PHP - Trying To Get Property Of Non-object, Simplexml Question.

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
}
?>

 

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.

Hi Guys

What have I done wrong?

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.

Hello, I am sorry for this question in advance. I will try to explain it as detailed but, as short as possible so bare with me. I have a script that I did that parses an XML file and outputs the info in a table. The tables are created with each entry in XML file. Everything works great and as designed except for when there is no data. I know why it is doing this, I am just not sure how to approach fixing this. So here is what the data looks like where there is nothing and what the table shows. I am posting a screenshot of the XML file as I am not sure it will be empty if I post the link.   

*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

I am trying to sort these fields alphabetically by $name - $documents

have run past multiple sort methods but none seem to work. I was hoping someone here knew an easy method to do this


xml data:
<database>
<name>Test</name>
<documents>0</documents>
<sections>0</sections>
</database>
<database>
<name>Test2</name>
<documents>100</documents>
<sections>0</sections>
</database>


current code:
<?php
$request_url = "http://10.100.100.100:9000/a=getstatus";
$xml = simplexml_load_file($request_url) or die("feed not loading");
echo "<table width=\"300\" border=\"0\" cellspacing=\"0\" cellpadding=\"2\">\n"; 
echo "  <tr>\n"; 
echo "    <td>Thor Databases</td>\n"; 
echo "    <td>Count\n";
echo $xml->responsedata->databases->num_databases;
echo "    </td>\n"; 
echo "  </tr>\n"; 
foreach ($xml->responsedata->databases->database as $db) {
          echo"<tr><td>",$db->name,"</td><td>",$db->documents,"</td></tr>\n";
  }
echo "</table>\n";
?>


Thanks,

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?

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. It will work the first time, and seems to work every other time, so I have no clue what is wrong. Here is the code:

This code is part of my "display" class:

function display_partner ($type,$loc,$rand=0,$narrow=0) {
$this->partners = new partner($this->cxn);
$display = '
<div id="cont_info" class="partner-list">
<div>
<h3 class="settings">'.ucfirst($loc).' '.ucfirst($type).last_letter($type).'s</h3>
</div>
<div class="settings-value" style="height:12px;padding:0;margin:0;text-align:right;padding-right:10px;">
<a href="" class="trunc">Add your organization to this list</a></p>
</div>
<div style="height:2px;padding:0;margin:0;">
<hr class="account" />
</div>
';
$ids = $this->partners->get_partners_list($type,$loc,$rand);
for ($b=0;$b<sizeof($ids->id);$b++) {
$this->partnerID = $ids->id[$b];
$display .= ($narrow)? $this->card_partner_narr():$this->card_partner();
if ($b!=(sizeof($ids->id)-1)) { $display .= '<hr class="account" />'; }
}

if (sizeof($ids->id)==0) {
$display .= '<div style="color:#999999;display:line;text-align:center;height:20px;">No Partners found for '.ucfirst($loc).' '.ucfirst($type).'</div>';
}

$display .= '
</div>';

return $display;

}

function card_partner () {
$this->partners->set_partner_id($this->partnerID);
$part_info = $this->partners->get_partner_info();
if ($part_info) {
$display .= '
<table class="settings">
<tr>
'.$this->show_if($part_info['partLogo']['val'],'<td class="settings-value" rowspan="2"><img src="'.LOGO_FOLDER.$part_info['partLogo']['val'].'" '.resize_img(LOGO_FOLDER.$part_info['partLogo']['val'],175).'alt="'.$part_info['partName']['val'].'" /></td>').'
<td class="settings-value" colspan="2"><h5>'.$part_info['partName']['val'].'</h5></td>
</tr>
<tr>
<td class="settings-value">
<span style="color:999999;">'.$part_info['partAddress']['val'].'<br />

<a href="'.$this->form->show_href($part_info['partWeb']['val']).'" target="_blank">'.$part_info['partWeb']['val'].'</a>
</td>
<td class="settings-value">'.$part_info['partInfo']['val'].'</td>
</tr>
</table>
';
}

return $display;
}



This code is part of my "partners" class:

function set_partner_id($partID) {
echo '<p>partID: '.$partID.' '.gettype($partID).'<br>
$this->partner->id: '.$this->partner->id.'</p>';
$this->partner->id = $partID; ///*** ERROR HAPPENS HERE ***/
echo '<p>id set: '.$this->partner->id.'<br>
$this->partner->id: '.$this->partner->id.'</p><hr>';
}

function get_partner_id() {
return $this->partner->id;
}

// gets user info at login
function get_partner_info() {
$this->partner = $this->cxn->proc_info('partner','partID',$this->partner->id);//$this->partner->id
return $this->partner;
}


