What does it show if you remove the if?

Alright. So what is your question about error handling? What's not working? And can I assume you're aware of the syntax errors in your code? And a few other errors...

Your character encoding settings are not consistent. Make sure that - Your HTML pages are using UTF-8 because they do not by default; use a and/or configure your server and PHP code to return the UTF-8 encoding - Your database has utf8 as the default encoding; a SHOW CREATE DATABASE will the encoding - Your table is using the utf8 encoding; a SHOW CREATE TABLE will show the encoding - Your table columns are using the utf8 encoding; if your table is but your columns are not then a SHOW CREATE TABLE will show it - Your database connection is using the utf8 encoding; for MySQL you have to pay attention to both the server and client settings Missing any one of those can cause the problem you're seeing.

What is your question about error handling? What's not working? And when you answer, post your code too.

Well, you need to decide which of those you want. The first is self-contained to your application, but someone has to go to it before they can see their "bookmarks" - typically called "favorites" instead, to avoid confusion. The second means the user has a link in their browser they can click from anywhere, but if a user has a lot of bookmarks then that could be awkward for them to deal with. Note that this isn't a technical question. It's about what your users need and want to be able to do.

Before getting to your problem... which I haven't been able to decipher yet... What is a "bookmark application"?

The offset is incorrect: $myoffset will be a page number like 1,2,3 when it needs to be a starting offset like 0,25,50. I suggest putting off building the query, or at least the LIMIT part of it, until after the pagination object is available - then you can use its calculations for the offset (in the offset() method). After you have the query, execute it and display the results however you want. Strictly speaking the pagination work is really just about getting the page number in the URL, getting links to navigate between pages, and adjusting the query's LIMIT accordingly. And you have that part.

Makes sense: there isn't actually any code in there to execute the query (which is supposedly contained in the $mysql variable), nor to display the results. Does the tutorial add that code later? And what does it say about the query? Because what you have in $mysql is incorrect.

It's very much a per-server thing, and you'll find that most servers only allow .php (and occasionally .php5) so that's the most reliable extension to use. However you can often add some configuration, even as just a regular user, that will allow it.

The file is named "reviewparts.html" and that server isn't configured to execute .html files as PHP code. If you look at the source of the page you'll see the full PHP code - as if it weren't even executed at all. Try simply renaming it to "reviewparts.php".

That would be trying to get the value of a property, such as $variable = $object->property;or $variable = $object->property->another_property;

I didn't put the variables in this time but otherwise it's correct. $valid = ((ip2long($mask) | ip2long($address)) == ip2long($mask));

Make sure you're connecting to the right server, otherwise you'll have to contact them to find out why the server is read-only.

I was hoping for the full array, not just part of it... Are you sure $menu is starting off with the values you expect? That div07-div10 and mod001-whatever (mod010 I would guess) all have values?

Okay, so you have a subnet mask and you want to check whether a given network address is valid for the mask? Pretty much everything to do with IP addresses is easier to do with straight numbers. Check that (ip2long(mask) | ip2long(address)) == ip2long(mask). - The mask has all network address bits set and all host address bits unset - Bitwise OR will only set bits - If the result differs then it must be because new bits were set, and those bits must have been in the host address portion, and those bits needed to remain unset to stay valid

What was the source $menu?

Let's establish some terminology: - 192.168.12.34 is your IP address - 255.255.255.0 is the netmask - 192.168.12.0 is the network prefix = IP address & netmask - 0.0.0.34 is the host part = IP address & ~netmask If you're trying to determine whether an IP address matches the network prefix then you'd want the code I posted. If you're trying to determine whether an IP address belongs within the network then you need to know the correct network prefix too. Now, what are you trying to get?

Yup. So is this still a question about how to do the check using PHP code? (What about the code I posted?) Or something else?

This is definitely not a job for a regular expression. Is there any particular reason you want to use one? Because the normal answer is $valid = ((ip2long($ipaddress) & ip2long($netmask)) == ip2long($ipaddress));

Where are you sending the email? Where are you loading the email template? Where is the email template located?

So you're concerned that someone can mess with your URLs and put all sorts of bad stuff into the "id" value? Honestly, I think it's better to treat invalid values (like "--35") as invalid values, not try to somehow force them to be valid. Take the same action you would as if someone entered "id=foo" or "id=" or removed the id entirely.

If that "Cannot modify header information" error message was referring to the setcookie() line then that's your problem: you can't call it after there has been any output. Rearrange your logic so that you set the cookie before beginning output. Oh, and your code says "clicked_twice" in some places and "used_twice" in others.

Why did you remove the slashes from the JSON string?

After you change the function to be preg_replace_callback, you also have to change the second argument to be a function and not a mere string. The simplest way is to use an anonymous function like function($matches) { // ... } $matches will be an array just like how preg_match() works, what with [0] being the full string and [1] being a captured group. Inside this function you call constant() and return whatever you want the replacement to be. Give that a shot. If you still have problems, post the code you tried.

That means your query failed (the boolean is false). What does mysqli_error say? How can you be sure that $project_id has a value?
