[PHP] pobierz, plaintext


Chodzi o to że jesli wypelnimy plotki z The Sun to skrypt ma je wyświetlać a jeśli nie to opuszczać wiersz z plotkami The Sun.

Za pomocą funkcji isset i konstrukcji
[PHP] pobierz, plaintext 
  1. if(isset($_POST[''cos])){
  2.       // rob cos 
  3. }
[PHP] pobierz, plaintext

sprawdzaj czy dana zmienna POST istnieje.

Ale nie wiem jak to zastosować żeby CAŁY wiersz tabeli ominąć w przypadku braku wypełnienia.

Ano tak, masz sobie wiersz:

[HTML] pobierz, plaintext 
  1. <tr>
  2.     <td width="29%"><img src="http://www1.skysports.com/images/football/papertalk-logos-dailymirror.gif" /></td>
  3.     <td width="71%"><blockquote><?php echo nl2br($plotki1) ?></blockquote></td>
  4.   </tr>
[HTML] pobierz, plaintext


dodajesz więc na początku wiersza:
[PHP] pobierz, plaintext 
  1. <?php
  2. if(isset($plotki1) AND !empty($plotki1)) {
  3. ?>
[PHP] pobierz, plaintext


i na końcu:
[PHP] pobierz, plaintext 
  1. <?php
  2. }
  3. ?>
[PHP] pobierz, plaintext


No i cała filozofia.

Poza tym polecam automatyzację całego procesu poprzez generowanie tabeli automatycznie, a nie ręcznie.
