PHP - Merging Images And Text

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

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. (:

$query = "SELECT
Table1.*,
Table2.A,
Table2.B,
Table2.C,
Table2.D,
Table2.E
FROM Table1
INNER JOIN
Table2 ON Table1.A = Table2.A

Issue is that there are multiple matches for some instances, like so:

Table1.A value = 1777 (only once since it is a UniqueID)
Table2.A value = 1777 (3 records with this ID value)

So I will get 3 records returned since Table1.A matches 3 records in Table2.A. I want to merge the 3 records in Table2 into 1 record and then match that with Table1 where the UniqueID is the same. Make sense?

Hello guys,

I don't really know php but I am always been able to copy/paste it and move stuff around on my wordpress website until now.

This last challenge is beyond my skills though (I am sure it will be trivial for you).

So I have this code snippet to show a video duration

    <?php
  global $post;
  $video = cbc_get_video_data( $post );
  if( $video ) {
    echo $video->get_human_duration();
  }
?>

And I have this code to show a post title

if ($show_title) {
        $title_content .= apply_filters( 'uncode_before_body_title', '' );
        $title_content .= '<div class="post-title-wrapper"><h1 class="post-title">' . get_the_title() . '</h1>';
        $title_content .= uncode_post_info() . '</div>';
        $title_content .= apply_filters( 'uncode_after_body_title', '' );
    }

I want to show the video duration right before the post title and in line with it, so inside the h1 tag. How to do that?

Thanks for any help!

 

 

Hello,

I want to 'join' two corresponding array values together as in the example below.

$one = array('tomato', 'ham', 'bacon');
$two = array('soup', 'sandwich', 'roll');

$final=array(?)

//Desired answer =  (tomatosoup, hamsandwich, baconroll)

Is there a php function that can do this, or a series of functions? I am aware of array_merge but this only alternates the values from what I can see.

Ideally there should be a check performed that the two are the same length before completing a merge.

New to this, many thanks!

Hi wondering if there's a simple way to merge or update the data from one array to another . I've tried merge data but it just adds additional records rather than merging them off one common key.   The array is just simply adding a name to another array the format of both is as follows   Array 1   [0] => stdClass Object
(
[name] =>
[market] => Football
[selection] => 7051575

)   )   Array 2   Array
(
[0] => stdClass Object
(
[name] => Something
[market] =>
[selection] => 7051575

) )     There are other fields but I'm just trying to merge the name from Array two into Array one using the selection as a common key. Is there an easy command like merge or do I have to loop thru the arrays to add the data.   Thanks

Hi guys,   I wonder if you can offer any advice?   I have two user database tables that are about 70% identical. The problem is that with one of them, the phone number for each user has been cut short by two digits (it was an error on my part early on in the database design).    What I need to do is to get the values from both tables and put them into separate arrays then compare the arrays in a loop. If, say, the first five digits of the phone number in each row of the first table match one entry in the second table then update the second table with the phone number (the full length one).   I'm about puzzled about how to approach this, I've still got a lot to learn about array functions, it seems like it should be fairly simple but I'm a bit lost as to where to begin.   Any advice would be massively appreciated!    

Hi All,

i am trying to Generate a image dynamically.

hi, how is everybody doing? i hope well, i have a problem with some php code. i am trying to split some text in two parts once they have been split, they are display, but sometimes the php code break the source code of the page such as images and instead of the image i get the source code like this

i have tried for about 2 days now to fix it and i haven't been able to, so any help or guidence would be greatly appreciated. this is the code that i am currently using, i have tried to change the variable in the $findTag but nothing seems to work
Code: [Select]
<? php
$article =$this->article_>text;
$countchars=strlen($article);
$divide=$countchars/2;
$firstpart=substr($article,0,$divide);
$secondpart=substr($article,$divide);
//i keep changing the <p /> variable to <img /> and $image and many others but nothing seems to work
$findTag = strpos($secondpart, "<p /> ");
$var = $divide + $findTag
$firstpart = substr($article, 0, $var);
$secondpart = substr($article, $var);
?>
thanks

I'm trying to make my text and images into clickable links. The images and text are in a database so its getting really tricky for me since I'm new to PHP. I've tried many different ways without success.

Here is a snippet of the code I'm working with. As you can see, I'm also working with an image re-sizer. I would really like to make those images and text
clickable links(i.e. Title). Any help is appreciated!

if ($res) {
while ($newArray = mysqli_fetch_array($res, MYSQLI_ASSOC)) {
$detail = $newArray['id'];
$photo = $newArray['photo'];
$id = $newArray['title'];
$price = $newArray['price'];


list($width) = getimagesize($photo);
// set the maximum width of the image here
$maxWidth = 100;
if ($width > $maxWidth)


echo "<p><img alt=\"Image\" width=\"$maxWidth\" src=\"$photo\" />";

echo "Title:".$id." Price:".$price."<br/";

Ok, first off CSS is definitely not my strong suit so bear with me here.  This is my code:

	#grid{
		width: 100%;
	}

	}
	
	a.clickable-div {
		display: block;
		height: 100%;
		width: 100%;
		text-decoration: none;
	}
	
	.img {

This is the browser output.  A couple things are wrong:   1. Why aren't the images scaling so they are all the same size?  I assigned the same CSS class to each of the images but they are all appearing differently.  The original images are all the same size.   2. Why are my buttons in the far right corner?  I want to have them centered below the images so as to prevent the horizontal scroll bar, which I hate.     Attached Files  output.png   232.09KB   0 downloads

the idea on what im doing is like a converter, like showing what your name would look like with certain images per letter, when you input text (your name for example) and when you press the submit button you would get a series of images in a row that represent each character that you typed.   here is the example that i did...
