Show Signup modal window then Login modal right away

I have a nav bar with options for signup or login. Once clicked on either it will display a modal window using Bootstrap. What I am trying to do is that when the user is finished with the join modal window (pressed submit button and submitted data to the controller), I want to show the signin modal window right after. Show my idea was when submitting the form data to the controller. The controller would respond back with a display-type equaling "join, signin, nothing" and reinclude the page. In the page it will check what the display-type is then will call either show_join_modal() function if the display-type is signup or call either show_signin_modal() function if the display-type is login.
My idea using JQuery was something like this, Here is code in the startpage.php
<script>
<?php
if (isset($display_type))
if ($display_type == 'signin')
echo 'show_signin_modal();';
else if ($display_type == 'join')
echo 'show_join_modal();';
else
;
?>
function show_signin_modal() {
$("#signinModal").modal("show");
}
function show_join_modal() {
$("#joinModal").modal("show");
}
function hide_all_modal() {
$("#joinModal").modal("hide");
$("#signinModal").modal("hide");
}
</script>

However, I could not get it to work.
Any ideas. Any sample code? Thanks in advance!

Replace this code with the current on your controller.
<script>
function show_login_modal() {
$("#loginModal").modal("show");
}
function show_signup_modal() {
$("#signupModal").modal("show");
}
function hide_all_modal() {
$("#signupModal").modal("hide");
$("#loginModal").modal("hide");
}
</script>
<?php
if (isset($display_type))
if ($display_type == 'signin')
echo '<script type="text/javascript">show_signin_modal();</script>';
else if ($display_type == 'join')
echo '<script type="text/javascript">show_join_modal();</script>';
//echo 'show_join_modal();';
else
;
?>

I found out how to do it with help from "https://codepen.io/elmahdim/details/azVNbN" which he posted on "Bootstrap modal: close current, open new" under username "Mahmoud". So in order to go from the joinModal window to the signinModal window right after the user submits the form on the joinModal window. I updated the submit button in the joinModal window with:
<button type="submit" class="btn btn-default" data-toggle="modal" data-target="#signinModal" data-dismiss="modal">Submit</button>

Post modal form values to a PHP file

I have a form in a modal. When I press the submit button the php file runs with the following errors:
Notice: Undefined index: phone1 in C:\xampp\htdocs\site\bank.php on line 2
Notice: Undefined index: charge1 in C:\xampp\htdocs\site\bank.php on line 4
Here is the PHP code in bank.php:
<?php
echo $_POST["phone"];
echo "</br>";
echo $_POST["charge"];
?>
Here is the modal contents:
<!-- Modal content-->
<div class="modal fade" id="register" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal title here</h4>
</div>
<div class="modal-body">
<form id="modal-form" class="form-horizontal" method="POST" action="bank.php">
<div class="form-group col-md-12">
<div class="form-group">
<div class="col-xs-6" style="float:right;">
<label>phone numer:</label>
<input id="phone" type="text" class="form-control" name="phone" value="pre filled value" disabled/>
<span id='display'></span>
</div>
<div class="col-xs-6" style="float:left;">
<label>charge:</label>
<input style="font-size:17px; font-weight:bold;" id="charge" type="text" class="form-control" name="charge" value="some other prefilled value" disabled/>
</div>
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<button class="btn btn-danger btn-default pull-right" data- dismiss="modal" style="margin-left:10px;">close</button>
<button type="submit" class="btn btn-success"> submit </button>
</div>
</div>
</form>
</div>
<div class="modal-footer">
modal footer
</div>
</div>
</div>
</div>
I would be thankful if some one help me figure out what;s wrong with this

