<?php // get form input $type = $_POST['selType']; $color = $_POST['txtColor']; // use form input echo "Your $color $type is ready. Safe driving!"; ?>

Hello friend,
So, the main case of this error is that the variable $_POST that you trying put in variable is undefined. But this error is just a Notice…

To make right, look…

try use the ternary…

<?php $type = isset($_POST['selType']) ? $_POST['selType'] : ''"; $color = isset($_POST['txtColor']) ? $_POST['txtColor'] : ""; echo "Your $color $type is ready. Safe driving!"; ?>

So, ternary is equal “if, else”, in this case… if ( isset ( $_POST[‘txtColor’] ) ) { $type = $_POST[‘txtColor’] } else { $type = “” }

Thank you, I hope that this code can help you.

Ohhh, I forgot…

The name of this is “validation” :))

thank you so much for this… ill try this right away… :slight_smile:
