- The advantage of using a self-processing form…is that you can re-display the form with error messages…if any of the fields have errors, or if required fields…haven't been filled in.…You need two arrays to deal with errors and missing fields.…So let's begin by creating a PHP block at the top…of the page, above the doctype declaration.…And inside that PHP block, we need to initialize…two empty arrays.…So the first one will be called errors.…And the second one, missing.…
We'll come back later to the script that processes…the form input, but first let's add some error…messages to the html form and wrap each one in a…conditional statement so they're shown only when necessary.…So immediately after the h1 tag on line fourteen,…insert some space and we need a PHP block,…and inside that PHP block, we need to have a conditional…statement, so if errors…or missing.…
Now, I'm going to use the alternative syntax…for conditional statements.…So if either of these two arrays has any elements,…they'll be true, then we need to display a message…
