Any ideas?

  • PNG composition using GD and PHP

    - by Dominic
    I am trying to take a rectangular png and add depth using GD by duplicating the background and moving it down 1 pixel and right 1 pixel. I am trying to preserve a transparent background as well. I am having a bunch of trouble with preserving the transparency. Any help would be greatly appreciated. Thanks! $obj = imagecreatefrompng('rectangle.png'); $depth = 5; $obj_width = imagesx($obj); $obj_height = imagesy($obj); imagesavealpha($obj, true); for($i=1;$i<=$depth;$i++){ $layer = imagecreatefrompng('rectangle.png'); imagealphablending( $layer, false ); imagesavealpha($layer, true); $new_obj = imagecreatetruecolor($obj_width+$i,$obj_height+$i); $new_obj_width = imagesx($new_obj); $new_obj_height = imagesy($new_obj); imagealphablending( $new_obj, false ); imagesavealpha($new_obj, true); $trans_color = imagecolorallocatealpha($new_obj, 0, 0, 0, 127); imagefill($new_obj, 0, 0, $trans_color); imagecopyresampled($new_obj, $layer, $i, $i, 0, 0, $obj_width, $obj_height, $obj_width, $obj_height); //imagesavealpha($new_obj, true); //imagesavealpha($obj, true); } header ("Content-type: image/png"); imagepng($new_obj); imagedestroy($new_obj);

  • PHP: Doctrine: order joined records

    - by Sebastian Bechtel
    Hi, I'm new to doctrine: I have a problem with the sorting of joined records. A sample. I've got an Article model which is associated with a Source model in 1 <- n. The source model has a property called 'position' with an integer value. Now I want to fetch an article with it's sources orderes by the position. My DQL looks like this: $q = Doctrine_Query::create() ->select('a.title, s.content') ->from('Article a') ->leftJoin('a.Source s') ->where('a.id = ?') ->orderBy('s.position'); The result doesn't change if I edit the position. Best regards, Sebastian

  • Calendar Day View in PHP

    - by JamesArmes
    I'm working on adding a day view option to an existing calendar solution. Like many people implementing their own calendars, I am trying to model Google Calendars. They have an excellent calendar solution and their day view provides a lot of flexibility. For most part, the implementation is going well; however, I'm having issues when it comes to conflicting events. Essentially, I want the events to share the same space, side by side. Events that start at the same time should have the longest event first. In the example data set I'm working with, I have four events: A: 10:30 - 11:30 B: 13:30 - 14:30 C: 10:30 - 11:00 D: 10:45 - 14:00 I can handle A, C, and D just fine, the problem comes with D. A should be left of C which should be left of D; each taking one third of the width (it's fixed width so I can do simple math to figure that out). The problem is that B should be under A and C, to the left of D. Ideally, B would take up the same amount of space as A and C (two thirds width), but I would even settle for it only taking up only one third width. My array of events looks similar to the following: $events = array( '1030' => array( 'uniqueID1' => array( 'start_time' => '1030', 'end_time' => '1130', ), 'uniqueID2' => array( 'start_time' => '1030', 'end_time' => '1100', ), ), '1045' => array( 'uniqueID3' => array( 'start_time' => '1045', 'end_time' => '1400', ), ), '1330' => array( 'uniqueID3' => array( 'start_time' => '1330', 'end_time' => '1430', ), ), ); My plan is to add some indexes to each event that include how many events it conflicts with (so I can calculate the width) and which position in that series it should be (so I can calculate the left value). However, that doesn't help the B. I'm thinking I might need an algorithm that uses some basic geometry and matrices, but I'm not sure where to begin. Any help is greatly appreciated.

  • PHP: Three item validation comparison

    - by DavidYell
    I have 3 featured product panels on the homepage, and I'm writing a CMS page for it. I'm trying to validate the items. They are selected via three <select> elements, featured1, featured2 and featured3. The default is <option value="0" selected>Select an element</option> I need to validate the $_POST to ensure that the user hasn't selected the same product for more than one of the panels. I have worked out that each $_POST needs to be $_POST['featuredN'] > 0 but I can't seem to find a logical way of processing the 7 potential outcomes. Using a logic table, where 1 is a set value. 1 2 3 ------- 0 0 0 1 1 1 1 0 0 0 1 0 0 0 1 1 1 0 0 1 1 If an item is 0, then I will not update it, but I want the user to be able to update a single item if needs be. I cannot find a logical way to see if the item is not 0, and then compare it to another item if that also is not 0. So far my colleague suggested, adding up the values. Which works to see if condition 1 0 0 0 is not met. I have a vague feeling that some form of recursive function might be in order, but I can't quite get my brain to help me on this one! So to the collective brain! :)

