[Trouble logging in travian script]

The problem is in index.php BEFORE the "require()" that includes boot.php.

[PayPal integration]

Nice find fastsol, although, I really don't like the way it is set up.  A lot of redundant data input, which leads to great chances of data corruption.

[PayPal integration]

Yes, Paypal has an API that handles everything.  You send the total amount of the sale, along with the sale items, then the payer approves the sale.  

I haven't used the new API, as it has been a few years since I did paypal integration.  I just looked over the API, and it seems to be more complex than it used to be (payments are now 3 step processes).  So, yeah, have fun with that.

Things to think about:

Do you want Paypal to handle credit card info?
If not, does your site have SSL? (it will need to).

Anyway, start here http://https://developer.paypal.com/docs/integration/web/accept-paypal-payment/

[help php Rotate PNG image]

I'm voting a no ban.  I love to see people blow up because they can't follow directions.

[Only one row shown in table]

Have you run the query in mysql console, or phpmyadmin or other interface, to see what it returns?

[help php Rotate PNG image]

Did you read the post that Barand made, and you quoted?

He gave you a script, called im_rotate.php, then he gave you TWO different image elements.
One image element called the image, the other called the script.

[Only one row shown in table]

You will never "have that skill", unless you first try and make that skill.  Don't doubt yourself, push through that, know that you can.  Follow the syntax, and it will all come together for you. http://https://dev.mysql.com/doc/refman/5.0/en/join.html

PS. The reason you are only getting one row, is you are only asking for one row.  You haven't ask for the rest from the resource.

[Can anyone help with code for uploading a picture from MySQL?]

You also have an error in your sql syntax.

$query_image = "SELECT * FROM acc_images acc_ id='$id'";

Should be:

$query_image = "SELECT * FROM acc_images WHERE acc_ id='$id'";

[PHP Code not inserting into MySQL]

You cannot mix mysql functions with mysqli functions.  They are two different libraries.  You should be using mysqli, and NOT mysql.  

[Any WordPress expert around here?]

These are all notices, and are being shown because the code is written, well, poorly.  

All of these are just notices that the script is trying to use variables/indexes that do not exist.  The author did not check the variables before trying to use them.

You have a few choices:

A: ask the author to fix the script (recommended).
B: fix the script yourself, by adding in some validation.

C: suppress the notices through the php.ini and hope everything works fine (not recommended).

Example

 

$std = $option['std']; //this is one of the indexes listed in the notices. 
 
//a more proper way is to check if this index exists before using it.
$std = !empty($option['std']) ? $option['std'] : null; //if the index 'std' in the $options array is not empty, then assign it to $std, otherwise assign 'null' to the variable $std.

[SELECT query is only SELECTING/CHECKING the first row, how do I SELECT/CHECK all]

If this is the actual code

if(!empty($_SESSION[UserID]) and $a5['listingid'] == $_GET['id'])

You can't use "and", it should be &&

Yes you can use 'and', it is just a lower precedence than &&. http://http://php.net/manual/en/language.operators.logical.php

[Parse incoming Post data into an array]

The REQUEST_URI you are wanting is being populated via the $_SERVER superglobal.  You can get it directly by calling $_SERVER['REQUEST_URI'] instead of trying to find it in a multidimensional array.

As far as parsing it?  Who knows, I have no idea what you are wanting out of it.

I am going to guess that you want the uri query string parsed into an array.  If so, this will give you that, NOTING however, that if the value is empty, the key will not be in the array.  From your string given, this would be caller_zipcode, etc.
Array held in $parsed_uri

$pattern = '/(?<key>[a-zA-Z]+?)(?=\=[^&])\=(?<value>.[^&]+)/';
$string = $_SERVER['REQUEST_URI'];
preg_match_all($pattern,$string,$matches);
 
$count = count($matches[0]);
for($i = 0; $i < $count; $i++) {
$parsed_uri[$matches['key'][$i]] = $matches['value'][$i];
}
unset($matches);
echo '<pre>' . print_r($parsed_uri,true) . '</pre>';

[PHP Script Firing Unattended]

To cancel a script if no form was submitted, this will do.  

Applies to scripts that do nothing but form processing.

 

if($_SERVER['REQUEST_METHOD'] != 'POST') {
exit();
}

[Idle times]

You don't need to use exit(), unless you want the script to stop running. Otherwise, you are on the right track.

[PHP Class sharing?]

Of course you don't have to put all classes in one file.  That is what include is for.

[PHP Class sharing?]

Dependency Injection is the terms you are looking for.

class what {
 function __construct(ever $ever) {
  $this->ever = $ever;
 }
 
 public function DIme() {
 return $this->ever->me();
 }
}
 
class ever {
 public function me() {
 return 'Method in class ever.';
 }
}
 
$ever = new ever();
$what = new what($ever);
echo $what->DIme();

You could use a foreach:

}

[Failed to open stream?]

Most PHP files can be set to 640 with directories set at 755. PHP needs read/execute permission on directories in order to enter a directory, but it only needs to read a file.  Only shell or binary scripts need to execute a file.  Any file that is called by a user directly should be at least 644.

 

If your directories are set to 755, and your included files are at least 640, you need to check the file owner/group to make sure it hasn't been changed.

[{HELP} Need someone to help me with project]

Can you explain this statement a little bit more, like how I should set the SQL Table up. (Mostly the ":user LIMIT 1" part, I understand the rest)

 $sql = 'SELECT password FROM user WHERE username = :user LIMIT 1';

 

and a little on creating the Key for hashing?

 

 

:user = placeholder for the prepared statement, it is exchanged by the database (If pdo is started properly) when the statement is executed.

//Then bind the username to the query.

$stmt->bindParam(':user', $_POST['user'], PDO::PARAM_STR); //send the 'user' index from post to the database on execute, so that the exchange of :user can happen.

LIMIT 1 = "only return 1 row from the database", this should be redundant, because you shouldn't have more than 1 user with the same username.

 

I'm not sure what you mean by key.  The algorithm, the cost, or the salt?
