Block functions are functions of the form: `{func} .. {/func}`. In other
|
|
words, they enclose a template block and operate on the contents of this
|
|
block. Block functions take precedence over [custom
|
|
functions](#language.custom.functions) of the same name, that is, you
|
|
cannot have both custom function `{func}` and block function
|
|
`{func}..{/func}`.
|
|
|
|
- By default your function implementation is called twice by Smarty:
|
|
once for the opening tag, and once for the closing tag. (See
|
|
`$repeat` below on how to change this.)
|
|
|
|
- Starting with Smarty 3.1 the returned value of the opening tag call
|
|
is displayed as well.
|
|
|
|
- Only the opening tag of the block function may have
|
|
[attributes](#language.syntax.attributes). All attributes passed to
|
|
template functions from the template are contained in the `$params`
|
|
variable as an associative array. The opening tag attributes are
|
|
also accessible to your function when processing the closing tag.
|
|
|
|
- The value of the `$content` variable depends on whether your
|
|
function is called for the opening or closing tag. In case of the
|
|
opening tag, it will be NULL, and in case of the closing tag it will
|
|
be the contents of the template block. Note that the template block
|
|
will have already been processed by Smarty, so all you will receive
|
|
is the template output, not the template source.
|
|
|
|
- The parameter `$repeat` is passed by reference to the function
|
|
implementation and provides a possibility for it to control how many
|
|
times the block is displayed. By default `$repeat` is TRUE at the
|
|
first call of the block-function (the opening tag) and FALSE on all
|
|
subsequent calls to the block function (the block\'s closing tag).
|
|
Each time the function implementation returns with `$repeat` being
|
|
TRUE, the contents between `{func}...{/func}` are evaluated and the
|
|
function implementation is called again with the new block contents
|
|
in the parameter `$content`.