    I've a simple question about multi-dim array, I want to remove any redundent element let's say in my case, [serviceMethod] => PL is coming 2 times, I want to search 'PL' with respect of [APIPriceTax] if an element has a lower price I want to keep it and remove the other one in array Array ( [0] => Array ( [carrierIDs] => 150 [serviceMethod] => CP [APIPriceTax] => 30.63 [APIPriceWithOutTax] 28.32 [APIServiceName] => Xpresspost USA [APIExpectedTransitDay] => 2 ) [1] => Array ( [carrierIDs] => 155 [serviceMethod] => PL [APIPriceTax] => 84.13 [APIPriceWithOutTax] => 73.8 [APIServiceName] => PurolatorExpressU.S. [APIExpectedTransitDay] => 1 ) [2] => Array ( [carrierIDs] => 164 [serviceMethod] => PL [APIPriceTax] => 25.48 [APIPriceWithOutTax] => 22.35 [APIServiceName] => PurolatorGroundU.S. [APIExpectedTransitDay] => 3 ) ) This is my pseudo code: Where $carrierAddedToList is the actual array $newCarrierAry = function($carrierAddedToList) { $newArray = array(); foreach($carrierAddedToList as $cV => $cK) { if( !in_array($cK['serviceMethod'],$newArray) ) { array_push($newArray, $cK['serviceMethod']); } } return $newArray; } ; print_r($newCarrierAry($carrierAddedToList));

  • php - using file() incrementally?

    - by NeedBeerStat
    I'm not sure if this is possible, I've been googling for a solution... But, essentially, I have a very large file, the lines of which I want to store in an array. Thus, I'm using file(), but is there a way to do that in batches? So that every,say, 100 lines it creates, it "pauses"? I think there's likely to be something I can do with a foreach loop or something, but I'm not sure that I'm thinking about it the right way... Like $i=0; $j=0; $throttle=100; foreach($files as $k => $v) { if($i < $j+$throttle && $i > $j) { $lines[] = file($v); //Do some other stuff, like importing into a db } $i++; $j++; } But, I think that won't really work because $i & $j will always be equal... Anyway, feeling muddled... Can someone help me think a lil' clearer?

  • php $_SESSION[document_root] too far down the tree

    - by Idealflip
    Hi, I have multiple sub-domains within the document_root. And multiple folders/classes within those sub-domain folders. I need something that will help me with my include_once paths, but $_SESSION[DOCUMENT_ROOT] goes too far down. And if I were to use this, and transfer the website folder later, all my include_once paths will/might break. Hope my question is clear... Any recommendations?

  • PHP MySQL Syntax Error 'You have an error in your SQL syntax'

    - by Alec
    I cannot figure out the issue with my code here. I am trying to take info from the table, then subtract 1 second from Current_Time which looks like '2:00'. The problem is, I get: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Current_Time) VALUES('22')' at line 1" I don't even understand where it gets 22 from. Thanks, I really appreciate it. if (isset($_GET['id']) && isset($_GET['time'])) { mysql_select_db("aleckaza_pennyauction", $connection); $query = "SELECT Current_Time FROM Live_Auctions WHERE ID='1'"; $results = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_array($results)) { $newTime = $row['Current_Time'] - 1; $query = "INSERT INTO Live_Auctions(Current_Time) VALUES('".$newTime."')"; $results = mysql_query($query) or die(mysql_error()); } }

    Hello Everyone, So I have my upload script working just fine, but now it's a matter of making it look the way I want for my layout. <input type="file" name="userfile" id="userfile"/> This obviously shows a textbox with a Choose File button.

I do NOT want the filename textbox to show. Basic steps outlined below. User clicks on image button to upload their file User selects file jQuery shows a div with more fields User clicks submit and file is uploaded

  • PHP variable equals true no matter what the value, even 0

    - by kaigoh
    This is the var_dump: object(stdClass)#27 (8) { ["SETTING_ID"]=> string(2) "25" ["SETTING_SOURCE"]=> string(2) "XV" ["SETTING_FLEET"]=> string(3) "313" ["SETTING_EXAM"]=> string(1) "A" ["SETTING_HIDE"]=> string(1) "0" ["SETTING_THRESHOLD"]=> string(1) "0" ["SETTING_COUNT"]=> string(8) "POSITIVE" ["SETTING_USAGE"]=> string(7) "MILEAGE" } The variable I am testing is SETTING_HIDE. This is being pulled from MySQL using the Code igniter framework. I don't know if it is just me being thick after a rather long day at work or what, but no matter what value the variable holds, any if statement made against it returns true, even when typecast as a boolean or a direct string comparison, ie. == "0" or == "1". Anyone with a fresh pair of eyes care to make me feel silly!?! :) Just to clarify: Have tried the following: if($examSetting->SETTING_HIDE == "1") { $showOnABC = "checked=\"checked\""; } if((bool)$examSetting->SETTING_HIDE) { $showOnABC = "checked=\"checked\""; } if($examSetting->SETTING_COUNT == "POSITIVE") further on in my code works perfectly.

  • PHP Extract Values From One String Based on a Pattern Defined in Another

    - by ironkeith
    I have two strings: $first = '/this/is/a/string'; $second = '/this/:param1/a/:param2'; And I'm trying to get this: $params = array('param1' => 'is', 'param2' => 'string'); But getting from point a to b is proving more than my tired brain can handle at the moment. Anything starting with a ':' in the second string defines a variable name/position. There can be any number of variables in $second which need to be extracted from $first. Segments are separated by a '/'. Thanks.
