PHP MYSQL KEYWORD SEARCH HELP

Report · Aug 22, 2011

Im creating a search for a image gallery and I want it to be able to pull up an image based on the keyword assigned to the image you searched. I have 4 fields in my DB, (id,layout"or image",description,key_words). My problem is when I enter a keyword in my textfield when the results page loads all I get is the field names (id,layout,description,key_words) instead of the actually data within those fields.

I believe my problem lies within this line of code:

$query_Recordset1 = sprintf("SELECT * FROM images2 WHERE key_words = %s ORDER BY id DESC", GetSQLValueString($colname_Recordset1, "text"));

this code displays my DB field names, but not the data I inserted in those fields.

So I tried changing the code to this:

$query_Recordset1 = sprintf("SELECT * FROM images2 WHERE key_words LIKE '%$keyword%' ORDER BY id DESC", GetSQLValueString($colname_Recordset1, "text"));

This code did display my mysql data, but not the data I entered in my textfield. With this code I don't even have to enter any keywords in the text field, I can simply click the search button and my mysql data would show up, even though I didn't enter a keyword...?

Im very confused I've been working on this off and on for about a month now and have been in 3 different forums and know one seems to be able to help. It would greatly appreciated if someone could help me through this.

Here is all my code for a better understanding:

$query_Recordset1 = sprintf("SELECT * FROM images2 WHERE key_words LIKE 
 '%$keyword%' ORDER BY id DESC", GetSQLValueString($colname_Recordset1, 
 "text"));

Why are you using the $keyword variable rather than the sprintf parameter? I don't know php, but it seems like that is your problem. Maybe try something like this:

$query_Recordset1 = sprintf("SELECT * FROM images2 WHERE key_words LIKE %s ORDER BY id DESC", GetSQLValueString("%" . $colname_Recordset1 . "%", "text"));

I appreiciate your input but that didn't work either.

Your textfield is named 'keyword', but you are trying to populate a variable from a form field called 'key_words'. Change one or the other.
