why is this ajax call not reading my internal php?

Question

Hi folks,

Too many edits to keep track of, but I have simplified the issue. I have this code in my index.php:

<div class="calendar_top">
<?php
include(SITE_ROOT . "/includes/sub_top_divs.php"); ?>
</div>
<table class="tablebodycontainer"><tr><td>

<?php

    include(SITE_ROOT . "/includes/view-monthly-calendar-ajax.php");

?>
</td></tr></table>

<?php include(SITE_ROOT . "/includes/copyright.php"); ?>
</div>

The subtop above contains the navigation links:

includes/subtop-divs.php:

<?php
    //include(SITE_ROOT . "/includes/set-variables.php");//dateFormat($date)
    echo "<table class='navtabs' cellpadding='0' cellspacing='0'>";
    echo "<tr><td class='right'>";
    echo buildMenuNavigation($currentPageIndex);
    echo '</td></tr></table>';
?>

Here is that buildMenuNavigation function:

function buildMenuNavigation($currentIndex=0) {

  $navtabs = array(
  '0'=>array('Monthly'=>'index.php'),
  '1'=>array('Daily'=>'agenda.php'),
  '2'=>array('Admin'=>'admin/view-timelines.php'),
  '3'=>array('Help'=>'help.php'),
  );

  $sep = '<li>&nbsp;|&nbsp;</li>';$builtNav=array();
  foreach($navtabs as $index=>$tablinks) {  
    foreach($tablinks as $key=>$value)  {
      $class='';
      if($index==$currentIndex) {
        $class=' class="selected"';
      }
      //pr($value);
      $builtNav[] = '<li><a href="' . SITE_URL . '/' . $value.'"' . $class .'>&nbsp;'.$key.'&nbsp;</a></li>';
    }
  }
    return '<ul>' . implode($sep,$builtNav) . '</ul>';
}

The only data that actually changes when switching pages is the contents in the above:

<?php

    include(SITE_ROOT . "/includes/view-monthly-calendar-ajax.php");

?>

So this seems like a perfect candidate for ajax.

Here is the contents of /includes/view-monthly-calendar-ajax.php:

<?php
$counter = 0; 
?>
<table class="tabbody">
  <tr>
    <td class='head unselectable'>Sun</td>
    <td class='head unselectable'>Mon</td>
    <td class='head unselectable'>Tue</td>
    <td class='head unselectable'>Wed</td>
    <td class='head unselectable'>Thu</td>
    <td class='head unselectable'>Fri</td>
    <td class='head unselectable'>Sat</td>
  </tr>
  <tr>
    <?php

      $daysInrow++;
      $zero = "";
      if($i < 10)
      {
        $zero = "0";
      }

      $t_date  = $year."-".$month."-".$zero.$i;

        // Workout when the first day of the month is
        $firstDay = date("w", $timeStamp);

        for($j = 0; $j < $firstDay; $j++, $counter++)
        echo "<td class='tddaybox'></td>";
      }

      if($counter % 7 == 0)
      {
        $daysInrow = 1;
        echo "</tr><tr>";
      }

      if(date("w", $timeStamp) == 0)
        if($i == date("d") && $month == date("m") && $year == date("Y"))
              $class = "class='today'";
          else
            $class = "class='weekend'";
      else
      if($i == date("d") && $month == date("m") && $year == date("Y"))
      $class = "class='today'";
      else
      $class = "class='normal'";

     $numric_time =  getNumericTime($_SESSION['userData']['timezone']);//Get the numeric timezone

      $query            =   "SELECT *  FROM events  WHERE date(convert_tz(StartDate,'+00:00','". $numric_time."'))='".$t_date."' AND UserID='" . $_SESSION['userData']['UserID'] ."' ORDER BY PTLType ASC";
        //br();
      $result           =   mysql_query($query);

<input type="hidden" id='lastselectedday' value='' />

So the output for all of the above is correct now, but when I try and do this:

<form>
<input type="button" value="Display Message" onclick="getData('/Dev2/includes/view-monthly-calendar-ajax.php', 'targetDiv')">
</form>
<table class="tablebodycontainer">
<tr>
<td id="MainCalendarContainer">
<div class="ajaxswap" id="targetDiv">

</div>

The output of the ajax call doesn't execute the php.

Answer 1

The PHP code is processed by the server; the browser will never see it unless the web server glitches.

Answer 2

PHP is preprocessed before the data is sent to the client. The server parses and executes the php code and only sends what is output by the code. If you want to get the full file you would need to have it not processed by php, for instance by renaming the file extension to something else.

Answer 3

First off, you shouldn't pull <script> elements via Ajax, they are not going to be interpreted and if they are, they are going to break everything on the second request.

Do some debugging by calling /Dev2/includes/view-monthly-calendar-ajax.php in your browser first. Check out the source code of what you are getting. PHP runs before the document is delivered, so there is no way to pull the HTML, but not the contents generated by PHP. They are one entity.

You either have an error in your PHP code that leads to the wrong output, or your PHP code is not being interpreted at all, which is easy to spot because the original PHP source code will be in the document's source code (which must never, ever happen).

Answer 4

You should implement another php page such as...

 getData('getPHP.php?page=/Dev2/includes/view-monthly-calendar-ajax.php', 'targetdic');

Then in that page you need to implement a method to load the php file as a string and return it. at the moment the php is being interpreted as you would expect.
