It s pretty simple  Pay attention and you ll get it right away      You will create a html array  which will be then sent to php array  Your html code will look like this    lt input type  checkbox  name  check list 1   alt  Checkbox  value  checked  gt   lt input type  checkbox  name  check list 2   alt  Checkbox  value  checked  gt   lt input type  checkbox  name  check list 3   alt  Checkbox  value  checked  gt    Where  1   2   3  are the IDs of your messages  meaning that you will echo your  row  Report ID   in their place   Then  when you submit the form  your PHP array will look like this   print r  check list    1    gt  checked  3    gt  checked  Depending on which were checked and which were not   I m sure you can continue from this point forward

you have to name your checkboxes accordingly    lt input type  checkbox  name  check list    value         gt    you can then access all checked checkboxes with     loop over checked checkboxes foreach   POST  check list   as  checkbox          do something     ps  make sure to properly escape your output  htmlspecialchars

Edit To reflect what  Marc said in the comment below   You can do a loop through all the posted values   HTML    lt input type  checkbox  name  check list    value   lt    rowid  gt     gt   lt input type  checkbox  name  check list    value   lt    rowid  gt     gt   lt input type  checkbox  name  check list    value   lt    rowid  gt     gt    PHP   foreach   POST  check list   as  item        query to delete where item    item

Set the name in the form to check list   and you will be able to access all the checkboxes as an array   POST  check list        Here s a little sample as requested    lt form action  test php  method  post  gt       lt input type  checkbox  name  check list    value  value 1  gt       lt input type  checkbox  name  check list    value  value 2  gt       lt input type  checkbox  name  check list    value  value 3  gt       lt input type  checkbox  name  check list    value  value 4  gt       lt input type  checkbox  name  check list    value  value 5  gt       lt input type  submit    gt   lt  form gt   lt  php if  empty   POST  check list           foreach   POST  check list   as  check                echo  check    echoes the value set in the HTML form for each checked checkbox                             so  if I were to check 1  3  and 5 it would echo value 1  value 3  value 5                             in your case  it would echo whatever  row  Report ID   is equivalent to            gt

lt input type  checkbox  name  check list  lt   echo  row  Report ID     gt    value   lt   echo  row  Report ID     gt   gt    And after the post  you can loop through them      if  empty   POST  check list           foreach   POST  check list   as  report id           echo   report id was checked                   Or get a certain value posted from previous page   if isset   POST  check list    report id       echo  report id     was checked  lt br  gt
