Update image with information in php - php

Question

I've been looking for a code to update my image from the database from youtube and here in stackoverflow. But I cant seem to make it work. The image can get updated but the title and the body cannot be edited. please help.
im usig it with php and phpmyadmin
this is the code i've been trying to make the update:
if (isset($_POST['update'])) {
$id = $_POST['editid'];
$edtitle = $_POST['edittitle'];
$edbody = $_POST['editmyTextarea'];
$file = $_FILES['editpgupload'];
$filename = $file['name'];
$fileTmp = $file['tmp_name'];
$filesize = $file['size'];
$fileerror = $file['error'];
$filetype = $file['type'];
$fileExt = explode('.', $filename);
$fileActExt = strtolower(end($fileExt));
$allowed = array('jpg', 'jpeg', 'png');
if (in_array($fileActExt, $allowed)) {
if ($fileerror === 0) {
if ($filesize < 1000000) {
$filenamenew = uniqid('', true).".".$fileActExt;
$fileds = '../../../image/upload/'.$filenamenew;
move_uploaded_file($fileTmp, $fileds);
$sql = "UPDATE patients_guide SET pg_title = '$edtitle', pg_body = '$edbody', pg_image = '$filenamenew' WHERE pg_id = '$id'";
mysqli_query($conn, $sql);
header("Location: ../index.php?update=success");
}else{
// echo "your image is too large";
header("Location: ../index.php?error=imagetoolarge");
}
}else{
// echo "There was an error uploading your file";
header("Location: ../index.php?error=errorupload");
}
}else{
// echo "You can not upload this file";
header("Location: ../index.php?error=cannotupload");
}
}
it only updates the image but the title and the body stay the same. it cannot be edited. this should be able to update the title, body and the image.
patients_guide structure
CREATE TABLE `patients_guide` (
`pg_id` int(11) NOT NULL AUTO_INCREMENT,
`pg_title` varchar(100) NOT NULL,
`pg_body` text NOT NULL,
`pg_image` varchar(100) NOT NULL,
PRIMARY KEY (`pg_id`)
) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf

I got it.
For someone that has the same problem as me here is the code:
if (isset($_POST['update'])) {
$id = $_POST['editid'];
$edtitle = $_POST['edittitle'];
$edbody = $_POST['editmyTextarea'];
$file = $_FILES['editpgupload'];
$filename = $file['name'];
$fileTmp = $file['tmp_name'];
$filesize = $file['size'];
$fileerror = $file['error'];
$filetype = $file['type'];
//remove old image
unlink('../../../image/upload/'.$row['pg_image']);
$fileExt = explode('.', $filename);
$fileActExt = strtolower(end($fileExt));
$allowed = array('jpg', 'jpeg', 'png');
if (in_array($fileActExt, $allowed)) {
if ($fileerror === 0) {
if ($filesize < 1000000) {
$filenamenew = uniqid('', true).".".$fileActExt;
$fileds = '../../../image/upload/'.$filenamenew;
move_uploaded_file($fileTmp, $fileds);
$sql = "UPDATE patients_guide SET pg_title = '$edtitle', pg_body = '$edbody', pg_image = '$filenamenew' WHERE pg_id = '$id'";
mysqli_query($conn, $sql);
header("Location: ../index.php?update=success");
}else{
// echo "your image is too large";
header("Location: ../index.php?error=imagetoolarge");
}
}else{
// echo "There was an error uploading your file";
header("Location: ../index.php?error=errorupload");
}
}else{
$sql = "UPDATE patients_guide SET pg_title = '$edtitle', pg_body = '$edbody' WHERE pg_id = '$id'";
mysqli_query($conn, $sql);
header("Location: ../index.php?update=success");
}
}
