How to Add "onsubmit" in Product_info.php

[daipayan]

Hello,

 

I am new to PHP as well as Oscommerce.

 

I have the following problem in product_info.php

 

Here I want to validate the product attribute selection before submitting to Shopping Cart.

 

I had inserted the validation in template_top.php i.e.

 

<script language="javascript"><!--
function validate(cart_quantity) {
<?php
$products_options_name_query = tep_db_query("select distinct popt.products_options_id, popt.products_options_name from " . TABLE_PRODUCTS_OPTIONS . " popt, " . TABLE_PRODUCTS_ATTRIBUTES . " patrib where patrib.products_id='" . (int)$HTTP_GET_VARS['products_id'] . "' and patrib.options_id = popt.products_options_id and popt.language_id = '" . (int)$languages_id . "' order by popt.products_options_name");
 while ($products_options_name = tep_db_fetch_array($products_options_name_query)) {
?>
if (cart_quantity.elements['id[<?php echo (int)$products_options_name['products_options_id']; ?>]'].value == -999) {
 alert('Sie müssen die Optionen für Ihr Produkt wählen: <?php echo $products_options_name['products_options_name']; ?>');
 cart_quantity.elements['id[<?php echo (int)$products_options_name['products_options_id']; ?>]'].focus();
 return false;
}
<?php
}
?>
}
//--></script>

 

Now, to validate this above code, I need to insert

'onsubmit="return validate(this);"'

in

echo tep_draw_form('cart_quantity', tep_href_link(FILENAME_PRODUCT_INFO, tep_get_all_get_params(array('action')) . 'action=add_product'));

of product_info.php page, but failed to do that.

 

Please help me.

Hope to hear from you all soon.

 

Regards,

Daipayan

<?php
require('includes/application_top.php');
?>

<script>
function validate(){
alert("Daipayan's javascript");
}
</script>

<?php
echo tep_draw_form('cart_quantity', tep_href_link(FILENAME_PRODUCT_INFO, tep_get_all_get_params(array('action')) . 'action=add_product'), 'post', 'onsubmit="validate()"');
?>
<button>Submit</button>
</form>

 

works all right for me from my

 

public_html/catalog

 

though it doesn't return anything, just displays an alert.

Hello there,

 

I am using version 2.3 where I am unable to input the code as you said so, need something to insert the small piece of code by somehow!

 

I want to display the alert only, need nothing else.

There is. most likely, an addon that already does this so you should check that before reinventing the wheel. For example, if you want to make it so your customers have to pick an attribute, there is the must select addon. Or if you are concerned about the quantity available of the attributes, there is the QTPro addon.
