But now you're doing two queries for every insert. If you simply made your columns unique and let the database handle it, you'd only have to do one INSERT. Then check affected_rows() or mysql_error() to see if either no rows were affected (no rows inserted) or the error mentions duplicate. If either is the case, the row wasn't inserted because of a unique constraint. If there is an error but it's not duplicate or whatever, then it's another error and you should show it. ---John W. Holmes... Thanks for the tips, I'll work on that. In the meantime, this database is pretty low useage, very specialized information for a small market segment, so for now it will be okay. It'll never have hundreds or thousands of hits per day. But I will look into making the suggested changes.

[PHP-DB] address info, forms, maintanance
I need to modify some company web pages that include a form for asking the company departments questions, such as service dept, etc. As the forms are currently built there is some field validation but no cookies. This info is saved in a mysql database, problem is, there are duplicate entries, every time an end-user posts a question. What kind of code do I need to add to these existing pages to prevent duplicate entries in the database? (Manually scanning through and deleting dupes is a real drag.) And what about cookies? Could I make use of these on these pages? I haven't worked with cookies yet, so am not sure where to start with that part.

Hello!! Are talking about the same Post Question??? On another words, what is being duplicated?? If not, you can use auto_increment.

Re: [PHP-DB] address info, forms, maintanance
Chip, Given that you have duplicate entries, then one field, or a combination of several fields, will probably be unique. Before adding a record execute a SELECT, using the values from the form against that combination. If the number of records returned is greater than 0, then execute an UPDATE query, otherwise an INSERT. Now, that information is so vague to be almost useless, for it begs a number of other questions, such as How many questions are end users allowed to ask? How are questions flagged for expiration or completion/solution? What kind of mix of questions do you allow? Cookies only store a bit of information on the user's browser. There's nothing magic about them - google for netscape cookies. I don't think they'd be much help to you here.

This info is saved in a mysql database, problem is, there are duplicate entries, every time an end-user posts a question. Do you mean that when I hit submit there are duplicate entries submitted or that it may match what someone else has submitted and become duplicate? If it's the second case, wouldn't that be optimal? You'd know that X people had the same issue/question and you can reply to each one when it's resolved... What kind of code do I need to add to these existing pages to prevent duplicate entries in the database? Makeing the column unique is the easiest way. If you get a duplicate error from mysql_error(), then just ignore it because the problem is apparently accounted for. (Manually scanning through and deleting dupes is a real drag.) No one does anything manually... :) Easiest way to fix your data now would be to make a new table with UNIQUE columns where you need them. Then do an INSERT INTO ... SELECT to move the data from one table to the other. Duplicates will be ignored by the new table. Proceed as normal... :) And what about cookies? Could I make use of these on these pages? I haven't worked with cookies yet, so am not sure where to start with that part. Do you need to remember anything that the user enters in the form that's specific to that user? That's all cookies are... a variable that you store on the user's machine. If you don't already have a reason for them, you probably don't need them. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] address info, forms, maintanance
Chip, What's the database being used for then, if not to store and track questions and replies? If only as a repository of addresses that 's rather useless. Unless you want to track the frequency of user's questions, then you could update a counter field for their email address. If you've not gone down the road too far with this, there are some help desk type PHP solutions out there.

Just for those who asked - this is a database of end-user names and addresses for a mailing list. The questions posted are kept by the department that responded to them. No one here has ever asked or implied a need to have the messages saved to the database, what they do with the message is their game, not mine. I'm just cleaning up their existing code a bit. -- Chip Miles Thompson [EMAIL PROTECTED] wrote on 06/04/2003 08:31:14 AM: Chip, Given that you have duplicate entries, then one field, or a combination of several fields, will probably be unique.
