Question

I can’t find out why when I click my submit button it doesn’t process the data. I currently have a query as such.

 $link = mysqli_connect("$server", "$user", "$pass", "webdb");
 $page = mysqli_real_escape_string($link, (string) $_POST['page']);
 $content = mysqli_real_escape_string($link, (string) $_POST['content']);
 $query = "UPDATE `pages` SET `content`='$content' WHERE `name`='$page'";
 mysqli_query($link, $query);
 mysqli_close($link);
 header("location: index.php");
 ?>

To connect to this query I have my form that submits the data.

<form action="update_content.php" method="post">
<textarea name="content" cols="60" rows="10"></textarea>
<input type="hidden" name="page" value="Index" />
<br /><input type="submit" value="Update" />
</form>

Everything looks to be correct from where I stand. I’ve been racking my brain and looking all over the web for hours now and I cannot find a solution here.

Answer 1

Step 1 :

Print the query variable, so that you can know the query is constructed well.

(Comment the redirection so that you can see the query output)

Step 2:

If the values passed in the query aren’t correct or empty, fix this by printing the
passed params (you can print $_REQUEST – Which will show all the values posted)

Step 3

if all these are correct and if the query is not executed correctly, then check your
database connection.

You can print out the connection variable $link to see if a connection is made successfully.

These these steps will help you sort out the issue.

Let me know if these steps doesn’t help you.
