this is my php code in server where there is a table named 'questions' and i am trying to insert the data into it from the input got from the GET method using form at front end, i can figure out that data is coming properly from the client which i have checked using echo. I am getting an error as
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'name, type your question here, company)' at line 1
Don't know what is the error in the query. anyone find it out asap. thank you
You need to quote your values
('$topic', '$question', '$company')
since those are strings.
Plus, you should escape your data for a few reasons. Not let MySQL complain about certain characters such as hyphens etc., and to protect against SQL injection.
Use prepared statements:
Reference(s):
Edit:
As an example using your present MySQL API:
$topic = mysql_real_escape_string($_GET['topic']);
$question = mysql_real_escape_string($_GET['question']);
$company = mysql_real_escape_string($_GET['company']);
I don't know what your inputs are called, so that's just an example.
You mentioned about using $_GET
for debugging but using a POST method.
$_GET
to $_POST
above. Try this
<?php
$db = mysqli_connect('mysql6.000webhost.com', 'a6124751_murali1', 'default@123', 'a6124751_signup');
if (!$db) {
die('Connect Error (' . mysqli_connect_errno() . ') '
. mysqli_connect_error());
}
$topic = $_GET["Topic"];
$question = $_GET["Question"];
$company = $_GET["Company"];
$query = "INSERT INTO questions (topic, question, company) VALUES ('$topic', '$question', '$company')";
$sql1=mysqli_query($db, $query);
if(!$sql1)
{
die('Invalid query: ' . mysqli_error($db));
}
?>
Fixes in your code
The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead
You need to quote your values ('$topic', '$question', '$company')
You have to put the values in single qoutes, if that are char types:
$query = "INSERT INTO questions (topic, question, company) VALUES ('$topic', '$question', '$company')";
But you should not longer use the deprecated mysql_*
API. Use mysqli_*
or PDO with prepared statements.
