PHP - Set Property In Object Of Object Of Object
I have a Soup object in a Bowl object in a Microwave object.
The Microwave object has the methods: receiveItem(Bowl $b) cookItem(???) I want the Microwave to be able to set the Soup->temperature but I'm not how to do that? Make sense? TomTees Similar TutorialsHey all, I want to have an object that has a property which is an object containing instances of other objects. I try this: Code: [Select] class Blog extends Posts { public $has_posts; public function __construct($a,$b,$c){ $has_posts = (object) array_merge((array) $a, (array) $b, (array) $c); } } class Posts { public $b; public function __construct($b){ $this->b = $b; } } $post1 = new Posts(1); $post2 = new Posts(2); $post3 = new Posts(3); $blog = new Blog($post1,$post2,$post3); var_dump($blog->has_posts); //null foreach($blog->has_posts as $post){ //Invalid argument supplied for foreach() echo $post->b; } But as you see, has_posts is null, not an object containing other objects. Thanks for response. Hi all, I have a script which I coded not long ago which works fine but there is one error which says: Notice: Trying to get property of non-object in /home/www/***-*****.com/hts.php on line 374 I carnt see why its showing the error. $fetch2=mysql_query("SELECT crew FROM users WHERE username='$username'") or die (mysql_error()); $fetch1 = mysql_fetch_object($fetch2); $crewrep1=mysql_query("SELECT * FROM crews WHERE name='$fetch1->crew'") or die (mysql_error()); $crewrep = mysql_fetch_object($crewrep1); $result = $rep + $reps; $result55 = $crewrep->rep + $reps; // Line 374 Can anyone else see why its showing the error? Thanks for your help. I've been getting this error message: Trying to get property of non-object in /application/controllers/index.php on line 37 Here is line 37 $this->view->title = $pageInfo[0]->title; any help would be much appreciated. Keep getting this error from line 19 (Notice: Trying to get property of non-object in /clientdata/zeus-dynamic-1/s/o/blahblah/www/tyson/onion.php on line 18)... have no idea how to get rid of it. Do I have to use isset? If so.. where??? (obviously I've replaced site address with website) Code: [Select] include('simple_html_dom.php'); $story = array(); getArticles('website'); function getArticles($page) { global $story, $desc, $read; $html = new simple_html_dom(); $html->load_file($page); $items = $html->find('div[id=story_content]'); foreach($items as $post) { $story[] = array($post->children(0)->plaintext, $post->children(2)->next_sibling()->innertext, $post->children(4)->innertext); } } $i = 0; foreach($story as $item) { $syurl = str_replace('href="', 'href="http://website', $item[2]); echo '<p class="storytitle">' . $item[0] . '</p>'; echo '<p class="storyexcerpt">' . $item[1] . '</p>'; echo '<p class="storyread">' . $syurl . '</p>'; if (++$i == 3) break; } Any ideas? This line is causing the issue: $story[] = array($post->children(0)->plaintext, $post->children(2)->next_sibling()->innertext, $post->children(4)->innertext); Likewise, it does post the 3 storys below the 2 error lines...?

