In cakephp 3 I tried to set cookie in my controller using write cookie method. Error got invalid key for decrypt(), key must be at least 256 bits (32 bytes) long – used following line of code.

$this->Cookie->write(‘username’, ‘test’, true, ‘1 year’);

I got following error after execting page.
Invalid key for decrypt(), key must be at least 256 bits (32 bytes) long

Before using cookie write method, I loaded cookie component in appcontroller using following line.
$this->loadComponent(‘Cookie’);

I loaded conponnet in initialize method (appcontroller.php)

After searching I found following solution. I changed app.php file and added following line of code

'Security' => [
        'salt' => '123456789purab@eparinay!@#*$($(',
    ]

Above solution worked for me and it solved issue.

If you are getting this error means your Security.salt in app.php does not have the correct length.

I am using cakephp 3.1 for development one of my portal. While configuring email Igot undefined index getOriginalSubject in DebugkitTransport.php. I searched for some time on net for solution but I did not find any solution. This function tries to get subject from email obejct. I think this is bug in cakephp 3.1.

My solution is as follows. I opened DebugkitTransport.php file and in send function I changed following line

/fixing issue of $email->getOriginalSubject undefined index
$headers['Subject'] = $email->subject();

Above line fixed my issue and I am able to send email now. I using smtp setting for sending email. I am using following code for one of my site called http://eparinay.com

$email = new Email();
$email->transport('eparinay');
try {
$email->template('eparinay')
->emailFormat('html')
->to($email)
->bcc('purabdk@yahoo.co.in')
->from(['noreply@eparinay.com' => 'eParinay.com'])
->viewVars(array('username' => $username, 'email' => $email))
->subject('eParinay.com: New registration.')
->send();
} catch (Exception $e) {

echo 'Exception : ', $e->getMessage(), "\n";
}

Getting baseurl in any framework is easy. But development URL in cakephp 3 in view file…took time…For adding css or js or other purpose we need base path cakephp.

While doing development my path was http://localhost/cakephp3/. I wanted to fetch that in my site.
Their are many ways we can get the path.

You can use any one method of following :

<?php 
    echo $this->Html->url('/', true)
    echo $this->Html->url('/');
    ?>

Define constant in Config/core.php as given bellow:

define(“BASE_URL”, “localhost/cakephp3/”);

Then you can use BASE_URL in view file.

For view file you can use following code.

<?php echo $this->Url->build('/', true); ?>

I used above code reference to following URL:
