input"title" 自动生成一个 slug 将发送到列 slug_url 和 slug_link，我需要在 slug_url.

我想在生成到列 slug_url 的 slug 上添加默认值 url。

示例：

我想将此 url 添加为生成的 slug 的默认值“http://example.com/”

这是 slug-gererated-to-the-column-slug-url

这是它应该如何发送到我的专栏 slug_url:

http://example.com/this-is-the-slug-gererated-to-the-column-slug-url

Answer 1

很简单，改一下这部分代码就可以了：

$insert_data = array(

    ':title'      => $_POST['title'],
    ':descricao'  => $_POST['descricao'],
    ':capa'       => $_POST['capa'],
    ':alt'        => $_POST['alt'],
    ':keywords'   => $_POST['keywords'],
    ':categoria'  => $_POST['categoria'],
    ':slug_url'   => "https://example.com/$slug",
    ':slug_link'  => $slug,
    ':entry_type' => $_POST['entry_type'],

  );

注意我刚刚更改了设置 :slug_url 列的行

Answer 2

你可以添加这样的东西

':slug_url' => "https://example.com/".$slug,
