hidden html form in php with javascript

i'm trying to pass parameter with a html form in php, i have a php page that fill a html table:

$html = '';
$html .= '<form id="form1" action="search.php" method="post">';
$html .= '<tr>';
$html .= '<td>id</td>';
$html .= '<td><a href="javascript:;"onclick="document.getElementById(\'form1\').submit();">name</a></td>';
$html .= '<td>surname</td>';
$html .= '<td>language_id</td>';
$html .= '<td><span class="label label-success">Status_code</span></td>';
$html .= '</tr>';
$html .= '<input type="hidden" name="mess" value=\'Hello\'>';
$html .= '</form>';

i can see in my html the table, when i click on the href, the search.php page it's open, but i can't see the 'Hello' value, this is the search.php:

<?php

$name0 = $_POST['mess'];
echo $name0;

?>

what is wrong?

The problem is with your browser not php. a good browser wont show this error. try this

<?php
$html = '';
$html = '<table>';
$html .= '<form id="form1" action="search.php" method="post">';
$html .= '<tr>';
$html .= '<td>id</td>';
$html .= '<td><a href="javascript:;"onclick="document.getElementById(\'form1\').submit();">name</a></td>';
$html .= '<td>surname</td>';
$html .= '<td>language_id</td>';
$html .= '<td><span class="label label-success">Status_code</span></td>';
$html .= '</tr>';
$html .= '<input type="hidden" name="mess" value=\'Hello\'>';
$html .= '</form>';
$html .= '</table>';
echo $html;
?>

and search.php

<?php

$name0 = $_POST['mess'];
echo $name0;

?>

I tried this, honestly I don't know why you have SO many .= so, I got rid all of them

<?php $html = '
<form id="form1" action="search.php" method="post">
<tr>
<td>id</td>
<td><a href="javascript:;"onclick="document.getElementById(\'form1\').submit();">name</a></td>
<td>surname</td>
<td>language_id</td>
<td><span class="label label-success">Status_code</span></td>
</tr>
<input type="submit" name="mess" value="Hello">
</form> ';

echo $html;

in your form 

<?php
$html = '';
$html .= '<form id="form1" action="search.php" method="post">';
$html .= '<tr>';
$html .= '<td>id</td>';
$html .= '<td><a href="javascript:;"onclick="document.getElementById(\'form1\').submit();">name</a></td>';
$html .= '<td>surname</td>';
$html .= '<td>language_id</td>';
$html .= '<td><span class="label label-success">Status_code</span></td>';
$html .= '</tr>';
$html .= '<input type="hidden" name="mess" value=\'Hello\'>';
$html .= '</form>';
echo $html;
?>

in search.php

<?php echo $_REQUEST['mess'];?>

As you said on click of href you are opening search.php and trying to get post values is not possible.

either pass value by appending the url like search.php?mess=YourValue

or submit the form so that you can read with $_POST
