PHP - Module Question
I can't seem to find a tutorial on basics of making a module based php system. Like how to fetch and execute the module.

This is a node voting module I created and it has a slight problem that I cannot figure out. It's supposed to be a simple 'Vote Up' or 'Vote Down' feature. You click 'Vote Up' and one appears in your vote tally. You click 'Vote Down' and your original vote tally is subtracted by one back down to zero. When it goes back to zero, it gets stuck there. It stays on zero no matter if I choose 'Vote Up' or 'Vote Down' again. There's something that's happening when I move my vote tally back down to zero. Maybe something isn't setup correctly with the $current_votes variable. I don't know. I've been at this for hours. Here's the code: <?php function bonnier_vote_perm() { return array('vote on content'); } function bonnier_vote_menu() { $items = array(); $items['vote'] = array( 'title' => 'vote', 'page callback' => 'bonnier_vote_vote', 'access arguments' => array('vote on content'), 'type' => MENU_CALLBACK, ); return $items; } function bonnier_vote_vote() { $nid = $_REQUEST['nid']; $value = $_REQUEST['votes']; $current_votes = db_result(db_query("SELECT votes FROM bonnier_vote WHERE nid = $nid")); if ($current_votes) { $new_votes = $current_votes + $value; db_query("UPDATE bonnier_vote SET votes = $new_votes WHERE nid = $nid"); } else { db_query("INSERT INTO bonnier_vote (nid, votes) VALUES ($nid, $value)"); } drupal_set_message('Your vote has been recorded'); drupal_goto('node/'.$nid); } function bonnier_vote_nodeapi(&$node, $op, $teaser = null, $page = null) { if ($op == 'view' && !$teaser) { $votes = db_result(db_query("SELECT votes FROM bonnier_vote WHERE nid = {$node->nid}")); if (!$votes) { $votes = 0; } $widget = '<div>'; $widget .= l('Vote Up', 'vote', array('query' => array('nid' => $node->nid, 'votes' => 1))); $widget .= ' '; $widget .= l('Vote Down', 'vote', array('query' => array('nid' => $node->nid, 'value' => -1))); $widget .= ' '; $widget .= 'Sco '. $votes; $widget .= '</div>'; $node->content['vote_widget'] = array( '#value' => $widget, '#weight' => -10, ); } } Any bit of advice would be much appreciated. Hello,
First time asking technical question in a forum so I beg pardon for errors.
I have a third party blog module installed on opencart. The original coder helped me to fix some bugs, but he is not answering anymore to emails.
I would like to add a simple pagination to the "latest articles" part, because at the moment the website display the exact number declared in "article limit" and does not show pagination if articles shown are less than the total.
the code from "article_by_type.php" line 85 is the following:
/*recent_article*/
if ($setting['article_type']=='recent_article') {
$data = array(
'sort' => 'p.date_added',
'order' => 'DESC',
'start' => 0,
'limit' => $article_limit
);
$articles = $this->model_news_article->getArticles($data);
}
another file "article_list.php" at line 88 and 214 already have pagination:
$this->data['article_ajax_load'] = $this->getArticle($article_category_id,$page,$limit,$description_limit);can anyone help add pagination to "article_by_type.php" or adapt the existing pagination code to it ?

I want to move it to the position illustrated by the arrow, and I want to increase it's height so it fills the space but leaving a border. There is no module in the position that I can use, so I have to adjust the html coding (I presume). Can anyone help me with this? I have searched for help and I don't even know which file I need to change - whether it is the css or the html. Cheers, James. I have problem with PHP module for meta search engine, this module takes image results from google and sends it to meta search engine as a result. But it is not working, there is a problem in PHP code witch i have no idea how to find and fix. Code: [Select] <?php class image_google { function image_google() { $this->profile = array( 'site_name' => 'Google', 'site_url' => 'http://www.google.com', 'request_url' => 'http://www.google.com/search?q=$e_qry_str&site=images&tab=wi&start='.(20*($_REQUEST['d']-1)), ); } function parse_results(&$output) { #echo $output; # debug $results = array(); if(preg_match_all('{imgurl=(.*?)&imgrefurl=(.*?)&}is',html_compress(remove_code($output)),$matches,PREG_SET_ORDER)) { $last_match = ''; foreach($matches as $r) { $result = array( 'real_url' => html_decode($r[2]), 'follow_url' => html_decode($r[1]), 'image_url' => html_decode($r[1]), 'title' => html_decode($r[1]), 'description' => html_decode($r[1]), ); array_push($results,$result); $last_match = &$r[0]; } if($last_match) { $offset = strpos($output,$last_match)+strlen($last_match); $output = substr($output,$offset); } } #var_export($results); # debug return $results; } } ?> Is there a code library out there that can read the exif data from image files, without the use of the php exif extension? I have a Windows hosting package and am noticing that several hosts don't (and won't) enable the exif extension for PHP for some reason. I need Windows for one of my sites which requires MS SQL access, so I can't use a Unix/Linux host because of that. But all of them support PHP on Windows.
