zen_draw_form() - doesn't do anything?

[nazca]

I tried hard coding a form into my website but I was greeted with a 404 error. A google search led me to the knowledge that I wasn't passing a security token and I needed to use zen_draw_form()

I am using zen_draw_form to create an add to cart button for a custom "pack" of items on our site. Searching for zen_draw_form syntax has taken a while. I finally found to look in html_output.php for the syntax and did.

I have tried:

zen_draw_form(); 
//hoping for at least a default button? - nothing

zen_draw_form('cart_quantity', 'index.php?main_page=product_info&cPath=24&products_id=876&action=add_product', 'post');
//nothing again.

zen_draw_form('cart_quantity', 'index.php?main_page=product_info&cPath=24&products_id=876&action=add_product', 'post', 'products_id="876"');
//nothing again!

zen_draw_form('warranty', zen_href_link(FILENAME_WARRANTY, '', 'NONSSL'), 'post');
//from zen cart essentials.  Displays nothing.

What am I doing wrong? What do I need to do? I need the products id to be variable as well. so it needs to be something like...

$products_id = 1 ;
zen_draw_form('cart_quantity', 'index.php?main_page=product_info&cPath=24&products_id=' . $products_id . '&action=add_product', 'post');

But of course, that doesn't work either.

You need to echo the output of the function, e.g.

echo zen_draw_form('warranty', zen_href_link(FILENAME_WARRANTY, '', 'NONSSL'), 'post');

Thank you very much lat9. I swear I was typing post #3 before I saw yours =P

No problem; I figured, based on the timestamps, that that's what happened!

GOT IT! That only took a couple of hours =\

the trick is to echo it =P

Here is how I solved my problem with zen_draw_form or zen_draw_form() not displaying anything or not working. You need to echo it. It doesn't echo by itself.

Here is the code I ended up using.

<?php
    $products_id = $_POST['products_id'];
    echo zen_draw_form('cart_quantity', zen_href_link(zen_get_info_page($products_id), zen_get_all_get_params(array('action')) . 'action=add_product', $request_type), 'post', 'enctype="multipart/form-data"');
?>
<input type="hidden" name="cart_quantity" value="1" maxlength="6" size="4" />
<input type="hidden" name="products_id" value="<?php echo $products_id ; ?>" />
<input type="image" name="image" title=" Add to Cart " src="/includes/templates/CUSTOM_TEMPLATE/buttons/english/button_in_cart.gif" alt="Add to Cart " />
</form>

I'm still a little confused about the values actually needed in the function. But they are effectively overwritten in the following hidden fields it looks like. I've tested it and it's working as intended.

zen_draw_form only draws the opening form tag. Not the rest of the form for you. You need to add submit buttons and some hidden fields if you need to and close the form with </form>.

Any extra input would be nice!



P.S. My code has some more security measures than that dispalyed here so dont worry =P
