PHP checkbox传值问题

<input type="checkbox" id="check1" name="RadioGroup1[]" value="A" />
<input type="checkbox" id="check1" name="RadioGroup1[]" value="B" />
<input type="checkbox" id="check1" name="RadioGroup1[]" value="C" />
<input type="checkbox" id="check1" name="RadioGroup1[]" value="D" />

想通过post 传到相同页action里，把上边选定过的内容记录并在action自动显示刚才选定过的结果。

action里也是一样，但要自动取刚才选定过的值并勾上
<input type="checkbox" id="check1" name="RadioGroup1[]" value="A" />
<input type="checkbox" id="check1" name="RadioGroup1[]" value="B" />
<input type="checkbox" id="check1" name="RadioGroup1[]" value="C" />
<input type="checkbox" id="check1" name="RadioGroup1[]" value="D" />
