Hello again Linda,
You will need to run a validation of each field to see it is empty or
not. Simple enough. I will give you the most basic format to do this.
<?php
// Set default error flags.
$is_error = false;
$is_error_field_name = false;
// Check to see if Fields are Empty
// If true, flag error boolean
if(empty($_POST['field_name'])){
$is_error = true;
$is_error_field_name = true;
}
// Place this where your error message belongs in your mark up. I
usually create an include file and place it above the form.
// General form error
if($is_error)
echo '<p class="error">Oops! There is a problem. Make sure all
your fields are completed.</p>';
// Custom form error
if($is_error_form_field)
echo '<p class="error">• There appears to be problem with
FORM_FIELD_NAME.</p>';
?>
As a general rule, I tend to place my validation and insert/update code
into the upper area of the document. This keeps everything in one file:
validation, processing, the form, error messaging and successful
confirmation. Using the flags set in the error validation section, I can
tell the script what to display after the form has been submitted.
Is this any clearer?
