Automatically be notified of any errors on your server

Sometimes a script on your website/server might be causing some errors that you are unaware of. Some users might be seeing these errors under certain circumstances and others not. If users don’t report these errors, you won’t know unless you’re regularly checking your server logs. But no one likes to check server logs as part of their daily routine 🙂 So, here is a one-liner you can add to your crontab file:

The above line would automatically check your server daily at 2:00 am for any error_log files modified within the last 1 day (this is what the option -mtime -1 above does). If any ones are found, you’ll get an email listing them — don’t forget to change the email address above to your email.

Displaying count of child records on the tab title

AppGini supports displaying a list of child records in the detail view of the parent record. For example, here is the detail view of an employee record from the online Northwind demo:

(Ignore the weird cartoons for now!) So … It would be nice if the count of subordinates is displayed on the ‘Subordinates’ tab, as well as the count of ‘Initiated orders’ on its tab title. One way of doing this is through JavaScript. Add the following code to the generated hooks/footer-extras.php file:

Afterwards, all child tabs for all tables would display a count of child records. Here is how this looks for our employee above:

The count would auto-update if you add or remove any child records. We might implement this functionality in future releases of AppGini. For now, I hope this helps 🙂

Retrieve a list of users who haven’t made any activity in the last x months

I just got an interesting question from an AppGini user:

Is there an SQL query that I can run manually in PhpMyAdmin that will show me a list of all users that haven’t logged into AppGini for the last 6 months please? Even if it is using one of the date fields in the membership_users table to show me a list of all users that haven’t added or changed a record for the last 6 months, that would suffice.

Well, AppGini doesn’t currently (until AppGini 5.72) store the login date/time of users (but we plan to add this in future releases). So, what we can do is run a query to retrieve non-active users (with no insert/edit activity in the last 6 months).

First, we need to create a new view in MySQL to list users’ last activity:

Now, you can use the view ‘members_activity’ that we defined above like you use any table (except it’s not actually a table, but it makes our life easier when performing complex queries). So, to retrieve all users who have no insert/update activity or whose last insert/update activity is more than 6 months old:

But the above query might retrieve new users who joined less than 6 months ago … to exclude those, we should add another condition:

Hiding the nicedit component from a page

AppGini uses nicedit Javascript component for displaying rich text areas, where users can enter formatted input. You might wish to hide/show the rich editor in an AppGini page, or in one of your custom pages. This can be done using JavaScript code.

To hide nicedit components in a page:

How to hide a field in child table view?

In many cases, your application might have a child table, like this:

An example child table in an AppGini application. We want to hide some columns from that table.

Let’s say we want to hide the Company and Open columns from that child table. You can add a CSS rule to hide specific columns from the child table. In the generated hooks/footer-extras.php, add code similar to this:
