Order Comments

[Andy_GS]

Hi guys, i'm trying to put a javascript thing together to prevent people from entering more than 70 characters into the 'order comments' text box.

i placed this code (includes/modules/pages/checkout/jscript_main.php):

function countAreaChars(areaName,counter,limit)
{
if (areaName.value.length>limit)
areaName.value=areaName.value.substring(0,limit);
else
counter.value = limit - areaName.value.length;
}

<?php echo zen_draw_textarea_field('comments', '20', '3', '', 'onKeyDown="countAreaChars(this.form.feedback,this.form.leftChars,70);" onKeyUp="countAreaChars(this.form.feedback,this.form.leftChars,70);"'); ?>

however the javascript doesn't seem to be pulling in. Have i declared it in the wrong file?

regards
Andy.

You could look at what's done for the Text-Attribute-Type on the product_info page, for inspiration on a way that works.

Hi Doc,

i've looked at this page and, i think you're refering to (line 156):

    $the_button = PRODUCTS_ORDER_QTY_TEXT . '<input type="text" name="cart_quantity" value="' . (zen_get_buy_now_qty($_GET['products_id'])) . '" maxlength="6" size="4" /><br />' . zen_get_products_quantity_min_units_display((int)$_GET['products_id']) . '<br />' . zen_draw_hidden_field('products_id', (int)$_GET['products_id']) . zen_image_submit('cart.jpg', BUTTON_IN_CART_ALT); 

however the max length attribute is not a valid textarea attribute. I think i'm just looking for help on where to deploy the javacript, as it didn't seem to work in the checkout js header.

or have i missed understood?

regards
Andy.

You've misunderstood my point.

Add a textarea attribute (ie: a text attribute with the "number of lines" set to more than 1) to a sample product.
Then visit that product's page in your store.
You'll see the counter/restriction in effect.
Then you can peek a the HTML and javascript for the inspiration you need.
