How can i fit this comma problem with CSV file? - php

Question

I have this code that creates a CVS file with the CF7 information the customer has provided, and it is attached into the mail I receive, the code is into functions.php.
The problem I have is that if a customer puts a comma into any field, like if he put on the name field John, Smith, it breaks the CSV
Do you have any idea how can I fix it?
//Create the shortcode which will set the value for the DTX field
function cf7dtx_counter(){
$val = get_option( CF7_COUNTER, 0) + 1; //Increment the current count
return $val;
}
add_shortcode('CF7_counter', 'cf7dtx_counter');
//Action performed when the mail is actually sent by CF7
function cf7dtx_increment_mail_counter(){
$val = get_option( CF7_COUNTER, 0) + 1; //Increment the current count
update_option(CF7_COUNTER, $val); //Update the settings with the new count
}
add_action('wpcf7_mail_sent', 'cf7dtx_increment_mail_counter');
// Add this to functions.php //
// Create CSV by scraping email using before_send_mail action //
add_action( 'wpcf7_before_send_mail', 'cf7_csv_creation' );
function cf7_csv_creation($cf7) {
// Allow to target the ID of specific form //
$form_id = $cf7->id();
// Check certain form by ID - remove this IF statement if not specific //
// Make sure the file is saved into wp-content to retieve it within WPCF7 settings as an attachement //
$user_register_csv = 'wp-content/uploads/csvs/csvreserva.csv';
// Create file contents - if you have more fields add them to the output below //

I think the guy that commented on you post has a better solution but alternatively you can add this line before you assign a value to $output
$_POST = str_replace(",","",$_POST);
This will replace all the commas in $_POST with an empty character so even if the user enters a comma it will get replaced with an empty character.
If you want to keep the commas that the user enters, you can enclose the $_POST variable in quotation marks when extending the value of the $output variable. For example:
$output .= '"'.$_POST["residencia"].'", ';
