How Can I Prevent Sql Injection In Php Registration Form?
I am attempting a registration form that saves the data into a sql db. I'm not doing form validation just yet as what is most troubling me is getting this stuff onto sql.
I'd appreciate any advice!!I have a form.php file that should be doing the hard work. When I submit my form, at this point, I get a blank screen and nothing loads into the database. And I have an html file that contains this: User InformationFirst Name:Last Name:Password:Email:Cellphone:What Is Your Experience Mountain Biking?n00bIntermediateExtreme
Any idea what the heck I'm doing wrong? Solved my own problemyou have registered sucessfully';echo 'Thank you for your registration to the ';mysqlclose($connection);?.

SQL injection is a type of injection attack. Injection attacks occur when maliciously crafted inputs are submitted by an attacker, causing an application to perform an unintended action.

This question already has an answer here:.28 answersI've build a website that will be going live soon and just have a couple questions about preventing SQL injection, I understand how to use mysqlirealescapestring but I'm just wondering if I have to use that on all variables that I'm getting for my SQL statement and do I have to use it when I'm doing select statements also or just on insert update and delete? Also what other security would you recommend me implementing before I put the site live, thanks in advance for any help! Any query can be injected whether it's read or write, persistent or transient. Injections can be performed by ending one query and running a separate one (possible with mysqli), which renders the intended query irrelevant.Any input to a query from an external source whether it is from users or even internal should be considered an argument to the query, and a parameter in the context of the query. Any parameter in a query needs to be parameterized. This leads to a properly parameterized query that you can create a prepared statement from and execute with arguments. For example: SELECT col1 FROM t1 WHERE col2 =??
Is a placeholder for a parameter. Using mysqli, you can create a prepared statement using prepare, bind a variable (argument) to a parameter using bindparam, and run the query with execute. You don't have to sanitize the argument at all (in fact it's detrimental to do so).
Mysqli does that for you. The full process would be: $stmt = mysqli-prepare('SELECT col1 FROM t1 WHERE col2 =?' );$stmt-bindparam('s', $col2arg);$stmt-execute;There is also an important distinction between parameterized query and prepared statement. This statement, while prepared, is not parameterized and is thus vulnerable to injection: $stmt = mysqli-prepare('INSERT INTO t1 VALUES ($POSTuserinput)');To summarize:. All Queries should be properly parameterized (unless they have no parameters). All arguments to a query should be treated as hostile as possible no matter their source.
It will be closed in seconds, but just to make things straightI understand how to use mysqlirealescapestringI am afraid you are not.if I have to use that on all variables that I'm getting for my SQL statementdefinitely not.this function have to be used to format SQL strings onlydo I have to use it when I'm doing select statements also or just on insert update and delete?ANY SQL statement. But again, not 'using mysqlirealescapestring' but formatting your literals completely and properlyAlso what other security would you recommendregarding SQL security - you have to properly format not only strings but literals of any kind. And each require distinct set of formatting rules.
