I wanted store the selected values from a multiple choice listbox into a databse field (as the comma delimited list that HTML forms post natively). And correctly highlight the selected values in the listbox when the user returns to edit the record. I have done this before with ASP and CCS2. PHP version for some reason only returns the first value.
I ended up needing to modify 2 sections of clsControl in Classes.php:
This is the modified clsControl GetValue() function:
function GetValue()
{
if($this->ControlType == ccsCheckBox)
$value = ($this->Value) ? $this->CheckedValue : $this->UncheckedValue;
else if($this->Multiple && is_array($this->Value)){
//$value = $this->Value[0];
$strValues="";
foreach ($this->Value as $col_value) {
$strValues=$strValues.$col_value.",";
}
$strValues=substr($strValues, 0, Strlen($strValues)-1);
$value = $strValues;
}
else
$value = $this->Value;
return $value;
}
This is the modified case ccsListbox statement in the Show function:
case ccsListBox:
$Options = "";
if(is_array($this->Values))
{
//2-12-04 Brandon Burnett Added this if clause because this->value isn't treated as an array without it
if($this->Multiple){
$this->Value = explode(",",$this->Value);
}
for($i = 0; $i < sizeof($this->Values); $i++)
{
$Value = $this->Values[$i][0];
$TextValue = htmlspecialchars(CCFormatValue($Value, $this->Format, $this->DataType));
$Text = htmlspecialchars($this->Values[$i][1]);
if($this->Multiple && is_array($this->Value)) {
$Selected = "";
for($j = 0; $j < sizeof($this->Value); $j++){
if($Value == $this->Value[$j]){
$Selected = " SELECTED";
}
}
}
else {
$Selected = ($Value == $this->Value) ? " SELECTED" : "";
}
$Options .= "<OPTION VALUE=\"" . $TextValue . "\"" . $Selected . ">" . $Text . "</OPTION>\n";
}
}
$Tpl->SetVar($this->Name . "_Options", $Options);
$Tpl->ParseSafe($this->BlockName, false);
break;

We have related example in CCS Example Pack: "Updating Many-to-Many via CheckBox List".
This works without any modifications to common files.
The data in our example is stored little differently but this shouldn't matter.

 boss.. your solutions are not very complete..I would suggest... that you change this functionality asap... I suppose... you should have a function on the micro level to handle HTML Arrays... and list boxes..I am haveing a lot of trouble..cause..of that.

Hi,
when will this be fixed? The "Updating Many-to-Many via CheckBox List" is not really a solution!
Regards
Stefan

Please specify how you would you like this to be "fixed", and submit a detailed suggestion to our Support, or the Wishes forum.
Thanks

See the posting from Ramu. If we use it like the example we have to write a lot of code and i think Codecharge Studio is a code generator

Stefan,
OK... but I don't know which method Ramu would like to use. And I don't know if his method would be the one desired by most people, or if it even makes sense.
We already have good experience and we know that there are several ways of handling multi-select data & many-to many relations.
The main reason that multi-select Listbox wasn't automated yet is that there are too many variables and everyone may want to handle it differently.
BTW, storing such data in comma-delimited field is one of the less common methods to handle this. We specifically didn't want to do this because we don't want to suggest such method to the users.

Peter,
yes, i see it as you describe it but i think if you give us a one solution - as it is, for example we need a table where the relations for a multiple listbox are stored, like the example "Multiple Listbox" we would save a lot of time.
I don't believe that you have to support all ways of handling this, i think one defined solution is enough and i think this is a way where we all can live with it.
Greetings from Munich, Germany
