Could someone please explain this condition to me? I'm having trouble understanding it. The code is functioning correctly, but I can't remember the logic I used to return the value.
$chkBlock = Blocked::where("block_username", "=", Auth::user()->username)
->where("user_username", "=", $username)
->count();
if ($chkBlock > 0) {
return \Redirect::back()->withSuccess( 'This User has blocked you' );
}
Retrieve the number of blocked records where the block username matches the authenticated user's username and the user username is equal to a specific variable.This SQL query will count the matching records based on the given conditions.
If the count of blocked records is greater than 0, redirect back to the previous page with a success message stating that the user has blocked you.This logic is used to handle situations where a user may have been blocked by another user.
When fetching data from the Blocked model, you are checking if a user is blocked or not.
To do this, you provide the current logged-in username (Auth::user()->username) and another username as well ($username).
$chkBlock = Blocked::where("block_username", "=", Auth::user()->username)
->where("user_username", "=", $username)
->count();
This query checks whether the blockeds table contains any rows with the current user and the given username ($username), and returns a count.
Now onto the second query:
if ($chkBlock > 0) {
return \Redirect::back()->withSuccess( 'This User Block you' );
}
You are looking to see if the rowCount has an entry. If the count is 1 or more than 0, it means that the user is blocked and you redirect back with the message This User Block you.
If you wish to view the MySQL query being executed, you can use the following:
DB::enableQueryLog();
//Your Model query goes here
dd(DB::getQueryLog());
It will display and dump the MySQL query for you to inspect.
