How to access localhost website from another computer on the same network?

To access the localhost websites from another computers in a same network, need to follow these steps :
  1. Set up a virtual host
  2. Configure your hosts file
Set up a virtual host
You first need to set up a virtual host in your apache httpd-vhosts.conf file. On XAMP, you can find this file here: C:\xampp\apache\conf\extra\httpd-vhosts.conf This step prepares the Web server on your computer for handling symfony.local requests. You need to provide the name of the Virtual Host as well as the root/main folder of your website. To do this, add the following line at the end of that file. You need to change the DocumentRoot to wherever your main folder is. Here I have taken /Applications/MAMP/htdocs/Symfony/ as the root of my website.


<VirtualHost *:80>
    DocumentRoot "/Applications/MAMP/htdocs/Symfony/"
    ServerName symfony.local
</VirtualHost>

Configure your hosts file:

For the browser understand what symfony.local really means,
you need to edit the hosts file on your computer.

(if you're using WINDOWS 7, this file is in
 \Windows\system32\drivers\etc\hosts).



##
# Host Database
# localhost is used to configure the loopback interface
##
#...
127.0.0.1           symfony.local

Thats it. Now the configuration is completed.
Note: you should replace the above ip address with your system ip address.
Finally, you have to change the base secure and unsecure urls in
database at
core_config_data table.
Then your url will be change from http:localhost/project
to
http://127.0.0.1/project.

Warning: a form on this page has more than 1000 fields PHP MySql

Warning: a form on this page has more than 1000 fields PHP MySql


After reaching so many entries PhpMyAdmin started showing this warning:


Warning: a form on this page has more than 1000 fields. On submission, some of the fields might be ignored, due to PHP's max_input_vars configuration.


Solution:

For this, I have added the following lines at the bottom of php.ini file.

max_input_vars = 5000

suhosin.request.max_vars = 5000

suhosin.post.max_vars = 5000

Magento Vs Open cart

Magento Vs. Opencart – The similarities

Generally, Magento and OpenCart actually have a lot in common.

 1. They are both open source platforms that are ultimately designed to facilitate eCommerce activity.
 2. Both are developed in PHP and use templates to upload products, so they can be maintained by non-programmers.
 3. They are also rich in resources such as extensions, add-on products and plugins that can easily be added to them to support new functions.
 4. One of the greatest advantages that both Magento and Open Cart users enjoy is their ability to support multiple languages and currencies, making them a global solution that can suit businesses all around the world.

Some Market Share Figures

In terms of Market share,

 1. Magento is definitely bigger, with about 30% of top eCommerce websites being built on Magento, making it the largest eCommerce platform in the world.
 2. Open cart may be a lot smaller and newer on the market, but that doesn’t mean it falls in quality.
 3. Magento is the most popular open source e-commerce platform among sites ranking in the top 1,000,000 such websites in the world.
 4. Only when counting all open source e-commerce websites in the entire Internet does Magento fall to second behind Open Cart.

Hosting Plans and Options

 1. Open cart in this case will be cheaper to host thanks to its light weight, and will tend to work better for small to medium size stores.
 2. Magento performs better in hosting medium to large sized business websites.

Usage and Features

Magento :
  • Magento has been gaining world wide recognition for its ability to do just about anything you like and build the store of your dreams.
  • It offers highly customizable shopping experiences, unlimited design options, powerful SEO resources and unlimited plugins and integrations.
  • Every feature you can think of was probably built already and is available on MagentoCommerce. If its not on there, then surely a talented and certified Magento developer can create that solution for you.
  • With it’s flexibility comes also its complexity, which probably isn’t a problem if you’re a Magento developer and know what you’re doing. If you’re not a Magento developer or if you don’t know PHP, you’ll probably find Magento a bit too complex, especially when it comes to taking advantage of its flexibility and custom features.


OpenCart :

  • OpenCart on the other hand is a lot easier to program, but has a smaller community basis.
  • Its great for start-ups that need to deliver quickly without many integrations.
  •  It provides a powerful shopping cart and some great tools which are far more intuitive and straight forward, so much so that some professional developers may find it a bit too simplistic, with not enough features to play with. It’s a bit like comparing between WordPress and Wix, or Microsoft Office Picture Manager and Adobe Photoshop.


Community Support

Both Magento and OpenCart have well-established developer communities that offer support and advice by demand, but obviously the Magento community is far more robust. Magento also certifies and recommends developers to grant them with credibility, which makes it easy to filter the advice you receive and know who you should listen to. We expect that overtime, as Opencart continues to grow, more tutorials and resources will become available, and the number of users that can provide online support will increase.

Conclusion

 1. Magento is great for larger stores with larger budgets. Its got scale-ability to support the growth of your business for years to come, and support any need you may have in the future.
 2. Open cart is more suitable if you’re trying to build your store independently because its more intuitive, and its (almost) free to use, but take into consideration that one day, your business may grow out of it. Whichever your choose- we wish you luck with your new business!
