Field Replacements

Basic Replacements

The most basic template looks something like this:

{{Front}}

When you place text within curly brackets, Anki looks for a field by that name, and replaces the text with the actual content of the field.

Field names are case sensitive. If you have a field named Front, writing {{front}} will not work properly.

Your templates are not limited to a list of fields. You can also include arbitrary text on your templates. For example, if you’re studying capital cities, and you’ve created a note type with a “Country” field, you might create a front template like this:

What's the capital city of {{Country}}?

The default back template will look something like this:

{{FrontSide}}

<hr id=answer>

{{Back}}

This means “show me the text that’s on the front side, then a divider line, and then the Back field”.

The 'id=answer' part tells Anki where the divider is between the question and the answer. This allows Anki to automatically scroll to the spot where the answer starts when you press 'show answer' on a long card (especially useful on mobile devices with small screens). If you don’t want a horizontal line at the beginning of the answer, you can use another HTML element such as a paragraph or div instead.

Newlines

Card templates are like web pages, which means a special command is required to create a new line. For example, if you wrote the following in the template:

one
two

In the preview, you’d actually see:

one two

To add a new line, you need to add a <br> code to the end of a line, like so:

one<br>
two

The br code stands for "(line) br(eak)".

The same applies for fields. If you want to display two fields, one on each line, you would use

{{Field 1}}<br>
{{Field 2}}

Text to Speech for individual fields

This feature requires Anki 2.1.20, AnkiMobile 2.0.56 or AnkiDroid 2.17.

To have Anki read the Front field in a US English voice, you can place the following in your card template:

{{tts en_US:Front}}

On Windows, macOS, and iOS, Anki will use the OS’s built in voices. On Linux, no voices are built in, but voices can be provided by add-ons, such as this one.

To see a list of all available languages/voices, place the following on your card template:

{{tts-voices:}}

If there are multiple voices that support your chosen language, you can specify desired voices in a list, and Anki will choose the first available voice. For example:

{{tts ja_JP voices=Apple_Otoya,Microsoft_Haruka:Field}}

This would use Otoya when on an Apple device, and Haruka when on a Windows PC.

Specifying a different speed is possible in some TTS implementations:

{{tts fr_FR speed=0.8:SomeField}}

Both speed and voices are optional, but the language must be included.

On a Mac, you can customize the available voices:

  • Open the System Preferences screen.

  • Click on Accessibility.

  • Click on Speech.

  • Click on the system voice dropdown, and choose Customize.

Some voices sound better than others, so experiment to choose the one you prefer. Please note that the Siri voice can only be used by Apple apps. Once you’ve installed new voices, you’ll need to restart Anki for the new voices to become available.

On Windows, some voices like Cortana can not be selected, as Microsoft does not make those voices available to other applications.

On a cloze note type, you can make Anki read only the elided sections using the cloze-only filter, like so:

{{tts en_US:cloze-only:Text}}

The cloze-only filter is supported in Anki 2.1.29+, AnkiMobile 2.0.65+, and AnkiDroid 2.17+.

Text to Speech for multiple fields and static text

This feature requires Anki 2.1.50+, AnkiMobile 2.0.84+, or AnkiDroid 2.17+.

If you want TTS to read multiple fields or static text included in the template, you can use the following:

[anki:tts lang=en_US] This text should be read. Here is {{Field1}} and {{Field2}}[/anki:tts]

This is other text on the template. It is outside of the tags so it should not be read.

Special Fields

There are some special fields you can include in your templates:

The note's tags: {{Tags}}

The type of note: {{Type}}

The card's deck: {{Deck}}

The card's subdeck: {{Subdeck}}

The card's flag: {{CardFlag}}

The type of card ("Forward", etc): {{Card}}

The content of the front template
(only valid in back template): {{FrontSide}}

FrontSide will not automatically play any audio that was on the front side of the card. If you wish to have the same audio play automatically on both the front and back of the card, you’ll need to manually include the audio fields on the back as well.

As with other fields, special field names are case sensitive - you must use {{Tags}} rather than {{tags}} for example.

Hint Fields

It’s possible to add a field to the front or back of a card, but make it hidden until you explicitly show it. We call this a 'hint field'. Before adding a hint, please bear in mind that the easier you make it to answer a question in Anki, the less likely you are to remember that question when you encounter it in real life. Please have a read about the 'minimum information principle' on https://super-memory.com/articles/20rules.htm before proceeding.

First, you’ll need to add a field to store the hint in if you have not already. Please see the fields section if you’re not sure how to do this.

Assuming you’ve created a field called MyField, you can tell Anki to include it on the card but hide it by default by adding the following to your template:

{{hint:MyField}}

This will show a link labeled “show hint”; when you click it, the content of the field will be displayed on the card. (If MyField is empty, nothing will be shown.)

If you show the hint on the question and then reveal the answer, the hint will be hidden again. If you want to have the hint always revealed when the answer is shown, you will need to remove {{FrontSide}} from your back template and manually add the fields you wish to appear.

It is not currently possible to use a hint field for audio — the audio will play regardless of whether you’ve clicked on the hint link.

If you want to customize the appearance or behaviour, you’ll need to implement the hint field yourself. We can not provide any support for doing so, but the following code should get you started:

{{#Back}}
<a class=hint href="#"
onclick="this.style.display='none';document.getElementById('hint4753594160').style.display='inline-block';return false;">
Show Back</a><div id="hint4753594160" class=hint style="display: none">{{Back}}</div>
{{/Back}}

You can also use field replacement to create dictionary links. Imagine you’re studying a language and your favourite online dictionary allows you to search for text using a web URL like:

http://example.com/search?q=myword

You could add an automatic link by doing the following in your template:

{{Expression}}

<a href="http://example.com/search?q={{Expression}}">check in dictionary</a>

The template above would allow you to search for each note’s expression by clicking on the link while reviewing. There is a caveat however, so please see the next section.

