</div>

I have customized “.Params.ct\_download\_link” and “.Params.clic\_download\_link” in “single.html”, but each article header can only use “ct\_download\_link” and “.Params.clic\_download\_link” to pass only one link. How can I make “ct\_download\_link1”, "ct\_download\_link2"and “.Params.clic\_download\_link1” “.Params.clic\_download\_link2”… The cycle is called when publishing, that is, the same page outputs multiple different links

Sorry, it’s hard to understand what you’re asking. Are you saying you want to put the URLs in your frontmatter in an array, so you can loop through them in your template?

On the markdown content file frontmatter, something like this? :

```auto
---
...
myurls: 
   - http://oneurl.com
   - https://twourl.net
...
---

```

… and you want to “loop through” those, in your single.html?

Ok, I see. You are getting errors? It’s possible that what you did will work if _every_ page that is rendered by your single has that parameter. If not, `hugo server` will give an error, usually because some are missing.

You can use `with` to fix this. It acts like an `if then` statement.

> **[with](https://gohugo.io/functions/with#readout)**
>
> Rebinds the context (\`.\`) within its scope and skips the block if the variable is absent.

```auto
...href="{{ with .Params.cd_download_link }}{{ . }}{{ end }}">...

```

Ah, ok. You’re telling hugo to go find a param `clic_download_link` but, not specifying it in your frontmatter. It won’t act like a wildcard.

If you want to make a list of urls of a certain type, you need to use `range` to loop over the urls and put them in like I mentioned first above.

You’re looking to show, say, a list of “ct” type links and another list of “clic” type links? An example from a single.html:

```auto
<p class="menu-label has-text-esolia-secondary-2-0">Tags</p>
  <div class="tags has-margin-l">{{ range .Params.tags }}
   <span class="tag is-rounded is-light"><a href="{{ "/tags/" | relLangURL }}{{ . | urlize }}">{{ . }}</a></span>{{ end }}
  </div>

```

… given frontmatter like:

```auto
tags:
  - this
  - that

```

This just puts the tags I have in the frontmatter, in spans, between a div.

</div>

In fact, I just want to do a download of the historical version of the list, a version number corresponds to the download link for each disk, the other version number is still those disks, but it’s another version of the download link, so I need to be the same ct\_download\_link distinguishes 1 2 3 4 5… to distinguish different versions of download links

Sorry, not so sure what you want now. Do you mean you want to show the latest/last URL in the list only, but still have the others available? If so, you could adapt this:

> [@Howto: Delimiter separated tags](https://discourse.gohugo.io/t/howto-delimiter-separated-tags/146):
>
> The construction below looks counter-intuitive, but it works: Given: Tags = ['item1', 'item2', 'item3'] This: {{ range $i, $e := .Params.tags }}{{ if $i }}, {{ end }}{{ $e }}{{ end }} Gives: item1, item2, item3 The example above uses tags with comma as delimiter, but this of course also applies to other ranges and delimiters.

So, instead of showing the comma you show the last listed URL.

just like this screenshots

version,update date,download link  
one row every version, one to one correspondence

Take clicknUpload for example,version number 3.0,update date 2018.4.29,ClicknUpload download link in one row,add version number 3.1,update date 2018.4.30,ClicknUpload download link in one row, row and row correspondence
