  • 0

The PHP code won’t delete item from database using “$noteid”. If I put a number in it’s place it will, but when I try using “$noteid”. It won’t do it. It does everything correct up to the point where it tries to delete.

Here’s how I get the “$noteid”:

//javascript
function viewnote(noteid) {

  window.location = "noteview.php?noteid="  + noteid;

}

//button in body
<input type="button" value="Edit" onclick="editnote('<?= $noteid ?>')" />

Here’s the code on the linked to page:

<?php

$noteid = $_REQUEST['noteid'];

if (isset($_POST['delete'])){
 mysql_query("DELETE FROM notes WHERE noteid='$noteid'");
 header ('Location: index2.php');
}
?>

<body>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" style="margin:0px; pading:0px"><input type="submit" name="delete" value="Delete"></form>
</body>

** It’s Working Now!!! **
What made it work was a hidden form field.

Here’s the code:

<?php
if (isset($_POST['delete'])){
        $nid = $_REQUEST['notenum'];
    mysql_query("DELETE FROM notes WHERE noteid='$nid'");
    header ('Location: index2.php');
}
?>

//body cody
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" style="margin:0px; pading:0px"><input type="text" name="notenum" value="<?php echo $noteid; ?>" style="display:none" /><input type="submit" name="delete" value="Delete"></form>

Thanks to everyone for your help!!! This site is my favourite site now.

    The problem you have is that $_REQUEST['noteid'] won’t be set after the form has posted. In that scenario you could add a hidden form field to store the value from the query string. You also need to look at sanitising your variable with mysql_real_escape_string and using $_GET or $_POST rather than $_REQUEST
