question

[Pouncer]

do you guys know how i can write stuff to a text file in my php area?

for e.g. to currently view my php stuff through webpage this is what i do:

http://localhost/<dir>/filename

or

http://<my-ip>/<dir>/filename

(e.g.: http://localhost/login.html)

i want to know how i can write to a file called Pyscho.txt, and then view this file on the web by, for.e.g

http://localhost/Pyscho.txt

any help would be greatly appreciated

ps: my pages and files are in the 'www' directory (this is where all php files are kept i think)

Hi,
Look at http://us2.php.net/fopen, also, check out the ' See also' links half way down the page, it will have information on how to write to the file.

Good luck

thanks ill read that but what im trying to do is someting like:

http://localhost/fwrite.php<something-here> (navigate from the web - not sure aboutt he syntax of the link? can someone give the correct one?)

and in the file fwrite.php i have to have a function for writing text to test.txt?

[{yak}]

I'm not sure I understand? Create a page called fwrite.php, and put in your code to write to whatever text file. Then to run the page, you go to: http://localhost/fwrite.php
Or did you mean like, http://localhost/fwrite.php?file=filenamehere
Or am I misunderstanding you completley?

[Pouncer]

well a freind of mine had something like:

www.his-site.org/fwrite.php?entry=blah

and it used to write the word 'blah' to the text file called 'test.txt'

which could be viewed by:

www.his-site.org/test.txt

i hope you understand me now, thanks for your replies and help.

Oh, I think I see what hes doing..
Did you put a textbox on your page and a submit button and want it to write out to a file?

[Pouncer]

yes thats bang on!!

i got a text box there and when i click the button i want it to write the contents of this text box to the file

(by the way, this textbox and button is on a vb form so im using the webBrowser component to do something like:

web.Navigate "http://localhost/fwrite.php?..whateverhere )
but what i need is how to construct the link and the fwrite.php file :ehh:

[{yak}]

Ok that helps. You're going to use $_GET['name of parameter'] to retreive the value. and then write that to the file, you can look at the link I gave you to write the file but this is an example, kinda :ehh:


$value = $_GET['txt']);

if(!isset($value))
{
// theres no value...redirect or something
}
// now do your insert code, of course you validate $value to make sure everything is what you want
// when you write to your txt file, write $value.
// your link would look like http://localhost/fwrite.php?txt=and then the value of your vb text box or whatever

[Pouncer]

thank you, that helps me, ill work on it now and post my results back!!

im getting a strange error:

im using this:

wb.Navigate "http://localhost/fwrite.php?txt=testline"

and getting an error:

Parse error: syntax error, unexpected T_IF in c:\wamp\www\fwrite.php on line 6

This is the code from the fwrite.php file:


<?php
$filename = 'test.txt';
$somecontent = $_GET['txt']

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}

// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}

echo "Success, wrote ($somecontent) to file ($filename)";

fclose($handle);

} else {
echo "The file $filename is not writable";
}
?>


do you guys see anything wrong? im trying to get the word 'testline' to write to the file!

[ninjanutz]

u need a semicolon here... $somecontent = $_GET['txt'] so it should be... $somecontent = $_GET['txt'] ;

[Pouncer]

ok thanks it works beautifully. but 1 problem..

when i do it twice, for e.g..

wb.Navigate "http://localinfo/fwrite.php?txt=text1"
wb.Navigate "http://localinfo/fwrite.php?txt=text1"

it writes it to the textfile but its like this:

text1text2

isnt it possible to get it like

text1
text2

..in the text file?

Add the newline character to the end of your string:

$somecontent = $_GET['txt'] . "\n";


Good luck

[Pouncer]

thanks for the reply but my text file is like this after i write to the file

wb.Navigate "http://localinfo/fwrite.php?txt=text1"
wb.Navigate "http://localinfo/fwrite.php?txt=text2"
wb.Navigate "http://localinfo/fwrite.php?txt=text3"



<html>
<h1>Header</h1>
text1<newlinecharhere>text2<newlinecharhere>text3
</html>

and when i view it in explorer:

http://localhost/test.txt

it shows the header fine, but the words are stil like this:

text1text2text3

[{yak}]

Did you add the "\n" onto the string? :confused:

[Pouncer]

yep:

$somecontent = $_GET['txt'] . "\n";

it works without the html tag stuff, but i want to mae it work *with* the html tags so i can have a nice heading at the top of the text file when viewed through i.e

[{yak}]

So it's html? I'm kinda lost, but if it's html, then, add a break tag:
<br>

[Pouncer]

yep works, thanks alot! ;)
