Edit txt files with PHP

[raveneye]

hi, i want to be able to update a txt file using php script from anywhere.
This txt file basicly has the data which is referenced in a swf file.

I am sure its possible to do, but i just lack proper syntax to complete this script.

bewlow i attach the php scripts which i have been working with.

If anyone knows an easier syntex or know the reason why its not working please help me out lol

hi,

All I had to do to make it work was:

Change the path to the text file in both php files:

$fn = "/path/to/page/test.txt";
// changed to 
$fn = "test.txt"; 

and

url=edit.shtml
// to
url=form.php 

in processscript.php.

Just place all the files in the same folder, in a php enabled server, and that's it.

Yes! its working

Thank you so much for this. I am hoping you can help me again.
In my text field I have a variable named "Textfield" wich is referenced to get string values from the text file. So "Textfield=blah blah blah my text msg". I want the PHP script to load everything after the "TextField=" and when i update it update everything after "TextField=".

Is this possible too? Please help out again with the syntex..i am realy thinking about buying php for dummies this time!

I guess it's this:

<form action="processscript.php" method="post">
<textarea rows="25" cols="40" name="content">
<?
$fn = "test.txt";
// print htmlspecialchars(implode("", file($fn)));
$myText = htmlspecialchars(implode("", file($fn)));
// piece of text you want to remove
$myPiece = "Textfield=";
// make sure it's in the begining of your text
$pos = stripos ($myText, "Textfield=");
if ($pos === 0)
{
    // remove the begining so it's not displayed
    $myNewText = substr ($myText, strlen ($myPiece));
}
// show the new text (without $myPiece)
print ($myNewText);

?> 
</textarea><br>
<input type="submit" value="Change!"> 
</form>

and

<?
$fn = "test.txt";

// piece of text you want added to the text file
$myPiece = "Textfield=";
$content = stripslashes($_POST['content']);

// add $myPiece to the content
$content = $myPiece . $content;

$fp = fopen($fn,"w") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
echo "<meta http-equiv=\"refresh\" content=\"0; url=form.php\" />\n";
?>

This allows you to load a variable Textfield from the external text file.
In Flash MX or later you should use the LoadVars Class to load the variables - are you doing this?
If you are, the onLoad() method allows you to get the content of Textfield.
But all of this isn't necessary. You don't need a variable, and instead of onLoad() you can use onData, and get all the content of the text file. I.e., what you had in the first place, just text in a text file, could be read by Flash.

hey nunomira,

Thanks again for your reply.

$pos = stripos ($myText, "Textfield="); 

This line gave an error not sure why.

To answer your question, yes, i am using the LoadVars function. It works like a charm.
Here is a bit of code i am using to load the text from the textfile.

var myLoadr:LoadVars = new LoadVars();

myLoadr.onLoad = function (success) {
	if (success) {
		_level10.loadedInfo.htmlText = myLoadr.TextField;

ups, stripos is PHP5 only. Use strpos instead.

In order to see the other options at work (the one with text only in the text file, no variable name/value pair), try this instead:

code:

---

myLoadr.Data = function (txt) {

	if (success) {

		_level10.loadedInfo.htmlText = txt;

        }

}
