PHP - Assigning An Object Of Multiple Instances To Another Object's Property

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.

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...?

Hi Guys

What have I done wrong?

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.

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

I have an object which is very expensive to create, and is fairly large but by no means enormous.  The object has two tasks:

Display to the user what can be changed in a database. Make some or all of those changes based on user input.

Instead of creating it first to perform the first task, I would like to serialize it and store it somewhere and then restore it to perform the second task to reduce user wait time.  Communication of both tasks is as follows where the web client first makes a XMLHttpRequest and then cURL is used for the remaining:

Web Client -> Web Server -> REST API Server -> Time Historian Application (and then back in the same order)

In addition, both of these tasks take significantly longer than 30 seconds resulting in cURL error 28.  I certainly can investigate to determine which of the requests are causing this error, however, feel that the solution to persisting the object might solve this issue as well.

I am thinking of making the REST API server responsible for temporarily storing the object, and am considering the following:

Web client makes XMLHttpRequest to web server and passes session cookie. Web server makes cURL request to REST API server and passes that same cookie (maybe a bad idea?). REST API server initiates the time historian application, spawns some new process, and replies to the web server maybe with some expected wait time duration, and web server in turn responds to web client. Spanned process when object is complete serializes the object's content and saves it as JSON using the session cookie as the filename. Web client periodically makes requests to web server which in turn make requests to REST API server and when the JSON file is available, recreates the object, executes the applicable method, and replies with the applicable content. Web client sends user data to the web server and in turn to the REST server to initiate the second task. Web client similarly periodically makes requests to web server which in turn make requests to REST API server to check if complete and if so the JSON object file is deleted. If request has not been fulfilled within 24 hours or so, JSON object file is deleted.

I would appreciate any general feedback or recommendations how best to accomplish this, and whether using some 3rd party framework such as Gearman, ReactPHP, redis, etc might simplify matters.

Thank you

I have a loop creating a block_vars array for displaying records from a database. (In this case auction listings).
The following code creates this array:

// get random selection of 6 items for home page display
$query = "SELECT id, title, current_bid, pict_url, ends, num_bids, minimum_bid, bn_only, buy_now, subtitle, starts, ends, reserve_price
        FROM " . $DBPrefix . "auctions
        WHERE closed = 0 AND suspended = 0 AND starts <= " . $NOW . "
        ORDER BY RAND() DESC LIMIT 6";
$res = mysql_query($query);
$system->check_mysql($res, $query, __LINE__, __FILE__);
   $showendtime = false;
   $has_ended = false;
      
$k = 0;
while($row = mysql_fetch_assoc($res))
{
   $ends = $row['ends'];
   $difference = $ends - time();
   if ($difference > 0)
   {
      $ends_string = FormatTimeLeft($difference);
   }
   else
   {
      $ends_string = $MSG['911'];
   }
   
   $high_bid = ($row['num_bids'] == 0) ? $row['minimum_bid'] : $row['current_bid'];
   $high_bid = ($row['bn_only'] == 'y') ? $row['buy_now'] : $high_bid;
   
   //determine whether the auction has a Buy Now price, show if appropriate.
   if($row['buy_now'] == '0.0000') {
   $bnamount = "";
   } else {
   $bnamount = "<a href='" . $system->SETTINGS['siteurl'] . "buy_now.php?id=" . $row['id'] ."'>$" . substr($row['buy_now'], 0, -2) . "<br />" . "Buy Now</a>";
   }
      
   //determine if the auction has a reserve set and if it has been met. display appropriate symbol
   if($row['reserve_price'] == '0.0000' && $row['bn_only'] == 'n' && ($row['current_bid'] < $row['minimum_bid'])) {
      $flag = '<img src="images/noreserve.gif" alt="No Reserve">';
      $flagdesc = " No Reserve!";
      $bnonly = "Current Bid<br />";
      } else {
         if($row['current_bid'] >= $row['reserve_price']) {
         $flag = '<img src="images/reservemet.gif" alt="Reserve Met">';
         $flagdesc = " Reserve Met!";
         $bnonly = "Current Bid<br />";
         } else {
         $flag = '<img src="images/noflag.gif">';
         $flagdesc = "";
         $bnonly = "Current Bid<br />";
         }
      }
   if($row['reserve_price'] == '0.0000' && $row['bn_only'] == 'y') {
      $flag = '<img src="images/noflag.gif">';
      $flagdesc = "";
      $bnonly = "Asking Price ";
      $bnamount = "";   
      }

   $template->assign_block_vars('randomitems', array(
         'ID' => $row['id'],
         'BID' => $bnonly . "$" . substr($high_bid, 0, -2),
         'IMAGE' => (!empty($row['pict_url'])) ? 'getthumb.php?w=' . $system->SETTINGS['thumb_show'] . '&fromfile=' . $uploaded_path . $row['id'] . '/' . $row['pict_url'] : 'images/email_alerts/default_item_img.jpg',
         'TITLE' => $row['title'],
         'BUY_NOW' => $bnamount,
         'SUBTITLE' => $row['subtitle'],
         'TIMELEFT' => $ends_string,
         'NUMBIDS' => $row['num_bids'],
         'FLAG' => $flag,
         'FLAGDESC' => $flagdesc
         ));
   $k++;
   
