Hi, I have a database where I store times with the Now(); function.

What I want is:
When the viewer looks at the post, instead of it saying: Posted: 2010-11-14 19:08:14,
I want it to say posted: x hours ago, Posted: x days ago, etc.

Any help with this would be appreciated!

Okay, I have a healing spell that allows people to regain stats when it's cast. But, how do I limit it so that they can't go over their maxhp?

Here's what I have so far:


$db->execute("UPDATE `users` SET `hp`=?, `mp`=?, `energy`=? WHERE `id`=?", array($player->hp + $healspell, $player->mp - $spell['mp'], $player->energy - $spell['energy'], $player->id));


What do I need to do in this to tell it to limit it to the maxhp but never going over it? $healspell is a random number, so it is quite possible to go over the maxhp at the moment.

Thank you!

Hey quick question on my homepage there is a featured content section, which is populated from my DB some of the posts are really long so I would like to limit the amount of text. how can I do this?  also is there a way to make sure if does not cut a word in half?

thanks

If I knew what to call it I could have searched it.  So I will just explain.

I have a form that is pulling from a database to build the following.
echo <input name='$row[id]' type='text' id='$row[id]' size=2>;

This will build a page that has this
<input name='22' type='text' id='22' size=2>
<input name='54' type='text' id='54' size=2>

This part works great.  The problem is when I try to add it to the database.  How can I insert variables that I don't know the names of?  They will be something like $_POST[22]   $_POST[54] and so on.  I hope someone can understand my jibberish.

I am sure there is a WAY better way to do this.

Hi All,

Im new to this forum but think its going to be a regular location for me for quite a while.

Im very very new to php and the guy that was doing code for me is not responding to emails, so i thought id have a go myself...lol
at the moment im going through the trial and error phase while learning.

I have edited some of the code he has put on the site to create a new look.
the original page: http://www.ridersguide.co.uk/county_accommodation.php?county=4;
the one im trying:http://www.ridersguide.co.uk/county_accommodation2.php?county=4;

The new bit is to add a preview of the text for the page.

echo $row[ad_text];
the code above brings up all the text but i only want to show the first 4 or 5 lines. Is this possible in php?

Any help appreciated

I have a field in my database called description. How can I echo out only 500 out of the 2000 max characters?

Like for example:

Code: [Select]
$query = mysql_query("SELECT description FROM `servers` ORDER BY votes DESC LIMIT 5");

If I were to echo out the value of description for the database, how can I only echo out the first 500 characters?

Hi,

I have a function where I want to sort an an array of this type:

0 = {'fruit' => 'banana', 'color' => 'yellow', 'age' => '1', 'weight' => '2', 'brand' => 'dole', 'store' => shaws'}
1 = {'fruit' => 'apple', 'color' => 'red', 'age' => '3', 'weight' => '5', 'brand' => 'fuji', 'store' => 'foodmaster'}
etc etc.

I then want to array_multisort this array with different parameters. One way is to sort by fruit, then color, then brand. The second way by age, then store.

Code: [Select]
//This is how I sort it for my first way
//Let's call the array $rows
function sort($rows) {
foreach($rows as $key => $value) {
        $fruit[$key] = $value['fruit'];
$color[$key] = $value['color'];
$brand[$key] = $value['brand'];
    }

    array_multisort($fruit, SORT_ASC, $color, SORT_ASC, $brand, SORT_ASC $rows);
}
I want to try to reuse this function by passing in the keys that I want to sort with. Like doing sort($rows, array('fruit', 'color', 'brand')), then sort($rows, array('age', 'store')). Is this possible?

         

Hi, i have a folder with thumbnails and original big pictures of the thumbnails, i wanna make it so that the max amount of thumbs that can be displayed on one page would be 3

Code: [Select]
<body>
<div id=head></div>
<div id=main>
<?php include("loadimages.php") ?> //<- here i take all the thumbnails that are in my thumb folder
</div>
<div id=foot></div>
</body>

i have 5 thumbnails, it displays all of them in the "main" div, i wanna add an "Next" and "Previous" buttons, i mean, i want it to show only 3 thumbs at one time, once u click "next" it would remove the first 3 thumbs and load the other 2 thumbnails..

heres a pic maybe it will explain better of what im trying to do..

Hi,

I'm trying to code a page which displays the amount of users currently viewing a page. But how do I decrease the count if a user closes the page?

Thanks

So I wrote this piece of code that for the most part works. The problem is two things. One if I print out say $dir[$i] I get 7 directories back. if I try and store that in an array to later be access by some other function I get up to 24+ C's instead of C:/Path...

Code: [Select]
public function aisis_get_dir_array($dir){

if(!is_array($dir)){
aisis_get_dir($dir);
return;
}

$count = count($dir);
for($i = 0; $i<$count; $i++){
if(!is_dir($dir[$i])){
_e('Specified dir' . $dir[$i] . 'is not a directory.');
}

$this->directory_list = $dir[$i]; //store these

$handler = opendir($dir[$i]);
while($file = readdir($handler)){
if($file != "." && $file != ".."){
$this->files[] = $file;
}
}

}

return $this->files;
}

right under the line: $this->directory_list = $dir[$i]; //store these if You put in echo $dir[$i] you get back directories.
How ever down in this function:

Code: [Select]
public function load_if_extentsion_is_php($dir, $array = false){
$list = array();
$list_dir = array();

if($array == true){
$list = $this->aisis_get_dir_array($dir);
$list_dir = $this->directory_list;
}
else{
$list = $this->aisis_get_dir($dir);
}

$count = count($list);
for($i = 0; $i<$count; $i++){
if($array == true){
$countdir = count($this->directory_list);
for($j = 0; $j<$countdir; $j++){
echo $list_dir[$j];
//echo $list_dir[$j];
//echo $list[$i];
}
}
//if(substr(strrchr($list[$i],'.'),1)=="php"){
//echo $list[$i];
//require_once($dir . $list[$i]);
//}
}

}

echoing out: echo $list_dir[$j]; gets you up to 24+ C's instead of the directories that are stored.

You can view the whole class at  Paste bin - there is an expiry: 12 hours.

Essentially you call load_if_extentsion_is_php($dir, $array = false) pass it an array of directories and set the array part to true.

To Summarize:

If you pass in an array of directories you should get back:

a echoed list of directories
a echoed list of php files belonging in those directories.

Currently you get the later and a series of C's for  the first.

Why?

I am working on php script that takes an input (using html) stores those values in a separate text file. I managed to get that to work. But the thing is I wanted to be able to sort those values alphabetically. Since their are an unspecified amount of inputs I tried using an explode on my output in order to store those values as an array so that I can sort them. Problem is explode makes each input its own separate array instead of one whole array. I figure some type of loop is needed to fix that but I can't figure out how to go about creating it [I'm pretty new to php]. Any advice? Heres my code for my PHP script:

$filename = "ip_collection.txt";
$fileHandle = fopen('ip_collection.txt', 'a+') OR die("can't open file\n");
$ip = $_SERVER['REMOTE_ADDR'];
$name = stripslashes($_POST['lastName'] . ", " . $_POST['firstName']);
$textFromForm = $name. " | " . $ip;
$newtext = $textFromFile . $textFromForm;
$output = explode("\n",$newtext);
sort($output);
foreach($output as $key => $value) {
fwrite($fileHandle, $value."\n");
}
fclose($fileHandle);

if i want to display upcoming events and only want to show the top 3?
