phpnewbie26 0 Report post Posted January 19, 2015 Hi, I am having an Issue inputting data into my database with this code. I tested the connection, which works fine, but when I try to submit the form I get the "die("lid query: " . mysql_error());". Any Ideas? <!doctype html> <html> <head> <meta charset="utf-8"> <title>Untitled Document</title> </head> <body> <form action="thispage.php" method="POST"> <input type="text" name="name" placeholder="Check-in Name"> <input type="submit" value='submit'></form> <?php if (isset($_POST['submit'])) { $name = $_POST['name']; $host ="localhost"; $username = "username"; $password = "password"; $dbname = "database"; $con = mysql_connect($host, $username, $password, $dbname); //Check Connection if (!$con) { die("Could not connect: " . mysql_error()); } //Select your database mysql_select_db("database",$con); //Check to make sure the database is there if (!$mysql_select_db) { die ('Can't use the db : ' . mysql_error()); } //Run query $insert = mysql_query("insert into Users(name) values ('$name')"); } //Check Query if (!$insert) { die("lid query: " . mysql_error()); } echo "Data inserted"; mysql_close($con); ?> </body> </html> Quote Share this post Link to post Share on other sites

Your code is vulnerable to SQL injection, making your site really easy to hack. You should do two things: 1. Don't use the mysql library because it's vulnerable to security threats, change to mysqli or PDO. 2. Learn prepared statements to ensure without a doubt that you won't have problems with SQL injection. Quote Share this post Link to post Share on other sites
phpnewbie26 0 Report post Posted January 19, 2015 The script gets to the //Check Query part and fails. It echos out the "lid query" and doesn't put anything into the database. I tried to just remove that portion, but it still wouldn't input any data into my table. I am very new at PHP and am basically getting code off the internet and throwing it into some pages and seeing if it works. This is a very simple script, I just dont see why it isn't working?

Ingolme 1,011 Report post Posted January 19, 2015 It sounds like $_POST['submit'] isn't set, so the query isn't being executed. You should put your code in a [CODE][/code] tags so we can see it properly. Here's what your code looks like: <?phpif (isset($_POST['submit'])) { $name = $_POST['name']; $host ="localhost"; $username = "username"; $password = "password"; $dbname = "database"; $con = mysql_connect($host, $username, $password, $dbname); //Check Connection if (!$con) { die("Could not connect: " . mysql_error()); } //Select your database mysql_select_db("database",$con); //Check to make sure the database is there if (!$mysql_select_db) { die ('Can't use the db : ' . mysql_error()); } //Run query $insert = mysql_query("insert into Users(name) values ('$name')");}// This section of code runs regardless of whether $_POST['submit'] exists or not//Check Queryif (!$insert) { die("lid query: " . mysql_error());}echo "Data inserted";mysql_close($con);?> Quote Share this post Link to post Share on other sites
