Session variable not being set in the first time - php

Question

My modal for asking name
<?php session_start(); ?>
<div class="modal name fade modal-scrollable" id="name" role="dialog" aria-labelledby="basicModal" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title myModalLabel">Your name!</h4>
</div>
<div class="modal-body">
<form id="nameForm" action="index.php" method="post">
<div class="form-group">
<label class="col-xs-3 control-label">Your name : </label>
<div class="col-xs-4">
<input type="text" class="form-control name" name="name" required/>
</div>
</div></div><br/><br/>
<div class="modal-footer">
<button type="submit" class="btn btn-primary" id="ok">Ok</button>
</div>
</form>
</div>
</div>
</div>
Script code
<?php
if(!$_SESSION['user']['name']){
echo "<script>
$(window).load(function(){
$('#name').modal({
backdrop: 'static',
keyboard: true
})
$('#name').modal('show');
});
</script>";
}
?>
<script>
$('#ok').submit(function(){
<?php
$_SESSION['user']['name']=$_POST['name'];
print"location.reload();";
?>
});
</script>
This code actually works fine. The code is that on page load it will ask the name of user and set the session variable to set the entered name. It will open the modal only if session variable is not set. But in reality the user has to enter his name twice.I even tried reload() but it didnt work. Please help!

Answer 1

Your session is being set correctly. However, you are not initializing the session. The first line after your <?php tag should be:
session_start();
Please, also note that in this part of your code, you should print your JavaScript code:
<?php
$_SESSION['user']['name']=$_POST['name'];
print "location.reload();";
?>
