PHP-Codeigniter网址空间 [英] Php - Codeigniter url spaces

问题描述

我要尝试的是单击特定产品时，我想输入产品名称，而不是在我的网址中显示产品ID。
我今天要做的是base_url / controller / method / id

I'm trying to do is when i clicked my specific product, instead of the id of my product would appear in my url, i want to put the name of the product . what i did today is base_url/controller/method/id

我想做的是base_url / controller / method / product-name或base_url / controller / method / product_name

i want to do is base_url/controller/method/product-name or base_url/controller/method/product_name

，但是在我的代码中发生了什么事，我的产品名称中的所有空格都被％20占据了，我该怎么做才能用下划线或％代替％20破折号或以任何安全的方式在url中调用产品名称的方法。

but in my code what happened is in my product name all the spaces is occupied by %20 what should i do to replace the %20 by either underscore or dash or whatever safe way to call the product name in url.

以及我在该$ name（product_name）上获得的任何信息，我都会将其传递给我的模型。

and whatever i get on that $name(product_name) i will pass it to my model.

我的控制器

public function details($name){


    $prod_row = $this->PromoModel->getpromorow($name);
    $data['promodetail'] = $prod_row;

    $data['promo'] = $this->PromoModel->get_promo();

    $data['message']= "<h1> NO PROMOS AVAILABLE</h1>";
    $this->load->view('include/header',$data);
    $this->load->view('include/nav');
    $this->load->view('promo/PromoDetail', $data);
    $this->load->view('include/footer');
}

我的模型

public function getpromorow($name) {
    $this->db->where('name', $name);
    $query = $this->db->get('promo');
    return $query->row();
}

public function get_promo(){
    $query = $this->db->get('promo');
    return $query->result();
}

我的观点

<a href="<?= base_url(). 'promos/details/' . $promo_row->name ?>"> </a>

推荐答案

这应该可行，

  <a href="<?= base_url(). 'promos/details/' . str_replace(' ', '_', $promo_row->name); ?>"> </a>

就-与 _ 如果要路由到它们，例如说产品名称成为控制器中的方法，我认为PHP不允许-在方法名称中，但也不允许使用空格。.您可以使用 __ call（）作弊，但这是另一天的故事。

As far as - vs _ if you are routing to them, for example say that product name becomes a method in your controller, I don't think PHP allows - in method names, but it doesn't allow spaces either.. You can cheat using __call() but that's a other story for a different day.

如果它是一个参数，那么它应该没什么大不了的。

If its a parameter, then it shouldn't matter as much. Just if it is a method/function name.

-注意-这不是配置项特定的错误，请查看任何URL，告诉我是否在其中看到空格。

-Note- this is not a CI specific error, look at any url, tell me if you see spaces in them.

更新：作为建议，最好的方法是通过使用专用于url名称的字段（例如 slug 等），然后在制作新产品时对名称进行转换。然后，这是您可以控制的可编辑数据。例如，如果您的商品名称中带有-，该怎么办？这可能会引起问题。您可以通过为此单独准备一条数据来避免这种情况，它甚至可能像SKU编号等。设置起来需要做更多的工作，但从长远来看更易于维护。

UPdate: as a suggestion the best way to handle this is by having a field dedicated to the url name ( such as slug or such ) and when a new product is made just do the transform on the name. Then it's an editable piece of data you have control over. For example what if you have a product with a - in it's name. This will probably cause issues. You can avoid that by having a separate piece of data just for that, it could even be like a SKU number etc. It's more work to setup, but in the long run more maintainable.
