I would like to use the advanced search on my home page, it works fine if I click the advanced search link in the footer at the bottom. But if I add

{{block class="Magento\CatalogSearch\Block\Advanced\Form" template="Magento_CatalogSearch::advanced/form.phtml"}}

to my home page, the search results are all 404?


You cannot achieve your request like this way

You get the issue like 404 because of the form post URL of home page advanced search is : www.example.com/cms/index/result which is a 404 page at Magento.

And form Post URL defined at getSearchPostUrl()

 public function getSearchPostUrl()
        return $this->getUrl('*/*/result');

So you have to change it to full URL

 public function getSearchPostUrl()
        return $this->getUrl('catalogsearch/advanced/result');

So, you have to create a plugin at on this method which change url to $this->getUrl('catalogsearch/advanced/result');

Create a custom module and define plugin at di.xml app/code/{Vendor}/{Modulename}/etc/frontend.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <type name="Magento\CatalogSearch\Block\Advanced\Form">
        <plugin name="change_post_url" sortOrder="1"
                type="{Vendor}\{Modulename}\Plugin\FormPlugin" />

Plugin class located at FormPlugin.php app/code/{Vendor}/{Modulename}/Plugin/

namespace {Vendor}\{Modulename}\Plugin;

class FormPlugin

    public function afterGetSearchPostUrl(\Magento\CatalogSearch\Block\Advanced\Form $subject, $result)
        return $subject->getUrl('catalogsearch/advanced/result');

Also, this module should have:

  1. app/code/{Vendor}/{Modulename}/etc/module.xml.
  2. app/code/{Vendor}/{Modulename}/composer.json
  3. . app/code/{Vendor}/{Modulename}/registration.php.

After do module enabled and setup upgrade, Di compile, Static content deploy After adding the event you should flush the cache.

The Module structure will like
