Hello there,
I have a problem with a form, as soon as I fill the for using a query. The buttons doesn't work anymore. They work when i open the page, they have somoe js to emable and diable controls. but when i do a search and get the form filled, non of the controls work anymore. Any advise?

Hi everyone.
I am David and I am new to web design and php. I am following a Lynda.com tutorial on php and sql.
I have reached a certain point in the tutorial where I am reading values back from my database in to a php variable. The variable is holding an array data type and I am accessing the element within the array.

I want a HTML select control and 2 radios buttons to reflect the values in the database.
Therefore the Select control should read a numeric value of type int and the radio buttons are reflecting either a 1 or a 0.

Firstly the code for the Select control uses a for loop to count the array elements and load the count into the Select control. The example uses php mixed with html. The for loop will count the number of element and add a number to the select control. The an If statment is used to make a decision if the count variable equals the value in the array element $sel_subject['position'] then select that value. This does not happen, and I can not seem to get it to work.

                                           <p>Position:
                  <select name="position">
                     <!--use a php block so as to use some php variables -->
                     <!--Use these variables with the get_all_sublects function. -->
                     <!-- This function will return all the dataset -->
                     <?php
                        $sel_subject = get_all_subjects();
                        //Then use the mysql fuction to retuen the numberic value of all the rows.
                        $subject_count = mysql_num_rows($sel_subject);
                        //$subject_count + 1 becauce we are adding a subject
                        for($count=1; $count <= $subject_count+1; $count++)
                        {
                           echo "<option value=\"{$count}\"";

                           if ($sel_subject['position'] == $count)
                           {
                              echo " selected";
                           }
                           
                           echo ">{$count}</option>";
                        }
                     ?>
                  </select>
               </p>

Secondly the radio buttons do something similar in that i want them to reflect the value in the array element. If a 1 then True and so be checked or 0 and so false and so be unchecked.

                                             <p>Visible:

                  <input type= "radio" name= "visible" value= "0"
                  <?php if ($sel_subject['visible'] == 0)
                  {
                     echo 'checked=" checked"';
                  }
                  ?>
                  >No</input>
               &nbsp;
                  <input type= "radio" name= "visible" value= "1"
                  <?php if ($sel_subject['visible'] == 1)
                  {
                     echo 'checked=" checked"';
                  }
                  ?>
                  >Yes</input>
               </p>

Again this doesn't work either. So in summary, I cant get the php code to affect the html form controls and relay the stored data to the user.
I have been racking my brain for days and getting no where. Please can anyone help me with this.

I would be very grateful.
All the best Irish_Dave

I have php code that uses mp3 audio files stored in a database for the user to listen to. The page loads and the audio controls work and the files play on a desktop and laptop just fine. When trying to play a file on an android or IPhone, when you press the play (or any other control) nothing happens. It acts like the page is static. There is a home button on the webpage and it works so I know the page is interactive. Below is the code. I would appreciate any help. Thank you.

<?php
  $sermons = $database->select("sermon","*");;
  foreach( $sermons as $sermon )
  {
    $audio_file = 'http://xxxxxxx.com/sermons/'.$sermon['file_name'];
    $player = "<audio id='sermon_'$sermon[id] controls>
                <source src='$audio_file' type='audio/mpeg'>
                <source src='$audio_file' type='audio/mp3'>
                Your browser does not support the audio element.
              </audio>";
    echo "<tr>
          <td>$sermon[sermon_date]</td>
          <td>$sermon[title]</td>
          <td>$sermon[speaker]</td>
          <td>$player</td>
          </tr>";
  }
  ?>

I have mysqli object in Database class base:

[color=]database class:[/color]

class Database {
  private $dbLink = null;
  
  public function __construct() {
    if (is_null($this->dbLink)) {
      // load db information  to connect
      $init_array = parse_ini_file("../init.ini.inc", true);
      $this->dbLink = new mysqli($init_array['database']['host'],
                           $init_array['database']['usr'],
                           $init_array['database']['pwd'],
                           $init_array['database']['db']);
  
      if (mysqli_connect_errno()) {
        $this->dbLink = null;
      }
    }
  }

  public function __destruct() {
    $this->dbLink->close();
  }
}


Class derived is Articles where I use object dBLink in base (or parent) class and I can't access to mysqli methods (dbLink member of base class):

Articles class:

require_once ('./includes/db.inc');

class Articles extends Database{
  private $id,
              ....
              ....
             $visible = null;
  
  public function __construct() {
    // Set date as 2009-07-08 07:35:00
    $this->lastUpdDate = date('Y-m-d H:i:s');
    $this->creationDate = date('Y-m-d H:i:s');
  }
  
  // Setter
  ....
  ....

  // Getter
  ....
  ....

  public function getArticlesByPosition($numArticles) {
    if ($result = $this->dbLink->query('SELECT * FROM articles ORDER BY position LIMIT '.$numArticles)) {
      $i = 0;
      while ($ret = $result->fetch_array(MYSQLI_ASSOC)) {
        $arts[$i] = $ret;
      }
      $result->close();
      return $arts;
    }
  }
}


In my front page php I use article class:


include_once('./includes/articles.inc');
$articlesObj = new articles();
$articles = $articlesObj->getArticlesByPosition(1);
var_dump($articles);


[color=]Error that go out is follow[/color]

Notice: Undefined property: Articles::$dbLink in articles.inc  on line 89

Fatal error: Call to a member function query() on a non-object in articles.inc on line 89

If I remove constructor on derived class Articles result don't change 
Please help me
