How to display an image stored as a page resource when the image is an element of an array of objects?

php editor Zimo would like to share with you a question about image display: when the image is an element of an object array, how to display the image stored as a page resource? This is a common problem, especially in scenarios that deal with image uploading and display. In PHP, we can display images by using HTML's tag, and combined with PHP's loop and output statements, we can easily traverse the object array and display the image on the page. Below is a simple sample code to help you understand how to implement this function. First, we assume that there is already an object array $images, which stores information about multiple images, including the path and name of the image. Next, we can use a foreach loop to traverse the array, use the echo statement in the loop to output the tag, and set the src attribute to the path of the image. This way, when the page loads, all images will be displayed automatically. I hope this simple example can help everyone solve similar problems. If you have other questions, please leave a message for discussion.

Question content

The image in my front page is stored like this:

images:
  - image: image_1.jpg
    caption: "image 1 caption"
  - image: image_2.jpg
    caption: "image 2 caption"

I only want to show the first one, so I use the following:

{{ $image := .resources.getmatch (printf "**%s" (index .params.images 0).image) }}

Strangely, this only works if I add the .image section when running on my local hugo server. Once I stop and start again the site fails to rebuild with the following error:

... execute of template failed: template: partials/content/figure.html:7:70: executing "partials/content/figure.html" at <0>: can't evaluate field image in type string

I just want to be able to access images[0].image. How can I do this?

Workaround

It turns out that I have some other content types where the preceding images are still simple arrays, not arrays of objects. This resulted in a build error for me. To solve this problem, I used the following suggestions, here:

{{ $image := "" }}
{{ if reflect.IsMap (index .Params.images 0) }}
  {{ $image = .Resources.GetMatch (printf "**%s" (index .Params.images 0).image) }}
{{ else }}
  {{ $image = .Resources.GetMatch (printf "**%s" (index .Params.images 0)) }}
{{ end }}
