I've searched around this site for an answer but couldnt find any.
I have a form and I'd like to get the contents of the input written into a txt file. To make it simple I just wrote a simple form and a script but it keeps getting me a blank page. Here is what I got
<html>
<head>
<title></title>
</head>
<body>
<form>
<form action="myprocessingscript.php" method="post">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
<a href='data.txt'>Text file</a>
</body>
and here is my PHP file
<?php
$txt = "data.txt";
$fh = fopen($txt, 'w+');
if (isset($_POST['field1']) && isset($_POST['field2'])) { // check if both fields are set
$txt=$_POST['field1'].' - '.$_POST['field2'];
file_put_contents('data.txt',$txt."\n",FILE_APPEND); // log to data.txt
exit();
}
fwrite($fh,$txt); // Write information to the file
fclose($fh); // Close the file
?>
This question is related to
php
Your form should look like this :
<form action="myprocessingscript.php" method="POST">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
and the PHP
<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
$data = $_POST['field1'] . '-' . $_POST['field2'] . "\r\n";
$ret = file_put_contents('/tmp/mydata.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "$ret bytes written to file";
}
}
else {
die('no post data to process');
}
I wrote to /tmp/mydata.txt because this way I know exactly where it is. using data.txt writes to that file in the current working directory which I know nothing of in your example.
file_put_contents opens, writes and closes files for you. Don't mess with it.
Further reading: file_put_contents
A possible solution:
<?php
$txt = "data.txt";
if (isset($_POST['field1']) && isset($_POST['field2'])) { // check if both fields are set
$fh = fopen($txt, 'a');
$txt=$_POST['field1'].' - '.$_POST['field2'];
fwrite($fh,$txt); // Write information to the file
fclose($fh); // Close the file
}
?>
You were closing the script before close de file.
If you use file_put_contents you don't need to do a fopen -> fwrite -> fclose, the file_put_contents does all that for you. You should also check if the webserver has write rights in the directory where you are trying to write your "data.txt" file.
Depending on your PHP version (if it's old) you might not have the file_get/put_contents functions. Check your webserver log to see if any error appeared when you executed the script.
use fwrite() instead of file_put_contents()
The problems you have are because of the extra <form> you have, that your data goes in GET method, and you are accessing the data in PHP using POST.
<body>
<!--<form>-->
<form action="myprocessingscript.php" method="POST">
