How do you checkbox is checked or not in php?

In our previous tutorials, we have performed various operations on different form elements using Javascript and jQuery. In this tutorial, our concern is to get values of multiple checked checkboxes using PHP as follows:

 To get  value of a checked checkbox :

Male
Female

To get value of multiple checked checkboxes, name attribute in HTML input type=”checkbox” tag must be initialize with an array, to do this write [ ] at the end of it’s name attribute :

C/C++

Java

PHP

In our example, there is a form contains some checkboxes, User checks them and when he/she hits submit button, multiple values of checkboxes will be display.

Watch our live demo or download our codes to use it.

Our example’s complete HTML and PHP codes are given below.

   I’m a newbee and have downloaded and modified your code. I have a webpage that offers 12-services [checkbox] and your “form” works fine and displays the name of the checkbox that was selected.

   I’d like to take the variable[s] selected to a new page and perform a mysql insert with some additional form data from that is on a new page. You’ve said the variables are “CRUD” but how do I get the selected checkbox info to a new page without losing the current value[s]?

   Do I do an echo somehow, on the new page, to know what was selected and then the mysql insert?

8. Thanks for the advice on this site. I am a beginner and I am working on a form that submits information into an email. The form is complete and everything is submitted to the email except the multiple checkbox selections. Initially it was just submitting 1 of the selected checkboxes. I added the [] to the check box names in the form and now I am getting a response of ‘array’ in the emailed results, so I believe its recognizing multiple selections but is just not listing them.
   I know I probably need to add more script to my PHP page that process the form so that it lists all of the selections, but I’m not sure what to add and where. Any advice would help me move closer to my goal. Thanks. And I am definitely bookmarking this site.
