Page resources are available for [page bundles]({{< relref "/content-management/page-bundles" >}}) only,
i.e. a directory with either a `index.md`, or `_index.md` file at its root. Resources are only attached to
the lowest page they are bundled with, and simple which names does not contain `index.md` are not attached any resource.
## Properties
ResourceType
: The main type of the resource. For example, a file of MIME type `image/jpeg` has the ResourceType `image`.
Name
: Default value is the filename (relative to the owning page). Can be set in front matter.
Title
: Default value is the same as `.Name`. Can be set in front matter.
Permalink
: The absolute URL to the resource. Resources of type `page` will have no value.
RelPermalink
: The relative URL to the resource. Resources of type `page` will have no value.
Content
: The content of the resource itself. For most resources, this returns a string with the contents of the file. This can be used to inline some resources, such as `<script>{{ (.Resources.GetMatch "myscript.js").Content | safeJS }}</script>` or `<img src="{{ (.Resources.GetMatch "mylogo.png").Content | base64Encode }}">`.
MediaType
: The MIME type of the resource, such as `image/jpeg`.
MediaType.MainType
: The main type of the resource's MIME type. For example, a file of MIME type `application/pdf` has for MainType `application`.
MediaType.SubType
: The subtype of the resource's MIME type. For example, a file of MIME type `application/pdf` has for SubType `pdf`. Note that this is not the same as the file extension - PowerPoint files have a subtype of `vnd.mspowerpoint`.
MediaType.Suffixes
: A slice of possible suffixes for the resource's MIME type.
## Methods
ByType
: Returns the page resources of the given type.
```go
{{ .Resources.ByType "image" }}
```
Match
: Returns all the page resources (as a slice) whose `Name` matches the given Glob pattern ([examples](https://github.com/gobwas/glob/blob/master/readme.md)). The matching is case-insensitive.
```go
{{ .Resources.Match "images/*" }}
```
GetMatch
: Same as `Match` but will return the first match.
### Pattern Matching
```go
// Using Match/GetMatch to find this images/sunset.jpg ?
.Resources.Match "images/sun*" ✅
.Resources.Match "**/sunset.jpg" ✅
.Resources.Match "images/*.jpg" ✅
.Resources.Match "**.jpg" ✅
.Resources.Match "*" 🚫
.Resources.Match "sunset.jpg" 🚫
.Resources.Match "*sunset.jpg" 🚫
```
## Page Resources Metadata
The page resources' metadata is managed from the corresponding page's front matter with an array/table parameter named `resources`. You can batch assign values using [wildcards](http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm).
{{% note %}}
Resources of type `page` get `Title` etc. from their own front matter.
{{% /note %}}
name
: Sets the value returned in `Name`.
{{% warning %}}
The methods `Match` and `GetMatch` use `Name` to match the resources.
{{%/ warning %}}
title
: Sets the value returned in `Title`
params
: A map of custom key/values.
### Resources metadata example
{{< code-toggle copy="false">}}
title: Application
date : 2018-01-25
resources :
- src : "images/sunset.jpg"
name : "header"
- src : "documents/photo_specs.pdf"
title : "Photo Specifications"
params:
icon : "photo"
- src : "documents/guide.pdf"
title : "Instruction Guide"
- src : "documents/checklist.pdf"
title : "Document Checklist"
- src : "documents/payment.docx"
title : "Proof of Payment"
- src : "**.pdf"
name : "pdf-file-:counter"
params :
icon : "pdf"
- src : "**.docx"
params :
icon : "word"
{{</ code-toggle >}}
From the example above:
- `sunset.jpg` will receive a new `Name` and can now be found with `.GetMatch "header"`.
- `documents/photo_specs.pdf` will get the `photo` icon.
- `documents/checklist.pdf`, `documents/guide.pdf` and `documents/payment.docx` will get `Title` as set by `title`.
- Every `PDF` in the bundle except `documents/photo_specs.pdf` will get the `pdf` icon.
- All `PDF` files will get a new `Name`. The `name` parameter contains a special placeholder [`:counter`](#the-counter-placeholder-in-name-and-title), so the `Name` will be `pdf-file-1`, `pdf-file-2`, `pdf-file-3`.
- Every docx in the bundle will receive the `word` icon.
{{% warning %}}
The __order matters__ --- Only the **first set** values of the `title`, `name` and `params`-**keys** will be used. Consecutive parameters will be set only for the ones not already set. In the above example, `.Params.icon` is first set to `"photo"` in `src = "documents/photo_specs.pdf"`. So that would not get overridden to `"pdf"` by the later set `src = "**.pdf"` rule.

### The `:counter` placeholder in `name` and `title`
The `:counter` is a special placeholder recognized in `name` and `title` parameters `resources`.
The counter starts at 1 the first time they are used in either `name` or `title`.
For example, if a bundle has the resources `photo_specs.pdf`, `other_specs.pdf`, `guide.pdf` and `checklist.pdf`, and the front matter has specified the `resources` as:
{{< code-toggle copy="false">}}
[[resources]]
src = "*specs.pdf"
title = "Specification #:counter"
[[resources]]
src = "**.pdf"
name = "pdf-file-:counter"
{{</ code-toggle >}}
the `Name` and `Title` will be assigned to the resource files as follows:
| Resource file | `Name` | `Title` |
|-------------------|-------------------|-----------------------|
| checklist.pdf | `"pdf-file-1.pdf` | `"checklist.pdf"` |
| guide.pdf | `"pdf-file-2.pdf` | `"guide.pdf"` |
| other\_specs.pdf | `"pdf-file-3.pdf` | `"Specification #1"` |
| photo\_specs.pdf | `"pdf-file-4.pdf` | `"Specification #2"` |
