I have 3 checkboxes :
<input class="shoesChoice" name="trendy" type="checkbox" />
<input class="shoesChoice" name="luxury" type="checkbox" />
<input class="shoesChoice" name="sports" type="checkbox" />
And I want to store this information into (if possible) only one field in my database. So, if the 1rst and the last input are checked, my shoesChoice field should have : "trendy, sports"
