Delete File using dynamic values

This is the generated code that isn't working. I have had success with deleting files before, but this one I don't understand. This code comes right after my defined recordsets.


<?php
$WA_DeleteFileResult1 = false;
if(isset($_POST["deleteTreat_x"])){
$WA_DeleteFileResult1 = WA_FileAssist_DeleteFile("../img/".$_SESSION['UserID'] ."/".$_SESSION['pawsid'] ."/treat/", "".$row_treatRS['TreatImage'] ."");
}
?>

I looked at my older code that worked and adjusted it to look like this, but it still doesn't work.

<?php
if(isset($_POST["deleteTreat_x"])){
$WA_DeleteFileResult1 = false;
$WA_DeleteFileResult1 = WA_FileAssist_DeleteFile("../img/".$_SESSION['UserID'] ."/".$_SESSION['pawsid'] ."/treat/", "".$row_treatRS['TreatImage'] ."");
}
?>

It looks like the delete is not working correctly because the file is not being referenced correctly. Currently you are deleting the file that is in this value:

$row_treatRS['TreatImage']

This value comes from your treatsRS recordset. The problem is that this recordset is filtered on the $_POST['treatid'] and you do not have a form element with this name and value in your form. You do have a form element that looks like it would be holding this value, it is called tid.

If the tid field in your form is being populated with the correct treatid value then you could probably just update the form elements name to match the one you are filtering on. So you would update the tid form filed and rename it to treatid.

Thanks for the quick reply, I made the change and it works. :)

But, now I'm confused. Because I created the treatRS (recordset) on this page with a parameter passed from another page.

<form action="Delete_Treat_Item.php" method="post">
<input type="hidden" id="treatid" name="treatid" value="<?php echo $row_treatRS['TreatId']; ?>" />
<input type="image" hspace="5px" vspace="0px" border="0" align="top" src="../../img/s_delete.png" alt="delete treat" id="delete treat" />
</form>

The recordset seemed to output the correct information on the next page, but I don't understand why it didn't for the delete action. I'm guessing when I load the page up, it loads the recordset correctly, but on submit (new post) it was empty? I may have answered my own question.

Thanks

You are exactly correct, when you first see this page the correct value is posted from the previous page. The reason it broke was because you were posting the same value but with a different name. Updating the name of the element made it match like on your other page.
