I hope this isn't condescending, but you have a foreign key constraint that
is failing. I would probably echo the output of $_POST['post_store'] to see
what value, if any, is being written. If the output seems proper, I'd check
your other table and make sure that the data exists in that table. And,
finally if all of that checks out, I'd check your SQL and see if you have
appropriate data types, etc.

I hope that may help.

Subject: Insert query error
I am getting the following error trying to run the below query. Any
suggestions on what I am doing wrong?

Thank you,

Something went wrong while inserting your store visitCannot add or
update a child row: a foreign key constraint fails (`store`.`posts`,
CONSTRAINT `posts_ibfk_1` FOREIGN KEY (`post_store`) REFERENCES
`stores` (`store_id`) ON DELETE CASCADE ON UPDATE CASCADE)

$sql = "INSERT INTO
posts(market, type, post_store, post_tptest, post_content, post_by,
post_date)
VALUES('" . mysql_real_escape_string($_
POST['market']) . "',
'" . mysql_real_escape_string($_POST['type']) . "',
'" . mysql_real_escape_string($_POST['post_store']) . "',
'" . sha1($_POST['post_tptest']) . "',
'" . mysql_real_escape_string($_POST['post_content']) . "',
" . $_SESSION['user_id'] . ",
