PHP filtrovanie formulara

jorg22

Cafte pomozte mi pls neviem ako urobit aby ked je vo formulari napisane "Vas nazor..." aby ho neodosielal.Dufam ze chapete.
Tu je ten formular:

Kód: Vybrať všetko

<form method="get" action="posli.php">
  <div align="left" class="style27">
    <p><span class="style28"><span class="style31">Nick:</span></span></p>
    <p><span class="style28"><span class="style29">            <input name="nick" type="text" value="Nick...." maxlength="10" onFocus="if(this.value=='Nick....')this.value='';">
            <br>
            <span class="style32">Názor:</span></span></span></p>
    <p><span class="style28">          
      <textarea name="nazor" cols="50" rows="3" maxlength="300"  onFocus="if(this.value=='Vas nazor...')this.value='';">Vas nazor...</textarea>
              </span>          <br>
              <input name="submit" type="submit" value="Posli" class="tlacitko">      
          </p>
  </div>
</form>

A tu ten PHP skript:

Kód: Vybrať všetko

<?php
$datum = strip_tags(trim($datum));
$nick = strip_tags(trim($nick));
$nazor = strip_tags(trim($nazor));

if (!trim($nazor) == "" OR trim($nazor) == "Vas nazor...")
{
	$datum = date("H:i:s d. m. Y");
	$nick = $_GET["nick"];
	$nazor = $_GET["nazor"];

	include "admin.php";
	$spoj = mysql_connect($host,$user,$password);
	if (!$spoj)
	{
 	die;
	 echo "Nastala chyba spojenia!!";
	}
	else
	{
	 mysql_select_db($db);
	 mysql_query("INSERT INTO board (datum,nick,nazor) VALUES ('$datum','$nick','$nazor')");
	 mysql_close($spoj);
	 echo "hotovo <meta http-equiv=\"refresh\" content=\"0; URL=board.php\">";
	}
}
else
{
echo "Musite zadat text príspevku.";
}	
?>

PHP tagy otial viem odfiltrovat aj ked je to prazdne tak to neprijme ale ked je tam napisane "Vas nazor..." tak to prijme.

upravil som ti formular o JavaScript

Kód: Vybrať všetko

<form method="get" action="posli.php">
  <div align="left" class="style27">
    <p><span class="style28"><span class="style31">
      Nick:
    </span></span></p>
    <p><span class="style28"><span class="style29">
      <input name="nick" type="text" value="Nick...." maxlength="10" onFocus="if(this.value=='Nick....')this.value='';">
      <br>
      <span class="style32">
        Názor:
      </span>
    </span></span></p>
    <p><span class="style28">         
      <textarea name="nazor" cols="50" rows="3" maxlength="300"  onFocus="if(this.value=='Vas nazor...')this.value='';" onBlur="if(this.value=='')this.value='Vas nazor...';">Vas nazor...</textarea>
       </span>          
       <br>
       <input name="submit" type="submit" value="Posli" onclick="if(this.form.nazor.value=='Vas nazor...')return false;" class="tlacitko">     
    </p>
  </div>
</form>

good luck.

//edit: samozrejme nemusim pisat, ze v pripade vypnutej podpory JSka sa to odosle.
