UPDATING TEXT AREA using PHP !!

Jul 11th, 2008

Hello,
I have 1 file notex.php with both form and php scripting .
FORM IS THIS :
----------------------
[code language=html]
<form action="notesx.php" method="post">
<fieldset>
<legend>
Capítulo 01:
</legend>
<textarea id='userInput' name="textspace" value="'.$textspace.'" cols="40" rows="3" ></textarea>
<br>
<input type="submit" name="save" value='save'/>
<input type="submit" name="edit" value='edit'/>
<input type="submit" name="show" value='show'/>

<br>
<p><b id='boldStuff2'></b> </p>

</fieldset>
</form>
[/code]

and
PHP code is this :
---------------------------------
[code language=php]
<?php

if ($_POST['save'])
{
$space = $_POST['textspace'];
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");

fwrite($fh, $space);

fclose($fh);
echo "Saved";
}

if ($_POST['edit'])
{

$textspace="rajan";

}

if ($_POST['show'])
{
$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
if(filesize($myFile)!=0)
{
$theData = fread($fh, filesize($myFile));
}
else
{
echo "The file is empty";
}
fclose($fh);
echo $theData;

}

?>

[/code]

Now,this is what I want.Well,write and read is working great,but i want that when edit button is pressed the TEXTAREA is updated/filled with the file's content/data .for testing purposes I just assigned rajan to $textspace,hence if it works correct,on pressing edit button the TEXTAREA must be updated with rajan.Please help !!! I am not sure of using this syntax value="'.$textspace. in the TEXTAREA .. pLEASE GUIDE ME !! tHANKS IN ADVANCE ..

Then you need another form in the block of "edit".

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
echo "<textarea id='userInput' name=\"textspace\" cols=\"40\" rows=\"3\" >".$textspace."</textarea>";
echo "<textarea id='userInput' name=\"textspace\" cols=\"40\" rows=\"3\" >".$textspace."</textarea>";

So, when the user edits the form and clicks on submit, write the contents back to the file (or whatever!).

Edit: Btw, its [code=language] (language = php, java, c, etc) and not [code language=]

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

You should be placing the variable in between the textarea tags with a conditional:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<textarea id='userInput' name="textspace" value="" cols="40" rows="3" >
<?php
if(isset($_POST)){
echo $textspace;
}
?>
</textarea>
<textarea id='userInput' name="textspace" value="" cols="40" rows="3" >
<?php
if(isset($_POST)){
echo $textspace;
}
?>
</textarea>

and for the edit, you've just got to read the file and assign it to a variable:

 php Syntax (Toggle Plain Text) 
if ($_POST['edit']){
$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
	if(filesize($myFile)!=0)
	{
	$textspace = fread($fh, filesize($myFile));
	}
	else
	{
	$textspace= "The file is empty";
	}
	fclose($fh);
}
if ($_POST['edit']){
$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
	if(filesize($myFile)!=0)
	{
	$textspace = fread($fh, filesize($myFile));
	}
	else
	{
	$textspace= "The file is empty";
	}
	fclose($fh);
}
