问题
I am trying to get MySQL to work for my form submissions. I am having a problem when I try to insert into a table.
When I put information into my form and click submit (in this example the information is "Idea" in one field and "Description" in the other) I get this response:
"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 'desc) VALUES ('Idea','Description')' at line 1"
I am running a .php file from a webserver to execute this script.
Here is my current code:
<?php
mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("date_ideas") or die(mysql_error());
$title=$_POST['title'];
$title=mysql_real_escape_string($title);
$desc=$_POST['desc'];
$desc=mysql_real_escape_string($desc);
$submit="INSERT INTO ideas (title, desc) VALUES ('$title','$desc');";
mysql_query($submit) or die(mysql_error());
echo ("Idea submitted. Click <a href='Webroot/submit.php'>here</a> to go back and post another idea.");
?>
If you call an echo of the variables used it succeeds at passing through the information, so that's not the problem.
回答1:
It may be because desc is a keyword in SQL. Try a different name. desc is used to sort results in descending order.
In general I would recommend to avoid to use reserved words for column names.
回答2:
desc is a reserved keyword (short for DESCENDING in ORDER BY).
Enlose it into backticks:
INSERT INTO ideas (title, `desc`) VALUES ('$title','$desc');
