Query Debugging

MySQL hates me.
query:

HTML Code:

SELECT * FROM `aaron_eglast`.`egle_post` WHERE `slug`=`html` AND `category`=`HTML` LIMIT 1

Error:

Code:

MySQL said:
#1054 - Unknown column 'html' in 'where clause'

Table XML:
<aaron_eglast>

<egle_post>
<id>1</id>
<author>Aaron</author>
<last_updated>1</last_updated>
<content>*snip*</content>
<title>Html</title>
<slug>html</slug>
<meta_title>Beginner HTML Tutorial Series</meta_title>
<order>1</order>
<category>HTML</category>
<next>na</next>
<previous>na</previous>
</egle_post>
</aaron_eglast>

so... what is going on here?

You're using backticks. Use single quotes.

Code:

SELECT *
FROM `aaron_eglast`.`egle_post`
WHERE `slug`='html' AND `category`='HTML'
LIMIT 1

Mysql Still hates me:

Code:

	$query = "
		SELECT `slug` , `title`
		FROM `aaron_eglast`.`egle_post`
		WHERE `category` = 'HTML'
		ORDER BY `order` ASC";
	$query = mysql_query($query);
	$q = mysql_fetch_array($query);
			if (mysql_num_rows($q) == 0)
			throw new exception('For some reason, the other tutorials in this category could not be found.
			 They will not be displayed at the side of this page.');

The query returns properly in PHPmyAdmin, yet it throws an error on the page.

Its because the if conditional should be:

PHP Code:


			
if(!mysql_num_rows($query))
