I'm trying to make an grid in customer, but I can't get the post of this grid.
What's is wrong?
Here is my config xml
\Vendor\Rep\view\adminhtml\layout
customer_index_edit.xml
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left"
xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="customer_form">
<block class="Vendor\Rep\Block\Adminhtml\Customer\Edit\Tab\Rep" name="customer_edit_tab_rep">
<action method="setTabLabel">
<argument name="label" xsi:type="string">Sales Representative</argument>
</action>
</block>
</referenceBlock>
</body>
vendor_rep_customer_rep.xml
<?xml version="1.0"?>
<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/layout_generic.xsd">
<container name="root" label="Root">
<block class="Vendor\Rep\Block\Adminhtml\Customer\Edit\Tab\Rep\Grid" name="customer.edit.tab.rep.grid"/>
<block class="Magento\Backend\Block\Widget\Grid\Serializer" name="related_grid_serializer">

<argument name="callback" xsi:type="string">getSelectedReps</argument>
<argument name="input_element_name" xsi:type="string">reps_ids</argument>
<argument name="reload_param_name" xsi:type="string">reps</argument>
</arguments>
</block>
</container>

Best Answer
There can be 2 possible problems:
First please make sure if your grid values are populated correctly: if you inspect HTML source below your grid, you should have hidden input with names that represent your config XML input field (in your case it should be like:
<input type="hidden" name="reps_ids" value="" id="id_SOME_GENERATED_VALUE_HERE">.First of all, make sure when you select something on the grid -> this field should be modified, and value should be updated. If data is not populated, make sure that your grid config is correct.
If the first problem is solved (or does not exists) and values are in hidden field, but are not sent with post, the problem is probably because your grid is not registered as a part of
customer_form(it is not declared insidecustomer_form.xml). If you will take a look insideform.jsto see how Magento handle the form you will see something here:There is a selector for additional fields that can be taken into the form submit. If you will debug this you will notice that
additionalFieldsselector take anything into submit that contain "form" attribute, so if you will manage to make your hidden input to contain attribute:form="customer_form", then your values should be posted with customer form. So your input should look like:You can do it by overriding
widget/grid/serializer.phtmlfor your grid only or by overriding the proper block and setting this param through it.
