php - Adding a conditional statement to an array of fields? -

i need include conditional statement following array called $fields.

$fields = [     'program_id'     => [         'type'        => 'select',         'label'       => 'program',         'opts'        => ["one", "two", "three"],     ],     'name'           => [         'label' => 'job name'     ],     'start_date'         => [         'class' => 'date-picker',         'label' => 'job starts' . $req,         'val'   => $job->start_date ? datetopicker($job->start_date) : null     ],     'end_date'           => [         'class' => 'date-picker',         'label' => 'job ends' . $req,         'val'   => $job->end_date ? datetopicker($job->end_date) : null     ],     'section'            => [         'type' => 'hidden',         'val'  => 'details'     ], ]; if (!$job->id && $program) {     $fields['job_copy'] = [         'label'       => 'copy job from',         'type'        => 'select',         'textasvalue' => false,         '_comment'    => 'selecting job here copy job information except name.',         'opts'        => array_replace([0 => '-- select job --'], $program->jobs()->lists('name', 'id')->all())     ]; } $fields[] = [     'type'  => 'submit',     'label' => "save",     'class' => 'btn btn-primary !important' ]; 

}

i need move conditional statement top first thing displayed on form. however, when move top disappears. how can integrate conditional check top of form opposed @ bottom displays?

$fields  = []; if (!$job->id && $program) {     $fields['job_copy'] = [         'label'       => 'copy job from',         'type'        => 'select',         'textasvalue' => false,         '_comment'    => 'selecting job here copy job information except name.',         'opts'        => array_replace([0 => '-- select job --'], $program->jobs()->lists('name', 'id')->all())     ]; }  $fields2 = [     'program_id'     => [         'type'        => 'select',         'label'       => 'program',         'opts'        => ["one", "two", "three"],     ],     'name'           => [         'label' => 'job name'     ],     'start_date'         => [         'class' => 'date-picker',         'label' => 'job starts' . $req,         'val'   => $job->start_date ? datetopicker($job->start_date) : null     ],     'end_date'           => [         'class' => 'date-picker',         'label' => 'job ends' . $req,         'val'   => $job->end_date ? datetopicker($job->end_date) : null     ],     'section'            => [         'type' => 'hidden',         'val'  => 'details'     ], ]; $fields = array_merge($fields,$fields2); $fields[] = [     'type'  => 'submit',     'label' => "save",     'class' => 'btn btn-primary !important' ];
