I have a list menu and depending on its value the search is done,
the gets redirected to itself by

The table name is package_mst and one of the column name is Adventure also another is status(which may be 1 or 0 - but that is not an issue)

The problem is:
when i submit search button it shows me this error

my list box coding is this:

<select name="mnusearch" id="mnusearch">
   	<option <?php if (isset($_REQUEST['mnusearch']) && $_REQUEST['mnusearch']=="") { ?> selected="selected" <?php } ?> value="" >All</option>
	<option <?php if (isset($_REQUEST['mnusearch']) && $_REQUEST['mnusearch']==" and p_adventure='Adventure'") { ?> selected="selected" <?php } ?> value=" and p_adventure='Adventure'">Adventure</option>
</select>

HTML:

when i run it on localhost , it runs perfect , but after uploading to server it shows me the above error,
Can anyone tell me why is it showing such error!!!

 

Please Help someone help

 

Can you post the mysql query?

 

Problem Solved
I apply $string=stripslashes($string); function to remove slash from the string .

@ freenet :
The Mysql query is : select * from package_mst where p_type='Domestic' and p_status=1 and p_adventure=\'Adventure\' order by p_id desc

BTW thanks for taking interest..

Regards.
