wkhtmltopdf - cannot convert local file

- by user522962

I just downloaded version 10.0 for opensuse v. 11.3. I can convert a webpage (ie www.google.com) using it but cannot convert a local file. I grant all permissions on the file (& i've even tried running under sudo to no avail). This is the error: "Loading pages (1/6) Error: Failed loading page file:///file.html". The file exists but wkhtmltopdf refuses to load it. I even tried version 9.9 w/ the same result What am I missing?

pass data from popup to parent

- by user522962

I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that? Here's my parent: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" backgroundColor="green" width="50%" height="100%" xmlns:local="*" > <fx:Script> <![CDATA[ import pup; import mx.managers.PopUpManager; public function showPup(evt:MouseEvent):void { var ttlWndw:pup = PopUpManager.createPopUp(this, pup, true) as pup; PopUpManager.centerPopUp(ttlWndw); } ]]> </fx:Script> <mx:VBox> <local:pup id="pupLove" visible="false" includeInLayout="false" /> <s:Button click="showPup(event);" label="launch Pup" /> <mx:Text id="Ptest" color="black" text="from Parent:{pupLove.dg.length}" /> </mx:VBox> </s:Application> And a popup child called 'pup.mxml': <?xml version="1.0" encoding="utf-8"?> <s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"> <fx:Script> <![CDATA[ public function init():void{ // send php call } import mx.events.CloseEvent; import mx.managers.PopUpManager; private function removePup(evt:Event):void { PopUpManager.removePopUp(this); } ]]> </fx:Script> <fx:Declarations> <s:ArrayCollection id="dg"> </s:ArrayCollection> </fx:Declarations> <s:TitleWindow width="100%" height="100%" close="removePup(event)"> <mx:VBox> <mx:Text id="test" color="red" text="from Child:{dg.length}" /> <s:Button label="add Items" click="dg.addItem({id:'cat'})" /> </mx:VBox> </s:TitleWindow> </s:Group> UPDATE: I guess my question can be more easily stated as: "is there a way to call a child's function from the parent without actually loading the child?"

mysql stored routine vs. mysql-alternative?

- by user522962

We are using a mysql database w/ about 150,000 records (names) total. Our searches on the 'names' field is done through an autocomplete function in php. We have the table indexed but still feel that the searching is a bit sluggish (a few full seconds vs. something like Google Finance w/ near-instant response). We came up w/ 2 possibilities, but wanted to get more insight: Can we create a bunch (many thousands or more) of stored procedures to speed up searches, or will creating that many stored procedures bog-down the db? Is there a faster alternative to mysql for "select" statements (speed on inserting & updating rows isn't too important so we can sacrifice that, if necessary). I've vaguely heard of BigTable & others that don't support JOIN statements....we need JOIN statements for some of our other queries we do. thx

indexing question

- by user522962

I have a table w/ 3 columns: name, phone, date. I have 3 indexes: 1 on phone, 1 on date and 1 on phone and date. I have the following statement: SELECT * FROM ( SELECT * FROM people WHERE phone IS NOT NULL ORDER BY date DESC) as t GROUP BY phone Basically, I want to get all unique phone numbers ordered by date. This table has about 2.5 million rows but takes forever to execute....are my indexes right? UPDATE: My EXPLAIN statement comes back with 2 rows: 1 for primary table and 1 for derived table. It says I am using temporary and using filesort for my primary table. For my derived table, it says my possible keys are (phone), and (phone, date) but it is using filesort.

DateTime object is blank

- by user522962

I am trying to convert a date to a DateTime Object. My code works fine on my localhost (php version 5.3) but returns a blank DateTime object on my remote server (php version 5.2.14). Am I missing something really obvious? <?php $d = '2010-01-01'; $n = new DateTime ( $d ); print_r($n); ?> // result on localhost: DateTime Object ( [date] => 2010-01-01 00:00:00 [timezone_type] => 3 [timezone] => UTC ) // result on remotehost: DateTime Object ( ) // is blank

object-oriented question

- by user522962

I am attempting to put all my database connections in 1 php file, rather than in each of my individual php pages. I have the following: //conn.php: <?php class conn { var $username = "name"; var $password = "password"; var $server = "localhost"; var $port = "3306"; var $databasename = "db"; var $tablename = "tablename"; var $connection; public function getConnected() { $this->connection = mysqli_connect( $this->server, $this->username, $this->password, $this->databasename, $this->port ); } } ?> // file.php: <?php require_once("conn.php"); class myClass{ public function con() { $conn = new conn(); $conn->getConnected(); } public function myF() { $stmt = mysqli_prepare($conn->connection, "SELECT * FROM $conn->tablename"); mysqli_stmt_execute($stmt); } } ?> I then call this as follows: $myNew = new myClass(); $myNew-con(); $myNew-myF(); When I call this, I get the following error: Undefined property: myClass::$connection What am I doing wrong?
