[RESOLVED] write to file?

how can i write text into a textbox and then press a button and save the text thats in the textbox to a file?

edit: i found this code:

http://www.tizag.com/phpT/filewrite.php

Code:

$myFile = "testFile.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); $stringData = "Floppy Jalopy\n"; fwrite($fh, $stringData); $stringData = "Pointy Pinto\n"; fwrite($fh, $stringData); fclose($fh);

how can i make this code save from a textbox instead of a string?
... and make the linebreaks save with a <br/> tag?

input.php

Code:

<form action="process.php" method="post"> <input type="hidden" name="submit" /> <textarea name="text_input" rows="2" cols="20"></textarea> <input type="submit" name="submit" value="Write File" /> </form>

process.php

Code:

<?php if(isset($_POST['submit'])) { $myFile = "testFile.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); $stringData = str_replace(array("\n","\r"), array("<br/>","<br/>"), $_POST['text-input']); fwrite($fh, $stringData); fclose($fh); } else { header('Location: input.php'); exit; } ?>

Right, so we have input.php, slap this code in the <body> section, you can type info into the textarea and when you hit submit it will send that POST data to the process.php script, it will check to see if the form has been submitted (you can add additional conditions if desired), then replaces the \n or \r with <br/>.

This code is not tested / written from memory, so don't expect it to work first time. Be sure to tell me how you get on.

Re: write to file?

My bad, change this:

Code:

$stringData = str_replace(array("\n","\r"), array("<br/>","<br/>"), $_POST['text-input']);

to this:

Code:

$stringData = str_replace(array("\n","\r"), array("<br/>","<br/>"), $_POST['text_input']);

Re: write to file?

you're referring to $_POST['text-input'] when saving the text with fwrite(); however, your form field is named text_input. simply change that to $_POST['text_input'].

a somewhat better way of checking for a form submission is checking the REQUEST_METHOD ($_SERVER['REQUEST_METHOD']), by the way. for a small application, it may be un-needed, however.

edit: oops, I guess you beat me to it.
