PHP - Alphabetic Grid
How i can create alphabetic grid . like on this website
http://www.vietnamworks.com/jobseekers/search.php Similar TutorialsHey folks! I am looking to build a small adventure game in PHP and the key to this will be a 3x3 (or possibly bigger) grids of squares, with the user situated in the centre. I therefore need to be able to figure out the co-ords of the surrounding squares. Presumably I will need to define the size of the master grid, then using the co-ords of the current square (defined from a database containing the users location), calculate the co-ords for the surrounding 8 grid squares. Has anyone had any experience with this? Where should I start? (Maths isn't my strong point tbh, but I can pick things up quickly) Thanks in advance! EDIT - in case it wasn't too clear, the "world map" would be something like 1000x1000 squares, but the player can only see the 3x3 grid at there location. There are good ways to keep only English characters in a string. But what is the easiest way to keep all alphabetic characters (whether in English or other languages like Russian, Japanese, etc) by removing all sign characters like !@#$%^&*()":;' ? Hi, I'm not too sure how to word this, but what I want to is to have a timetable for the 7 days of the week and 24 hours of the day, which gives 100-200 possible combinations. A user will select a checkbox and click submit which will then upload to a mysql database with the respective information. My question is, is there a way that the check box will dynamically select the day and time based on the row and column in it, as opposed to having 168 different names and values for each checkbox? I hope I have made my point succinctly but please post back if any more info is needed. Ta. I want to pull the last 8 entries from a database. Code: [Select] $result = mysql_query("SELECT * FROM `sites` ORDER BY id DESC LIMIT 8"); The problem is when I ORDER BY ASC the elements are displayed fine but in ORDER BY DESC the are messed up. Why? and how do I fix it ORDER BY DESC ORDER BY ASC CSS Code: [Select] html { font-family: segoe ui, arial, helvetica, sans-serif; height: 100%; overflow: hidden; } body { background-image: linear-gradient(bottom, #FFFFFF 16%, #E8E8E8 79%); background-image: -o-linear-gradient(bottom, #FFFFFF 16%, #E8E8E8 79%); background-image: -moz-linear-gradient(bottom, #FFFFFF 16%, #E8E8E8 79%); background-image: -webkit-linear-gradient(bottom, #FFFFFF 16%, #E8E8E8 79%); background-image: -ms-linear-gradient(bottom, #FFFFFF 16%, #E8E8E8 79%); background-image: -webkit-gradient(linear,left bottom,left top,color-stop(0.16, #FFFFFF),color-stop(0.79, #E8E8E8)); background-repeat: no-repeat; } #sites { width: 56%; padding: 10px; position: relative; left: 50%; margin-left: -29%; top: 150px; } .siteWidget { margin: 5px; padding: 10px; width: 200px; float: left; text-align: center; -webkit-transition: all 0.25s ease-in-out; -moz-transition: all 0.25s ease-in-out; } .siteWidget .img { height: 150px; -moz-box-shadow: 2px 2px rgba(0,0,0,0.25); -webkit-box-shadow: 2px 2px rgba(0,0,0,0.25); box-shadow: 2px 2px rgba(0,0,0,0.25); margin-bottom: 10px; } .siteWidget .img:hover { box-shadow: 0 0 10px rgba(0, 0, 0, 1); -webkit-box-shadow: 0 0 10px rgba(0, 0, 0, 1); -moz-box-shadow: 0 0 10px rgba(0, 0, 0, 1); } a { text-decoration: none; colour: black; } a:visited { color: black; } a:hover { color: #e90000; } h3 { margin: 0; padding: 0; } html/PHP Code: [Select] <?

I created ordered pairs and I want to plot them on a grid. Grid is about 200000x200000. Trying to figure out my game map.

Thanks in anticipation. hi trying to make a grid of two columns , data from db using mysqli and php, but it does not work...can you guys help me thanks in advance
<?php echo"<table border='0' align='center' cellpadding='2' cellspacing='2' width='70%'>";
$query = "SELECT * FROM posts";
while ($row = mysqli_fetch_assoc($select_all_categories_query)){
if($count ==0) { echo"<tr>"; }
echo"<div class='post-img'>"; }else { $count=0;
echo"<div class='post-img'>"; } $count++; } echo"</tr></table>"; ?>
this is the result
i want this kind of result
thank you Hello all: Let me give you some background, over the past 10 years I have dealt with many forums, and even built some limited PHP scripts myself for various things related to those forums. Usually modifications to expand the forums abilities. So I had thought I had a fairly good handle on PHP in general... LOL, that is until recently when I decided to take on a slightly different/larger challenge. Recently one of my forum users requested the creation of a X,Y Coordinate grid, where they could put into it certain bits of information and it would return showing them the X,Y location of thier various work attached in some way shape or form to his site. I had thought this would be a simple project, as I have worked with GD image creation before, as well as SQL statements many times, it simply should have been a blending of my exsisting knowledge into one program. While this was a unique challenge for me, its one I seem to have been unable to plug. I have searched the web extensively the last 2 weeks hoping to find a tutorial, and sadly while I can find a great many related to bar graphs and line graphs, I can't seem to find a single one related to a simple X Y coordinate graph, yet I know I have seen them done many times. I am at a total loss on this one and so far my attempts have garnered me 0 results. I can't even create a 20 x 20 grid with any success... LOL. I am hoping one of you would be kind enough to post a tutorial, with a simple code that would produce a grid using GD, or even some other form of image generation, with 1 - X Y plot in it generated either from SQL or from the program its self, so that I could see a working version and with luck go from there to expand it to my