select a category by name instead of id
 
currently I am using the following code to show the news for an entry in vbdynamics. I currently have to enter the category id into a custom field on the entry to get it to work. The title of the entry will be the exact same as the title of the category and I am looking to knock out a stop. Here is my code. I will have to change $entry['field97'] to $entry['title'] The area betweeen the comment is where I need to make the changes, I think.
PHP Code:

ob_start();  

// Set Your Section ID Here 
global $entry
$section1 '242'
$category1 $entry['field97']; 
// Set The Number of Articles To Display 
$limit1 '9'

if(
$category1 == '')  

echo 
"<span style='margin-left:8px;'>There is no news for this recruit</span>"

else 

$articlegrab1 vB::$db->query_read(
SELECT "
.TABLE_PREFIX."cms_nodeinfo.nodeid 
     , "
.TABLE_PREFIX."cms_nodeinfo.title 
     , "
.TABLE_PREFIX."cms_article.previewimage 
     , "
.TABLE_PREFIX."cms_article.previewtext 
     , "
.TABLE_PREFIX."cms_article.pagetext 
     , "

.TABLE_PREFIX."cms_node.url 
     , "
.TABLE_PREFIX."cms_node.publishdate 
     , "
.TABLE_PREFIX."cms_category.category 
     , "
.TABLE_PREFIX."cms_category.categoryid  
    , "
.TABLE_PREFIX."cms_node.setpublish 
  FROM "
.TABLE_PREFIX."cms_node 
INNER 
  JOIN "
.TABLE_PREFIX."cms_article 
    ON "
.TABLE_PREFIX."cms_article.contentid = ".TABLE_PREFIX."cms_node.contentid

// I DONT THINK YOU HAVE TO LOOK PAST HERE
ORDER  
    BY "
.TABLE_PREFIX."cms_node.publishdate DESC LIMIT $limit1 
"
); 




while(

If I understand what you want to do, I think you would want to change the "WHERE" line to:
Code:

WHERE ".TABLE_PREFIX."cms_category.category IN ('$category1')

and since you really should use escape_string on a string in case it contains any special characters, change the line that sets $category 1 to
Code:

$category1 = vB::$db->escape_string($entry['title']);

One other thing, it looks like the original code is written to allow field97 to be a comma separated list of category ids, and with the modified code you can only have one title.

I get
Warning: mysqli_query() [function.mysqli-query]: (42000/1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Yearby) AND (cms_node.setpublish != 0) ORDER BY cms_node.publishda' at line 28 in [path]/includes/class_core.php on line 1391

The title and category are 2 works with a space and I think that is causing the issue.

Thoughts?