}

Pretty straightforward. You will see I have a TIMELEFT value which will show on my home page as no.days, no.hours, no.mins until it closes etc.
Here is the html in the tpl file:
Code: [Select]
<!-- BEGIN randomitems -->
            <div style="float:left;display:block;width:99%;border-bottom:#CCCCCC 1px solid;padding:2px;">
                <div style="display:block;">
                 <table width="100%">
                  <tr>
          <td align="center" style="vertical-align:middle;width:120px" >
       <a href="{SITEURL}item.php?id={randomitems.ID}"><img src="{randomitems.IMAGE}" alt="{randomitems.TITLE}" style="border: none;width:120px"></a>
       </td>
       <td align="left" width="40%">
        <table style="width:100%; vertical-align:middle; margin:0 auto">
         <tr>
          <td><a id="itemdesc" href="{SITEURL}item.php?id={randomitems.ID}">{randomitems.TITLE}</a><br />
                      {randomitems.SUBTITLE}</td>
                     </tr>
                     <tr>
                      <td id="closes">Closes in:{randomitems.TIMELEFT}</td>
                     </tr>
                     <tr>
                      <td>{randomitems.FLAG}{randomitems.FLAGDESC}</td>
                     </tr>
                    </table>
       </td>
       <td id="buynow" align="center" width="15%">
       {randomitems.BUY_NOW}
       </td>
       <td id="currentbid" align="center" width="25%">
       {randomitems.BID}
       </td>
      </tr>
     </table>
                </div>
            </div>
<!-- END randomitems -->

This works quite nicely for me.
 
What I want, and cannot manage thus far is to have the TIMELEFT value count down.
 
The closest I have come is using a function like this:
Code: [Select]

<script type="text/javascript">
$(document).ready(function() {
 var currenttime = '{randomitems.TIMELEFT}';
 function padlength(what)
 {
  var output=(what.toString().length == 1)? '0' + what : what;
  return output;
 }
 function displaytime()
 {
  currenttime -= 1;
  if (currenttime > 0){
   var hours = Math.floor(currenttime / 3600);
   var mins = Math.floor((currenttime - (hours * 3600)) / 60);
   var secs = Math.floor(currenttime - (hours * 3600) - (mins * 60));
   var timestring = padlength(hours) + ':' + padlength(mins) + ':' + padlength(secs);
   $("#ending_counter").html(timestring);
   setTimeout(displaytime, 1000);
  } else {
   $("#ending_counter").html('<span class="errfont">{L_911}</span>');
  }
 }
 setTimeout(displaytime, 1000);
});
</script>

This code is placed in the tpl file and I simply give an html element the appropriate ID. The problem with this is that it would only show a countdown timer for the first item returned, which is no good as there are always six items returned.
 
Can anyone offer a suggestion on how I could go about this? I can PM anyone with suggestions with a link to my development site so you know what I am raving about.

I am using mod_php with Apache/2.4.6 (CentOS).  I currently do not have multiple versions of PHP running on my server, but wish to do so now.

Will I need to use php-fpm?  Even if multiple instances can be accomplished with mod_php, is it typically preferred to use php-fpm?

Any unusual gotcha's that I should be aware of?

Will I need to uninstall mod_php before installing php-fpm?

I previously used remi-php73 repo.  Better to install from source?

Thanks

I made a small script and it says that my database object isn't an object.

I connect to my pdo database via:

<?php

try {
$db = new PDO("mysql:host=localhost;dbname=database", "root", "root"); 
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
}  
catch(PDOException $e) {  

echo $e->getMessage();
  
}

?>

 

The error I get is

Code: [Select]
Notice: Undefined variable: db in /Users/JPFoster/Sites/jobiji_sandbox/extensions/tasks.php on line 21

Fatal error: Call to a member function query() on a non-object in /Users/JPFoster/Sites/jobiji_sandbox/extensions/tasks.php on line 21


here's where the error is
$grabber = $db->query('SELECT * WHERE user_id =' . $userid);
$grabber->setFetchMode(PDO::FETCH_OBJ);

while ( $row = $grabber->fetch() ){

$display = '<div>Task Name: ' . $row->name .'</div>';
$display .= '<div>Task Details: <p>'. $row->details  .'</p></div>';
//$display .= '<div>'. $this->checkifDone($row->task_status) .'</div>';
$display .= '<div>Task Due: '. $row->task_due . '</div>';
echo $display;
}


could anyone tell me where this issue is originating I followed a fairly simple tutorial that didn't seem to work.


Thanks!

Hi folks,

I was wondering how to do this. I want the if statement to detect if the query string has any of these values. so im trying to assign them all to the same variable. However, this code wont work. Whats the trick here?

<?php
$primary=$_GET['intro'];
$primary=$_GET['port'];
$primary=$_GET['about'];
$primary=$_GET['contact']; 

         if(isset($primary)){
     echo "<img src='graphics/left-a.png'>";}
else {echo "<img src='graphics/leftb.png'>";}?>

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
