I have a custom shipping estimation block on the checkout cart page to calculate the shipping rate. It's working well until there are many products (5 or more) on the cart. I add the product one by one to the cart. Somehow the shipping estimation block is gone if the products counter on the cart reach 5 (sometimes 6). If I remove the new added product, the shipping estimation block is back. I found no error about it. I do it for different products and the same issue happened. It make me puzzle. Why this is happened? How to trace the origin problem?
Magento_Checkout/templates/cart/shipping.phtml:
<div id="block-summary" data-bind="scope:'block-summary'" class="content" data-role="content" aria-labelledby="block-shipping-heading">
<!-- ko template: getTemplate() --><!-- /ko -->
<script type="text/x-magento-init">
{
"#block-summary": {
"Magento_Ui/js/core/app": <?php /* @escapeNotVerified */ echo $block->getJsLayout();?>
}
}
</script>
<script>
window.checkoutConfig = <?php /* @escapeNotVerified */ echo \Zend_Json::encode($block->getCheckoutConfig()); ?>;
window.customerData = window.checkoutConfig.customerData;
window.isCustomerLoggedIn = window.checkoutConfig.isCustomerLoggedIn;
require([
'mage/url',
'Magento_Ui/js/block-loader'
], function(url, blockLoader) {
blockLoader("<?php /* @escapeNotVerified */ echo $block->getViewFileUrl('images/loader-1.gif'); ?>");
return url.setBaseUrl('<?php /* @escapeNotVerified */ echo $block->getBaseUrl();?>');
})
</script>
Anybody know how to trace it? The shipping estimation block is not disabled or hidden. I got $block->getJsLayout() give same result no matter the shipping estimation block is displayed or not. Somehow the template shipping-estimation.html is not rendered (This form with id='shipping-zip-form' ... not rendered). it should render like this:
...
<!-- START_MSPDEV[bfdd122979ad7f283290bc9e5e1fa7b7]: checkout.cart.shipping -->
...
<div id="block-summary" data-bind="scope:'block-summary'" class="content" data-role="content" aria-labelledby="block-shipping-heading">
<!-- ko template: getTemplate() -->
<!-- ko foreach: {data: elems, as: 'element'} -->
<!-- ko if: hasTemplate() -->
<!-- ko template: getTemplate() -->
<form method="post" id="shipping-zip-form" name="shipping-zip-form" data-bind="afterRender: loadForm"> <---FROM shipping-estimation.html
<div class="fon-ship-method">
<h4>SELECT DELIVERY METHOD FOR ORDER</h4>
...
</div>
</form>
<!-- /ko -->
<!-- /ko -->
<!-- ko if: hasTemplate() -->
<!-- ko template: getTemplate() -->
<form id="co-shipping-method-form" data-bind="blockLoader: isLoading, visible: isVisible()" class=""> <---FROM shipping-rates.html
<p class="field note" data-bind="visible: (shippingRates().length <= 0)">
<!-- ko text: $t('Sorry, no quotes are available for this order at this time')-->Sorry, no quotes are available for this order at this time<!-- /ko -->
</p>
<fieldset class="fieldset rate" data-bind="visible: (shippingRates().length > 0)" style="display: none;">
<dl class="items methods" data-bind="foreach: shippingRateGroups"></dl>
</fieldset>
</form>
<!-- /ko -->
<!-- /ko -->
<!-- /ko -->
<!-- /ko -->
...
</div>
...
I traced until the core file in Magento_Ui/js/lib/core/element/element.js:
...
getTemplate: function () {
if(this.template.indexOf("Magento_Checkout/cart/") > -1){
debugger;
}
return this.template;
},
...
hasTemplate: function () {
if(this.template.indexOf("Magento_Checkout/cart/") > -1){
debugger;
}
return !!this.template;
},
...
But template "Magento_Checkout/cart/shipping-estimation" is gone for there are many products on the cart.
