_name == '') ? $redText : ''; ?>
Here is what the above code is Doing:
1. It’s checking to see if the $_POST[‘name’] variable is empty.
2. If it is, it’s setting the $redText variable to the HTML code for a red asterisk.
3. It’s then using the $redText variable in the HTML code for the form.
The result is that if the user doesn’t enter a name, the form will be redisplayed with a red asterisk next to the name field.
The code for the email field is similar:
$news1 = DB::table(‘posts’)->where(‘xstatus’,1)->where(‘status’,’published’)->orderBy(‘seq’,’DESC’)->skip(0)->first(); $news2 = DB::table(‘posts’)->where(‘xstatus’,1)->where(‘status’,’published’)->orderBy(‘seq’,’DESC’)->skip(1)->first(); $news3 = DB::table(‘posts’)->where(‘xstatus’,1)->where(‘status’,’published’)->orderBy(‘seq’,’DESC’)->skip(2)->first(); Here is what the above code is Doing: 1. We are selecting all the posts from the database where the xstatus is 1 and the status is published. 2. We are ordering the posts by the seq column in descending order. 3. We are skipping the…
$number = ‘1,000.5669’; $number = (float) str_replace(‘,’, ”, $number); var_dump($number); Here is what the above code is Doing: 1. We’re using the str_replace() function to replace the comma with an empty string. 2. We’re casting the result to a float. 3. We’re dumping the result to the screen.
$user = User::find(1); $user->roles()->updateExistingPivot($roleId, [ ‘active’ => false, ], false); //The last param is to not update time updated_at column timestamp. Here is what the above code is Doing: 1. Find the user with id 1 2. Find the role with id 1 3. Update the pivot table entry for the user with id 1…
Here is what the above code is Doing: 1. The wire:keydown directive listens for the keydown event on the element. 2. The .enter modifier listens for the enter key. 3. The doSomething method is called when the enter key is pressed. The wire:keydown directive also accepts a second argument, which is the key code of…
$affected = DB::table(‘users’) ->where(‘id’, 1) ->update([‘votes’ => 1]); Here is what the above code is Doing: 1. We’re using the DB facade to access the database. 2. We’re using the table method to specify which table we want to query. 3. We’re using the where method to specify which column we want to check. 4….
