How to pass an array of checked/unchecked checkbox values to PHP email generator?

How to pass an array of checked/unchecked checkbox values to PHP email generator?

I have added a checkbox to a form that the user can dynamically add rows to. You can see the form here.

I use an array to pass the values for each row to a PHP email generator, and all works fine for other inputs, but I can't get the checkbox to work. The checkbox input currently looks like this:

Then in the PHP I have this:

$mailing = trim(stripslashes($_POST['mailing'][$i]));  

But it is not working as expected, i.e. I am only seeing 'Yes' for the first checkbox checked, and nothing for subsequent checkboxes that are checked.

One further issue is that I would like the value 'No' to be generated for unchecked checkboxes.

Could someone help with this?

Thanks,

Nick

Form:

              
                                    Full Name:                   Email:                   Telephone:                   Remove              
              
                  Add person

              
            
  

Cloning script:

$(document).ready(function() {                    $(".add").click(function() {                      var x = $("form > p:first-child").clone(true).insertBefore("form > p:last-child");                      x.find('input').each(function() { this.value = ''; });                      return false;                  });                    $(".remove").click(function() {                      $(this).parent().remove();                  });                });

$mailing = array();  foreach($_POST as $v){      $mailing[] = trim(stripslashes($v));  }  

To handle unchecked boxes it would be better to set each checkbox with a unique value:

or

Then have a list of the checkboxes:

$boxes = array(1,2,3);  $mailing = array();  $p = array_key_exists('mailing',$_POST) ? $_POST['mailing'] : array();  foreach($boxes as $v){      if(array_key_exists($v,$p)){          $mailing[$v] = trim(stripslashes($p[$v]));      }else{          $mailing[$v] = 'No';      }  }    print_r($mailing);  

You could also use this with a number of checkboxes instead:

$boxes = 3;  $mailing = array();  $p = array_key_exists('mailing',$_POST) ? $_POST['mailing'] : array();  for($v = 0; $v < $boxes; $v++){      if(array_key_exists($v,$p)){          $mailing[$v] = trim(stripslashes($p[$v]));      }else{          $mailing[$v] = 'No';      }  }    print_r($mailing);

Change the value for each checkbox to something unique:

etc. In order to do this from your jQuery code, add another line that assigns the value to the new checkbox:

x.find('input:checkbox').each(function() { this.value='Yes-'+n; });   

You'll have to define n on the initial page load. Assuming you start with only one "person", just add right above your $(".add").click handler:

var n=1;  

And then:

• in your $(".add").click handler, increment the value of n
• in your $(".remove").click handler, decrement the value of n

To get checked and unchecked both values in POST place a hidden field with exactly the same name but with opposite value as compared to the original chkbox value such that in this case the value will be '0'

            $val) {          //echo "KEY::".$key."VALue::".$val."
";          if($val == '1') { //replace '1' with the value you want to search              $found[] = $key;          }      }      foreach($found as $kev_f => $val_f) {          unset($chk_name[$val_f-1]); //unset the index of un-necessary values in array      }         final_arr = array(); //create the final array      return $final_arr = array_values($chk_name); //sort the resulting array again  }  $chkox_arr = getAllChkboxValues($_POST['chk_name']); //Chkbox Values  echo"
";  print_r($chkox_arr);  ?>

Here's my solution:
    
With an array of checkboxes in the html like so...
    
            
    
I then fix the posted array with this function...
    
$_POST[ 'something' ] = $this->fixArrayOfCheckboxes( $_POST[ 'something' ] );  function fixArrayOfCheckboxes( $checks ) {      $newChecks = array();      for( $i = 0; $i < count( $checks ); $i++ ) {          if( $checks[ $i ] == 'off' && $checks[ $i + 1 ] == 'on' ) {              $newChecks[] = 'on';              $i++;          }          else {              $newChecks[] = 'off';          }      }      return $newChecks;  }  
    
This will give me an array with values of either 'on' or 'off' for each (and every) checkbox.
    
Note that the hidden input MUST be BEFORE the checkbox input in order for the function to work right.
