PHP handler for vtigerCRM

Technical Assignment1. General Task A new corporate website needs to be created on WordPress for the domain sovbau.com and hosted on a new hosting instead of the current custom-built site. Domain: sovbau.com Current Site: custom-built site hosted on VPS/virtual server New Platform: WordPress New Hosting: regular hosting Main Language of the Site: German Additional Language: English Type of Site: corporate website of an electrical installation company, not an online store The site is currently hosted on a VPS/virtual server. A new site needs to be created on WordPress on new hosting, and after the development is completed, the domain sovbau.com should be switched from the current VPS to the new hosting. The old custom code does not need to be transferred. The current site should be used as: — a visual reference; — a source of important photos and materials; — a source of general information about the company. After the work is completed, the site owner should be able to independently edit texts, photos, services, projects, contact details, pages, gallery, and main blocks of the site through the WordPress admin panel.2. Corporate Email and DNS The corporate email will be hosted on a separate email hosting. There is no need to set up email on the site hosting. When connecting the new hosting, only DNS records related to the site can be changed, for example: — A record; — CNAME. It is not allowed to change or disrupt the operation of email DNS records: — MX; — SPF; — DKIM; — DMARC. Switching the site to new hosting should not disrupt the operation of corporate email.3. Main Scope of Work It is necessary to: Install and configure WordPress on the new hosting. Create a new corporate website on WordPress for the domain sovbau.com. During the development, host the new site at a technical address, subdomain, or temporary environment so that the current site continues to operate until the project is completed. After completion and verification of the new site, switch the domain sovbau.com from the current VPS/virtual server to the new hosting. Preserve and transfer important photos and materials from the old site. Organize the transferred photos and materials into a separate gallery. Make the German version of the site the main one. Create an additional English version of the site. Set up convenient switching between the German and English versions. Update contact details: use corporate addresses on the domain sovbau.com instead of Gmail. Create a modern corporate design for the electrical installation company. Ensure responsive display of the site on computers, tablets, and phones. Set up a contact form on the "Contact" page. Set up a separate request submission form via the button Anfrage senden. Configure the sending of messages and requests to the specified corporate email. Set up an SSL certificate so that the site opens correctly via HTTPS. Set up basic SEO based on the provided texts: — correct structure of H1 and H2 headings; — title and meta description for main pages; — human-readable URLs; — sitemap.xml; — robots.txt; — correct alt texts for images. Optimize the loading speed of the site. Set up protection for forms against spam. Set up the ability for independent editing through WordPress: — texts; — photos; — services; — projects and references; — contact details; — pages; — gallery; — blocks on the main page; — information on the "For Partners" page; — information on the "Career" page. After the work is completed, transfer all access and briefly explain how to independently edit the site.4. Design Requirements The new site should visually resemble the current site sovbau.com in overall style: — modern corporate appearance; — technical style; — dark or contrasting technical accents; — large informational blocks; — strict and clear structure; — professional presentation of services and completed projects. The old site does not need to be copied one-to-one. The design and structure of the current site can be reworked and improved.

After changing the PHP version from 7.0 to 7.4 on the OpenCart site, two elements have shifted slightly: the menu on the main page and the fields in the checkout process.

I want a bot for Telegram. Loading dialogues. With the help of AI, checking for potential lies. A website with advanced features. Registration, API, statistics, etc.

It is necessary to migrate the Opencart online store from PHP 7.4 to PHP 8.x. Currently, the core version is 3.0.3.8. We read that most likely the core will also need to be migrated to version 4.0 and there shouldn't be many difficulties... The functionality is mostly custom, and there are also Simple, OCFilter, Nova Poshta. We are waiting for recommendations and an approximate price. Ideally, someone who has already done similar work.

It is necessary to perform the update, transfer, and configuration of Laravel projects to a new server, ensuring stable operation, security, protection against exploits, and correct functioning of all services after migration. 1. Main tasks Prepare the new server for operation. Transfer project files, databases, configurations, and cron jobs. Update server software. Configure a secure environment for Laravel. Check compatibility of PHP, Laravel, Composer packages, and dependencies. Ensure protection against known exploits, malicious requests, and unauthorized access. Set up SSL certificates. Check the functionality of the websites after the transfer. 2. Transfer of Laravel projects For each project, it is necessary to: Transfer project files. Transfer the database. Transfer the .env configuration. Set directory access permissions: storage bootstrap/cache Check functionality: homepage; admin panel; authorization; forms; API; file uploads; email sending; cron jobs; queue workers.3. Security and protection It is necessary to implement basic and application-level protection: close root access via SSH; configure SSH access only via keys; change the default SSH port if necessary; configure the firewall; allow only necessary ports; install Fail2Ban; hide service versions of Nginx/Apache/PHP; restrict access to .env, .git, backup files, log files; set correct file permissions; check projects for malicious files; check Composer packages for known vulnerabilities; update dependencies if it does not break functionality; configure protection against SQL injection, XSS, CSRF, and path traversal; check the correctness of Laravel APP_ENV and APP_DEBUG; set APP_DEBUG=false in production; configure rate limiting for critical endpoints; check access to storage/uploads; configure protection against PHP execution in upload directories; check access rights to admin panels. 4. SSL and domains It is necessary to: Install SSL certificates. Configure automatic SSL renewal. Enable redirect from HTTP to HTTPS. Check the correct operation of websites via HTTPS. 5. Backup It is necessary to configure backup: project files; databases; .env files; uploaded media; cron configurations; Nginx/Apache configurations. Backup should be performed automatically on a schedule. It is preferable to store copies separately from the main server. 6. Post-transfer verification After migration, it is necessary to check: absence of 500/403/404 errors; absence of critical errors in Laravel logs. 9. Result of execution After the work is completed, there should be: Laravel projects successfully transferred to the new server; websites are functioning stably; SSL is configured; the server is protected with basic security settings; access to critical files is restricted; backup is configured; cron and queues are operational; the old server can be turned off after final verification.
