        0   => array( 'Edit News','enabled',$page['script'],''),    
    );
    $selectValue = $_POST['news'];
    if(isset($_POST['saveId']))
    {
     if(($selectValue)==4){

      $sql=" SELECT DISTINCT ad_news_texte.headline, ad_news.datum_archiv

Always try to format your code properly so the reader can understand which statement/clause ends where, i found a few issues in your code which might be the reason of the issue you are having

  • Your if(isset($_POST['saveId'])) statement body ends right after the while statement body, while there is still some code remaining which should logically be executed within the body of the if statement

  • You are not concatenating the previously set data of $html to the newly set $html data, so only the last bit will stay in the variable

Here is the altered code, i didn't test it but i fixed the two issues i found and applied some formatting so other can understand it better

if($param['aktion'] == 'save-widget-news')
{
    //$param['news'] 
    //UPDATE SQL...

    $page['register-news'] = array(
        1   => array( 'News','aktiv',$page['script'],'',''),
        0   => array( 'Edit News','enabled',$page['script'],''),    
    );
    $selectValue = $_POST['news'];
         if(($selectValue)==4)
         {

            $sql=" SELECT DISTINCT ad_news_texte.headline, ad_news.datum_archiv
            FROM ad_news_texte
            INNER JOIN ad_news_oe ON ad_news_texte.news_id = ad_news_oe.id_ad_news
            INNER JOIN ad_news ON ad_news_oe.id_ad_news = ad_news.id
            WHERE ad_news.datum_archiv
            BETWEEN curdate( ) - INTERVAL DAYOFWEEK( curdate( ) ) +28

You are affecting the same variable multiple times :

while($row = mysql_fetch_assoc($sql_select)) {
    $news= $row['headline'] . " " .$row['datum_archiv'] ;
}

Put your html code in while loop : 

$html = null;

while($row = mysql_fetch_assoc($sql_select))
{
    $news = $row['headline'] . " " .$row['datum_archiv'] ;
    $html .= '<table width="538" cellspacing="0" cellpadding="0" border="0">...</table>';
}

EDIT :

You cannot insert your while like you have done. Concatenation is for string not for a loop. Also echo isn't needed when you use concatenation.

$html = '<table width="538" cellspacing="0" cellpadding="0" border="0">
           <tr>
             <td>
               ...';


while($row = mysql_fetch_assoc($sql_select))
{ 
    $news = $row['headline'] . " " .$row['datum_archiv'];

    $html .= '<p class="welcome-subheadline"><input type="text" name="type" value="'. $news .'" ></p>';
}                                                                                   

$html .= '</table>......';
