PHP Buttons inside loop -

i have problem , don't know how sove it.i have inventory table contains id (that assign user)column , id_item column (that assign item items table) , items table contains id table.

more database contains: items table:

id  name  1   dagger 2   staff 3   wood shield 

each unique id.

inventory table:

id  id_item     username    name 1   3           cristi          wood shield 2   1           motoc           dagger 2   2           motoc           staff 

the id every user id , id_item item's id items table.

problem: let's i'm logged in motoc has 2 weapons in inventory. til fine. want make button every item has. buttons there not working properly. when click first 1 shows me ssss1 correct when press second 1 nothing hapens. want show me ssss2 more next $row1['id_item'].

i don't know how solve this. thank you.

this i've tried:

if (isset($_session['id'])) {     $sth1 = $dbh->prepare("select * inventory id = ".$_session['id']."");     $sth1->execute();     while($row1 = $sth1->fetch(pdo::fetch_assoc)){         $sth = $dbh->prepare("select * items id = ".$row1['id_item']."");         $sth->execute();         $row = $sth->fetch(pdo::fetch_assoc);         $ss = print $row1["id_item"]; ?>  <form id='<?php echo $row1["id_item"]; ?>' method="post" action="" >     <input type="hidden" name="refid" value="add" />     <input type="submit" name="submit<?php echo $row1["id_item"]; ?>" value="add" /> </form>  <?php     }      if (isset($_post["submit$ss"])) {         $refid = intval($_post["refid"]);         $sth1 = $dbh->prepare("select * inventory id = ".$_session['id']."");         $sth1->execute();         $row1 = $sth1->fetch(pdo::fetch_assoc);         echo "ssss".$row1['id_item'];           } } 

this bad way of building form. since you're building "personalized" form every item, there's no need create dynamic field names, hidden form field:

<form ... >     <input type="hidden" name="id_item" value="<?php echo $row1['id_item'] ?>" />     <input type="hidden" name="refid" value="add" />     <input type="submit" name="submit" value="add" /> </form> 

then check $_post['id_item'] in form handling code, instead of having every single possible submit1, submit2, etc...

as well, form handling code running within same context form generation code, before form has had chance displayed , user click. should @ least have somethign like

if ($_server['request_method'] == 'post') {     ... handle form here ...     echo "ssss..."; } 

so item info retrieval runs when form has been submitted.
