I have a html form atm that is able to write and append data into a csv file that already exists using PHP, but I want to add code in so that it checks to see if the csv file already exists, and if it doesn't, to create it and make it writeable, and insert the relevant column headings.
this is the code atm:
<?php
if($_POST['formSubmit'] == "Submit")
{
$errorMessage = "";
if(empty($_POST['formMovie']))
{
$errorMessage .= "<li>You forgot to enter a movie!</li>";
}
if(empty($_POST['formName']))
{
$errorMessage .= "<li>You forgot to enter a name!</li>";
}
$varMovie = $_POST['formMovie'];
$varName = $_POST['formName'];
if(empty($errorMessage))
{
$fs = fopen("mydata.csv","a");
fwrite($fs,$varName . ", " . $varMovie . "\n");
fclose($fs);
header("Location: thank-you.html");
exit;
}
}
?>
