This time round I decided that all that cutting and pasting of form tags into the php page (and their layout) was a waste of time so I created a couple of database tables to tell the template which fields to include. So given the form name the template creates the rest of the page.
<?php
$sql="select form_caption, update_file, ok_function, validate_function
from schema_forms
where form_name = '$FormName';
select field_name, field_type, field_caption, span_name, needs_validation, can_hide, select_sql, allow_blank,
block_numbers, allow_decimal, allow_negative
from schema_form_fields
where form_name = '$FormName'
order by field_number;";
if (!isset($link)) {
include("connectioni.php");
}
if (!mysqli_multi_query($link,$sql)) {
echo "<p>" . mysqli_error($link) . ". Unable to load property list.</p>";
}
else {
do {
if ($result = mysqli_store_result($link)) {
$finfo = mysqli_fetch_field($result);
if ($finfo->name=="form_caption") {
$row=mysqli_fetch_array($result, MYSQLI_BOTH);
$FormCaption=$row["form_caption"];
$UpdateFile=$row["update_file"];
$OKFunction=$row["ok_function"];
$ValidateFunction=$row["validate_function"];
} else {
?>

Then he tells me that there was probably a tool out there that would have done it for me! So then you just need to set the variable $FormName, include this file and write the appropriate Javascript validation function. I Ajax the lot into a floating box in the middle of the screen (pretending to be a modal dialogue box).
