Help with a script

Hey 🙂

i'm trying to acheive a script that will scan a folder for pdfs

Here is the example folder:

then, it'll create one ai file that will include all pdfs with the same prefix as links, while sorting them as shown here, into 4 different rows:

1. right sign, fron side

2. left sign, front side

3. right sign, back side

4. left sign, back side.

every sign has a back side, but not every right sign has a left parallel sign.

"1"prefix will cause sign to be placed at the top

"2" will be right after the top

etc...

it'll look like this:

someone helped me with this. his done the script,  but it works only with 2 rows (not 4 as i need) - if the pdfs contain right+ left and front + back side then it's all a mess:

Can someone understand what i'm trying to acheive or does my language barrier make it difficult?

here is the script:

// doc = app.documents.add()
var doc= app.activeDocument


//Get pdfs
pdf_folder = Folder.selectDialog()
pdfs = pdf_folder.getFiles('*.pdf')

front_side = []
back_side = []
for (var f in pdfs){
    if(pdfs[f].name.toLowerCase().search('back')!=-1){
        back_side.push(pdfs[f])
    }
    else{
        front_side.push(pdfs[f])
    }

}


//layer
itemLayer = doc.layers[0]


function newRect(x, y, width, height) {
    var l = 0;
    var t = 1;
    var r = 2;
    var b = 3;

    var rect = [];

    rect[l] = x;
    rect[t] = -y;
    rect[r] = width + x;
    rect[b] = -(height - rect[t]);

    return rect;
};

for (var f = 0; f < front_side.length; f ++){
    my_f_name = front_side[f].name.replace('.pdf','')
    placePdfOnNewAB(front_side[f],gap_ver_global,f,my_f_name)
}

    my_f_name = back_side[f].name.replace('.pdf','')

//place pdf 1st
//resize artboard if 1st artboard -> move pdf
//add new artboard -> resize -> place it underneath the previous artboard -> move pdf
