write to file

tiny · #1 (**permalink**) 01-11-04, 10:22 PM

I am ok with php but the script I need seems out of my league. I need a script that lets a user enter a name in a Text box and then hits Submit. Upon doing this I need the data he/she entered to write to a simple prewritten .txt file and launch a cgi program.

Here is the best example I can give.
1. user enters name (tiny)
2. hits submit
3. Name(tiny) is writen to the .txt file like this /name:tiny

4. cgi program is launched.

Example of prewrittem txt file.

<---start--->
Text jjjjjjjjj
Text lllllllll
Text jjjjjjjj
Text iiiiiiiiiii /sample /name:tiny (<-----written from script)
<---end--->

The cgi program actually reads this text file and needs it to launch the program.

Hope you all can Help

Thanks,
Tiny

Here you go:

// --------------- Code for page1.html -----------------------------------

Code:

<html><head><title>Page 1</title></head><body>
<form action="page2.php" method="post">
<table border="0" cellpadding="0" cellspacing="2">
<tr>
<td>
<p><b><font size="2">Name:</font></b></p>
</td>
<td><input type="text" name="from" size="20"></td>
</tr>
<tr>
<td></td>
<td>
<div align="right">
<input type="submit" name="ok" value="Send"></div>
</td>
</tr>
</table>
</form>
</body></html>

// --------------- Code for page2.php -----------------------------------

PHP Code:


			
<?php
echo "<html><head><title>Page 1</title></head><body>";
$name = $_POST['name'];
echo "$name will be added to record on ";
echo $date;
echo "<br><br>";
$outputstring = "/sample/name:$name\n";
@ $fp = fopen("file.txt", "a");
flock($fp, 2); 
if (!$fp)
{
    echo "<p><strong> Your Addition could not be processed at this time.
         Please try again in a few minutes.</strong></p></body></html>";
    exit;
} 
fwrite($fp, $outputstring);
flock($fp, 3); 
fclose($fp);
echo "<center><p><b><a href=\"page3.php\">Click Here to continue</a></b></p></center>"; 
}
 
?>

// --------------- Code for page3.php -----------------------------------

PHP Code:


			
<?php
$URL=http://yourdomain.com/cgi_file.cgi;
header ("Location: $URL");
?>
<html>
<title>Launching CGI File</title>
<head></head>
<body>
</body>
</html>

That should do it. Of course you can combine all 3 of these page into one. I hope this helps you out.

ok I went ahead and installed the script. I am probably doing something wrong, but I am getting a parse error.

Parse Error page2.php on line 20
Of course I have edited the script to reflect my page info.

Thanks,
Tiny

Create the file "file.txt" in that same directory and CHMOD it to 777 (give the file read, write and execute permission. Also there is an extra "}" at the end of page2.php that shouldn't be there (right before "?>") take that out as well.

Also, post your modified version of the code so we can look at it.

Ok the page2.php works great now. It adds the needed line to the .txt file, however it adds it like this:

/sample /name:

The name I enter "tiny" does not appear.

should be like this

/sample /name:tiny

removing the } in page2.php was the ticket

Also I now am getting a parse error when clicking the "Click Here to continue" here is the error.

Parse error: parse error in /page3.php on line 2

The only thing I edited in the code was the url to reflect mine. All else remained the same.

Thank You so much for working with me on this.

Oops.... it's because I named the field in the first page wrong. Try this for page 1:

Code:

<html><head><title>Page 1</title></head><body>
<form action="page2.php" method="post">
<table border="0" cellpadding="0" cellspacing="2">
<tr>
<td>
<p><b><font size="2">Name:</font></b></p>
</td>
<td><input type="text" name="name" size="20"></td>
</tr>
<tr>
<td></td>
<td>
<div align="right">
<input type="submit" name="ok" value="Send"></div>
</td>
</tr>
</table>
</form>
</body></html>

The only thing I change in page 1 was the following line:

Code:

<td><input type="text" name="name" size="20"></td>

Oh, and change page 3 to the following:

Code:

<?php
$URL="http://yourdomain.com/cgi_file.cgi";
header ("Location: $URL");
?>
<html>
<title>Launching CGI File</title>
<head></head>
<body>
</body>
</html>

In other words, add quotes around the link you want to go to:

Code:

$URL=http://yourpage.com/cgi_file.cgi;

Absolutely Beautiful. I should have found the quotations error. I appologize.

Real quick, would it be hard or even possible for the field we are adding to be erased or better yet overwritten each time instead of new lines?

Thanks a million

Well, it depends. When you are saving the information to the text file, you can either append it (which means it will just add your text to the end of any previous content you had in that text file), or you can open it for write (which would mean any previous content in the file would be deleted before writing new content to it).

All you would have to change is to change the "a" to "w" in the following line:

Code:

@ $fp = fopen("list.txt", "w");

Does that answer your question?
