  1. This should be <form action="/multi.php" ...> because, assuming multi.php is in the root directory of the server, you need the forward slash to denote any address that is on the resident server and is not a GET Request via http. If it is in a subdirectory, it will be action="/path/to/file.php"
  2. I get that part, but the syntax is different in how it's deployed depending upon the language you're using.
  3. That helps my understanding of it quite a bit. (I'm quite new to SQL and have only done a modest bit of PHP- This is my first project from scratch.) . So the best structure, If I'm understanding it, is to combine everyone's data into the same table and use a WHERE statement. I'm also guessing that you can use WHERE column A=something AND column B = something else AND column C= something else (going as many columns as need be) if necessary? I'm having a hard time finding examples of SQL queries within the context of PHP that actually work.
  4. To clarify, it would be the same table structure for everyone, but would be different user-supplied data for each account, in a setting where data integrity matters, forensically speaking. It would seem that by providing the account with it's own database table, it then, worst case, minimizes the impact of SQL injection- because the injector then only theoretically would effect only one particular table Vs. the potential for wiping out the whole database (and thus effecting the integrity of the whole SQL server) if everything is stored in one table. The idea is essentially de-centralizing vs.
  5. The idea is that by pulling data from a smaller table in which all the data would be used (e.g. given a SELECT * from table argument) would be faster and more efficient than having to use the form of Select * from table WHERE parameter1=x and parameter2=y type of argument.) because it would seem that the latter takes much more time and resources to execute, and would be more secure because we're partitioning tables.
  6. The application I'm building issues an account and then basically stores a set of property information (such as make/model, serial number, etc.) to the individual account and allows the user to recall the information in his own account but not in other user's accounts. It also will allow "marking" certain property missing, etc. to display to super users (e.g. people manually verified to have a right to know the info and then granted a superuser status) using an administrative "level" model , while the system administrator has access to all of the information everywhere. My first instinct
  7. This seems to be because you're mixing obsolete sql with sqli. You can't use both in the same database call. The big problem I see with this is that you should be using prepared statements in the first place.
  8. Following the KISS principle, The way I would handle this is to have each button submit to a different php script and do a header redirect if need be. This approach is particularly useful if you can't use mod_rewrite such as if you're using nginx.
  9. What is the best table structure when constructing what will be a potentially large multi-user platform? Example- Each user inputs their own individualized information into a table, for recall only to that specific user and to certain other users defined as administrators or half-administrators super users. Would it be better to store this all in a single table, or to give each user their own individual table on formation of the account?
  10. I would have never really thought about it that way, in that I would have to double check the login script to make sure I'm not inadvertently setting a session var using post data. I'm still quite new to SQL though have dabbled a bit in php, though mostly have done content not involving databases until now. Thanks for your help.
  11. Why do I need a prepared statement IF I'm not accepting user input, and the material already in the database was derived from a prepared statement? It would seem that a prepared statement isn't necessary here because, correct me if I'm wrong" injection only concerns parsing user input into a database, not reading a database.
  12. let me guess, $user needs to be escaped in single-quotes for SQL to be able to read the variable?
  13. My first thought. (and it actually worked with the issue with $user, as I was able to successfully echo the variable to demonstrate it had been fixed.) However changing it to $priv = $row['su'] still threw the same error, as if to say that SQL isn't properly returning $row['su'] at all- but if this were the case I'd expect an SQL error a )s opposed to variable undefined.
  14. I've read that- in fact it was my fist stop in approaching this- though I'm not sure how it applies here, as none of the examples there seem to be directly on point.
