Yield

Contents

Syntax

<txp:yield />

The yield tag can be used as either a single tag or a container tag to return the inner content of the enclosing <txp:output_form /> tag.

The tag works in unison with the output_form tag; You place a <txp:yield /> tag in a form and then wherever you use that form the content wrapped inside the output_form tag gets placed where the yield tag was. Essentially, the value of this is that you can use forms as flexible building blocks - each building block has a common structure, but individualized content.

Attributes

Tag will accept the following attributes (case-sensitive) as well as the global attributes :

default="string" v4.7.0+
The default value (see examples below). If unset, the enclosed content (if any) will be used.
Default: unset.
name="string" v4.7.0+
The name (see examples below).
Default: unset.

Examples

Example 1: Inner content and custom attributes

Given the following form named example_form:

<div>
    This content is static and will be the same every time this form is <txp:yield name="verb" default="invoked" />.
    <txp:yield />
</div>

We can invoke it twice (either in long or short form) with different inner content and attributes each time:

<txp:output_form form="example_form">
    Invoking 'example_form' with some inner content.
</txp:output_form>
<txp::example_form verb="called">
    Invoking 'example_form' again, this time with different inner content.
</txp::example_form>

And the result will be:

<div>
    This content is static and will be the same every time this form is invoked.
    Invoking 'example_form' with some inner content.
</div>
<div>
    This content is static and will be the same every time this form is called.
    Invoking 'example_form' again, this time with different inner content.
</div>

Other tags used: output_form.
