  • Autopopulate from Select box from database

    - by Chris Spalton
    hope you can help, please forgive any poor coding or anytihng, I'm new to this and just hacking my way through to get things to work. That said, on one of my projects I have this code, which successfully populates the dropdown from a database when the page is loaded: <select name="Region" id="Region"> <option value="">-- Select Region --</option> <?php $region=$POST['Region']; if ($region); { $regionquery = "SELECT DISTINCT REGION FROM Sales_Execs "; $regionresult = mysql_query($regionquery); while($row = mysql_fetch_array($regionresult)) { echo "<option value=\"".$row['REGION']."\">".$row['REGION']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Region').value = <?php echo json_encode(trim($_POST['Region']));?>; </script> </select> On my next project that I'm working on now, I need to do the same thing, so I copied the above code amended, and placed in my new project: <select name="Sales_Exec" id="Sales_Exec"> <option value="">-- Select SE --</option> <?php $salesexec=$POST['Sales_Exec']; if ($salesexec); { $salesexecquery = "SELECT DISTINCT Assigned FROM Data "; $salesexecresult = mysql_query($salesexecquery); while($row = mysql_fetch_array($salesexecresult)) { echo "<option value=\"".$row['ASSIGNED']."\">".$row['ASSIGNED']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Sales_Exec').value = <?php echo json_encode(trim($_POST['Sales_Exec']));?>; </script> </select> This second chunk of code doesn't work... and I can't work out why as it seems I've copied it all and amended all the neccersary parts, can anyone spot what is wrong? Thankyou!

  • Rails: Serializing objects in a database?

    - by keruilin
    I'm looking for some general guidance on serializing objects in a database. What are serialized objects? What are some best-practice scenarios for serializing objects in a DB? What attributes do you use when creating the column in the DB so you can use a serialized object? How to save a serialized object? And how to access the serialized object and its attributes? (Using hashes?)

  • ASP.NET MVC model state as text

    - by David Moorhouse
    Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?

  • How to use vim's syntax files in emacs to color the text

    - by Vijayender
    Are there any snippets to make emacs use the .vim syntax files found in /usr/share/vim/vimfiles/ for coloring text. Many applications like conky have the vim syntax files like "conkyrc.vim" for vim but not for emacs. So is there an easy way to use those files rather than rewriting a new language-mode for each of those available in vimfiles directory.

  • How do I clone an OpenLDAP database

    - by elzapp
    I know this is more like a serverfault question than a stackoverflow question, but since serverfault isn't up yet, here I go: I'm supposed to move an application from one redhat server to another, and without very good knowledge of the internal workings of the application, how would I move the OpenLDAP database from the one machine to the other, with schemas and all. What files would I need to copy over? I believe the setup is pretty standard.