needs. Thank you. Hi guys. I'm trying to build a games site for a friend. Currently, the front-end (HTML/CSS) of the site is done. Now, I want to make a way for him to easily add games to the site. Ideally, I'd like to make a database with the following columns: ID, Name, Category, Link, Thumbnail_Link. So, those would be the ID, name of the game, the category, a link to the game, and a link to the 50x50 thumbnail image respectively. Then, using PHP, I'd like to call the first x number (not sure what it will be yet, let's say 50) and make format it as a grid in the following way: There's the thumbnail image followed by the game name, and they're all a clickable link to the game URL. Is this possible? How would I go about doing this? I've already set up a database for a login module to the site, so each page has already opened a connection to the MySQL database. However, I've only ever done basic PHP for mail forms and am otherwise extremely new to it, and am especially new to MySQL. Could anyone walk me through how to do this or even give me a quick example script to work off of? Thanks, any of your time is greatly appreciated! Hi, I've been trying to figure out a way to create a very large (1000x1000) grid. With each cell being 5x5, so 200 rows and 200 cols. Here is the way I've been doing it: <? $col = 1; while ($col <= 200) { echo("<ul style=\"width: 1000px; height: 5px; border: 0px; margin: 0px; padding: 0px;\">"); $row = 1; while ($row <= 200) { $c1 = "#ffcc00"; $c2 = "#ffff99"; $c3 = "#cfeef6"; $c4 = "#b2ebc5"; $c5 = "#ffffff"; $c6 = "#d7ebff"; $c7 = "#dfceb9"; $c8 = "#b3ccc5"; $number = rand(1,8); $bgcolour = ${"c$number"}; echo("<li style=\"background-color: $bgcolour; width: 5px; height: 5px; float: left; display: inline;\"></li>"); $row = $row + 1; } echo("</ul>"); $col = $col + 1; } ?> It work's, however, as you can imagine it is incredibly slow loading. And browsers such as IE usually end up crashing, even on high end, fast processing PC's, let alone what might happen on an average house hold computer. I've been wondering if there is a more effective method of creating the grid that I am unaware of, I will also be implementing hover boxes (overLib) over each 5x5 cell, which will display dynamic information from a database. And the background color will also be taken from the database and not be decided by the php rand(); like it currently is. So I'm thinking once I start adding more to it, it's going to run even slower than what it is now. I know this is a PHP forum, but if PHP isn't the best answer would anyone think Javascript could make it run smoother? Or is it going to be impossible to create it fast and efficiently no matter what I use? This might be a bit hard to explain! I have a grid, 32x32 which is actually 1024 mySQL rows in a table, you can see the table he http://interbitlotto.com/grid each cell is a row in the database, top left is ID 1, bottom right is id 1024. get it? right well its a battle ship game, and im stuck on the automatic battle ship placement script. I have displayed the generated boats as misses so we can see them. The problem i am having, is that the random number generater chooses a cell too close to the side so the boat ends up wrapping to the other side. I cant think of a way to detect if its going to wrap, if it is then choose another cell... The code below chooses the orientation of the boat, then chooses a random cell... but as you can see, no code for "across" to stop it choosing one too close to the side. Any ideas? Code: [Select] $orientation = rand(1,2); //get random orientation - 1 = down, 2 = across. if ($orientation == 1){ $multiply = 32; //cells till next row $max = 1024 - (32 * $boatlength); //prevents it from choosing a cell too close to the bottom $startcell = rand(1,$max); }else{ $multiply = 1; //across, so next cell $max = 1024; $startcell = rand(1,$max); } Code: [Select] <?php $path = "../assets/tattoos/"; $path2 = "../assets/tattoos-thumbs/"; if(isset($_POST['file']) && is_array($_POST['file'])) { foreach($_POST['file'] as $file) { unlink($path. "/" . $file) or die("Failed to delete file"); unlink($path2. "/" . $file) or die("<meta http-equiv=\"refresh\" content=\"0; url=index.php\" />"); } } ?> <form name="form1" method="post"> <?php $imageDir = "../assets/tattoos/"; $dir_handle = @opendir($path) or die("Unable to open folder"); while (false !== ($file = readdir($dir_handle))) { if($file == "index.php") continue; if($file == ".") continue; if($file == "..") continue; echo "<input type='CHECKBOX' name='file[]' value='$file'>"; echo "<img src='../assets/tattoos/$file' style='height:auto;width:8%;' alt='$file'>"; } closedir($dir_handle); ?> <input type="submit" name="Delete" value="Delete"> </form> I have this code, which calls an image directory and adds a checkbox next to it, you check the boxes you wish, hit delete and the pictures are removed from the server. I need them to display in a grid view, like 4 columns by X amount of rows. Any help would be greatly appreciated. After days of agony, I finally figured out a way to display my blog posts masonry style.
However, I now want to find out if I can make it look exactly (or close to) the static design that I had before which is this :
http://pier36nyc.com/events/
How my dynamic masonry looks like right now on my localhost:
http://postimg.org/image/uy5jb4zax/
This is the code for the masonry:
<script> I don't want to use AI, or a primary key to sort the data, as it could create some problems if the items are visited out of order, but I want to sort it always based upon a single element for speed.
I'm creating a table that will be populated (built), when it's corresponding entry doesn't exist, how do I get it sorted out if someone visits 2, then 7 before they visit 5 to read what's there? It's not a 2d number line, but a 3d number grid.
