Shopping cart page - unable to update product quantity

[frank18]

This one got me puzzled (client site): When on the shopping cart page, I am unable to update the quantity in cart of any given product. I can change the quantity in the box but pressing the update icon does nothing.

Site is bubs2grubsknitting[dot]com[dot]au
ZC version 1.5.5e
PHP 5.6.30

I have scoured through virtually every similar thread dealing with this issue, to no avail.

Compared the files

includes/modules/pages/shopping_cart/header_php.php
includes/templates/bubs/template/tpl_shopping_cart_default.php

to relevant stock files and can't find any differences (other than css / display changes in the override template file).

Thanks guys

looks like your form is closing before the quantity input field and update button. should be below input or just above the shipping estimator section.

Thanks Dave, but that is not the case. Form closes just above the shipping estimator section, exactly the same as it is in the stock template_default/templates/tpl_shopping_cart_default.php file - no difference.

If you're questioning the files (though there are many others that support even what is seen in the code above and there are database settings to boot), then upon submission of the form, the general process would include:
includes/auto_loaders/config.base.php which loads
includes/init_includes/init_cart_handler.php which loads
includes/main_cart_actions.php which is expected to load
All of the includes/extra_cart_actions files which may prevent "update" or change of the total amount/quantity before feeding back to have the shopping_cart page load again. After those files (if present) are parsed/acted upon then there is the shopping_cart class itself found in includes/classes. Then through all this there is the possibility of one or more observers that could be taking action to prevent changing the total quantity in the cart. There also could be a cart override "class" that is loaded ahead of the default shopping_cart class to take its place and that may have something involved.

Lots of possibilities. Would suggest identifying what has been installed that might have modified any of those files or that process, differences in the overall system, and anything else that might be further helpful.

Site is bubs2grubsknitting[dot]com[dot]au

It is a JavaScript problem. If JS is disabled the quantity can updated.

Further checking showed you are loading jQuery twice, and two different versions.

Results of viewing page source shows:

#25

<script type="text/javascript">window.jQuery || document.write(unescape('%3Cscript type="text/javascript" src="//code.jquery.com/jquery-1.12.0.min.js"%3E%3C/script%3E'));</script>

#153 - #157

<link rel="stylesheet" type="text/css" href="includes/templates/bubs/css/zen_lightbox.css"><script type="text/javascript">
        if (typeof jQuery == 'undefined') {  
  document.write("<scr" + "ipt type=\"text/javascript\" src=\"//code.jquery.com/jquery-1.11.3.min.js\"></scr" + "ipt>");
  }
</script>

Lines #153 - #157 should be removed as 'zen_lightbox.css' was previously loaded as was 'jquery-1.12.0.min.js'.

Even better is to not use Slimbox but some other script.

[mc12345678]

Zen Colorbox is about to be updated, just verifying the installation script and then will be submitting as an update to: https://www.zen-cart.com/downloads.php?do=file&id=1322

Current version includes documentation to support manually applying the SQL; however, the version currently on the site needs massaging (expecting to upload it, but didn't yesterday). The issues with the sql are that some do not identify the fields to which the value is to be applied so in some queries if the associated table had been modified there might be an error/issue, also that NULL is used to assign to the configuration_id that auto-numbers and that could be an issue depending on the system/database to which it is applied (some expect '' instead of NULL). Anyways, that software is available at https://github.com/mc12345678/zen-co...ree/z4a-master.

There is currently an auto-install script provided. It can be used or ignored. To remove it or not use it, simply remove (prior to navigating the admin after upload of the files) or do not upload the file admin/includes/auto_loaders/config.zcb.php

None of the files listed above have been altered or are missing, all are standard ZC 1.5.5e files.

Had that inkling, need to look into this further.

Lines #153 - #157 should be removed as 'zen_lightbox.css' was previously loaded as was 'jquery-1.12.0.min.js'.....

Did that, no change...

[Website Rob]

Two things I noticed.

You mentioned using 1.5.5e but it looks like some links are hard-coded, old code? Reason being is I see 'main_page=page&id' instead of 'main_page=page&id' in a lot of links.

		<ul>
		<li><a href="index.php?main_page=page&id=13">Shipping</a></li>
		<li><a href="index.php?main_page=page&id=6">Ordering</a></li>
		<li><a href="index.php?main_page=page&id=4">Payment</a></li>
		<li><a href="index.php?main_page=page&id=10">Returns Policy</a></li>
		<li><a href="index.php?main_page=page&id=26">Q &amp; A</a></li>
		<li><a href="index.php?main_page=page&id=9">Privacy Policy</a></li>
		</ul></li>

The other is when editing was done to the Shopping page there was an incorrect placement of HTML code.

Edit should be like so:

<form name="cart_quantity" action="https://bubs2grubsknitting.com.au/index.php?main_page=shopping_cart&amp;action=update_product&amp;zenid=removed_by_WR" method="post" id="shoppingCartForm"><input type="hidden" name="securityToken" value="removed_by_WR" />

<div>
<p style="text-align: center;">
<strong style="font-family: Verdana; color: rgb(255, 0, 0);">If ordering discontinued product please do not order more than current stock holding as these are also unavailable at the suppliers.</strong></p>
<p style="text-align: center;">
<br />
<span style="color:#800080;"><span style="font-size: 12px;"><span style="font-family: Verdana;"><strong>If your order is over $100 and contains mainly discontinued yarns payment of postage would be much appreciated as these are priced out at cost + 10% GST.</strong></span></span></span></p>
<p style="text-align: center;">
<span style="color:#0000ff;"><span style="font-size: 12px;"><span style="font-family: Verdana;"><strong>$10 Flate rate - if you order fits in a 3kg satchel it will be posted via express post</strong></span></span></span><br />
&nbsp;</p>
</div>

As it is currently, a <div> tag is missing and the FORM is not properly coded. This may or may not solve the Quantity problem but it is coding that needs to be corrected.

Speaking of which, I found the above problems using the validator.w3.org which is always a handy tool--regardless of having problems or not.