The following is the output generated:

partID: 24 string
$this->partner->id:
id set: 24
$this->partner->id: 24

partID: 26 string
$this->partner->id:
Warning: Attempt to assign property of non-object in /Users/staceyschaller/Sites/dev_zone/ckwv2/classes/class.php on line 670
id set:
$this->partner->id:

partID: 17 string
$this->partner->id:
id set: 17
$this->partner->id: 17


partID: 25 string
$this->partner->id:
Warning: Attempt to assign property of non-object in /Users/staceyschaller/Sites/dev_zone/ckwv2/classes/class.php on line 670
id set:
$this->partner->id:

As you can see, the value passes to $this->set_partner_id($partID) each time. It is formatted as a string. When it assigns the value to $this->partner->id, however, sometimes it works, and sometimes it doesn't. It's probably something obvious, but I've racked my brain to see what it is. Any ideas?

I have instantiated a object and the constructor has an other object added the issue arises when I  extent the first object how do I access the object in the variable. below is a stripped down example. I want accessfoo to access class a method foo that is stored in a var in class b is this possible.
Code: [Select]
class a {
 private function foo(){
 return "hello word";
}
}


$a = new a()


class b {
    private $obj;
    public function __construct ($obj){

        $this->obj= $obj;

    }

}

class c extends b{

private function accessfoo(){
    $this->obj ?????????????
}

$c = new class($a)

I can call the following function successfully as a single php program

  // Acknowledge and clear the orders
   function ack($client, $merchant, $id) {
         $docs = array('string' => $id);
         $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs);
         $result = $client->call('postDocumentDownloadAck', $params);
         return $result;
         }
with

   $result = ack($t, $merchant,'2779540483');

successful output

    [documentDownloadAckProcessingStatus] => _SUCCESSFUL_
    [documentID] => 2779540483

I'm trying to figure out how to call this function as an object from another program.

Trying the following gives error  ***Call to a member function call() on a non-object***

  function postDocumentDownloadAck($t, $merchant, $id) {
     $this->error = null;
     $docs = array('string' => $this->id);
     $params = array('merchant' => $this->merchant, 'documentIdentifierArray' => $docs);

 **  I've tried the following which does nothing
     $result = $this->soap->call('postDocumentDownloadAck', $params);

** I've tried the following   -  which gives error "Call to a member function call() on a non-object"
     $result = $this->t->soap->call('postDocumentDownloadAck', $params);

     if($this->soap->fault) {
        $this->error = $result;
        return false;
     }

     return $result;
  }


***

calling program snippet for above function
   $merchant= array( "merchant"=> $merchantid, "merchantName" => $merchantname, "email"=> $login, "password"=> $password);
   $t = new AmazonMerchantAPI($merchantid, $merchantname, $login, $password);
   $documentlist= $t->GetAllPendingDocumentInfo('_GET_ORDERS_DATA_');
   $docid = $documentlist['MerchantDocumentInfo'][$i]['documentID'];
   $docs = array('string' => $docid);
   $ackorders = $t->postDocumentDownloadAck($t, $merchant,$docs);

Any ideas of what I'm doing wrong are greatly appreciated.

Ok so I have a url that is an XML doc, it says at the top

"This XML file does not appear to have any style information associated with it. The document tree is shown below."

and it has info like this

Code: [Select]

<outer>
  <xml>
    <viewer>
      <user>
        <id>1245789</id>
        <name>CLueless</user>
        <business>none</business>
      </user>
    </viewer>
  </xml>
</outer>


How would I load the link and then assign everything to a variable like id, name and business

I usually use something like this but Im trying to get learn simple xml



$info = file_get_contents('url');
$id = explode('<id>', $info);
$id = explode('</', $id[1]);
$name = explode('<name>', $info);
$name = explode('</', $name[1]);
$biz = explode('<business>', $info);
$biz = explode('</', $biz);
