do I change my function or div element to be unique for each instance?
I have tried setting up PHP #echo variable's on the "id" and function, I have checked all my opening and closing brackets 10-fold. I have tried using different GetElementBy ... methods. I started looking into Jquery but I wanted to get this finished with PHP/Javascript only.
<?php foreach ($mainentries as $entry) :
$subentryID = $entry['SubEntryID'];
if ($subentryID == "0")
{ ?>
<div><tr><td><?php echo ('#'.$entry['EntryID'].' - ')?></td>
<td><?php echo $entry['Body']; ?></td>
<br />
<?php foreach($subentries as $subentry) : ?>
<?php if ($subentry['SubEntryID'] == $entry['EntryID'])
{ ?>
<div id="subposts">
<td><td><td>#<?php echo $subentry['EntryID'];?></td><br>
<td>
<?php echo $subentry['Body']; ?>
</td></td></td>
</div>
<?php } endforeach; ?>
<br />
<td>
<button onclick="cookiechecksub()">Reply</button>
<?php echo $entry['EntryID'];
$subform = $entry['EntryID']; ?>
<div id="<?php echo $subform?>" style="display:none">
<form action="Add_subentry.php" method="post" id="Add_subentry">
<label>Title:</label><br />
<input type = "text" name="Title" class="Title"/> <br />
<label>Body</label><br />
<div class="area">
<input type = "textarea" name="Body" class="Body"/><br />
</div>
<input type="hidden" readonly="true" name="EntryID" value="<?php echo $entry['EntryID']; ?>" />
<input type=submit id="btnReply" value="Submit Reply"/>
</form>
</div></td>
<td>
<form action="Delete_entry.php" method="post" id="Delete_entry">
<input type="hidden" readonly="true" name="EntryID" value="<?php echo $entry['EntryID']; ?>" />
<?php if ($userid == 1)
{ ?>
<input type="submit" id="btnDelete" value="Delete Post"/>
<?php } ?>
<br /><br />
</form>
</td>
</tr>
</div>
<?php
} endforeach; ?>
<Script>
function cookiechecksub() {
if (!userid) {
if (confirm("Please log in first")) {
window.location.replace("http://localhost/alexdes/login-logout.php");
}
}
else {
TryAddSubPost();
}
}
function TryAddSubPost()
{
var x = document.getElementById("<?php echo $subform?>");
if (x.style.display === "none")
{
x.style.display="block";
}
else
{
x.style.display="none";
}
}
</Script>

this is because you used php echo in the js function especially in TryAddSubPost
change it to be like this:
<script>
function cookiechecksub(id) {
if (!userid) {
if (confirm("Please log in first")) {
window.location.replace("http://localhost/alexdes/login-logout.php");
}
}
else {
TryAddSubPost(id);
}
}
function TryAddSubPost(id)
{
var x = document.getElementById(id);
if (x.style.display === "none")
{
x.style.display="block";
}
else
{
x.style.display="none";
}
}
</script>
and use the id from php only when calling the function, like this:
<button onclick="cookiechecksub('<?php echo $entry['EntryID']?>')">Reply</button>

Give cookiechecksub an argument, and pass it to TryAddSubPost
<button onclick="cookiechecksub('<?=$entry['EntryID']?>')">

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.

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">

<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; ?>"/>

Email input is not taking email address as valid input in newsletter subscribe box

