Querying 3 mysql tables to create an HTML table - php

Question

Goal
I'm trying to draw up a restaurant menu in HTML using MySQL queries.
MySQL Tables

Current outcome
+--------------------------------------+
| Pâtes |
+--------------------------------------+
| | 1 | 2 |
+--------------------------------------+
| spaghetti | 8.75 | 11.75 |
| lasagne | 9.95 | 13.25 |
+--------------------------------------+
+--------------------------------------+
| Ailes de poulet |
+--------------------------------------+
| | 3 | 4 | 5 |
+--------------------------------------+
| Régulières | 0.95 | 9.50 | 11.95 |
| Piquantes | 0.95 | 9.50 | 11.95 |
+--------------------------------------+
Current code
function catalogue_complet($mysqli) {
$categories = mysqli_query($mysqli, "SELECT * FROM categories ORDER BY nom_categorie ASC");
$produits = mysqli_query($mysqli, "SELECT * FROM produits ORDER BY id, prix ASC");
$dimensions = mysqli_query($mysqli, "SELECT * FROM dimensions");
while($categorie = mysqli_fetch_array($categories))
{
echo "<h2>".$categorie[1]."</h2>";
echo "<table class='catalogue'>";
if(!empty($categorie[2]))
{
echo "<tr>";
echo "<th> </th>";
$array_categorie = explode("-",$categorie[2]);
foreach($array_categorie as $categorie)
{
echo "<th>".$categorie."</th>";
}
echo "</tr>";
}
while($produit = mysqli_fetch_array($produits))
{
if($categorie[0] == $produit[2])
{
echo "<tr>";
echo "<td>".$produit[1]."</td>";
$array_prix = explode(",",$produit[2]);
foreach($array_prix as $prix)
{
echo "<td class='prix'>".$prix."</td>";
}
echo "</tr>";
}
}
echo "</table>";
}
}
Other details
I may have a few errors slipped in with keys (example: $produit[2]) as I've simplified the tables, but I do have the proper information in my output. As I've mentioned above, my problem lies in the fact that I get the dimension ID as entered in my table repas. I can't figure out how to get the proper information (Ailes de poulet and Pâtes) to show up ?

Answer 1

I think you basically need to get the column names of your tables correctly.
In your current code, you are not using the dimensions table at all, although you have queried it.
Keep the names of all dimensions in an array, and refer them whenever the id is known.
Storing the dimensions in an array.
$dimensions = mysqli_query($mysqli, "SELECT * FROM dimensions");
$dim_arr = Array();
if($dimensions){
while($d = $mysqli_fetch_assoc($dimensions)){
$dim_arr[$d['id']] = $d['dimension'];
}
}else{
die(mysqli_error($mysqli));
}
Using them inside the foreach loop.
foreach($array_categorie as $categorie)
{
//Perform error checking here - if(isset($dim_arr[$categorie]))
$dim_name = $dim_arr[$categorie];
echo "<th>".$dim_name."</th>";
}
This should display the headings.

Answer 2

Ok, so I've found a working solution. Please excuse the length of the code, and as mentioned in the original post, some differences may occur when looking at the tables in the question, but it is simplified to focus on the desired effect.
Bottom line, the code below produces the table with title (ex: Pâtes), and each product and price line (ex: Lasagne | 9,95 | 13,25)
function catalogue_complet($mysqli) {
$categories = mysqli_query($mysqli, "SELECT * FROM catalogue_categories ORDER BY nom_categorie ASC");
$produits = mysqli_query($mysqli, "SELECT * FROM produits ORDER BY id, prix ASC");
$dimensions = mysqli_query($mysqli, "SELECT * FROM dimensions");
while($categorie = mysqli_fetch_array($categories))
{
echo "<h2>".$categorie[1]."</h2>";
echo "<table class='catalogue'>";
mysqli_data_seek($produits, 0);
if(empty($produits))
{
echo "<tr><td>".AUCUN_PRODUIT."</td></tr>";
}
else
{
while($produit = mysqli_fetch_array($produits))
{
// Dimensions -----------------------------------------------------------
if(!empty($categorie[3]))
{
echo "<tr>";
while($dimension = mysqli_fetch_array($dimensions))
{
$array_dimensions = explode("-",$categorie[3]);
foreach($array_dimensions as $dim)
{
if($dim == $dimension[0])
{
if($i == 0)
{
echo "<th> </th>";
}
echo "<th>".$dimension[1]."</th>";
$i++;
}
}
}
echo "</tr>";
}
// Produits -------------------------------------------------------------
if($categorie[0] == $produit[4])
{
echo "<tr>";
echo "<td>".$produit[1]."</td>";
$array_prix = explode(",",$produit[3]);
foreach($array_prix as $prix)
{
if( empty($prix) or ($prix == "0"))
{
echo "<td> </td>";
}
else
{
echo "<td class='prix'>".str_replace(".",",",$prix)." $</td>";
}
}
echo "</tr>";
}
}
}
echo "</table>";
}
}
