<p>1. Using Validation error with old values:</p>
<form action="<?php echo URL?>demo/save" method="post">
<?php echo csrf_field();?>
Name:<br>
<input type="text" name="name" value="<?php echo old('name');?>">
<?php if(isset($errors['name'])):?>
<span class="text-danger"><?php echo $errors['name'][0]; ?></span>
<?php endif;?> <br />
First name:<br>
<input type="text" name="firstname" value="<?php echo old('firstname');?>">
<?php if(isset($errors['firstname'])):?>
<span class="text-danger"><?php echo $errors['firstname'][0]; ?></span>
<?php endif;?> <br />
<input type="submit" value="Submit">
</form>
<hr />
<p>2. Using Session:</p>
<?php
//session set with array
$session = [
'name' => 'Kabir',
'age' => 30,
'logged_in' => true
];
session($session);
//session data read through key
echo " name:".session('name');
echo " name:".session_get('name');
//session data remove through key
echo " forget name:".session_forget('name');
echo " age: ".session('age',null);
//session data set through key
echo " age: ".session('age',null);
echo " age: ".session_put('age',45);
//echo " session destroy all:".var_dump(session_empty());
echo " session all:".var_dump(session_all());
?>
<hr>
<p>2. Using CSRF:</p>
<?php
echo " Form csrf hidden method with token: csrf_field()"; echo '<br />';
echo " csrf token on session: session('token')";
?>
<hr />
