Forms that are based on this form template must be filled out by using Microsoft Office InfoPath. If the form will be filled out by using a Web browser, the form cannot submit data to a database directly. To configure a browser-compatible form template to submit data to a database, use a data connection that submits data to a Web service that works with the database.

The primary database table that is used in the main data connection contains a primary key, unique constraint, or unique index. Any other database tables that are used with this main data connection have a simple relationship to the primary database table.

If the database meets these requirements, InfoPath enables the submit data connection and adds a Submit button to the Standard toolbar and a Submit command to the File menu on the form. You can choose to disable the submit data connection in the wizard when you design a form template that is based on a database.

If you disable the submit data connection in the wizard and then later you decide that you want to use this submit data connection, you can enable the submit data connection by modifying the main data connection.

For one thing, visitors today expect lightning-fast loading times with every click. This can lead to less organic traffic. If you want to see how dramatic these speed changes can be, consider trying an experiment. You might find that your site is not performing as well as it could.

Then, update your PHP and retest. You may be surprised at just how big of an impact this single action can have. Updating your PHP is well worth the effort in terms of speed alone. Safeguarding user data can protect it against malicious actors looking for access.

Doing this can be especially important if you handle sensitive information like credit card numbers. Updating your PHP version is a simple yet effective way to maintain a strong layer of security. One reason for this is potential security weaknesses. Just like with WordPress, plugins, and themes, developers will release patches to fix any vulnerabilities. Still, keep in mind that PHP is an open-source language.

While this is often a fantastic way to encourage development within the community, it also comes with a downside: anyone can modify the code, including hackers. As they find new ways to infiltrate your PHP code, developers react by creating more secure versions.

You can think of your PHP version as one of many layers of security. Unfortunately, no single protection method is perfect. This, in turn, can cause your site to crash, damaging the user experience and potentially affecting your search engine rankings. Updates can help correct this issue by optimizing your use of server resources. You might also avoid hiccups that can happen if the version is not compatible with your plugins or theme. Additionally, as we covered before, updates are crucial to security.

Having to recover from an attack can mean being offline for a long time. A step towards a safer site is also a step towards a more stable one. Fortunately, WordPress is a fairly user-friendly platform. Its developers have included several measures to help you keep your website in top shape.
