So in the start of my file i am get the Id of my product, so i can differ between products and store data correctly. Thats my php:
<?php
if(isset($_GET['dish_did']))
{
//get food id
$dish_did = $_GET['dish_did'];
//get data
$sql = "SELECT * FROM dish WHERE did=$dish_did";
//execute
$res = mysqli_query($link, $sql);
//count rows
$count = mysqli_num_rows($res);
//check whether the data is available or not
if($count==1)
{
//we have data
//get from database
$row = mysqli_fetch_assoc($res);
$nom = $row['nom'];
$description = $row['description'];
$last_rating = $row['last_rating'];
}
else{
//not availible
header("location: error.php");
}
}
else{
header("location: rate.php");
}
?>
After some HTML i have the following POST. I use this to save the data entered by the user in an other table (different table than dish).
<?php
//check whether submit clicked
if(isset($_POST['submit']))
{
//get all details
$dish_id = $_POST['dish.did'];
$review_date = date("Y-m-d h:i:sa"); //Rating Date
$user_review = $_POST['RatingLong'];
//save in database
//Create SQL to save data
$sql2 = "INSERT INTO review SET
user_review = '$user_review',
review_date = '$review_date',
dish_id = '$dish_id'
";
//Execute the Query
$res2 = mysqli_query($link, $sql2);
//check wether query executed successfully or not
if($res2==true)
{
//Query Executed and Review Saved
$_SESSION['review'] = "<div class='success'>Review Successfull.</div>";
// header('location:'.SITEURL);
}
else{
//Failed to save review
$_SESSION['review'] = "<div class='success'>Error.</div>";
// header('location:'.SITEURL.'about.php');
}
}
?>
Without the dish_id i am able to store data, but they aren´t assigned (so useless).
I am not sure how i can link the id correct, to be saved. I have seperate links for every product by id: http://localhost/Project/index.php?dish_did=2 for example.
What i have to change, that user_review and review_date is stored correctly with the same dish_id (table review) as dish_did (table dish).
ADDITIONAL QUESTION:
how can i comment ?
edit:
added rate.php code and database
<?php
$sql = "SELECT * FROM dish WHERE hide ='1'";
$res = mysqli_query($link, $sql);
$count = mysqli_num_rows($res);
if($count>0)
{
echo'<div >';
while($row=mysqli_fetch_assoc($res))
{
$did = $row['did'];
$nom = $row['nom'];
$description = $row['description'];
$last_rating = $row['last_rating'];
?>
<div ></div>
<!-- <div > -->
<div >
<div >
<a href="index.php">
<img src="img/gallery/01.jpg" >
</a>
<h4 ><?php echo $nom; ?></h4>
<p ><?php echo $description; ?></p>
<a href="<?php echo SITEURL; ?>index.php?dish_did=<?php echo $did; ?>" role="button">Jetzt Bewerten!</a>
<!-- </div> -->
</div>
</div>
<?php
}
}
else{
echo "<div class='error'>Food not available.</div>";
}
?>
Here my database:
create table users
(
uid int primary key AUTO_INCREMENT,
username varchar(25),
password varchar(25),
created_at date,
score int
);
create table dish
(
did int primary key AUTO_INCREMENT,
nom varchar(25),
description varchar(250),
last_rating int,
hide int DEFAULT 0 NOT NULL
);
create table review
(
review_id int primary key AUTO_INCREMENT,
user_id int ,
dish_id int ,
user_rating int ,
user_reveiw varchar(100),
review_date datetime,
foreign key (user_id) references users(uid),
foreign key (dish_id) references dish(did)
);
CodePudding user response：
I found the issue. It has to be this GET:
$dish_did = $_GET['dish_did'];
And this is the correct sql Statement:
$sql2 = "INSERT INTO review SET
dish_id = '$dish_did',
user_review = '$user_review',
review_date = '$review_date'
";
In summary, I was in trouble because of my designations. I took the wrong ID, it must be $dish_did
CodePudding user response：
You can easily pass the id via url where you redirect your user to rate.php then use GET method to get the id in the rate.php file. Here is your solution:
<?php
if (isset($_GET['dish_did'])) {
//get food id
$dish_did = $_GET['dish_did'];
//get data
$sql = "SELECT * FROM dish WHERE did=$dish_did";
//execute
$res = mysqli_query($link, $sql);
//count rows
$count = mysqli_num_rows($res);
//check whether the data is available or not
if ($count == 1) {
//we have data
//get from database
$row = mysqli_fetch_assoc($res);
$nom = $row['nom'];
$description = $row['description'];
$last_rating = $row['last_rating'];
} else {
//not availible
header("location: error.php");
}
} else {
//ADDED dish_did in rate.php
header("location: rate.php?id=$dish_did");
} ?>
And here is your rate.php
<?php
//check whether submit clicked
//GETTING THE ID FROM THE URL
if(isset($_POST['submit']) && isset($_GET['id'])) {
//get all details
//ASSIGNING THE ID FROM URL USING GET
$dish_id = $_GET['id'];
$review_date = date("Y-m-d h:i:sa"); //Rating Date
$user_review = $_POST['RatingLong'];
//save in database
//Create SQL to save data
$sql2 = "INSERT INTO review SET
user_review = '$user_review',
review_date = '$review_date',
dish_id = '$dish_id'
";
//Execute the Query
$res2 = mysqli_query($link, $sql2);
//check wether query executed successfully or not
if ($res2 == true) {
//Query Executed and Review Saved
$_SESSION['review'] = "<div class='success'>Review Successfull.</div>";
// header('location:'.SITEURL);
} else {
//Failed to save review
$_SESSION['review'] = "<div class='success'>Error.</div>";
// header('location:'.SITEURL.'about.php');
}
} ?>
