Get user input from form, write to text file using

问题:

As part of a subscriber acquisition I am looking to grab user entered data from a html form and write it to a tab delimited text file using php.The data written needs to be separated by tabs and appended below other data.

After clicking subscribe on the form I would like it to remove the form and display a small message like "thanks for subscribing" in the div.

This will be on a wordpress blog and contained within a popup.

Below are the specific details. Any help is much appreciated.

The Variables/inputs are

$Fname = $_POST["Fname"];
$email = $_POST["emailPopin"];
$leader = $_POST["radiobuttonTeamLeader"];
$industry = $_POST["industry"];
$country = $_POST["country"];
$zip = $_POST["zip"];

$leader is a two option radio button with 'yes' and 'no' as the values.

$country is a drop down with 40 or so countries.

All other values are text inputs.

I have all the basic form code done and ready except action, all I really need to know how to do is:

How to write to a tab delimited text file using php and swap out the form after submitting with a thank you message?

Thanks again for all the help.

回答1:

// the name of the file you're writing to
$myFile = "data.txt";

// opens the file for appending (file must already exist)
$fh = fopen($myFile, 'a');

// Makes a CSV list of your post data
$comma_delmited_list = implode(",", $_POST) . "\n";

// Write to the file
fwrite($fh, $comma_delmited_list);

// You're done
fclose($fh);

replace the , in the impode with \t for tabs

回答2:

Open file in append mode

$fp = fopen('./myfile.dat', "a+");

And put all your data there, tab separated. Use new line at the end.

fwrite($fp, $variable1."\t".$variable2."\t".$variable3."\r\n");

Close your file

fclose($fp);

回答3:

// format the data
$data = $Fname . "\t" . $email . "\t" . $leader ."\t" . $industry . "\t" . $country . "\t" . $zip;

// write the data to the file
file_put_contents('/path/to/your/file.txt', $data, FILE_APPEND);

// send the user to the new page
header("Location: http://path/to/your/thankyou/page.html");
exit();

By using the header() function to redirect the browser you avoid problems with the user reloading the page and resubmitting their data.

To swap out the form is relatively easy. Make sure you set the action of the form to the same page. Just wrap the form inside a "if (!isset($_POST['Fname']))" condition. Put whatever content you want to show after the form has been posted inside the "else{}" part. So, if the form is posted, the content in the "else" clause will be shown; if the form isn't posted, the content of the "if (!isset($_POST['Fname']))", which is the form itself will be shown. You don't need another file to make it work.
To write the POSTed values in a text file, just follow any of the methods other people have mentioned above.

This is the best example with fwrite() you can use only 3 parameters at most but by appending a "." you can use as much variables as you want.

if isset($_POST['submit']){
    $Fname = $_POST["Fname"];
    $email = $_POST["emailPopin"];
    $leader = $_POST["radiobuttonTeamLeader"];
    $industry = $_POST["industry"];
    $country = $_POST["country"];
    $zip = $_POST["zip"];

    $openFile = fopen("myfile.ext",'a');
        $data = "\t"."{$Fname}";
        $data .= "\t"."{$email}";
        $data .= "\t"."{$leader}";
        $data .= "\t"."{$industry}";
        $data .= "\t"."{$country}";
        $data .= "\t"."{$zip}";

    fwrite($openFile,$data);
    fclose($openFile);
}

Very very simple: Form data will be collected and stored in $var data in $var will be written to filename.txt \n will add a new line. File Append Disallows to overwrite the file

<?php
$var = $_POST['fieldname'];
file_put_contents("filename.txt", $var . "\n", FILE_APPEND);
exit();
?>
