ExtJS Store代理错误地在extraParams中使用数组构建GET请求

Question

I want to pass additional filter data to my PHP REST service, namely a set of values from a form. Form is a set of checkboxes with a same name: 'relations'.

To do this, I do the following:

var relationTypes = [],
    objectsTreeStore = Ext.getCmp('objectsTreeGrid').getStore();
if( 'relations' in this.getFilterForm().getValues() ) {
    relationTypes = typeof this.getFilterForm().getValues().relations ==='string' ? [this.getFilterForm().getValues().relations] : this.getFilterForm().getValues().relations;
}
objectsTreeStore.getProxy().extraParams.relations = relationTypes;
objectsTreeStore.load();

As example, value of relationTypes variable according to console.log is ["100_200", "110_200"].

But GET request URL is http://10.161.28.111:81/objectstree/get?branch_id=2&relations=100_200&relations=110_200&node=root.

PHP interprent this data as

Array
(
    [branch_id] => 2
    [relations] => 110_200
    [node] => root
)

I think that URL should be like http://10.161.28.111:81/objectstree/get?branch_id=2&relations[]=100_200&relations[]=110_200&node=root.

How I can solve this issue?

Answer 1

Did you try to name your checkboxes name: 'relations[]' ?

You can also use CheckboxGroup container for correct behaviour. Docs — http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.layout.container.CheckboxGroup
