PHP Multiple Checkbox Array

Question

I ve looked around for a few examples here but a lot of them are either too advanced for my grasp of PHP or their examples are too specific to their own projects  I am currently struggling with a very basic part of a PHP form   I am trying to create a form with a few checkboxes  each assigned a different value  I want these to be sent to a variable  array   that I can echo use later  in my case I will be sending the checked values in an email   So far  I have tried a few variations  but the closest I have come to it is this      lt form method  post  id  userform  action  thisform php  gt   lt tr gt       lt td gt Trouble Type lt  td gt       lt td gt       lt input type  checkbox  name  checkboxvar  value  Option One  gt 1 lt br gt       lt input type  checkbox  name  checkboxvar  value  Option Two  gt 2 lt br gt       lt input type  checkbox  name  checkboxvar  value  Option Three  gt 3      lt  td gt   lt  tr gt   lt  table gt   lt input type  submit  class  buttons  gt   lt  form gt    lt  php  checkboxvar       REQUEST  checkboxvar      gt    Where I d echo  checkboxvar   into my email  Am I going about this completely wrong  The other idea I had was to use a lot of if statements

lt form method  post  id  userform  action  thisform php  gt   lt tr gt       lt td gt Trouble Type lt  td gt       lt td gt       lt input type  checkbox  name  checkboxvar    value  Option One  gt 1 lt br gt       lt input type  checkbox  name  checkboxvar    value  Option Two  gt 2 lt br gt       lt input type  checkbox  name  checkboxvar    value  Option Three  gt 3      lt  td gt   lt  tr gt   lt  table gt   lt input type  submit  class  buttons  gt   lt  form gt    lt  php  if  isset   POST  checkboxvar            print r   POST  checkboxvar          gt    You pass the form name as an array and then you can access all checked boxes using the var itself which would then be an array   To echo checked options into your email you would then do this   echo implode        POST  checkboxvar        change the comma to whatever separator you want   Please keep in mind you should always sanitize your input as needed   For the record  official docs on this exist  http   php net manual en faq html php faq html arrays

Also remember you can include custom indices to the array sent to the server like this   lt form method  post  id  userform  action  thisform php  gt   lt tr gt       lt td gt Trouble Type lt  td gt       lt td gt       lt input type  checkbox  name  checkboxvar 4   value  Option One  gt 4 lt br gt       lt input type  checkbox  name  checkboxvar 6   value  Option Two  gt 6 lt br gt       lt input type  checkbox  name  checkboxvar 9   value  Option Three  gt 9      lt  td gt   lt  tr gt   lt input type  submit  class  buttons  gt   lt  form gt    This is particularly useful when you want to use the id of individual objects in a server array accounts  for instance  to send data back to the server and recognize same at server    lt form method  post  id  userform  action  thisform php  gt   lt tr gt       lt td gt Trouble Type lt  td gt       lt td gt       lt  php foreach  accounts as  account      gt           lt input type  checkbox  name  accounts  lt  php echo  account- gt id   gt    value   lt  php echo  account- gt name   gt   gt           lt  php echo  account- gt name   gt           lt br gt       lt  php     gt       lt  td gt   lt  tr gt   lt input type  submit  class  buttons  gt   lt  form gt    lt  php  if  isset   POST  accounts            print r   POST  accounts          gt

You need to use the square brackets notation to have values sent as an array    lt form method  post  id  userform  action  thisform php  gt   lt tr gt       lt td gt Trouble Type lt  td gt       lt td gt       lt input type  checkbox  name  checkboxvar    value  Option One  gt 1 lt br gt       lt input type  checkbox  name  checkboxvar    value  Option Two  gt 2 lt br gt       lt input type  checkbox  name  checkboxvar    value  Option Three  gt 3      lt  td gt   lt  tr gt   lt  table gt   lt input type  submit  class  buttons  gt   lt  form gt    Please note though  that only the values of only checked checkboxes will be sent
