jqGrid dataInit doesn't trigger - php

Question

I'm working with a project that uses jqGrid in the most recent version.
The thing is that this project is PHP(5.6) and uses JSON to "translate/talk" to jqGrid framework, and colModel parameters are all inside PHP arrays. It works flawlessly but i'm unable to trigger dataInit of colModel "criacao" using the actual project's code.
public function laudos($section)
{
$table = 'laudos';
$fields = array('id','laudo','nome_fantasia','cliente','cadastro_id','email','senha','exame','descricao','criacao','exclusao','arquivo');
$tabela = array(
'colNames' => array('ID','Laudo','Clínica','Nome','Cadastro','Email','Senha','Exame','Descrição','Criação','Exclusão','Arquivo'),
'colModel' => array(
array('name'=>'id','hidden'=>true,'search'=>true,'key'=>true),
array('name'=>'laudo','index'=>'laudo','width'=>70,'align'=>'center','search'=>true,'editable'=>true,'editrules'=>array('required'=>true),'sorttype'=>'integer','searchoptions'=>array('sopt'=>'[eq,cn]', 'clearSearch'=>false)),
array('name'=>'nome_fantasia','search'=>true,'width'=>170,'align'=>'center','editable'=>false,'sorttype'=>'text','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false),'editrules'=>array('required'=>true)),
array('name'=>'cliente','search'=>true,'width'=>170,'align'=>'center','editable'=>false,'sorttype'=>'text','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false),'editrules'=>array('required'=>true),),
array('name'=>'cadastro_id','search'=>true,'hidden'=>true,
'editable'=>true,'edittype'=>'text','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false),'editrules'=>array('edithidden'=>true,'required'=>true),
'editoptions'=>array('dataInit'=>'[]')),
array('name'=>'email','search'=>true,'hidden'=>true,'editable'=>true,'sorttype'=>'email','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false),'editrules'=>array('edithidden'=>true)),
array('name'=>'senha','search'=>true,'hidden'=>true,'editable'=>true,'editrules'=>array('edithidden'=>true)),
array('name'=>'exame','search'=>true,'width'=>50,'align'=>'center','editable'=>true,'sorttype'=>'text','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false),'formatter'=>'select','edittype'=>'select',
'editoptions'=>array('value'=>array('Biópsia'=>'Biópsia','Necrópsia'=>'Necrópsia','Citologia'=>'Citologia'))
),
array('name'=>'descricao','search'=>true,'width'=>200,'align'=>'center','editable'=>true,'sorttype'=>'text','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false)),
array('name'=>'criacao','search'=>true,'width'=>70,'formatter'=>'date','fixed'=>true,'resizable'=>false,'align'=>'center','sorttype'=>'date','searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false), 'editoptions'=>array('dataInit'=>'function (elem) { $(elem).datepicker();')),
array('name'=>'exclusao','search'=>true,'width'=>70,'formatter'=>'date','sorttype'=>'date','fixed'=>true,'resizable'=>false,'editable'=>true,'searchoptions'=>array('sopt'=>'[eq,cn]','clearSearch'=>false),'align'=>'center'),
array('name'=>'arquivo','search'=>false,'width'=>60,'formatter'=>'arquivo','classes'=>'tabela_laudo_arquivo','editable'=>true,'searchoptions'=>array('sopt'=>false,'clearSearch'=>false))
),
'sortname' => 'id',
'caption' => 'Registros de Laudos Cadastrados',
);
This is the PHP function that returns a responce to jqgrid framework:
private function tabelas($table, $fields, $where = '1 = 1')
{
$page = isset($_REQUEST['page']) ? $_REQUEST['page'] : 1; // get the requested page
$limit = isset($_REQUEST['rows']) ? $_REQUEST['rows'] : 99999; // get how many rows we want to have into the grid
$sidx = isset($_REQUEST['sidx']) ? $_REQUEST['sidx'] : 'id'; // get index row - i.e. user click to sort
$sord = isset($_REQUEST['sord']) ? $_REQUEST['sord'] : 'desc'; // get the direction
if(!$sidx) $sidx =1;
$count = $this->db->get_var("SELECT COUNT(*) AS count FROM $table WHERE $where");
if($count > 0)
{
$total_pages = ceil($count/$limit);
}
else
{
$total_pages = 0;
}
if ($page > $total_pages) $page = $total_pages;
$start = $limit * $page - $limit; // do not put $limit*($page - 1)
$sql = "SELECT " . implode(',',$fields) . " FROM $table WHERE $where ORDER BY $sidx $sord LIMIT $start, $limit";
$result = $this->db->get_results($sql);
$responce->page = $page;
$responce->total = $total_pages;
$responce->records = $count;
$i = 0;
foreach($result as $row)
{
$responce->rows[$i]['id'] = $row->id;
foreach($fields as $field)
{
$responce->rows[$i]['cell'][] = $row->$field;
}
$i++;
}
return $responce;
}

Answer 1

Using $.extend in my jQGrid script did the job.
