Functions

[terthon]

is it possible to create your own functions that have, say 4 vars, but only 2 are required? can i make it so that only the 2 required vars are needed without getting an error?

Yes, but you don't want to do that if you ever plan to read your code in a few weeks time.

Thats not too hard. Here is an example: The function only requires the two parametrs specified in the function header, $fieldName and $fieldValue. However, you can send more variables and retreive them by getting ALL the parameters with the func_get_args() .. Keep in mind that you need to "skip" those in the parameter list. The comments specify what I indend for the paramter list to be. Keep in mind the order is important when retreiving the additional parameters!

Hope that helps

//*******
// printCheckBox: returns the code for a checkbox
// Parameters:
// fieldName - name for the field
// fieldValue - value for field
// Arg 2 - checked
// Arg 3 - label for display after checkbox
// Arg 4 - string of additional params (Ex "style='color:red;'")
//******
function printCheckBox($fieldName, $fieldValue) {
$aArgs = func_get_args();
$fieldName = "name=\"$fieldName\"";
$fieldValue = " value=\"$fieldValue\"";
$checked = ($aArgs[2] == 1) ? "checked" : "";
$label = ($aArgs[3] != "") ? "$aArgs[3]\n" : "";
$addParams = ($aArgs[4] != "") ? "$aArgs[4]" : "";
return ttIndentStr(0) . ( "<input type=\"checkbox\" $fieldName $fieldValue $checked $addParams>$label");
}
