◆ filter()
filter_mathjaxloader::filter |
( |
| $text, |
|
|
array | $options = array() ) |
Override this function to actually implement the filtering.
Filter developers must make sure that filtering done after text cleaning does not introduce security vulnerabilities.
- Parameters
-
string | $text | some HTML content to process. |
array | $options | options passed to the filters |
- Return values
-
string | the HTML content after the filtering has been applied. |
Reimplemented from moodle_text_filter.
◆ insert_span()
filter_mathjaxloader::insert_span |
( |
| $text, |
|
|
| $start, |
|
|
| $end ) |
|
protected |
Wrap a portion of the $text inside a no link span ().
The whole text is then returned.
- Parameters
-
string | $text | The text to modify. |
int | $start | The start index of the substring in $text that should be wrapped in the span. |
int | $end | The end index of the substring in $text that should be wrapped in the span. |
- Return values
-
string | The whole $text with the span inserted around the defined substring. |
◆ setup()
filter_mathjaxloader::setup |
( |
| $page, |
|
|
| $context ) |
Setup page with filter requirements and other prepare stuff.
Override this method if the filter needs to setup page requirements or needs other stuff to be executed.
Note this method is invoked from {
- See also
- setup_page_for_filters()} for each piece of text being filtered, so it is responsible for controlling its own execution cardinality.
- Parameters
-
moodle_page | $page | the page we are going to add requirements to. |
context | $context | the context which contents are going to be filtered. |
- Since
- Moodle 2.3
Reimplemented from moodle_text_filter.
◆ wrap_math_in_nolink()
filter_mathjaxloader::wrap_math_in_nolink |
( |
| $text | ) |
|
|
protected |
Find math environments in the $text and wrap them in no link spans ().
If math environments are nested, only the outer environment is wrapped in the span.
The recognized math environments are [ ] and $$ $$ for display mathematics and ( ) for inline mathematics.
- Parameters
-
string | $text | The text to filter. |
- Return values
-
array | An array containing the potentially modified text and a boolean that is true if any changes were made to the text. |
