How to add checkbox with multiple values in table(WordPress)?

Question

Right now i changed from options table to my own table so things are getting difficult

i have a checkbox its name is selection in table, so here is what i tried

<input type="checkbox" name="selection" value="1"<?php checked("1",$item['selection']);?> />
<input type="checkbox" name="selection" value="2"<?php checked("2",$item['selection']);?> />
<input type="checkbox" name="selection" value="3"<?php checked("3",$item['selection']);?> />

This is not saving any value , Then i tried as array in below

<input type="checkbox" name="selection[]" value="1"<?php checked("1",$item['selection']);?> />
<input type="checkbox" name="selection[]" value="2"<?php checked("2",$item['selection']);?> />
<input type="checkbox" name="selection[]" value="3"<?php checked("3",$item['selection']);?> />

It is throwing warning Warning: mysql_real_escape_string() expects parameter 1 to be string, array given

How to store multiple values with the same name in checkbox when using my own table?

Any help help would be greatful.

This is not saving any value you mean you are not getting values checked ? — Prince Singh

i suppose checked is a function and you are returning vaule with it. if thats true than you are missing an echo before your checked function

<?php echo checked("1",$item['selection']);?>

Thanks for your answer +1. But this is not working.the check box is not checked.i have only one field that is selection, so is that possible to store multiple values in this one field

When i check a multiple selection it is selecting only one which is recently selected. If there is four checkbox selected it is selecting only one out of four
