IV. filter

A filter is used to filter data.

1. filter types:

1) prefilter Prefilters

2) Postfilters

3) Output filter Output Filters

Based on the trigger time, the above three filters are divided

2. workflow

Tpl source file => Prefilter => compile tpl file => Postfilter => save to disk => run the compiled PHP file => Output Filters (=> if there is a smarty cache, output Filters content will be cached) => result Output.

3. Register a filter

In Smarty, the filter must be registered before use

In 2.6, register the filter

L Prefilters

$ Smarty-> register_prefilter ("func ");

L Postfilters

$ Smarty-> register_postfilter ("func ");

L Output Filters

$ Smarty-> register_outputfilter ("func ");

Register different filters to call different methods.

3.0, register the filter

$ Smarty-> registerFilter ($ type, $ callback );

$ Type: filter type

Value range:

Pre: Pre-filter

Post: Post filter

Output: Output filter

$ Callback: filter function

4. Code:

The pre-filter and post-filter will be executed during the first compilation, or the template will be executed again after the template changes.

The output filter is executed every time.
