Checkbox display

Ok, I'm new to using Tinybutstrong.  I've gone through the example code and the forum looking for the answer but haven't been able to come up with the right combination of things to make this work for me.
I'm trying to click a checbox in a form, and have that box checked when redisplayed.  It works in the test_funny code from the forum, but I can't seem to get the key right.  Any help would be appreciated.
I've tried to pre define the array with keys and values but it hasn't helped.


$target_type = array("0"=>"","1"=>"","2"=>"","3"=>"");
----------
HTML
<table align="center" border="0" width="100%">
<tr><td align="left"><input type="checkbox" name="target_type[0]" value="0"  [blktype.0;if [val]='0';then 'checked'] />&nbsp;Profile Type</td>
<td align="left"><input type="checkbox" name="target_type[1]" value="1" [blktype.1;if [val]='1';then 'checked']/>&nbsp;Personal Profiles</td><td>&nbsp;&nbsp;&nbsp;</td>

PHP

$target_type[]        = trim(strip_tags($_POST["target_type"]));

$TBS->MergeBlock('blktype', 'array', $target_type);

phpinfo()
_POST["target_type"] Array
(
    [0] => 0
    [1] => 1
)

Tinybutstrong error messages

TinyButStrong Error in field [blktype.0...] : item '0' is not an existing key in the array. This message can be cancelled using parameter 'noerr'.

TinyButStrong Error in field [blktype.1...] : item '1' is not an existing key in the array. This message can be cancelled using parameter 'noerr'.


The form when re-displayed dose not show the boxes checked.

Hi TomS,

In your PHP snippet, TBS expects to have data which is an array of arrays. Each item of $target_type is supposed to be an array itself having the column named "0", "1"... Which is not.
TBS can merge single arrays but you have to use keywords "val" and "key" as virtual columns in the HTML side.

To have youe snippet working you can do like this:
HTML:
PHP:
delete the line with MergeBlock.

Thank you for the reply.  I have tried what you suggested but with the same results.  I'm trying to convert an existing php form to use Tinybutstrong, so I'm changing and testing one field at a time.
I've tried adding single quotes around the key value as shown in the Tinybutstrong manual, but that has not fixed the problem.
