the solution is javascript-based rather than php-based.
Just put this code....and when you submit, the value you'll process stored
in variable hidden_list_selected. each value selected are separated by comma
delimiter.
<html>
<head>
<script language="javascript">
function insert(thisObject){
thisForm = eval("document.frmInput");
thisForm.hidden_list_selected.value = "";
// flag to put comma as separate variable for each
selected category
flag_first = true;
for(counter=0;counter<thisObject.options.length;counter++){
if(thisObject.options[counter].selected){
if(flag_first)
flag_first = false;
else
thisForm.hidden_list_selected.value+= ",";
thisForm.hidden_list_selected.value+=thisObject[counter].value;
}
}
}
</script>
</head>
<body>
<form name="frmInput" method="post" action="testAction.php">
<select name="sel_category" multiple size="4"
onChange="javascript:insert(this);">
<option value="Fruit">Fruit</option>
<option value="vegetables">Vegetables</option>
<option value="fish">Fish</option>
</select>
<input type="text" name="hidden_list_selected" value="">
<input type="submit">
</form>
</body>
</html>

Subject: [PHP] Multiple Selection.
If i'm going to let users select multiple choices from a list in a form, let
say the part in the form is like this:
<select name="category" multiple size="4">
<option value="Praise">Fruit</option>
<option value="Worship">Vegetables</option>
<option value="Fellowship">Fish</option>
</select>
what code should i put in the submit part of the php to collect the multiple
inputs? I tried array, but it seems not working. Please help.
Thanks.
