Jinsi ya Kutengeneza Soft Delete System kwa Records (Rahisi & Professional

Jifunze kutengeneza Soft Delete System kwa PHP & MySQL—badala ya kufuta data kabisa, inawekwa kwenye status ya deleted ili iweze kurejeshwa baadaye.

✅ 1. Ongeza Column kwenye Database

Ongeza field kwenye table yako:

ALTER TABLE posts ADD deleted_at DATETIME NULL;

Hii ndiyo itahifadhi tarehe ya kufutwa (soft delete).

✅ 2. Soft Delete Function (Badala ya DELETE)
function soft_delete($id, $conn) {
$sql = "UPDATE posts SET deleted_at = NOW() WHERE id = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("i", $id);
return $stmt->execute();
}

Kutumia:

soft_delete(5, $conn);

✅ 3. Ku-Filter Records Zisizo Futwa

Badala ya:

SELECT * FROM posts;

Tumia:

SELECT * FROM posts WHERE deleted_at IS NULL;

✅ 4. Kuonyesha Items Zilizofutwa (Recycle Bin)
SELECT * FROM posts WHERE deleted_at IS NOT NULL;

✅ 5. Restore (Undo Delete)
function restore_record($id, $conn) {
$sql = "UPDATE posts SET deleted_at = NULL WHERE id = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("i", $id);
return $stmt->execute();
}

Kutumia:

restore_record(5, $conn);

✅ 6. Permanent Delete (Optional)

Ikiwa unataka kufuta kabisa:

function permanent_delete($id, $conn) {
$sql = "DELETE FROM posts WHERE id = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("i", $id);
return $stmt->execute();
}
