问题 How can I escape a LIKE clause in Laravel/Eloquent? e.g., $search = Input::query('sSearch', ''); if($search !== '') { $paginatedBookings->where('first_name', 'LIKE', '%' . $search . '%'); } If $search contains a % or _ they need to be escaped. 回答1: The other answer forgets about escaping the escape character itself, here is a more robust solution: /** * Escape special characters for a LIKE query. * * @param string $value * @param string $char * * @return string */ function escape_like(string

问题 I'm creating a basic list view of posts, and need a link to the 'edit' page. I'm using blade, and what I have is a table, with a foreach loop, showing each post along with edit/delete buttons. What I wanted to do is use blade's URL::to for the links to the edit and delete pages, to ensure consistant links. The code I've tried using (remember this is inside a foreach loop hence the $post->id var) is this: <a href="{{ URL::to('admin/posts/edit/$post->id') }}" class="btn btn-mini btn-primary"

问题 I'm using the laravel framework for a project, and I'm implementing a basic form page, where I require certain values to be required , something that can be done very easily in HTML5. <input type="text" name="abc" required> In laravel, without the required attribute, the same would be : {{ Form::text('abc') }} How do I incorporate a required attribute in the above statement? 回答1: Since simply writing ['required'] did not work, I searched online a bit more and found the answer, so I thought I

问题 So i have watched the 5 part youtube videos by David Mosher about Angular JS (vids great by the way). In the part 2 (http://www.youtube.com/watch?v=hqAyiqUs93c), it has a practical mysql database usage which I almost wanted. I'm going to use AngularJS along with Laravel 4, but I had no idea which files I'm going to upload for the web hosting later . I'm trying to run the web app under "/public" folder in my root on localhost (localhost/public/) but the css and js points to the wrong directory

问题 I'm using the following code to redirect the output of an artisan command within a route. use Symfony\Component\Console\Output\BufferedOutput; Route::get('/restart', function() { $output = new BufferedOutput; Artisan::call('remote:restart', array(), $output); return $output->fetch(); }); This works for most cases. However if within the command I use the SSH component to run some tasks on a remote server, the output resulting from SSH::into()->run() will be disregarded by the above code. If I

问题 I am very new to Laravel and PHP in general, most of what I have worked on has been relative to online tutorials. I know how to save single items like a username or password to my database but I am clueless when it comes to storing an entire file.This is how my database is currently formatted in my migration file: public function up() { Schema::create('users', function(Blueprint $table) { $table->increments('id'); $table->string('username'); $table->string('email')->unique(); $table->string(

问题 I was wondering if some Laravel guys can help out.

My radio

问题 I have the following query public static function createConversation( $toUserId ) { $now = date('Y-m-d H:i:s'); $currentId = Auth::user()->id; $results = DB::table('pm_conversations')->insert( array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now ) ); return $results; } How would i return the id of the row just inserted? Cheers, 回答1: Instead of doing a raw query, why not create a model... Call it Conversation, or whatever... And then you can

问题 I'm using the Lumen (by Laravel) micro-framework for a project, and I'm having some trouble with sessions. I'm just testing the implementation now, but the problem I'm experiencing is that when I set a session variable and then refresh the page, the variable is no longer set. In my .env file I have: SESSION_DRIVER=cookie And I know that this is being picked up, because when I change it to memcached it throws an error (because I don't have memcached set up). I've enabled the middleware too:
