Add separator between foreach returned values - php

Question

I have the following foreach returning values :
#foreach($content['order'] as $products)
<tr>
<td><span>{{ $products->Type }} {{ $products->Nom }} {{ $products->{'# Personnes'} }} {{ $products->Inscription }} {{ $products->{'Décoration Chocolat et fruits'} }} {{ $products->{'Décoration petites fleurs'} }} {{ $products->Décoration }} {{ $products->{'Nombre de sandwiches'} }} {{ $products->Poids }} {{ $products->{'Assortiment 1'} }} {{ $products->{'Assortiment 2'} }} {{ $products->{'Assortiment 3'} }} {{ $products->{'Assortiment 4'} }} {{ $products->{'Couleur Ruban'} }} {{ number_format($products->Prix, 2) }} {{ number_format($products->Supplément, 2) }} {{ number_format($products->{'Supplément décoration'}, 2) }} {{ number_format($products->Total, 2) }}</td>
</tr>
#endforeach
I would like to add a separator between each returned values (except for the last).
I added
.' | '
{{ $products->Type.' | ' }} {{ $products->Nom.' | ' }} {{ $products->{'# Personnes'}.' | ' }} {{ $products->Inscription.' | ' }} {{ $products->{'Décoration Chocolat et fruits'}.' | ' }} {{ $products->{'Décoration petites fleurs'}.' | ' }} {{ $products->Décoration.' | ' }} {{ $products->{'Nombre de sandwiches'}.' | ' }} {{ $products->Poids.' | ' }} {{ $products->{'Assortiment 1'}.' | ' }} {{ $products->{'Assortiment 2'}.' | ' }} {{ $products->{'Assortiment 3'}.' | ' }} {{ $products->{'Assortiment 4'}.' | ' }} {{ $products->{'Couleur Ruban'}.' | ' }} {{ number_format($products->Prix, 2).' | ' }} {{ number_format($products->Supplément, 2).' | ' }} {{ number_format($products->{'Supplément décoration'}, 2).' | ' }} {{ number_format($products->Total, 2) }}
Problem I have is that the separator is added even when no value is returned
Pie | Chocolate | 2-3 servings | Text | Decoration chocolate | Decoration flowers | | | | | | | | | 19.00 | 5.00 | 0.00 | 24.00
How can I print a separator only if a value is returned.
Thanks

Answer 1

#if(isset($products->Type)) {{ $products->Type. '|' }} #endif
This is an example of your first row how you can handle it. You check if exists and if it does you echo the result concatenating a separator on it.
small thing, mind your span tag, you are not closing it in the code you provided.

Answer 2

You can use ternary operator as a short hand for the same,
{{ !empty($products->Type) ? $products->Type.' | ': '' }}
Do this for all the fields

Answer 3

There's several way of going about this, but one quite dynamic way would be to fetch all the values into an array instead, filter it for non-empty values and implode it.
We'd be using standard PHP, which you can do within blades.
<?php
foreach($content['order'] as $products) {
$values = [];
$values[] = $products->Type;
$values[] = $products->Nom;
$values[] = $products->{'# Personnes'};
$values[] = $products->Inscription;
$values[] = $products->{'Décoration Chocolat et fruits'};
$values[] = $products->{'Décoration petites fleurs'};
$values[] = $products->Décoration;
$values[] = $products->{'Nombre de sandwiches'};
$values[] = $products->Poids;
$values[] = $products->{'Assortiment 1'};
$values[] = $products->{'Assortiment 2'};
$values[] = $products->{'Assortiment 3'};
$values[] = $products->{'Assortiment 4'};
$values[] = $products->{'Couleur Ruban'};
$values[] = number_format($products->Prix, 2);
$values[] = number_format($products->Supplément, 2);
$values[] = number_format($products->{'Supplément décoration'}, 2);
$values[] = number_format($products->Total, 2);
echo "<td>".implode(" | ", array_filter($values))."</td>";
}
?>

Answer 4

Turn into array, filter empty values and implode with an " | " string
{{join("|", array_filter([
$products->Type ,
$products->Nom ,
$products->{'# Personnes'} ,
$products->Inscription ,
$products->{'Décoration Chocolat et fruits'} ,
$products->{'Décoration petites fleurs'} ,
$products->Décoration ,
$products->{'Nombre de sandwiches'} ,
$products->Poids ,
$products->{'Assortiment 1'} ,
$products->{'Assortiment 2'} ,
$products->{'Assortiment 3'} ,
$products->{'Assortiment 4'} ,
$products->{'Couleur Ruban'} ,
number_format($products->Prix, 2) ,
number_format($products->Supplément, 2) ,
number_format($products->{'Supplément décoration'}, 2) ,
number_format($products->Total, 2)
]))}}
