php code

<?php     session_start();      $connect = mysql_connect("localhost", "root", "") or die ('{"opp":"error","box":"mysql_connect failed"}');      $db = mysql_select_db("sample");       // test vars jquery form     $status = mysql_real_escape_string($_request['status']);     $company = mysql_real_escape_string($_request['company']);     $requested = mysql_real_escape_string($_request['requested']);     $activity = mysql_real_escape_string($_request['activity']);     $address = mysql_real_escape_string($_request['address1']);     $service = mysql_real_escape_string($_request['service']);     $destroydate = mysql_real_escape_string($_post['datepicker']);     $date = explode('/', $_post['datepicker']);     $newdate = $date[2].'-'.$date[1].'-'.$date[0];     //$box = mysql_real_escape_string($_request['box_add']); // never used     $authorised = mysql_real_escape_string($_session['kt_name_usr']);     $dept = mysql_real_escape_string($_request['dept']);     $boxerrortext = 'error';      // split box if multiples     $array = explode(',', $_request['box_add']);      $outstring = '';       foreach ($array $box) {         $box = mysql_real_escape_string($box);         $sql = "select item act item = '$box'";         $result = mysql_query($sql) or die ('{"opp":"error","box":"' . mysql_error() . '"}');          // if there dupe entries, send message jquery         if (mysql_num_rows($result) > 0) {              $outstring .= $box . ' ';            }        }     if ($outstring) {         $error = array('opp' => "error", 'box' => $outstring);           $output = json_encode($error);         echo $output;         exit();     }      foreach ($array $box) {         $outstring .= "<br />company:  $company <br /> address: $address <br />service: $service <br />destroy date: $destroydate <br />box: $box <br />";          $box = mysql_real_escape_string($box);         $sql = "insert `temp` (service, activity, department, company, address, user, destroydate, date, item, new)";         $sql .= "values ('$service', '$activity', '$dept', '$company', '$address', '$requested', '$newdate', now(), '$box', 1)";         $result = mysql_query($sql) or die ('{"opp":"error","box":"' . mysql_error() . '"}');     }      $json = array('opp' => 'insert', 'box' => $outstring);     $result = json_encode($json);     echo $result; ?> 

script add inputs

<script type="text/javascript"> $(function() {  var maxinputs       = 8; //maximum input boxes allowed var inputswrapper   = $("#intkinputswrapper"); //input boxes wrapper id var addbutton       = $("#intkaddmorefilebox"); //add button id  var x = inputswrapper.length; //initlal text box count var fieldcount=1; //to keep track of text box added  $(addbutton).click(function (e)  //on add input button click {         if(x <= maxinputs) //max input box allowed         {             fieldcount++; //text box added increment             //add input box             $(inputswrapper).append('<div><input type="text" name="box_add" id="box_add" /><a href="#" class="removeclass">&times;</a></div>');             x++; //text box increment         } return false; });  $("body").on("click",".removeclass", function(e){ //user click on remove text         if( x > 1 ) {                 $(this).parent('div').remove(); //remove text box                 x--; //decrement textbox         } return false; })   }); </script> 

why don't enumerate inputs instead?

something like:

    $(inputswrapper).append('<div><input type="text" name="box_add'+fieldcount+'" id="box_add'+fieldcount+'" /><a href="#" class="removeclass">&times;</a></div>'); 

and when removing input add rest counter

fieldcounter--; 

now, on php side, can process these fields by:

• using regex find max amount of inputs sent based on input id (if box_add7 exists, 7 max number of box_add iterate)

• or send field counter value on hidden field

• or, if using ajax, parameter value of fieldcount.

  for ($i = 1; $i <= fieldcounter; $i++){   $value = $_post["box_add".$i];   //do $value }
