Working with 2 tables PHP & MySQL - php

Question

I am working on a webpage that displays list of shops. I have 2 tables, shops and shops_sched.
+-shops-+
| id | title |
+-------------shops_sched-------------+
| id | shops_id | start_date | end_date |
Basically, the program displays the list of shops from the shops table, but if a value from shops.id is found # shops_sched.shops_id the page must output shops.title + 'coming soon'.
I understand this will be easy if I just place the date fields inside the table shops but due to programming restrictions I can't. I'm working on an existing project and I'm trying to minimize changes to existing functions. I can create new PHP functions if necessary though.
In addition, I need to get all the entries from the shops table. The Program needs to return all shops.title but for those shops whose id is found # shops_sched.shops_id, the program will have to return shops.title + "Coming Soon".

Answer 1

must output shops.title + 'coming soon'.
So do it like this:
$shops.title = "Donut-John";
echo $shops.title." coming soon";

Answer 2

To join the shops and shops_sched table
$query = SELECT `title` FROM `shops` JOIN `shops_sched` ON `shops`.`id` = `shops_sched`.`shops_id` WHERE `shops_sched`.`shop_id` = 5;
$result = mysql_query($query);
while($row = mysql_fetch_array($result) {
echo $row['title'] . 'coming soon';
}

Answer 3

Join the two tables :
SELECT shops.title
FROM shops INNER JOIN shops_sched ON shops.id = shops_sched.shops_id
The query should return only the the shops inside shops_sched
EDIT :
If I understood your question, try this :
SELECT shops.title, shops_sched.id
FROM shops LEFT JOIN shops_sched ON shops.id = shops_sched.shops_id
This will return all the titles, and the shops_sched.shops_id if shops.id = shops_sched.shops_id. In the other case, the hops_sched.shops_id will be null
Then you fetch the rows and if the second row is not null, print title + coming soon
Sample code : (Something like this)
$query = "SELECT `title`, 'shops_id' FROM `shops` LEFT JOIN `shops_sched` ON `shops`.`id` = `shops_sched`.`shops_id` WHERE `shops_sched`.`shop_id`";
$result = mysql_query($query);
while($row = mysql_fetch_array($result) {
if($row['shops_id'] != "")
{
echo $row['title'] . ' coming soon';
}
else
{
echo $row['title'];
}
}
