<?php
//some embeded php (here is the addEdit component)
.
.
echo '
<td id="row_'.$row['id'].'" style="display: none;">
 <input type="text" name="addEdit" id="addEdit_row_'.$row['id'].'" value="" size="4"/></td>
<td>
        <input type="submit" name="add" value="A"  onClick="addObs('.$row['id'].'); return false;"/>
';
</td>
.
.//end oh php code
?>
<!-- end of html code -->

PHP code:

if(isset($_POST['add']))
{
 //echo 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa';
 if (isset($_POST['addEdit']))
 {
  echo 'post: '.$_POST['addEdit'];
 }
}

Did you close <form> tag ?

Try to:

var_dump($_POST);

Try

<form name='frm' method='POST' action='<?php echo $_SERVER['PHP_SELF']?>'>
