How to pass $_GET variables from a link to a bootstrapmodal?

Question 1

Snippet from my HTML code.

<td><span data-placement="top" data-toggle="tooltip" title="Show"><a href="#" class="btn btn-primary btn-xs" data-toggle="modal" data-target="#editBox" data-book-id="<?php echo $obj->id;?>"><span class="glyphicon glyphicon-pencil"></span></a></span></td>

The modual that are beeing opened when link is clicked:

<!-- Modal -->
    <div class="modal fade" id="editBox" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
            <h4 class="modal-title" id="myModalLabel">Modal title</h4>
          </div>
          <div class="modal-body">
            <?php var_dump($_GET)?>
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
          </div>
        </div>
      </div>
    </div>

Is there a proper way to pass my id into the modal?

Question 2

The simple solution to pass id, fetch records from database against passed id and show in modal is;

Simple Solution

Modal Call button

<td><span data-placement="top" data-toggle="tooltip" title="Show"><a class="btn btn-primary btn-xs" data-toggle="modal" data-target="#editBox" href="file.php?id=<?php echo $obj->id;?>"><span class="glyphicon glyphicon-pencil"></span></a></span></td>

Modal HTML

Put following modal HTML outside the while loop in page where the above call button is located (preferable at bottom of page)

<div class="modal fade" id="editBox" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
          //Content Will show Here
        </div>
    </div>
</div>

Now Create a PHP file and name it file.php

This file is called with modal call button href="file.php?id=<?php echo $obj->id;?>"

<?php
//Include database connection here
$Id = $_GET["id"]; //escape the string if you like
// Run the Query
?>
<div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h4 class="modal-title"><center>Heading</center></h4>
</div>
<div class="modal-body">
    //Show records fetched from database against $Id
</div>
<div class="modal-footer">
    <button type="button" class="btn btn-default">Submit</button>
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>

To remove the data inside modal or in other words to refresh the modal when open next records without page refresh, use following script

Put it after jQuery and Bootstrap library (Remember jQuery & Bootstrap libraries always come first)

<script>
$( document ).ready(function() {
    $('#editBox').on('hidden.bs.modal', function () {
          $(this).removeData('bs.modal');
    });
});
</script>

Alternate Solution with Ajax and Bootstrap Modal Event Listener

In Modal Call button replace href="file.php?id=<?php echo $obj->id;?> with data attribute data-id="<?php echo $obj->id;?>" so we pass the id of row to modal using bootstrap modal event

<td><span data-placement="top" data-toggle="tooltip" title="Show"><a class="btn btn-primary btn-xs" data-toggle="modal" data-target="#editBox" data-id="<?php echo $obj->id;?>"><span class="glyphicon glyphicon-pencil"></span></a></span></td>

Modal HTML

Put following modal HTML outside the while loop in page where the above call button is located (preferable at bottom of page)

<div class="modal fade" id="editBox" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title"><center>Heading</center></h4>
            </div>
            <div class="modal-body">
                <div class="form-data"></div> //Here Will show the Data
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default">Submit</button>
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

Now Add following script in same page;

<script>
//jQuery Library Comes First
//Bootstrap Library
$( document ).ready(function() {       
    $('#myModal').on('show.bs.modal', function (e) { //Modal Event
        var id = $(e.relatedTarget).data('id'); //Fetch id from modal trigger button
    $.ajax({
      type : 'post',
       url : 'file.php', //Here you will fetch records 
      data :  'post_id='+ id, //Pass $id
      success : function(data){
         $('.form-data').html(data);//Show fetched data from database
       }
    });
    });
});
</script>

Now Create a PHP file and name it file.php (same as use in Ajax Method)

<?php
//Include database connection here
if($_POST['id']) {
    $id = $_POST['id'];
    // Run the Query
    // Fetch Records
    // Echo the data you want to show in modal
 }
?>

In this solution, you don't need following script to remove the data inside modal or in other words to refresh the modal

$('#editBox').on('hidden.bs.modal', function () {
      $(this).removeData('bs.modal');
});

Alternate Solution with Ajax and jQuery Click function

Modal Call button

<td><span data-placement="top" data-toggle="tooltip" title="Show"><a class="btn btn-primary btn-xs" class="open-modal" href="" id="<?php echo $obj->id;?>"><span class="glyphicon glyphicon-pencil"></span></a></span></td>

Put following modal HTML in page where above modal call button located (preferable at bottom of page)

<div class="modal fade" id="editBox" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title" id="myModalLabel">Modal title</h4>
            </div>
            <div class="modal-body">
                <div class="form-data"></div> //Here Will show the Data
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

following Ajax method code in same page where Modal HTML & Modal call button located.

