php - Javascript function not being called from onchange (not always) -


at moment, i'm in process of creating website, have products have quantity. quantity depends on size , color.

so came following procedure check , give feedback how many there still left.

<div class="product_stock" id="stock_form<?php echo $i; ?>"><?php    $size = $product_sizes[0];   $color = $product_colors[0];   $sql = "select * products product_id = '$product_id' , size = '$size' , color = '$color'";   $result = mysql_query($sql) or die(mysql_error());     echo $sql;    if(mysql_num_rows($result) > 0) {     $product_stock = mysql_fetch_array($result);     if($product_stock['stock'] > 0) {       echo "nog ".$product_stock['stock']." verkrijgbaar";     } else {       echo "combinatie niet meer verkrijgbaar";     }    }?> </div> <div class="product_text">    <?php echo $product['text']; ?>        </div> <div class="product_num">   art: #<?php echo $product['product_id']; ?> </div> <div class="product_bar_bot">   <form name="form<?php echo $i; ?>" action="shopping_cart.php?">     <input type="hidden" name="id" value="<?php echo $product['pid']; ?>"/>       <select name="size" class="product_select" onchange="get_stock('form<?php echo $i; ?>');">     <?php foreach($product_sizes $p_size) { ?>     <option>       <?php echo $p_size; ?>     </option>   <?php } ?> </select> <select name="color" class="product_select" onchange="get_stock('form<?php echo $i; ?>');">    <?php foreach($product_colors $p_color) { ?>     <option value="<?php echo $p_color; ?>">       <?php echo $color_array[$p_color]; ?>     </option>   <?php } ?> </select> <input type="hidden" name="url" value="sale"> <input type="hidden" name="action" value="add"> <input type="text" name="amount" value="1" size="1" style="vertical-align: top; margin-top: 9px;"></input> <img src="images/icons/cart_shop.png" align="top"/>  <input type="submit" class="button" value="voeg toe" style="vertical-align: top; margin-top: 7px;">

the function required called:

function get_stock(formid) {   var form = document.forms[formid];   var size = form.size.value;   var color = form.color.value;   var pid = form.id.value;   var stock = 'stock_'+formid;    // code ie7+, firefox, chrome, opera, safari   if (window.xmlhttprequest)  {     xmlhttp=new xmlhttprequest();   } else {     // code ie6, ie5     xmlhttp=new activexobject("microsoft.xmlhttp");   }   xmlhttp.onreadystatechange=function() {     if (xmlhttp.readystate==4 && xmlhttp.status==200) {       document.getelementbyid(stock).innerhtml=xmlhttp.responsetext;     }   }   xmlhttp.open("get","get_stock.php?id="+pid+"&size="+size+"&color="+color,true);   xmlhttp.send(); }

the problem i'm having work of forms, forms get_stock.php page isn't being called.

if more information needed don't hesitate ask.

i made small error fixed, @bergi's comment. creating forms adding +1 @ $i each time, reseted $i @ wrong place, resulted in more 1 of $i = 1 example.
