I am passing the array $cats to my laravel template view. It is a multidimensional array from a database transaction, containing category data. So it would contain data like:
$cat[0]['id'] = 1;
$cat[0]['name'] = 'First Category';
And so on. In my blade template I have the following code:
{{ $i=0 }}
@foreach($cats as $cat)
{{ $cat['name'] }}<br />
{{ $i++ }}
@endforeach
Which outputs:
0 First Category
1 Second Category
2 Third Category
Notice the numbers preceding the category name. Where are they coming from? Is this some clever Laravel trick? It seems that when you include a counter variable, they are automatically added. I can't find any mention of it anywhere, and I don't want them! How do I get rid of them?
Thanks.
You just need to use the plain php translation:
@foreach ($collection as $index => $element)
{{$index}} - {{$element['name']}}
@endforeach
EDIT:
Note the $index
will start from 0
, So it should be {{ $index+1 }}
The {{ }}
syntax in blade essentially means echo. You are echoing out $i++
in each iteration of your loop. if you dont want this value to echo you should instead wrap in php tags. e.g.:
<?php $i=0 ?>
@foreach($cats as $cat)
{{ $cat['name'] }}<br />
<?php $i++ ?>
@endforeach
As an additional note, if you choose to work in arrays then thats your call but unless you have a specific reason to do so I would encourage you to work with object syntax, eloquent collection objects in laravel can be iterated over just like arrays but give you a whole lot of extra sugar once you get used to it.
@foreach($cats as $cat)
{{ (isset($i))?$i++:($i = 0) }} - {{$cat['name']}}
@endforeach
