appending to an array

[jchapa72]

I want to update a bunch of records at once. Basically I have a website where subjects are assigned to researchers for a psychological study. Once the subject has completed the study, the researcher logs in to indicate which subjects have participated and which ones have not. One researcher has as many as 800 subjects.

Each record (subject) has a radio button named using an array notation....participated[SubjectUIN] with values of yes or no with no checked as the default value.

Here is that part of the code:

_<input type=\"radio\" name=\"participated[SubjectUIN]\" value=\"Yes\"";
_ if($subjects_row[Participated]=="Yes") {
_ _echo("checked");
_} 
_echo " /> Yes
_ _ _ _
_<input type=\"radio\" name=\"participated[SubjectUIN]\" value=\"No\" ";
_ if($subjects_row[Participated]=="No") {
_ _echo("checked");
_} 
_echo " /> No

If the researchers click on Yes for a particular subject, how can I add that response to the "participated" array.

Basically, on the following page I want to be able to update the database using this array. For example:

foreach ($_POST['participated'] AS $subjectUIN => $participated)
__mysql_query("UPDATE subjects SET Participated='$participated' WHERE SubjectUIN='$subjectUIN'") or die(mysql_error(

am not sure if this is a solution for u...but i guess that all the checked check boxes are automatically submitted. so all the subjects for whom the researcher clicks on yes, will be submitted in the participated array(those not clicked will not be). so i dont think u need to add anything any where.
however if this is not what u are looking for... get back with a bit more details... if thats possible 🙂