Hello, I'm currently in the process of trying to learn php. I've been working on an issue with something I am trying to code from a book I purchased "PHP and MySQL Web Development 5th Ed." by Luke Welling and Laura Thomson. So far the book has been great, but I'm trying to figure out using MySQL and php. When I try to run this particular script for a query for a book store, I get the error: Notice: Trying to get property of non-object in C:\php-book\ch11\results.php on line 37. This is the code: Code: [Select] $query = "select * from books where ".$searchtype."like '%".$searchterm."%'"; $result = $db->query($query); $num_results = $result->num_rows; echo "<p>Number of books found: ".$num_results."</p>"; for($i=0; $i<$num_results; $i++) { $row = $result->fetch_assoc(); echo "<p><strong>".($i+1).". Title: "; echo htmlspecialchars(stripslashes($row['title'])); echo "</strong><br />Author: "; echo stripslashes($row['author']); echo "<br /> ISBN: "; echo stripslashes($row['isbn']); echo "<br />Price: "; echo stripslashes($row['price']); echo "</p>"; } $result->free(); $db->close(); Line 37 is specifically: $num_results = $result->num_rows; I've been bashing my head for a couple of hours here, thank you in advance to whoever can offer any help. We have a complex, json object which is multiple levels deep. We need to search for a given property/key in the entire object (not just first occurrence, but all), and if we find the property, return where in the object each property exists, so we can modify the properties value. Figure it needs to be recursive. I am trying to run a count query and faced with the error: Notice: Trying to get property of non-object in Not sure how to resolve this error in these lines:
if($result->num_rows > 0){
while($row = $result->fetch_rows()){
Code:
<?php
$sql = "SELECT
Form_Group
COUNT(Presence LIKE '/') AS Present,
COUNT(Presence LIKE 'N') AS Absent,
FROM 'attendance'";
$result = $conn->query($sql);
?>
<?php
//Fetch Data form database
if($result->num_rows > 0){
while($row = $result->fetch_rows()){
?>
<tr>
<td><?php echo $row['Form_Group']; ?></td>
<td><?php echo $row['Present']; ?></td>
<td><?php echo $row['Absent']; ?></td>
</tr>
<?php
}
}
else
{
?>
<tr>
<th colspan="6">There's No data found!!!</th>
</tr>
<?php
}
?>
So I'm getting a "Notice: Trying to get property of non-object in" error when I'm trying to pull data from a xml. I have a complete xml that has all of the potential node that it could ever have and it loads up fine -no errors, but when I load a different xml that doesn't have all of the possible nodes it returns this error several times here is a sample of my code: $source = 'TestFile.xml'; $xml = new SimpleXMLElement($source,null,true); $result = mysql_query("SELECT * FROM tblvalues") or die(mysql_error()); //Return the table row by row while($row = mysql_fetch_array($result)) { $curblk = substr($row['fldelement'],0,3); switch ($row['fldelement']){ case "E06_04": case "E06_05": case "E06_07": case "E06_08": $cursub = $curblk."_04_0"; $xmlVal = $xml->Header->Record->$curblk->$cursub->$row['fldelement']; //grab value from xml break; ... ... ... // the cases go on for a while... ... case "E07_05": case "E07_06": case "E07_07": case "E07_08": $cursub = $curblk."_03_0"; $cursub2 = $curblk."_05_0"; $xmlVal = $xml->Header->Record->$curblk->$cursub->$cursub2->$row['fldelement']; //this is the line that the error points to break; ... ... ... And here is the sample of the xml that returns the error: Code: [Select] <E07> <E07_01>-20</E07_01> <E07_02>0</E07_02> <E07_15>-25</E07_15> <E07_16>-25</E07_16> <E07_17>-25</E07_17> <E07_18_0> <E07_18_01> <E07_18>-20</E07_18> <E07_19>-20</E07_19> <E07_20>-20</E07_20> </E07_18_01> .... .... .... The obvious problem (to me) is that my code is trying to return a value from a nonexistent xml node, for example: $xmlVal = $xml->Header->Record->$curblk->$cursub->$cursub2->$row['fldelement']; is looking for: $xmlVal = $xml->Header->Record->E07->E07_03_0->E07_05_0->E07_05 Ok, I get that, so how do I rewrite this so it's not blowing up on something so simple? Quick notes: -This same code works for a more complete xml -Rewriting the xmls is not an option as I have no control over those Edit: Almost forgot, thanks! I want to save class property values and want to write these in the database after being called from another function. Code: [Select] class model{ public $dbh; public $user_arr=array('username','password','email','location','interest','homepage'); public function insert_data() { $sql = "INSERT INTO account VALUES ('" .