mmm, maybe you can trigger the layer selection by using the filter
layer_select=layer_to_select_1,layer_to_select_2,... at the same time you do
the layer reorder call.
if im not wrong, the filter will trigger the layer selection before
layerReorder is called, meaning the layers *should* be in selectedMsLayerIds

Hi Oliver
On line 478 I have : $this->orderedMsLayerIds[] =
$this->selectedMsLayerIds[$id];
Cartoweb can't find the $id index in the selectedMsLayerIds collection.
I made a print_r of the selectedMsLayerIds collection and i miss a layer that
i checked by javascript chargeVue() function. So i assumed that Cartoweb needs
first a CartoWeb.trigger('Layers.LayerShowHide'); call to gather the layers
checked in the tree and update its collection. And only then, i can make the
CartoWeb.trigger('LayerReorder.Apply'); to reorder these layers.
The problem is that i want to do that in only 1 ajax call. I'd like to avoid
writing a new plugin. What could you advise me?
Thanks for your help.

what do you have at line 478 of your ClientLayerReorder.php file?
I only see a comment at that line

Subject: [Cartoweb-users] Show layers in a defined order
Hi everyone.
I'm trying to do a 2 in 1 action with Cartoweb: Show some layers in a
special order. So it means i have to check some layers in the layers tree and
reorder them. Finally i make the ajax call to make Cartoweb apply the changes.
The problem is Cartoweb seems not to know the layers i just checked.
Here's the error message.
version: 3.3.0 [$Revision: 1.2 $]
class: CartocommonException
message: Error [8, Undefined index: 1,
/opt/cartoweb/cartoweb3/projects/aeag/plugins/layerReorder/client/ClientLayerReorder.php,
478]
So here's the function i made to do this.
function chargeVue() {
// Here i get the layers i need to show in a field of my form
for (var i=0; i<$('selectVue').options.length; i++) {
if ($('selectVue').options[i].selected ) {
selectione = $('selectVue').options[i].value;
}
}
// Here i check the layers i got in the layer tree
var tabSel = $('vue_'+selectione).value.split(";");
var tabOrdre = new Array();
var celts = $('layersroot').getElementsByTagName('input');
for (var j = 0; j < celts.length; j++) {
if (!celts[j].checked && inArray(tabSel,celts[j].value)) {
celts[j].checked = true;
// Here i store the order of the layers in the layers tree
tabOrdre.push(celts[j].value);
}else
celts[j].checked = false;
}
// Here i fill an array with the new layers order
var tabNewOrdre = new Array();
for (j = 0; j < tabSel.length; j++) {
// Ajoute l'indice de la couche dans tabOrdre
tabNewOrdre.push(indexInArray(tabOrdre,tabSel[j]));
}
$('layersReorder').value = tabNewOrdre.join(",");
// Here i update the map
CartoWeb.trigger('Layers.LayerShowHide');
}
Is there a way to achieve this without making 2 ajax calls (one to check
the layers, the other to order them)?
Thanks for your help
