I'm new to database so please be specific if possible. Thank you! also if anyone could point me to a similar, "working" tutorial that would help ALOT! </p> <p>trying to follow this tutorial: <a href="http://teamtutorials.com/web-development-tutorials/editing-mysql-data-using-php" rel="nofollow">http://teamtutorials.com/web-development-tutorials/editing-mysql-data-using-php</a></p> <p>i'm using wamp server, so the database log in is correct. I mean it displays the data, just doesn't edit it.. The error i'm getting is :</p> <p>Notice: Undefined index: ID in C:\wamp\www\test\updateinfo.php on line 6</p> <p>i get that even if i change post to $id = $_POST['ID'];</p> <p>Ok I changed the $_POST['']; to $_POST['id']; , still had the same error.</p> <p>Than I read online to add a @ to the front so now it looks like this: @$_POST['id'];</p> <p>That too off all the errors. but not my data base is not been updated. Everything goes through with no errors but no data is been changed??</p> <p>Also when i tried to remove backticks I get this error:</p> <p>Parse error: syntax error, unexpected T_STRING in C:\wamp\www\test\updateinfo.php on line 12</p> <p>So i left them the way they were...</p> <p>Could it be because i'm using a local server? This should be all simple not sure what i'm doing wrong here.. I mean i literary copied everything over from the tutorial. </p>

    3. COIs the user for your database actually `root` with no password? If not, you'll need to insert the actual username and password as the second and third parameters for `mysql_connect` at the beginning of the script (it's called a script, not an executable).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
