Updating all multiple linked files

When I put an alert on it, when looping Illustrator says [Placed File].  This may be why it can't find the file?

var orderNumber = "99999" 

var doc = app.activeDocument; 

var plc = doc.placedItems; 

for(var i=0; i<plc.length;i++){ 

    alert (plc);

}

I have 5 placed images in a illustrator pdf.  On open I want to update the path to where they are linked.  I already have a prompt in place for the orderNumber so when the script runs it does as follows.  As well all of the links will be previously named the same.  i.e. front.jpg - back.jpg

prompt - Order Number

open(orderNumber);

updateLinks to - Path (File ("file://User/Desktop/" + orderNumber + "/" "LinkedImages/")

And if it helps, since they are previously named we can access them by name for update.  Let me know.

Hello jeremy, I think it can help you,

To select all files with the same name on the list of this script, double-click it.

This script works only with selected links if you do not select anything it will work with all document links.

if (app.documents.length > 0){


var doc = app.activeDocument;




if (doc.placedItems.length > 0){


var winLinks = new Window ('dialog', 'Replace Links');


var listLinks = winLinks.add ('ListBox', undefined, '', {multiselect: true, numberOfColumns: 2, showHeaders: true, columnTitles: ['Index', 'Files']});
listLinks.maximumSize = [400, 400];


var btnRelink = winLinks.add ('button', undefined, 'Relink');


var Relink = function(){


if (doc.selection.length < 1){
   
for ( i = 0; i < app.activeDocument.placedItems.length; i++ ) {
placedArt = app.activeDocument.placedItems;

placedArt.selected = !(placedArt.selected);
};


app.redraw();


};


    var strLinkItem = new Array(new Array());
    for (i=0;i<doc.placedItems.length;i++){


if(doc.placedItems.selected){

       
    var sliceString = String(doc.placedItems.file);

    var sliceThisString = sliceString.slice(sliceString.lastIndexOf('/') + 1, sliceString.length);
   
    strLinkItem = [sliceThisString];

   
    for (x=0; x<1;x++){
        strLinkItem[1] = i;

        };


}else{


    strLinkItem = ["Empty"];

   
    for (x=0; x<1;x++){
        strLinkItem[1] = i;

        };


        };
       
    };


strLinkItem.sort();


for (i=0; i<strLinkItem.length; i++){


if (strLinkItem[0] != "Empty"){

    var linkItem = listLinks.add('item', strLinkItem[1]);

    linkItem.subItems[0].text = strLinkItem[0];

};


};


listLinks.selection = [0];


};


btnRelink.onClick = function() {
   
    var newFile = File.openDialog ('Select the file that will replace the selected links.');
    if (newFile){
       
    var vetorSel = new Array();
    for(c=0; c < listLinks.items.length; c++){
        vetorSel.push(listLinks.items);
    };       
       
    for (z=0; z<listLinks.selection.length; z++){
        doc.placedItems[listLinks.selection].file = newFile;
        };
   
        for (k=0; k < vetorSel.length; k++){
            doc.placedItems[vetorSel].selected = true;
            };
       
        listLinks.removeAll();
        app.redraw();
        Relink();


    };
    };


listLinks.onDoubleClick = function (){


if (listLinks.selection != null){
   
    var totalList = listLinks.selection.length;
   
    var itemName = String(listLinks.selection[(totalList - 1)].subItems[0]);
   
    if (totalList = 1){
    var newSel = [];
    };


        for (a=0; a<listLinks.items.length; a++){
            if(listLinks.items.subItems[0] == itemName){

                newSel.push(listLinks.items.index);

                };
        };
    listLinks.selection = newSel;
    };


};






winLinks.show(Relink());


}else{alert("Any link in the current document.")};


}else{alert("No file is currently open.")};

Enjoy it.

Best regards...
