@JulianB how you implement the preload/edit function?

Validation part on the property is not working. On jquery combination of :input and keyup is not a good one. A quick fix would be to change to:
$(‘#form_builder_properties li *:input’).change(function(){ …
however is not that fancy but it works.

I had a need to be able to :
preload a presaved form for add/edit. For this I added :
preload:function(){
$.get(Admin.formbuilder.BASEURL+’?action=edit&type=0′,function(result){
var into = $(“#form_builder_panel ol”);
var type = $(this).attr(‘id’);
var e = this;
$(into).prepend(result);
var $newrow = $(into).find(‘li:first’);
$newrow.hide().slideDown(‘slow’);
$(into).sortable(“refresh”);
delete result;
});

},

This will generate an ajax request and can preload a saved form..
On php you need to add after case ‘element’:

case ‘edit’: echo “here u put whatever html to echo”; break

Select options lack of Value=>Description of value option.
here I added a possibility to write it as :
val::dec of val;val1::dec of val2 and so on…

for this I added 2 functions:
function serialize_options($arr){
if (!$arr) return “”;
foreach ($arr as $key => $val){
if (is_string($val)) $my_opt.= “$key::$val;\n”;
else foreach ($val as $subkey => $subval){
$my_opt.= “$key::$subkey::$subval;\n”;
}
}
return substr($my_opt,0,-3);
}

function unserialize_options($my_opt){
$arr= explode(‘;’,$my_opt);
foreach ($arr as $key => $val){
//
$val=trim($val);
// print “$key => $val\n”;
if (strpos($val,”::”)!==FALSE){
list($Country,$Prov)=explode(“::”,$val,2);
// echo “$Country-$Prov\n”;
if (strpos($Prov,”::”)!==FALSE){
list ($sprov,$lgprov)=explode(“::”,$Prov);
$my_res[$Country][$sprov]=$lgprov;
}else{
$my_res[$Country]=$Prov;
}
}else{
$my_res[$val]=$val;
}
}
return $my_res;
}

this support val::Descr of value as well as optgroups like
USA::State 2 letter::Name of state;
Canada::BC:British Columbia (value selected BC, otpgroup Canada)

I added as well a few custom made fields like Select Country and Select State , however they were embedded in the code and not by a template how it should.
