mysql error at line 1

doood · March 22, 2007

I'm pretty new at this, this is actually for an assignment I have to turn in. I have included the contents of my .sql file and the php query I am trying to get to display.

Write the corresponding php target script. Specifications:

* Use the input fields to query your table for matches -- for example, if the user enters values in both the name and city fields, matching table rows would match both values entered

* If a field is blank, do not use it to filter values

* Print out a nicely formatted xhtml table that contains all matching table rows

I know it isn't formatted just yet but I'll worry about that once it displays the above

I don't even know if I'm doing the best or most efficient way...

I have a xhtml form that is using the post method and is sending the information to this code, I will post just in case.

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 '='Pamela'' at line 1

Is the error I'm getting.

The php script works when I comment out all the if statements and just do a query = "Select * FROM lab5";

$query = "SELECT * FROM lab5 WHERE address = '$address'";

doood · March 23, 2007

hrmm, well I changed all my queries to look like that but now it doesn't return anything at all

and when I leave the fields blank it says no query was returned.

btherl · March 23, 2007

The problem before was that you were sticking strings together with no spaces, so your queries would look like this:

SELECT *FROM lab5WHERE address = '$address'

As for what your problem is now.. try printing out the query you are about to run, to make sure it looks like you expect it to.

That's what my code looks like now and I think it's working completely but now I just don't know how to filter out results, like if the user specifies 3 fields or more, I'm not sure how to build up the query to where only that one person being searched for is displayed.

Have an where clause array, and have each of the pieces thaat the user requested added to this array, then join this with " OR ", and then pre-pend "SELECT * FROM lab5 WHERE " if this array has length.

hrmm sounds way beyond my capabilities, but I'll give it a shot, thanks

This is fairly simple PHP work... if you're having trouble, direct any question to that forum.
