Hey,

We have written a Drupal module controller. It allows a user to select a course then enroll in the course. Upon successful enrollment the user is allowed to select another course and enroll in that course. After doing the enrollment process successfully 5 to 6 even 12 times in a row the course enrollment fails with this error in the browser console.

Hi,

I have some modules from a D7 site wich i shold convert to D9/D10

I use the

drush dmu-analyze modulename

Which works perfectly and i can remove old issues and obstacles.

But when it comes to classes, it really dont work.

I have followed some guides and everything fails, either because its not a Drupal namespace or it cant be found.

I would really apprechiate any help in this.

Hello,

I have a custom form in which I want to add several inputs. In the following test, I add a "car2" field. Visually I can see the new input created, but when I submit the form, "car2" is not present in $form and $form_state, there is only "car1".

I think I'm missing a behavior that wicks :p

Hi,

my requirement is to get thumbprint of the certificate and I am trying to use this 

$thumb = openssl_x509_fingerprint($certContent,"RSA-SHA256",false);

$thumb1 = openssl_x509_fingerprint($certContent,"sha256",false);

But the return of the above is not matching with the thumbprint.

when I open the cert and check "Details" --> Thumbprint , it is different than what is returned from above function. when I check here "signature algorithm = sha256RSA"   and "signature hash algorithm = sha256"

Please let me know if I am missing something.

I have viewed several user account Time Limit modules but they appear to be associated with older versions of Drupal - not Drupal 10.

I am seeking an existing module that essentially does the following and will work in Drupal 10:

1. A User Expiry Date field is added to the database.

2. Create time limits on user accounts so their access expires at a certain date.

3. It automatically sends a reminder notification to administrators that the user account is expiring 14/7/1 days before it expires.
