Hi everyone,
I'm facing an issue with assigning a variable in Smarty template engine using PHP. I have been trying to assign a value to a Smarty variable, but for some reason, it doesn't seem to be working.
Here's the code snippet where I'm trying to assign the variable:
```php
$smarty = new Smarty;
$template_dir = 'path_to_my_templates';
$smarty->template_dir = $template_dir;
$smarty->assign("myVariable", "Hello World");
```
After assigning the value, I am attempting to use the `myVariable` in my Smarty template, but it appears to be empty:
```smarty
<html>
<head>
<title>My Template</title>
</head>
<body>
<h1>{$myVariable}</h1>
</body>
</html>
```
When I view the output, the `h1` tag is empty. I have checked that the template file paths are correct, and I am able to load and display the template without any issues. However, the assigned variable doesn't seem to pass the value.
Am I missing something here? Is there a specific syntax or step that needs to be followed in order to assign a Smarty variable correctly? Any help or suggestions would be greatly appreciated!
Thank you!

Hey there!
I faced a similar issue before, and it turned out that I didn't have the necessary Smarty library included in my project. So make sure you have the correct dependencies installed, including Smarty. You can check if the `smarty.class.php` file is present in your project.
Also, double-check your template file paths and ensure the variable assignment is happening before the template is rendered. Sometimes the order of operations can make a difference. Additionally, ensure that you are using the correct Smarty template tags (`{$myVariable}`) in your template file.
Another thing to consider is Smarty caching. It's possible that your template is being cached with an empty value for `myVariable`. Try clearing your Smarty cache and see if that resolves the issue.
If the problem persists, it could be helpful to share more details about your project's file structure or any relevant error messages you may have encountered. With that information, the community might be able to provide more specific guidance.
Hope this helps and good luck!
