PHP - Need Help Working With Property Visibility

Hey Guys.   I have a class named CoreCartFunctions. In the class there is a protected property named $menu_item_id which is initialized  as null.   A method named GetMenuItemId assigns the $menu_item_id its value. I have tested it out using the following,  to see if a value got returned and it did

fb($menu_item_id->GetMenuItemId(), "This is the menu id");

The problem is when I access the property from a different public method in the same class it dones't return anything.

fb($menu_item_id->DisplayMenuItems());

It only returns something when I hard code a value to it.... Not sure why this is happening. Here is my full code.   Please not the example below may have some syntax errors since I just copied and paste pieces of my code, to show a quick and dirty example.

class CoreCartFunctions {


protected $menu_item_id = NULL; 


public static $items; //Equal to the a long session string

protected function GetMenuItemId() {


      foreach (self::$items as $menu_item_id_session) {


/***********************************
Get the id of the menu item item
************************************/
$this->menu_item_id = preg_match_all('/\-(.*?)\*/',$menu_item_id_session,$match_found)?$match_found[1][0]:"";
// The following line shows example of above line
// $menu_item_id = "12";

public function DisplayMenuItems(){
  

return $this->menu_item_id; // Doesn't return Item ID

}




}

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
}
?>

Hi,

I was wondering if someone can help me, I keep getting these errors.

Notice: Undefined property: stdClass::$vOptionType in /default/commonFunctions.php on line 267

That is the line from the file.

if($rsOptions[$j]->vOptionType=='colour_fromcsv' || $rsOptions[$j]->vOptionType=='size_fromcsv')

I was wondering if someone could tell me what it means and possible point me in the right direction on how to fix the issue.
Thanks,
Jordan

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.

Hi Guys

What have I done wrong?

Hey Guys. I have a shopping cart script that loops through the shopping cart session  array and assigns values to the property of a class. For some weird reason the subtotal property only works when I use the self keyword. If I use the $this-> instance variable  the sub total does not get assigned the subtoal price. Its just NULL.   Does anyone have any suggestions as to why it may not be working.   Below is a quick copy and paste of my code. Please be aware that some there may be some syntax mistakes as a result to copying and pasting part of my code that is relevant to this issue. Thanks!

class CoreCartFunctions {

protected static $subtotal;
protected $menu_item_price = NULL;

public function GetMenuItem() {

//self:items is the cart session array that is initilized in a construct method
//Assign the values for each cart array
      foreach (self::$items as $menu_item_id_session) {


$this->menu_item_price = getItems($this->menu_item_id,"menu_item_price")*$this->item_qty;

self::$subtotal += $this->menu_item_price; 
//Does not work with the following ---> $this->subtotal += $this->menu_item_price; 

}




}

For example:

class People{
    var $them = array();
    
    function groupPeople(){
      foreach($this->them as $him){
           echo $him.", ";
      }
   }
}

$people  = new People;
$people->them = array('Harry','Todd');

$people->them = array('Tom','Jerry');
$people->groupPeople(); // result: Tom, Jerry,


I think this code is working. However, I need to merge those array above, array('Harry','Todd') and array('Tom','Jerry') So I can get array('Harry','Todd','Tom','Jerry') and a list of names as a result. Maybe I should use array_merge, but how? A little help would be appreciated.

Thank you in advanced,

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...?

I am using the following code   foreach ($fbdata->data as $post )
{
$posts .= '<li>';
$posts .= '<p>' . $post->message . '</p>';
$posts .= date('d-M-y', strtotime($post->created_time));
$posts .= '</li>';
}   and if the message propeerty doesn't exist I get the message above.   Any ideas on the best way to fix this?

I want to save class property values and want to write these in the database after being called from another function.
Code: [Select]

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.
