Display a bootstrap dynamic modal - php

Question

I am trying to display a modal when pressing the button "Vezi rezolvare"
I have the following code for the button:
<div class="col-md-4 text-center patrat-block">
<div class="thumbnail">
<img class="img-responsive" src="img/LogoProbleme/pg1logo-v2.jpg" alt="">
<div class="caption">
<h3>Problema 1<br>
<small>Gradina</small>
</h3>
<p>Află dimensiunile grădinii</p>
<ul class="list-inline">
<li>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#Problema"><span class="glyphicon glyphicon-pencil"></span> Vezi Rezolvare </button>
</li>
</ul>
</div>
</div>
</div>
And the modal content + php :
<?php
if(isset($_GET['id'])&&isset($_GET['category']))
{
$id=$_GET['id'];
$category=$_GET['category'];
$sql = "SELECT cerinta, rezolvare FROM probleme WHERE id='".$id."'AND category='".$category."'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc())
{
$cerinta=$row["cerinta"];
$rezolvare=$row["rezolvare"];
}
$_SESSION["cerinta"]=$cerinta;
$_SESSION["rezolvare"]=$rezolvare;
}
}
?>
<div id="Problema" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Problema</h4>
</div>
<div class="modal-body">
<h4>Cerinta</h4>
<div class="well">
<?php echo $cerinta;?>
</div>
<h4>Rezolvare</h4>
<div class="well">
<?php echo $rezolvare;?>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Inchide fereastra</button>
</div>
</div>
</div>
</div>
What this is trying to accomplish is to show a modal with some information in my database. I checked and the values are stored successfully in $cerinta and $rezolvare.
It seems like when the button is pressed, there is a fast fade and I am redirected to the top of the page, without showing the modal. I put an <a href="probleme.php?id=1&category=g"> so I know what button has been pressed, but it seems like it refreshes the page and the modal isn't displayed. How can I let the modal be displayed?

Nesting a <button> inside an achor <a> is not valid html syntax because it can't tell which one was clicked. Also the anchor has an href different than '#' so it's just redirecting you to probleme.php?id=1&category=g. You can modify your code as follows (not tested):
Remove the button from inside the anchor and change the anchor to:
<a href="probleme.php?id=1&category=g" class="btn btn-primary"
data-toggle="modal" data-target="#Problema">
<span class="glyphicon glyphicon-pencil"></span> Vezi Rezolvare
</a>
Have the template of the modal somewhere in your html:
<div id="Problema" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Problema</h4>
</div>
<div class="modal-body">
Some fine body
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">
Inchide fereastra
</button>
</div>
</div>
</div>
</div>
Modify your php to return only the body of the modal:
<?php
// Some good php
echo("
<h4>Cerinta</h4>
<div class=\"well\">
{$cerinta)}
</div>
<h4>Rezolvare</h4>
<div class=\"well\">
{$rezolvare}
</div>");
// The modal body is returned by php
?>
Use ajax to retrieve the modal body and subsequently open the modal. Something in the lines of:
$(document).ready(function() {
// Assign some id to the anchor say id="myAnchor"
$('#myAnchor1').click(function(e) {
e.preventDefault();
// get the modal
var modal = $($(this).data("data-target"));
var url = $(this).attr("href");
var request = $.get(url);
request.done(function(response) {
// get modal
modal.find(".modal-body").html(response);
modal.modal("show");
});
});
});
