How to use

Register your account on OptiPic.io site.
Add your site on OptiPic CDN Control Panel.
Get your site ID from OptiPic CDN Control Panel sites list.
Download this lib to your site.
Use this library according use cases below

Administration area to install lib and configure it

After downloaded all code of this repository you may open admin area in your browser:

https://mydomain.com/optipic-cdn-php/admin/admin.php?key=b9k7o34rnfc5kco6m7fmjrts7u

Use case #1: Automatic convert image URLs using 'auto_prepend_file' php-directive

Inlude our /optipic-cdn-php/auto_prepend_file.php file in auto_prepend_file php.ini directive.

You may do it in .user.ini or php.ini or .htaccess.

Example using `.htaccess`

php_value auto_prepend_file "<SITE_ROOT_DIRECTORY>/optipic-cdn-php/optipic-cdn-php/auto_prepend_file.php"

Example using `php.ini` or `.user.ini`

; Automatically add files before PHP document.
; http://php.net/auto-prepend-file
auto_prepend_file = <SITE_ROOT_DIRECTORY>/optipic-cdn-php/optipic-cdn-php/auto_prepend_file.php

Hosting limitations to using `auto_prepend_file` php-directive

Some hostings allow you to set auto_prepend_file only upon request to support.
Examples of such hostings:

ukraine.com.ua (https://www.ukraine.com.ua/wiki/hosting/php/auto_prepend_file/)

Use case #2: Automatic convert image URLs using your site's entry point php-script

You may include our 1-line converter in on the top of your site's entry point (e.g. /index.php).

require_once __DIR__.'/optipic-cdn-php/optipic-cdn-php/ImgUrlConverter.php';

ob_start(array('\optipic\cdn\ImgUrlConverter', 'convertHtml'));

....
<YOUR ENTRY POINT LOGIC>
....

Use case #3: Manually using convert function of our lib in your code

You may use our lib to convert image URLs exactly where you want in your project to convert whole HTML-block contains image URLs.

$converterOptiPic = new \optipic\cdn\ImgUrlConverter(array(
    'site_id' => 99999999,                                       // your SITE ID from CDN OptiPic controll panel
    'domains' => array('mydomain.com', 'www.mydomain.com'),      // list of domains should replace to cdn.optipic.io
    'exclusions_url' => array('/test/test/index.php',),          // list of URL exclusions - where is URL should not converted
    'whitelist_img_urls' => array(),                             // whitelist of images URL - what should to be converted (parts or full urls start from '/')
    'srcset_attrs' => array('srcset', 'data-srcset'),            // tag's srcset attributes // @see https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images
));

$htmlConverted = $converterOptiPic->convertHtml($html);

Configuration

Option #1: Using file config.php in lib's root

File format:

return array(
    'site_id' => '0',                // your SITE ID from CDN OptiPic controll panel
    'domains' => array(),            // list of domains should replace to cdn.optipic.io
    'exclusions_url' => array(),     // list of URL exclusions - where is URL should not converted
    'whitelist_img_urls' => array(), // whitelist of images URL - what should to be converted (parts or full urls start from '/')
    'srcset_attrs' => array('srcset', 'data-srcset'), // tag's srcset attributes // @see https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images
);

In this case config will be automatic loaded in auto_prepend_file.php.

Option #2: Using ImgUrlConverter::loadConfig();

// Autoload config from config.php
ImgUrlConverter::loadConfig();

// Load config from custom config file
ImgUrlConverter::loadConfig('<path-to-your-config-file.php>');

// Load config from array
ImgUrlConverter::loadConfig(array(
    'site_id' => '0',                // your SITE ID from CDN OptiPic controll panel
    'domains' => array(),            // list of domains should replace to cdn.optipic.io
    'exclusions_url' => array(),     // list of URL exclusions - where is URL should not converted
    'whitelist_img_urls' => array(), // whitelist of images URL - what should to be converted (parts or full urls start from '/')
    'srcset_attrs' => array('srcset', 'data-srcset'), // tag's srcset attributes // @see https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images
));

Option #3: Pass config data into ImgUrlConverter::__constructor();

$converterOptiPic = new \optipic\cdn\ImgUrlConverter(array(
    'site_id' => 99999999,                                       // your SITE ID from CDN OptiPic controll panel
    'domains' => array('mydomain.com', 'www.mydomain.com'),      // list of domains should replace to cdn.optipic.io
    'exclusions_url' => array('/test/test/index.php',),          // list of URL exclusions - where is URL should not converted
    'whitelist_img_urls' => array(),                             // whitelist of images URL - what should to be converted (parts or full urls start from '/')
));

Option #1: Using file config.php in lib's root

If it does not work you also may create/edit file .user.ini in the site's root directory - alternative of php.ini file. https://www.php.net/manual/en/configuration.file.per-user.php

`ionCube` Warning

If you use ionCube on your site you shouldn't add auto_prepend_file direcive in php settings.
The ionCube does not support the directive auto_prepend_file and throws an error.
Instead, add the OptiPic connection directly to your site's entry point (usually an index.php) as stated above.

Example for `ImageCMS` (it's using `ionCube`)

Into index.php insert OptiPic logic before including core/CodeIgniter.php

// OptiPic
// --------------------------------------------------------------------
if(php_sapi_name() !== 'cli') {
    require_once __DIR__.'/optipic-cdn-php/optipic-cdn-php/ImgUrlConverter.php';
    ob_start(array('\optipic\cdn\ImgUrlConverter', 'convertHtml'));
}
// --------------------------------------------------------------------

/*
 * --------------------------------------------------------------------
 * LOAD THE BOOTSTRAP FILE
 * --------------------------------------------------------------------
 *
 * And away we go...
 *
 */
require_once BASEPATH . 'core/CodeIgniter.php';
