PHP - Merging File Help

I currently have a flat file user registration and login in system. I also have a simple guestbook which i didn't code myself, the guest book currently requires the user to type in there name and e-mail address to make a post. how ever i would like them to have to login and if they aren't logged in then don't display the guestbook.

Hi there,

I am using HTML forms to post values from a data entry page. When they arrive on the second page - I have to extract them from the POST array. This is fine, but I now have to merge them somehow.

When I use print_r to view the POSTed data, I see:

Code: [Select]

    [namesUnem] => Array
        (
            [0] => Brian
            [1] => Richard
            [2] => Sarah
        )

    [commentsUnem] => Array
        (
            [0] => Brian Comments here
            [1] => Richard Comments should be entered here
            [2] => Sarah's Comments were also entered here
        )

    [namesHW] => Array
        (
            [0] => Sally
            [1] => Kate
            [2] => William
        )

    [commentsHW] => Array
        (
            [0] => Sally Comments here
            [1] => Kate's Comments should be entered here
            [2] => William's' Comments were also entered here
        )


There are 2 more such arrays being POSTed. I would need to merge in order to see the following:

Quote


[Name] => Brian [Comment] => Brian Comments here [Type] => namesUnem
[Name] => Richard [Comment] => Richard Comments should be entered here [Type] => namesUnem
[Name] => Sarah [Comment] => Sarah's Comments were also entered here [Type] => namesUnem
[Name] => Sally [Comment] => Sally Comments here [Type] => namesHW
[Name] => Kate [Comment] => Kate's Comments should be entered here [Type] => namesHW
[Name] => William [Comment] => William's' Comments were also entered here [Type] => namesHW




Any help greatly appreciated

Kindest Regards

This must be easy enough, but I'm a noob so go easy on me, please :-)   I have two pieces of code and they're working well on their own. All I need is to put these two conditions into one query.   The first one:

<?php
function childtheme_cat_limited_blog( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $query->set( 'events_categories', 'mycategory1' );
    }
}
add_action( 'pre_get_posts', 'childtheme_cat_limited_blog' );
?>

And the second:

<?php
function childtheme_cat_limited_blog( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $query->set( 'category_name', 'mycategory2' );
    }
}
add_action( 'pre_get_posts', 'childtheme_cat_limited_blog' );
?>

I'm sure it's a piece a cake for you guys, but I can't figure it out for the life of me, so any help would be greatly appreciated!   Thank you!   (My goal is here to display posts from two categories on a homepage of a Wordpress site, but to complicate things the two categories are from two different post types.)

What I'm looking to do is analyze an array of coordinates and generate a convex-hull type outline of all independent polygons merged. Convex hull isn't ideal for my situation as I need the outline detailed.

From:


To:


This is how the data is arranged (The keys are just for reference):

$array['Group_01']['Polygon_01'] = array('latitude, longitude', 'latitude, longitude', 'latitude, longitude', etc.);
$array['Group_01']['Polygon_02'] = array('latitude, longitude', 'latitude, longitude', 'latitude, longitude', etc.);
$array['Group_01']['Polygon_03'] = array('latitude, longitude', 'latitude, longitude', 'latitude, longitude', etc.);

$array['Group_02']['Polygon_01'] = array('latitude, longitude', 'latitude, longitude', 'latitude, longitude', etc.);
$array['Group_02']['Polygon_02'] = array('latitude, longitude', 'latitude, longitude', 'latitude, longitude', etc.);

etc.

Basically in that scenario I would like to join ALL of the coordinates to form an outline in both 'Group_01' and 'Group_02' based on the polygons in 'Polygon_xx' under that group. Each outline independent of itself. So 'Group_01' would be a union of $array['Group_01']['Polygon_01'], $array['Group_01']['Polygon_02'], and $array['Group_01']['Polygon_03']. Then 'Group_02' would be a union of $array['Group_02']['Polygon_01']  and $array['Group_02']['Polygon_02'].  This would output an array of something like $array['Group_01']['Unified'] and $array['Group_02']['Unified'] etc.

Is this possible? Any help would be greatly appreciated.

Thanks.

Hello.
I'm currently trying to write a code to merge two separate images together, but for the life of me I can't find anything that works.

Basically what I'm trying to do is add a "marking" (cat_stripes.png) to a pet image (cat.png). In the future I also want to use this for adding items to pets and things like that.
Both of the images have transparent backgrounds, so that needs to be taken into account. If you haven't got a clue what I'm talking about, look up Wajas or similar virtual pet sites to get an idea of how the markings work.

I just need something simple, since I don't have a site set up yet and I'm just testing some things out for a future project. I don't have any codes at the moment, since nothing has worked so far.
I'm pretty new to GD too (I'm familiar with all the basic php stuff, so don't panic), so you might need to explain some of the more advanced stuff to me.

Any help with this would be really appreciated, thanks. (:
