Hi, this is the progress report for the cookie manager project which is currently part of GSoC.

In the 7th week of the program, we implemented the cookie block/unblock process using a system plugin.

Discussion Outline:

This week, we implemented the cookie block/unblock process which was discussed in this report (week 5) with some modifications in it.

Tasks completed this week:

• We have implemented a JavaScript-based solution for the cookie block/unblock process.
• Admin has to include all the cookie setting codes in the backend in the Cookie manager scripts section.
• On users’ first visit, scripts that require consent will not be rendered.
• Also, we block iframes, embeds, objects, links, and images that can set cookies on the first visit.
• All the scripts that are generating cookies, will be sent from backend to frontend using addScriptOptions, based on the user’s consent options.
• For blocking of iframes, embeds, links, we use regex to search for the particular iframes, links and change the attribute to block, according to its type.
• According to the consented category, required scripts will be executed.
• Scripts will be executed according to their position also.
• For executing scripts, we use document.createRange() to parse the script.
• Once users’ gave consent, we set a cookie for each category with its value true and false, cookie_category_[category]=true or cookie_category_[category]=false.
• When users set their preferences, then one cookie cookieBanner=shown will be set. All the cookie consent and cookie banner related information will be merged into one single cookie on a future update.
• Script codes will be sent from backend to frontend only if the cookie for that category has not been set.
• On subsequent visits, scripts will be rendered according to cookie cookie_category_[category].
• We use an output buffer with the str_replace function to replace the old content with the new content which includes scripts, according to its position.
• The cookie banner will be shown to the users only if cookieBanner=shown has not been set.
