Question

Im using phpmyadmin for a website i’m creating and have a question about a inserting values into foreign key.

Im able to select an image table id when event col in events table is value x i.e…

$event = "Partay";

$sql = "SELECT i.ImageID
FROM images i 
INNER JOIN events e 
ON i.eventID = e.eventID
WHERE e.event ='".$event."'";

This works for selecting images to display. However when i want to insert and image inner join doesnt seem to work the same.

$sql = "INSERT INTO images i (i.image, e.event) 
INNER JOIN event e 
ON i.eventID = e.eventID
VALUES ('".$content."','".$event."')";

-Im trying to insert image into images table and a new event into event table so that this new image belongs to this new event.
-Also how would inserting work when inserting image with an existing event?

Any help would be good thank you.

Answer 1

Use two separate insert statements wrapped in a transaction.

To insert an image for an event which already exists, just use the insert statement for the image.
