Pass URL parameters in sample viewer

AaronNash

There was a previous thread on the old forum to pass search parameters into a url string,
http://forums.esri.com/Thread.asp?c=158&f=2421&t=294907&mc=104#msgid925229
I would like to see if anyone has accomplished this for the new viewer. I have a non-spatial flex application that runs a query on a ArcServer service and returns the results into a datagrid, I then have a button that exports the results into a pdf report. I would like to have another function that takes a value from the datagrid, populates it into a URL string that opens a new browser and zooms to that selected feature.

thanks,
Aaron

Hello Aaron, thanks again for looking at my problem, It was my mistake, forgot to include the "image_path" in the output field for the query.

Got it working this morning,

Thanks again for the code.

Golden,

this is probably a new thread, but I will try to help you here. A good test to see if the URL is formatted correctly is try and access it from your browser, if you can get the image to show in a browser then you know what the URL should be. In my application I used textinput boxes to check on the URL format as it was being passed through the different stages of construction. The database that contained the image_path field had back slashes not forward slashes, and had extra spaces on the end. So to follow my workflow the first text input box imagetext would show the URL being http://gis.vernon-ct.gov/image/11000\11347.jpg (it would have like 10 extra spaces on the end also). Not sure how much of my code I gave you, but I had an itemclick function that reformatted the URL, and dumped the text in imagetexturl. The end result would be http://gis.vernon-ct.gov/image/11000/11347.jpg . If you copy and paste this text into browser the image will show up. I also created a virtual directory in IIS that pointed to my image folder. So to start you need to make sure you have a working URL string and then reconstruct that string in flashbuilder.

Aaron

Thanks Aaron for replying, i do not have the itemclick function on the code that i have,I have tried to reformat the URL string. I can access the image on my virtual director with no problems,I just can not get the image loaded from the query. Maybe i am missing something, Attched is the code that i have ro check for me if i am on the right direction.

Is this application running on your local computer? I have IIS installed on my local machine and created a virtual directory that points to the bin-debug folder of my project, I changed the output folder URL and the run/debug setting URL path to launch. So when I am testing on my local computer the application launches in a url which is http://localhost/NewViewer2.4/index.html, I can then add the search parameters http://localhost/NewViewer2.4/index.html?search=08-0025-00009 and if everything is configured correctly the search is executed. With the 2.4 version, as long as the search was configured correctly the URL string will work

Aaron, maybe you can help me on this one, i can not get the Images to load on my report.
I have made my changes as follows, referring to the code that you supplied.

<mx:VBox id="vbox0" horizontalAlign="center" visible="false">
[U]<mx:TextInput id="buildingtext" text="http://madikana/Chdmgis/{resultsGrid.selectedItem.ShortFileName}"/> <mx:Label id="urltext" text="http://madikana/Chdmgis/gisindex.html?search={resultsGrid.selectedItem.CompNme}"/>
<mx:TextInput id="buildingtexturl" text="{bldtxt}.jpg"/>
<mx:Image id="building"/>
<mx:TextInput id="imagetext" text="http://madikana/Chdmgis/Photography/{resultsGrid.selectedItem.image_path}"/> <mx:TextInput id="imagetexturl" text="{urltxt}"/>
<mx:Image id="image1" width="320" height="240"/>
</mx:VBox>

Are you able to have a look at this and tell me where i went wrong, i have created image_path field in my data attributes to store the photograph names.

How is the path for the photos formated in the attributes?

Please help.

I followed the instructions in the documentation. Are you using the enhanced search widget 2.4? If so there are no code changes to the flexviewer, everything should be configured from the search widget xml. What URL string are you using to try and search?

Aaron

Yes, i am using 2.4, i am trying to searh the following URL, http://madikana/Chdmgis/bin-debug/index.html?search=Reinbron.

To get the additional parameters, i ended up adding the following, to the "URLTEXT" text="http://madikana/Chdmgis/bin-debug/index.html?search={resultsGrid.selectedItem.OfficialNme}&slayer=0&exprnum=0&showdatagid=true".

Thanks for looking at that.

Golden,

If you are using the 2.4 api, then I would use Robert's new enhanced search widget, you can find it HERE. He was able to integrate all the code needed to accomplish exactly what was done in this forum, everything is outlined in the documentation included in the download. I am using the latest version and it was easy to configure. If you do use Robert's widget make sure you rate it on the download page

Aaron

Thanks for the quick reply, did you make any changes to the Widgetmager or the Viewercontainer?

I have been trying to get it wotking but unsucessfull?

what other steps did you follow?

Hello Aaron
Firstly, i just want to thank you for sharing the code with us, I have been following the thread and trying to use your code to achieve exacly what you want here, I see you got it solved, using the Enhansed search widget, could you please share the light with me as i am battling to get the Search zoom to the results, If possible can i refer to your Widgetmanager and the SearchWidget? I am using the 2.4 API and battling to migrate the code i put together from different threads.

Your assistance is highly appreciated.

SandraPanicucci

The following is the one I was missing. Still doesn't zoom but it is finding the BMPID and placing an icon. Thank You very much.

Sandra,

//Add this line to the postConfigHandler function
_configData = configData;
//After this line var configData:ConfigData = event.data as ConfigData;

rscheitlin

Sandra,

You need a couple of more thing in your ViewerContainer.mxml code (I forgot them in my documentation too).

