drop down menu showing old records from the database
im doing this project, they is a page called insert a review, in my insert review page , before you can write a review you select the title of the book, i use a drop down menu for this, so the user writes a review on an existing book in my books database,
but now the issue is, my drop down menu is showing old records, book's title that i have deleted. and when i display my books table, the old records don't show, which is correct.
i just want to know why is my drop down menu showing old deleted records?

<?php
echo "<select name='title' >";
$res=mysql_query("SELECT * FROM mbooks");
while($entry=mysql_fetch_array($res))
{
echo "<option";
if($entry['title'] ==fred)
{
echo " selected=selected";
}
echo ">" .$entry['title']. "</option>";
}
echo "</select>";
?>

We would need to see your CREATE TABLE statements and your test data model. We might need to see the other processes that led to the current state of the test data model. In other words, it's not a question with any one answer. It's a research project.

Since you will have to convert the data base extension from MySQL to something else, you might as well learn the right way now, and never go back to MySQL.

Line 9 of the code snippet is almost certainly wrong, unless you have a defined constant somewhere else named "fred." You might want to read this article, paying particular attention the part about time bombs.

what do you mean by "deprecated in PHP" is they a new way to do a drop down menu?
my connect seems alright, because my other drop downs are working fine.

Database records aren't cached, so you need to double check you're using the correct connection to the correct database, and using the correct table. Do you have the database on a development and a live server - make sure you select the right one.
Other than that, we're working blind here - nothing wrong with your code (apart from mySQL library being deprecated in PHP, but that won't affect the records!)
