How do store 3 radio button lists in mysql database in single column, different rows?

问题

This is my ratings.php (html codes)

<input type="radio" name="selectThree" value="1">
<input type="radio" name="selectThree" value="2">
<input type="radio" name="selectThree" value="3">
<input type="radio" name="selectThree" value="4">
<input type="radio" name="selectThree" value="5">

<input type="radio" name="selectTwo" value="1">
<input type="radio" name="selectTwo" value="2">
<input type="radio" name="selectTwo" value="3">
<input type="radio" name="selectTwo" value="4">
<input type="radio" name="selectTwo" value="5">

<input type="radio" name="selectOne" value="1">
<input type="radio" name="selectOne" value="2">
<input type="radio" name="selectOne" value="3">
<input type="radio" name="selectOne" value="4">
<input type="radio" name="selectOne" value="5">

So when users select the value, it will generate the below codes here to insert into database:

<?php
include_once "mysqli.connect.php";
include_once "config.php";

if(isset($_POST['Click']))      
{

$rating = explode($_POST['selectOne'], $_POST['selectTwo'], $_POST['selectThree']);
$_SESSION['commentInput'] = array();
$_SESSION['commentInput'][] = $_POST['comment'][0];
$_SESSION['commentInput'][] = $_POST['comment'][1];
$_SESSION['commentInput'][] = $_POST['comment'][2];

if(isset($_REQUEST["comment"]))
{

$merge = array_combine ($_SESSION['product'],$_SESSION['commentInput']);
foreach($merge as $key => $value)
{

$sqlComment = "INSERT into comment (comment, product) VALUES ('".$value."', '".$key."')";
$result = $mysqli->query($sqlComment);
}

echo"<script type='text/javascript'>alert('Thank you for your comment!' )</script>";
}

else
{

echo "<script type='text/javascript'>alert('Please comment!')</script>";    
}   

}

I want to store like this in mysql database ->

product|rating
--------------
shirt  | 2
pants  | 3
dress  | 5

But now it stores like this:

product|rating
--------------
shirt  | Array
pants  | Array
dress  | Array

after I used this ->

$rating = explode($_POST['selectOne'], $_POST['selectTwo'], $_POST['selectThree']);

//mysql
$sqlRating = "INSERT into ratings (product, rating) VALUES ('".$key."', '".$rating."')";
$result = $mysqli->query($sqlRating);

How do I make the values store into mysql? Please help thanks!

回答1:

your $rating is an array

you should stor values like that $rating[0] or $rating[1] or $rating[2] , so to store them like that u can manage them in php wich button is selected or clicked then store them in your table

回答2:

Put them in a comma-separated way using implode:

$rating = explode($_POST['selectOne'], $_POST['selectTwo'], $_POST['selectThree']);

//mysql
$sqlRating = "INSERT into ratings (product, rating) VALUES ('".$key."', '".implode(",",$rating)."')";
$result = $mysqli->query($sqlRating);

Later on you should be able to use find_in_set to look into that column while filtering data.

回答3:

try putting it inside a foreach loop something like this.

// create an array here that contains the key and the rating key=>rating and save it to $ratings array.

foreach($ratings as $key=>$rating){

   //mysql
   $sqlRating = "INSERT into ratings (product, rating) VALUES ('".$key."', '".$rating."')";
   $result = $mysqli->query($sqlRating);
}

by the way, here's tutorial on posting radion buttons values http://www.homeandlearn.co.uk/php/php4p10.html

Update: Assuming that $key contains array of products. (ex. array('shirt', 'pants', 'jacket') and it is mapped to the values of the radio buttons.

'shirt' => $_POST['selectOne'];
'pants' => $_POST['selectTwo'];
'jacket' => $_POST['selectThree'];

We can create an array called $prod_ratings for $key and $ratings

$ratings = array($_POST['selectOne'], $_POST['selectTwo'], $_POST['selectThree']);
$prod_ratings = array_combine($key, $ratings);

Then insert the values of the array to the database by:

foreach($prod_ratings as $key=>$rating){

   //mysql
   $sqlRating = "INSERT into ratings (product, rating) VALUES ('".$key."', '".$rating."')";
   $result = $mysqli->query($sqlRating);
}
