  1. In Topic: Apprenticeship Advice

    Posted 23 Apr 2015


    If you are a beginner you should just learn programming in general first. If somebody is willing to teach you web development, that's not a bad start. (Given that you're being taught proper techniques.) If you become competent at web development, you shouldn't find it very hard to switch over to mobile development.

    Learning languages is trivial. Anybody can do that in a matter of weeks. Learning how to use those languages to get something done - how to solve problems in a logical way - that's another thing entirely. That's the thing to focus on first, and you can do that in pretty much any language.
  2. In Topic: Prepared statements

    Posted 17 Apr 2015

    Why include the { and } in the actual search string?

    He's missing the quotes around the array element name, but apart from that I can't see a problem with what he does.
    $name = "%{$_POST['name']}%";
  3. In Topic: User Registration - Query leads to white screen.

    Posted 14 Apr 2015

    Your preg_match is still checking the $username variable you removed when you took out the sanitation. You need to replace that with the POST value.

    I'm still confused how this works. bind_result puts the result of the query into, in this case, $usercheck, right? So what's the purpose of fetch?

    The bind_result method only associates variables with columns in the result set. It doesn't actually get any data. That's what the fetch method does.

    Consider that this is all designed assuming that the result of a query can contain more than one row. First you bind a variable to a column, then you fetch each row in a loop, wherein the bound variable contains the value for the current row.

    And, would I be able to use an if($usercheck = "") to check for an available username?

    Sure, you could fetch the username and check if it returned a valid value.

    However, I would recommend a different approach. Databases like MySQL can easily figure this stuff out for you, and return to you a clear result. In this case, you can use the MySQL COUNT() function to have MySQL figure out how many users your query finds, and have it return whether or not it finds any matching rows. Then you could just use that boolean in your if condition.
    SELECT COUNT(*) > 0 FROM userTable WHERE username = ?

    bind_result( userExists )
    IF userExists :
        print "User exists!"

    (P.S. That's just pseudo code. I can't remember how MySQLi's function calls look exactly. Haven't used it for quite a few years; not since I discovered PDO)
  4. In Topic: URL Masking

    Posted 9 Apr 2015

    It's basically the same thing, through, when you think about it. The "Thank You" page could just as easily redirect the use to the download link, rather than email it.
  5. In Topic: Register Form using php

    Posted 8 Apr 2015

    What have you tried?

    There are literally millions of articles/blogs/forum posts about this available online. It's one of those things every single PHP developer does in their early days.

    I can't seem to like your reply to my jQuery post an hour ago (fantastic explanation it was), because the Javascript in my browser is somewhat malfunctioning. I will like it later, ok?
