Laravel some questions (pagination, if - foreach) - php

Question

I'm laravel newbie. I'm created simple code and I have some questions:
I think this code bad (it works, but I use #forelse($forums as $forum) and anywhere use $forum)
#extends('layouts.main')
#section('content')
#forelse($forums as $forum) <-- I don't like this line, it works but i think it's possible with if or something else
#forelse($topics as $topic)
{{ $topic->title }}<br>
#empty
Sorry but this forums empty.
#endforelse
#empty
Sorry but this forum not found
#endforelse
#stop
And second question how to make pagination? I'm tried this:
<?php
namespace App\Http\Controllers;
use DB;
use View;
class viewForum extends Controller
{
public function showForum($fname, $fid)
{
return View::make('forum', [
'forums' => DB::table('forums')
->where('id', $fid)
->where('seo_name', $fname)
->select()
->get()
->simplePagination(5)
]);
}
}
But not work's, I'm tried tutorials..etc, how to? Thanks so much in advance ! :)

Answer 1

for your first question. You can use #foreach or #each. these are the two that i usually used.
for your second question:
return View::make('forum', [
'forums' => DB::table('forums')
->where('id', $fid)
->where('seo_name', $fname)
->select()
->paginate(5);
]);
remove ->get()
and replace simplePagination(5) with paginate(5)
documation http://laravel.com/docs/5.0/pagination
Update
change you code block from
return View::make('forum', [
'forums' => DB::table('forums')
->where('id', $fid)
->where('seo_name', $fname)
->select()
->paginate(5);
]);
to
$forums = DB::table('forums')
->where('id', $fid)
->where('seo_name', $fname)
->select()
->paginate(5);
return View::make('forum', compact('forums'));
then check if $forums->render() got error.
Update
$forums = DB::table('forums')
->where('id', $fid)
->where('seo_name', $fname)
->select()
->get(5);
$topics = DB::table('topics')
->where('forum_id', $id)
->select()
->paginate(2)
return View::make('forums', compact('forums', 'topics'));
on your view you do <?php echo $topics->render() ?> since topic is the one you paginate. also you can remove ->select() from your code. if you don't specify fields to output.

Answer 2

For #foreach ($topics as $topic)
{{$topic->title}}
#endforeach
For Pagination
$users = User::where('status','1')
->paginate(10);
Note: In View add this {{$user->links()}} for getting the pagination links.

Answer 3

you can use #foreach() #endforeach and probably #if #else #endif
see sample:
#foreach($forums as $forum)
#if($forum==0)
{{'empty'}}
#else
{{ 'Not empty' }}
#endif
#endforeach

Answer 4

for pagination i will suggest you use jquery datatable for proper pagination. Its quite okay and saves lots of time. see below the sample implementation:
//this preload the jquery library for datatable together with the print button
<script src="https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js"></script>
<script src="https://cdn.datatables.net/buttons/1.5.2/js/dataTables.buttons.min.js"></script>
<script src="https://cdn.datatables.net/buttons/1.5.2/js/buttons.print.min.js"></script>
//this section call the document ready event making sure that datatable is loaded
<script>
$(document).ready(function() {
$('#').DataTable();
} );
//this section display the datatable
$(document).ready(function() {
$('#mytable').DataTable( {
dom: 'Bfrtip',
"pageLength": 5, //here you can set the page row limit
buttons: [
{
extend: 'print',
customize: function ( win ) {
$(win.document.body)
.css( 'font-size', '10pt' )
.prepend(
''
);
$(win.document.body).find( 'table' )
.addClass( 'compact' )
.css( 'font-size', 'inherit' );
}
}
]
} );
} );
</script>
//you can display record on the datatable as shown below
<div class="table-responsive col-md-12">
<table id="mytable" class="table table-bordered table-striped table-highlight">
<thead>
<tr bgcolor="#c7c7c7">
<th>S/N</th>
<th>Name</th>
</tr>
</thead>
<tbody>
#php
$i=1;
#endphp
#foreach($queryrecord as $list)
<tr>
<td>{{ $i++ }}</td>
<td>{{ $list->name }}</td>
</tr>
#endforeach
</tbody>
</table>
<hr />
</div>
Note: remember before displaying information on the datatable, you must have query your record from database.i'm using query builder here as sample
$data['queryrecord']=DB::table('tablename')->get();
