Symfony : multiple "for" loops in Twig - symfony

Question

I have all these {% for %} loops that are nested one inside the other but I would like them to be all at the same level. Independent from one another because like this, my goalkeepers only appear if there are defenders, midfielders... I would like them all to appear wether one category is missing or not.
<tbody>
{% for defenser in defensers %}
{% for midfielder in midfielders %}
{% for forward in forwards %}
{% for gk in goalkeepers %}
<tr>
<td>
<div class="player-in-club">
{{ gk.name }}
</div>
</td>
<td>
<div class="player-in-club">
{{ defenser.name }}
</div>
</td>
<td>
<div class="player-in-club">
{{ midfielder.name }}
</div>
</td>
<td>
<div class="player-in-club">
{{ forward.name }}
</div>
</td>
</tr>
{% endfor %}
{% endfor %}
{% endfor %}
{% endfor %}
</tbody>

Answer 1

You can ensure that your arrays always contain at least one (empty string) Element if you put this in front of your for loops:
{% if defensers is empty %}
{% set defensers = [""] %}
{% endif %}
{% if midfielders is empty %}
{% set midfielders = [""] %}
{% endif %}
{% if forwards is empty %}
{% set forwards = [""] %}
{% endif %}
{% if goalkeepers is empty %}
{% set goalkeepers = [""] %}
{% endif %}
But I feel like you want something kompletely differently. The way you have set up your loops they will print every possible row kombination.
If you just want a table that is filled as the items are available you might want to use this instead of your loops:
{% set row_count = max(defensers|length, midfielders|length, forwards|length, goalkeepers|length) %}
<tbody>
{% for index in range(0, row_count - 1) %}
<tr>
<td>
<div class="player-in-club">
{% if goalkeepers[index] %}
{{ goalkeepers[index].name }}
{% endif %}
</div>
</td>
<td>
<div class="player-in-club">
{% if defensers[index] %}
{{ defensers[index].name }}
{% endif %}
</div>
</td>
<td>
<div class="player-in-club">
{% if midfielders[index] %}
{{ midfielders[index].name }}
{% endif %}
</div>
</td>
<td>
<div class="player-in-club">
{% if forwards[index] %}
{{ forwards[index].name }}
{% endif %}
</div>
</td>
</tr>
{% endfor %}
</tbody>
