When posting code, please enclose it in the forum's

It is also helpful to post the error messages exactly as they appear.

thats the problem.... am not sure which one is generating the error

 

 

but i know that before i started workin on the UPDATE syntax, the error wasnt there

 

so lets start with the UPDATE

 

 $sql_news_query = "UPDATE `news` SET
                              `news`.`id` = '{$id}',    
                              `news`.`news_title` = '{$topic}', 
                                `news`.`new_content` = '{$body}', 
                                WHERE `news`.`id` = {$id}";

 

and as u can see... i have tried several update...

 

i commented out....pls take it step by step

 

i need a solution

mysql version is 5.1.38

Then you need to insert some echos to tell you which query is failing. Wherever you use die(mysql_error()), also echo the query string, not only so you can tell which query is failing, but so you can examine the query to make sure it contains what you would expect it to contain.
