Get the id of an element of a GROUP_CONCAT? - php

Question

I made a query to group all the Audits belonging to a specific Area, like in the next query.
SELECT id_Area as idArea, area.Name as area_name, GROUP_CONCAT(id_Audit) as Audits
FROM helios.fsa_audits
LEFT JOIN helios.fsa_areas area USING (id_Area)
WHERE id_Auditor='4'
GROUP BY id_Area;
As result I get this:
I made this to get a datatable in the view like this:
But What I need is to get the id of the Audit at the moment of click each button in the Auditorias.
I'm working with symfony, and I render the datatable like this:
<table aria-describedby="dataTable_info" cellspacing="0" class="table table-hover dataTable" id="dataTable" role="grid" style="width:100%;" width="100%">
<thead>
<tr>
<th>Areas</th>
<th>Auditorias</th>
</tr>
</thead>
<tbody>
{% for audit in auditsByArea %}
<tr>
<td>{{ audit.area_name }}</td>
<td>
{% for i in 1..4 %}
<input class ="auditBtn mx-2" value="{{'W' ~ i }}" href="" data-id="{{ audit.Audits }}" data-area="{{ audit.area_name }}"id="auditBtn" name="auditBtn" type='text' readonly data-toggle="modal" data-target="#auditModal"></input>
{% endfor %}
</td>
</tr>
{% endfor %}
</tbody>
</table>
But it does not put the one id per button(Audit), it assigns all the id's in all the buttons:
data-id="10,11,12,13"
Any idea or suggestion about how to get it?

Answer 1

I'm not in symfony but you should explode your group_concat result
my_array = explode({{ audit.Audits }});
then in you loop refer to the content on the array
<td>
{% for i in 1..4 %}
<input class ="auditBtn mx-2" value="{{'W' ~ i }}" href="" data-id="{{ my_array[i] }}" data-area="{{ audit.area_name }}"id="auditBtn" name="auditBtn" type='text' readonly data-toggle="modal" data-target="#auditModal"></input>
{% endfor %}
