Q:

Cakephp 4.x Passing Variables to Email Template

Hi everyone,

I hope you're all doing well.

I'm having some difficulties passing variables to an email template in CakePHP 4.x. I have looked through the documentation and tried a few different things, but I can't seem to get it to work.

Here's what I'm trying to achieve: I want to send an email to a user and include some dynamic data in the email body. For example, I want to include the user's name, username, and email address in the email.

I have already set up the email configuration in my `app.php` file, and I can successfully send emails using the default template. But I can't figure out how to pass variables to the email template and use them in the email body.

I have tried following the instructions in the CakePHP documentation, specifically the section on "Sending email with view templates". I have created a custom email template in the `src/Template/Email/html` folder, and I have tried passing variables to the template using the `set()` method, but it doesn't seem to work.

Here's an example of what I have tried in my controller:

```php
$email = new Email('default');
$email->setTemplate('welcome')
->setEmailFormat('html')
->setTo('user@example.com')
->setViewVars(['name' => 'John Doe', 'username' => 'johndoe', 'email' => 'johndoe@example.com'])
->send();
```

And in my custom email template (`src/Template/Email/html/welcome.ctp`), I have tried accessing the variables using `$name`, `$username`, and `$email`, but it doesn't seem to work. The variables are always empty.

I have also tried passing variables using the `viewBuilder()` method in the `build()` function of my email template, like this:

```php
$this->viewBuilder()->setVars(['name' => 'John Doe', 'username' => 'johndoe', 'email' => 'johndoe@example.com']);
```

But that didn't work either.

Am I missing something here? Is there a different way to pass variables to email templates in CakePHP 4.x? Any help would be greatly appreciated.

Thank you in advance.

Hello there,

I had a similar issue with passing variables to email templates in CakePHP 4.x, and I found a different approach that worked for me. Instead of using the `setViewVars()` or passing variables directly to the `send()` method, I used the `set()` method within the email template itself.

First, make sure you have the necessary variables available in your controller method. For example, let's say you have `$name`, `$username`, and `$email` variables defined in your controller. Then, when configuring your email, you don't need to pass any variables:

php
$email = new Email('default');
$email->setTemplate('welcome')
->setEmailFormat('html')
->setTo('user@example.com')
->send();


In your email template file (`src/Template/Email/html/welcome.ctp`), you can access the variables using the `$this->set('variableName', $variableValue)` syntax. Here's an example:

php
$this->set('name', $name);
$this->set('username', $username);
$this->set('email', $email);


After doing this, the variables should be accessible within the email template using `$name`, `$username`, and `$email`.

Give this approach a try and see if it works for you. Let me know if you have any further questions!

Best regards.

Hey there,

I've encountered a similar issue before, and I managed to solve it by following a slightly different approach. Instead of using the `setViewVars()` method, try passing the variables directly to the `send()` method as an array.

Here's an example:

php
$email = new Email('default');
$email->setTemplate('welcome')
->setEmailFormat('html')
->setTo('user@example.com')
->send(['name' => 'John Doe', 'username' => 'johndoe', 'email' => 'johndoe@example.com']);


To access the variables in your email template, you should use the `$this->get('variableName')` syntax. In your case, you would use `$this->get('name')`, `$this->get('username')`, and `$this->get('email')`.

Give this approach a try and see if it works for you. Let me know if you have any further questions!

Best regards.
