list multiple in one row in one column - php

Question

I am sorry but I don't even know how to title this question since I have no clue what to look for.
Here is my problem: I have the following list:
name
word
hit
Bill
performance
2
Anna
performance
5
John
performance
3
Bill
java
0
Anna
java
1
John
java
3
Bill
test
4
Anna
test
5
John
test
1
What I am trying to get is the following:
name
sum(hit)
words_count
Bill
6
performance = 2 java = 0, test = 4
Anna
11
performance = 5 java = 1, test = 5
John
7
performance = 3 java = 3, test = 1
I could sum all hits and group by words and so but I only need one dataset each name.
I think I need a subquery or so. How can I get the words_count column in that way?
Actually I need it a Laravel controller to display it in a datatable but an SQl statement would help me a lot also.
Appreciate your help.

Answer 1

Hi guys i thank you a lot for your answers.
I could manage it in SQL. So the statement is the following:
SELECT name, sum(hit) as points,
GROUP_CONCAT(concat(word, '->'), concat(hit, ' ') separator ' ' ) as words
FROM results
GROUP BY name;
This gives me exactly what i need.
I am display my data in a datatable (yajra). I will now "translate" this code to "laravel / php" code to feed my datatable.

Let's consider, you have a model named UserPerformance
$userPerformance = UserPerformance::all();
$result = $userPerformance->groupBy('name');
And in your blade template:
<table>
<thead>
<tr>
<th>name</th>
<th>sum(hit)</th>
<th>words_count</th>
</tr>
</thead>
<tbody>
#foreach($userPerformance as $name => $performance)
<tr>
<td>{{ $name }}</td>
<td>{{ $performance->sum('hit') }}</td>
<td>
{{ $performance->map(function($p) { return $p->word.' = '.$p->hit; })->implode(', ') }}
</td>
</tr>
#endforeach
</tbody>
</table>
You can also add your map() code to your model using an accessor to keep the blade template clean:
class UserPerformance extends Model
{
public function getWordCountAttribute()
{
return $performance->map(function($p) {
return $p->word.' = '.$p->hit;
})->implode(', ');
}
}
You can access it like this: $userPerformanceModel->word_count;
That also enables you, to re-use the code. You can also append this accessor during serialization to use it client-side.
