Not able to increment in foreach loop to get the values of an array

Recommended Posts

hi, i’m currently facing a new problem (i managed to use array_unique function successfully but i face this problem)with my php loop. i couldn’t seem to increment in my foreach loop to get the value of an array.
here is my code:

$update_id1=Array ( [0] => 398 [1] => 397 [2] => 393 [3] => 391 [8] => );

//$i=0;
foreach ($update_id1 as $i => $v) {

     $ex= explode(",", $v);
     $unique=array_unique($ex);

//f$ketch username from update table in db and inject it to the feed query.
   $imp_id= implode(',', $ids);
//$id1=$ids[$i];
  // $x=0;
 // for($x=0;$x<count(unique);$x++){ 
   echo 'ids:- '.$i; print_r($unique[$i]); echo '<br>';
   
//}
   

            
$totalUpdates=$project->totalUpdates($ids[$i],$_SESSION['uname'] ,$unique[$i],$load);   

 //$i++;
 }

i tried every method nothing seems to work can anyone help me in this regard please.

Why don't you post your actual code (that code won't execute past the first line) and tell us what you are trying to achieve, not just how you are failing to do whatever it is.

here is the total updates class function:

 

Quote

public function totalUpdates($friend,$session,$var_id, $load) {
    try{
   // $sql2="SELECT distinct update_id,update_body,time,title,user_id_u,account_name,author,data FROM updates WHERE author=:friend and account_name=:session order by time desc limit $load,2";
   $sql2="SELECT distinct update_id,update_body,time,title,user_id_u,account_name,author,data FROM updates where author in (:friend,:session) and update_id >:update_id_all  order by time desc limit $load,2";
        $stmth=  $this->_db->prepare($sql2);//Check here syntax of $db 
    $stmth->bindValue(":session",$session);
    $stmth->bindValue(":friend",$friend);
    $stmth->bindValue(":update_id_all",$var_id);
    //$stmth->bindValue(":update_id2",$update_id2);
    $stmth->execute();
    return $stmth->fetchAll();
    } catch (PDOException $ei){
        echo $ei->getMessage();
    }
}

here is the full code:

  $f = array();
  $ids=  array();
$stmt=  $conn->prepare("select friend_one, friend_two from friends where (friend_one=:session OR friend_two=:session) and (friend_one>=:session or friend_two>=:session) and accepted='1'");
$stmt->bindparam(":session",$_SESSION['uname']);
$stmt->execute();
$f=$stmt->fetchAll();
$f_count=count($f);

$ids=  ff($f, $project);
//$k=0;
//for ($k=0;$k<count($ids);$k++){
 //while($i<$f_count){    
//$id=$v;
//$i=0;
foreach ($update_id1 as $i => $v) {

     $ex= explode(",", $v);
     $unique=array_unique($ex);

//f$ketch username from update table in db and inject it to the feed query.
   $imp_id= implode(',', $ids);
//$id1=$ids[$i];
  // $x=0;
 // for($x=0;$x<count(unique);$x++){ 
   echo 'ids:- '.$x; print_r($unique[$x]); echo '<br>';

@Barand i'm trying to pass on the array values from unique and ids in to the totalUpdates class the problem is i'm using the foreach loop's incrementing feature $i to feed values from update_id and ids array and the incrementing feature is not working as the ajax is not fetching values after 2 posts. i'm sorry for using quote feature as code feature was not available

@Barand the $i feature passed in foreach loop. if that's not an incrementing feature then what should i do to increment the variables value as using loops repeatedly creates ajax to produce duplicate values. i'mm also post the ajax here for you to inspect.

in the code 

foreach ($array as $i => $v)
  • $i = index of the current element
  • $v = value of the current element

You use a function ff() as in

$ids=  ff($f, $project);

but I can't see it defined anywhere. What does it do? Then I'll have some idea of what the data in $ids looks like.

here is the function @Barand

function ff(&$s, $project) {

 $verify_friend=array();
foreach ($s as $i=> $r ){
    
  $r["friend_one"] == $_SESSION['uname'] ? $friends[]= $r["friend_two"] : $friends[] = $r["friend_one"]; 
//$r["friend_two"] == $_SESSION['uname'] ? $friends[]= $r["friend_one"] : $friends[] = $r["friend_two"]; 


  $verify_friend= $project->totalids($_SESSION['uname'],$friends[$i]);  
 /*_4_session",function(e){

  var_dump($totalids);

   array_push($output, $friends);
   

   
}
   
return $friends;
}

OK, so ff() returns an array of the user's friend ids.

The next uncommented line is


foreach ($update_id1 as $i => $v) { 

What does $update__id1 contain (there doesn't appear to be a prior reference)?

@Barand it contains json value passed from jquery got through DOM check the javascript for details and here is the update_id variable decoding the array:

Quote

$update_id1= json_decode(stripslashes($_POST['update_id1']));

$load=  (int)($_POST['load']);
$sess_count=(int)($_POST['sess_count']);

As I obviously cannot run the script to see for myself, perhaps you would be kind enough to give me an example of the data being passed.

My main concern is the structure of your code. You are running a query to get an array of ids and then looping through that resulting array to run queries based on those ids.

Running queries within loops is extremely inefficient. You should be running a single query which joins the tables on those ids to get the data you require.

@Barandi'm not a mysql or a javascript guy i can't imagine how to write efficient queries.i have asked too much of you it seems. i'll post the data being passed here its html i get the first two posts from mysql table but after that it isn't showing anything i suspect that the $friend variable and $unique variable is not working properly, firebug in chrome doesnt show any errors just wait for the html data being produced by the ajax and query.

 

here is the output from the page:

As @Barand has stated, without knowing what $update_id1 contains and it's exact structure, it is impossible to know what the problem is, but I have a couple of comments

1. Your original post contained this

$update_id1=Array ( [0] => 398 [1] => 397 [2] => 393 [3] => 391 [8] => );

//$i=0;
foreach ($update_id1 as $i => $v) {

    $ex= explode(",", $v);
    $unique=array_unique($ex);

    //f$ketch username from update table in db and inject it to the feed query.
    $imp_id= implode(',', $ids);
    //$id1=$ids[$i];
    // $x=0;
    // for($x=0;$x<count(unique);$x++){ 
    echo 'ids:- '.$i; print_r($unique[$i]); echo '<br>';
}

Assuming there was a "real" array defined, within the foreach() loop the code first does an explode on the value - even though your example values have no commas for the explode. Then you store the unique values in a new variable called $unique. Then you do an implode of an array called $ids - which has never been defined. I think you meant to do an implode of the unique values ???

2. While this line may work

$r["friend_one"] == $_SESSION['uname'] ? $friends[]= $r["friend_two"] : $friends[] = $r["friend_one"];

 . . . it is an awkward implementation. This is much more precise and readable.

$friends[] = ($r["friend_one"] == $_SESSION['uname']) ? $r["friend_two"] : $r["friend_one"];

But, I'm betting there is a better way to determine the value within your query.

@Barand i found out what the problem was update_id1 had an array like this array ([0]=>398,399,405,407) so it was not incrementing hence the problem. 

but now i face a new problem that is based on the same scripts above you can check it in this link if you think you can spare some time in your busy schedule pl check it out.
