ci-markdown's Introduction

CI Markdown

CI Markdown is a modified rendition of Michel Fortin's PHP Markdown and PHP Markdown Extra for CodeIgniter.

Install

Requirements

PHP version 5.4.8 or newer
CodeIgniter version 2.x – v3.x

Download

Download and extract the zip release to your CoddeIgniter application/libraries/ directory.

The extracted path should resemble:

application/libraries/Markdown.php

Usage

Configuration

Custom PHP Markdown settings are defined in the config/markdown.php config file.

Initializing the Markdown Class

Like most other classes in CodeIgniter, initialize it from your controller using the $this->load->library() method:

$this->load->library('markdown');

To programmatically configure the Markdown instance, overriding any matched settings defined in the config file:

$config = array(
    'tab_width' => 2,
    'no_markup' => true,
    'empty_element_suffix' => '/>'
);

$this->load->library('markdown', $config);

Markdown to HTML

$this->markdown->transform()

Accepts a single string parameter of Markdown text and returns the transformed HTML.

$this->load->library('markdown');

$markdownText = "# Heading "."\n"."## Sub-heading";
echo $this->markdown->transform($markdownText);
// <h1>Heading</h1>
// <h2>Sub-heading</h2>

Markdown file to HTML

$this->markdown->transform_file()

Accepts a single string parameter for a Markdown file path and returns the transformed HTML.

$this->load->library('markdown');

echo $this->markdown->transform_file('/path/to/markdown/file.md');
// <h1>Heading</h1>
// <h2>Sub-heading</h2>

Cross Site Scripting Vulnerabilty

The parser allows you to create links with a source such as javascript:alert('xss'), this could lead to cross site scripting vulnerabilities when a content security policy is not in use. Thoughts?

Error when calling parse in view file

I keep running into this error

A PHP Error was encountered

Severity: Notice

Message: Undefined property: CI_Loader::$markdown

Filename: views/view_article.php

Line Number: 68

I am saving the Markdown data in a database and pulling that from the database and displaying in my code like this:

$string = $a->body;
$this->load->library('markdown');
echo $this->markdown->parse($string);

As soon as I remove "echo $this->markdown->parse($string);", I get no errors.

Any suggestions would help.

How to replace specific <span> like actually with <abbr>?

I'd like to explain some words, but they are not abbreviations, so it's wrong to explain these words with <abbr title="">

I just would like to reproduce the system of abbrs but with some changes and only to certain <span>, any idea how to proceed?

I read the code a bit but it looked very confusing, with meaningless names etc

Fatal error: Class declarations may not be nested in /.../libraries/Markdown.php on line 1475

Hi, i got this error whem i trying to load your lib.. what's wrong?

Request: Sample of Markdown Preview

Hello @jonlabelle ,

Can you please create a sample of markdown preview?
I can't make one. I tried the way of passing javascript variable to PHP but still not working.

Happy New Year!

Issue with markdown transform of nested lists

Hi,

From some articles I have read, it appears that the markdown standard has issues with code blocks and nested lists: the two are getting mixed up, so nested lists are styled the way code blocks would be styled.

The advice of the people on the forum is to use two spaces instead, but that makes it render as a paragraph.

To test it out:

$this->markdown->transform('  1.1. Hello');
$this->markdown->transform('    1.1. Hello');

You will see that the first one renders in a paragraph tag and the second one as a code block.

I guess it can be disputed as to where the issue lies (with the renderer or with markdown itself) but I figured that, since this issue is almost 10 years old, the markdown syntax won't be fixed (if it is at fault).

Is there something you can do about it?

Btw I didn't know all the possibilities of markdown-extra until i read carefully the original site. Might be interesting to put a more elaborate example.

# Heading

## Subheading with ID {#my_header}

### Subsubheading with class {.my_class}

<div style="color: purple" markdown=1>
    <http://google.com>
</div>

_italic_ **bold**

Abbreviations improvement

Predefined abbreviations are very useful but they don't work in specific cases:

if the abbreviation is singular, then the plural form won't be detected as an abbr. There could be a way to define this per abbreviation eventually? atm forced to duplicate each abbr
If the abbreviation has one uppercase character, then it won't be detected, but sometimes acronyms have weird casing, or putting an abbr on a simple word which is the first word in a sentence means it won't be detected

Syntax highlighting

Hey,
currently there is no syntax highlighting supported.
Will you add this feature?

Usage:

var s = "JavaScript syntax highlighting";
alert(s);

If you decide to bind MySQL to your public IP, you should implement firewall rules that only allow connections from specific IP addresses.

And the library translate it to:

<p>{: .note}
></p>

<blockquote>

Any solution to return a <blockquote class="note">...?

Thank you! 😃
