  In your query template, you could use the value from one of your shapefile columns or database columns to build a URL.  

  Something like:  

  <a href="http://myserver.com/mydir/[IMAGENAME]">[IMAGENAME]</a>  

  or 

  <a href=http://myserver.com/mydir/[IMAGENUMBER].img>[IMAGENUMBER].img</a>  


  If you wanted to use a URL to send the user directly from a map click to the image, you could use:

  TEMPLATE "http://myserver.com/mydir/[IMAGENUMBER].img"  

  **note, URL templates only work in mode=query, NOT in mode=nquery!

  David.

    I probably want the second way. A difference is that the clickable links are not exactly the same as the attribute values in the index, because I have to change a UNIX file path (e.g., /home/MyDir/1.img) to a Web-accessible path (e.g., http://SomeWeb/MyDir/1.img).


    Thanks,
    Xiaopeng

      Are you interested in having the user click on the map and be directed automatically to another Web page?  This could be done using a URL as a query template and setting the mode to query.  

      Or, do you want the user to click on the map, presumably as a query and return a page or text on the existing page that includes a list of clickable links?  

      David.

        Jacob, thank for your reply. 
        I think your method generates hyperlinks after post-processing of query result. But I wonder if it is possible to return hyperlinks to a uer directly when he/she clicks on the map. I wonder it is possible?


        Thanks,
        Xiaopeng

          Hi Xiaopeng,

          If the attribute value is simply passed into the HTML, then it's simply a matter of putting in the right HTML code:

          <a href="http://someWebsite/myDir/1.img" target=#>Click for 1.img</a>  (the target=# makes it open in a new window)

          I normally generate a directory listing, and paste it into a spreadsheet (e.g. excel / openOffice CALC), and split up the parts of the link, then concatenate them. For example, imagine a row in a spreadsheet:

          column 1:      <a href="http://someWebsite/mydir/
          column 2:      1
          column 3:      ".img target=#>
          column 4:      click for image 
          column 5:      1
          column 6:     </a>

          column 7:     =concatenate(column1, column2, column3, column4, column6)

          Only column 2 and 5 will change (can use autonumber). All other columns will hold the same value, and can be copied across.

          Hope this makes sense.

          regards,

          Jacob

            I have one index on raster images and it can be displayed and queried through Mapserver.
            I wonder whether it would be possible to generate a hyperlink in query result.
            The hyperlink will be generated based on one attribute in the index. 
            For example, if the attribute value is "/home/myDir/1.img", the hyperlink will direct user to http://SomeWebsite/myDir/1.img".
            I appreciate any suggestions or ideas.

            Thank you



            Best regards,
            Xiaopeng