<script>
//jQuery Library Comes First
//Bootstrap Library
$( document ).ready(function() { 
  $('.open-modal').click(function(){
    var id = $(this).attr('id');
    $.ajax({
      type : 'post',
       url : 'file.php', //Here you should run query to fetch records
      data : 'post_id='+ id, //Here pass id via 
      success : function(data){
          $('#editBox').show('show'); //Show Modal
          $('.form-data').html(data); //Show Data
       }
    });
  });
});
</script>

And the PHP file file.php will be same as the above solution with bootstrap modal event

Pass On page information to Modal

In some cases, only need to pass (display) minimal information to modal which already available on page, can be done with just bootstrap modal event without Ajax Method with data-attributes

<td>
  <span data-placement="top" data-toggle="tooltip" title="Show">
    <a data-book-id="<?php echo $obj->id;?>" data-name="<?php echo $obj->name;?>" data-email="<?php echo $obj->email;?>" class="btn btn-primary btn-xs" data-toggle="modal" data-target="#editBox">
    <span class="glyphicon glyphicon-pencil"></span>
    </a>
  </span>
</td>

Modal Event

$(document).ready(function(){
    $('#editBox').on('show.bs.modal', function (e) {
        var bookid = $(e.relatedTarget).data('book-id');
        var name = $(e.relatedTarget).data('name');
        var email = $(e.relatedTarget).data('email');
        //Can pass as many onpage values or information to modal  
     });
});

Question 3

<button type='button' data-a="<?echo $fila['idPlaza'];?>" href='#editarUsuario' class='modalEditarUsuario btn btn-warning btn-xs' data-toggle='modal' data-backdrop='static' data-keyboard='false' title='Editar usuario'>
    <img src='../images/edit.png' width='20px' height='20px'>
</button>

Put below code in footer before end of </body> tag.

<!-- MODAL EDITAR-->
<div id="editarUsuario" class="modal fade modal" role="dialog">
    <div class="vertical-alignment-helper">
        <div class="modal-dialog vertical-align-center">
        <div class="modal-content">


        </div>
        </div>
    </div>
</div>

Use Script like this.

<script>
    $('.modalEditarUsuario').click(function(){
        var ID=$(this).attr('data-a');
        $.ajax({url:"NewPage.php?ID="+ID,cache:false,success:function(result){
            $(".modal-content").html(result);
        }});
    });
</script>

Create NewPage.php, and paste the below code. (Remember, this page name NewPage.php is used in script tag also. if you are planning to change the name of this page, change page name there in script tag too. Both are related.)

<?
$ID=$_GET['ID'];
?>
<div class="modal-header">
   <button type="button" class="close" data-dismiss="modal">&times;</button>
   <h2 class="modal-title">Editar usuario</h2>
</div>
<form name="formularioModificaUsuario" method='post' action="usuarios.php">
    <div class="modal-body">
        <input type="text" class="form-control" name="idPlaza" id="a">
        <?php 
            $valueA = $ID;
        ?>
    </div>
    <div class="modal-footer">
        <button type="reset" id="cancelar" class="btn btn-danger" data-dismiss="modal" value="reset">
        <img src='../images/cancel.png' width='20px' height='20px'> Cancelar</button>
        <button type="submit" name="submitModifica" id="submit" class="btn btn-primary" value="submit">
        <img src='../images/save_changes.png' width='20px' height='20px'> Guardar cambios</button>
    </div>
</form>

Question 4

A more updated answer is found below: https://.com/a/44391959/1004312

You are opening a modal from another modal and closing the first. If you're using Bootstrap 3, you can do the following:

DEMO: http://jsbin.com/venek/1/edit

In the first modal put the link to the next modal (#modal-1 & #modal-2 are example ids)

  <a href="#modal-2" data-toggle="modal" data-dismiss="modal">Next</a>

In the second modal put the link to the first:

  <a href="#modal-1" data-toggle="modal" data-dismiss="modal">Previous</a>

Question 5

Problem here is with reference.

When you create new object in code behind, new object will be created and this is not the same object which you have in xaml code. So you should use following code:

<local:GroupsItems x:Name="myGroupsItems"/>

and in code behind you don't have to create new object. You should use object that you added in XAML:

...
myGroupsItems.MyParent = this;
myGroupsItems.passedv(e.ToString(), this);
...

Here is example solution (sampleproject).

Question 6

Use from django.conf import settings but mind that settings is not a module. The documentation clearly explains that and your use case.
