How to Check If A Record Exists In October CMS?

7 minutes read

To check if a record exists in October CMS, you can follow these steps:

  1. Open your October CMS project in your preferred code editor.
  2. Identify the model or database table that contains the record you want to check. Models in October CMS are located in the models directory.
  3. Inside the relevant model file, locate the method where you want to check if the record exists. This method is often the one responsible for handling the logic related to the record.
  4. Use the query builder methods provided by October CMS to query the model and check if the record exists. The where method is commonly used for this purpose.
  5. With the where method, you can specify the condition to search for the record. For example, if you want to check if a record with the ID of 1 exists, you can write $record = Model::where('id', 1)->first();.
  6. The first method retrieves the first record that matches the condition. If no record is found, it will return null.
  7. Finally, check the value of the variable that holds the record. If it is null, then the record does not exist. Otherwise, the record exists.


Here is a sample code snippet to demonstrate the process:

public function checkRecordExists()
{
    $record = Model::where('id', 1)->first();

    if ($record === null) {
        // Record does not exist
        // Perform desired actions
    } else {
        // Record exists
        // Perform desired actions
    }
}


Remember to replace Author\Plugin\Models\Model with the correct namespace and model name based on your project's structure.

How to check if a CMS page exists in October CMS?

In October CMS, you can check if a CMS page exists using the Cms\Classes\CmsPage class. Here's how you can do it:

  1. Use the Cms\Classes\CmsPage namespace at the top of your file:
1
use Cms\Classes\CmsPage;


  1. Inside your method, create an instance of the CmsPage class using the page URL or file name:
1
$page = CmsPage::load('your-page-url-or-filename');


  1. You can then check if the page exists using the exists method:
1
2
3
4
5
if ($page->exists) {
    // Page exists
} else {
    // Page does not exist
}


Alternatively, you can also use the isClassExtendedWith method to check if the page you're looking for exists:

1
2
3
4
5
if (CmsPage::isClassExtendedWith('your-page-url-or-filename')) {
    // Page exists
} else {
    // Page does not exist
}


Make sure to replace 'your-page-url-or-filename' with the actual URL or file name of the CMS page you want to check.


How to check if a backend controller exists in October CMS?

To check if a backend controller exists in October CMS, you can use the class_exists function. Here's an example:

1
2
3
4

6

if (class_exists('\Author\Plugin\Controllers\MyController')) {
    // The backend controller exists
    // Your code here
} else {
    // The backend controller does not exist
    // Your code here
}


In the class_exists function, you need to pass the fully qualified name of the backend controller as a string. Replace \Author\Plugin\Controllers\MyController with the actual namespace and class name of your backend controller.


If the backend controller exists, the class_exists function will return true, and you can proceed with the code to handle that controller. If the backend controller does not exist, the function will return false, and you can handle the situation accordingly.
