Problem with auto profile generator

[flynismo]

I just started a site, and would like to make some dummy profiles. The script I'm using included a profile generator that would assign usernames, age and location (city and state) of the "members". The problem I'm having is that the profile generator assigns a city, but not the corresponding state...due to the nature of my site, it is very important that the member's city/state matches up.
If anyone could help me out on this, that would be great...I can post the code (isn't too much; just one page about 400 - 500 lines) if it would help.

Also, my knowledge of php is very limited...this would otherwise be a very simple problem to resolve (the problem with the code is that it is not getting the state out of the database, just the city...but I don't know how to enter the code properly)

Thank you in advance for any help!

Your going to have to post your code.

Or you can download the code below in zip format if it makes it easier for you....thank you.

Also, my knowledge of php is very limited...this would otherwise be a very simple problem to resolve (the problem with the code is that it is not getting the state out of the database, just the city...but I don't know how to enter the code properly)

Its obvious from the code, (or lack there of) that you are in way over your head. This looks like a form validation class that extends another class and what you would have to do is create your own class which would probably extend this one to create your own functionality. This forum is for developers to get and offer help to other developers. I'm not saying this to be rude, I just don't want you to waste any more of your time. I just don't know of any developer here at Daniweb or any other forum that will be willing to do this for you for free. There is another forum at Daniweb for finding a developer here which is probably more along the lines of what you are looking for.

Now if you want to try to make this adjustment yourself and have specific questions about different aspects of PHP I would love to help you.

That's ok, I understand...I thought it would simply be a matter of inserting a few lines of code-didn't realize it would be this detailed.
I would love to do this myself, but as you said, I know I'm in way over my head.

Just a thought; if I created a few profiles with the profile generator, would there be a relatively quick way to manually edit the profiles (maybe through phpMyAdmin or something?)

[R0bb0b]

When viewing a table in php myadmin there is a button on the top that says browse which will allow you to view the data in the table and each row has an option to edit.

I really, really don't want to sound like I'm being lazy, but I tried doing it that way before, but it takes too long doing it that way...
Basically, what the deal is is that I'm starting a dating site, and I'm afraid that no one who visits the site will join if they see that no one is on the site. Since most people will only be interested in meeting people within x-amount of miles, I figure that I would need roughly 1,000 people per state so that there's at least a few members of each gender within reasonable range of random visitors to the site; and as members join I would remove the dummy profiles. Honestly, I hate the idea of even having dummy profiles, but it seems to be the best alternative for my situation. But anyway, I want to make ~50,000 dummy profiles, and manually editing each one in the database would take forever (took me about an hour to do 250).
Looks like the only way to do this is to get the profile generator functioning properly...but thanks for your help!

I really, really don't want to sound like I'm being lazy, but I tried doing it that way before, but it takes too long doing it that way...
Basically, what the deal is is that I'm starting a dating site, and I'm afraid that no one who visits the site will join if they see that no one is on the site. Since most people will only be interested in meeting people within x-amount of miles, I figure that I would need roughly 1,000 people per state so that there's at least a few members of each gender within reasonable range of random visitors to the site; and as members join I would remove the dummy profiles. Honestly, I hate the idea of even having dummy profiles, but it seems to be the best alternative for my situation. But anyway, I want to make ~50,000 dummy profiles, and manually editing each one in the database would take forever (took me about an hour to do 250).
Looks like the only way to do this is to get the profile generator functioning properly...but thanks for your help!

Then you have two options.
1. Spend the time that it takes to learn php, we will be happy to help you on your way. PHP.net has a huge resource of documentation and examples available. There is actually more online documentation for php than any other language, except maybe javascript, but I doubt it.

2. Find a freelancer which is not hard to do seeing there are many forums available and ask for a price quote. Give them everything, not just the little piece that you gave me and ask them how long and how much. You can even get multiple opinions.

Going with option 1...started taking the tutorials at w3 a few weeks ago. Probably sounds weird but I'm actually enjoying learning php. It sounds so simple in theory, but in practice php has been pretty tough. Right now I just know the very basics. But I'll definitely be back with questions as I go along.
