Delete confirm only using PHP - php

Question

I want to delete links to delete images on an SQL database. I am tasked with creating a delete confirm option not using JavaScript just PHP.
require_once("photoalbum-common.php");
$pdo = connect();
if ( isset( $_GET['deletionid'])) {
$errorMessage = deletePhotograph( $pdo, $_GET['deletionid']);
if ( $errorMessage != "") {
print "<div class='errormessage'>$errorMessage</div>\n";
} else {
print "<div class='message'>Image deleted.</div>\n";
}
}
The code below is in "photoalbum-common.php".
<?php
function deletePhotograph( $pdo, $deletionid) {
$errorMessage = "";
// retrieve name of image file so we can delete it
$stmt = $pdo->prepare("SELECT `image` FROM `photographs` WHERE `photoid`=?");
$stmt->execute( array( $deletionid));
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
if ( count( $rows) == 1) {
// delete file
unlink( "images/".$rows[0]['image']);
// delete database record
$stmt = $pdo->prepare("DELETE FROM `photographs` WHERE `photoid`=?");
$stmt->execute( array( $deletionid));
$affected_rows = $stmt->rowCount();
} else if (count( $rows) > 1) {
$errorMessage .= "ID matches more than one record. ";
} else {
$errorMessage .= "ID not found: nothing to delete. ";
}
return $errorMessage;
}
?>

Answer 1

Use something like this. An interstitial page, that accepts a GET request:
GET Request GET /delete.php?id=123
Are you sure you wanna delete?
POST Request POST /delete.php?id=123
Execute the PDO.
You are supposed to write the code for the PHP. If the answer is not enough for this, well, here we go:
<?php
if (count($_POST)) {
// POST Request
deletePhotograph();
} else {
// GET Request
?>
<p>Are you sure you wanna delete?</p>
<!-- Empty action will POST to the same page. -->
<form action="" method="POST"><input type="submit" value="I confirm, Delete" /></form>
<?php
}
?>
