Needs to be set up on the server rather than a mail client (a distinction blurred by outlook etc.)

Set up on alias – dwinton. Double check functionality.

Say you have a javascript object eg

function myobject(){
  this.height = "180";
  this.weight = "90";
}

You can access these properties in two ways; the standard myobject.weight OR myobject["weight"]

The second way allows access to a variable using a string which is very useful

var objectVariables = ["height","weight"];

for(var i=0; i<objectVariables.length; i++){
  alert(myobject[objectVariables[i]]);
}

Which allows you to loop through an object’s variables and perform standard operations.

One slight tweak to standard checkboxes when you want to pass multiple selections of the same variable …

<input type='checkbox' name='myvariable[]' value='0' />

Notice the SQUARE BRACKETS at the end of the variable name. This tells the browser to send the variables in an array.

You can then use standard array handling functions in your php to strip the values out of:

$myvariables = $_POST['myvariable']

Rather than import data to a form, import it to a collection of javascript objects – the same objects you’ve already created to display database information.

Then use the parent object to carry out display / query creation behaviours. Much more elegant.
