title: Put DIV ID into a PHP Variable
body: <p>I am wanted to get the id's of all the divs on my page with the class <code>archive</code> and put them in a MySQL query to check and see if the ids are archived in the database.</p>
  
  <p>So basically I am wondering how I can do this: <code>$div = $(this).attr('id');</code></p>
  
  <p>Then I would throw it into the loop to check:</p>
  
  <pre><code>$matches = mysql_query("SELECT * FROM content WHERE `div` = '$div'");
          while ($post = mysql_fetch_assoc($matches)) 
          {
              if (mysql_num_rows($matches) &gt; 0)
              { 
                //DO THIS
              }
          }
  </code></pre>
  
  <p>UPDATE</p>
  
  <p>I have this code for the AJAX now:</p>
  
  <pre><code>$('div.heriyah').each(function() { 
  var curID = $(this).attr('id'); 
  $.post("admin/btnCheck.php", { div : curID }, function(data) {
  if (data == "yes") {
      $('#' + curID).html('&lt;div class=\"add\"&gt;&lt;div id=\"add_button_container\"&gt;&lt;div id=\"add_button\" class=\"edit_links\"&gt;  + Add Element&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div class=\"clear\"&gt;&lt;/div&gt;&lt;/div&gt;');
  } else {
      $('#' + curID).html('&lt;div class=\"add\"&gt;&lt;div id=\"add_button_container\"&gt;&lt;div id=\"add_button\" class=\"edit_links\"&gt;  + Set As Editable Region&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div class=\"clear\"&gt;&lt;/div&gt;&lt;/div&gt;');
  }
    });
  });
  </code></pre>
  
  <p>And my PHP:</p>
  
  <pre><code>$matches = mysql_query("SELECT * FROM content WHERE `div` = '".$_POST['div']."'");
   if (mysql_num_rows($matches) &gt; 0)
   { 
      echo "yes";
   } else {
      echo "no";
   }
  </code></pre>
  
  <p>What am I doing wrong?</p>