$user_info['username']."','".$user_info['password'] ."','".$user_info['email']."', 'user','".$user_info['location']."','".$user_info['interests'] ."','".$user_info['homepage']."')"; //if(isset($data)) echo $sql; } public function data_approoved($user){ //$user_info = new array(); $user_arr['username'] = $user['username']; $user_arr['password'] = $user['password']; $user_arr['email'] = $user['email']; $user_arr['location'] = $user['location']; $user_info['interests'] = $user['interests']; $user_info['homepage'] = $user['homepage']; Model::insert_data(); } } }//class ended The approoved_data function is supposed to set the values of $user_info array which should be later on stored in database. Please somebody help me. *Mods* PLEASE don't move this to the OOP section again. I've had no luck there, and it's not specifically an OOP question. Hi everyone, I just want to know if there's a shorthand way to create objects, as there is for arrays: Code: [Select] // shorthand array creation $foo = array( 'bar' => 0, 'baz' => array ( 'name' => 'Dave', 'gender' => 'male' ) ) Code: [Select] // is there a way to do this with objects? // not that I know so far... $foo = object( bar->0, 'baz' -> object ( name -> 'Dave', gender -> 'male' ) ) I find object-access syntax is often quicker and easier to write than array-access syntax. Have I missed something obvious that I can't just write it out this way? Cheers, Dave This topic has been moved to Application Frameworks. http://www.phpfreaks.com/forums/index.php?topic=323395.0 I get the following error when I try to pass a value to a methiod in a loop: Warning: Attempt to assign property of non-object in /Users/staceyschaller/Sites/dev_zone/ckwv2/classes/class.php on line 670 This one has me very baffled.

Thanks! hello all, I am new to php, and getting better using the object oriented approach. I have been a procedural programmer for several years, with a limited exposure to OOP. I have a question about pulling two values from an object. the following code is an excerpt from a class form. function getstocklist($currentcount){ $transactions = $currentcount['count']; $current = mysql_query("SELECT * FROM current_positions WHERE positiontype = 'long' OR positiontype = 'short'"); $tickers = ''; while ($stock = mysql_fetch_array($current)){ $tickers .= $stock['positionticker'] . ','; $stockList[] = array( 'shares' => round(($stock['positioncost']/$stock['positionprice']),0), 'date' => date("m/d/Y G:i:s", $stock['positiontime']-(45*60)), 'ticker' => $stock['positionticker'], 'type' => $stock['positiontype'], 'price' => $stock['positionprice'], ); } return($tickers); } I would like to get both the value of $tickers and the array $stockList. I am not sure how to proceed. any suggestions would be greatly appreciated. Thanks Kansas Ok. So, I'm trying to retrieve the id value from an object. Here is the code I have that works so far: Code: [Select] $object = 'object'; $koid = $this->$object; echo '<pre>'; print_r($koid); echo '</pre>'; and this is what is returns: Code: [Select] Order Object ( [id:protected] => 5 [stand_by:protected] => test [problem:protected] => test ) what do I need to do to make $koid equal the id value (5 in this case)? I am trying to get elements in a dom object to display and manipulate however i cant seem to get them all out: This is the feed: <TransactionList> <TransactionID>507821041</TransactionID> <TransactionDate>2012-03-12T13:23:00+00:00</TransactionDate> <MerchantID>547</MerchantID> <MerchantName>The High Street Web</MerchantName> <ProgrammeID>1865</ProgrammeID> <ProgrammeName>THE HIGHSTREET WEB</ProgrammeName> <TrackingReference>{CLICKID}</TrackingReference> <IPAddress>82.34.245.167 </IPAddress> <SaleValue>0.0000</SaleValue> <SaleCommission>0.0400</SaleCommission> <LeadCommission>0.0000</LeadCommission> </TransactionList> However i am trying to get more than 1 tag but i cant seem to get it right. This is my code: <?php $dom = new DomDocument; $dom -> load ( "http://xyz.com" ); $tracking = $dom -> getElementsByTagName( "TrackingReference" ); //$com = $dom -> getElementsByTagName( "SaleCommission" ); $c1 = 0; foreach( $tracking as $code ) { #echo $code -> textContent.'<br>'; $tcode = $code -> textContent; $tcom = $com -> textContent; //$com = $dom -> getElementsByTagName( "SaleCommission" ); if ($tcode !="") { $remove_it = '{CLICKID}'; $tcode = str_replace($remove_it, "", $tcode); echo $tcode.'