I have newsletter subscribe input in opencart website and when i input email and press subscribe it says "Email is not valid!: even thou it is.
So i cant use it since it doesnt take emails.
I used this theme and didnt change anything in the subscribe module,
you can scroll down to the footer and check how it behaves here: http://demopavothemes.com/pav_woosa/demo2/
Cant figure out what is the problem.
Heres the code of the module:
<div class="<?php echo $prefix; ?> newsletter-v1" id="newsletter_<?php echo $position.$module;?>">
<form id="formNewLestter" method="post" action="<?php echo $action; ?>" class="formNewLestter">
<div class="panel panel-v1">
<div class="panel-heading">
<h4 class="panel-title"><?php echo $objlang->get("entry_newsletter");?></h4>
</div>
<div class="panel-body">
<div class="input-group">
<input type="text" placeholder="Email Here ..." class="form-control email" <?php if(!isset($customer_email)): ?> <?php endif; ?> size="18" name="email">
<div class="input-group-btn pull-left">
<button type="submit" name="submitNewsletter" class="btn btn-primary icon-mail radius-6x"><?php echo $objlang->get("button_subscribe");?></button>
</div>
</div>
<input type="hidden" value="1" name="action">
<div class="valid space-top-10"></div>
</div>
<?php if (!empty($social)): ?>
<?php echo html_entity_decode( $social );?>
<?php endif ?>
</div>
</form>
</div>
<script type="text/javascript"><!--
$( document ).ready(function() {
var id = 'newsletter_<?php echo $position.$module;?>';
$('#'+id+' .box-heading').bind('click', function(){
$('#'+id).toggleClass('active');
});
$('#formNewLestter').on('submit', function() {
var email = $('.inputNew').val();
$(".success_inline, .warning_inline, .error").remove();
if(!isValidEmailAddress(email)) {
$('.valid').html("<div class=\"error alert alert-danger\"><?php echo $objlang->get('valid_email'); ?><button type=\"button\" class=\"close\" data-dismiss=\"alert\">×</button></div></div>");
$('.inputNew').focus();
return false;
}
var url = "<?php echo $action; ?>";
$.ajax({
type: "post",
url: url,
data: $("#formNewLestter").serialize(),
dataType: 'json',
success: function(json)
{
$(".success_inline, .warning_inline, .error").remove();
if (json['error']) {
$('.valid').html("<div class=\"warning_inline alert alert-danger\">"+json['error']+"<button type=\"button\" class=\"close\" data-dismiss=\"alert\">×</button></div>");
}
if (json['success']) {
$('.valid').html("<div class=\"success_inline alert alert-success\">"+json['success']+"<button type=\"button\" class=\"close\" data-dismiss=\"alert\">×</button></div>");

function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(#((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(#\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i);
return pattern.test(emailAddress);
}
--></script>

This line:
$('.inputNew')
is looking for a class named inputNew. Your HTML doesn't have an element with that name. Your element it looks like has a class of email.
<input type="text" placeholder="Email Here ..." class="form-control email" <?php if(!isset($customer_email)): ?> <?php endif; ?> size="18" name="email">
^^^^^
You also could use the form-control but that doesn't sound unique. An id would be better or you could use the name attribute like this:
$('input[name="email"]')
so change the JS line to:
var email = $('.email').val();
or
var email = $('input[name="email"]').val();

Hide/Show toggle echo results in php

I am trying to toggle results i have echo'd out of table but i am having no luck.
I have tried the same code in HTML and it works perfectly.
Ive been working on this for a while now, and was wondering if someone could point me in the right direction.
What I've tired
Adding the javascript inside the php echo.
Adding a counter to the id, to make it unique on loop
Placing each line of the echo results in echo(""); tags.
adding a counter, to make the id unique on loop.
PHP
$i = 1;
while ($output = $fc_sel->fetch_assoc()) {
$fc_run .= $output['Food_Cat_name'] . $output['Food_Cat_Desc'] . '<br>';
$_SESSION['Food_Cat_name'] = $output['Food_Cat_name']; //echo out product name
$_SESSION['Food_Cat_Desc'] = $output['Food_Cat_Desc']; //echo out product desc
echo"
<div id='first_product'>
<button onclick='toggle_visibility('tog')'>Toggle</button>
<div id='tog'>
<div id='red_head'>
<p id='menu_title' class ='hidden' onclick='toggle_visibility('tog')'> Add your first menu item</p>
</div>
<h3 id='menu'>Menu Section</h3>
<form name='first_prod' id='first_prod' enctype='multipart/form-data' action='testing.php' method='POST' accept-charset='utf-8' >
<label id='cat_label' name='cat_label'>Name</label>
<input type='text' id='cat_name' name='cat_name' value=''>
<label id='desc_label' name='desc_label'>Description</label>
<input type='text' id='cat_desc' name='cat_desc' value=''>
</form>
</div>
</div>
";
}
}
JAVASCRIPT
<script>
//turn entire div into toggle
function toggle_visibility(id) {
var e = document.getElementById(id);
if (e.style.display == 'block' || e.style.display == '')
e.style.display = 'none';
else
e.style.display = 'block';
}
</script>