Not relevant anymore, OP edited his question. see edit for relevant answer!
the name of the post variable is defined by the nameattribute of the input, not the id.
therefore in your bank.php you will have $_POST['phone1'] and $_POST['charge1']available.
you can always just var_dump($_POST); to see all available post variables.
Edit: Also, disabled inputs are not being sent on submit. You can work around that fact by just adding a second hidden input for each disabled one like that:
<!-- Modal content-->
<div class="modal fade" id="register" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal title here</h4>
</div>
<div class="modal-body">
<form id="modal-form" class="form-horizontal" method="POST" action="bank.php">
<div class="form-group col-md-12">
<div class="form-group">
<div class="col-xs-6" style="float:right;">
<label>phone numer:</label>
<input id="phoneDisabled" type="text" class="form-control" name="phoneDisabled" value="pre filled value" disabled/>
<input id="phone" type="hidden" class="form-control" name="phone" value="pre filled value" disabled/>
<span id='display'></span>
</div>
<div class="col-xs-6" style="float:left;">
<label>charge:</label>
<input style="font-size:17px; font-weight:bold;" id="chargeDisabled" type="text" class="form-control" name="chargeDisabled" value="some other prefilled value" disabled/>
<input style="font-size:17px; font-weight:bold;" id="charge" type="hidden" class="form-control" name="charge" value="some other prefilled value" disabled/>
</div>
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<button class="btn btn-danger btn-default pull-right" data- dismiss="modal" style="margin-left:10px;">close</button>
<button type="submit" class="btn btn-success"> submit </button>
</div>
</div>
</form>
</div>
<div class="modal-footer">
modal footer
</div>
</div>
</div>
</div>
Edit2: Or, just change disabled attribute to readonly

The name in your $_POST variable and the html input name are both different. Please try to make them the same and hopefully, your code will work.
Change name=phone1 to name=phone or whatever.

You have set both of those inputs as disabled. Forms by default won't post those. You probably need to grab the vars with JavaScript, or remove the disabled attributes, again, with JavaScript.

JavaScript Pop-Up Dialog Not Being Read by Web Accessibility Screen Reader

I have a project requirement in which the web page I am building in question needs to be read by the JAWS screen reading software, but the client only has access to JAWS 11 as their latest version.
We currently have JavaScript-based pop-up dialogs for many of the forms on the web and right now a big problem is that the JAWS 11 software cannot read the below pop-up text. What is wrong with the pop-up dialog below (in HTML)?

Setting the main content to aria-hidden='true' tells the screen reader to stop reading the content there.
Try using aria-hidden='false'

How are you opening the modal? Because with a tabindex of -1 on the wrapper div, you will only be able to send the screenreader and keyboard focus to the modal via JavaScript. In that case it's best to make moving the focus part of the script which opens the modal.
On the other hand, if it's opened via a link, you can just remove that tabindex attribute altogether and put the id of the wrapper div in the link href, e.g. <a href=#EditContentModal>
Either way, remember to send focus back to where it started when the modal is closed.
Edited to clarify: the tabindex="-1" attribute on your wrapper div is preventing keyboard access. Remove it. See MDN's tabindex reference: a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation.

i have created this modal file as a separate file and included in my main php file where table of registered members is printed.

Location requires an absolute path. Check the second to last note in the Notes section.
http://php.net/manual/en/function.header.php
When you manually refresh the page you are just resending the form data that was submitted which is why you get two entries in the DB.

Passing parameters from input

How can I append a URL with an email address that a user inputs, and then submits this email address via button? I am using a modal that will pop up, ask for the email, and then call the url when the user hits the submit button. (jQuery is supported) Any help is much appreciated! Thanks
<div id="emailModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel"> We Can Help</h3>
</div>
<div class="modal-body">
<h6> Enter your information in the fields below to reset a forgotten password, or to restore access to an account that has been locked for security </h6>
<br>
<form >
<input type="text" class="input-block-level" placeholder="Email address">
<!-- <input type="password" class="input-block-level" placeholder="Password">
<label class="checkbox">
<a href="#"><input type="checkbox" value="remember-me"> Remember me
</label></a> -->
</form>
</div>
<div class="modal-footer">
<button class="m-btn blue" data-dismiss="modal">Submit</button>
</div>
</div>

You can do something like
$("#emailModal .m-btn").click(function(){
$.post("/my/url?email=" + $("#emailModal input.input-block-level").val(), function(){
// this function is called on POST finish.
});
return false;
});
I think this is what you are after.

Change the form to this...
<form action="some-url.php" method="get">
<input type="text" name="email" class="input-block-level" placeholder="Email address">
</form>
and add this script...
$("#emailModal button").on("click", function() {
$("#emailModal form").submit();
});