//Add this private var to the top with other private vars
private var _configData:ConfigData;

//Add this line to the postConfigHandler function
_configData = configData;
//After this line var configData:ConfigData = event.data as ConfigData;

SandraPanicucci

This is what I have in ViewerContainer:
I came to the conclusion this was where the error is but I can't see anything wrong and I've been over it so often I can't see straight anymore.

public function getWidgetId(widgetLabel:String):Number
   {
    var id:Number;
    for (var i:Number = 0; i < _configData.widgets.length; i++)
    {
     if (_configData.widgets.label == widgetLabel)
      id = _configData.widgets.id;
    }
    return id;
   }

rscheitlin

Sandra,

So do you have a getWidgetId function in your ViewerContainer.mxml file? In the 2.2.10 version of my Enhanced Search Widget I have a PDF that outlines all the needed code changes to the viewer to get this to work for the eSearch widget.

I have been through the threads. I have changed the code according to URLSearch.txt in this thread and searched through a couple of other threads. The search finctionality works fine to locate my BMPID and zoom to it however when I try to pass the BMPID into the search function via the URL I'm getting the following error message. Any ideas or suggestions on what I may need to change?

http://testgis.sd.gov/server/denr/bmpEdit1/index.html?BMPID=12

For those looking how to modify the sample viewer 2.2 to support passing the bounding coordinates in the URL, Robert Scheitlin has posted code to accomplish this here:
http://forums.arcgis.com/threads/21180-Passing-Parameter-to-Flex-Viewer

SandraPanicucci

I'm back again...Robert successfully talked me through this in the 1.3 library. I'm attempting to update to 2.x and my first problem comes when trying to load the SearchWidget I get an error #2036 Load Never Completed URL: file:///C:/inetpub/wwwroot/Copy%20of%20FlexViewer/bin-debug/ I've been through the forums and nothing seems to get rid of this error.

rscheitlin

Mark,

Nope. No easier. Yes it can be added to the eSearch just more work. You could by pass the widget but what are you ultimately after? If you only want to zoom the map to the correct location and have a graphic on the screen that you can do little to nothing with, than the answer is yes you can bypass the widget. Ultimately it is worth the effort of having this integrated into your search/eSearch widget the right way, even know it is initially a pain.

MarkSmith1

Hi Robert,

Any chance this is more straight forward in the 2.2 viewer? If not, is it possible to make this work with your enhanced search widget? Is there a way to bypass the search widget and just have the viewer execute the search if it finds URL parameters?

Thanks in advance for any advice.

Mark

Aaron,

If you want to hardcode the fields than replace the whole function with this one.

public function queryPPIN(sPPIN:String):void
   {
    //hide infowindow if any
    map.infoWindow.hide();
    
    queryLayer = "http://gis.vernon-ct.gov/ArcGISweb/rest/services/Flex_Vernon/MapServer/10";
    queryExpr = "Parcels.DBO.Parcels.MBL LIKE '[value]%'";
    queryTitleField = "PARCEL ID";
    queryLinkField = "";
    
    var queryTask:QueryTask = new QueryTask(queryLayer);
    if (configSearchText.useproxy && configData.proxyUrl)
    {
     queryTask.proxyURL = configData.proxyUrl;
    }
    var query:Query = new Query();
    var pExpr:String = sPPIN.toUpperCase();
    var expr:String = queryExpr.replace("[value]", pExpr);
    
    query.where = expr;
    var strFlds:String = "field1,field2,field3";
    var flds:Array = strFlds.split(",");
    query.outFields = flds;
    query.returnGeometry = true;
    query.outSpatialReference = map.spatialReference;
    queryTask.useAMF = false; // TODO: remove when a better solution (for checking 9.3 vs 10 AGS) is ready
    queryTask.execute(query, new AsyncResponder(onResult, onFault, queryFields));
    showMessage(loadingLabel, true);
    showStateResults();
    
    // on result
    function onResult(featureSet:FeatureSet, token:XMLList = null):void
    {
     try
     {
      searchResultAC = createSearchResults(featureSet, token);
      
      // share data
      addSharedData(widgetTitle, searchResultAC);
      showMessage(selectionLabel + " " + featureSet.features.length, false);
     }
     catch (error:Error)
     {
      showMessage(error.message, false);
     }
    }
    
    //on fault
    function onFault(info:Object, token:Object = null):void
    {
     showMessage(info.toString(), false);
    }
   }

And update this line with your real field names

var strFlds:String = "field1,field2,field3";

AaronNash

I was able get the query to run, I changed the parameters

    var i:Number = 0;
    queryLayer = "http://gis.vernon-ct.gov/ArcGISweb/rest/services/Flex_Vernon/MapServer/10";
    queryExpr = "Parcels.DBO.Parcels.MBL LIKE '[value]%'";
    queryFields = configSearchText.fields;
    queryTitleField = "PARCEL ID";

now it executes the search. When i try to hardcode the queryFields' values I get error 1067: Implicit coercion of a value of type String to an unrelated type XMLList. If I leave the values you provided configSearchText.fields, it does not query. If i remove the, it works.

rscheitlin

Aaron,

Try changing this line in the queryPPIN function from:

var i:Number = cboLayerText.selectedIndex;

var i:Number = 0;

AaronNash

I put the break point there

public function queryPPIN(xPPIN:String):void

at that point the xPPIN is still populated with the correct text, once you step forward it jumps straight to

function onFault(info:Object, token:Object = null):void

xPPIN is still populated with the correct text, but most of the other fields are null