The single quotes in onclick='toggle_visibility('tog')' are conflicting with the outer single quotes. So either escape them or use double quotes in either the outer pair or the inner pair.
Then in PHP, remove the <?php echo. Just put the HTML in PHP. The echo only complicates things. If you need dynamic data in your HTML, just inject it at that place with <?php ... ?>. But so far I haven't seen any of that in your HTML: it is static.
Here is a working snippet, after having made that change in two places:
//turn entire div into toggle
function toggle_visibility(id) {
var e = document.getElementById(id);
if (e.style.display == 'block' || e.style.display == '')
e.style.display = 'none';
else
e.style.display = 'block';
}
<div id='first_product'>
<button onclick="toggle_visibility('tog')">Toggle</button>
<div id='tog'>
<div id='red_head'>
<p id='menu_title' class ='hidden' onclick="toggle_visibility('tog')"> Add your first menu item</p>
</div>
<h3 id='menu'>Menu Section</h3>
<form name='first_prod' id='first_prod' enctype='multipart/form-data' action='testing.php' method='POST' accept-charset='utf-8' >
<label id='cat_label' name='cat_label'>Name</label>
<input type='text' id='cat_name' name='cat_name' value=''>
<label id='desc_label' name='desc_label'>Description</label>
<input type='text' id='cat_desc' name='cat_desc' value=''>
</form>
</div>
</div>
Edit after modification of the question
The code in the question was extended so the HTML is produced in a loop now.
You should now take care to produce unique id values only. So you'll probably want to add <?=$i?> at several places, like this:
<?php
session_start();
// ....
$i = 1;
while ($output = $fc_sel->fetch_assoc()) {
$fc_run .= $output['Food_Cat_name'] . $output['Food_Cat_Desc'] . '<br>';
$_SESSION['Food_Cat_name'] = $output['Food_Cat_name'];
$_SESSION['Food_Cat_Desc'] = $output['Food_Cat_Desc'];
?>
<div id='first_product<?=$i>'>
<button onclick="toggle_visibility('tog<?=$i>')">Toggle</button>
<div id='tog<?=$i>'>
<div id='red_head<?=$i>'>
...etc. Note that the PHP was closed before the HTML output started. Do this, instead of a large echo. Then at the end of it, open PHP tag again to end the loop:
<?php
}
?>

please modify your code
echo "
<div id='first_product'>
<button onclick='toggle_visibility(\"tog\")'>Toggle</button>
<div id='tog'>
<div id='red_head'>
<p id='menu_title' class ='hidden' onclick='toggle_visibility(\"tog\")'> Add your first menu item</p>
</div>
<h3 id='menu'>Menu Section</h3>
<form name='first_prod' id='first_prod' enctype='multipart/form-data' action='testing.php' method='POST' accept-charset='utf-8' >
<label id='cat_label' name='cat_label'>Name</label>
<input type='text' id='cat_name' name='cat_name' value=''>
<label id='desc_label' name='desc_label'>Description</label>
<input type='text' id='cat_desc' name='cat_desc' value=''>
</form>
</div>
</div>
"

<button value='tog' onclick='toggle_visibility(this)'>Toggle</button>
Just use "this" and assign value to button its working

Try this ;)
<?php
$i = 1;
while($output = $fc_sel->fetch_assoc()){
$fc_run .= $output['Food_Cat_name'] . $output['Food_Cat_Desc'] . '<br>';

I create array named 'content' in javascript and then need to stuff almost an entire form into it to be able to create a child row in DataTables.
( for more information regarding what I've been trying to do and where these variables come from, see Datatables child row with PHP data from Codeigniter )
I've tried escaping single and double quotes (PHP complains about this), json_encode (PHP also complains about this as I still need the quotes and PHP interprets the quotes as the end of the json_encode), I've tried surrounding the entire value of the javascript array with '"' and "'", I've tried surrounding every line with ' '+ without success as well. How do I get this entire string into a form where javascript and PHP will parse it correctly and neither of them freak out?

Look at what you're doing:
<script>
var content = [];
content[<?php [..snip..] ?>] = "<?php [..snip..] ?>
^---start of javascript string
<div class="panel-body">
^---end of javascript string
^---start of another string
That means you have essentially:
variable = "some string stuff"variable-variable"more string stuff"
which is outright illegal JS.
The specific fix is to ESCAPE all of the strings in that html:
<script>
yadayada
<div class=\"panel-body\"> yada yadayada
^-----------^
But that doesn't fix the fact that this is incredibly bad code. You shouldn't be dumping loads of html into a JS string, and you should never be directly echoing text from PHP into a JS context.
If nothing else, why not generate all the content in PHP, then dump it all out as json?
<?php
$data = "blah blah blah blah";
?>
<script>
var content = <?php echo json_encode($data); ?>;
