thank you Similar TutorialsCode: [Select] <?php $path = "../assets/tattoos/"; $path2 = "../assets/tattoos-thumbs/"; if(isset($_POST['file']) && is_array($_POST['file'])) { foreach($_POST['file'] as $file) { unlink($path.

I need them to display in a grid view, like 4 columns by X amount of rows. Any help would be greatly appreciated. Hey 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. Hi folks, I am in the middle of creating a CMS as a project. It's going pretty well so far but I am stuck and hoping to get some guidance.

I hope you can help and that I am making sense. Cheers, Dan Edited January 9 by DanEthicalAlright, I looked though the read me's, went over the FAQ's... Think it is time to post...
So, this lump is what I got from going though google and piecing together the bits that looked good.
<?php
$db_host = "****";
$db_user = "****";
$db_pwd = "****";
$database = "****";
$table = "****";
$query = "SELECT * FROM {$table}";
$conn = mysqli_connect($db_host, $db_user, $db_pwd, $database);
$result = mysqli_query($conn,$query) or trigger_error($query . ' - has encountered an error at:<br />' . mysqli_error($conn));
$fields = mysqli_fetch_fields($conn);
$field_count = mysqli_num_fields($conn);
echo '<table border="1" style="width:100%">' . "\n" . '<tr>';
$i = 0;
foreach($fields as $field)
{
if(++$i == 1) {
echo '<th colspan="' . $field_count . '">' . $field->table . '</th></tr><tr>';
}
echo "\n" . '<th>' . $field->name . '</th>';
}
echo '</tr>';
while($row = mysqli_fetch_row($result)) {
echo '<tr><td>' . implode('</td><td>' , $row) . '</td></tr>';
}
echo '</table>';
?>
The goal is to display the table and conditionally format the contents.
Let's forget about the conditional part (thinking if/than but don't know how I'm going to do that yet) and focus on the key problem: displaying the table.
I have tested this code. It works...to a point. it displays the table and its contents but no headers. I know my issue is in line 20 and 22 but I can not for the life of me figure it out. If it is stupidly easy (for you) please remember that I am not a coder. At best I am a scripter when it comes to linux. I am over my head on this stuff.
Thank you all for any help you can give me
Edited by TheAlmightyOS, 18 November 2014 - 03:30 PM. How do I create a coordinate map in php? I created ordered pairs and I want to plot them on a grid. Grid is about 200000x200000.

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. 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. Need help in achieving a data entry grid. I have two tables am_user (idam_user, name) and am_activity (idam_act, act) with the data Data for am_user is 1, John 2, Mary 3, Kate Data for am_activity is 1, Cooking 2, Cleaning 3, Painting I have a third table that stores the role played by each user for the activities. am_role (idam_role, role) 1, Manage 2, Observe 3, Documents I want my User table to be my header, Activity table to my 1st column and Role table to populate the data grid John Mary Kate Cooking Manage Document Observe Cleaning Document null Manage Painting Observe Document Manage By putting two while loops I am able to generate the header and 1st column but I need help in populating the grid in between. Also I want my data entry area (rows and column besides header and 1st column) to have lookup where they can select values from the am_role table. So, John can "Manage" "Painting" tomorrow if he wants to The two while loops are Code: [Select] $query = "select idam_user, Name "; $query .= " from am_user "; $result = mysql_query($query) or die(mysql_error()); // display data in table echo "<center>"; echo "<table>"; echo "<tr>"; echo "<th></th>"; // loop through results of database query, displaying them in the table while($row = mysql_fetch_array( $result )) { // echo out the contents of each row into a table echo '<th>' . $row['name'] . ' '; echo "</th>"; } echo "</tr>"; $query = "select idam_act, act "; $query .= " from am_activity "; $result = mysql_query($query) or die(mysql_error()); // display data in table // loop through results of database query, displaying them in the table while($row = mysql_fetch_array( $result )) { // echo out the contents of each row into a table echo '<tr>'; echo '<td>' . $row['act'] . '</td>'; echo '</tr>'; } // close table> echo "</table>"; echo "</center>"; Please advise if this thought is realistic and how can I achieve it. Thanks in anticipation. 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? 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 :

How my dynamic masonry looks like right now on my localhost:

This is the code for the masonry:
<script> 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); } 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.

This topic has been moved to HTML Help. http://www.phpfreaks.com/forums/index.php?topic=327455.0 Hello everyone, For two weeks now, I'm trying to get this database connection in my query. Can someone give me a solution and tell me what I've done wrong? Am I overlooking something? <?php class Mysql{ public function connect(){ $mysqli = new mysqli('localhost','root','','login'); } } class Query extends Mysql{ public function runQuery(){ $this->result = parent::connect()->query("select bla bla from bla bla"); } } $query = new Query; $query->runQuery(); ?> When running the following code i get the error: Call to undefined method mysqli::errno() the code: $conn = new mysqli(HOST, USER, PASSWORD, DATABASE); if ($conn->errno() !== 0) { $msg = $conn->error(); throw new connErrorException($msg, 'Connect'); } I am fairly new to classes but as i understand it this should be correct. I am using mysql 5.1 so mysqli is on by default. I have even checked the php ini and everything looks fine there in respect to this. Any advice? I dont know whether the statement is correct.....i just tried it.....and it didn't work. $stmt->bind_param('ssiiiss',$_POST['name'],$_POST['email'],$_POST['d'],$_POST['m'],$_POST['y'],$_POST['add'],$_POST['phone']); here my first two values are strings and next 2 tiny int's next is int and last 2 again strings. |
