I have 2 sets of 4 input fields in my HTML Form. I expect to eventually have over 20 sets but have provided just 2 for this example.
Is it possible if a "set" of fields is incomplete that I can just remove that row from my resultant $all variable. So instead of having a row with the data '| | | |' it would just be completely blank.
It would just help clean things up.
Would this be easy enough to achieve?
Here is my current stuff.php script I'm using to test.
<html>
<head>
<title>Test PHP</title>
</head>
<body>
<?php
if (isset($_POST['sendform'])) {
$ierrors = array();
$all = '';
// Loop over the values 1 through 2
foreach( range( 1, 2) as $i)
{
// Create an array that stores all of the values for the current number
$values = array(
'p' . $i . 'height' => $_POST['p' . $i . 'height'],
'p' . $i . 'width' => $_POST['p' . $i . 'width'],
'p' . $i . 'length' => $_POST['p' . $i . 'length'],
'p' . $i . 'weight' => $_POST['p' . $i . 'weight']
);
// Validate every value
foreach( $values as $key => $value)
{
if( empty( $value))
{
$ierrors[] = "Value $key is not set";
}
// You can add more validation in here, such as:
if( !is_numeric( $value))
{
$ierrors[] = "Value $key contains an invalid value '$value'";
}
}
// Join all of the values together to produce the desired output
$all .= implode( '|', $values) . "
";
}
var_dump($all);
}
?>

Many thanks for any pointers. Been struggling with this for a while now.
