Explanation of Programs 1 and 2
Program 1 will display the preferred check box input box (see picture). In the form input type check box, the name of each check box should be distinguished. Users can select more than one option. Pay attention to program 1 line 6-9! To retrieve the value of the check box type form, it should be checked first whether the check box is selected or not, using the isset () function. Note the 2nd row program. If check box is checked (selected) then take value from check box (row 5).
To see the result, open the browser then in the address bar type http://localhost/input07.php then enter. Then the result will look like the following.
That's the tutorial we can share about how to get input from checkbox in php. Hopefully these tutorials can add to our knowledge of php programming language.
