    Posted

    i have a array calles $articles, this is a part of it:

     

    Array
(
    [1335905082] => Array
        (
            [channel] => 
            [title] => SimpleXMLElement Object
                (
                    [0] => NEW PRODUCT – Blue 7-segment clock display – 0.56 digit height
                )

            [link] => SimpleXMLElement Object
                (
                    [0] => http://www.adafruit.com/blog/2012/05/01/new-product-blue-7-segment-clock-display-0-56-digit-height/
                )

                    [0] => Tue, 01 May 2012 20:44:42 +0000
                )

            [timestamp] => 1335905082
            [description] => NEW PRODUCT – Blue 7-segment clock display – 0.56 digit height. Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display.

            [isPermaLink] => SimpleXMLElement Object
                (
                    [0] => false
                )

            [creator] => adafruit

     

    when i use:

     

    foreach($articles as $article) {
$title = $article['title'][0];
echo '<pre>';
print_r($title);
echo '</pre>';
}

     

    i get stuff like:

     

    SimpleXMLElement Object

    (

        [0] => NEW PRODUCT – Yellow 7-segment clock display – 0.56 digit height

    )

    SimpleXMLElement Object

    (

        [0] => NEW PRODUCT – Dual H-Bridge Motor Driver for DC or Steppers – 600mA – L293D

    )

     

    But i expected:

     

    NEW PRODUCT – Yellow 7-segment clock display – 0.56 digit height

    NEW PRODUCT – Dual H-Bridge Motor Driver for DC or Steppers – 600mA – L293D

    I try to get the content from

    some stuff is like this:

    ]]>

     

    no idea if that matters.

    Atm i have this:

     

    $xml =  getFileContents("http://www.adafruit.com/blog/feed/");
$xmlTree = new SimpleXMLElement($xml);

//foreach()
//print_r2($xmlTree);

for($i = count($xmlTree->channel->item)-1; $i >= 0; $i--) {

$item = $xmlTree->channel->item[$i];
print_r2($item);
//print_r2($item->category);

//$category = $item->category;
//print_r2($category);


}

     

    it prints stuff like:

    SimpleXMLElement Object

        [title] => New videos – Customer service, shipping, order status and more…

        [description] => SimpleXMLElement Object

            (

            )

     

    )

     

    category and description are empty, how can i get that content?

     

    print_r2 is just this:

     

    function print_r2($val){
echo "<pre>";
print_r($val);
echo "</pre>";
}

    problem with LEFT JOIN

    in MySQL Help

    Posted

    I have a database with articles, i also have a database with ratings.

    The ratings.articleId is for articles.id, in example if ratings.articleId = 50 then it belongs to the one where articles.id = 50;

     

    $t is a number

     

    $query = "SELECT articles.id, articles.headline ratings.rating FROM articles ";
$query .= "LEFT JOIN ratings ON (ratings.articleId=articles.id) ";
$query .= "WHERE articles.id>'$t'";

     

    this is the error atm:

    Query failed: 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 '.rating FROM articles LEFT JOIN ratings ON (ratings.articleId=articles.id) WHERE' at line 1

    fill aray with keys and values

    atm i have this in a function:

     

    $returnInfo = array();

$returnInfo["totalWords"] = $totalWords;
$returnInfo["uniqueWords"] = count($uniqueWords);
$returnInfo["positiveWords"] = $positiveWords;
$returnInfo["negativeWords"] = $negativeWords;
$returnInfo["rating"] = $mappedrating;

return $returnInfo;

     

    If i recursive print it it says Array instand of my expected values.

     

    p.s., i have found examples where the array get's created in 1 line with all there values but i prefer not to do that since it will be a very long line.

    timestamp is 0000-00-00 00:00:00 in database

    thanks, the insert works now.

     

    One more thing, i have a function to check if something is inserted:

     

    function timeStampExists($pubDate) {
//$query = "SELECT * FROM articles WHERE timestamp='$timestamp'"; 
$query = "SELECT * FROM articles WHERE timestamp='STR_TO_DATE('$pubDate', '%a, %d %b %Y %T')'"; 
$res = mysql_query($query); 
if (mysql_num_rows($res) > 0) { 
	return true;
} else {
	return false;
} 
}

     

    I only get this error:

    Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /

    on this line:

     

    if (mysql_num_rows($res) > 0) {

    $pubDate:

     

    Thu, 01 Dec 2011 20:22:52 +0100

     

    $timestamp = strtotime($pubDate);

    gives:

    1322767372

     

    so that seems to be ok.

    Also i get no query errors for inserting, only all values it inserts are  0000-00-00 00:00:00

     

    I tried different setting in my database, this was the last:

     

    # Kolom       Type               Collatie Attributen                                         Null     Standaardwaarde                   Extra

    5 timestamp timestamp         on update CURRENT_TIMESTAMP Nee       CURRENT_TIMESTAMP ON      UPDATE CURRENT_TIMESTAMP

    I want to get the url in the [@attributes]

    Atm i get the title like this

     

    foreach ($xmlTree->channel->item as $item) {
    echo '<p>'.$item->title.'</p>';
}

     

    i tried this

        $imageUrl = $item->enclosure->@attributes->url;
    print_r2($imageUrl);

     

    but then i get this error:

    Parse error: syntax error, unexpected '@', expecting T_STRING or T_VARIABLE or '{' or '$' in /

    image in a rectangle

    in HTML Help

    Posted

    thanks but that's not what i meant, i should have been more clear.

     

    I want to show multiple images in columns:

     

    [ ] [ ] [ ] [ ]

    [ ] [ ] [ ] [ ]

    [ ] [ ] [ ] [ ]

    [ ] [ ] [ ] [ ]

     

    And therefore a image like this [    ] should be a rectangle so that's why i want to center them since often there is the more important content of a image.

    Fatal error: Using $this when not in object context

    in PHP Coding Help

    Posted

    First i will show the code that activates the error:

     

    		if($current_host != null) {
		print_r2("1");
		print_r2($current_host);
		print_r2($current_foundResult);
		print_r2("2");
		$current_host::addFoundResult($current_foundResult);
	}

     

    this is the output:

     

    1

     

    Host Object

    (

        [hostname] => www.google.nl

        [foundResults] => Array

            (

            )

     

    )

     

    FoundResult Object

    (

        =>

        [title] =>

        [visits] =>

    )

     

    2

     

     

    Fatal error: Using $this when not in object context in ~~~~~~~~~~~~~ on line 385

     

    the error comes from this line:

    $this->foundResults[] = $foundResult;

     

     

    class Host {

public $hostname;
public $foundResults;

public function __construct($hostname) {
	$this->hostname = $hostname;
	$this->foundResults = array();
}

public function addFoundResult($foundResult) {
	$this->foundResults[] = $foundResult;
}
}

     

    what i don't get about it is that both the Host Object and the FoundResult Object exist...
