Pass array to Modal

Question

I have the following array $detalhes:

 Array ( [0] => Array ( [dt_detalhes] => 2016-03-09 [desc_detalhes] => Viabilidade [tp_processo] => Viabilidade [vl_protocolo] => 1234 ) 
         [1] => Array ( [dt_detalhes] => 2016-03-12 [desc_detalhes] => Sincronizado [tp_processo] => Sincronizado [vl_protocolo] => 12345 ) 
         [2] => Array ( [dt_detalhes] => 2016-03-11 [desc_detalhes] => Integrador [tp_processo] => Integrador [vl_protocolo] => 123456 ) )

I’d like to move him into a modal, that way:

<button type="button" data-toggle="modal" data-target="#detalhes" 
data-id="<?=$linha['id_processo']?>" data-detalhes="<?=$details?>">

How can I do that? In the way tried above the following error:

Array to String Conversion

OBS: I need to pass the entire array.

Answer 1

The echo serves to print scaler values(int, string float etc) except arrays and objects.

You can take the array and turn it into a json string with php and by javascript convert to an object.

<button id="button" type="button" data-toggle="modal" data-target="#detalhes" 
data-id="<?=$linha['id_processo']?>" data-detalhes="<?=json_encode($detalhes);?>">

In javascript:

var data = document.getElementById('button');
var json = JSON.parse(data.getAttribute('data-detalhes'));
console.log(json);

If you want to print array specific data, you need to print so:

echo $details[0]['dt_detalhes'];

He will print the field dt_detalhes of the first array item 0

If you want to print all fields and arrays, you should run them using some loop function, example:

for($i=0; $i < count($details); $i++) {
    echo $details[$i]['dt_detalhes']; // campo desejado, exemplo 'vl_protocolo'
}

To better understand how an array works read the documentation, in case I have doubts, post here.
