Question

I have been trying to make it work with either fwrite or fputcsv but i always get the errors pointing to parameters. I am newbie in php but I try to experiment and see what it does. but so far it doesn’t either work because of parameters or not writing to the file (nothing on csv file).

I have one big problem. How to have text appear in columns (name, email and comments) while writing all data into three columns?

$csvData = array($name,$email,$comment);
        foreach($csvData as $key => $val)
        {
            $strVal = $val;

        }
        print $strVal;
        $fileHandle="";
        $filename='I-have-question.csv';
        if(!file_exists($filename)){
            $fileHandle = fopen($filename, "a+");
        }

        fwrite($fileHandle, $strVal);
        fclose($fileHandle);

insight/guide would be appreciated. thanks

EDIT

$name=$_POST['contactName'];
        $email=$_POST['email'];
        $comment=$_POST['comment'];


        $csvData = array($name,$email,$comment);
        $csvCol = array ('name', 'email', 'comment');

        $strVal='';
        foreach($csvData as $key => $val)
        {
            $strVal .= $val;

        }
        print $strVal;
        $fileHandle="";
        $filename='I-have-question.csv';

            $fileHandle = fopen($filename, "a+");


        fputcsv($filehandle,$csvData);
        fclose($fileHandle);

Now error says: Warning: fputcsv() expects parameter 1 to be resource, null. I changed according to two inputs. But it doesnt go well.

EDIT #2

Thank you, @Baba and @Quasdunk for the inputs. The only question left is how to bring in the array for $csvCol to be appended to the first row for each column so that the csvData can be appended/written after that. Only once for csvcol. how do I go about it?

EDIT #3
Thank you very much for the help. I investigated on downloading csv from the browser after the user click on the link – is it possible to do that in that same code? or I hardcode the link to the csv? Just wonder. I saw somewhere about downloadable csv where I click submit button and then the file pop up to be saved – thats not what I want but I only need the csv file to be downloaded from the server via the link.

EDIT #4

Thank you, @Baba and @Quasdunk for the inputs again.

 if(isset($_POST[$interest]))
    { 
      foreach ($interest as $interests)
       {
            $interest = $interests . " ,";
       }
    }

then in csv, it showed “array”, not values of checkboxes, i.e. 1, 2,3,4

$csvData = array($name,$email,$comment,array($interest));

Where have I gone wrong with this?

EDIT #5

Thank you very much, @Baba. I have last question
Do you know by chance how to pass the variable to mail()? For example, after csv is made/written, then mail() should send all the data to user/admin.

So far I got it working but the interest still doesn’t show the selected checkboxes – instead print “Array” similar to csv.

$interest=$_POST[‘interests’];

this is above the forceheader function.

$emailTo = get_option('tz_email');
        if (!isset($emailTo) || ($emailTo == '') ){
            $emailTo = get_option('admin_email');
        }
        $subject = 'I Have A Question to Ask from '.$name;
        $thanksubject = 'Thank you for the Form Submission';
        $body = "Name: $name \n\nEmail: $email \n\nInterest $interest \n\nComments: $comments";
        $userbody = "";
        $headers = 'From: '.$name.' ' . "\r\n" . 'Reply-To: ' . $emailTo;
        //$headers .= 'Bcc: [e-mail]' . "\r\n";
        //$headers .= 'Bcc: [e-mail]' . "\r\n";

        wp_mail($emailTo, $subject, $body, $headers);
        wp_mail($email,$thanksubject, $body, $headers);
        $emailSent = true;

This is after writing to csv. it would be sent if there is no error such as blank fields. $interest only register one array, for example if I select all checkboxes, it would show all in email. So far I tested and it only show one last checkbox. Do you know where I went wrong?

UPDATED

I have figured it out and managed to write the checkboxes’ values to csv and emails as well.

Answer 1

This would work , its accepts array and converts it to CSV automatically

    $csvData = array($name,$email,$comment);
    $filename='I-have-question.csv';
    $isNew = (file_exists($filename) || is_file($filename)) ? false : true ;
    touch($filename); //Sets access and modification time of file and  If the file does not exist, Create it.
    $fp = fopen($filename, 'w');
    if($isNew) //Add header Information if its new 
    {
        fputcsv($fp , array ('NAME', 'EMAIL', 'COMMENT'));
    }
    fputcsv($fp, $csvData);
    fclose($fp);


    //To Force CSV downlaod  
    header("Content-type: application/csv");
    header("Content-Disposition: attachment; filename=file.csv");
    header("Pragma: no-cache");
    header("Expires: 0");
    readfile($filename);

A new concept to always force header information even if it does not exist before

        $csvData = array($name,$email,$comment);
        $filename='I-have-question.csv';
        $isNew = (file_exists($filename) || is_file($filename)) ? false : true ;
        touch($filename); //Sets access and modification time of file and  If the file does not exist, Create it.
        $fp = fopen($filename, 'a');
        forceHeader(array ('NAME', 'EMAIL', 'COMMENT'),$filename);
        fputcsv($fp, $csvData);
        fclose($fp);




        function forceHeader(Array $headerParam,$csvFile)
        {
            $headerParam = implode(",", $headerParam);
            $fileHeader = file_get_contents($csvFile, NULL, NULL, 0, strlen($headerParam));
            if($headerParam != $fileHeader)
            {
                $content = $headerParam ."\r\n" ;
                $content .= file_get_contents($csvFile, NULL, NULL, strlen($headerParam) + 2);
                file_put_contents($csvFile,$content);
            }

        }

==== Interest =====

$interest = isset($_POST[$interest]) ? implode("; " , $_POST[$interest]) : array();
$csvData = array($name,$email,$comment,$interest);

Thanks