Suggestions?
when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement. Here is code I was experimenting with: <html> <body> <form action="" name="test" method='POST'> <input type="radio" id="sex" value=1 checked><label>Male</label> <input type="radio" id="sex" value=2><label>Femaleale</label> <?php $result = "value"; if ($result == 2) echo "<input type='int' id='gradYear' size='3' required>"; else echo "Not a female!" ?> <input type="submit" value="GO"> </form> </body> </html> The code passes debug, however, Not a Female is displayed. My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped. Thanks for the assis in advance. i am looking for a way to write a php script to pull information from a html table and put that information in to the databases does any one have any idea who to do this Hello, I have a 'strange' situtation. I have this string "Who Am I" that will be used as an header (site for a client) but the design shows that the word "Who" and the words "Am I" are in 2 different colors, in HTML this is a quick fix, but in PHP? What I was thinking was explode the string and fetch the first element put it in a var en then concat the 2 others. But what if the title is more then 3 elements after exploding? It needs to be more dynamic, but I don't know how to do it. Does anyone have an idea? are there any php functions that are best used when testing to see if a server is busy or not? and if the server is busy then display a "server is busy" message in the php script? hello all, i am having a for each problem. im trying to get two post fields using the foreach function. here is what i have in my form.php: Code: [Select] <?php foreach($_POST['staff'] as $value) { echo "$value - <br />"; } ?> the name of the the fields coming in are Code: [Select] name='staff[]' and the second one is name='descr[]' fields += 1; Major breakthrough. utf8_encode() allows me to view utf-8 characters in the browser. Therefore, my source data file must be ISO-8859-1 encoded text, right? Am I understanding this correctly?
<?php
//mb_internal_encoding("UTF-8");
header('Content-type: text/html; charset=utf-8');
$file = fopen('some_csv_file_created_by_excel.csv', "r");
ob_start();
while (($spec = fgetcsv($file, 100000, ",")) !== FALSE){
echo($spec[0].' '.utf8_encode($spec[0]).'<br>');
}
$string=ob_get_clean();
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>utf</title>
</head>
<body>
<p><?php echo($string);?></p>
</body>
</html>
Edited by NotionCommotion, 11 January 2015 - 08:22 PM. Code: [Select] <?php if ($News_1_Status=="Y") echo <div class="newstitle" align="left"><?php echo $News_1_Date;?> <a href="<?php echo $News_1_URL;?>"><?php echo $News_1_Name;?></a></div><br>; else echo "Have a nice day!"; ?> how do i get the above script working any clue? I am trying something simple, creating some horses and making them race using OOP, creating them is easy, how can i find out which one "won" based on the highest total. Here is what i got so far Code: [Select] <?php class Horse { public $strength; public $speed; public $agility; public function create($name,$age,$odds){ $this->name=$name; $this->odds=$odds; $this->strength=(rand(50,200) * $this->odds - $this->age); $this->speed=(rand(100,400) * $this->odds - $this->age); $this->agility=(rand(150,250) * $this->odds - $this->age); $all=array(0=>"$this->strength",1=>"$this->speed",2=>"$this->agility"); echo "<b>$this->name</b> has a strength of <b>$this->strength</b>, a speed of <b>$this->speed</b> and agility at <b>$this->agility</b>. --- <b>".array_sum($all)."</b><br>"; } } $mix=rand(2,6); $a=new Horse; $a->create("Dave", 2, $mix); $a->create("Dude", 3, $mix); $a->create("Evan", 3, $mix); $a->create("Jill", 15, $mix); $a->create("Flex", 10, $mix); ?> I cant figure out a way to find out who had the highest total, i would love to know what i am doing wrong. i am trying to understand, how a site like ebay can display content and be case insensitive? for example: The original url: http://www.ebay.co.uk/itm/Toshiba-Satellite-C50-AMD-E-Series-1-4GHz-Dual-Core-15-6-Inch-500GB-2GB-Laptop/151458954958the above works fine and go to the intended page. user editing the browser url into lowercase : http://www.ebay.co.uk/itm/toshiba-satellite-c50-amd-e-series-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958random uppercase and lowercase. http://www.ebay.co.uk/itm/toshiba-sateLLite-c50-aMd-e-sERIes-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958both the urls above also work fine and go to the intended page. How can such a thing can work? it is supposed to throw an error such as page not found and the like? any thoughts welcome. Im not new to php but I am trying to think if this possible. I want to write a php script that creates a div inside a div until lets say 10 divs are created. I have been trying do while statements but them seem to place them underneth each other not within. I want <div id=one"> <div id=two"> <div id=three"> </div> </div> </div> Only thing I can create is <div id=one"></div> <div id=two"></div> <div id=three"></div> Like I said I dont even know if this is possible or if I am just retarded and can't think of a way to do it but it would be nice to see what others have to say about it. |
