Use JavaScript by adding an onChange attribute to your input tags  lt input onChange  quot this form submit   quot        gt

I ve been messing around with this for about four hours and decided to share this with you   You can submit a form by clicking a checkbox but the weird thing is that when checking for the submission in php  you would expect the form to be set when you either check or uncheck the checkbox  But this is not true  The form only gets set when you actually check the checkbox  if you uncheck it it won t be set   the word checked at the end of a checkbox input type will cause the checkbox to display checked  so if your field is checked it will have to reflect that like in the example below  When it gets unchecked the php updates the field state which will cause the word checked the disappear   You HTML should look like this    lt form method  post  action     gt   lt input type  checkbox  name  checkbox  onChange  submit      lt  php if  page- gt checkbox state    1    echo  checked       gt  gt   lt  form gt    and the php   if isset   POST  checkbox             the checkbox has just been checked        save the new state of the checkbox somewhere     page- gt checkbox state    1    else         the checkbox has just been unchecked       if you have another form ont the page which uses than you should       make sure that is not the one thats causing the page to handle in input       otherwise the submission of the other form will uncheck your checkbox       so this this line is optional        if  isset   POST  submit                  page- gt checkbox state    0

You can submit form by just clicking on checkbox by simple method in JavaScript  Inside form tag or Input attribute add following attribute      onchange  quot this form submit   quot   Example   lt form gt         lt div gt              lt input type  quot checkbox quot  gt         lt  div gt   lt  form gt

Yes  this is possible    lt form id  formName  action   lt  php echo   SERVER  PHP SELF     gt   method  get  gt       lt input type   checkbox  name  cBox    value    3  onchange  document getElementById  formName   submit    gt 3 lt  input gt       lt input type   checkbox  name  cBox    value    4  onchange  document getElementById  formName   submit    gt 4 lt  input gt       lt input type   checkbox  name  cBox    value    5  onchange  document getElementById  formName   submit    gt 5 lt  input gt       lt input type  submit  name  submit  value  Search    gt   lt  form gt    By adding onchange  document getElementById  formName   submit    to each checkbox  you ll submit any time a checkbox is changed   If you re OK with jQuery  it s even easier  and unobtrusive      document  ready function            formname   on  change    input checkbox   function                formname   submit                  For any number of checkboxes in your form  when the  change  event happens  the form is submitted   This will even work if you dynamically create more checkboxes thanks to the  on   method

Submit form when your checkbox is checked   document  ready function            quot  yoursubmitbuttonid quot   click function                               if     quot  yourcheckboxclass quot   is  quot  checked quot                                              quot  yourformId quot   submit                      else                      alert  quot Please select     quot                        return false                                    return false

document  ready      function                    input checkbox   change              function                                 if    this  is   checked                                               formName   submit                                                         Though it would probably be better to add classes to each of the checkboxes and do      checkbox class   change      so that you can choose which checkboxes submit the form instead of all of them doing it
