The PHP way of doing this would be using a dialog system inside php.for example GTKDialogs: http://www.kksou.com/php-gtk2/articles/setup-a-dialog-box---Part-2---simple-yes-no-dialog.php The javacript way is probably a bit easier, but remember when javascript is turned off, this does not work (except if you check javascript to be enabled and then add this!?) This could be with a onclick handler like tsvanharen posted, or with a simple text dialog inside the page instead of a nagging popup.

<a onClick="$('deletefromtable').show();"></a>
<div id="deletefromtable" style="display:none;">
 Do you really want to do this?<br/>
 <a href="deleteit.php">Yes</a>|<a onClick="$('deletefromtable').hide();">No</a>
</div>

I use prototype (hence the $() tag and the show()/hide()) for it. but you can easily change it to work without prototype:

<a onClick='document.getElementById("deletefromtable").style.display = "block";' href="#">click here to delete</a>
<div id="deletefromtable" style="display:none;">
 Do you really want to do this?<br/>
 <a href="deleteit.php">Yes</a>|<a onClick='document.getElementById("deletefromtable").style.display = "none";' href="#">No</a>
</div>

Again, this does not work without javascript, but almost no options do.

You can handle the attribute onClick for both i e   ok   amp   cancel  condition like ternary operator Scenario  Here is the scenario that I wants to show confirm box which will ask for  ok  or  cancel  while performing a delete action  In that I want if user click on  ok  then the form action will redirect to page location and on cancel page will not respond  Adding further explanation i m having one button with type  quot submit quot  which is originally use default form action of form tag  and I want above scenario on delete button with same input type  So below code is working properly for me onClick  quot return confirm  Are you sure you want to Delete     this form action   lt  php echo   SERVER  PHP SELF     gt   false  quot   Full code  lt input type  quot submit quot  name  quot action quot  id  quot Delete quot  value  quot Delete quot  onClick  quot return confirm  Are you sure you want to Delete     this form action   lt  php echo   SERVER  PHP SELF     gt   false  quot  gt   And by the way I m implementing this code as inline in html element using PHP  so that s why I used  echo   SERVER  PHP SELF     I hope it will work for you also  Thank You

If you re deleting something  you should always use POST and not GET  so using confirm   is a bad idea   What I do in your situation is use a modal popup like jqModal and display a form with yes no buttons inside the popup

You can use JavaScript to prompt you   Found this here - Example   lt script gt  function confirmDelete delUrl      if  confirm  Are you sure you want to delete         document location   delUrl         lt  script gt    lt a href  javascript confirmDelete  delete page id 1    gt Delete lt  a gt    Another way   lt a href  delete page id 1  onclick  return confirm  Are you sure you want to delete     gt Delete lt  a gt     Warning  This JavaScript will not stop the records from being deleted if they just navigate to the final url - delete page id 1 in their browser

I was also looking for a way to do it and figured it out like this using forms and the formaction attribute    lt input type  submit  name  del something  formaction   lt addresstothispage gt   value  delete    gt   lt  php if isset   POST  del something     print   lt div gt Are you sure   lt input type  submit  name  del confirm  value  yes   formaction  action php    gt   lt input type  submit  name  del no  value  no   formaction   lt addresstothispage gt     gt     gt    action php would check for isset   POST  del confirm    and call the corresponding php script  for database actions or whatever   Voil    no javascript needed  Using the formaction attribute  the delete button can be part of any form and still call a different form action  such as refer back to the same page  but with the button set    If the button was pressed  the confirm buttons will show

What I usually do is create a delete page that shows a confirmation form if the request method is  GET  and deletes the data if the method was  POST  and the user chose the  Yes  option   Then  in the page with the delete link  I add an onclick function  or just use the jQuery confirm plugin  that uses AJAX to post to the link  bypassing the confirmation page   Here s the idea in pseudo code   delete php    lt  php if    SERVER  REQUEST METHOD       POST         if    POST  confirm       Yes             delete record   REQUEST  id        From GET or POST variables           redirect   POST  referer         gt    lt form action  delete php  method  post  gt      Are you sure       lt input type  submit  name  confirm  value  Yes  gt       lt input type  submit  name  confirm  value  No  gt        lt input type  hidden  name  id  value   lt  php echo   GET  id      gt   gt       lt input type  hidden  name  referer  value   lt  php echo   SERVER  HTTP REFERER      gt   gt   lt  form gt    Page with delete link    lt script gt      function confirmDelete link            if  confirm  Are you sure                   doAjax link href   POST       doAjax needs to send the  confirm  field                   return false         lt  script gt    lt a href  delete php id 1234  onclick  return confirmDelete this    gt Delete record lt  a gt

onclick  return confirm  Log Out     window open   user logout    self    void 0      Did this script and afterwards i tought i go check the internet too  Yes this is an old threat but as there seems not to be any similar version i thought i d contribute  Easiest  amp  simplest way works on all browsers with in any element or field   You can change window open to any other command to run when confirmation is TRUE  same with void 0  if conformation is NULL or canceled
