Updating Text Files with PHP

I have a news script that updates a dat file through a form, enabling a web site owner to add news articles to their site.

However I would also like them to be be able to delete (and maybe edit) any articles they post. The script seems very basic...


<?

if($_POST["do"]=="addnew") {
$fp=fopen("news.dat","a");
$formatted=ereg_replace("\r\n","<br>",$_POST["news"]);
$formatted=ereg_replace("\n","<br>",$formatted);
$newsto=date("d M Y")."%~#".$_POST["title"]."%~#".$formatted." \n";
fwrite($fp,StripSlashes($newsto));
fclose($fp);
echo " News Article added successfully.";
}
?>



(the form)

<form name="form1" action="<?echo $_SERVER['PHP_SELF']?>" method=post>
<p align="left"><?echo date("d M Y");?></p>
</form>
<form name="form1" method="post" action="<?echo $_SERVER['PHP_SELF']?>">
<p align="center">Title :
<input type="text" name="title" size="35" style="border-styleutset;">
</p>
</form>
<form name="form1" action="<?echo $_SERVER['PHP_SELF']?>" method=post>
<p align="center">
<textarea name="news" rows="13" cols="39" style="border-styleutset;"></textarea>
</p>
<p align="center">
<input type="submit" name="formbutton1" value="Add News" style="border-styleutset;">
<br>
&nbsp;</p>
<input type="hidden" name="do" value="addnew">
</form>

Can someone show me how to create two new versions of this form - one for editing and one for deleting.

A simple link or image would allow you to embed the href that you need.

I notice you evaluate $_POST["do"]=="...
Try adding $_GET["delete"]==1 or something similar
from a link or image href, evaluate that first, and if true, then the user wants to use the delete function.

It shouldn't be too much harder than that.
