And it wont populate the unchecked ones... which means if each checkbox
doesnt have a unique value (ie: they all have value "true" or "on") you will
get an array containing n instances of "on" where n is equal to the number
of checked checkboxes of that name. Not very helpful.
Best bet is to give them individual values, or individual names, so you can
tell them apart when submitted.
ie: submission of the following:
<input type="checkbox" name="bob" value="on" checked="checked"/>
<input type="checkbox" name="bob" value="on"/>
<input type="checkbox" name="bob" value="on" checked="checked"/>
<input type="checkbox" name="bob" value="on" checked="checked"/>
<input type="checkbox" name="bob" value="on" checked="checked"/>
will give you:
bob == String[] { "on","on","on","on" }
The idea is to use something like:
<input type="checkbox" name="bob" value="1" checked="checked"/>
<input type="checkbox" name="bob" value="2"/>
<input type="checkbox" name="bob" value="3" checked="checked"/>
<input type="checkbox" name="bob" value="4" checked="checked"/>
<input type="checkbox" name="bob" value="5" checked="checked"/>
which will give you:
bob == String[] { "1","3","4","5" }
OR
<input type="checkbox" name="bob1" value="on" checked="checked"/>
<input type="checkbox" name="bob2" value="on"/>
<input type="checkbox" name="bob3" value="on" checked="checked"/>
<input type="checkbox" name="bob4" value="on" checked="checked"/>
<input type="checkbox" name="bob5" value="on" checked="checked"/>
bob1 == "on"
bob2 == null (assuming you reset it or its a request scoped form etc...)
bob3 == "on"
bob4 == "on"
bob5 == "on"
OR (maybe)
You could probably make use of indexed property names too (and init the
array of appropriate length in the reset method)
<input type="checkbox" name="bob[0]" value="on" checked="checked"/>
<input type="checkbox" name="bob[1]" value="on"/>
<input type="checkbox" name="bob[2]" value="on" checked="checked"/>
<input type="checkbox" name="bob[3]" value="on" checked="checked"/>
<input type="checkbox" name="bob[4]" value="on" checked="checked"/>
to get:
bob == String[] { "on",null,"on","on","on" }
Though I havent tried this variant, so I could be wrong, or the semantics
could be subtly different!

hi
Just declare a property field with the datatype as array like
String[] mycheckBox
It will automatically populate all of the checkbox selected into the array
property