HTML Stripping

Like templates, fields are stored in HTML. In the dictionary link example above, if the expression contained the word "myword" without any formatting, then the HTML would be the same: "myword". But when you include formatting in your fields, extra HTML is included. If "myword" was bolded for example, the actual HTML would be "<b>myword</b>".

This can present a problem for things like dictionary links. In the above example, the dictionary link would end up being:

<a href="http://example.com/search?q=<b>myword</b>">check in dictionary</a>

The extra characters in the link would likely confuse the dictionary site, and you’re likely not to get any matches.

To solve this, Anki provides the ability to strip formatting from fields when they are replaced. If you prefix a field name with text:, Anki will not include any formatting. So a dictionary link that worked even with formatted text would be:

<a href="http://example.com/search?q={{text:Expression}}">check in dictionary</a>

Right To Left Text

If you’re using a language that reads from right to left, you’ll need to adjust the template like so:

<div dir=rtl>{{FieldThatHasRTLTextInIt}}</div>

Ruby Characters

Some languages commonly use annotations above the text to display the pronunciation of characters. These annotations are known as ruby characters. In Japanese, these are known as furigana.

In Anki, you can display ruby characters by using the following syntax:

Text[Ruby]

Suppose the text above is written in MyField. By default, if you simply use {{Myfield}}, the field will be displayed as is. To properly position the ruby characters above the text, use the furigana filter in the templates like so:

{{furigana:MyField}}

Here are some examples:

Raw TextRendered Text
Text[Ruby]TextRuby
日本語[にほんご]日本語にほんご
世[よ]の 中[なか]世よの中なか
世[よ]の中[なか]世よの中なか (incorrect!)

Notice how the third example has a space before the 中 character. This is necessary to specify that the ruby text applies only to that character. If there was no space, the ruby text will be misplaced above the の character, as shown in the fourth example.

Additional Ruby Character Filters

In addition to the furigana filter, you can also only show certain parts of the ruby text, with the kana and kanji filters. The kana filter will only show the ruby text, while the kanji filter removes the ruby text entirely.

Raw TextField FilterRendered Text
日本語[にほんご]{{furigana:MyField}}日本語にほんご
日本語[にほんご]{{kana:MyField}}にほんご
日本語[にほんご]{{kanji:MyField}}日本語

These names are, again, borrowed from Japanese. The term kana represents the phonetic system used to describe how words are pronounced, whereas the term kanji represents its Chinese characters.

Media & LaTeX

Anki does not scan templates for media references, because it is slow to do so. This has implications for including media on the template.

Static Sounds/Images

If you wish to include images or sounds on your cards that are the same for every card (eg, a company logo at the top of each card):

  1. Rename the file so it starts with an underscore, e.g "_logo.jpg". The underscore tells Anki that the file is used by the template and it should be exported when sharing the deck.

  2. Add a reference to the media on your front or back template, like:

<img src="_logo.jpg">

Field References

Media references to fields are not supported. They may or may not display during review, and will not work when checking for unused media, importing/exporting, and so on. Examples that won’t work:

<img src="{{Expression}}.jpg">

[sound:{{Word}}]

[latex]{{Field 1}}[/latex]

Instead, you should include the media references in the field. Please see the importing section for more information.

Checking Your Answer

You can watch a video about this feature on YouTube.

The easiest way to check your answer is to click "Basic" at the top left of the card adding screen, and select "Basic (type in the answer)".

If you have downloaded a shared deck and would like to type in the answer with it, you can modify its card template. If it has a template like:

{{Native Word}}

{{FrontSide}}

<hr id=answer>

{{Foreign Word}}

To type in the foreign word and check if you are correct, you need to edit your front template so that it looks like this:

{{Native Word}}
{{type:Foreign Word}}

Note that we have added type: in front of the field we want to compare. Since FrontSide is on the back of the card, the type answer box will appear on the back as well.

When reviewing, Anki will display a text box where you can type in the answer, and upon hitting Enter or showing the answer, Anki will show you which parts you got right and which parts you got wrong. The text box’s font size will be the size you configured for that field (via the “Fields” button when editing).

This feature does not change how the cards are answered, so it’s still up to you to decide how well you remembered or not.

Only one typing comparison can be used on a card. If you add the above text multiple times, it will not work. It also only supports a single line, so it is not useful for comparing against a field that is comprised of multiple lines.

Anki uses a monospaced font for the answer comparison so that the “provided” and “correct” sections line up. If you wish to override the font for the answer comparison, you can put the following at the bottom of your styling section:

code#typeans { font-family: "myfontname"; }

Which will affect the following HTML for the answer comparison:

<code id=typeans>...</code>

Advanced users can override the default type-answer colors with the css classes 'typeGood', 'typeBad' and 'typeMissed'. AnkiMobile supports 'typeGood' and 'typeBad', but not 'typeMissed'.

If you wish to override the size of the typing box and don’t want to change the font in the Fields dialog, you can override the default inline style using !important, like so:

#typeans { font-size: 50px !important; }

It is also possible to type in the answer for cloze deletion cards. To do this, add {{type:cloze:Text}} to both the front and back template, so the back looks something like this:

{{cloze:Text}}
{{type:cloze:Text}}
{{Extra}}

Note that since the cloze type does not use FrontSide, this must be added to both sides on a cloze note type.

If there are multiple sections elided, you can separate the answers in the text box with a comma.

Type answer boxes will not appear in the "preview" dialog in the browser. When you review or look at the preview in the card types window, they will display.

Type answer boxes will not be displayed when you review your cards on ankiweb.net.
