Hi
I am very very very new to php and just learning so please forgive the “simplicity” of this question.
I have this code:
$name= $_POST [‘name’];
$data= “data.txt”;
$filehandler = fopen($data, “a+”);
fwrite($filehandler, “$name \n” );
fclose($filehandler);
which writes to a text file
$name is an email address
Now I want to be able to create a form that will delete an email address from the txt file.
Could someone please help.
Thanks
Be something like this
[php]
<?php // if nothing has been posted print to screen if(!isset($_POST['submit'])){ ?> FIND// post the data to be replaced
$old = $_POST[‘findmail’];
$new = $_POST[‘newmail’] ;
// Get a file to change
$data = ‘data.txt’;
if(file_exists($data)){
// change the content with the posted content
$content = file_get_contents($data);
file_put_contents($data, str_replace($old, $new, $content));
echo ‘file has been modified’;
}else{ echo ‘no file to wirte to’;
}
}
?>[/php]
Tested version that works.
[php]
<?php // if nothing has been posted print to screen if(!isset($_POST['submit'])&&(!isset($_POST['findmail']))&&(!isset($_POST['newmail']))){ ?> FIND[/php]
OK thank you I will try.
Thank you for your help
