Tanya cara Membuat Meta Image Pada Marketplace Tajalapak dari Uraian Explode

Assalamualaikum,.. buka file : application\views\phpmu-marketpro\template.php lalu cari :
<?php if ($this->uri->segment(1)=='berita' AND $this->uri->segment(2)=='detail'){ $rows = $this->model_utama->view_where('berita',array('judul_seo' => $this->uri->segment(3)))->row_array();
echo '<meta property="og:title" content="'.$title.'" />
<meta property="og:type" content="article" />
<meta property="og:url" content="'.base_url().''.$this->uri->segment(3).'" />
<meta property="og:image" content="'.base_url().'asset/foto_berita/'.$rows['gambar'].'" />
<meta property="og:description" content="'.$description.'"/>';
} ?>
 
 
Kemudian lebih lengkapnya ubah menjadi seperti ini saja :
<?php if ($this->uri->segment(1) == 'berita' and $this->uri->segment(2) == 'detail') {
    $rows = $this->model_utama->view_where('berita', array('judul_seo' => $this->uri->segment(3)))->row_array();
    $directory_img = "foto_berita";
    $foto_meta = $rows['gambar'];
} elseif ($this->uri->segment(1) == 'produk' and $this->uri->segment(2) == 'detail') {
    $rows = $this->model_utama->view_where('rb_produk', array('produk_seo' => $this->uri->segment(3)))->row_array();
    $directory_img = "foto_produk";
    $ex = explode(';', $rows['gambar']);
    $foto_meta = $ex[0];
}
echo '<meta property="og:title" content="' . $title . '" />
<meta property="og:type" content="article" />
<meta property="og:url" content="' . base_url() . $this->uri->segment(1) . '/' . $this->uri->segment(2) . '/' . $this->uri->segment(3) . '" />
<meta property="og:image" content="' . base_url() . 'asset/' . $directory_img . '/' . $foto_meta . '" />
<meta property="og:description" content="' . $description . '"/>';
?>
