i can`t store session value passing through jquery ajax. in codeigniter php framework -


i have problem storing session value; not able increment session count variable via ajax jquery call value passing function, set array stores session change new one.

what problem here:

1>when use 1 controller function

startonlinetest($testid=0) set session countnew 0 $this->session->set_userdata('countnew',0); , in view use jquery pass data other function of same controller public function responseonline($qid,$response)

using change effect of jquery

 echo "[removed]$(document).ready(function(){"; foreach($question['childquestion'] $q=>$aq){ // echo "\$(\"input:radio[name=qid-$q]\").live('change',function(){ var sr=\$(\"input:radio[name=qid-$q]:checked\").map(function() { return $(this).val(); }).get().join(); var qid = \$(\"input:radio[name=qid-$q]\").attr(\"qaid\"); "; echo "\$.get('"; echo base_url();echo "testpapers/responseonline/'+qid+'/'+sr,{},function(data) {\$('#res').html(data)}); });";} echo"});[removed]" ;// script working fine

now problem session value overwrite current 1 although use array code responseonline is

public function responseonline($qid,$response) { echo "this" .$this->session->userdata('countnew'); // not echo set above function startonlinetest($testid=0)[/color] set session countnew $this->session->set_userdata('countnew',0) echo $d=$qid; // know no use save time tested on $d $s=$response; if($this->session->userdata('countnew')==0) // algo function check //countnew session varaible if 0 { $sc=$this->session->userdata('countnew'); // store countnew variable echo $sc=$sc+1; // increment counter variable $this->session->set_userdata('countnew',$sc); // store in session echo "this incrementes session value"; echo $this->session->userdata('countnew'); $r2[$d]=$s; // store array value $r2 key $d , value $s $this->session->set_userdata('res',$r2); //set array value in session } else{ // if session countnew!=0 $r2=$this->session->userdata('res'); // first store $r2 array return session $r2[$d]=$s; //then add value array $this->session->set_userdata('res',$r2); // storing array session } echo '<pre>'; print_r($r2); // printing array }

i result first call fine second call value overwrite session show array([32323]=>23)) if pass function (32323,23) if pass (33,42) array([33]=>42) old value destroyed.

you should use regular sessions in php because sessions in codeigniter allow store single item. this:

$_session['item'][] = $array;

or maybe still use codeigniter sessions doing this:

$items = $this->session->userdata('items'); array_push($items, $new_item); $this->session->set_userdata('items', $items);

if want define keys well:

$items = $this->session->userdata('items'); $items['your_key'] = $new_item; $this->session->set_userdata('items', $items);

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
