Barand Posted December 9, 2019 Share Posted December 9, 2019 Only select check boxes (and radio buttons) are sent in the form data so you need you check if they are present using isset(). Example <?php for ($i=1; $i<=5; $i++) { if (isset($_GET['mycb'][$i])) { echo "Check box $i selected<br>" ; } } ?> <html> <head> <title>Example</title> </head> <body> <hr> <form> Check box 1 : <input type="checkbox" name="mycb[1]" value="1"><br> Check box 2 : <input type="checkbox" name="mycb[2]" value="2"><br> Check box 3 : <input type="checkbox" name="mycb[3]" value="3"><br> Check box 4 : <input type="checkbox" name="mycb[4]" value="4"><br> Check box 5 : <input type="checkbox" name="mycb[5]" value="5"><br><br> <input type="submit" name="btnSub" value="Submit"> </form> </body> </html> 1 Quote Link to comment Share on other sites More sharing options...
