problem with putting in URL

[swissbeets]

I am trying to save the shirt size and then bring it back up in the shopping cart page, but i cannot get it to come up in the URL

 

this is the function that displays the drop down menu,  the array is ('S','M','L','XL')  i cannot figure out what variable to use or how to use it

 

function showOptionsDrop($array, $active, $echo=true){

        $string = '';

 

        foreach($array as $k => $v){

            $s = ($active == $k)? ' selected="selected"' : '';

            $string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n";   

        }

 

        if($echo)  echo $string;

        else        return $string;

    }

 

 

this is my hyperlink to save this information

 

 

cho "<a href=\"shoppingcart.php?prod=".urlencode($row['product_id'])."?&size=$string[$k]"."?&action=add\">Add to Shopping Cart"."</a>";

 

 

i will then make a GET and display the size in the shopping cart but my URL will not work

 

do i have to do something witth the session?  any help is greatly appreciated

You have to get the value of the dropdown via javascript if you want to do it this way.

 

You are better off just wrapping each "item" in a form. Make a hidden input field with the name prod and the value of $row['product_id'], you already have the select menu for size, and then just add another hidden input with name action and value of add.

 

Make sense?

kind of i do not know how to use a hidden field but can find out

 

but as for the rest, product id, and action are already being passed to the next page,

 

i have up to this far working but then realized i needed to put sizes in there 

 

any chance you could clarify please i am still very new but want to learn

All the other values work fine because the values are already known while PHP is building the page. The size though, is not. JavaScript is messy and, if someone has it disabled, they can't buy something from your site....

 

Instead, do something like this:

<?php
while($row=mysql_fetch_assoc($result)){
?>
<form method="GET" action="shoppingcart.php">
  <input type="hidden" name="prod" value="<?php echo urlencode($row['product_id']); ?>" />
  <input type="hidden" name="action" value="add" />
<?php showOptionsDrop($array,'M'); ?>
  <input type="submit" value="Add to Shopping Cart" />
</form>
<?php
  }
?>

does this go inside my first while loop? sorry i am very new to this ?

 

this is my current while loop

 

while($row = mysql_fetch_array($product_set)){

 

 

 

    echo "<p>";

    echo $row['product_name']."<br />";

    echo "$".$row['product_price']."<br />"."<br />";

    show_picture($row); 

echo "<br/>";

 

 

echo  "Size: ";  ?><p>

<select name="size">

<?php

$size = array('Select','S','M','L','XL');

showOptionsDrop($size);

?>

</select>

</p> <?php

               

 

echo "<a href=\"shoppingcart.php?prod=".urlencode($row['product_id'])."?&size=['$size']"."?&action=add\">Add to Shopping Cart"."</a>";

} 

 

 

your saying i should make it a form with hidden values rather than even use a session? 

[rhodesa]

nothing in your code here has anything to do with sessions...but what i'm saying, is the above code should be changed to:

 

<?php
while($row = mysql_fetch_array($product_set)){
?>
<form method="GET" action="shoppingcart.php">
  <input type="hidden" name="prod" value="<?php echo $row['product_id']; ?>" />
  <input type="hidden" name="action" value="add" />
  <p>
    <?php echo $row['product_name']; ?><br />
    $<?php echo $row['product_price']; ?><br /><br />
    <?php show_picture($row); ?><br />
    Size: 
    <p>
      <select name="size">
        <?php showOptions(array('Select','S','M','L','XL')); ?>
      </select>
    </p>
    <input type="submit" value="Add to Shopping Cart" />
  </p>
</form>
<?php
}  
?>

ok i understand what your saying with this and did so, but  it is only displaying the top product and and not displaying a submit button        these variables will be POSTed and then i can easily GET them at a later date is this correct?
